—Put these glasses away before they ________.

—OK. I’ll put them in the cupboard.

A. have broken      B. are breaking  C. get broken     D. will be broken

C


解析:

因they (these glasses) 是break的承受者,用被動語態;又因在時間狀語從句中用一般現在時代替一般將來時,所以用一般現在時的被動語態,此處由“get+過去分詞”構成被動語態。

閱讀下列短文,從每題所給的四個選項中選出最佳選項。

  Darwin was a great scientist.He studied living things in the world.

  He said,“There are thousands of different living things.But in the past,the number was smaller.In the far past,a still smaller number.And at the be-ginning,perhaps only one.”

  Darwin waited a long time before he put these things into a book.He always tried to add more and more facts;he wanted his ideas about evolution(進化)to be right.

  It took him many years to write the book.At the beginning,people bought every copy.However,men of churches fought against Darwin's ideas.His story of the world was different from theirs.So either Darwin or the men of the churches must be wrong.But the churches didn't bring any new facts,or better ideas.They only brought angry words.

  Later,Darwin wrote a book about the evolution of man.He said that man is also a kind of animal.And again,Darwin didn't just write down his own ideas,he filled his book with facts to support his theory.We know now that he was right.It's now widely believed that there have been mankind on our earth for more than a million years.We have found some of the palaeoanthropic(遠古人的)bone fossils(化石)and those of other living things millions of years ago.These bone fossils have told us about the evolution of living things.

  Like any other animal,man has slowly evoluted through time.But we can't find the bone of man like us from a few million years ago.The world's animals were different then.

  But the bones can take us backwards(向后)through time into the past.And

they can help us with our study of the evolution of life.

1.Darwin believed that ________.

[  ]

A.there were living things in the past

B.there would be a small number of living things in the future

C.the number of living things had always been growing

D.there were one thousand living things in the past

2.The men of the churches ________.

[  ]

A.had new facts

B.had better ideas

C.agreed with Darwin

D.were angry with Darwin's theory

3.There were ________in Darwin's book.

[  ]

A.only view points

B.only facts

C.both viewpoints and facts

D.angry words

4.The men's bone fossils are important because ________.

[  ]

A.they help us with the study of the evolution of life

B.they prove that everything Darwin said was true

C.they show what men looked like in the past

D.they tell us that there were men a few million years ago

In the 13th century, the famous Italian traveler, Marco Polo, traveled a long way to China. During his stay in China, he saw many wonderful things. One of the things he discovered was that the Chinese used paper money. In western countries, people didn’t use the paper money until 15th century. However, people in China began to use paper money in the 7th century.
A Chinese man called Cai Lun invented paper almost 2,000 years ago. He took the wood from trees and made it into paper. He then put these pieces of paper together and made them into a book.
Now paper still comes from trees. We use a lot of paper every day. If we keep on wasting so much paper, there will not be any trees left on the earth. If there are no trees, there will be no paper. Every day, people throw away about 2,800 tons of paper in our city. It takes 17 trees to make one ton of paper. This means that we are cutting nearly 48,000 trees every day. Since it takes more than 10 years for a tree to grow, we must start using less paper now.
So how can we save paper? We can use both sides of every piece of paper, especially when we are making notes. We can use cotton handkerchiefs and not paper ones. When we go shopping, we can use fewer paper bags. If the shop assistant gives us a paper bag, we can save it and reuse it later.
Everyone can help to save paper. If we all think carefully, we can help protect trees. But we should do it now, before it is too late.
【小題1】 When he was in China, Marco Polo ____________.

A.discovered Cai Lun invented paperB.learned to make paper
C.saw many wonderful thingsD.read a lot of books
【小題2】 Which of the following is not a way of saving paper?
A.To use both sides of every piece of paper
B.To use fewer paper bags when shopping
C.To use cotton handkerchiefs instead of paper ones
D.To grow more trees
【小題3】 Which of the following is not true?
A.If we keep on wasting paper, we will have no paper to use one day.
B.The Chinese used paper money much earlier than people in western countries.
C.About 48,000 trees can be used to make 2,800 tons of paper.
D.It is never too late to plant trees for paper.
【小題4】 Which of the following is the best title for the passage?
A.Saving PaperB.The History of Paper
C.Cotton Handkerchiefs Back AgainD.Cai Lun, the Inventor

B

A sign is another kind of language. Here are some of them that you see on the roads.

Number one is a sign with the number thirty on it. When drivers see this sign, they must not go at more than thirty kilometers an hour. We see this sign when we are getting near a town. Number two is a sign that we’re near a crossing. We must drive carefully. Number three is a sign that there is a bend in the road. Again, we must drive slowly and carefully. It is not safe to go round a bend very fast. Number four is a sign that there is another road coming in from the right. There is a junction at this place. Number five is a sign that there is a hill and number six is a sign that the road gets narrow. Drivers must go slowly and carefully. Number seven has the word “SCHOOL” on it. This is a sign that there is a school at the side of the street or the road. Perhaps there are children going to or leaving school. So drivers must look carefully and go slowly. Number eight is a sign with the letter “P” on it. The letter “P” means “Parking”. At some places, there’re the signs “No parking” or “No waiting”. If a driver leaves his car near one of these signs, a policeman may come and write down the number of his car.

61. At the places where you see Sign 1, ________.

A. you are already out of a town

B. you still have thirty kilometers to go

62. There stands Sign 2 near a place where________.

A. two roads cross            B. people can cross the road

C. the roads get narrow        D. there are no traffic lights

63. You have to drive not only slowly but also carefully when you find________.

A. each of the eight signs              B. either of Signs 2 and 3

C. all of Signs 3, 5, 6 and 7            D. any of Signs 3, 5, 6 and 7

64. A driver can leave his car________.

A. near Sign 8 at any time

B. near a sign with “No parking” on it

C. near a sign with “No waiting” if there’re no police there

D. near a sign with “P” on it in the daytime

65. People put these signs on the roads to________.

A. show drivers the way           B. stop cars going too fast

C. make driving even safer         D. learn another kind of language
