7.This afternoon I was just about to go swimming when luckily our guide saw me…今天下午我正要去游泳，这时我们 的向导看到我了……。

　1)“be about to do sth.”意思是“马上/正要干某事”。例 如:

　Mrs Smith was about to begin，but Jennie spoke first.史 密斯太太正要开始，可詹妮首先讲话了。

　He met her in the doorway just as she was about to go away.就在她刚要走时，他在门口遇见了她。

　2) 句中的“when”是并列连词，意思是“在那时”，相当于 “at that time”。用来表示突然发生某事。例如:

　I hadn t been reading for half an hour when I heard steps out side.我看书还不到半小时，就在这时我听到外边有脚步声。

　I was about to leave when the telephone rang.我刚要 走，就在这时电话铃响了。

6.We can see them flying along the river.我们可以看到它们沿着河边飞翔。

　英语中有些表示感觉的动词，如:see，notice，watch，hear 等可以用于下列结构中:“see/notice/watch/hear sb.do sth.”和“see/notice/watch/hear sb.doing sth.”，但两者意义上有 区别。“see sb. do sth.”意思是“看见某人做过什么”，它强调 动作完成了，而“see sb.doing sth.”意思是“看见某人正在做 什么”，它强调动作正在进行。例如:

　I saw him crossing the street.我看见他正在过马路。

　I saw him cross the street.我看见他过马路了。

　I heard him singing in the next room.我听见他在隔壁 唱歌。

　I heard him sing in the next room.我听见他在隔壁唱歌了。

5.It is wrong to eat monkeys.

　在It is wrong to do sth.结构中，it用作形式主语，真正 的主语是不定式短语 to do sth.。此结构可归纳成: It is/ was+adj.+to do。例如:

　It is lucky to meet you here.

　It is wonderful to travel by air.

4.be made from/of...

　be made from/of...意思都是“由……制成”。be made from通常指制成品看不出原材料，be made of通常指制成后还可以看出原材料。例如:

　The bridge is made of stones.

　Paper is made from wood.

　另外，made常用的结构还有 be made by...(被谁制成)， be made in...(在哪里制成)，be made into...(被制成……)。

　例如:

　This kind of watch is made in Switzerland.

　Flour，sugar and eggs are made into cakes by mother.

3.They move on to a new place every two or three years.

　每隔两三年他们就要继续迁移到新的地方去。

　1)副词on表示动作的方向、时间的持续等。有“往前”、 “继续(干某事)”的意思。例如:

　They walked on a little way without speaking.他们往前 走了一段，谁都没有讲话。

　He talked on about his travel in the forest.他继续说着他在森林里旅行的趣事。

　2)every在本句中的意思是“每隔……的”。常用在“every+基数词+复数名词”的结构中。例如:

　Write only on every other line，please.请隔行写。

　We have English lessons every other day.我们隔天有英语课。

　They usually go to see their parents every three months. 他们通常每隔三个月去看他们的父母。

2. take off

　take off这里表示“(飞机)起飞”(= leave)，用作不及物动词词组，后面不能跟宾语。take off还有“脱下(衣服)，休假”等意思。例如:

　My plane takes off(=leaves)at three in the afternoon.

　Take your coat off.

　You look very tired，why not take several days off?你看

　上去很累，为什么不休几天假呢?

1.I can smell it.我可以闻到它。 “smell”和第六单元中我们讲到的“taste”的用法一样。

　它可以作及物动词，意思是“闻”，作连系动词，意思是“闻起来”。作连系动词时后面也要跟形容词。例如:

　She was smelling the flowers.她正在闻那些花。

　She smelled the meat to see if it is fresh.她闻了闻这块肉想看看它是否新鲜。

　The flowers smell sweet.这些花闻起来很香。

　The dish smells good.这道菜闻起来很香。

　英语中还有一些其他的词，如“sound，look”，也可以作连系动词，意思是“听起来”和“看起来”。例如:

　Your idea sounds interesting.你的主意听起来很有趣。

　He looked happy when I told him the news.当我告诉他这个消息时，他很高兴。

4.My plane leaves at seven.

　这是用一般现在时表示将来的动作的用法，类似leave的动词还有begin，start，arrive，等等。注意这类句中通常都有一个表示将来的时间状语。

　Lessons 14& 15

3. see...off

　see...off意思为“给某人送行”。如果see后面接代词，则必须放在off前;若后接名词，则可以放在off前，也可放在off后。其反义词组“接某人”是meet sb.。例如:

　We went to the railway station to see him off.

　I ll meet you at the airport when you come back.

2.go off to...

　off此处为副词，意思为“离开”，to是介词，后面表示地 点的名词或词组。go off to...意思是“(离开所在的地方)启程去另一个地方”，相当于leave for...。例如:

　They are going off to(=leaving for)America in two days.
