Why don't birds get lest on their long flights from one place to anotherScientists have puzzled over this question for many years. Now they are beginning to fill in the blanks. Not long ago. Experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly at night? Tests with artificial stars have proved that certain night flying birds are able to follow the stars in their long-distance flights.

A dove had spent its lifetime in a cage and never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird’s cage was placed under an artificial star-filled sky. The bird tried to fly in the same direction as that taken by his outdoor cousin. Any change in the position of the stars caused a change in the direction of his flight.

Scientists think that doves, when flying in daylight, use the sun for guidance. But the stars are apparently their principle means of navigation (领航). What do they do when the stars are hidden by cloudsApparently, they find their way by such land marks as mountain ranges, coastlines, and river courses. But when it's too dark to see these, the doves circle helplessly, unable to get their bearings (方位)

1. The reason why birds don’t get loot on their long flights________.

A. has been known to scientists for years

B. is known by everyone

C. still remains a question

D. has been discovered recently

2. The experiment with the dove indicated that________.

    A. a bird having spent its lifetime in a cage has to be thought to navigate

    B. a bird that has been caged will not fly long distances

    C. some birds seem to follow the stars when they fly at night

    D. birds can fly in the same direction as that taken by their cousins

3. Under artificial stars, the bird in the cage________.

    A. tried to fly in the same direction as birds not caged

    B. changed the direction when the position of the stars was changed

    C. would not fly well

    D. both A and B

4. In total darkness, doves________.

A. use landmarks                 B. circle helplessly

C. depend on the mountain ranges     D. fly in all directions

The recent death of the world's most famous sheepDolly the clone—has not dampened the enthusiasm (热情)of Chinese scientists, who are working hard to make more breakthroughs in clone technology.

“It is hard to say whether Dolly died at a relatively young age or died from defects (缺陷) in reproduction,” Du Miao, a researcher with the Biology and Growth Institute of the Chinese Academy of Sciences, told China Daily in Beijing yesterday. “But Dolly's case reminds us that both Chinese and foreign scientists should put more efforts into improving clone technology as well as disease treatment techniques in the field of cloning animals.” He said his institute, in co-operation (合作) with Yangzhou University in Eastern China's Jiangsu Province, had cloned more than 10 sheep since 1999 and the oldest is nearly five. They are all still alive.

Li Ning, deputy director of the National Key Laboratory of Agricultural and Biological Technology, who is also a professor with the Beijing-based China Agriculture University, said, “Clone technology is actually progressing well. Dolly is the first cloned sheep after all. Like driving cars, new drivers meet with accidents more easily, but the more you drive, the easier and safer you feel. In the future, the death rate of cloned animals will be reduced with technological developments.”

“Official reports show seven locally cloned sheep are still alive. Clone technology in China is gradually approaching (接近)a level of commercialization (商业化),” Li added. But Wang Yu, deputy director of the Biological Technology Centre under the Ministry of Science and Technology, said the commercialization of clone technology depends on market demand.

1. From Dolly's death, some of the Chinese scientists________.

    A. think it has dampened their enthusiasm

    B. believe it died from defects in reproduction

    C. think they should improve not only disease treatment techniques but also clone technology

    D. are satisfied with their successes in clone

2. Li Ning took driving cars for example to show________.

  A. the difficulty with clone technology

    B. anything is difficult in the beginning

    C. clone technology is difficult in the beginning and has a bright future

    D. clone technology will be more difficult in the future

3. According to Li Ning, the Chinese clone technology is________.

    A. behind some other countries

    B. progressing badly

    C. among the developed countries

    D. actually developing well

4. What is the best title for the passage?

    A. Learning Lessons from Dolly

    B. Chinese Scientists’ Clone Enthusiasm

    C. Clone Technology like Driving Cars

D. Chinese Clone Technology Well Developed

Then, when he was around 15 year old, he started to lift weights seriously for the purpose of body building. He also began competing in body building competitions in England at this time. When he was18, he won the Junior Mr. Europe competition. Then, he later won Mr. Olympia.

In 1968, when he was 21 years old, Mr. Schwarzenegger went to the United States. He continued to enter and win body building competitions. But he also started a company which helped build brick walls and building in order to earn extra money. He called his company Pumping Bricks.

Wood is wood?

Yes, but it’s not that simple. Each tree species (神类) grows in a certain way, and that affects (影响) the way its wood looks and performs. Foresters divide trees into two kinds: hardwood and softwood species.

Hardwood trees such as oaks (橡树) and maples (枫树 ) have wood with very short fibers. Paper made from these species is weaker than that made from softwood, but its surface is smoother, and therefore better to write and print on.

Softwood trees such as pines and spruces have wood with long fibers, and paper made from this type of woods is much stronger. This kind of paper is ideal for making products like shipping containers that require great strength. But the surface is rougher, and that’s not as good for writing, printing and many other uses.

Happily we can blend fibers from hardwood and softwood into a single paper, getting just the combination of strength, whiteness, writing surface and other characteristics that we want.

And that’s just what we do! Most of the paper you see today is made from both hardwoods and softwoods, a special blend for each purpose.

We make newsprint(新闻纸)to be opaque(不透明) —so you only see the newspaper's comics (连环画), not the stock market report on the other side!

We make grocery bag paper strong, tissue (纸巾) soft, fine writing paper smooth. Even within the same sort, there’s quite a range. Among printing papers, for example, compare the thin sheets of a Bible to the thick, tough pages of a kid’s picture book.

1. Which of the following are trees?

    A. Pines, oaks, fibers and maples.

    B. hardwood, oaks and maples.

    C. Pines and softwood

    D. Maples and oaks.

2. Which of the following is TRUE?

    A. Paper made from spruces is good to write on.

    B. Paper made from oaks is weaker, with smoother surface.

    C. Shopping bags are usually made of the paper from softwood trees, with short fibers.

    D. It is easy for us to make paper from both kinds of trees.

3. The underlined word “blend” perhaps means________.

    A. change         B. separate     C. mix          D. divide

4. The sentence “We make newsprint to be opaque” means_________.

    A. We make newsprint hard to see through.

    B. We make newsprint different from other printing papers.

    C. We make newspaper the way easy to understand.

    D. We make newsprint easy to read.

5. What haven’t we learned from the passage?

    A. Writing paper, as well as printing paper, is divided into many kinds.

    B. We can get a kind of paper made from both hardwood and softwood.

    C. According to the wood, we can divide trees into two kinds.

D. Today we use paper in many ways.

Some English words are made up of the same part and have different beginnings or different endings, such as import, export, repot and transport. All these words, you can see, have the same root “port” , which comes from the Latin word, meaning “to carry”  or “to move” from one place to another. And according to the bit at the beginning—which we call the prefix (前缀)—the meaning changes: “im” means “in” , so the word “import”  means “to carry in” , or “to bring into a country” ; “ex” means “out of” ,so the word “export” means “to carry out of a country” ; “re” means “back”, so the word “report” means “to tell somebody, to bring back information to somebody” ; “trans”  means “across” , so “transport”  means “to carry from one place to another” .

Let’s look at the following words: supporter, reporter, importer and exporter. You can see that in this case these words are nouns which are made up of the verbs plus the suffix (后缀 ) “er” , thus meaning a person who completes the “verb” . So supporter means somebody who supports something. A reporter is somebody who reports something. Importer is somebody who imports something and exporter is somebody who exports something, and so on.

Archimedes was a famous Greek mathematician and scientist. He was born around 287 B. C. and he died in 212 B. C.

Archimedes was most known for one specific idea that he came up with. “Archimedess Principle(定律)”states that a solid object which is immersed in a liquid is pushed up by a force which is equal to the weight of the water that the object moves. For example, if you put a piece of wood and a piece of gold of the same size in water, only the wood will float. Both the wood and gold move the same amount of water, but the wood weighs less than the water, while the gold weighs more.

It is believed the Archimedes discovered this principle when the king of Syracuse asked him to solve a problem. The king wanted to know whether his crown(王冠)was pure gold or a mixture of gold and silver. The king, of course, didnt want to melt his crown to find out. The idea came to Archimedes as he lowered himself into his bath. He noticed how the water spilled out of his tub. He decided to use the same idea for the crown. He knew that a gold crown immersed in water would weigh more than one made of silver. The experiment was done and the goldsmith(金匠)was found guilty(有罪的)of trying to cheat the king.

1. A good title for this section is__________.

A. Archimedes                       B. Archimedes Principle

C. A Gold and Silver Crown              D. The King of Syracuse

2. The word “immersed” in the second paragraph means__________.

A. raised            B. lifted            C. underwater        D. rose

3. From this section we may conclude(推断)that the king's crown__________.

A. moved more water than pure gold of the same weight

B. moved less water than pure gold of the same weight

C. moved more water than pure gold of the same size

D. moved less water than pure gold of the same size

4. The following sentences tell what happened many years ago. Which is the right order of the events(事件)?

a. Archimedes took a bath.

b. Archimedes discovered his principle.

c. The king of Syracuse asked him to solve a problem.

d. Archimedes did the experiment on the crown.
