习惯上用于have+n.+in doing sth的若干句式

7. a hard time （与have连用）过得很辛苦

用于have a hard time (in) doing sth，表示“做某事很辛苦”。如：

I had a hard time finding you. 我找你费了好大劲。

The two friends had a hard time getting here. 两位朋友到这里来一路辛苦。

I had a hard time (in) getting them to see the point. 我费了很大劲儿才让他们明白我的意思。

8. job 工作；费力的事；任务

用于have a job (in) doing sth，表示“做某事有困难（很费力）”，与have difficulty (in) doing sth同义。如：

We had quite a job finding your house. 我们费了很大的劲才找到你的家。

You’ll have a job convincing them that you’re right. 要让他们信服你是对的还要费点劲。

We were only given an hour to do the exam, and I had a job finishing the paper. 我们考试的时间只有一个小时，我好不容易才做完了卷子。

其中的job有时可用hard, difficult修饰，其中的(in) doing sth有时也可换成不定式。如：

He had a hard job to make himself heard. 他好不容易才让别人听到他的声音。

注意，下面一句中的doing sth为句子主语，其前不能有介词in：

It was quite a job finding his flat. 找到他的寓所可不是件容易事。（句中的finding也可换成to find）

比较相关结构：

(1) 表示“做某事的工作（任务）”，其后可接of doing sth。如：

A food processor makes the job of preparing food a lot easier. 一个食品加工机使做饭容易了许多。

She’s taken on the job of organizing the Christmas party. 她接受了筹办圣诞晚会的任务。

(2) 用于do [make] a good job of doing sth（其中的good也可换成其他形容词），其意为“把某事做得好（不好等）”：

She did a splendid job of decorating the house for the party. 她为了晚会把房子装饰得非常漂亮。

She made a very good job of covering up the damage. 她非常老练地完成了掩盖损失的任务。

其中的of doing sth有时也可换成in doing sth（其中的good也可换成其他形容词），其意为“把某事干得好（不好等）”。如：

The police did an admirable job in keeping the fans calm. 警察把球迷们的秩序整得很好，令人敬佩。

(3) 有时可直接跟现在分词作定语。如：

She got a temporary job stacking shelves. 她找到一份整理货架的临时工作。

9. problem 困难

用于have a problem (in) doing sth，表示“做某事有困难”。如：

Did you have any problems (= difficulties) getting here? 你到这儿来遇到困难了吗？

若表示“做某事的困难”，则可后接 of doing sth。如：

Most students face the problem of funding themselves while they are studying. 大多数学生在求学期间都会面临经济来源的问题。
