Think about the kind of clothes you really need. Then look for those clothes on sale. There are labels(标签)inside all new clothes. The labels tell you how to take care of your clothes. The label for a shirt may tell you to wash it in warm water. A sweater label may tell you to wash by washing in coldwater. The label on a coat may say “dry clean only.” Washing may ruin(损坏)this coat. If you do as thedirections( 说明)say on the label, you can keep your clothes looking their best. Many clothes today must be dry cleaned. Dry cleaning is expensive. When buying new clothes, check( 核实)to see if they will need to be dry cleaned. You will save money if you buy clothes that can be washed. You can save money if you buy clothes that are well made. Well-made clothes last longer. They look good even after they have been washed many times. Clothes that cost more money are not always better made. They do not always fit better. Sometimes less expensive clothes look and fit better than more expensive clothes.36 .If you want to save money you can buy clothes that _____.A.don’t fit you B.don’t last long C.need to be dry cleaned D.can be washed37.The label inside the clothes tell you ______.A.how to keep them looking their best B.how to save moneyC.whether they fit you or not D.where to get them dry cleaned38.The first thing for you to do before you buy clothes is ______.A.to look for well-made clothes B.to see how much money you can payC.to know how to wash them D.to read the labels inside them39 .We learn from the reading that cheaper clothes ______.A.are always worse made B.must be dry cleanedC.can not be washed D.can sometimes fit you better40.The best title(标题)for the reading should be ______.A.Buying Less Expensive Clothes B.Taking Enough Money When ShoppingC.Being a Clever Clothes Shopper D.Choosing the Labels inside New Clothes五、完形填空Mobile phones are becoming more and more popular not only with grown-ups but also with students. Meanwhile, they also 1 a problem for middle schools in the past few years. Some childrenhave got mobile phones as Christmas or birthday gifts, and more will 2 want them. .Many like SMS because it is easy and 3 . Some parents felt happy because they could get in touch 4 their children. Some teachers said mobile phone use was a distraction ( 分心的事) to students during school hours and it also gave them much 5 in their classrooms. Sometimes students 6 use phone messages to cheat ( 作弊) during exams. A new study found that some teenagers who send messages in classeven hurt their fingers because they can’t stop 7 SMS. Many teachers suggested that students should not have phones at school, 8 if there was a good reason, they could 9 their phones at school office. Many people think they understand 10 parents would want their children to have them, but they agree school should let the students know when they can use their mobile phones. 41.A.Because B.had become C.have become D.will become42.A.still B.yet C.already D.too43.A.quickly B.quick C.hurry D.sharp44.A.against B.on C.with D.to45.A.business B.information C.things D.trouble46.A.dare B.have to C.should D.might47.A.using B.to use C.used D.used to 48.A.and B.but C.though D.however 49.A.miss B.leave C.lie D.fetch 50.A.whether B.because C.why D.since 六、汉译英51.教室里有20 名学生。
