1.C 句义是“在1850年，全美有三分之一覆盖着森林。”因为有具体过去时间in 1850，所以用一般过去式，而且是单数，所以选择C项。
2.A 句义是“他的工作是设计新机器。” To design new machines 作主语，单数，所以选择A项。
3.C 由后面的谓语has可以看出主语是单数，所以选择each，both和all都是复数，every没有这种和of连用的用法。
4.C the+形容词表示“一类人”，the old就表示“老人”，如：the rich富人,the poor穷人。复数意义，所以谓语用are;look after照看，照料，和are构成被动。句义是“这里的老人被照看的非常好。”
5.B make sb happy使某人高兴。句义是“这个好消息让我们非常高兴。”
6.C a writer and singer，两个名词用and相连，且只有一个不定冠词a，表示的是一个人，这个人既是作家又是歌手。一个人当然是用单数了。
7.B 每个男孩都有一个苹果。each作主语，谓语用单数。
