1、最新初二八年级下册英语第五单元知识点优秀名师资料初二(八年级)下册英语第五单元知识点初二(八年级)下册英语第五单元知识点 初二(八年级)下册英语第五单元知识点主要是依据初二(八年级)下册英语教材，从引导条件状语从句等重要的知识点、基础训练总结了初二(八年级)下册英语第五单元知识点，适合初二学生学习英语、中考考生备考英语。 知识点: 1.If引导的条件状语从句:1)构成:if引导的条件状语从句表示“如果”。构成形式为“主句+一般将来时时态+if从句+一般现在时态”，或“If从句+一般现在时态，主句+一般将来时态”。2)用法:表示假设或条件 2.half 与half of的用法:1)half th

2、e class中的“half”为形容词，意思“一半的，半个的”2) “half of+代词/the+名词”中的half为名词，意思为“一半，半个”。当该结构在句子作主语时，谓语动词必须和该词组中的代词或名词保持数的一致。即当代词或名词为单数时，谓语动词用第三人称单数形式;若所接名词或代词为复数，则谓语动词用复数形式。 3. all the time与always: all the time是个副词性的短语，意思为“一直”“始终”，表示某一特定阶段开始一直到结束，不表示频度，多置于句末。除此，all the time还有“不断”的意思;always为表示频度的副词，意思为“总是”，表示动作的反复

3、，状态的继续，中间没有间断，其反义词为never。它与进行时态连用时，常翻译成“总是”，“老是”，带有赞美，厌烦，不满等感情色彩。 4.Enough的用法:1)enough to do sth表示“足够可以做”2)enough也可以用“for+宾语+to do sth的结构”3)enough修饰名词时前面不用冠词4)当主语是代词时，enough可以作表语。当主语是名词时，enough不能做表语。 5.Choose的用法:1)choose+名词 意思为“选择”;2)choose+between/from从中选择;3)choose to do选择做某事 6.Exercise的用法:1)运动，锻炼，

4、是不可数名词2)体操，练习，是可数名词。3)动词，使.运动 7.wear, put on, have on, dress: wear“穿着”“戴着”，表示状态，是延续性动词，一般现在时表示经常状态，现在进行时表示暂时状态;put on“穿上”“戴上”，表示动作，是非延续性动词;have on“穿着”“戴着”，表示状态可以与wear互换;dress“穿上”“穿着”，既表示状态，也表示动作，既可以作及物动词，也可以作不及物动词。Dress作及物动词，表示“给自己或别人穿(衣服)”，宾语是人，常用被动语态。dress oneself给。穿衣服。dress up化装 8.a lot, a lot of

5、与lots of三者都有“许多，很多”的意思。a lot of, lots of一般用于肯定句，后接可数名词复数或不可数名词;a lot作名词时=a lot of thins,作副词，修饰动词或形容词，副词比较级。 基础达标 ?. 仔细阅读对话，选择恰当的答语。 1. If I see him again, I _ (tell) him what you said. 2.
