3.Eye strain is a very common problem.Whether it is from working on a computer,watching TV,driving or any number of other activities,your eyes can become tired and lose focus.(36)G With that in mind,here are 4simple tips to help prevent eye strain.
1.Take breaks.
The best way to prevent eye strain is using them not too much.Your eyes use more than one set of muscle.That means you can relax one set while using another.(37)D If you are at your computer,look out the window for a minute.If you are driving,check your speedometer every so often.
2.Reduce glare.
Reducing glare will certainly reduced the strain on your eyes.Use non-reflective interfaces(界面) whenever possible.(38)F When you have to use a screen make sure is at a 90degree angle from any direct light source.
3.Adjust contrast.
Ensure there is good contrast with what you are looking at.More contrast makes edges easier to recognize so the eyes don't have to focus as much.(39)EKeep overall lighting levels at a moderate level so there is good contrast around you but glare does not become a problem.
4.(40)A
Eye stain is actually the strain of the muscles controlling the eyes.Strengthening these muscles with a series of eye exercises will prevent eye strain effectively.

A.Strengthen your eyes.
B.Build up the muscles by sleeping.
C.Sunlight makes things easier to see.
D.Change your focus from near to far on a regular basis.
E.But too much contrast with the surrounding area will cause strain.
F.For example,reading from paper instead of a computer screen.
G.Serious eye strain can cause a number of other problems such as near-sightedness.

分析 本文就如何解决视觉疲劳提出几点建议:1.注意休息,不要用眼太多; 2.减少眩光; 3.调整对比度;
4.锻炼你的眼睛.

解答 36.G.考查对上下文语境的理解.空前一句Whether it is from working on a computer,watching TV,driving or any number of other activities,your eyes can become tired and lose focus的意思是:无论是从工作在一台电脑、看电视、开车或任意数量的其他活动,所以这里严重的视神经疲劳会导致一系列其他的问题如近视;故选G.
37.D.考查对上下文语境的理解.空后的If you are at your computer,look out the window for a minute意思是:如果您在您的计算机,往窗外看了一会儿.如果你在开车,经常检查你的速度表.所以这里改变你的焦点从近到远交替;故选D.
38.F.考查对上下文语境的理解.空前一句Use non-reflective interfaces(界面) whenever possible的意思是:尽可能使用非反射界面.空后一句When you have to use a screen make sure is at a 90degree angle from any direct light source的意思是:读的时候要尽量与界面保持90°角.所以这里例如,读纸质的而不是从电脑屏幕上读;故选F.
39.E.考查对上下文语境的理解.空后一句Keep overall lighting levels at a moderate level so there is good contrast around you but glare does not become a problem的意思是:保持周围的照明.所以这里与周边环境对比太大会导致紧张;故选E.
40.A.考查对上下文语境的理解.根据本段中的"Strengthening these muscles with a series of eye exercises will prevent eye strain effectively",可知你需要加强眼睛的锻炼;故选A.

点评 考察学生的推理判断能力和联系上下文的能力,在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.此类的填空题一定要联系上下文,根据上下文的内容加上自己的理解,再作出正确的判断.

8.Smiling is a great way to make yourself stand out while helping your body to function better.Smile to improve your health,your stress level,and your attractiveness.
(36)B
We are drawn to people who smile.There is an attraction factor.We want to know a smiling person and figure out what is so good because anxieties can push people away,but a smile draws them in.

Next time you are feeling down,try putting on a smile.(37)FSmiling can trick the body into helping you change your mood.

Smiling lowers your blood pressure.
When you smile,there is a measurable reduction in your blood pressure.Give it a try if you have a blood pressure monitor (血压计) at home.Sit for a few minutes and take a reading.Then smile for a minute and read it again while still smiling.(39)C
Smiling lifts the face and makes you look younger.
The muscles we use to smile lift the face,making a person appear younger.Don't go for a face lift,just try smiling your way through the day---you'll look younger and feel better.
(40)A
Try this test:Smile.Now try to think of something negative without losing the smile.It's hard.When we smile,our body is sending the rest of us a message that"Life is good!"

12.Anyone who has ever tried to stop smoking knows how difficult it is to quit.There is no lack of information about how unhealthy smoking is for you-not to mention the unpleasant smell.So why would teens ever begin to smoke?
(31)C Research shows that the majority of smokers lit up their first cigarette in their early or mid-teens,precisely at a time when children are beginning to establish their own identity apart from their parents.Smoking can be an act of rebellion(反抗) against parents or authority figures,as well as a way to fit in with others and feel accepted.
Here are some things that parents can do to help a child stay smoke-free.
Start talking to your teen about how bad smoking is for him early,well before his teens.Keep talking,too. (32)F
(33)DFor example,smoking makes your hair and clothing smell bad,stains the teeth,and reduces your lung power to play sports.
(34)BTalk about the addictive power of smoking and tell him while those few cigarettes are his choice,the addiction that occurs shortly afterwards makes him powerless to decide whether or not he wants to light up.
Work on self-esteem(自尊) and self-confident with your teen.Much of the attraction of smoking is to gain acceptance. (35)E

A.Young teens live in the moment,too.
B.Play on your child's desire to make his own choices.
C.The answer lies in the develop-mental stage of your teens.
D.Give your child the facts,but focus on the things he can relate to.
E.Help your teen to feel good about himself without having to smoke.
F.One discussion will not be enough to help your child not to smoke.
G.They won't be aware of how powerful addictive smoking is in a very short time.
