词句精讲精练

词汇精讲
1. maybe
maybe 是副词,意思是“也许,可能”,在句中作状语,相当于perhaps,常位于句首。
例如:
Maybe she’ll come this afternoon. 她可能今天下午来。
Maybe you put the letter in your pockets. 大概你把信放在衣袋里了。
【拓展】
(1)maybe 和may be 的辨析:
maybe 是副词,而在may be 中,may 是情态动词,be 是动词原形,两者构成完整
的谓语形式,与主语形成系表结构,意为“也许是、可能是”。 例如:
I can’t find my watch. It may be in your pocket.
我找不到我的手表了,它可能在你的口袋里。
He may be a soldier. 他可能是军人。
(2)maybe 和may be 可相互转换。 例如:
He may be in the office. = Maybe he is in the office. 他或许在办公室。
You may be right. = Maybe you are right. 你或许是对的。
2. although
although 的意思相当于though,意为“尽管,虽然”,用来引导让步状语从句。它所
引导的从句不能与并列连词but; and; so 等连用,但可以和yet; still 等词连用。例如:
Although he lives alone, he doesn’t feel lonely.= He lives alone, but he doesn’t feel
lonely.
虽然他一个人住,但他并不感到孤独。
There is air all around us, although we cannot see it.
虽然我们看不见空气,但空气却存在于我们的周围。
【拓展】although 与though 的辨析:
(1)用作连词,表示“虽然”,二者可以互换使用,但although 比though 更为正式。
例如:
Though/Although it was raining, we still went there.
虽然下着雨,但我们还是去了那里。
(2)although 一般不用作副词,而though 可用作副词,且一般放在句末(不放在句
首),意为“可是,不过”。例如:
It’s hard work; I enjoy it, though. 工作很辛苦,可是我很喜欢。
We all tried our best. We lost the game, though.
我们都尽了最大努力,但我们还是输了。
(3)在as though(好像,仿佛),even though(即使,纵然)等固定短语中不能用
although。例如:
He talks as though he knows everything. 他夸夸其谈,好像无所不知。
3. die
die 是动词,意为“死亡”,是短暂性动作,常用于过去时中,过去式为died。例如:
Plants and people will die without water. 没有水,植物和人都会死。
His father died two years ago. 他的父亲两年前去世的。

The fish will die without water. 鱼离开水会死去。
Car accidents have caused a lot of deaths. 车祸造成很多人死亡。
The doctors have saved the dying man. 医生们救活了那个垂死的人。
4. however&but
however 和 but 都意为“可是,但是”;但是用法不同。
(1)however 不能直接连接两个分句,必须另起新句,并用逗号隔开。例如:
It was raining hard. However, we went out to look for the boy.
雨下得很大,然而我们还是出去寻找那个孩子。
(2)but 是并列连词,连接两个并列分句,后面不用逗号,前后两句在总的意义上构成
了对比。例如:
I really don't like cheese, but I will try just a little this time.
我实在是不喜欢吃奶酪,但是这次我要尝一点。
(3)however 比but 用的场合更正式, 因此however 用于书面语,而but 常用于口语。另
外, however 的意思还不只局限于“但是;然而”,它还有其他的用法。例如:
However hard I worked, she was never satisfied.
无论我多么努力地工作,她从来没满意过。
However did you get here without a car?
没有汽车你究竟是怎样来的呢?
5. hardly&hard
hardly 和hard 形式上很接近,但意义截然不同。
(1)hardly 是表频率的副词,意为“几乎不;几乎没有”,相当于almost not。例如:
There is hardly any coffee left.= There’s almost no coffee left. 几乎没有剩余的
咖啡了。
(2)hard 作形容词时,意为“困难的;硬的;勤奋的;严厉的;苛刻的”。hard 作副
词时常用来表示程度,意为“努力地;猛烈地;剧烈地”。例如:
This ground is too hard to dig. 这块地太硬,挖不动。
They tried hard to succeed. 他们努力工作,以求得成功。
【拓展】常见的表示频度的副词:
(1)always 的频度为100%,表示动作重复、状态继续,中间没有间断,意思是
“总是”、“永远地”。例如:
The sun always rises in the east and sets in the west. 太阳总是东升西落。
(2)usually 的频度为70%左右,意为“通常”、“平常”,即很少有例外。例如:
He usually goes to bed at ten o’clock. 他通常10 点钟睡觉。
(3)often 的频度为50%左右,意为“常常”,但不如usually 那么频繁,表示动作
重复,中间有间断。例如:

He is often late for school. 他上学经常迟到。
(4)sometimes 的频度为20%左右,意为“有时”,表示动作偶尔发生。可以位于
句首,以示强调。例如:
It is sometimes hot and sometimes cold. 天气忽冷忽热。
Sometimes he does it this way and sometimes he does it that way.
他有时这样做,有时那样做。
(5)hardly ever 的频度为5%左右,意为“几乎不”、“偶尔”。例如:
I hardly ever go out these days. 这些天我几乎不出门。
(6)never 的频度为0,意为“从来不”、“永不”。 例如:
My parents are never late for work. 我父母上班从来不迟到。
6. exercise
(1)作不及物动词,意为“锻炼、运动”。例如:
-How often do you exercise? 你多久锻炼一次?
-I exercise every day. 我每天都锻炼。
(2)作不可数名词,意为“锻炼、运动”,常与动词take 连用。例如:
Exercise makes me keep healthy. 运动使我保持健康。
(3)作可数名词,意为“练习;操”。例如:
We do morning exercises every day. 我们每天做早操。
We do English exercises to help us learn English well. 我们做英语练习以便学好英
语。
7. health
health 为名词,意为“健康”,其形容形式为healthy,意为“健康的”。unhealthy 意
为“不健康的,是healthy 的反义词。healthily 是“健康地”,是副词。
在名词词尾加y 构成形容词,类似的词还有:
rain—rainy 雨—下雨的 sun—sunny 太阳—晴朗的
luck—lucky 幸运—幸运的 wind—windy 风—刮风的
8. once / twice
once“一次”,twice“两次”,在英语中三次或三次以上通常用“基数词+times”表
示,time 在这里为可数名词,意为“次数”,复数加s。例如:
I wash my face twice a day. 我每天洗两次脸。
He has been there four times. 他去过那里四次。

2. But do you want to come?
(1)want 意为“想要”后可接名词或不定式,构成want to do sth. 意为“想要做某
事”;
want sb. to do sth. 意为“想要某人做某事”。例如:
Do you want to join us? 你想加入到我们中吗?
He wants me to help him. 他想要我帮他。
(2)want 的用法还有:want sth.,意为“想要什么”。 例如:
She wants a cup of tea. 她想要一杯茶。
【拓展】
want 后接动词不定式时,相当于would like;因此want (sb.) to do sth.=would like
(sb.) to do sth. 例如:
I wanted to go swimming. = I would like to go swimming. 我想游泳。

一般接表示人的名词或代词。例如:
She is very good to us. 她对我们很好。
The boss is bad to his workers.那个老板对他的工人不好。
(2)be good at“在……方面擅长”,介词at 后面常接名词、代词或动词-ing 形式,同
义短语为do well in。例如:
She is good at English and Chinese. = She does well in English and Chinese.
她擅长英语和汉语。
(3)be good with“和……相处得好;擅于和……相处”。例如:
Are you good with children?你和孩子们相处得好吗?
4. It is good to relax by using the Internet or watching game shows…
It is/was + adj. + to do sth. 意为“做某事是……的”,to do sth.为句子的真正的主
语,而it 为形式主语,形式主语不能用别的词来代替,句中可在形容词后加for sb.,意
为“对于某人来说,做某事是……的”。例如:
It’s important for us to learn a foreign language. 对我们来说,学习一门外语是相当重
要的。
It’s necessary for us to eat more fruit and vegetables. 对我们来说,多吃蔬菜和水果是
必要的。
【拓展】
这个句型中的for sb.有时也可以用of sb. 二者意义有区别:
(1)在It’s + adj. + for sb. to do sth. 中,for sb.意为“对某人来说”,句中的形容
词是用来说明to do sth.的,形式主语只能用it。例如:
It’s necessary for the students to do some housework.
对于学生们来说,做些家务是十分必要的。
(2)在It’s + adj. + of sb. to do sth. 中of sb. 意为“某人……”,句中形容词可与
逻辑主语sb. 构成系表结构,即形容词是用来说明或形容sb.(某人)的。例如:
It’s very kind of you to help us. 你能帮助我们真是太好了。
5. Exercise such as playing sports is fun…
such as 用来列举多个事物,一般不全部列出,插在被列举事物与前面的名词之间。
例如:
The farm grows all kinds of crops, such as rice, wheat and cotton.
这个农场种植各种各样的庄稼,例如,稻谷、小麦和棉花。
【拓展】
for example“例如”,可以作为独立语插入句中,不影响句子其他部分的语法关系,
用以列举某一个人或事。例如:
A lot of children, for example, Tom likes drinking tea. 很多小孩,例如Tom 喜欢喝
茶。
