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（進(jìn)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（顛倒）.
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 (隨意的).
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(變小) than it does to recover.
小題1: The underlined word “it” (Line 2) refers to “           ”
A．the activityB．the fish
C．the ruleD．the fisherman
小題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.
小題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.
小題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.

Can you imagine living in the desert for a whole year, watching the activities of a group of busy ants? Deborah Gordon did exactly that. She finally found out that there were four main groups of workers in the ant team: cleaners, haulers(搬運(yùn)工), gatherers and security (安全) ants. Each group did their own job to finish the task of the whole team.
Cleaner ants carried waste food from inside the nest to outside. Hauler ants walked on the top of the nest and cleared rubbish. Gatherer ants went out to find food for the whole team and security ants fought against anyone who wanted to hurt the members of the team.
While she was watching the ants in the desert, Deborah found that the most interesting part was watching the ants dealing with difficulties, such as fighting against other insects that wanted to destroy their nest, or a big fire. At those moments, they would all stop what they were doing and go to help security ants to protect their home.
What do we do when people around us meet difficulties? What have we done to turn our world into a better place? It’s time to think.

A 15-year-old student who invented a flashlight(手電筒) getting power from the holder's body heat is going home today from California with a big prize and a chance to do further research.
Ann Makosinski was the only Canadian among the four winners at Google's international science competition. Thousands of young scientists from around the world took part in the competition.
Winning the science and technology competition was "a surprise". Ann said, "I think it will have a great influence on my future."
Ann thanked her family for encouraging her interest in science and said that her first toy was a box of transistors(晶體管).
Ann's prize includes $ 25,000 and a "once in a-lifetime expericnce" from Google for her Hollow Flashlight, which has no moving parts or batteries.
The idea for the invention came from seeing unwanted batteries and her friend's experience. When Ann visited a friend in the Philippines, she saw the friend couldn't study when it became dark because there was no electricity or light. She saw the need for a flashlight that has no batteries - Hollow Flashlight.
In her project, Ann wrote "I made two flashlights that do not use any batteries or harmful materials. They do not create any noise and will always work. The flashlight needs at least a 5℃ temperature difference between the holder's body and the environment around to produce light."
A video of Ann explaining how she creatcd the flashlight has been watched more than 1.4 million times on the Internet.
Though Ann was successful, she has not made a decision about her career path. Ann hopes that she can find a way to join her love of film and science together.
The four winners were chosen from 15 final competitors from eight countries. The competition attracted thousands of students in 120 countries.

Decisions, decisions! Our lives are full of them, from the small ones to the life-changing. The right to choose is central to everyone. Yet sometimes we make bad decisions that leave us unhappy or full of regret. Can science help?
Most of us know little about the mental processes that lie behind our decisions. Luckily, what psychologists(心理學(xué)家)are finding may help us all make better choices. Here are some of their amazing discoveries to help you make up your mind.
Consider your emotions. You might think that emotions are the enemy of decision making, but in fact they are a part of it. Whenever you make up your mind, your brain’s emotional centre is active. University of Southern California scientist, Antonio Damasia, has studied people with damage to only the emotional parts of their brains , and found that they were unable to make basic choices about what to wear or eat. Damasia thinks this may be because our brains store emotional memories of past choice, which we use to help the present decision-making.
However, making choices under the influence of an emotion can greatly affect the result. Take anger, for example. A study by Nitika Garg of the University of Mississippi and other scientists found the angry shoppers were more likely to choose the first thing they were offered rather than considering other choices. It seems that anger can lead us to make quick decisions without much thinking.
All emotions affect our thinking and motivation（動(dòng)機(jī)），so it may be best to avoid making important decisions under their influence. Yet strangely there is one emotion that seems to help us make good choices. The American researchers found that sad people took time to consider the various choices on offer, and ended up making the best choices. In fact many studies show that people who feel unhappy have the most reasonable view of the world.
小題1:According to the text, what may help us make better decisions?
A．To think about happy times.
B．To make many decisions at a time.
C．To stop feeling regretful about the past.
D．To learn about the process of decision-making.
小題2:What does the underlined word “central” mean?
A．中心的B．中央的C．起決定作用的D．后悔的
小題3:Damasia’s study suggests that ________.
A．emotions are the enemy of decision making.
B．our brain has nothing to do with decision making.
C．people with physical damage find it hard to make up their minds.
D．our emotional memories of past choices can affect present decisions.
小題4:Why are angry shoppers more likely to choose the first thing they are offered?
A．They often forget their past choices.
B．They make decisions without much thinking.
C．They tend to save time when shopping.
D．They are too angry to bargain.
小題5:What do we learn from the text?
A．Emotions are a part of decision-making.
B．Sad people always make worse choices.
C．No emotion seems to help us make good choices.
D．Only sad feeling affect our thinking and motivation.
