4月6号 1 As rare as something becomes, be it a baseball card or a musical recording or a postage stamep, the more avidly it is sought by collectors. Answer: The rarer something becomes, whether it is Doubt: 我选择的选项是“As something becomes rarer and rarer, like”，as=when，而且like而后接的是名词，所以我是根据这两个标准选择的，能解释下我为什么错吗？“whether it is ” 对我来说显得很突兀耶。
2. Migraine, the most debilitating common form of headache, afflicts perhaps 18miilion Americans, who collectively lose 64 million workdays a year , and they cost the nation $50 billion in medical expenses and lost work time. Answer: year and thus cost the nation $50 billion in medical expenses and lost Doubt: “lost”在这里的词性是什么呀？如果是动词，为什么是用过去时而不是原形呢？这样就与“cost”相平行呀？
3. It is an oversimplified view of cattle raising to say that all one has to do with cattle is leave them alone while they feed themselves, corral them ,and to drive them to market when the time is ripe. Answer: all one has to do with cattle is leave them alone while they feed themselves and then corral them and Doubt: 不是有这样的搭配“All we have to do is to ….”所以应该是“all one has to do with cattle is to leave…”因此我选择的选项是“the only thing that has to be done with cattle is to leave them alone while they feed themselves ,to corral them, and”。能帮我解释下为什么吗？
4．The Environmental Protection Agency’s proposal to place restrictions on both diesel fuel and diesel engines has sparked a counterattack by the oil industry, saying that the move will exacerbate the nation’s fuel supply problems. Answer: on both diesel fuel and diesel engines has sparked a counterattack by the oil industry ,which says Doubt: “which”指待的是哪个词呀？指代的是“the oil industry”吗？为什么不是用“saying”来指代整个proposal带来的影响吗？我选择的是a项。。。不明白耶
