根據短文內容,從下框的A—F選項中選出能概括每一段主題的最佳選項。選項中有一項為多余項.
A.Join learning communities and help each other.
B.Expect problems, never be disappointed, and gradually you’ll make it.
C.Anytime is learning time.
D.Get interested and arouse(喚起) your desire for knowledge.
E.Cover the same ground from different angles(角度).
F.Try to be a good and effective learner.
As a student, how we can learn our lessons effectively is a common problem which is always puzzling us.If you follow suggestions below, I'm sure you'll find the solution easily.
小題1:Your interest in the subject is the essential driver of success. You can' t learn what you do not want to learn. Emotion is an important part of the learning process. If you are even moderately interested in a subject, give yourself a chance. The key is to get started. If you can create some pleasurable routines, you may find that the subject grows on you. You must always remember learning is just like eating. You don' t expect to enjoy your food without appetite(食欲).Therefore, you should always try to arouse your interest and desire for knowledge if you want to learn well.
小題2:Don't expect to understand things, or remember too much, the first time you study them.Think about what problem you will meet with in your study, so that you are well-prepared for it. Never be disappointed no matter what happens. Trust that things will get clearer as your brain comes to get new information. It is like a jig-saw puzzle or a cross-word puzzle(縱橫填字游戲). As you start to put the pieces together, or string the words together, the full picture becomes clearer. The brain learns all the time, but on its own schedule.Learning does not take place according to a schedule laid down by a curriculum or teacher. Keep at it, and you will gradually find that things that seem difficult at first, will become second nature with time.
小題3:Your brain is struggling to form patterns to cope with new input from your learning activities.Sometimes, no matter how long you focus on one subject, your brain is not going to pick it up.If you are stuck, move on.Then cover the same general information from a different source, a different book, or a blog, or an online lecture or a video.Try to become a grazing learner, wandering about the countryside, rather than a feed-lot learner, just standing there in one spot, chewing the same bale of hay.The broader your base, the easier it is to learn.Just as the "rich get richer" , the more you know, the more you can learn.
小題4:Take full advantage of the Internet, blogs, and various mobile devices, not to mention good old-fashioned books and magazines.Learn during "dead time". Listen in your car, on the train, or while jogging. Have your learning with you while waiting in the doctor's office, or listen while checking out at the supermarket. Anytime is learning time.Remember, you are learning through exposure, not by nailing things down. It is more like moisture accumulation in a cloud, rather than building a brick wall.
小題5:The "loneliness of the distance learner" is a thing of the past.Join a learning community on the web, where members share their knowledge and experience. Search for the communities that suit your interests and learning styles. You will find encouragement, advice and stimulus from fellow learners, as well as from tutors, teachers and coaches.In these communities, you can measure your progress against your own goals, or compare your experience with that of other learners.You can even teach and help others, which is a great way to learn.

小題1:D
小題2:B
小題3:E
小題4:C
小題5:A

試題分析:本文是關于如何更為有效的進行學習的話題,并提出了多種合理化的建議。
小題1:D 根據本段第一句Your interest in the subject is the essential driver of success.說明興趣 是成功的關鍵,故D項內容與本段相符。
小題2:B 根據本段第一句和最后一句Keep at it, and you will gradually find that things that seem difficult at first, will become second nature with time.和Don't expect to understand things, or remember too much, the first time you study them.都說明我們要堅持下去,不要泄氣,這樣就會讓我們慢慢取得進步,最后取得成功。
小題3:E 根據本段5,6,7行Try to become a grazing learner, wandering about the countryside, rather than a feed-lot learner, just standing there in one spot, chewing the same bale of hay.說明我們要站在不同的立場上來看待這樣的問題,這樣會更為全面。故E項與本段相符。
小題4:C 根據第一句Take full advantage of the Internet, blogs, and various mobile devices, not to mention good old-fashioned books and magazines.說明我們要利用一切能夠利用的機會進行學習。故C項與本段相符。
小題5:A 根據本段前三行The "loneliness of the distance learner" is a thing of the past.Join a learning community on the web, where members share their knowledge and experience. Search for the communities that suit your interests and learning styles.說明要全面加入社團,在團體里相互幫助,最后取得成功。
點評:本文是關于如何更為有效的進行學習的話題,從題目設置的角度看,本題側重對學生把握文章中心段落和各段落的中心句的能力的考查,所以遇到這類題后,要注意把握好文章結構,了解文章中心意思,找到各段落中心句。不要讓文中的一些生詞影響了注意力。

These days, young children can enjoy directly what it is like to be a marine biologist (海洋生物學家) at a marine association. What they discover can lead them to appreciate and protect the ocean and also the animals living in it.
At the present time, learning isn’t only limited to the classroom. It’s quite common for kids to learn from outdoor experiences. Teachers commonly take their pupils on field trips to museums as well as other interesting areas. If you wish to help pupils to take care of the ocean, one of the best areas to take them to is a marine association, the place where the ocean biome (生物圈) is shown.
Taking your pupils to a marine association is a prefect way to help them learn. Education professionals agree that there are topics that children can learn more successfully whenever they experience them directly.
Several organizations that focused on protecting the ocean now operate on the coast of different areas in America and all around the world. It’s quite common for marine associations nowadays to open their doors several times a week to kids, parents, and ocean lovers to learn more about the ocean biome.
A marine association has different programs for children of different ages. You’ll find programs that are developed specially for pupils. Pupils are involved in interactive (互動的) learning. This learning experience allows young children to recognize the value of the role each species performs in their environment. They not only get to research creatures from the ocean, but they also get to see, touch, and smell most of these animals and plants. This type of exposure offers students an idea about the life of a marine scientist. It could help them choose a career afterwards.
These programs are generally held on Saturdays and Sundays in order that kids and parents can have more hours in which to have fun. Teachers who want to arrange these activities for their students can call a local marine association near them.
小題1:According to the text, pupils can have a better understanding of the ocean biome by _______.
A.learning about it from books
B.going to a marine association
C.attending marine biologists’ meetings
D.taking part-time jobs at marine associations
小題2:In Paragraph 5, the author mainly wants to tell us _______.
A.the advantage of learning at a marine association
B.different activities offered by a marine association
C.a marine association’s working conditions
D.the way to develop children’s interest in ocean
小題3:The underlined word “exposure” in Paragraph 5 probably means _______.
A.the way of explaining something
B.the way of choosing a career
C.a marine association’s working condition
D.the way to develop children’s interest in the ocean
小題4:Which of the following is TURE?
A.Young children can enjoy indirectly what it is like to be a marine biologist at a marine association.
B.To help your pupils to take care of the ocean, the best area to take them to is a marine association.

小題5:The text is most probably taken from _______.
A.a teacher’s presentation
B.a marine biologist’s report
C.a student’s field trip journal
D.an introduction to a marine association

When prehistoric man arrived in new parts of the world, something strong happened to the large animals; they suddenly became extinct. Smaller species survived; the large, slow-growing animals were easy game, and were quickly hunted to extinction. 
Now something similar could be happening in the oceans. That the seas are being over-fished has been known for years and researchers such as Ransom Myers and Boris Worm have shown how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) inanes fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then.
Dr. Worm acknowledges that these figures are conservative (保守的). One reason for this is that fishing technology has improved. Today’s vessels can find their prey using satellites and sonar, which were not available 50 years ago. That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines would have been more saturated with fish. Some individuals would therefore not have been caught, since baited hooks would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around noise.
Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the date support an idea current among marine biologists, that of the “shifting baseline”. The notion is that people have failed to detect the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past. That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels. Most fisheries are well below that, which is a bad way to do business.
小題1:The aim of the extinction of large prehistoric animals is to suggest that _______.
A.large animal were not easy to survive in the changing environment
B.small species survived as large animals disappeared
C.large sea animals may face the same threat today.
D.Slow-growing fish outlive fast-growing ones
小題2:We can infer from Dr Myers and Dr. Worm’s paper that _______.
A.the stock of large predators in some old fisheries has reduced by 90%
B.there are only half as many fisheries are there were 15 years ago
C.the catch sizes in new fisheries are only 20% of the original amount
D.the number of larger predators dropped faster in new fisheries than in the old
小題3:By saying these figures are conservative (line 1, paragraph 3), Dr worm means that_______.
A.fishing technology has improved rapidly
B.then catch-sizes are actually smaller then recorded
C.the marine biomass has suffered a greater loss
D.the date collected so far are out of date.
小題4:Dr Myers and other researchers hold that _______.
A.people should look for a baseline that can’t work for a longer time
B.fisheries should keep the yield below 50% of the biomass
C.the ocean biomass should restore its original level.
D.people should adjust the fishing baseline to changing situation.
小題5:The author seems to be mainly concerned with most fisheries’ _______.
A.management efficiency
B.biomass level
C.catch-size limits
D.technological application.

When children learn a language, they learn the grammar as well as words or vocabulary. No one teaches them; children just “pick them up”.
Before babies begin to produce words, they produce sounds. Some of these sounds will remain if they occur in the language being learned, and others will disappear. This is called the “babbling stage”.
A child does not learn the language “all at once”. The child first speaks only one-word “sentences”. After a few months, the two-word stage arises. During this stage, the child puts two words together. These two-word sentences have definite patterns and express grammatical and meaningful relationships. Still later, in the telegraphic stage, the child will produce longer sentences. These longer sentences are mainly made up of content words. The child’s early grammar lacks many of the rules of the adult grammar, but gradually it will become perfect.
All normal children everywhere learn language. This ability is not dependent on race, social class, geography, or even intelligence (智力). This ability is uniquely (獨特的) for human.
小題1:This passage is mainly about ___________.
A.differences between a child’s language and an adult’s
B.ways of teaching babies to talk
C.children’s learning of the mother language
D.the importance of learning foreign languages
小題2:The phrase “pick them up” means____________.
A.raise them from the ground
B.learn them without much effort
C.use hands to help carry them
D.study very hard and remember them
小題3:During the “babbling stage”, babies ___________.
A.can only produce sound
B.learn to work without falling over
C.can understand people’s talk
D.begin to produce two-word sentences
小題4:The two-word sentences produced by babies __________.
A.are simpler than those produced in the “babbling stage”
B.are much more difficult than those produced in the telegraphic stage
C.are strictly grammatical
D.are meaningful and have function
小題5:The passage implies that any children can learn a language as long as he is ___________.
A.well-educatedB.clever enough
C.uniqueD.physical normal

Words can hurt
I remember the pain most vividly. My stomach was sick, my heart hurt, and my eyes stung(刺痛的) from holding back tears.
“you know, Autumn,” my friend Nick said, “Lisa and Andrea were just talking about you.” I immediately got nervous. “They said that the only reason you start on the basketball team is because the coach (教練)likes you .It’s not because you’re good.” I might be sick. “They said they’re tired of you always getting what you want.”
I struggled to keep myself from crying, sinking(下沉) to my knees on the cold floor. After Nick told me everything my supposed best friends said about me, I was hurt.
Lisa and Andrea came in from lunch break acting as if nothing had happened . Lisa was still my deskmate, and Andrea was still my partner for our history project.
I was amazed at their ability to pretend we had the perfect friendship, especially since they’d said such hurtful things.
I was a freshman in high school, and I felt like I didn’t have a friend in the world, all because of a rumor(謠言).
The tongue can be our worst enemy. Rumors harm confidence(信心) and separate close friends. They are like sharp knives, cutting one’s dignity(尊嚴) into pieces. When we say unkind things about others, we’re thrusting(插) knives into their hearts.
So how was I to act next? When Lisa and Andrea pretended our friendship hadn’t changed, I thought of attacking them back. But instead, I told them directly that they had hurt me. Lisa started crying and Andrea was speechless. I know they were both sorry for what they had said. They apologized, and I forgave them with grace(優雅). Sure, things were a little awkward(尷尬) at first, but soon enough everything was back to the way it had been before.
I still deal with gossip(流言), sometimes as a recipient(接受者) and sometimes as a participant(參與者). But the more I learn about love, the more I realize the importance of encouraging others- sometimes gossip never does.
小題1:What word can exchange the underlined word in para1?

American researchers found females are the more talkative sex because of a special “language protein(蛋白質)” in the brain.
The study, conducted by neuroscientists (神經學家)and psychologist from the University of Maryland, concluded that women talked more because they had more of the Foxp2 protein. The research, published in the Journal of Neuroscience, found that higher levels were found among humans that were women but in rats that were males. Their findings came after it was previously claimed that ladies speak about 20,000 words a day – over 13,000 more than men. "This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals,” said Prof Margaret McCarthy, who led the study. In their study, the researchers attempted to determine what might make male rats more vocal than their female friends.
They separated four-day-old rats from their mothers and then counted the number of times they cried out in the “ultrasonic range”, the frequencies higher than humans can hear, over five minutes. While both sexes called out hundreds of cries, the males called out twice as often, they found. But when the pups were returned to their mother’s cage, she fussed over her sons first. Tests conducted on the parts of the brain known to be associated with vocalcalls showed the male pups have up to twice as much Foxp2 protein as the females. The researchers then increased the production in the brains of female pups and reduced it in males. This led to the female rats crying out more often and their mothers showing more interest to them. In contrast, males became less “talkative”.
The researchers then tested samples from ten children, aged between three and five, which showed that females had up to 30 per cent more of the Foxp2 protein than males, in a brain area key to language in humans.
“Based on our observations, we assume higher levels of Foxp2 in girls and higher levels of Foxp2 in male rats is an indication that Foxp2 protein levels are associated with the more communicative sex,” said Prof McCarthy.
"Our results imply Foxp2 as a component of the neurobiological basis of sex differences in vocal communication in mammals."
小題1:From the second paragraph, we can learn that ________.
A.women always speak more words than men
B.men and male rats have low levels of language protein
C.women and male rats have similar levels of Foxp2
D.McCarthy isn’t the first to find females more talkative
小題2:The underlined phrase “fussed over” in the third paragraph probably means______.
A.paid attention to B.related toC.put pressure onD.counted on
小題3:The researchers carried out the experiments on rats in order to _______.
A.test which part of the brain is key to language in rats and humans
B.prove the levels of Foxp2 protein in humans and rats are different
C.determine the reason why female rats are more talkative than male rats
D.discover the association between Foxp2protein and vocal communication
小題4:Which of the following can be the best title for the passage ?
A.Tests on humans and ratsB.Why women are the talkative sex
C.Sex differences in Foxp2 proteinD.Foxp2 protein determines oral ability

Once my mother told me a story that in Africa, when an antelope (羚羊) wakes up every morning, the first thing it thinks about is, “I must be 36 to run faster than the fastest lion, or I will be killed.” 37 , a lion wakes from his dream.
