At first all films were in black and white, but in 1932 the first color film was made. It proved as unpopular as making films had done in the late 1920’s. It was not until 1938 that a full length color film was made, and the success of this film made producers(制片人) everywhere change from black and white to color. This first full-length color film was translated （翻译）into ten different languages and made Hollywood（好莱坞）the main center（ 中心）of film industry(电影业)

In the early days of the cinema, other countries had also film industries. Very good films were made in Sweden, Britain, Russia and France. However, because Holleywood had so much money to spend, it kept its position as the world’s most important film center. Film actors went to America because they knew they could get a lot of money for every film they made. In 1918 Charlie Chaplin （查理·卓别林）received $5 each day.

However, life was not always easy for the film actors. Newspapermen followed them everywhere, and after Charlie Chapine married for the fourth time he became so unpopular with the American public that he had to leave the country and live in Europe.

1.. Which of the following is correct?

2... The first full-length color film was made ___________

3.. Many film actors went to America because ___________

4... Life was sometimes difficult for actors because ______________

Can you imagine that several hundred years ago, tomatoes were seen as toxic food in Europe?

What made Europeans believe this was John Gerard’s publication of Herbal in 1597. Gerard wrote: “The leaves and stalks of the tomato plant are toxic.” Undoubtedly, Gerard’s opinion was based on a misunderstanding of tomatoes. But his opinion was widely spread in Britain and North America for over two hundred years.

In the late 1700s, a lot of Europeans held more fears for tomatoes. A nick name for the fruit was “poison apple” because it was believed that aristocrats(贵族) got sick and died after eating them. But the actual reason was the pewter plates they used. Since tomatoes are high in acidity, when placed on the plates, the lead(铅) in the plates would dissolve(溶解). This caused many deaths. Unluckily, no one knew this at that time. So the innocent tomatoes were picked as the killer.

Today, more than one and a half billion tons of tomatoes are produced every year around the world. Tomatoes are cooked in various ways. This healthy and tasty food finally wins its innocence(清白) back.

1.Which of the following can be the best title for this passage?

A. Europeans’ fears for tomatoes

B. History of tomato planting

C. Why do people eat so many tomatoes

D. How did the tomato prove its value

2.What does the underlined word “toxic” in paragraph 1 mean?

A. delicious　　　　 B. nutritious(有营养的)

C. poisonous　　　　 D. safe

3.When did people begin to eat tomatoes according to the text?

A. About 100 years ago.　　　 B. About 200 years ago.

C. About 300 years ago.　　　 D. About 400 years ago.

4.What’s the key point for the death of the aristocrats mentioned in the passage?

A. Tomatoes.　　　　 B. The pewter plate.

C. Serious illness. D. Chemical reaction.

Today's personal computers are very different from the huge machines that were born during World War II-and the difference isn't only in their size. By the 1970s, these early PCs could not perform many of the tasks that today's computers can. Users could only do mathematical calculations(数学计算) and play simple games. Today PCs are used in many different kinds of ways. At home and at work, we use our PCs to do almost everything. It is nearly impossible to imagine modern life without them.

The earliest computers were not "personal" in any way: They were large and expensive, and they required a team of engineers and other experts to keep them running. One of the first and most famous of these, the Electronic Numerical Integrator Analyzer and Computer (ENIAC),　 was built at the University of Pennsylvania. ENIAC cost ﹩500, 000, weighed 30 tons and took up nearly 2, 000 square feet of floor space.

ENIAC and other early computers proved that the machines were worth so much money, space and manpower they needed. For example, ENIAC could solve in 30 seconds a problem that could take a team of human "computers" 12 hours to complete. At the same time, new technologies were making it possible to build smaller computers.

But one of the most important of the inventions that make way for the PC revolution was the microprocessor(微处理器). Microprocessors were the size of a nail. They could run the computer's programs, remember information and manage data(数据) all by themselves.

These new ideas made it cheaper and easier to produce computers than ever before. As a result, the smaller, cheaper "microcomputer"-soon known as the "personal computer"-was born. Today, portable computers, smart phones and ipads allow us to have a PC with us wherever we go.

1.What's mainly talked about in the first paragraph? ______

A.An even more relaxing lifestyle without PCs.

B.PCs can be made full use of to do everything.

C.Differences between modern and early PCs.

D.The difficult situation of PCs being born.

2.What do we know about the earliest computers? ______

A.It was easy to control them. B.They took up too much room.

C.Nobody could afford one. D.They were built by universities.

3.Why does the writer take ENIAC for example? ______

A.To predict high technology will make computers smaller.

B.To show computers are really smarter than human beings.

C.To explain why computers could deal with any problem.

D.To prove spending money on early computers was meaningful.

4.Which of the following makes the biggest contribution to microcomputers? ______

A.Microprocessors. B.Programs. C.Money. D.Imagination.
