解答 41-45 KJIGH 46-50 AFDEC
41.K 考查名词.根据第一段的内容"the world's best weather forecasts"可知,话题是有关天气预报,所以"prediction"意思是"预测".
42.J考查动词.通过句子里的"through a chain of unstable features"可知"错误和不确定性"是成倍增长的.
43.I考查副词.对于"continent-size eddies"幅度比较大的旋风,普通预测不出来,只有卫星能预测.
44.G考查形容词.根据since ground stations and satellites cannot see everywhere推出因为地面气象站不能每个地方否预测到,所以原始数据都靠猜测.
45.H考查名词. all the way to the top of the atmosphere提示我们每隔一步间隔的距离就放置一个感应器.
46.A考查形容词.根据 后面的"readings of temperature,pressure,dampness"这一系列都是准确的数据.
47.F考查副词.此处需要用一个副词来修饰形容词,enormously powerful 意思是力量非常强大的.
48.D考查动词.calculate意思是计算,和句子里take并列谓语动词.
49.E考查动词.根据前句The computer will still be unable to predict 电脑不能预测一个月以外天气情况,所以会隐藏一些天气.
50.C考查形容词.from the average意思是从平均上来说,电脑有时候连细微的变化都会忽略.

Many people are not able to deal with stress because they simply don't know about the cause of their stress.Are your goals too high?Are you able to meet the demands of your family?Is everything between you and your friends all right?These are some of the many questions that you need to ask yourself.Even the simplest issues,such as traveling a great distance to your workplace,can cause a lot of stress.
Knowing the cause is very important and it is the first step in dealing with stress.
You also need to find the best way that suits you.Sometimes a bad memory or an incident that
happened in the past may worry you.You can always try meditation(沉思)to deal with such emotional
problems.The simplest of all relaxation techniques is to lie down on a bed and close your eyes.Try not to think of anything.
If you have a hobby,then dealing with stress becomes easier.A hobby not only helps you to get away from a stressful environment,but also gives you energy to deal with difficult situations.
More often than not you are unable to deal with a situation because you do not organize yourself.
Your actions are out of order because you are confused in your thoughts.Well,this may be because you are a little bit inexperienced.Try to think clearly.Write down the things that are troubling you or the things that you need to do.Make an efficient(有效的)plan to deal with them at home.A practical action plan solves almost all the problems that you can have.
