1. do give her my regards.
1)“do+动词原形”构成的祈使句，语气较强，表示“务必，一定要”，do在句中要重读。例如：
do remember the rules of the game!
一般现在时和一般过去时的陈述句中，我们也可以借助do，does，did来加强动词的语气。它们在句中也要重读。例如：
i do like your painting.
2)give sb. one s regards意思为“向某人问好”，这里regards意为“祝愿，问侯”(=bestwishes)。例如：
give your family my regards.
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le**e for...
例如：they are going off to(=le**ing for)america in two days.
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.
plane le**es at seven.
这是用一般现在时表示将来的动作的用法，类似le**e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
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。
2. take off
take off这里表示“(飞机)起飞”(=le**e)，用作不及物动词词组，后面不能跟宾语。takeoff还有“脱下(衣服)，休假”等意思。例如：
my plane takes off(=le**es)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？
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 tr**el 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 h**e 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。
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.
***** 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**制成)，bemade into...被制成)。
例如：this kind of watch is made in switzerland.
flour，sugar and eggs are made into cakes by mother.
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 tr**el by air.
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 sth.”和“see/notice/watch/hear 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 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。
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 le**e when the telephone rang.我刚要走，就在这时**铃响了。
can eat a person in two minutes，le**ing only bones.
这里分词短语le**ing only bones用作结果状语，修饰谓语动词eat。分词短语还可以用作目的状语或伴随状语。例如：
she sat there waiting for him.她坐在那儿等他。(目的状语)
laughing and talking，the students went out of the class room.学生们又说又笑地走出教室。(伴随状语)
a bad sight it was!
这是一句感叹句。英语的感叹句型是：“what(a)+名词+主语+谓语！”。当句型中的名词。
是不。可数名词单数时，what后要加a;若名词是可数名词复数或不可数名词时，则what后不可加a。例如：
what an interesting book it is!what beautiful girls they are!
what a silly question you asked!
英语感叹句另外一个句型是：“how+形容词/副词+主语+谓语！”例如：
how clever she is!
how fast she is running!
but/except...under the soil there s nothing but sand.
nothing but/except...意为“除外一无所有，只有”(=only)。注意：若后接动词时，一般要接省略to的不定式。
例如：i found nothing in the empty house except some broken glasses.
i could hear nothing but a strange sound in the forest.
the baby did nothing but cry after he woke up.
he did nothing every day except watch tv at home.
例1单项填空。
we were reading the light went out. a. while b. what c. when d. where
解析】答案为c。
根据语境该选c，表示“这时突然灯熄了”。
例2单项填空。
when tom was ill in hospital，his classmates went to see him .
a. every a few days b. every two days
c. everyday d. every the second day
解析】答案为b。
本题考查every表“每隔的”的用法。a项要去掉a; c项要分开写；d项该去掉the。
例3单项填空。
the boy was last seen near the river.
a. missing; playing b. missing; play
c. missed; played d. missed; to play
解析】答案为a。
本题考查非谓语动词用法。“丢失，走失”该用missing或lost;see / notice / watch / hear sth.用于被动句时要用带to的不定式。
另外see / notice / watch / hear sb. do sth.和see /notice /watch / hear sb.
doing sth.在用法上也有区别(参见上文)。所以选a。
