仁爱版八年级下英语教材梳理复习课件

及时巩固 1.用loud,loudly,aloud填空 (1)He heard a cock crow loudly . (2)He has a loud voice. (3)The boy is crying aloud .
2.alone/lonely 1)alone可以作形容词,也可以作副词,表示“单独,独自”,不表示心理上的 “孤独”,常作表语或状语,不能作定语。如: He isn't alone because he lives with his family. 他不是单独无伴的,因为他和家人住在一起。 2)lonely是形容词,常作定语或表语。作表语时,强调人的主观感受,表示心理 上的“孤独,寂寞”;作定语时,意为“偏僻的,人迹罕至的”,常用来修饰表示 地点的名词。如: Mary feels lonely in the new city. 玛丽在这个新城市里感到寂寞。
注意 loudly比用作副词的loud使用范围更广,它除与speak、talk、laugh等 动词连用外,还可与其他表示声响的动词连用,且可以放在这些动词之前或 之后。如: The man snored loudly.这个人鼾声打得响。 另外,在用于比较级或最高级时,通常用 loud,而不用 loudly。如: Who laughed loudest?谁笑的声音最大?
2)neither(两者)都不,neither...nor...既不……也不……。如: Neither you nor he has made the mistake. 犯错误的既不是你也不是他。
4.He refused to play soccer or go to the movies with his friends.他拒绝和他的朋 友们去踢足球或者看电影。(P16) 基本用法 refuse v.拒绝,回绝。后面常接名词、代词或动词不定式作宾 语。如: The patient has the right to refuse treatment.病人有权利拒绝接受治疗。 I refuse to answer that question. 我拒绝回答那个问题。 拓展 refuse用作名词时意思是“废弃物,垃圾”,是不可数名词。如: The water was full of flotsam and refuse. 水里满是废弃物和垃圾。

宾语从句
在初中阶段，宾语从句是重要的语法点，与宾语从句有 关的考点有很多，常见的有，
考点1：宾语从句的引导词 宾语从句的引导词有三类，分别是
that
表陈述语气，通常可以省略。
if/whether
表疑问语气，意为“是否”。
特殊疑问词
常见的特殊疑问词有when, where, how, what, why等。
考点3：宾语从句在时态上应遵循时态呼应原则 在宾语从句中，谓语动词时态要受到主句谓语动词时态的制 约，一般要遵循以下三条原则： 1．如果主句是祈使句或主句中的谓语动词是一般现在时或 一般将来时，则宾语从句可根据实际需要选用时态。如： Mary says she will come back soon. Will you tell us which places you visited during the vacation?
考点4：宾语从句的“否定转移” 当主句的谓语动词为think, believe等词，且主语为第一 人称时，从句中的否定词not应转移到主句谓语动词。如： I think. She can't come.(合并为一句) →I don't think she can come.
考点5：宾语从句的简化结构 由特殊疑问词引导的宾语从句通常可以简化成“特殊疑问词 ＋不定式”结构，此时主从复合句也就变成了简单句，但简化 必须符合以下两种条件： 1．简单句的疑问词为原宾语从句的引导词； 2．原从句的主语应与主句的主语或间接宾语一致。 I don't know what I should do next.(改为简单句) →I don't know __w__h_a_t_to__d_o_n__ex_t______.
