閱讀短文，根據(jù)短文內(nèi)容回答問題。

We see them everywhere — on boxes of food, on packages and on CDs. They, of course, are bar codes. The invention of bar codes has changed the way we shop and how companies learn where their products are.

It was two university students from America, Bernard Silver and Norman Woodland, who first got theidea of bar codes. In 1948, they heard that the president of a food company was looking for a way to easily get information about what was being sold to customers. They tried to help by using a code system. They invented a large electronic reader to read the codes. However, computers couldn’t easily record the data that was read.

Then, in the 1960s, David Collins made important developments in bar codes. He developed a system for recognizing train carriages. In order to develop the recognition system for other kinds of businesses, Collins started his own company. In 1969, Collins’s company put a bar code reading system in a car factory, showing that bar codes could be useful.

Shortly after Collins started his company, an American electronic company called RCA also saw the potential (潛力) of bar codes to help businesses. RCA’s

system, which recorded how much of a product was sold, was not perfect. Since bar codes were not common, not all products had them and different companies used different codes. Then, Woodland helped develop the Universal Product Code (UPC), which gave every product a code that included information about the manufacturer and the kind of product being sold. This made bar codes much more practical.

In addition to shops, hospitals use bar codes to recognize patients by giving them cards with bar codes on them. Libraries use bar codes to record which books have been lent, and airports use them to find out where bags are going. Bar codes have made life much easier and simpler.

1.What changed the way we shop?

2.Who first got the idea of bar codes?

3.Why did Collins start his own company?

4.What do hospitals use bar codes to do?

5.What is the passage mainly about?

1.The invention of bar codes has changed the way we shop./The invention of bar codes./Bar codes. 2.It was two university students from America, Bernard Silver and Norman Woodland./Bernard Silver...

科目：初中英語 來源：牛津譯林版九年級下英語第二次模擬考試專題練習(xí)-閱讀表達(dá) 題型：多任務(wù)混合問題

Monarch butterflies from eastern Canada make the most amazing journey in the insect world. Each year, this butterfly travels about 3000 miles to its winter home in central Mexico(墨西哥). How can it fly so far and why does it make this long and dangerous trip. Scientists still don’t have an answer.

For many years, people in Mexico wondered where the orange-and-black butterflies came from every winter. Then, in 1937, a scientist started to follow and study the butterflies. For the next 20 years, he discovered that one butterfly started its journey in Canada. Four months later, it arrived in Mexico.

The length of the butterflies’ trip is only one part of the mystery. Another amazing thing is that the butterflies always return to the same area in central Mexico.

How do the butterflies find their way back to the same place. This is an interesting question because only every fourth generation (代) makes the trip south. In other words, the butterfly that travels to Mexico this year is the great-great-grandchild of the butterfly that traveled there last year.

Each year, four generations of a Monarch butterfly family are born. Each generations of the family has a very different life. The first generation is born in the south in late April. It slowly moves north, reproduces(繁衍) , and then die. Each of these generations of butterflies lives for generations are born, reproduces, and die. Each of these generations of butterflies lives for only two or five weeks. In the autumn, the fourth generation of butterflies is born. This generation has a much longer life. It lives for about eight months. This generation of butterflies makes the amazing journey back to the winter there, and in the spring they reproduce and then die. Their offspring will be the first generation of the next circle of life.

Today, people are still studying the Monarch butterfly. But they are not clear about everything.

1.How long did it take the scientist to find out the Monarch butterflies came from Canada?

_______________________________________________________________________.

2.Which generation of Monarch butterflies travel back to central Mexico?

3.Does each generation of the family have the same life?
