be known as...
be known as作為……而出名
He is known as a fair judge.他作為一名公正的法官而出名。
同義詞：be famous as
辨析：be known for意思是“因……而出名”，相當(dāng)于be famous for。
He was known for his frankness.他因坦誠(chéng)而出名。
be known to意思是“……所熟知的”。
As is known to all, the earth is round.
正如大家所熟知的那樣，地球是圓的。
yet用法
在現(xiàn)在完成時(shí)的句子中，already常用于肯定句，yet常用于否定句和疑問(wèn)句，但yet還有其他用法。
1. 用于否定句中，意思是“還、尚、迄今、到那時(shí)”。例如：
He is not yet here. 他還未到。
At three o’clock they had not yet decided whether to play basketball or not.
三點(diǎn)鐘時(shí)他們尚未決定是否去打籃球。
2. 用于疑問(wèn)句中，意思是“已經(jīng)”。例如：
Is everything ready yet ? 一切都準(zhǔn)備好了嗎？
3. 與比較級(jí)連用，意思是“更”。例如：
You must work yet harder. 你還需更努力地工作。
4. 與once , again , another 連用，意思是“再”。例如：
He has made yet another mistake.
他又犯了一個(gè)錯(cuò)誤。
5. 用于肯定句中，意思是“仍然、還得”。例如：
She is yet a child. 她還是個(gè)孩子。
6. 用作并列連詞時(shí)，意思是“然而、可是”。例如：
He studied hard yet he failed.
他學(xué)習(xí)努力，可是考試仍未及格
still：yet 辨析
1a. 一般說(shuō)來(lái)，這兩個(gè)副詞幾乎可以通用，只是兩者在句中的詞序稍有不同
比較：I’ve still a few more pages to read. 我尚有幾頁(yè)書(shū)要讀。
I’ve a few more pages to read yet. 我尚有幾頁(yè)書(shū)要讀。
We have exported a lot of goods，but we must export still more.
我們已出口了許多貨物，但仍須再多出口一些。
We have exported a lot of goods，but we must export more yet.
我們已出口了許多貨物，但仍須再多出口一些。
1b. 兩者的情態(tài)色彩和語(yǔ)氣強(qiáng)弱不一樣。試舉例來(lái)說(shuō)明。
比較：Is Teddy still here？丹迪仍在這里嗎？（仿佛說(shuō)，他曾在這里，但不知他走了沒(méi)有，所以這一句等于“Hasn't he left？”的意思。）
Is Teddy here yet？丹迪還沒(méi)有來(lái)嗎？（仿佛說(shuō)，我希望他來(lái)，但不知他來(lái)了沒(méi)有，所以這一句等于“Has he arrived？” 的意思。）
Is Jane still not here？珍妮還沒(méi)有到嗎？（不愉快的心情較強(qiáng)）
Isn’t Jane here yet？珍妮還沒(méi)有到嗎？（不愉快的心情較弱）
take與bring都有“帶”，“拿”的意思。take與bring實(shí)際上是一對(duì)反義動(dòng)詞。take的意思是“拿走”，“帶走”，指把某人或某物從說(shuō)話人所在地帶往別處。例如：
Take him to hospital at once, please.
請(qǐng)馬上帶他去醫(yī)院。
bring指“帶來(lái)”，“拿來(lái)”，指把某人或某物從別處帶到說(shuō)話人身邊來(lái)。例如：
Eddie brings me some books.
埃迪給我?guī)?lái)了幾本書(shū)。
bring to 帶來(lái)好東西 bring on 帶來(lái)壞東西
Work brings happiness to us.
Laziness brings misfortunes on us.
bring與take在動(dòng)作方向上的區(qū)別相當(dāng)于come 與go。請(qǐng)?bào)w會(huì)這個(gè)句子：Take this coat away and bring me mine. 把這件外衣拿走，把我的外衣拿來(lái)。
also，too
這兩個(gè)詞都是副詞，又都表示“也是”的意思，但在修辭意味和使用場(chǎng)合上有所不同。它們的區(qū)別如下：
（一）一般說(shuō)來(lái)，also用于比較正式（formal）的場(chǎng)合，語(yǔ)氣比too莊重； too是慣熟（familiar）的用語(yǔ)，使用范圍較廣。
（二）also在句中的位置要緊靠動(dòng)詞； too在句中的位置比較靈活，有時(shí)插入句中，前后用逗號(hào)分開(kāi)，有時(shí)放在句末。
（三）too只能用在肯定句中，不可用于否定句內(nèi)。either只能用于否定句；also即可以用在肯定句中，又可以用在否定句中。
下面請(qǐng)看例句：
Reading books is learning，but practice is also learning。
讀書(shū)是學(xué)習(xí)，實(shí)踐也是學(xué)習(xí)。
We have not heard such a thing. Also，we have never seen such a scene.
我們沒(méi)有聽(tīng)見(jiàn)過(guò)這種事情，我們也從來(lái)沒(méi)有見(jiàn)過(guò)這種場(chǎng)面。
請(qǐng)注意，一般說(shuō)來(lái)，also在句中的位置應(yīng)緊靠動(dòng)詞，但有時(shí)為了強(qiáng)調(diào)其意，也可以將它放在句首或句末。
Mary, too, can play the piano.
瑪麗也會(huì)彈鋼琴。
Could you speak Japanese？-Yes，and Spanish too.
您會(huì)說(shuō)日語(yǔ)嗎？--會(huì)的，還會(huì)說(shuō)西班牙語(yǔ)哩。
also雖然和too同義，但前者大都用于書(shū)面語(yǔ)，后者大都用于口語(yǔ)。例：
The lady washed the children and also gave them dinner. （書(shū)面語(yǔ)）
The lady washed the children and gave them dinner too. （口語(yǔ)）
在口語(yǔ)中，too還可以用 as well代替。
as well as，as well
這一對(duì)短語(yǔ)僅差一字之微，意義相近，故很易引起混淆。
作為習(xí)語(yǔ)用作介詞時(shí)，as well as的涵義是“還有”、“不但…而且…”。值得注意的是，在A as well as B的結(jié)構(gòu)里，語(yǔ)意的重點(diǎn)在 A，不在 B。因此，“He can speak Spanish as well as English. ”的譯文應(yīng)該是：“他不但會(huì)說(shuō)英語(yǔ)，而且會(huì)講西班牙語(yǔ)”，決不能譯作：“他不但會(huì)說(shuō)西班牙語(yǔ)，而且會(huì)講英語(yǔ)”。如果這樣翻譯，就是本末倒置了。as well as和 not only… but also…同義，但前者的語(yǔ)意重點(diǎn)和后者的語(yǔ)意重點(diǎn)恰好顛倒。
如果 as well as用作連詞引出比較從句，其義為“和…一樣好”。因此，“He speaks Spanish as well as English. ”應(yīng)譯作：“他說(shuō)西班牙語(yǔ)像說(shuō)英語(yǔ)一樣好”。語(yǔ)意的重點(diǎn)依舊在前部，不在后半部。
make…from make…of make…into make up
They make wine from grapes.
This big box is made of wood.
They make milk into butter and cheese.
A car is made up of many different parts.
show
show sb. sth. show sth. to sb.
Show me what you have in your bag.
He showed me his pictures.
1. 一般現(xiàn)在時(shí)(the Simple Present Tense)
1) 敘述公認(rèn)的事實(shí)和真理，沒(méi)有時(shí)間性，任何時(shí)候都是如此。如：
The earth is round.
Wealth doesn't always bring happiness to us.
2) 敘述現(xiàn)階段平日習(xí)慣或日常的行為活動(dòng)。在這種句子里常有表示習(xí)慣性的副詞、副詞短語(yǔ)或從句。有：often, usually, sometimes, always, never, seldom, every day, once a year, on Sundays等，或從句when…,as soon as…等，如：
Do you go to school on Sundays?
How often does he go to the cinema?
As soon as he arrives, I'll tell him the truth.

If it rains tomorrow , I’m going to stay at home.
I won’t go there unless he invites me .
但是，當(dāng)if, when引導(dǎo)賓語(yǔ)從句時(shí)，表示將來(lái)時(shí)間須用將來(lái)時(shí)。如：
I don’t know he will come.
I wonder if it will rain tomorrow.
5) 代替現(xiàn)在時(shí)行時(shí)：在“Here comes…”、“There goes …”的倒裝結(jié)構(gòu)中，用一般現(xiàn)在代替進(jìn)行時(shí)。如：

A Golden Watch
Mr Mike was a young man. He was not very rich. One day he went into a watch shop to buy a nice-looking watch for his girl friend, Rose. He fixed his eyes on a nice golden watch, and decided to buy it. The shop assistant took the watch out, and asked for three hundred pounds for it. Just then, a boy of about fifteen suddenly rushed over and grasped the watch from the assistant's hand. The assistant hurried out to catch the boy. But it was too late, the boy had disappeared among the street very quickly.
On the way home, Mike met the boy, who would sell him the gold watch for only one hundred pounds. “The boy didn't know that I saw him stealing the watch from the shop. And he asked for much less money than that in the shop.” Mike thought to himself. So he paid the boy and took the watch home.
The next day, Mike gave the golden watch to Rose, and told her all about the watch. Rose looked at the watch for a while, then, laughed loudly, “You are really a fool!" she said, "This watch isn't worth 100 pounds at all. The assistant and the boy must have planned the whole thing together!”
