In a university library, a student is writing an essay on his laptop. But that’s not all. He’s also reading instant messages online, listening to his music with headphones, and checking text messages on his cell phone. In today’s world, people use a wide variety of electronic media to multitask, doing several things at the same time. Neuroscientists are studying the brain to see what happens during multitasking and to see if multitasking affects the quality of what we do.
In a multitasking study conducted by French scientists Eienne Koechlin and Sylvain Charron, people were given one task requiring concentration. Brain images showed that both the left and right prefrontal cortex (前额叶皮质) were active as people worked. However, when the person is given a second task to do at the same time, the left prefrontal cortex look on task, and the right look the other. When doing two tasks, MRI (磁共振成像) images showed that the brain was rapidly switching between the first and the second task. The brain was not working on both tasks at the same time. It is concentrating on one task and then switching to the other.
In order to switch attention from one task to another, the brain must use its working memory. This is the brain’s ability to temporarily hold information while it does something else. When you multitask, the first task is stored in your working memory. Then your brain goes to the second task but when it returns to the first task, it must restart it, using working memory.
Although we think we are getting more done by multitasking, evidence shows that we do not. Researchers have found that people take longer to complete tasks and make more mistakes. When the French researchers expanded their experiment to include three tasks, surprisingly, the brain seemed to completely drop on task and only focus on two tasks. The French team concluded that the brain could not focus on more than two tasks at a time. Therefore, for a task that requires your concentration, it’s better to just focus on that one task until you are done.
1.Why does the author mention a student in paragraph 1?
A.To explain what happens during multitasking.
B.To serve an example of high-tech multitasking.
C.To show how to be skillful at high-tech multitasking.
D.To-present the applications of high-tech media.
2.What does the underlined “it”in paragraph 3 refer to?
A.The brain. B.The MRI image.
C.The first task. D.The second task .
3.What can we learn about multitasking?
A.Electronic media improve its quality.
B.Three tasks can be well managed at a time.
C.It can damage the brain’s working memory.
D.It may result in the loss of speed and accuracy.
4.What can be the best title for the passage?
A.How does the brain multitask?
B.Why do we need to multitask?
C.Multitasking: a hew discovery of neuroscience
D.Multitasking: a way to expand the brain' s function

Many scholarships require that you write an essay in order to be considered for the prize money. However, if you are the sort of person that has a headache whenever you have to complete a writing assignment, this may not be the best news. Luckily for you, there is no reason to fear the scholarship essay. The following tips could help you conquer this not-so-easy aspect of the scholarship application process.
You should always outline your essays. This does not just apply to the scholarship essays, either. An outline helps lend focus to your thoughts and helps you create a picture of the “whole” that the essay will become. Judges cannot to stand when your writing is loose, lacks coherence(连贯性)or when you fail to connect your main points together. They want to see that you can support your argument well with clear and brief examples and that these examples do, in fact, relate to the topic at hand.
If you have a choice in the topic you get to write about, always try to select something you are personally interested in. Don't write what you think the judges want to hear. This will only amount in an essay that reads like someone else’s, which is not a great way to make yourself stand out.
If you feel bored with the topic, then your essay will be boring as well. Make sure your idea follow a clear and a logical path. This means they are connected well and the transitions(过渡) easily flow from one idea to the next. Likewise, try to stay away from the obvious or the sad story. Yes, college will be a life-changing experience, but can you think of an interesting reason why this is so? And yes, it is terrible that you lost a family member at a young age, but what does it have to do with winning this scholarship? Judges can smell sad stories from a mile away, so only pull at the heartstrings(动人心弦) if you have a proper reason for doing so.
1.When writing a scholarship essay, an outline is necessary because it helps you_____.
A. focus on the details of the essay
B. think more about the scholarship
C. make a picture of the whole essay
D. support your argument well
2.Your essay will be appreciated by judges if it _______.
A. turns out to be loose
B. is short of coherence
C. is unable to connect to the main points
D. supports your argument with brief examples
3.What is the author’s opinion on choosing the topic for a scholarship essay?
A. The essay should include the obvious or the sad story.
B. You must keep your mind clear and logical.
C. You had better try to put an interesting story in it.
D. Try to say as much as you can about your family.
4.The intended readers of the passage are probably________.
A. college students B. judges in colleges
C. essay readers D. company leaders
