句型透视 必背句 ‎1.But my mother wants me to drink it.‎ ‎2.She says it’s good for my health ‎ ‎3.Forty-five percent exercise four to six times a week.‎ ‎4.She has a lot of good habits.‎ 例句解析 ‎1.But my mother wants me to drink it.‎ 但是我的妈妈想让我喝它。Want=would like,其后可接名词，动词不定式等。‎ （1） want to do sth.想要做某事。Eg:I want to buy some apples.‎ （2） want sth. 想要某物。Eg:He wants a good job.‎ （3） want sb. to do sth.想要某人做某事。Eg:His wife wants him to buy a car.‎ ‎ 2.She says it’s good for my health ‎ 她说对我的健康有益。（1）be good for“对……有益”，反义词组是be bad for“对……有害”。‎ ‎（2）be good to“对……友好”，相当于be friendly to/ be kind to,后面一般跟表示人或者人格化的名词。Eg: She is kind/ friendly to us.‎ ‎(3) be good at“擅长，善于”，后面接名词，代词，或动名词。相当于do well in。‎ ‎3.Here are the results.这是结果。‎ Here are…表示“这儿……有，这儿是……”。此句是一个倒装句，here在这儿做表语。其中here后be的单复数形式要根据be后面名词的单复数来确定。Eg: Here is a letter for you.‎ Eg: Here are some flowers for us.‎ ‎4. W e found that only fifteen percent of our students exercise every day.我们发现我们的学生仅仅百分之十五每天锻炼。此句是一个宾语从句。W e found是主句，only fifteen percent of our students exercise every day是宾语从句。percent百分之……与不可数名词和单数名词连用时，动词一般用单数。与复数名词连用时，动词一般用复数。‎ every day是副词短语，作状语，“每一天”，=each day。‎ Everyday是形容词，只做宾语，“日常的”，相当于daily。‎ ‎5.It is good to relax by using the Internet or watching game shows.通过使用网络或者观看游戏节目来放松是好的。此句型为It’s+adj.+(for sb)+to do sth.‎ 在这个结构中，It是形式主语，真正的主语是to do sth by为介词，意为“用……方法”、“以……方式”，后接名词或动名词作方式状语。by还常与交通工具的名词连用构成介词短语。by还可与时间连用，意为“在……之前”、“到……为止”。‎ eg：by making flashcards，by bus，by ten o’clock
