They say it's boring. Why do they say this? First, some math problems are so hard for them. They spend a lot of time on them, but they can't work them out, so they lost heart . Second, they are afraid( ) to ask their teachers for help. They think the teachers will laugh at them. Third, they think math class is very tiring because they need to use their brain to find out the answers all the time. How can you do well in math? Here is some advice from a math teacher: 1. Listen to the teacher carefully in class and do some extra exercises after class. 2. Ask the teacher for help if you don't understand anything. Don't be afraid. 3. Don't forget to go over your old lessons. If you do these things, you will find it much easier to do better in math. Question: If you want to do better in math, you should NOT _ . Options: A: listen to the teachers carefully B: ask the teacher for help C: go over your old lessons D: lose interest in studying math

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 , then future generations become smaller. This is an example of evolution 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 . 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 . 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 than it does to recover. Question: What is the author's intention in writing this article? Options: 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.
