(黄冈市2013中考英语测试题)A
Big ocean fish hav ( http: / / www.21cnjy.com )e almost been endangered since the start of business fishing in the 1950s. The scientists found that the number of large fish has dropped by 90 percent in the past fifty years. The study took ten years. The researchers collected records from fishing businesses and governments around the world. The magazine Nature published (发表) the findings.
The scientists say the common way called long line（多钩长线） fishing is especially harmful to large fish. This way includes many fishing lines that are connected (连接) to one boat. If these lines are joined together, they can reach one hundred kilometers. They hold thousands of sharp metal hooks to catch fish. Long line fishing is especially common in the Japanese fishing industry. Records showed that Japanese boats used to catch about
ten fish for every one hundred hooks. The study says long line fishing boats now might catch one fish per hundred hooks.
The scientists say business fishing can destroy groups of fish much faster than in the past. The study suggests that large fish can disappear almost completely from new fishing areas within ten to fifteen years. Ocean life systems could be destroyed.
It's not the only w ( http: / / www.21cnjy.com )orry that the number of large fish is becoming smaller and smaller. What's worse, they are smaller in size than their ancestors (祖先).
1.The underlined word “hooks” in the second paragraph means ________.
A. 钩 B. 镰刀 C. 圈套 D.引诱手段
2. The number o ( http: / / www.21cnjy.com )f big ocean fish is becoming smaller and smaller because ________.
A. the oceans are polluted B. many ways of fishing go into practice
C. long line fishing is widely used in the Japanese fishing industry
D. the scientists and government pay little attention to them
3. According to the passage, how do you feel about business fishing
A. It should be encouraged B. It can balance ocean life systems.
C. It needn’t be ( http: / / www.21cnjy.com )cared about D. It may bring much harm to ocean fish
4. Where is the passage probably taken from
A. A story book B. A sports newspaper
C. A fashion magazine D. An environmental report
5. Which of the following can be the best title for the passage
A. Long line fishing B. Japanese fishing industry
C. Modern fishing ways D. Worrying situation of big ocean fish

（2012年河南省中考英语试题）One d ( http: / / www.21cnjy.com )ay a man found a cocoon (茧) of a butterfly in the forest. He sat there for several hours and watched the butterfly. Suddenly a small opening appeared, and the butterfly made its great effort to force its body through that little hole. Then it seemed to stop making any progress. It appeared as if it had gotten as far as it could and it could go no further.
So the man dec ( http: / / www.21cnjy.com )ided to help the butterfly. He cut off the remaining bit of the cocoon so that the butterfly could come our easily. But to his surprise, the butterfly got a heavy body and very small wings when it came out of the cocoon.
The man continued t ( http: / / www.21cnjy.com )o watch the butterfly because he expected that the body would grow smaller at any moment and the wings would become larger and be able to fly. But neither happened! In fact, the butterfly spent the rest of its life crawling (爬) around with a heavy body and small wings. It was never bale to fly.
The man was in his ( http: / / www.21cnjy.com )kindness, but he did not understand the nature rules. Before the butterfly came out of the cocoon, fluid (流体) from its body must be forced into its wings, and then it would be ready for flying. It must have a hard struggle (拼搏) to get through the small opening to get its freedom from the cocoon.
Sometimes struggles ( http: / / www.21cnjy.com )are exactly what we need in our life. If God allowed us to go through our life without any difficulties, it would make us fail. We would not be as strong as we could have been; we could never fly.
1. What was the butterfly doing at the beginning of the story？
A. It was trying to make a cocoon for itself.
B. It was struggling to get out of its cocoon.
C. It was flying among the trees in the forest.
D. It was crawling around quietly on the ground.
2. The man cut off the remaining bit of the cocoon ____.
A. to take the butterfly home
B. to help the butterfly come out easily
C. to kill the butterfly
D. to stop the butterfly growing bigger
3. What do you think of the man
A. Patient but cruel. B. Careful and wise.
C. Kind but unwise. D. Brave and funny.
4. What does the last paragraph (段落) tell us
A. Struggles are sometimes necessary in our life.
B. Nothing is difficult if we put our heart into it.
C. Every good deed will come back with good result.
D. The greatest happiness in the world is to help others.
5. What is the best title for the story
A. The Love for the Cocoon
B. The Joy of Helping Each Other
C. The Lesson of the Cocoon
D. The Expectation for the Butterfly
