单元语法精讲与精练
语法精讲 一、宾语从句(Ⅰ) 在复合句中，由一个句子充当宾语，这个句子叫作宾语从句。宾语从句需要 注意以下三点： 1．引导词 宾语从句的引导词，可用下面的歌诀记忆： 陈述 that 来引导，有时可以省略掉。 一般问句表“是否”，if 或 whether 作引导。 特殊疑问作宾从，疑问词连接就可行。
(3)如果宾语从句讲述的是客观事实、普遍真理、自然现象、名言、警句、 格言、谚语时，不管主句是什么时态，宾语从句都要用一般现在时。如： She said that light travels faster than sound. 她说光比声音传播得快。
二、感叹句 感叹句是用来表示人的喜、怒、哀、乐等强烈感情的句子，句末通常用感叹 号，也可用句号。感叹句通常由 what 或 how 引导。 1．what 引导的感叹句，主要有以下几种： (1)What(＋a/an)＋形容词＋可数名词单数＋主语＋谓语！如： What a beautiful school it is！这个学校太漂亮啦！ (2)What＋形容词＋可数名词复数＋主语＋谓语！如： What hard－working students they are! 学生们多么用功呀！ (3)What＋形容词＋不可数名词＋主语＋谓语！如： What fine weather it is！多好的天气呀！
二、用 that，what，how，if 或 whether 填空。 1．Li Hong told _t_h_a_t__ she was cooking at 7：00 yesterday morning. 2．I wonder ___if_/_w_h_e_t_h_e_r___ I can get some advice from you. 3．I don't know ___w_h_e_t_h_e_r___ or not they will come for our help. 4．__H__o_w__ useful the iphone 8 is！But I can't afford it. 5．_W__h_a_t_ a wonderful talent show they performed in their school yesterday! 6．_W__h_a_t__ nice children Lily and Lucy are！They help Mrs.Li clean the house every day. 7．Our geography teacher said __t_h_a_t_ the earth goes around the sun. 8．__W__h_a_t_ good advice they gave us!

4.名词复数的构成规则 (1)大多数名词的复数形式由“单数名词加s”构成。 如： pen—pens, orange—oranges (2)有些名词以s,x,ch或sh结尾,则在词尾加es构 成复数。如： watch—watches, bus—buses, box—boxes (3)以辅音字母加 y结尾的名词,变 y为i,再加es。如： family—families, dictionary—dictionaries
Unit 2 This is my sister.
语法专பைடு நூலகம்2 指示代词
1.This is my sister. 2.That’s my family. 3.These are my brothers. 4.Those are my parents.

三、用所给词的适当形式填空 This 11．_____(this) isn’t my pen.
12． _____(that) are my friends. Those that 13．Is _____(that) man your father? 14． _____(this) are her classmates, Tom and Ann. These
