解题步骤
1.确定是否用非谓语动词；
1） 句子是否已存在谓语动词；
2） 并列连词或从属连词？(and, but, which......)
2. 判断非谓语动词在句中的成分和作用；
1） doing 主动，进行
2） done 被动，完成
3） to do 目的，将来

有些单词或词组如：date back to(追溯到); belong to(属于); consist of(包括); run out(用完); measure(测量)...等无被动形式，做谓语用一般现在时主动语态，做非谓语用其doing形式。

3、The tree measures (measure) 3 meters.
4、The tree measuring (measure)5 meters is very tall.

6、The city dating (date) back tothe Ming Dynasty looks beautiful.

某些短语，be based on; be concerned about; be impressed with; be devoted to; be attached to; be intended at......做谓语带be动词，做非谓语不带be动词。

1.Chinese researchers hope to use the instruments on board Chang’e-4 ________(find) and study areas of the South Pole-Aitken basin.
【答案】to find
【解析】考查非谓语动词。句意：中国的研究者希望使用嫦娥四号上的设备来发现和研究南极艾特肯盆地。此处表示目的，应使用不定式作目的状语。故填 to find
2.They represent the earth (come) back to life and best wishes for new beginnings.
【答案】coming
【解析】考查非谓语动词。句意：它们代表着大地的复苏和对新开端的美好祝愿。句中谓语动词为 represent，所以这里为非谓语动词。名词 earth 与 come back to之间为主动关系，所以用现在分词作后置定语。故填 coming
3. They make great gifts and you see them many times ________
(decorate) with red envelopes and messages of good fortune.
【答案】 decorated
【解析】考查非谓语动词。句意：它们是很好的礼物，你会经常看到它们装饰着红包和好运的信息。句中 them 与 decorate 之间为被动关系，所以用过去分词作宾语补足语。故填 decorated。
4. The next morning she found the man ____ in bed, dead.
A. lying B. lie C. lay D. laying
【答案】 D
【解析】考查非谓语动词。句意：第二天早上，她发现那个男人躺在床上，已经死了。横线用来补充说明宾语 the man，the man与动词 lie 来说是主动关系，而且，lie 这个动作与谓语动词 found 同时进行，故选D。
5. -Good morning. Can I help you
-I’d like to have the package ____, madam.
A. be weighed B. to be weighed C. to weigh D. weighed
【答案】 D
【解析】考查非谓语动词。句意：女士，我想把包裹称一下。横线用来补充说明宾语 the package; 再根据 the package 对于动词 weigh 来说，只能是被动关系。
