3、點難點講解1_neither too wet nor too dry.既不要太潮濕也不要太枯燥。both 和neither1)both表示“兩者都”，即指兩個人或物，是復數(shù)概念；neither“兩這種無一”，也指人或物，然而是單數(shù)概念。因此，both修飾復數(shù)名詞，謂語用復數(shù)形式；neither修飾單數(shù)名詞，謂語用單數(shù)形式。如：Both answers are right.兩個答案都對。Neither answer is right.兩個答案無一是對的。第二句是第一句的全否認形式。它的不完全否認形式是這樣的，Both answers are not right.兩個答案并不都對。I like b

4、oth of them.他們兩個我都喜歡。I like neither of them.他們兩個我都不喜歡。假如數(shù)量是三個或三個以上，那么肯定句用all,否認句用none。如：All of them are interested in it.他們對此都感性趣。None of them are(is) interested in it.他們對此都不感性趣。2bothand和neithernor可以連接兩個并列成分，即兩個主語，謂語，賓語或其他并列成份。如：She can both sing and dance.她既會唱歌又會跳舞。She can neither sing nor dance.她既

5、不會唱歌又不會跳舞。Both Tom and John are from Britain.Tom 和John都是英國人。Neither Tom nor John is from Britain.Tom和John 都不是英國人。bothand連接兩個主語時，后面謂語用復數(shù)。而neithernor連接兩個主語時，后面 謂語必須與nor后面的主語在數(shù)上保持一致。如：Neither Jack nor his parents are interested in the girl. Jack和他的父母對那個女孩都不感興趣。2happen to sb./sth. 表示某人或某件事情發(fā)生了什么情況。很多時候表

6、示一種偶爾性。happen的主語一般是疑問代詞what ，不定代詞something, anything,nothing,以及某些表示消極意義的名詞。happen是不及物動詞，不能用于被動語態(tài)。Happen總是和介詞to搭配。如：1)What has happened to Mary? She isnt here yet. Mary出了什么事？她如今還沒到。2If anything happens to the machine,please let me know. 假如機器出了什么缺點，請通知我。3The accident happened to him at three this afte

7、rnoon. 他出事是在今天下午三點半。3 about a third was 大約三分之一是. 分數(shù)的表達法分子用基數(shù)詞，分母用序數(shù)詞。假如分子是二或二以上的數(shù)，分母加-s.如：one-third 三分之一two-thirds 三分之二分數(shù)作主語，謂語的單復數(shù)取決于它所代表的量是單數(shù)還是復數(shù)。如：Three-fourths(Three quarters)of the students of our school are boys. 我們學校四分之三的學生是男生。Three quarters of the work has been done. 工作的四分之三已經(jīng)完成。4hundred和hun

8、dreds ofhundred前面可以用表示詳細概念的數(shù)詞來修飾。而hundreds of表示“多”， “數(shù)以計”，前面不可一家表示詳細概念的數(shù)詞。如：There are two hundred students in our grade.我們年級右二百個學生。Several millions of trees are planted in our country every year. 我國每年將種植好幾百萬棵樹。5Stopfrom doingstop sb./sth.from doing sth.是“阻止不作某事”，介詞from可以省略。如：We must stop him (from)d

9、oing such a foolish thing. 我們必須阻止他不讓他作這樣的蠢事。They tried to stop such a thing (from)happening. 他們向阻止這樣的事情發(fā)生。6stop to do和stop doingstop to do的意思是“停下來做事情”，不定式做狀語。stop doing的意思是“停頓做事情”。如：They stopped to talk to me.他們停下來和我講話。Stop running about! 不要亂跑。7the more, the better越多越好。前一分句表示假設，條件，時間等，后一分句表示結果。如； Th

10、e more you read,the more you will get.你讀的越多，得到的也就越多。The farther he walked, the stranger he felt.她越往前走，越感到奇怪。8thanks to “多虧了”,“由于幫助“。如：Thanks to the English language, we can learn a lot from English-speaking countries. 由于英語這門語言的幫助，我們可以向說英語的國家學到許多東西。Ive passed the e_ams thanks to my teachers.多虧了我的教師，我通過了這次考試。9不定式作定語1I have a lot to do today.我今天有許多事情要做。a lot是do的邏輯賓語2I have three letters to write this evening.今晚我有三封信要寫。3
