unit5 feeling happy topic 1 why all the smiling faces?

一.重点语法。

1. linking verb + adjective 系动词+形容词,构成系表结构。

系动词:be (是) feel look sound taste turn get become smell seem 等等.

for example :the food tastes delious.

注意:(1). 有些连系动词通常不用于被动语态和进行时态中。如:feel, taste等词。例如:

-do you like the material? -yes, it feels very soft.

(2). 一般情况下,连系动词主要跟形容词或分词作表语。例如:

be careful when you cross this very busy street. if not, you may get run over by a car.

(3). 能跟名词作表语的连系动词常见的有:be, become, appear, seem, prove, remain和turn等。

注意:turn后跟(表示主语身份的)名词作表语时,不加冠词。例如:

twenty years later, he turned teacher. the population growth in china remains a problem.

4). 连系动词也可跟不定式(to do / to be),常见的有:appear, seem, remain, prove, look等。

例如:h**ing a trip abroad is certainly good for the old couple, but it remains to be seen whether they will enjoy it.

2. hope 与wish 的比较.都与that引导的从句连用.hope常用于将来时表可能实现的愿望. wish常用于过去式表示不可能实现的愿望.

for example : i hope that you will be happy. i wish that you could be happy.

3. 动词-ing 和-ed形式作主语补语的区别.动词-ing表示主语的特征,常用于事物.动词-ed表示主语的状态,常用于人.这类词有:interest move active disappoint excite surprise frighten bore

for example:the game is interesting. i am interested in the game.

4.表示能力的词. could 表示过去的能力. can 表示现在的能力。

一、重点语法:

5. 原因状语从句.引导词:because since so 等,但是因为,所以不能同时出现.

for example:he is ill, so he isn’t able to come.

she is lonely because she has no friends to talk with.

since she is very strict with herself ,she is unhappy.

6. always 常用于一般现在时.表示频繁发生的动作.但与现在进行时态连用表是厌恶,责备,赞扬的语气. for example: she is always talking about money.

7. can’t 表示一种否定的推测.you can’t h**e sars.

must 表示一种肯定的推测.it must be sunny day tomorrow

9. 英语语法as...as、so…as、so…that和too…to的用法区别。

so…as只用于否定句,as…as不但可用于肯定句,还可用于否定句。

as…as中的第一个as是副词,后接形容词或副词的原形;第二个as是连词,引导比较状语从句。 例如:jack is as tall as you.

杰克和你一样高。 jim is not so/as br**e as you. 吉姆不如你聪明。

③so…that 如此…以至于(只能引导结果状语从句,的后面多接形容词、副词或分词,后接句子。

例如:the house was so crowded that i could hardly turned around. 屋里很挤,我几乎都无法转身了。

④too…to 太…以至于不能…(too为副词,后接形容词或者副词,to为不定式的标志,这个不定式短语本身带有否定含义。) 例如:

the box is too he**y for her to carry it. 对于她来说,这个箱子太重了,以至于她搬不动。

一、重点语法。

8. 使役动词(让―――使――)make let h**e 的用法.

make +宾语+(省约to 的不定式)动词. make+宾语+名词.we make him team leader.

make +宾语+形容词.it make me happy. let+宾语+(省约to 的不定式)动词。

h**e+宾语+(省约to 的不定式)动词老师叫john到办公室拿他的书。

the teather made(had ) john get his book in the office.

爸爸让我明天下午看电视。 father let me watch tv tomorrow afternoon.

10. few ; a few ; little; a little的用法和区别。

(a) few与 (a) little的区别 ① 从所修饰的名词来看:(a) few后接可数名词,且要用复数形式;(a) little后接不可数名词。如:

we had little time to do it. 我们没什么时间做此事。

there’s only a little soup left. 只剩下一点儿汤了。

i’ll only be away a few minutes. 我只离开几分钟。

从所表示的意思来看:上面提到,两者均可表示数量,其主要区别是,(a) few后接可数名词,(a) little后接不可数名词。但是,(a) little还可表示大小。如:

please accept this little gift.请接受这件小小的礼物。

there are several little towns along the river. 沿河有几个小镇。

注意体会下面两句,前面的little表示形状或个子“小”,后面的little表示数量“少”:

the little boy is very busy. he has little time to play. 这个小男孩很忙,他很少有时间玩。

it’s a little animal. it eats only a little food. 那是一个小动物,它只吃一点点食物。

从各自的词性来看:在词性方面,两者的共同点是,均可用作形容词或代词;其不同点是,(a) little 还可用作副词,用以修饰形容词、副词、动词以及介词短语。如:

he is a little tired. 他有点累了。

they are a little bit better now. 现在他们稍好一点了。

you should walk a little faster. 你应该走快一点。

she was only a little over fifty years old.她才五十多一点。

有 a 与没有 an 的区别。

不带 a 的little和few 含有否定意义,表示数量很少或几乎没有,强调“少”带有a 的little和few含有肯定意义,表示数量虽然少但毕竟还有,强调“有”。比较:

few people like such things. 没什么人喜欢那样的东西。

a few people like such things. 有少数人喜欢那样的东西。

he knows little english. 他几乎不懂英语。

he knows a little english. 他懂一点点英语。

注意,当few前不带 a,但带有the, some these, those等修饰语时,也表示肯定意义。如:

some few h**e already left. 有几个已经离开了。

the last few winters h**e been very cold.过去几个冬天都很冷。

the first few chapters are about his early days.前几章谈他的少年时期。

思维拓展注意两者比较级和最高级的用法及区别:little的比较级和最高级分别为less和least,few的比较级和最高级分别为fewer和fewest。如:

boys think less about dress than girls do. 男孩子不像女孩子那样爱打扮。

he has the least money of all of us. 他是我们大家中钱最少的。

fewer radios were sold this year than last. 今年卖掉的收音机比去年少。
