Millions of years ago dinosaurs (恐龙)lived on the earth. In the days of dinosaurs the whole earth was warm and wet. There were green forests and they could find enough to eat. Later, parts of the earth became cold and dry, and the forests there died. Then dinosaurs could not find enough to eat. This must be one reason why dinosaurs died out.

We can guess another reason. New kinds of animals came on the earth. Some had big brains and were fast and strong. They could kill dinosaurs.

There may be other reasons that we don’t know about yet. Scientists are trying to make more discoveries about dinosaurs.

Dinosaurs were of many sizes and shapes(形状)。Some were as small as chickens, while some were about 90 feet long.

There were also terrible fights between dinosaurs. They might have happened more than 100 million years ago. Though there was no man to see any of the fights, we can be told by the animal’s footprints(足迹)that fight did take place.

1．According to the passage, dinosaurs did exist (存在) only　　 on the earth.

     We are going to describe one way to build a rooftop garden that does not even require
soil. Four things are needed for a small rooftop garden. One thing is a roof that can support
the weight. Another is grass cutting. The third thing is a sheet of plastic in which to spread
the cut grass. And the last thing is a box about eight centimeters deep and made out of four
pieces of wood.
     Once you are sure the roof is good, cut and collect some grass. Then lay down the
plastic where the garden box will go. The four-sided box can be as long and as wide as
needed. Place the box on top of the sheet of plastic. Then fill it with the cut grass. Next,
add water and walk on the cuttings to press them down.
     After about three weeks, the rooftop garden is ready for planting. Put the seeds directly
into the wet grass cuttings. This garden is a good place to grow peas, tomatoes, beans, onions
and lettuce. If the box is deep enough, potatoes and carrots will also grow.
     It is important to keep the grass wet until the plants begin to grow. When the plants are
growing, they will need watering every day, unless there is rain. And they will need some liquid
fertilizer. Also, seeds and new plants must be protected from insects and birds. Rooftop
gardens are increasingly popular, and not just to grow vegetables. They keep buildings cooler
in the sun, so they save energy. They can also extend the useful life of a roof.
     Rooftop gardens also reduce the runoff of storm water and help clean the air. Plus the
add beauty, and give birds and insects in the city a nice place to live.

The building of a rooftop vegetable garden

Things needed	1._______	Requirements

We live in a digital world now, and a student's technology needs have changed. For the early years, say when you are in primary school, you can get by with no technology at all. Even if you have a computer, it's a good idea to get children familiar with libraries. At this age, trips to the library are like family outings.

As you get closer to middle school, a computer with Internet access becomes more of a necessity. Teachers will often give assignments that require a student to use the Internet for research. After a computer, technology choices for students become more difficult to make – especially when it comes to cell-phones. Kids will beg their parents for a cell-phone, especially in middle school. For many parents, it's a safety issue: They want to know that their kids can reach them quickly if necessary. For teachers, cell phones can be used to record lessons when students are absent. But many teachers dislike cell-phones. Some kids send messages or have talks in the class. Sending messages also raises the problem of cheating on exams. More and more schools are now forbidding the use of cell-phones.

Many kids see iPods as necessary things to have. iPods are great for music, but do they do anything good for your children’s education? Maybe they do. That’s the opinion of Doug Johnson, an educator for 30 years. Johnson says that educators should accept all new forms of technology in the classroom, including iPods. “Some do more with their cell- phones than we can do with our laptops,” he jokes. “I don’t think we should be afraid. The truth is that it’s easier to change the way we teach than to change the technology habits of an entire generation.”

1. According to author, primary school children should___.

A. use the computer and the Internet regularly B. ask their parents to buy them cell-phones

C. buy iPods to listen to music D. go to libraries to read more books

2. Why do parents agree to buy their children cell-phones?

A. They want their children to be cool. B. They think cell-phones be helpful to their study.

C. They want to keep in touch with their children.

D. They want their children to keep up to date.

3. The following are all reasons why many teachers dislike cell-phones EXCEPT ____.

A. cell-phones can be used to cheat on exams

B. schoolchildren will send messages during class

C. cell-phones can be used to record lessons

D. schoolchildren might talk on them during class

4. What does the underlined word “that” refers to?

A. iPods can be used to listen to music. B. iPods can be helpful for children’s education.

C. iPods can be used to play games. D. iPods are necessary for children’s lives.

5. We can infer from what Doug Johnson said that _____.

A. cell-phones are not useful to students B. teachers should let students use cell-phones

C. it’s better for teachers to change their teaching methods

D. schoolchildren should follow the trends(潮流) of fashion
