【題目】The baby is just one day old and has not yet left hospital. She is quiet but alert（警覺(jué)）. Twenty centimeters from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze（凝視）starts to lose its focus--until a third, with three black spots, is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?
Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise（同樣地）when the researchers started with drumbeats and moved to spots.

【1】The experiment described in Paragraph 1 is related to the baby’s .

A. sense of hearing B. sense of sight

C. sense of touch D. sense of smell

【2】Babies are sensitive to the change in _______.

A. the size of cards B. the colour of pictures

C. the shape of patterns D. the number of objects

【3】Why did the researchers test the babies with drumbeats?

A. To reduce the difficulty of the experiment.

B. To see how babies recognize sounds.

C. To carry their experiment further.

D. To keep the babes interest.

【4】Where does this text probably come from?

A. Science fiction. B. Children’s literature.

C. An advertisement. D. A science report.

【答案】

【1】B

【2】D

【3】C

【4】D

【解析】試題分析: 本文對(duì)剛出生一天的嬰兒做實(shí)驗(yàn)，通過(guò)變化紙上的黑點(diǎn)及鼓的敲打次數(shù)對(duì)嬰兒的視覺(jué)、聽(tīng)覺(jué)進(jìn)行的一個(gè)實(shí)驗(yàn)。

【1】B 考查細(xì)節(jié)理解題。根據(jù)文章第一段文中的She stares it carefully. Her gaze starts to lose its focus.可知，本段是對(duì)孩子的視覺(jué)實(shí)驗(yàn)，故選B項(xiàng)。

【2】D考查細(xì)節(jié)理解題。根據(jù)第一段中的As the cards change from one to the other，her gaze(凝視)starts to lose its focus—until a third，with three black spots，is presented.Her gaze returns...可知，隨著卡片上黑點(diǎn)數(shù)量的變化，嬰兒的注視也發(fā)生變化，表明了嬰兒對(duì)于數(shù)量的變化比較敏感，故選D項(xiàng)。

【3】C考查細(xì)節(jié)理解題。第二段中研究人員先是通過(guò)卡片上的黑點(diǎn)來(lái)測(cè)驗(yàn)嬰兒對(duì)于數(shù)量的變化的敏感程度；根據(jù)第二段中的The effect even crosses between senses...three drumbeats than when they heard just two；likewise(同樣地)when the researchers started with drumbeats and moved to spots.可知，研究人員又做了擊鼓的實(shí)驗(yàn)，這樣做的目的是更加深入地研究嬰兒對(duì)于數(shù)量變化的敏感程度，故選C

【4】D 考查推理判斷題。本文提到了experiment和researchers等，可知是一些研究人員做了一個(gè)實(shí)驗(yàn)，來(lái)檢驗(yàn)嬰兒們對(duì)于數(shù)量的變化是不是敏感，所以本文屬于一個(gè)科學(xué)研究報(bào)告，因此選D

【題目】閱讀下面短文，根據(jù)所給情節(jié)進(jìn)行續(xù)寫(xiě)，使之構(gòu)成一個(gè)完整的故事。

Several years ago, I was living in New York and working for an airline, so I never got back home for Christmas. My Christmas was happy too with some other colleagues around. But in my heart I was sad because I couldn’t stay with my family. Sometimes my colleagues would say our Christmas was filled with tears. But this Christmas was different. I was lucky. I had the whole day off, which meant I could stay with my family on Christmas Eve.

When Christmas morning came, I awoke to a small hand rubbing my face. “Dad, Merry Christmas!” was all my younger son had time to say. He seemed to be racing against time. I knew he was hunting for gifts with his brother eagerly. I got downstairs just to see the two little boys’ faces as they looked at the pocket rockets Santa Claus had left them. I realized that the real Christmas was for the children who had deep belief in the amazing power of Santa Claus. At first, their fingers went almost shyly over their toys. When their inspection had been completed, the two boys ensured that the gifts were really delivered by Santa Claus and they dragged everything into the center of the living room.

Delight flooded the room. As their mother began giving out gifts, I smiled to myself, wondering how my unexpected gifts this year would be received. With so many Christmas spent outside, I had prepared so many gifts for my children and together with my wife I hid them in several secret places. But the children were excellent detectives and they found all of them. They were happily opening packages constantly thanking considerate Santa Claus for his kindness and ability to know their desires. But I had not received a single one. I knew they had forgotten my existence with my absence from their Christmas these years.

【題目】Four simple ways to stay positive

Trying to stay positive, both in good times and bad, is a great way to improve your quality of life. Try these four methods on a daily basis.

1. Don't think a lot about negativity.

Of course. Staying positive 24 hours a day, seven days a week is a bit difficult. Letting things get to you is normal, and it's actually healthy to cry or express frustrations once in a while. It's when those negative moments control your life that your emotional balance is at risk. 【1】 However, don't give that sadness another second in your day.

2.【2】.

What you put into your body directly affects how you feel on the outside. Fill yourself with good, healthy foods like fruits and vegetables and limit snacking. Exercise is equally of great importance. Take-a few days out of your week for at least a half a hour of activity, and try to stick to a routine.【3】

3. Be kind to others.

【4】 Making someone's day a bit brighter not only puts a smile on his or her face, but also yours as well. Remember to smile and treat each person with pity and respect. Good deeds are contagious (傳染的）, and your positive attitude may spread among others.

4. Take it one day at a time.

Being positive isn't an instant thing. It's a steady effort that we follow every hour of every day. 【5】 Instead, focus on living in the moment and doing what you can to make each moment better.

A. Eat healthy and stay fit.

B. Take your lunch breaks outside.

C. Don't worry about what the future may bring.

D. Gratefulness helps you appreciate life in bad times.

E. Good feelings come from acts of kindness and selflessness.

F. Take a few minutes lo feel sad and accept what happened.

G. Even going outside for a walk and enjoying the sunshine improves your mood.

【題目】An environmental group called the Food Commission is unhappy and disappointed because of the sales of bottled water from Japan. The water, it angrily argues in public, has traveled 10,000 “food miles” before it reached Western customers. Transporting water halfway across the world is surely the extremely stupid use of fuel when there is plenty of water in the UK. It is also worrying that we were wasting our fuel by buying prawns from Indonesia (7,000 food miles ) and carrots from South Africa (5,900 food miles).

Counting the number of miles traveled done by a product is a strange way of trying to tell the true situation of the environmental damage due to industry. Most food is transported around the world on container ships that are extremely energy efficient. It should be noticed that a ton of butter transported 25 miles in a truck to a farmers’ market doesn’t necessarily use less fuel on its journey than a similar product transported hundreds of miles by sea. Besides, the idea of “food miles” ignores the amount of fuel used in the production. It is possible to cut down your food miles by buying tomatoes grown in Britain rather than those grown in Ghana. The difference is that the British ones will have been raised in heated greenhouse and the Ghanaian ones in the open sun.

What is the idea of “food miles” does provide, however, is the chance to cut out Third World countries from First World food markets. The number of miles traveled by our food should, as I see it, be regarded as a sign of the success of the global trade system, not a sign of damage to the environment.

【1】The Food Commission is angry because it thinks that ________.

A. UK wastes a lot of money importing food products

B. some imported goods causes environmental damage

C. growing certain vegetables causes environmental damage

D. people wasted energy buying food from other countries

【2】The phrase “food miles” in the passage refers to the distance ________.

A. that a food product travels to a market

B. that a food product travels from one market to another

C. between UK and other food producing countries

D. between a Third World country and a First World food market

【3】By comparing tomatoes raised in Britain and in Ghana, the author tries to explain that ________.

A. British tomatoes are healthier than Ghanaian ones

B. Ghanaian tomatoes taste better than tomatoes ones

C. cutting down food miles may not necessarily save fuel

D. protecting the environment may cost a lot of money

【4】From the passage we know that the author is most probably ________.

A. a supporter of free global trade

B. a member of a Food Commission

C. a supporter of First World food markets

D. a member of an energy development group

【題目】根據(jù)短文內(nèi)容，從短文后的七個(gè)選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。

How northern Europeans beat the winter blues

Ask a child from northern Europe to draw two pictures—one on a rainy day and a second in the sunshine—and this is what you will get: in the first, as raindrops fall from the top of the page, the man behind the window has an unhappy expression. When a yellow sun sends out some light from the corner, the man is smiling.

Northern Europeans associate rain with sadness and sunshine with happiness. They think this is true because they are so aware of how their environment affects them.【1】In October 2008, a group of researchers examined the influence of different daily weather factors, including temperature, wind and sunlight, on 1,200 participants. The conclusion was that good or bad weather had little effect on people’s feelings.【2】A person who is upset on dark or cold days suffers from a negative mood(情緒), and he will be likely to experience a sad winter. This is the basis of an illness called Seasonal Affective Disorder (SAD).【3】

AniKalayjian, professor of psychology at Fordham University, advises that we should take steps to strengthen the brain’s system against weather-driven mood changes. Research on SAD has been focused on the brain’s response to darkness and light. When our eyes detect darkness, the brain gives off melatonin, which starts sleep cycles.【4】It takes over to help us wake up and feel better when we detect light. “We can encourage people to take charge of their feelings,” says Kalayjian. “We tell them to leave the computers and the indoor games and get out there in the sun.【5】”

A day of rain can potentially destroy your plan and affect your mood. But as the Scottish comedian Billy Connolly once said: “There is no such thing as bad weather, only the wrong clothing.”

A. Yet that link has no scientific basis.

B. It is seriously doubted among the people who suffer from SAD.

C. It affects about10% of the population of northern Europe each year.

D. Another chemical called serotonin, however, can make people happy.

E. That’s when people can recharge their serotonin and get a better mood.

F. Most studies prove that a negative feeling is associated with bad weather.

G. They determined that people actually differ in their sensitivity to weather changes.

I was really sad while I found my bicycle went wrong again. Tired of repairing it again and again, I decided buy a new one. After school, I went to a shop locating in the center of the city with a friend called Jack. The black bicycle attracted my eyes as soon as we went into the store. It looked very cool that I could hardly wait to ride ft. The shopkeeper told us that it was the latest style. He wanted to charge me for 800 yuan, that was too high for me. I just couldn’t afford such an expensive one. Then I choose another one, which cost him only 200 yuan. It was not perfect, so it was much better than the old one.
