If you go to the party, youll have a great time. (1) 本句是if引导的条件状语从句，主句用一般将来时，从句用一般现在时代替一般将来时。例如：Ifyoufailintheexam, youwilllethimdown.如果你考试不及格，你会让他失望
4、的。 (2) 在if引导的条件状语从句中，if条件句位置灵活，可直接放在主句后面，若if条件句放句首，从句后面要加逗号，和主句隔开。 If you ask him，he will help you. = He will help you if you ask him. 如果你请他帮忙，他会帮你的。口诀：if条件句不一般，几个要点记心间；条件句，放在前，逗号要放句中间。 条件句表可能，主句多用将来时。2. because theyll be too lazy to cook. tooto意为“太而不能”。它在结构形式上是肯定的，但意义上却表示否定含义，所以动词不定式符号to前不能再加not，只接
5、动词原形即可，too后接形容词或副词原形。例如： The book is too difficult to understand. 这本书难于理解。【拓展】 (1) 在tooto句型中，当动词不定式的动词是不及物动词，其后所跟的介词不能省略。例如： The room is too small to live in. 这房间太小了不能住。 (2) 在tooto句型中，当动词不定式的宾语实际上就是这个句子的主语时，动词不定式后面不能再加代词作宾语。例如： The question is too difficult to answer. 这个问题太难了，无法回答。 (3) 在tooto句型中，当动词
6、不定式能确切说明动作执行者时，可以在动词不定式前面加上逻辑主语，即for sb.形式。例如： The box is too heavy for him to carry. 箱子太沉了，他搬不动。 (4) 含tooto的句子可以改写成sothat句型，意为“如此以至于”。例如： He is too old to do hard work. = He is so old that he cant do hard work. 他年纪太大而不能干重活。 (5) 含tooto的句子也可以用“not + 形容词/副词 + enough to do sth.”句型来替换，但注意要用原句中形容词或副词的反义词
7、。例如： He is too old to do hard work. = He is not young enough to do hard work. 他年纪大了，不能做重活。3. Sometimes they have problems with their school work have problems with sth. 意为“在某方面有困难/有问题”。例如： He has some problems with his ears. 他的耳朵有些问题。 【拓展】have problem doing sth. = have problem (in) doing sth.意为“做某事遇
8、到困难或麻烦”，也可用have trouble/difficulty (in) doing sth.或with sth. 例如： They had problems in getting here. 他们到达这里遇到很多困难。4. I think talking to someone helps a lot. talking to someone是动名词短语，在句子中作从句的主语。动名词是动词的一种形式，具有名词特点，在句子中可以充当主语、表语或宾语。(1) 作主语，动名词作主语，谓语动词要用单数形式。 例如： Walking on the moon is not so easy. 在月球上行
9、走是不容易的。Flying makes me nervous. 飞行使我很紧张。(2) 作宾语，有些动词可以用动名词作宾语。例如：Would you mind turning down your radio a little, please? 你介意把收音机音量调小一点吗？The squirrel was lucky that it just missed being caught. 这松鼠幸运得很，刚逃避了被逮住的厄运。(3) 作表语，动名词作表语，对主语进行说明、解释。例如：Her job is washing, cleaning and taking care of the childr
10、en. 她的工作是洗刷、清扫和照顾孩子。5. She was afraid to tell her parents about it.(1) be afraid表示“害怕做某事”或“不敢做某事”，be afraid 之后可接不定式，也可接名词、代词或of doing sth。例如：She was afraid to tell you. 她害怕告诉你。She is afraid of going out alone late at night. 她很怕深夜独自外出。Im afraid of the dog. 我怕狗。(2) 但若要表示担心可能会发生某事，则只能用 be afraid of doi
11、ng而不能用 be afraid to do。例如：Im afraid of being late for class. 我担心上课迟到。(3) be afraid后可接that从句。例如：He is afraid that his father will be unhappy. 他担心他的爸爸会不高兴。【过手练习】II. 句型转换，每空一词。1. Get up early, or youll be late for school. (改为同义句) _ you _ get up early, youll be late for school.2. Ill go to the city cent
12、re by subway. (改为同义句) Ill _ _ _ to the city center.3. Work hard, and you will catch up with others. (改为同义句)_ you _ hard, you will catch up with others.4.
