Memory is said to be stored in the brain as a "memory trace (记忆痕) ". What makes up this trace is not known. Some scientists believe that certain chemical substances may carry certain memories. For example, one substance, when given to rats, causes them to fear the dark.
Other research into memory has to do with how the brain works. Psychologists use three means to find out bow a person remembers. For example, give a person a grocery list. Let the person memorize the list, then put it away. The most natural way to find out how much a person remembers of the grocery list is to ask what he or she remembers. This is called the method of recall. Another method is called recognition. Give the person another grocery list. Ask him or her to choose items on the first list from the items that are on only the second list. Often a person will be able to recognize things that he or she cannot recall. A third method of finding how much a person remembers is called relearning. Here the person is asked to read over the first list. The person will probably learn the list the second time faster than he did the first time. The difference in the time it takes to relearn the list is thought of as measure of how much a person has remembered.
One way of remembering something is to repeat it many times. Interest is very important. Boring lists of facts are much more difficult to remember than something that we understand and are interested in. Motivation, or wanting to do something, is also important. Motivation is linked with reward. For example, a hungry animal quickly learns how to do something if that action gets the animal food. In humans, wanting to learn is often motivation. The praise of a teacher or the knowledge that an answer is correct is rewarding.
We can learn from the 2nd paragraph that ______.
A.bad memories may cause rats to fear the dark
B.it is hard to tell what a memory trace consists of
C.chemical substances carry certain memories
D.memory is stored in the brain as a substance

Other reasons they take that first drink are to be rebellious (反抗的), for curiosity or "kicks" (刺激) or to escape an unpleasant environment. And young people drink and use drugs because alcohol (酒精) and drugs are at hand.
After first experimental use, young people continue to drink or use drugs because they believe these substances can relieve boredom, increase energy, decrease anxiety, solve problems, or help them socially. They may simply like the "high" they get in the early and middle stages of substance use. After continued use, they will drink or use drugs because they become physically and psychologically (心理地) addicted (上瘾的).
Now that we have admitted that we have to solve this problem. We must decide how to deal with this challenge. Winning this will take a great effort involving local, state, and national government. It will require the effort of schools, but it cannot be done by schools alone. It will take family and com munity involvement. Already a great amount of time, energy and expert knowledge has been directed toward dealing with it but the problem continues.
Which of the following is not mentioned as the reason of drinking and using drugs in the passage?
A.the selling of alcohol and drugs
B.pressure from their parents and relatives
C.curiosity
D.their eagerness to experience what is not permissible to them

根据下面内容,回答题:
Staff Sgt, Nicholas Lanier has entered what he calls the "vast unknown. "" A combat veteran and father to four daughters, he can"t remain in the military because of a serious back injury earned in Iraq.
But he can"t yet accept a civilian job because he doesn"t know when the military will discharge(使退伍) him. He has no clue how much the government will pay him in disability compensation related to his injury, so he can"t make a future budget. He just waits.
Thousands of troops are like Lanier: not fully fit to serve but in limbo (无着落) for about two years waiting to get discharged under a new system that was supposed to be more efficient than its predecessor. And the delays are not only affecting service members, but the military"s readiness as well. New troops can"t enlist until others are discharged.
The government determines the pay and benefits given to wounded, sick or injured troops for their military service. Under the old system, a medical board would determine their level of military compensation and the service member would be discharged. Then the veteran essentially would have to go through the process again with the Veterans Affairs Department to determine benefits.
Under the new system, which started in 2007 and will be completely rolled out at military bases nationwide by the end of September, the service member essentially goes through both disability evaluation systems at the same time before leaving the military. But the new, supposedly streamlined,system is still such a cumbersome process that it"s leaving many service members in limbo, they say.
Why can‘t Sgt. Lanier serve in the military anymore? 查看材料
A.Because of his injured back.
B.Because of his hand.
C.Because his vision has worsened.
D.Because he has a civilian job.
