Fishing is a popular activity and every fisherman knows the rule: Keep the big ones, throw the smaller ones back. The idea behind Lt is simple - the larger fish are probably older. If you keep the smaller ones, they won’t be able to reproduce, and the fish population is in danger.
But fishing out the largest fish from a population has an unwanted effect: Over time, fewer adult fish get really big. If only the smaller fish reproduce(繁殖), then future generations become smaller. This is an example of evolution(进化) in action.
One scientist, Dr David Conover has spent the last decade studying the effects of the “keep the big ones” rule and if they can be reversed(颠倒).
To set up his experiment, Conover and his team caught hundreds of silverside fish and divided them into six groups. For two groups, Conover followed the “keep the large ones” rule and took out the biggest fish. For two other groups, he removed only the small fish.
For the last two groups, he removed fish at random (随意的).
After five years, he measured the fish in each group. In the two groups where the largest fish were regularly removed, the average fish size was smaller than the average size in the other groups. Here was evolution in action: If only small fish survive to reproduce, then future generations of fish will also tend to be small.
For the second five years of his experiment, Conover changed the rules and took fish randomly from each group. At the end of the experiment, he found that the fish that were in the “keep the large ones” group for the first five years had started to get larger again, although he calculated it would take at least 12 years for the fish in that group to return to their original size.
In other words, it takes less time to shrink(变小) than it does to recover.
小题1: The underlined word “it” (Line 2) refers to “           ”
A.the activityB.the fish
C.the ruleD.the fisherman
小题2:Why do many people follow the “keep the big ones, throw the small ones back” rule?
A.It helps to protect fish numbers.
B.It helps to protect fish size.
C.It is the custom in most countries.
D.They will be punished if they don’t.
小题3:What did Conover find after the first five years of his experiment?
A.The “keep the big ones” rule made no difference to fish size.
B.The “keep the big ones” rule made fish smaller on average.
C.The “keep the big ones” rule made the fish bigger on average.
D.The “keep the big ones” rule affected all fish populations in the same way.
小题4: What is the author’s intention in writing this article?
A.To encourage people to fish more carefully.
B.To urge governments to change the rules of fishing.
C.To describe the results of a scientific experiment.
D.To introduce the rules of fishing to readers.

We spent a few days in Paris last week. We visit the famous city quite regularly. After all, it only takes three hours from London to Pairs. It’s always a pleasure visiting places we really like, exploring areas we’ve never been.
The only unlucky thing this time was the weather. As soon as we got there the temperature reached almost 35 degrees C (which lasted until we left). It was so hot that Matthew just couldn’t stand it — for him, it wasn’t the most enjoyable trip. I felt sorry for him because every time we go there he has to put up with (忍受) my endless shopping spree (狂欢) …
Because of the heat, we ended up just having lots of ice-cream and drinks most of the time, although we managed to pay a few visits to the new Herme shop on rue de Vaugirard at least. It’s not as busy as the shop on rue Bonaparte so you can choose whatever you like without worrying about a queue behind you! I really enjoyed his bread this time as well as the cakes. And I must say that his Croissant aux Amandes and Bostock were simply the best I’ve ever had.

It is two months since MH730 first went missing in the early hours of March 8th, while flying from Kuala Lumpur to Beijing. Malaysia Airlines said it was terribly sorry that MH370 ended in the southern Indian Ocean. People are losing hope that the passengers on the      could return alive and realize they should know how to save themselves when accidents like this happen in the air.
  1985, an Australia professor, Ed Galea, has interviewed 2,000 survivors of 105 airplane accidents, searching for the keys to survival (n.幸存) and found out      golden rules after years of research.
First, make sure that the airline does not keep your family members too far away on the plane, if you are traveling in family group.     ? It’s natural that while feeling in danger, you’ll probably want to meet the family before you can calmly move out.
Second, how do you untie (解开) your seat belt on a plane? By lifting a latch.            you can’t untie your seat belt, you can hardly run away and your chances of survival will drop.
Third, the           to the exits (逃生口), the more likely you are to survive. Count exactly how many rows you are from the nearest two exits. Why two exits? Because this helps you find at least               even in the sudden dark during an accident.
Fourth, we would be safer if airline seats faced backward, according to Galea’s research. But the problem is that most of the passengers              traveling with their back facing the direction of travel.
Fifth, “Smoke is dangerous to your health. If you take in too much of it, your will die,” explains Galea. You must learn how to use a smoke mask. Without the knowledge of putting on a mask, you’ll              time trying to put it on—time that could be used to run away.
At last, listen to the flight attendants before flying and look      at everything shown on a video or a safety card. Always be prepared. Good luck to you.
