6．There are students on the playground．（　　）

A．

hundred

B．

hundreds of

C．

hundred of

D．

two hundreds

分析操场上有数百名学生．

解答答案：B
hundred的用法：基数词+hundred+名词复数形式表示"几百…"表确数；hundreds of+名词复数表示"数百的…成百上千的…"，表约数，根据该词的用法，对照选项可知hundred以复数形式出现后面跟of短语，故填"hundreds of"，表示约数，故选B

点评记住基数词+hundred表示"几百…"表确数和hundreds of表示"数百的…成百上千的…"，表约数，是做题的关键．与之用法相同的还有thousand、million、billion．掌握这几个词的用法规律：在thousand、hundred、billion，million前有具体数字时，它们不加s，也不带of，表确数，这些词的复数形式后面常跟of短语，表示约数

18．Waste can be seen everywhere in the school．Some students ask for more food than they can eat．Others often forget to turn off the lights when they leave the classroom．They say they can afford these things．But I don't agree with them．
Waste can bring a lot of problems．Although China is rich in some resources（资源），but poor in others，such as fresh water．It is reported that we will have no coal（煤） or oil to use in 100 years．If we go on wasting our resources，we will have nothing to use or nowhere to go．So I think we should tell the students not to waste things every day．Everybody
should stop wasting as soon as possible．
In our everyday life，we can do many things to prevent waste from happening，for example，
turn off the water taps（水龙头） when we finish washing，turn off the lights when we leave the classroom，try not to order more food than we need．If we do so，everything will be changed and waste can be stopped．

15．Recently a lot of people in some European countries are ill in hospital．It is said that they are infected（感染）with a kind of germ（细菌）．Some researchers think the germ probably comes from the fruit and vegetables imported（进口）from neighbor countries．Experts advise people to wash the vegetables carefully and peel（去皮）the fruit before eating．
As we know，germs are everywhere．People can't see them with eyes，but they are on your books，on your desk and even in the air．Like people，germs move around the world．Some germs are safe，but some are dangerous．Germs cause illness like colds and the flu．So please pay more attention to the following things：
Warmer Weather Brings Germs
The world's weather is changing．Cooler countries are getting warmer，so insects from hot countries can move there．Some of these insects，like mosquitoes，carry dangerous germs．These germs cause headaches，fever and even kill people．
Under Your Skin
Your skin protects you from germs．It only stops some germs，but not all．Germs can enter your body when you eat，or when you have cuts（伤口）．Germs can be on your hands，too．They enter your body when you touch your eyes，nose or mouth．
Fighting With Germs
Your immune system（免疫系统）protects you，too．When germs get inside your body，your immune system finds and kills them．Special cells（细胞）move around your body and fight germs．They help you stay healthy．Other cells make antibodies．Antibodies help your body find and stop germs．
What can we do to fight germs？We should wash our hands with soap and water．Soap kills many germs，and water washes them away．
57．Which of the following is true according to the passage？C
A．We can see some germs with our eyes．

19．Different weather makes people feel different．It influences health，intelligence（智力） and feelings．
In August，it's very hot and wet in the southern part of the United States．People there have heart trouble and other kinds of health problems during this month．In the Northeast and the Middle West，it is very hot at some times and very cold at other times．People in these states have more heart trouble after the weather changes in February or March．
The weather can also influence intelligence．For example，in a study by scientists，IQ（智商） of a group of students was very high when a very strong wind came，but after the strong wind，their IQ was 10% below．The wind can help people have higher intelligence．Very hot weather，on the other hand，can make it lower．Students in many schools of the United States often do badly in exams in the hot months of the year （July and August）．
Weather also has a strong influence on people's feelings．Winter may be a bad time for thin people．They usually feel cold during these months．They might even feel unhappy during cold weather．But fat people may have a hard time in hot summer．
Low air pressure（气压） may make people forgetful．People leave more bags and umbrellas on buses and in stores on low-pressure days．People feel the most comfortable at a temperature of about 18°C．It is the best weather for work and health．
Are you feeling sick，sad，tired，or forgetful today？It may be the weather's problem．
