7、g got so angry that she ran after them.这句使用了sothat结构，与suchthat相比：so后面是跟形容词和副词；而such后面是跟名词。suchthat与sothat都可以用来引导结果状语从句，意为“如此以致”。suchthat的句型结构可分为以下三种：such+a（n）（+adj.）+单数可数名词+that从句。如：She is such a good teacher that all of us love her.such（+adj.）+复数可数名词+that从句。如：They are such interesting books that I

8、want to read them once more.such（adj.）+不可数名词+that从句。如：It was such bad weather that I had to stay at home.（2）so是副词，与形容词或副词连用，其结构是：so+adj.（adv.）+that从句。如：He ran so fast that I couldnt catch up with him.I am so sleepy that I can hardly keep my eyes open.注意：当名词前面有many，much，few，little等表示数量多少的限定词时，应该用so，而

9、不能用such。如：只有如此少的观众，以至于王心凌都不想来了。There were so few audience that Wang Xinling didnt want to come.当单数名词前有形容词时，既可用so，也可用such，但不定冠词的位置却有所不同。如：这是一次很重要的会议，你一定要参加。This is such an important meeting that you should attend it.=This is so important a meeting that you should attend it.5、She was soon out of breat

10、h,but she continued to run.out of breath 上气不接下气Tom ran to the shop to get some salt for his mother.When he reached there,he was quite out of breath.continued to do sth.不同事 continue doing sth.同件事 1）catch up with sb.追上,赶上(强调结果)2）go through搜查，翻看(速度较快的看)She went through her bag,but she couldnt find her

12、ire doing sth.需要被做，后面接的动名词有被动的含义。相当于need to be done 比如：The car needs washing.mend是表示“修修补补，小修小补”，常用于修补打破、撕破的东西或衣物等。repair也是表示“修理”，不过repair是指修理好损坏的、用旧的东西，或是出故障的机器。同fix。比如：Our piano is being repaired.Ill mend the shirt.总之，repair比mend正式。8、The strap needs mending,said Mrs.Sterling later,but they did not

14、以做主语、宾语、介词宾语等（见a）Washing the car made me tired.（主语）Prices will continue to rising.（宾语）I am very keen on cycling.（介宾）2、动名词还可以用于“动词+介词”之后（见b）to后跟动名词的有（此时to为介词）look forward to doing sth.期盼做某事 I am looking forward to seeing him tomorrow.be accustomed to doing sth.习惯于做某事 I am accustomed to getting up ear

17、d of be good at do well in等 3、在start，begin，continue等后面，既可以用不定式又可以用动名词，区别不大：见C I began to learn/learning English two years ago.一般来说，begin to do和begin doing可以互换，但在以下三种情况下，用to do：1.主语不是指人，而是it等。如：It began to rain.2.begin后接表示心理活动的词。如：begin to know，believe，wonder，think等。3.begin本身是ing形式，为避免重复后接to do。即，beg

18、inning to do doing 一般有正在做的意思 to do一般有正准备做的意思.to do sth 意思是指“开始去做某事”，有“潜在的可能”；.doing sth 意思是指“开始做某事”，有“实际进行”的意思。当涉及到多次活动时使用.doing更为恰当。4、在hate、love，like，prefer等动词后，用不定式和动名词意义有所区别。见d hate,love,like+doing sth.表示一种习惯(always)hate,love,like+to do sth.表示某一次性的行为(now)would love/like to do sth.表示想要类似的词还有rememb

19、er to do doing 没做/做了 forget to do doing 没做/做了 regret to do doing 没做/做了stop to do doing try to do doing mean to do doing 打算干/意味着 5、在need，want之后，动名词形式具有被动的含义，相当于被动的不定式：见e 如果以物体做主语，可以直接加动词-ing，表达被动的含义 My shirt is torn.It needs mending.我的衬衫撕破了,需要缝补.Those windows are dirty.They want washing.那些窗户很脏,需要洗刷Fi

20、nish ExerciseB on Page 200【Special Difficulties】catch and run catch主要意思是“抓住、捉住、逮住”，但有时可以表示“（及时）赶上、追上”等：He ran quickly to catch the last bus home.When she caught up with them,she saw that they were going through the contents of the bag.run的本意是“跑”，后面加上不同的词可以表达“追赶，逃跑”等多种含义：She has run off with all his money.The man ran away with her bag.
