Language learning begins with listening. Children are greatly different in the amount of listening they do before they start speaking, and later starters are often long listeners. Most children will “obey” spoken instructions some time before they can speak, though the word “obey” is hardly accurate as a description of the eager and delighted cooperation usually shown by the children. Before they can speak, many children will also ask questions by gesture and by making questioning noises.

Any attempt to study the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months one or two noises sort themselves as particularly expressive as delight, pain, friendliness, and so on. But since these can’t be said to show the baby’s intention to communicate, they can hardly be regarded as early forms of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new words to their store. This self-imitation(模仿) leads on to deliberate(有意的) imitation of sounds made or words spoken to them by other people. The problem then arises as to the point at which one can say that these imitations can be considered as speech.

It is a problem we need to get our teeth into. The meaning of a word depends on what a particular person means by it in a particular situation; and it is clear that what a child means by a word will change as he gains more experience of the world. Thus the use, at seven months, of “mama” as a greeting for his mother cannot be dismissed as a meaning-less sound simply because he also uses it at another time for his father, his dog, or anything else he likes. Playful and meaningless imitation of what other people say continues after the child has begun to speak for himself. I doubt, however, whether anything is gained when parents take advantage of this ability in an attempt to teach new sounds.

Scientists studying the impact of climate change on the Arctic need to consider ways to reduce their own carbon footprints(碳排放量), says Ryan Brook, a researcher who regularly flies north to study the health of caribous(驯鹿).He calls on scientists to show leadership by examining and sharing ways to reduce the impact of working in polar regions.
“The importance of the research is not at question here. It is important to our understanding of and adapting to climate change. But we need to think about better approaches,” says Brook.
“This is an issue for all scientists, though polar researchers often travel particularly long distances using commercial air travel. We also rely extensively on small aircraft, icebreakers, and snowmobiles, all of which produce large amounts of carbon.”
Brook studies the health of caribou herds in Nunavut and Northwest Territories. He works with northern wildlife managers. This work typically takes him north five or six times per year and when he calculated his own carbon footprint, he was not happy with the result.
“My research footprints are about the same as the annual footprints of an average Toronto resident. Basically, I have two footprints — my own personal life, which is moderate, and my research footprint.”
Climate scientists can rightly argue that Arctic research is a specialized field and the community of scientists who travel north is relatively small. Even if all scientists working in the north reduced their carbon emissions, it would not make a big impact on the global scale. For Brook, it’s the option that matters.
There are ways researchers can reduce the amount of carbon they use. Some helicopters use less fuel than others. Solar and wind power are alternatives to gas-fired generators. And while carbon offsets(抵消) don’t reduce the amount of carbon emitted, they are an easy first step.
“There aren’t necessarily any easy answers, but we need to start talking about it,” says Brook. “This is particularly important for the next generation of scientists being trained and I hope to see them become leaders in this issue.”
【小题1】What did Brook find when he calculated his own carbon footprints?

Hundreds of years ago, life was much harder than it is today. People didn’t have modern machines. There was no modern medicine, either.

Life today has brought new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and become angry easily. Air pollution is the most serious kind of pollution. It is bad for all living things in the world.

Many countries are making rules to fight pollution. We need to do many other things. We should put waste things in the dustbins instead of on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, less pollution will be made. Rules are not enough to solve the problems. Every person must help to fight pollution.

1.Hundreds of years ago, life was much harder than it is today because _____.

2.What is the most serious problem in today’s life?

3.Why do people speak louder now than before?

4.What does the writer ask readers to do?

5.From the passage, we know that _____.

A. the pollution is not serious     

B today people don’t talk in loud voice

C. we have to drink dirty water    

D. people are making rules to control pollution

This was no ordinary class. The students who came together were all science or engineering professors at Cornell University. They had interrupted their research to accept an invitation to take part in an unusual experiment: “an interesting week of poetry.” This class was part of a study to answer the questions: Why is science difficult for many non-science students? What can teachers learn about teaching if they take a class that is not in their field?

The students in the poetry class listened to lectures and took notes. They had reading tasks and had to write three short papers. All students noticed one thing – the importance of spoken words. In science and engineering classes, the instructors put tables and drawings on the blackboard. But in this poetry class, the instructors just talked. They didn’t write anything on the board.

The scientists and engineers noticed one similarity between science and poetry. In both subjects, students need to find layers (层次)　of meaning . Some layers are simple, clean, and on the surface; other layers are deeper and more difficult. This search for different levels of meaning doesn’t happen much in undergraduate(本科)　science classes, but it is important later, in graduate school. And it is always important in humanities(人文科学).

Both the poetry instructors and their students learned something about teaching from this experience. One poetry instructor, for example, now sees the importance of using informative as he teaches. Most of the scientists agreed on several points. First, humanities classes might help science students to see patterns and decide which information is important. Second, the poetry class was fun. One engineer decided, “We need to change the way we teach engineering to make to make it an enjoyable experience for students.”

But perhaps the most important result of the experience was this; All of the professors began to think about how they teach and how they cam teach better. 

What do we know about this unusual class?

A. The teachers did lots of writing on the board

B. The teacher were invited to attend several lectures.

C. The student were professors from a university

D. The students were studying science and humanities.

The experiment was designed to find out

Finding levels of meaning is            .

 A. important for graduate students in humanities
