While Jennifer was at home taking an online exam for her business law class, a monitor（監控器）a few hundred miles away was watching her every move.
Using a web camera equipped in Jennifer’s Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked - remotely - to prevent Internet searches , and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? Or was she slowing down?
In the battle against cheating, this is the cutting edge and a key to encourage honesty in the booming field of online education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid - that students haven’t just searched the Internet to get the right answers.
Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of "open online courses." Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.
Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students’ identities using personal information, such as the telephone number they once used.
Other programs can produce unique exam by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test question are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.
小題1:Why was Jennifer watched in an online exam?

A．To correct her typing mistakes.

B．To find her secrets in the room.

C．To prevent her from slowing down.

D．To keep her from dishonest behaviors.

小題2:The underlined expression cutting edge in Paragraph 3 is closest in meaning to______.

A．The Advantages of Online Exams

B．The High-tech Methods in Online Courses

C．The Fight against Cheating in Online Education

D．The War against the Booming of Online Education

小題1:D
小題2:A
小題3:B
小題4:A
小題5:C

小題1:細節理解題根據第二段倒數第二句"and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? "可從本句得知監控Jennifer的原因是為了確保她不作弊。故選D，就是不誠實的行為。屬于上下義重現。
小題2:猜詞題根據a key to encourage 以及下一句的 the technology 可以知道答案。cutting edge與key是并列關系，同時二者都可以做到鼓勵誠實行為。前面this所指代的為上文中提到的防作弊科學技術，由此得知cutting edge應該為advanced technique。
小題3:細節理解題根據第三段 Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid -that students haven't just searched the Internet to get the right answers.可以得出答案。屬于原詞重現。本解析為名師解析團隊原創，授權獨家使用，如有盜用，依法追責！
小題4:細節理解題根據最后一段的第一句" Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones. "可知正確選項為A。此題易錯選BD。
其實選項A包含了BD選項內容。通過生成大量的有難也有易的問題，然后通過比較答題速度。屬于原詞重現。
小題5:主旨大意標題題文章主題句位于第三段第一句"In the battle against cheating, this is the cutting edge and a key to encourage honesty in the booming field of online education."可得知本文主要討論網絡課程的防作弊問題，故選C。此外，文章多次出現cheating，屬于原詞重現。

Fear may be felt in the heart as well as in the head, according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.
Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting(收縮) and pumping blood around their bodies, compared with the point when the heartbeat is relaxed. Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful event, depending on which point it is at in its regular cycle of contraction and relaxation.
Sarah Garfinkel at the Brighton and Sussex Medical School said: "Our study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart."
The study tested 20 healthy volunteers on their reactions to fear as they were shown pictures of fearful faces. Dr Garfinkel said, "The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed. Thus our hearts can also affect what we see and what we don't see - and guide whether we see fear."
To further understand this relationship, the scientists also used a brain scanner(掃描儀) to show how the brain influences the way the heart changes a person's feeling of fear. “We have found an important mechanism by which the heart and brain ‘speak’to each other to change our feelings and reduce fear," Dr Garfinkel said.
"We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced, we may be able to develop more successful treatments for anxiety disorders, and also for those for those who may be suffering from serious stress disorder."
小題1:What is the finding of the study?

A．One's heart affects how he feels fear.

B．fear is a result of one's relaxed heartbeat.

C．fear has something to do with one's health.

D．Ones fast heartbeats are likely to cause fear.

小題2:The study was carried out by analyzing _______.

A．volunteers' heartbeats when they saw terrible pictures

B．the time volunteers saw fearful pictures and their health conditions

C．volunteers' reactions to horrible pictures and data from their brain scans

D．different pictures shown to volunteers and their heart-brain communication

小題3:Which of the following is closest in meaning to "mechanism" in Paragraph 6?

A．Order.

B．system.

C．machine.

D．treatment.

小題4:This study may contribute to _______.

A．treating anxiety and stress better

B．explaining the cycle of fear and anxiety

C．finding the sky to the heart-brain communication

D．understanding different fears in our hearts and heads

Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger , but we also affect our water supply in less obvious ways. You may wonder how paving(鋪砌) a road can lead to less useable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages(短缺). Drier climates are of course more likely to have droughts(干旱) than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs.
Thinking about the way we use water every day can make a big difference, too In the United States , a family of four can use 1. 5 tons of water a day! This shows how much we depend on water to live, but there’s a lot we can do to lower the number.
You can take steps to save water in your home. To start with use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher (洗碗機)only when it is full 。Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.
小題1:Which of the following is most likely to lead to less groundwater?

A．Using river water.	B．Throwing batteries away.
C．Paving parking lots.	D．Throwing rubbish into lakes.

There is a common belief among parents that schools are no longer interested in spelling. No school I have taught in has ever considered spelling unimportant as a basic skill. There are, however, quite different ideas about how to teach it, or how much priority (優先) it must be given over general language development and writing ability. The problem is, how to encourage a child to express himself freely in writing without holding him back with spelling.
If spelling becomes the only point of his teacher’s interest, clearly a bright child will be likely to “play safe”. He will write only words within his spelling range (范圍). That’s why teachers often encourage the early use of dictionaries and pay attention to content rather than technical ability.
I was once shocked to read on the bottom of a sensitive piece of writing about a personal experience:“This work is terrible! There are far too many spelling mistakes.” It may have been a sharp criticism(批評) of the pupils technical abilities in writing, but it was also a sad thing for the teacher who had omitted (略過) to read the composition, which contained some beautiful expressions of the child’s deep feelings. The teacher was not wrong to draw attention to the mistakes, but if his priority had centered on the child's ideas, an expression of his disappointment with the presentation would have given the pupil more hope to seek improvement.
小題1:The expression “play safe” probably means ____.

A．to write carefully	B．to do as teachers say
C．to use dictionaries frequently	D．to avoid using words one is not sure of

小題2:Teachers encourage the use of dictionaries so that____.

A．students will be able to express their ideas more freely

B．teachers will have less trouble in correcting mistakes

C．students will have more trust in writing

D．students will learn to spell words correctly

小題3:The writer seems to think that the teacher’s judgement on that sensitive piece of writing is____.

A．reasonable

B．unfair

C．foolish

D．careless

小題4:The major point discussed in the passage is _______.

A．the importance of developing writing skills

B．the importance of spelling

C．the correct way of marking composition

D．the relationship between spelling and the content of a composition

At the beginning of the 20th century there were more than a million lions worldwide. Today there are less than 30,000 in the wild. The remaining lions are increasingly threatened by habitat loss, hunting and activities to protect farms and cattle.
For generations, Masai tribesmen on the large African plains in southeastern Kenya have hunted lions — to protect their farms and cattle. Today they celebrate the lions’ life.
Noah is an elder in the Masai community. “We have decided as a community of the Masai to lay down our spears, and there will be no more killing of lions in our community.” He is part of a group of Masai visiting the United States promoting (推廣) the Predator Compensation Program.
Conservation International’s Frank Hawkins explains, “The Masai have been living with wildlife for many generations and it has been a conflicting ( 有沖突的) relationship in many ways. They compete with the animals for food as lions eat their cattle. We’re trying to find ways in which the wildlife will become something useful to them.” They had the Predator Compensation Fund founded in 2003. After much discussion, a group of Masai farmers agreed to protect lions. In turn, if lions or other predators kill their cattle, the Masai owner will be paid market value for the dead animals from the fund.
One man said that in the past, when a lion killed cattle, they killed it immediately. And now, after the start of the program, the Masai see the lion population growing. Since 2003, only four lions have been killed here.
小題1:What is the aim of the Predator Compensation Program?

A．To protect people in the wild.	B．To protect Masai’s farms.
C．To protect lions only.	D．To protect the wildlife.

小題2:According to the passage, why haven’t Masai tribesmen killed many lions since 2003?

A．Because lions don’t eat their cattle any more.

B．Because they will be fined if they kill lions there.

C．Because the fund will pay for dead animals killed by lions

D．Because there are less than 30,000 lions in the wild now.

小題3:What do you think of the Masai ?

A．Wise.

B．Mean.

C．Generous.

D．Stupid.

You can’t hide a natural disaster from children, so how do we prepare them for it? First of all, you should explain to them that acts of nature aren’t necessarily disasters but can become one. These may include floods, hurricanes, tornadoes, winter storms, wild fires, and earthquakes. The way to prepare children for these disasters is to educate them about what each type is and then make it fun by making them “Disaster Masters” or whatever title you can think of.
Making them a Disaster Master won’t be easy. They must know what’s in a disaster emergency kit(工具箱) and why it’s included. You can get your friends involved, too. If your friends have children, they may want to be involved in your emergency preparations. Make it a group project. This is the opportunity for everyone to become familiar with the equipment.
We have to be aware of our conduct and the way we react to stress. The children will be easily influenced by your attitude and demeanor. The calmness, steady manner, and good humor of your spouse (配偶) and you will go a long way toward the easing or the reduction of stress.
Explain to them what they’re likely to encounter or see and describe how people may react. Disasters can come and go very quickly and generally don’t last long. If you must stay away from home, try to get into a routine quickly and encourage them to make new friends. Let them know they can look to their parents and other adults if they become scared or confused. And it’s important to let them know it’s OK to cry during a disaster.
It’s sometimes helpful to let the children draw pictures of what they’ve experienced. Encourage them to write what they learned and what could have been done better. Save the story. Make it part of a documented family history!
小題1:This passage was written mainly to tell us about ______.

A．the importance of mutual help in disaster preparation

B．tips for preparing children for a natural disaster

C．the importance of educating children about natural disasters

D．ways to raise children’s courage in natural disasters
