Standing too close to watch TV          your eyesight.
A．a(chǎn)ffectsB．effectC．a(chǎn)ffectD．effects
A

試題分析：句意：站的離電視太近會(huì)影響你的視力。Affect是動(dòng)詞，effect是名詞，所以排除BD，主語(yǔ)是動(dòng)名詞Standing too close to watch TV，所以謂語(yǔ)用單數(shù)，所以選A。

根據(jù)短文內(nèi)容，從短文后的七個(gè)選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。
Stage Fright
Imagine that you are an actor performing in a play for the first time. You have learned all your lines and you know where to walk on stage. Waiting behind the closed curtain, you can hear the audience whispering and taking their seats.
Then your big moment arrives! The curtain goes up, and the crowd falls silent. All you can see is the spotlight shining down on you.     小題1:   The inside of your mouth is dry, and your hands are wet.
If you have experienced a moment like this, you know all too well what it means to have stage fright. It is one of the most common types of fear and tends to strike people when they find themselves at the center of attention.     小題2:   People experience this fear when playing sports, giving a presentation, or even speaking in class. A person who suffers from stage fright may get sweaty hands, a dry mouth, a tight throat, or shaky knees. Stage fright is actually a form of panic, and these feelings are very real.
   小題3:   The experience differs from person to person, but the same chemical process occurs in each of us. In reaction to anxiety, our bodies produce a chemical that prepares us to either fight or run away quickly. Scientists refer to this as our bodies' "fight or flight" reaction. As a result, we feel great energy that makes our hands sweat, our hearts race, and our knees shake.
    小題4:   Practicing your performance and following some simple tips can help calm nerves and manage the feelings caused by anxiety. First, dress comfortably and appropriately. Second, before the performance, take deep breaths and stretch to help relax your body. Third, stay away from drinks that contain caffeine.     小題5:   Instead, try a banana! Some doctors believe that eating a banana can help calm your heart and the rest of your body. Finally, when you look into a crowd, try to focus on particular people instead of the whole group. These tips have helped many people learn to deal with their fears.
A．These might make your heart race even faster.
B．You don't have to be onstage to get stage fright.
C．Stage fright is part of the body's reaction to stress.
D．You try to speak your lines, but nothing seems to come out.
E. With practice, we can learn how to relax while playing sports.
F. The good news about stage fright is that here are ways to deal with it.
G. However, there is a time when stage fright prevents you from stepping onstage.

根據(jù)短文內(nèi)容，從下框的A—F選項(xiàng)中選出能概括每一段主題的最佳選項(xiàng)。 選項(xiàng)中有一項(xiàng)為多余選項(xiàng)。 （說(shuō)明：E涂AB；F涂AC）

E. Give to get.

Five Secrets of High-Energy People
小題1:Very little that’s new occurs in our lives. The impact of this sameness on our emotional energy is gradual, but huge: It’s like a tire with a slow leak(漏). You don’t notice it at first, but eventually you’ll get a flat. Here’s a challenge: If it’s something you wouldn’t ordinarily do, do it. Try a dish you’ve never eaten. Listen to music you’d ordinarily tune out. You’ll discover these small things add to your emotional energy.
小題2:The first step in solving this meaning shortage is to figure out what you really care about, and then do something about it. A case in point is Ivy, 57, a pioneer in investment banking. “I mistakenly believed that all the money I made would mean something,” she says. “But I feel lost, like a 22-year-old wondering what to do with her life.” Ivy’s solution? She started a program that shows Wall Streeters how to donate time and money to poor children. In the process, Ivy filled her life with meaning.
小題3:Most of us grown-ups live a dull life. High-energy people have the same day-to-day work as the rest of us, but they manage to find something enjoyable in every situation. A real estate broker I know keeps herself amused on the job by mentally redecorating the houses she shows to clients. “I love imagining what even the most run-down house could look like with a little tender loving care,” she says. “It’s a challenge—and the least desirable properties are usually the most fun.”
小題4:Everyone’s past is filled with regrets that still cause pain. But from an emotional energy point of view, they are dead weights that keep us from moving forward. While they can’t merely be willed away, I do recommend you remind yourself that whatever happened is in the past, and nothing can change that. Holding on to the memory only allows the damage to continue into the present.
小題5:Emotional energy has a kind of magical quality; the more you give, the more you get back. This is the difference between emotional and physical energy. With the latter, you have to get it to be able to give it. With the former, however, you get it by giving it. After all, if it’s true that what goes around comes around, why not make sure that what’s circulating around you is the good stuff?
