Ｕｎｉｔｓ２０—２２难句释疑

Unit 20

1.I told the company about my work experience and answered their questions as well as I could.

我把我的工作经验告诉了公司，并且尽可能好地回答了他们提出的问题。

as well as I could是一个由as…as引导的状语从句，省略了谓语动词answer,以避免不必要的重复。“as+adj./adv.+as+主语+can/could”结构可以用“as+adj./adv.+as+possible”来代替，像本句中的as well as I could 可以用as well as possible代替。例如：

He was running as fast as he could.

=He was running as fast as possible. 他尽可能快地跑着。

2.Two days later I received a letter offering me the job.

两天后我收到了录用通知书。

offering me the job为现在分词短语作定语。例如：

Did you see the boy dancing with a pretty girl?

你看见那个和一个漂亮的女孩跳舞的男孩了吗？

The people performing all play different instruments.

演出的人都会演奏不同的乐器。

The boy singing now is a classmate of mine.

现在唱歌的那个男孩是我的同学。

Who is the man standing by the door? 靠门站着的那个人是谁？

Do you know the boy lying under the big tree?

你认识躺在大树下的那个男孩吗？

3.We might cook this little mouse, if only we had some stuffin!

我们可以把这只小老鼠做饭吃，如果我们有些填料的话！

该句为if引导的虚拟条件句，表示与现在事实相反的假设。if从句中的动词用过去式，主句中的动词用过去将来式或情态动词的过去式形式。由if构成的虚拟条件句，如果表示与过去事实相反的假设，if从句用过去完成时，主句用“would/should+现在完成时”。另外，该句中的if only表示“如果……就好了；但愿……”。例如：

You might be late if you went on foot. 假如你步行去，可能会迟到。

If I were a bird, I could fly in the sky.

如果我是一只鸟，我就能在空中飞翔。

If she wore a red coat, she would look much younger.

如果她穿一件红色上衣，她看起来会更年轻。

If you had come earlier, you would have seen him.

如果你早一点儿来的话，你就会见到他了。

I could have done it better, if I had been given more time.

如果给我更多时间的话，我就能把这件事做得更好。

If only I had met her earlier!如果我早点儿遇到她该多好！

4.The other person, the “showman”， sits in the chair and acts out the story using body language and facial expressions.

另一个人，那个“表演者”，坐在椅子上运用身势语言和面部表情把故事表演出来。

using body language and facial expressions是动名词短语，在句中作状语，表示方式或手段。这个短语相当于介词短语by using body languageand facial expressions或by means of body language and facial expressions。例如：

They crossed the river using small boats. 他们利用小船过河。

George forced the door open, using all his strength.

乔治使尽全身力气，强行把门打开。

Unit 22

5.Having enjoyed the rides at the Headland, visitors can take the shuttle to the Lowland.

在高地游玩了乘车之后，游客们可以乘坐缆车到低地。

Having enjoyed the rides at the Headland是V-ing短语在句中作状语，Having enjoyed…是V-ing形式的完成式，它表示的动作发生在谓语动词所表示的动作之前。例如：

Having been separated from other countries for millions of years, Australia has many animals and plants.

由于同其他大陆分开已有数百万年之久，所以澳大利亚有许多动植物。

Having written the composition, he watched TV.

写完作文以后，他看了电视。

写完小说以后，我稍稍休息了一会儿。
