1.Guidebook writer:I have visited hotels throughout the country and have noticed that in those built before 1930 the quality of the original carpentry work is generally superior to that in hotels built afterward.Clearly carpenters working on hotels before 1930 typically worked with more skill, care, and effort than carpenters who have worked on hotels built subsequently.
Which of the following, if true, most seriously weakens the guidebook writer’s argument?答案是D
B.Hotels built since 1930 can generally accommodate more guests than those built before 1930.
D.The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished. 为什么不能选B呢？
2.A new hair-growing drug is being sold for three times the price, per milligram, as the drug’s maker charges for another product with the same active ingredient.答案是as改成that  这里的that什么意思啊？
3.Shoppers in sporting goods stores, unlike in department stores, do very little impulse shopping, not buying a pair of skis and a boomerang when they come in for a basketball, but they leave with a basketball only.   A哪里不对呢？
A.those in department stores, do very little impulse shopping, do not buy a pair of skis and a boomerang when they come in for a basketball, but leave with only a basketball

1. 原文：1930以前的房子好---->1930以前的木工好
求削弱
D---表示质量好的保留下来了，也就是说我们现在能看到的1930以前的房子都是很好的房子，不好的都看不到了，削弱
B----住的人多，和结论没有关系~

住的人多了不就显得破了么。。。表打我。。。

住得多和破之间没有必然联系的，原文没说就当没有，不能自己随意联想~
