1. Drinking water-------excessive enamel of teeth to become brittle and to chip off, leaving a stained or mottled effect.

(A) containing

(B) in which containing

(C) contains

(D) that is contained

答案选A。很奇怪如果选A这道题不就缺谓语了吗？我不明白！我选C。

12. The gardenia, about 200 species --—to tropical and subtropical countries, was named in honor of eighteenth-century naturalist Alexander Garden.

(A) native of which are

(B) are nalive of which

(C) which are native of

(D) of which are native

答案选D。这道题我没看懂，of which后面不是加完整句吗？四个选项都没看懂！：（

27. The physical universe is governed by law that demand the continuous increase of entropy or disorder.

答案选C。是加上the吗？再介词后面名词前什么时候加the什么时候不加呢？

30. Although Republican Dwight Eisenhower won the United Slates presidency in 1952 and 1956, the Democrats ran Congress for six of his eight years into office.

答案选D。为什么呢？在这里要表达什么意思呢？我看不懂！怎么改才对？

请大家帮忙看看吧！

1. 可能是题有错.

2. law 后的demand没有单数.

谢谢楼主！

那其他题呢？能帮我解答一下吗？先谢谢大家了！

第一题是答案错了吧，

第二题The gardenia, about 200 species --—to tropical and subtropical countries, was named in honor of eighteenth-century naturalist Alexander Garden.

(A) native of which are结构错

(B) are nalive of which有谓语动词错

(C) which are native of（of肯定不能和to放在一起，应是native to）

(D) of which are native（结构正确，of表示修饰，中心语是前面那个）

第三题law表示定律的意思，没有定冠词。错

哦，这样啊!谢谢楼主！

那30题呢？能在帮我解答一下吗？
