A.No problem B.No hurry C.Come on

答案:C

解析:Come on. “加油!”表示激励。 No problem. 没问题;No hurry. 别着急;That's OK. 没关系。

2.The fish didn’t seem to mind me swimming among them. 鱼儿好像并不介意我游在它们中间。

me 在句中用做 swimming 的逻辑主语,这叫做动名词的复合结构。

动名词的复合结构的其中一种形式是“物主代词或名词所有格+动名词”,在句中做主语、宾语、表语等。如果不是在句子开头,这个结构常常可以用名词的普通格(或人称代词的宾格)。

① His/Jack's not getting to the station on time made all of us worried. 他/杰克没准时到车站使得我们大家都很担心。(做主语)

②Do you mind my/me/Jack's/Jack leaving now?我/杰克现在离开你介意吗?(做动词的宾语) ③Have you heard of my sister's winning the contest?我妹妹在竞赛中获胜的事你听说了吗?(做动词短语的宾语)

④He left the city without our knowing it.他离开这个城市我们大家都不知道。(做介词的宾语) ⑤What is most important is Tom's going there at once.最重要的是汤姆立刻到那里去。(做表语)

注意:在下列情况中,动名词复合结构中的逻辑主语要用名词的普通格或人称代词的宾格: (1)无生命的事物名词做逻辑主语时一般采用普通格形式。

(2)在口语和非正式语体中,只要不做主语常采用普通格或人称代词宾格。 (3)逻辑主语是一个短语或有修饰语,一般用名词普通格或人称代词宾格。 (4)-s结尾的复合名词做逻辑主语时一般用普通格。

(5)不定代词或指示代词做动名词的逻辑主语时,一般不用或很少用所有格形式。

(6)集合名词、单复数同形的名词或变化不规则的复数名词做逻辑主语并同动名词一起做宾语时,一般用普通格。

(7)it 做逻辑主语时用宾格、所有格均可,但指时间时用宾格。

[即境活用2] Do you mind ______ alone at home? A.Tom leaving

B.Tom having left D.Tom to be left

C.Tom's being left

答案:C

解析:mind 后接动名词做宾语,且动名词的逻辑主语是 Tom,表被动意义,故选C。

易 错 点 拨 1.abandon/desert/give up

(1)abandon指不得已而遗弃、放弃人或事物。

(2)desert强调故意逃避应尽的义务和职责,违背誓言,有责难之意。另外,desert还有离弃某地方之意。

(3)give up为常用词,常用于口语,与abandon同义。

[应用1] (1)I persuaded him to __________ smoking.我说服他戒了烟。 (2)She was ____________ by her husband.她被丈夫遗弃了。

(3)Snow forced many drivers to __________ their vehicles.大雪迫使许多驾驶者弃车步行。 (4)The villages had been _________.这些村庄已经荒无人烟了。

2. aware/conscious

二者都可表示“意识到的”,都可用于be aware/conscious of结构。但aware指感官上的知觉,而conscious指内心所意识到的感觉。

[应用2] (1)I suddenly felt ______ of somebody watching me.我突然觉得有人盯着我看。 (2)He became acutely _____________ of having failed his parents.他深深感到自己辜负了父母的期望。

3. flee/escape/run away

三者都有“逃跑”的意思,但有所侧重。

(1)flee强调逃跑行为本身,含有逃走、消散的意思。 (2)escape强调逃跑的结果,即成功地跑掉了。 (3)run away多用于口语,含有不辞而别的意思。

[应用3] (1)He ____________ from his home when he was very young.他很小时就离家出走了。
