[求助]做princeton时遇到的两个问题

1、有一题是考have difficultied doing sth和have difficulties in doing sth.

这里有两个疑问，好象有人说过，固定的用法是have difficulty in doing sth.不用复数，这里，不但用了复数，而且指出加了in不对。

2、regular glooming and defleaing is necessary for short-haired cats,the same as long-haired cats, because......

A  the same as

B   as well as

C   as for

D  the same as if they are

E   as it is for

大家说说，这题选什么？

1, 看不懂，有题目吗？

2，E，方式状语，对吗？

第2题，我也选E，太平行了，但princeton给出的答案是B。

第一题，我得找一下题目，做过去了，要重新找。

I choose E; Refer to OG60

60.   According to a recent poll, owning and living in a freestanding house on its own land is still a goal of a majority of young adults, like that of earlier generations.

(A) like that of earlier generations

(B) as that for earlier generations

(C) just as earlier generations did

(D) as have earlier generations（E）

(E) as it was of earlier generations

The intended comparison should be completed by a clause beginning with as and containing a subject and verb that correspond to the subject and verb of the main clause. In E, the best choice, it refers unambiguously to the phrasal subject owning... land, the verb was corresponds to is, and today’s young adults are appropriately compared to earlier generations. Choices A and B lack a verb corresponding to is and a clear referent for that. Choices C and D are confusing and illogical because their verbs, did and have, cannot substitute for is in the main clause.

2、regular glooming and defleaing is necessary for short-haired cats,the same as long-haired cats, because......

A  the same as

B   as well as

C   as for

D  the same as if they are

E   as it is for

可是B的as well as前面可以加逗号吗？

E的方式状语就是省略了表语形容词，这样可以吗？

请NN指教。

要看看because后面主语是什么? 有可能使的it在这里指代引起歧义.

regular glooming and defleaing is necessary for short-haired cats,as well as long-haired cats,

这个逗号肯定是错的。

freedownload, 能把句子补全了吗?because后面主语是什么?
