                                        Lesson 74 现在进行时和一般现在时
                                        Lesson 75不定式
                                        不定式:是一种非谓语动词,时间上表示将要
                                        ① 做主语
                                        It is important to do sth.
                                        ② 做宾语
                                        want to do
                                        ③ 做宾补
                                        allow/expect sb. to do sth.
                                        ④ 做定语(放在被修饰词之后)
                                        anything to do
                                        ⑤ 做状语:目的状语
                                        ⑥ 做表语
                                        Lesson 75-82 一般过去式,现在完成时和现在完成进行时的关键句型
                                        Lesson 83-84状从中主谓的省略和it作先行宾语
                                        Though a little suspicious this time, the policeman gave him the same answer.
                                        这是一个让步状语从句。如果从句的主语和主句的相同而谓语带系动词be,则主语+be 可省略;但原
                                        因状语从句的省略形式要带分词being:
                                        If possible, please let me know by this evening.
                                        如果可能的话,请今晚以前告诉我。
                                        Being worried about his child, he walked up and down in the room.
                                        [Special Difficulties]
                                        it 作先行宾语
                                        在主语+动词+宾语+宾语补足语的句型?#26657;?#24120;用it 作先行宾语,真正的宾语为后面的动词不定式或从
                                        句:
                                        People are going to find it difficult to get to work.
                                        常用这种结构的动词?#26657;篺ind,think,consider,feel,make,keep 等:
                                        She felt it right for them to arrest the thief.
                                        They consider it impossible to finish the work in three days.
                                        Lesson 85-89 由That引导的定语从句
                                        Lesson 90
                                        [Special Difficulties]
                                        被看作整体的用and连接的两个名词
                                        当主语是and连接的两个名词时,谓语通常用?#35789;?#24418;式:
                                        An umbrella and a suitcase are still needed.
                                        ?#34892;?#21517;词由于经常在一起连用,就把它们看成一个整体(或一个单位),因而成了一种复合名词。它们
                                        不仅有固定的词序,且后面的谓语动词通常要用单数形式。这类复合名词?#26657;篵acon and eggs(咸肉和鸡蛋),bread and butter(面包和黄油),cheese and wine(奶酷和?#21688;?#37202;),fish and chips(鱼和油炸土豆片),a knife and fork(一副刀叉),sausage(s) and mash(香肠和土豆泥)。通常被作为单数看待的有一道菜和一套东西。
                                        Fish and chips is a popular meal in Britain.
                                        如果把两个名词看成是分开的东西,动词就要用?#35789;?br /> Fish and chips make a good meal.
                                        Lesson 91-96
                                        由when,where等特殊疑问词引导的定语从句及常用句型的学习
