A

The weather is getting hotter. You are thirsty playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you are drinking. Something that looks cool may not be good for your health.

There are plenty of "energy drinks" on the market. Most of them have beautiful colors and cool names. The lists on them tell you they are helpful to your health. Sounds great!  

But after a careful check you may find that most energy drinks have lots of caffeine (咖啡因) in them. These drinks are especially aimed at young people, students, busy people and sports players. Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much.

Caffeine makes your heart beat fast. Because of this, the International Olympic Committee has limited( 限制) its use. Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea. Possible health dangers have something to do with energy drinks. Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.

1.Many people like drinking energy drinks because of the following EXCEPT that ________.

A.they have beautiful colors and cool names

试题分析:这篇文章讲的是当天气变热或者运动之后,人们往往喜欢喝一些能量饮料,但是这些饮料含有大量的咖啡因,对身体是很不健康的,所以作者建议大家要少喝这些饮料。

1.细节题。由第二段Most of them have beautiful colors and cool names. The lists on them tell you they are helpful to your health.大多数的能量饮料有着诱人的颜色和酷酷的名字。从饮料的标签可由看出这些饮料有益健康。由第三段Makers sometimes say their drinks make you better at sports and can keep you awake.制造生说他们的饮料能够使你更擅长体育而且能使你保持清醒。可知,以上就是大多数人选择能量饮料的原因。故本题选B

2.细节题。由第四段Possible health dangers have something to do with energy drinks.潜在的健康危害与能量饮料有关。故选D

3.推断题。第四段Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.一瓶能量饮料就能使你紧张,失眠。甚至导致心脏病。由此,可推断出科学家说对青少年应该是阻止他们喝含有大量咖啡因的饮料。故discouraged的意思应是阻止,可替换成stopped。故选B

4.推断题。从文章中我们可以了解到广告对于人们购买饮料有着很重要的作用。能量饮料对于青少年的学习没有帮助。运动员应该少喝能量饮料。These drinks are especially aimed at young people, students, busy people and sports players.这些饮料的目标人群是针对年轻人、学生、忙碌的人们和运动员。可知,B,C,D错误。故选A

5.主旨题。这篇文章主要是围绕能量饮料展开的,讲了能量饮料的成分,人们为什么爱喝能量饮料以及能量饮料对身体的危害。故可知,选项C最为合适。

考点:科普类议论文

点评:本文的思路清晰,结构明确。首先把握好作者的写作情感,表达对作者对运动后能量饮料并不赞同,因为有过多的咖啡因。对于细节题,学生在理解全文的基础上要对题目中关键字在文章中迅速定位,找到相对应的出处,答题比较备选答案的区别及和文章信息最相关的是哪个,即那个就为正确答案。

When we want to find out what the weather will be like tomorrow, we usually turn on the TV. But people also needed to forecast (predict) the weather before they had TV. How did they do it in the past? They’d find an outdoor space, look up, look around, and listen.

Look UP

Red sky at night, sailor’s delight!

Red sky in the morning, sailors take warning!

This weather poem was written a long time ago, but it still works today. Weather in many parts of the wold moves from west to east. Whatever weather is in the weat tonight will probably be with us tomorrow. So a red sky at night, as the sun is setting, usually means a sunny day for the next day.

Look Around

Animals, insects, and plants are natural weather forecasters.

   When a summer storm is coming , you may notice that dogs, cows and horses grow restless. Theses animals don’t have some mysterious sixth sense, but they do have super-sensitive hearing. Scientists think the animals can forecast thunderstorms (雷雨)because they can hear the sound waves(声波)made by them many miles away.

   When leaves show their undersides, be very certain, rain happens.

Listen

If you hear a cricket, it can tell you the exact temperature. Just count its chirps (啾啾声) for fourteen seconds and then add forty. This will give you the Fahrenheit temperature of the cricket within a very few degrees. Since crickets are cold-blooded, the temperature of the cricket is about the same as the air around it.

So learn to predict the weather the way people did in the past. Get outside, look up, look around, and listen. Soon you’ll be your very own weather forecaster.

64. Did people need to forecast the weather before they had TV?

65. What does a red sky at night mean for the next day?

66.Why can animals forecast thunderstorms?

67.How can we know the temperature from a cricket?

68. What does the passage mainly tell us?
