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

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 the 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，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，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Ⅰ. 仔细阅读对话，选择恰当的答语。1.

句型--Would you mind moving your bike ?

语法要点 学会提出请求

基本用法：1)Would you mind doing?=Do you mind doing..?“你介意…?” “请你…好不好?”是一种比较客气的表达方式。
2)如果要表示“请你不要做…好吗?”只需在doing 前面加not.应答用语：
1)如果同意表示不介意时，可用如下用语来表达：Certainly not.; Of course not.;No,not at all.;Not at all.“好，可以”
2)如果不同意表示介意时，常用“Sorry.”“I’m sorry, but…”及陈述某种理由来表示拒绝或反对。;这一句型中的逻辑主语只能是谈话的对方you，如果想要对方允许自己做某事，可以用 “Would you mind my doing..?句型。

very, too, so, quite以上几个副词均修饰形容词，副词表示程度，“很，太，非常”;very应用最普遍“很”，只是一个表示程度的副词，它表示的程度比quite要强得多，very只用来修饰形容词和副词的原级;too“太”，一般表示“相对某人而言”;so“如此…,那么…”,往往表明某一事物的程度时，会引起另一种后果。换言之，so所修饰的人或物表示原因后面会有表示结果的句子。So…that…如此…以致于;quite既可以表示充分肯定，意思是 “完全;十分”，也可以表示程度，意思是“完全，十分”，也可以表示程度，意思是“相当”，quite可修饰动词，v.ing，形容词，副词，分词等。quite a +adj+n. a very+adj.+n
