。1)本句中的in order to是一個(gè)固定搭配的短語,意思是“為了”,后接動(dòng)詞原形構(gòu)成不定式結(jié)構(gòu)在句子中作目的狀語,否定形式是在to前面加not。in order to可以和so as to 互換,但后者不能放在句首。例如:
In order not to be late, you should go now.
為了不遲到,你現(xiàn)在應(yīng)該走。
。2)in order to+動(dòng)詞原形和so as to+動(dòng)詞原形可以轉(zhuǎn)換成in order that+從句和so that+從句。例如:
He did anything in order to make money.
= He did anything in order that he could make money.
為了賺錢,他什么都做。
Please go in quietly so as not to wake the baby.
=Please go in quietly so that we won’t wake the baby.
請(qǐng)不聲不響地進(jìn)去以免弄醒孩子。
3. For one week, she did not do any housework and neither did I. “neither +be動(dòng)詞/助動(dòng)詞/情態(tài)動(dòng)詞 + 主語”表示“……也不”,指后者與前者具有相同的情況,但是表示的是否定意義的相同。相當(dāng)于一個(gè)主謂倒裝的否定句。neither 此處意為“也不”,是副詞。例如:
Mary doesn’t like singing. Neither do I.
瑪麗不喜歡唱歌,我也不喜歡。(我和Mary 有相同的情況,前句是否定句,下文用neither開頭,主謂倒裝)
如果上文是肯定句,下文表示與上文有相同情況時(shí),用“so+ be動(dòng)詞/助動(dòng)詞/情態(tài)動(dòng)詞 + 主語”。例如:
Mary likes singing. So do I.
瑪麗喜歡唱歌。我也喜歡。(我和Mary有相同情況,前句是肯定句,下文用so開頭,主謂倒裝)
【拓展】
當(dāng)表示對(duì)上文所講內(nèi)容的贊同時(shí),可以用“so + 主語 + be動(dòng)詞/助動(dòng)詞/情態(tài)動(dòng)詞”或者“neither + 主語 + be動(dòng)詞/助動(dòng)詞/情態(tài)動(dòng)詞”來表示。前者用于肯定句,后者用于否定句。例如:
Mary plays the piano well. So she does.
瑪麗鋼琴彈得很好。她確實(shí)彈得好。(表示對(duì)上文所講內(nèi)容的贊同,前句是肯定句,下文用so開頭,主謂不倒裝)
Mary doesn’t play the piano well. Neither she does.
瑪麗鋼琴彈的不好。她確實(shí)彈得不好。(表示對(duì)上文內(nèi)容的贊同,前句是否定句,下文用neither開頭,主謂不倒裝)
4. And she won’t be happy if she sees this mess.
。1)本句中if后面的部分是這個(gè)句子中的條件狀語從句。在以when,after,as soon as等引導(dǎo)的時(shí)間狀語從句以及以if,unless等引導(dǎo)的條件狀語從句中,如果主句是一般將來時(shí),從句則用一般現(xiàn)在時(shí)表將來。例如:
I’ll tell her the good news when she comes back.
當(dāng)她回來的時(shí)候,我將把這個(gè)好消息告訴她。
If it doesn’t rain, he will come here on time.
如果不下雨,他會(huì)按時(shí)來這兒的。
常見的“主將從現(xiàn)”有以下三種情況:
1)條件狀語從句的主句是一般將來時(shí),那么從句常常用一般現(xiàn)在時(shí)。例如:
When I grow up, I’ll be a nurse and look after patients. 我長(zhǎng)大后要當(dāng)一名護(hù)士,照顧病人。
2)如果主句是祈使句,那么從句通常要用一般現(xiàn)在時(shí)。 例如:
Don’t laugh at me when I make a mistake. 我犯錯(cuò)誤的時(shí)候不要笑話我。
3)如果主句是含有情態(tài)動(dòng)詞的一般現(xiàn)在時(shí),根據(jù)需要從句多用一般現(xiàn)在時(shí)。例如:
You should be quiet when you are in the reading room. 在閱覽室時(shí)應(yīng)保持安靜。
5. I do not understand why some parents make their kids help with housework and chores at home.
本句中的make作使役動(dòng)詞,意為“使……;讓……”講時(shí),常構(gòu)成make sb. do sth. 意為“使/讓某人做某事”,類似的動(dòng)詞還有l(wèi)et,have等。例如:
The boss made them work for long time. 老板讓他們長(zhǎng)時(shí)間工作。
They made us forget past. 他們使我們忘記了過去。
Their boss often let them work long hours every day. 他們老板經(jīng)常讓他們每天工作很長(zhǎng)時(shí)間。
【拓展】
make作使役動(dòng)詞,還可以構(gòu)成:make + 賓語(sb./sth.) + 形容詞/名詞(作賓補(bǔ)),即make sb. / sth. + adj./n.。例如:
What he said makes us happy. 他所說的話使我們很高興。
We made John our monitor. 我們選約翰當(dāng)班長(zhǎng)。
