【简答题】
When you want to go shopping, decide how much money you can spend on new clothes. Think about the kind of clothes you really need. Then look for those clothes you really need. Then look for those clothes on sale. There are labels(标签) ins ide 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 l abel may tell you to wash in cold water. The label on a coat may say “dry clean only”, for washing may ruin this coat. If you do as the directions (说明)on the label, you can keep your clothes looking their best for a long time. Many clothes today must be dry cleaned. Dry cleaning is expensive. When buying new clothes, check 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 necessarily(不一定) better made. They do not always fit better. Sometimes less expensive clothes look and fit better than more expensive clothes. 小题1:If you want to save money, you had better buy clothes that __ . A.don’t fit you B.don’t last long C.need to be dry cleaned D.can be washed 小题2:The labels inside the clothes tell you______. A.how to keep them looking their best B.how to save money C.whether they fit you or not D.where to get them dry cleaned 小题3: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 spend on it C.to know how to wash them D.to read the labels inside them 小题4:We learn from the passage that cheaper clothes __ . A.are always worse made B.must be dry cleaned C.can not be washed D.can sometimes fit you b etter 小题5:The best title for the passage should be __ . A.Buy Less Expensive Clothes B.Taking Enough Money When Shopping C.Being a Clever Clothes Shopper D.Choosing the Labels inside New Clothes

【判断题】任务:写出作者立场。 诉讼律师和客户没有太多直接联系,如果你想找个与法庭密切相关的法律工 作也不难。但是,想要在法庭工作的律师需要谨慎地选择领域,看看这一领域的 工作模式是否符合自己的喜好。刑事律师可能大部分工作都是在法庭上完成的, 而税务律师每个月也许只有一天需要出庭,甚至更少。辩护工作需要花在办公室 的时间比花在法庭上的多。
A.
正确
B.
错误
