Nature is full of color, from rainbows and roses to butterfly wings and peacock tails. Even the fruits and vegetables you eat have different colors: blue blueberries, red strawberries, green broccoli, and orange carrots.
Plant and animals often use color to attract attention. The substances responsible for these colors belong to a class of chemical called antioxidants(抗氧化物). Plants make antioxidant to protect themselves from the sun’s ultraviolet(UV)(紫外線)light.
Ultraviolet light causes chemicals called free radicals(自由基)to form within plant cells. They can destroy parts of plant. Free radicals also have damaging effects on human beings. Some of these effects like wrinkled skin can be seen. The damage is caused by the free radicals attacking cells in our bodies. Certain cancers and heart disease are linked to free radicals.
Our bodies have natural defences for fighting off free radicals. While we are young, our defences are pretty strong. However, they get weaker as we get older. The body’s built-in defences can only go so far without extra help.
The key to fighting free radicals with fruits and vegetables is to mix and match colors. It’s like sunscreen(防曬霜)for the inside of your body. Go for a range of very bright colors. Colorful foods contain hundreds of healthy chemicals not found anywhere else.
Research into how chemicals in blueberries affect the brain’s function in rats suggests that these chemicals may help our own brains work more efficiently.
Don’t just blame the sun. Ultraviolet light isn’t the only source of free radicals. If you breathe polluted air such as smog, automobile exhaust(廢氣), or wasted gas from a factory, you take in chemicals that also cause such damage. And, the body itself produces free radicals as it processes food.
小題1:Which of the following not true?

A．Antioxidants are responsible for plant colors

B．Plants use color to attract attention

C．Antioxidants can protect plants from UV light

D．Antioxidants help free radicals to attack plants

小題2:In which order do the following facts occur?
a Wrinkled skin can be seen
b UV light causes free radicals to form
c Free radicals damage cells in our bodies
d The sun gives out UV light

A．a,b,c,d	B．d,b,c,a
C．c,a,d,b	D．d,b,a,c

小題3:We need extra help for fighting off free radicals from fruits and vegetables because ____.

A．our bodies’ defences are not natural

B．we are too young to defend ourselves

C．our defences get weaker as we get older

D．our bodies’ built-in defences can only go away

小題4:Which of the following can not cause free radicals to form?

A．Colorful food	B．UV light from the sun
C．Polluted air	D．The body itself

小題1:D
小題2:B
小題3:C

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.

American researchers found females are the more talkative sex because of a special “l(fā)anguage protein(蛋白質)” in the brain.
The study, conducted by neuroscientists （神經(jīng)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 to

C．put pressure on

D．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 rats	B．Why women are the talkative sex
C．Sex differences in Foxp2 protein	D．Foxp2 protein determines oral ability

Recently, a student used his Personal Digital Assistant (PDA) to film a female teacher scolding and tearing the work of a classmate. The public discussion that the incident caused started on the Internet. However, when it came to the media’s attention, it quickly became a major topic in the education circles. The reactions so far suggest that the focus of the debate has been on one question: whom to blame?
Teachers who are anxious to defend their professional dignity have tried to put the blame on the students. They mentioned their right to privacy 隱私）and for this reason they requested the Ministry of Education (MOE) to prohibit PDAs in schools. On the other hand, some parents and students have taken a different position. They feel that the teacher is also at fault. Caught up in the war of words between both sides, people are no longer interested in the “truth” of the matter which seems now unimportant. It was left to newspapers to discover the central point of the controversial issue, by stressing the problems that are not always easily noticed in our educational system.
For those responsible for educating the young, this PDA incident conveys the message that “Times have changed”，a reality that must have been felt even more strongly by the female teacher when reflecting on this unpleasant experience. Different times call for different professional approaches in education. The ability to understand the students they are teaching has always been the quality of successful teachers. Despite some factors, the incident shows that the teacher lacks good qualities on her part. Besides, the rules under current system to deal with recalcitrant students need to be improved. Also, it is an example which shows the issue we are familiar with: what to do with new technology? With PDA, the new technology, the interaction (交流）between the teacher and students in classroom has been changed.
小題1:The author’s purpose in writing this passage is to______.

A．improve the teachers’ way of teaching

B．stress the using of PDA in the classroom

C．change the students’ behavior in the classroom

D．discuss the potential problems of educational system

小題2:The underlined word “recalcitrant” in paragraph 3 probably means______?

A．difficult to control	B．interested in nothing
C．unwilling to learn	D．ready to obey rules

小題3:The writer’s attitude toward the PDA incident is______.

A．optimistic	B．critical
C．uncertain	D．approval

小題4:What might be the best title for the passage?

A．Whom to blame?

B．The PDA incident

C．Times have changed

D．What to do with new technology?

Become a confident speaker. How to improve your English speaking skills and make you able to communicate more easily and effectively? The following tips will help you to become a more confident speaker.
Practice where you can and when you can. And practice is good — whether you speak to someone who is a native English speaker or not.
It’s important to build up your confidence. If possible, use the simple sentence structure that you know is correct, so that you can concentrate on getting your message across.
Try to experiment with the English you know. Apply (應用) words and phrases you know to new situations. Native English speakers are likely to correct you if you use the wrong word. They usually don’t mind if you use wrong grammar.
Try to respond to what people say to you. You can often get clues to what people think by looking at their body language. Respond to them in a natural way.
Never translate everything into your own language. It takes you much time and you’ll find it difficult to find an English answer right away. You don’t know how to do well. The more you want to act well, the more slowly you act. This will make you hesitant.
If you forget a word, do what native English speakers do all the time, and say things that ‘fill’ the conversation. This is better than remaining completely silent. Try using ‘um’, ‘er’, if you forget the word.
Don’t speak too fast! It’s important to use a natural rhythm (節(jié)奏) in speaking English, but if you speak too fast it will be difficult for people to understand you.
Try to relax when you speak, and you’ll find that your mouth does most of the pronunciation work for you. Speak English at a normal speed.
Final tips: Try to become less hesitant. Don’t be shy to speak — the more you do it, the more confident you’ll become. Remember to be polite — use “please” and “thank you” if you ask someone to do something for you.
小題1:What is the text mainly about?

A．Good ways of studying English well.

B．Suggestions on becoming a confident speaker.

C．Things to pay attention to when speaking English.

D．How to correct your mistakes as you speak English.

小題2:How many tips does the author offer in this text?

A．9.

B．10.

C．11.

D．12.

小題3:In this passage, the underlined word “hesitant” in the sixth paragraph means “________”.

A．sure about what to do

B．fast to make a good decision

C．successful in answering questions

D．uncertain about how to express yourself

小題4:This text is most probably written for ________.

A．English beginners	B．native English speakers
C．English teachers	D．language experts

Living in a modern society with more and more out-of-date but still useful computers, many people have to face such a troubling problem: How to deal with those old computers? Some old ones are put away in homes. Many more are just thrown out with the rubbish.
Don’t worry! Some companies are coming up with new ways to cut the number of old computers. Sony, Dell, Hewlett-Packard and other companies now agree to take back some old computers.
In some countries, there are laws about what to do with old computers. By law, computer companies will have to pay for collecting and recycling their used products. And 70% of computer waste must be recycled. The idea behind the laws is that computer companies themselves should pay the cost. That will encourage them to make computers that are easier and cheaper to repair and upgrade（升級）.
While many people are throwing away good computers, others cannot afford them at all. Hundreds of organizations（組織）are working to solve this problem. They collect and repair old computers before sending them to schools, charities（慈善團體）and people who need them. In this way, we can turn one person's rubbish into someone else's useful things-and cut down on waste.
小題1:What do many people do with old computers?

A．They sell them to others.

B．They try to repair them.

C．They give them to others.

D．They stop using them

小題2:According to laws in some countries mentioned in the passage, computer companies must_____.

A．recycle most of their products

B．make their computers cheaper

C．repair and upgrade old computers

D．collect all their used products

小題3:The last paragraph mainly tells us that hundreds of organizations are working to _________.

A．help the computer companies to collect old ones

B．repair old ones and send them to whoever needs them.

C．advise people not to throw away good computers.

D．encourage people to turn rubbish into useful things.

小題4:What is the main idea of this passage?

A．How to repair old computers.

B．Avoid producing too many computers.

C．Encourage to recycle old computers.

D．How to turn rubbish into useful things
