　　Unit 3 A healthy life

　　6Ⅰ.阅读理解

　　(2015·山东省威海市二模)

　　Run, swim, lift weights, do yoga—do something, because it's good for you. Many studies tell us that regular exercise not only helps our bodies but improves memory, and eases anxiety. But what is happening to the mind during workout to create all these benefits?

　　A new study from Sweden suggests that a specific protein found in trained muscles might contribute to exercise's mental benefits. This protein, the researchers found, might help our bodies process molecules that, if out of balance, can stress us and contribute to depression(萎靡不振). The findings were published in the journal Cell.

　　To test this, the researchers kept attacking some mice with flashing lights, loud noises and interrupting their sleep for weeks. Predictably, this treatment makes the mice show signs and biochemical markers of depression.

　　But not all the mice showed those signs. One group, specially raised to have high levels of a protein called PGC1alpha1 (the one in trained muscles), did not show those depression signs. PGC1alpha1 increases production of an enzyme that breaks down a chemical called kynurenine. Kynurenine helps the body respond to an activated immune system(活性免疫系统), but it also plays a role in depression.

　　“Our original research assumption was that trained muscle would produce a substance(物质) with beneficial effects on the brain，” Jorge Ruas of the Karolinska Institute told Forbes.com. “We actually found the opposite: welltrained muscle produces an enzyme that removes harmful substances away from the body.”

　　This study was in mice, but it lines up nicely with all the other lines of evidence that exercise is good for mental health.

　　文章大意：体育锻炼有益身心健康，但是我们的大脑在锻炼过程中发生了什么变化从而有益于我们的身心的呢？本文给出了答案：锻炼的肌肉中产生了一种enzyme物质，它带走了我们身体里的有害物质。

　　1．According to the study, which of the following is bad for your mental health?

　　A．Protein.B．Molecule.

　　C．Enzyme.

　　D．Kynurenine.

　　答案：D　细节理解题。由第四段最后一句话“...but it also plays a role in depression.”可知，Kynurenine会造成我们心情萎靡不振。该题易误选B项，由第二段倒数第二句话“molecules that, if out of balance, can stress us and contribute to depression(萎靡不振)”可知，该物质本身无害，只有当它在身体内失衡时才有害，所以不选。

　　2．What conclusion have the researchers drawn from the study?

　　A．Unbalanced exercise leads you to depression.

　　B．Wellfed mice survive better though being illtreated.

　　C．Trained muscle produces a substance good for brain.

　　D．Regular exercise helps to clear rubbish away from body.

　　答案：D　细节理解题。由第五段最后一句话“...welltrained muscle produces an enzyme that removes harmful substances away from the body...”可知。

　　3．According to the last paragraph, the result of the study is ________.

　　A．reliable

　　B．doubtful

　　C．predictable

　　D．ambiguous

　　答案：A　推理判断题。该研究是在老鼠身上做的，但是它与其他研究非常吻合，所以该研究结果是可信的。

　　4．What's the main idea of the passage?

　　A．Why do you need regular exercise?

　　B．What matters most for your body?

　　C．How does exercise help your brain?

　　D．Why are mice chosen for the study?

　　答案：C　主旨大意题。由文章大意可知。

　　Ⅱ.七选五

　　根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余项。

　　(2015·北京市东城区第二学期综合练习一)

　　Anxiety is your mental watchman. Its fixed pattern is to search for what may be about to go wrong.It continually, and without your conscious permission, scans your life, even when you are asleep, in dreams and nightmares.__1__ When it finds one, it worries it.

　　Along with depression and anger, anxiety is one of the bad faces of worries. __2__ Controlled by anxiety, you will feel a lack of security and confidence. When anxiety is severe and pained, it can be a sign of a disorder, such as panic or terror.

　　Although anxiety seems to have a biological basis, it is habitforming for many of us. Some of our anxious feelings are in fact wasted energy. Anxiety has gotten out of hand when it is pointless and repeated. When you are faced with a problem at work, before taking a test, or making an important decision, you will feel anxious. When you are controlled by anxiety, you are unable to control your emotions(情感) to the point of it changing your daily routine and habits.__3__ Or you find you are usually anxious at work or around your family.

　　At times, you should listen to the message of your negative emotions, as uncomfortable as they may be, and change your outward life rather than your emotional life. __4__ If you are worried about the dangers of your brother's new hobby, sky diving, perhaps you ought to tell him so. Taking action may relieve your anxiety.__5__

　　By learning to stop always seeking guarantee, not only can you start to undo the automatic cycle of anxiety, but also you learn that you can manage just fine without the need for constant guarantee. This in turn creates a sense of selfconfidence and selfrespect, which is vital to overcome anxiety.

　　A．For these people, saying NO to others is often of much anxiety.

　　B．It reviews your work, your love, your play, until it finds an imperfection.

　　C．Comparing anxiety with depression helps to discuss possible cures for anxiety.

　　D．These three common emotions are considered the cause of most mental illnesses.

　　E．If that doesn't work, then it's time to deal with any automatic thoughts in yourself.

　　F．If you are anxious about the work, you might get to the office an hour earlier every day.

　　G．You find yourself waking up anxious, going through the day anxious and going to bed anxious.

　　文章大意：本文是说明文。该文章主要告诉我们如何摆脱焦虑这种情绪。

　　1．B　根据前文的go wrong和B项中的imperfection和下文的worries判断。故选B项。

　　2．D　根据前句的depression and anger, anxiety和D中的three common emotions。故选D。

　　3．G　根据前句unable to control your emotions(情感)和G中的anxious判断。故G正确。

　　4．F　根据前文的negative emotions, uncomfortable和change your outward life以及F中的anxious about the work, you might get to the office an hour earlier every day判断。故F正确。

　　(2015·开封市5月模拟)

　　Last week, when we learned the new word “slovenly”， we asked to make a sentence with it. I volunteered to do it by saying “My deskmate is a slovenly girl who clothes never fit her.” Hearing this, a whole class burst into laughter and my deskmate face turned red. After class, I learned up from the teacher that my deskmate would have dropped out of school if she hadn't been helped with others. My mindless words must have hurt him deeply. Not until then do I realize words could be powerfully in both positive and negative ways. We should avoid hurt others if our words are not encouraging.
