The baby is just one day old and has not yet left hospital. She is quiet but alert（警觉）. 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 gave（凝视）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（同样地）when the researchers started with drumbeats and moved to spots.
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

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.

Where does this text probably come from?

A．Science fiction	B．Children’s literature
C．An advertisement	D．A science report

Your glasses may someday replace your smartphone, and some New Yorkers are ready for the switch. Some in the city can't wait to try them on and use the maps and GPS that the futuristic eyewear is likely to include.
" I'd use it if I were hanging out with friends at 3 a. m. and going to the bar and wanted to see what was open," said Walter Choo, 40, of Fort Greene.
The smartphone-like glasses will likely come out this year and cost between $250 and $600, the Times said, possibly including a variation of augmented(增强的) reality, a technology already available on smartphones and tablets (平板电脑) that overlays information onto the screen about one's surroundings. So, for example, if you were walking down a street, indicators would pop up showing you the nearest coffee shop or directions could be plotted out and come into view right on the sidewalk in front of you.
" As far as a mainstream consumer product, this just isn't something anybody needs," said Sam Biddle, who writes for Gizmodo.com. " We're accustomed to having one thing in our pocket to do all these things," he added, "and the average consumer isn't gonna be able to afford another device (装置) that's hundreds and hundreds of dollars. "
9to5Google publisher Seth Weintraub, who has been reporting on the smartphone-like glasses since late last year, said he is confident that this type of wearable device will eventually be as common as smartphones.
"It's just like smartphones 10 years ago," Weintraub said. "A few people started getting emails on their phones, and people thought that was crazy. Same kind of thing. We see people bending their heads to look at their smartphones, and it's unnatural," he said. " There's gonna be improvements to that, and this a step there. "
One of the possible functions of the smartphone-like glasses is to ____.

A．program the opening hours of a bar

B．supply you with a picture of the future

C．provide information about your surroundings

D．update the maps and GPS in your smartphones

The underlined phrase "pop up" in the third paragraph probably means " ____".

A．develop rapidly	B．get round quickly
C．appear immediately	D．go over automatically

According to Sam Biddle, the smartphone-like glasses are ____.

A．necessary for teenagers

B．attractive to New Yorkers

C．available to people worldwide

D．expensive for average consumers

We can learn from the last two paragraphs that the smartphone-like glasses ____.

A．may have a potential market

B．are as common as smartphones

C．are popular among young adults

D．will be improved by a new technology

Bamboo (竹子) is one of nature’s (自然) most surprising plants. Many people call this plant a tree, but it is a kind of grass.
Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist reported one bamboo plant which grew 1.5 metres (4 feet) in 24 hours! Bamboo grows almost everywhere in the world except Europe. There are more than 1, 000 kinds of bamboo.
Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimeters wide while others may grow to more than 30 centimetres (1 foot) across. This plant also comes in different colors, from yellow to black to green.
Bamboo has been used to make many things such as hats and kitchen tools. Because it is strong, bamboo is also used to build buildings.
Many Asian countries have used bamboo for hundreds of years. They often use bamboo for buildings and supporting new buildings and bridges while they are being built.
In Africa, poor farmers are taught how to find water using bamboo. These African countries need cheap way to find water because they have no money, and their crops often die from no rain and no water. Bamboo pipes help poor farmers bring water to their thirsty fields without spending a lot of money.
How is bamboo like grass?

A．It grows quickly.	B．It’s wood.
C．It is easy to cut	D．It is very thin

Though you can see bamboo everywhere, it doesn’t grow ______.

A．in China	B．in Europe
C．on mountains	D．in Africa

Why is bamboo used by African poor farmers?

A．Because it is cheap.

B．Because it has different colours .

C．Because it is strong.

D．Because it has been used by Asians.

Bamboo pipes can ______.

A．make money	B．be trees
C．grow quickly	D．carry water

In a room at Texas Children Cancer Center in Houston, eight-year-old Simran Jatar lay in bed with a drip (点滴) above her to fight her bone cancer. Over her bald (秃的) head, she wore a pink hat that matched her clothes. But the third grader’s cheery dressing didn’t mask her pain and weary eyes.
Then a visitor showed up. “Do you want to write a song?” asked Anita Kruse, 49, rolling a cart equipped with an electronic keyboard, a microphone and speakers. Simran stared. “Have you ever written a poem?” Anita Kruse continued. “Well, yes,” Simran said.
Within minutes, Simran was reading her poem into the microphone. “Some bird soaring through the sky,” she said softly. “Imagination in its head…” Anita Kruse added piano music, a few warbling (鸣, 唱) birds, and finally the girl’s voice. Thirty minutes later, she presented Simran with a CD of her first recorded song.
That was the beginning of Anita Kruse’s project, Purple Songs Can Fly, one that has helped more than 125 young patients write and record songs. As a composer and pianist who had performed at the hospital, Kruse said that the idea of how she could help “came in one flash”.
The effect on the kids has been great. One teenage girl, curling (蜷缩) in pain in her wheelchair, stood unaided to dance to a hip-hop song she had written. A 12-year-old boy with Hodgkin’s disease who rarely spoke surprised his doctors with a song he called I Can Make It.
“My time with the kids is heartbreaking because of the severity of their illnesses,” says Anita Kruse. “But they also make you happy, when the children are smiling, excited to share their CD with their families.”
Simran is now an active sixth grader and cancer-free. From time to time, she and her mother listen to her song, Always Remembering, and they always remember the “really sweet and nice and loving” lady who gave them a shining moment in the dark hour.

A few years ago, in one experiment in behavioural psychology, Stanley Milgram of Yale University tested 40 subjects for their willingness to obey instructions given by a “leader” in a situation in which the subjects might feel a personal dislike of the actions they were called upon to perform. Specifically, Milgram told each volunteer “teacher-subject” that the experiment was in the noble cause of education, and was designed to test whether or not punishing pupils for their mistakes would have a positive effect on the pupils’ ability to learn.
The teacher-subjects were placed before a panel of thirty switches with labels ranging from “15 volts of electricity (slight shock)” to “450 volts (danger — severe shock)” in steps of 15 volts each. The teacher-subject was told that whenever the pupil gave the wrong answer to a question, a shock was to be administered. The supposed “pupil” was in reality an actor hired by Milgram to pretend to receive the shocks by giving out cries and screams. Milgram told the teacher-subject to ignore the reactions of the pupil, and to administer whatever level of shock was called for.
As the experiment unfolded, the “pupil” would deliberately give the wrong answers to questions, thereby bringing on various electrical punishments, even up to the danger level of 300 volts and beyond. Many of the teacher-subjects balked at administering the higher levels of punishment, and turned to Milgram. In these situations, Milgram calmly explained that the teacher-subject was to carry on with the experiment and that it was important for the sake of the experiment that the procedure be followed through to the end. What Milgram was trying to discover was the number of teacher-subjects who would be willing to administer the highest levels of shock, even in the face of strong personal and moral revulsion(反感) against the rules and conditions of the experiment.
Before carrying out the experiment, Milgram explained his idea to a group of 39 psychiatrists and asked them to predict the average percentage of people who would be willing to administer the highest shock level of 450 volts. The overwhelming consensus was that basically all the teacher-subjects would refuse to obey the experimenter. The psychiatrists felt that “most subjects would not go beyond 150 volts” and only a small percentage of about one in 1,000 would give the highest shock of 450 volts.
What were the actual results? Well, over 60 per cent of the teacher-subjects continued to obey Milgram up to the 450-volt limit! In repetitions of the experiment in other countries, the percentage was even higher, reaching 85 per cent in one country. How can we possibly account for this result?
One might firstly argue that there must be some sort of built-in animal aggression instinct(本能) that was activated by the experiment. A modem sociobiologist might even go so far as to claim that this aggressive instinct was of survival value to our ancestors in their struggle against the hardships of life on the plains and in the caves, finally finding its way into our genetic make-up.
Another explanation is to see the teacher-subjects’ actions as a result of the social context in which the experiment was carried out. As Milgram himself pointed out, “Most subjects in the experiment see their behaviour in a larger context that is good and useful to society — the pursuit of scientific troth. The psychological laboratory has a strong claim to legitimacy(合法性) and gains trust and confidence in those who perform there. An action such as shocking a victim, which in isolation(单独看来) appears evil, acquires a completely different meaning when placed in this setting”.
Here we have two different explanations. The problem for us is to sort out which of these two polar explanations is more reasonable. This is the problem of modern sociobiology — to discover how hard-wired genetic programming decides the interaction of animals and humans with their environment, that is, their behaviour. Put another way, sociobiology is concerned with explaining the biological basis of all behaviour.
Why did Milgram do the experiment?

A．To discover people’s willingness for orders from leaders.

B．To display the power of punishment on ability to learn.

C．To test people’s willingness to sacrifice for science.

Which of the following is right about the experiment?

A．The actor’s performance was vital to its success.

B．Its subjects were informed of its real purpose beforehand.

C．The electrical shock made the “pupil” give more wrong answers.
