Human beings have used tools for a very long time. In some parts of the world you can still find tools that people used more than two million years ago. They made these tools by hitting one stone against another. In this way, they broke off pieces from one of the stones. These chips of stone were usually sharp on one side. People used them for cutting meat and skin from dead animals, and also for making other tools out of wood. Human beings needed to use tools because they did not have sharp teeth like other meat eating animals, such as lions and tigers. Tools helped people to get food more easily.

Working with tools also helped to develop human intelligence. The human brain grew bigger, and human beings began to invent more and more tools and machines. The stone chip was one of the first tools that people used, and perhaps it is the most important. Some scientists say that it was the key to success of mankind.

Since 1960 a new kind of tool has appeared. This is the silicon chip -- a little chip of silicon crystal. It is smaller than a finger nail, but it can store more than a million "bits" of information. It is an electronic brain. Every year these chips get cleverer, but their size gets smaller, and their cost gets less. They are used in watches, calculators and intelligent machines that we can use in many ways. In the future we will not need to work with tools in the old way. Machines will do everything for us. They will even talk and play games with us. People will have plenty of spare time. But what will they do with it?

Human beings used stone chips for more than two million years, but human life changed very little in that time. We have used silicon chips for only a few years, but life is changing faster every day. What will life be like twenty years from now? What will the world be like two million years

With around 40,000 students, the Politecnico di Milano is the largest and most technical university in Italy, offering undergraduate, graduate and other courses in engineering, architecture and design. Founded in 1863, just two years after Italy was united, Milan Polytechnic is international famous. Many of its graduates now work in big companies abroad like M.I.T., Caltech and Oxbridge.

Yet the Politechnic has a problem. As you know, here in Italy people speak Italian. Beautiful though the language may be, it is not a good choice for engineers when they’re building a way in Norway or designing a bridge in Vietnam. For better or worse, the global tongue of engineers is English. Hoping to attract more international students, the Politechnic decided to run its doctor’s courses in English only. Over 100 teachers went to court to block the plan, referring to a 1933 law that makes Italian the official language. For some teachers, all that matters is that they don’t feel comfortable teaching in English. In 2013, the court said they were right. Teaching English was out.

But there was more to come. They then went on a nationwide campaign against their university’s decision. Unwisely, the defenders of the Italian language backed them, saying, “we note with regret and concern the ignorance and abandonment(放弃) of Italian in the university education.”

The leaders at the Politechnic refused to be frightened, and asked for the ruling. Last month the Council of State said, “Art and science are free, and teaching them is free.” The question is whether teaching in English prevents students acquiring knowledge. But one could put it differently, and ask whether universities should be free to teach in whatever way they think best serves their students.

Interestingly, the people one might expect to be most against English-only teaching, the students themselves, have taken it easy. The president, Giovanni Azzone, told me: “Students write to me about everything from the lack of parking spaces to washrooms that don’t work. Not one has ever complained about the courses in English.”

1.The main idea of the passage is that the Politechnic decision to run its doctor’s courses in English only ________.

A. attracts more international students

B. sends more students to work abroad

C. makes some teachers out of work

D. meets with different responses

2.Which statement is NOT the reason why the Politechnic decided to use only English in class?

A. Many graduates work abroad.

B. Italian is widely used.

C. English is the global language.

D. The Politechnic is an international university.

3.Those who agree with the new change in the Politechnic are ________.

A. the Politechnic leaders B. over 100 teachers

C. the Council of State D. the defenders of Italian

4.The students’ attitude towards English-only teaching in doctor’s courses is _________.

A. indifferent(漠然的) B. disapproving

C. skeptical D. approving

Snow is a subject of great interest to weather experts . 1. . One reason is that heavy amounts of snow fall in surprisingly small areas . Another reason is that a small change in temperature can mean the difference between snow and rain .

Just what is snow , anyway ? Snow is a form of frozen water . 2. . These crystals grow from water droplets in cold clouds . They usually grow around dust particles(颗粒). All snow crystals have six sides , but they grow in different shapes . The shape depends mainly on the temperature and water levels in the air .

3. . About two and one-half centimeters of rain has as much water as 15 centimeters of wet snow . About 76 centimeters of dry snow equals the water in two and one-half centimeters of rain .

Snowfall helps to protect plants and some wild animals from winter weather . Fresh snow is made largely of air trapped among the snow crystals . 4. .

Snow can also influence the movement of sound waves . When there is fresh , soft snow on the ground , the surface of the snow absorbs , or takes in , sound waves . 5. . Then , the snow’s surface will help to send back sound waves . Under these conditions , sounds may seem clearer and may travel farther .

When I got the driving license last summer, Mom and I took our first trip around an empty parking lot. Then I found that my mother was not the best teacher for me. It wasn't that she shouted, or told me that I was doing poorly. As you can imagine, my mother's "helpful instructions" only managed to make me more nervous.

Since I could no longer practice with her, the job was placed in the hands of my father. The idea of learning from Dad was not one that thrilled me. I loved him dearly, but I just did not see Dad as someone I could be comfortable learning from. He almost never talked. We shared a typical father-daughter relationship. He'd ask how school was, and I'd say it was fine. Unfortunately, that was the most of our conversations. Spending hours alone with someone who might as well have been a stranger really scared me.

As we got into the car that first time, I was not surprised at what happened. Dad and I drove around, saying almost nothing, aside from a few instructions on how to turn. As my lessons went on, however, things began to change. Dad would turn the radio up so I could fully appreciate his favorite Stones music. And he actually began talking. I was soon hearing about past failed dates, "basic body" gym class, and other tales from his past, including some of his first meeting with Mom.

Dad’s sudden chattiness was shocking until I thought about why he was telling me so much in the car. In all the years that I had wondered why my father never spoke that much, I had never stopped to consider that it was because I had never bothered to listen. Homework, friends, and even TV had all called me away from him, and, consequently, I never thought my quiet father had anything to say.

Since I began driving with him, my driving skill has greatly increased. More important, though, is that my knowledge of who my father is has also increased. Just living with him wasn't enough—it took driving with him for me to get to know someone who was a mystery.

A. she couldn't talk with her mother

B. her mother made her nervous

C. her father wanted to teach her

D. she didn't trust her mother

C. satisfied D. uneasy

3.What surprised the author when the driving lessons went on?

A. Her Dad was a chatty person.

B. Her Dad was the best teacher.

C. Her Dad liked modern music.

D. Her Dad told her his sad stories.

4.With her story "Car Talk", the author indicates that .

A. fathers love their daughters dearly

B. family members need real communication

C. mothers are less patient than fathers
