八年级下重点作文 篇2

比较级

1.as和than后面的代词用主格还是用宾格要取决于主句中的谓语动词。如果主句中的谓语动词是及物动词, 主语相比用主格, 宾语相比用宾格, 以避免歧义。如:

I know you better than he (knows you) . 我比他更了解你。

I know you better than (I know) him. 你和他相比, 我更了解你。

如果谓语动词是不及物动词, 或虽是及物动词, 但不致引起歧义, 主格、宾格都可以使用。例如:

He has more books than I/me.他的书比我的多。

2.比较级可被much, rather, a lot, a great deal, even, still, a little, a bit等修饰。如:

Tom studies even harder than you. 汤姆学习比你更努力。

It is a bit colder today than yesterday. 今天比昨天还要冷。

3.“less+原级+than”意为“不比……”, 相当于“not so… as…”。例如:

This book is less useful than that one.=This book is not so useful as that one. 这本书没有那本有用。

4. 通常that用来替代前面出现的由单数或不可数名词表示的比较对象, those用来替代前面出现的复数名词表示的比较对象。the one相当于that, the ones相当于those, 并表示特指。例如:

The food in the box is much worse than that on the table. 盒子里的食物比桌子上的差得多。

This book is thinner than the one/that on the desk. 这本书比桌子上的那本薄。

最高级

1. 形容词最高级前一般要用定冠词the, 若形容词最高级前面有物主代词或名词所有格修饰时, 则不用定冠词the。例如:

The Changjiang River is the longest river in China. 长江是中国最长的河。

Monday is my father’s busiest day. 星期一是我父亲最忙的一天。

2.in后面接比较范围, 不一定是同类;of后面接比较对象, 属同类。e.g.

Julia is the quietest of these girls.朱丽娅是这些女孩中最文静的一个。

This movie theater is the best in our town.这家影院是我们镇上最好的。

3.表示“ (在众多当中) 最……之一”, 常用“one of the+形容词最高级+复数名词”结构。例如:

Beijing is one of the biggest cities in China. 北京是中国最大的城市之一。

4.最高级前既用the, 也用序数词, 其结构为:“the+序数词+最高级”, 表示“第几个最……”。例如:

The Yellow River is the second longest river in China. 黄河是中国第二长河。

可数名词PK不可数名词

1. 可数名词前可以加不定冠词a/an或数词等限定词直接修饰, 不可数名词不能用a/an或数词等修饰。

2. 不可数名词前可用much (很多) , a little (一点) , some (一些) , any (一些) , a lot of/lots of或“数词+表示数量的可数名词+of”结构修饰。

3. 对可数名词提问时用how many, 对不可数名词提问用how much, 但对不可数名词前表示数量名词中的修饰语提问时则用“how many+ 复数量词+of”。

4. 有些词既是可数的, 又是不可数的, 如:当chicken意为“鸡”时是可数的, 意为“鸡肉”则是不可数的。

一般过去时

1. 表示在过去时间段发生过某事要用一般过去时, 而不能用一般现在时。例如:

2. 在含有行为动词的一般过去时的句子变为否定句或疑问句时, 要借助助动词did。例如:

When were you call me for the DVD machine? (×)

When did you call me for the DVD machine? (√)

3. 英语中有些表示过去的词 (组) , 如yesterday, last week, a moment ago等, 其前不能加任何介词。例如:

He came to China on yesterday afternoon. (×)

He came to China yesterday afternoon. (√)

现在进行时的特殊用法

1. 表示感情色彩。现在进行时可与always等副词连用, 表示经常、反复或习惯性的动作, 表达说话者的一种赞扬、责怪、不满的语气。如:

Lu Shan is always helping others. 陆杉总是帮助别人。

2. 表示将来。go, come, leave, start等少数动词, 常用现在进行时表示按计划、安排将要进行的动作。例如:

Mr Green is coming! 格林先生要来了!

3. 表示渐变的过程。get, become, grow, turn等连系动词的现在进行时表示一个变化过程, 比一般现在时更形象逼真。例如:

It’s getting warm. 天渐渐暖起来了。

4. 表示刚刚发生过的动作。在口语中, 可用tell, say, talk等动词的现在进行时表示刚刚发生过的动作。例如:

I don’t know what you’re saying.我不知道你在说什么?

复合不定代词和复合不定副词

1. 复合不定代词及复合不定副词。

2. 复合不定代词作主语时, 谓语动词要用单数形式。

例:Everyone knows me here.

3. 形容词修饰复合不定代词时形容词放后。

例如:There is something new in today’s newspaper.

4.any以及any构成的词多用于否定句、疑问句、if条件句和含否定词的句子中。

例如:If you don’t want anything, please let me know.

He is too busy to see anyone come in.

The boy is too heavy for anyone to carry.

Anyone doesn’t know me here. 应改为No one knows me here.

注意:

① any以及any构成的词在否定句中不可作主语而应换成相应的代 (副) 词

②any以及any构成的词在否定句中为完全否定

not…any=no

not…any one/anybody=none/nobody

not…anything=nothing

not…anywhere=nowhere

例如:I can’t see anything in the room.=I can see nothing in the room.

③any以及any构成的词也可用于肯定句

any任何一个

any one=anybody任何人

anything任何事物

例如:He is taller than anyone else in my class.

5.every以及every构成的词在否定句中为不完全否定

例如:He knows everything.否定句:He knows nothing.他什么都不懂。

而不能改成He doesn’t know everything.他不是事事都懂 (否一半) 。

6.表示人的复合不定代词用人称代词、物主代词替换时一般用复数形式, 有时又可用单数, 这要根据上下文来决定。

① If anyone invites you, you have to meet them on time. (前面用单数, 后面是宾格复数them)

拓展思维:人称代词有主格宾格之分, 主格有I, he, she, it, you, we, they, 宾格有me, him, her, it, you, us, them。主格的要放在主语位置, 宾格的要放在宾格位置。主语位置一般放在句首, 如:I am a teacher. 在英语中, 宾格有两个位置, 一个在动词后跟宾格, 注意不是所有的动词都需要跟宾语。另一个在介词后跟宾语。

例如:I give him a book. 这里的give是动词, him是give的宾语 (宾语的作用是使谓语所表达的意思更加完整和清楚) , 因为him的位置是宾语, 所以如果在这个位置上用的是人称代词, 就得用宾格, 而不能用主格的he。

②No one knows me here, do they? (前面用单数, 后面是复数they)

③Everyone is doing their homework now.

④ If anyone calls me, tell him / her to call back after 8:00.

7.none做主语时, 谓语可单可复。

例如:None of us go / goes to school by bus.

None of us is a cook.

八年级下重点作文 篇7

【词条1. alone】

例句:I don’t like living alone.

我不喜欢独处。

点拨:alone既可用作形容词,也可用作副词,意为“单独的(地)”、“独立的(地)”。用作形容词时,习惯上只作表语,强调的是没有另外的人在场的“单独”,并不指心灵上的孤独。例如:

Her parents were dead and she was alone. 她父母死了,她单独一个人。

The old man lives alone.

那位老人独自生活。

拓展:与alone意义相近的词是lonely。lonely意为“孤独的”、“寂寞的”,有较浓厚的感情色彩,指因缺少朋友、同情、友谊时产生的一种悲伤和忧郁的感情。它是一个形容词,在句中作表语或定语。用作定语时,意为“荒凉偏僻”,一般多修饰表示地点的名词。例如:

Was there someone else on this lonely island? 在这个荒岛上还有别的人吗?

I’m alone, but I don’t feel lonely.

我独自一个人,但不感到孤单。

【词条2. able】

例句:At the weekends, I’ll be able to dress more casually. 周末的时候我会穿得更随意一些。

点拨:able是形容词,意为“能;能够”,常用于be able to 结构。例如:

She is able to dance. 她会跳舞。

I shall be able to speak English well.

我的英语讲得很好。

拓展:can和be able to二者都可以表示“能”、“会”,当表示现在和过去“力所能及”时,一般可以相互换用。例如:

I can/am able to speak a little English now. 我现在会说一些英语。

He was able to/could swim when he was eight years old. 他八岁就会游泳。

但它们也有区别:

1)be able to的过去时还可以表示一种“经过努力做到了”的意思,can的过去时则没有这种意义。例如:

He started late, but he was able to catch the eight o’clock train. 他出发晚了,但他努了一把力,还是赶上了八点钟的火车。

2)can通常只用于一般现在时和一般过去时,而be able to可用于各种时态。例如:

You will be able to learn another foreign language in two years. 两年后你将能够学会另一门外语。

He hasn’t been able to go to office for a month. 他已经一个月没能上班了。

3)be able to可用于不定式的后面,而can则不行。例如:

I hope to be able to go fishing with you.

我希望能和你一起去钓鱼。

4)在表示猜测时,只能用can, 而不能用be able to。例如:

Mr. Green can’t be at home now.

现在格林先生不可能在家。

【词条3. dress】

例句:She washed, dressed and went out.

她洗完脸穿好衣服就出去了。

点拨:dress可指穿衣服的动作,用作不及物动词时,表示“穿好衣服”,用作及物动词时,后面要接“人”,不接“衣服”,表示“给某人穿衣服”。例如:

My daughter is old enough to dress herself. 我的女儿长大了,可以自己穿衣服了。

Could you dress the child for me?

你能不能替我给孩子穿上衣服?

dress也可以指“穿着”衣服的状态。例如:

She always dresses in red.

她总是穿红色的衣服。

He dresses well. 他穿得体面。

拓展:与dress意义相近的还有:put on,wear和in。三者均有“穿、戴”之意,但用法不同:

put on意为“穿上、戴上”,指穿戴的动作,强调从没穿戴到穿上、戴上这一动作的转变。例如:

This is your new shirt. Put it on, please.

这是你的新衬衣。请把它穿上。

wear意为“穿着、戴着”,强调穿戴的状态。例如:

She is wearing a red coat today.

今天她穿着一件红色的上衣。

in是介词,也可以用来表示“穿着、戴着”,be in 相当于be wearing。“in+表示颜色的词”可以用来表示穿某种颜色的衣服。例如:

The girl in the hat is Lucy.

戴着帽子的女孩是露西。

She is in white today.

今天她穿着白色的衣服。

【词条4. such】

例句:People would not like to do such jobs and would get bored. 人类不喜欢这样的工作,而且很容易觉得乏味。

点拨:such是形容词,意为“这样的;这种”,用来修饰名词。例如:

Don’t be in such a hurry. 不要如此匆忙。

It was such a hot day. 这么热的一天。

拓展:与such意义相近的词是so, 但so是副词,用来修饰形容词和副词。例如:

She is so young. 她这么年轻。

He works so hard. 他工作那么努力。

She is such a good girl. 她真是个好女孩。

请看记忆口诀:

名前such,形、副so①,多多少少(many, much, few, little)仍用so②。

注:①名词前面要用such。so后常跟形容词或副词。例如:

He sings so well. 他唱歌唱得那么好。

They are such good teachers.

他们是多么好的老师。

如such后接单数名词,a(an)应放在such之后,不可放在前面。例如:

I have never seen such an interesting film. 我从未看过这么有趣的电影。

②如名词前有 many, much, few, little修饰,应用so,不用such。例如:

She has so many books. 她有这么多书。

There is so little time that we can’t finish the work on time. 时间那么少,我们不能按时完成那项工作。

特别提醒:当little不表示“少”的意思时,其前仍用such。例如:

They are such little children that they can’t do anything. 他们是小孩子,什么也不能做。

另外;“such a/an+形容词+单数名词”可以转换成:“so+形容词+a/an+单数名词”。例如:

This is such an interesting story that we all want to listen to it.=This is so interesting a story that we all want to listen to it.

请注意:so可用作代词,用在诸如:I hope so.(我希望如此。);I don’t think so.(我不这样想。)等等这类句型中。such不能用于此类句型中。例如:

——Will it be fine tomorrow?

明天会是晴天吗?

——I hope so. 我希望如此。

【词条1. either】

例句:I don’t like swimming, either.

点拨:either表示“也”的意思时只用于否定句中,置于句尾,且前面常有逗号分开。例如:

你不认识他,我也不认识他。

If you don’t go there, I won’t, either.

如果你不去那里,我也不去。

拓展:与either意义相近的还有also, too和as well。三者都有“也”的意思,但用法有所不同:

too用于肯定句,位于句尾,其前常用逗号分开。例如:

as well 在口语中用得很多,用法和too完全一样,可以互换,通常位于句末。例如:

【词条2. except】

例句:We all went to the park except Li Ming last Sunday. 上星期天,除了李明外,我们都去公园了。

We go to school every day except weekends. 除周末外我们每天上学。

拓展:与except意义相近的还有besides和except for,两者都有“除外”的含义,但其用法有较大区别

besides 意为“除……外,还有……”,“包括”,相当于with或plus(加), 表示一种累加关系。例如:

There are three more visitors besides me. 除了我以外,还有三名参观者。

except for与except的用法有所不同,except主要用来谈论同类东西,而except for则用来谈论不同类东西,在说明情况后在细节上加以修正。例如:

We go there every day except Sunday.

除星期天外我们每天都去那儿。(every day 和Sunday都表示时间)

她直到十点钟才离开。

We’ll wait until he comes back.

我们将一直等到他回来。

拓展:与until意义相近的还有till。两者在一般情况下可以换用,但是在下面两种情况下只能用until而不能用till。

1)用于句首时只能用until, 不能用till。例如:

Until you told me I had no idea of it.

在你告诉我之前,我对此事一无所知。

2)在以not开头的短语或从句里只能用until, 而不能用till。例如:

Not until eleven o’clock did we get home.

我们直到十一点才回到家。

Not until a few days ago did I know her name. 直到几天前我才知道她的名字。

特别提醒:till/until只用于指时间,不用于指空间或距离等其他概念。例如:

误:He walked on and on until the end .of the road.

正:He walked on and on until he got .to the end of the road.

正:He walked on and on to the end of .the road.

【词条4. fit】

例句:This sweater fits you well.

【词条5. send】
