所以 that 从句前有一个受 such 修饰的名词；而 so 是副词，用以修饰形容词或副词， 因此 that 从句前一般不出现名词。如 They are such kind-hearted teachers that people in the village all respect them. The exam was so difficult that many students failed to pass it. a) 如果名词是可数名词的单数形式，such 和 so 的位置不同：
她那样的嗓子。 � Such 常和表示结果的 that 从句搭配，表示“如此….以至于…”如 It was such a hot day that we all had to stay at home.
2
�
Such…that…和 so…that…都可用来引出一个结果状语从句。 由于 such 是形容词，
其它”结构。 h) 表示“越….越….”, 可使用“the+形容词或副词的比较级，the+形容词或副词
的比较级”结构。 2 .一般将来时
a)
一般将来时的构成： 由助动词 shall 或 will 加动词原形构成， shall 用于第一人称。
在口语中，will 在名词或代词后常简略为’ll， will not 常简略为 won’t。这个时态的 肯定，否定和疑问结构可表示如下：
的动作。这一特定的过去时间，除有上，下文暗示以外，一般用时间状语来表示 2． not …until 直到…才。表示动作在某时之前尚未开始，直到此时动作才开始。 not…until 可以用 after 或 when 来代替，但主句谓语动词要用肯定形式。Until 为连词 时后接时间状语从句，until 作介词时，后面接表示时间的名词。Until 用于肯定句多 表示动作或状态一直延续到 until 所表示的时间为止，意思为“直到…” from..till…中 till 往往表示不太具体的时间。From …to…或 from…until 常用来表示具体的时间。 3． find it…to do，it 在此句中为形式宾语代表动词不定式，动词不定式为真正的宾 语，常用于这种用法的动词有 find, feel, think, make 等。 4． “疑问词+不定式“结构相当于一个名词性从句，常常可用同等成分的从句代替。 改写时，只需在疑问词后面加一个适当的主语（这个主语一般与主句的主语一致） ， 并将不定式改成适当形式的谓语即可。如，Where to go is still a question.= Where we should go is still a question. 5． when 与 while:when 连接的状语从句是个特殊句型，“前一个分句（谓语动词用 过去进行时）+when(作并列连词，意思为“这时，突然”)+后一个分句（谓语动词用一 般过去时）”表示在前一个动作正在进行的过程中突然发生了后一个动作， when 强

五. 动词不定式（to do）的用法1. 作主语为避免句子的头重脚轻，常用it作为形式主语，而真正的主语动词不定式后置。
常用句型：It +be+adj./n.+(for/of sb.) to do sth./It takes sb. some time to do sth.2. 作宾语动词want, decide, hope, ask, agree, choose, learn, plan, need, teach, prepare常接动词不定式作宾语。
3. 作（后置）定语常用于“have/has＋sth.＋to do”或“It‟s time to do sth.”等结构中。
4. 作宾语补足语tell, ask, want, invite, teach, like, call等可接带to的动词不定式作宾语补足语，构成tell/ask/want /call/invite sb. to do sth.结构。
【注意】动词不定式作使役动词和感官动词的宾语补足语时应省去to：“一感(feel)，二听(listen to, hear)，三让(let, make, have，四看(look at, see, watch, notice)，半帮助(help)”。
5. 动词不定式作状语主要用来修饰动词，表示目的，结果或原因。
为了强调目的，有时可以把动词不定式放在句首，或在不定式前加in order (to) 或so as (to) “为了，目的是”。
六. Could you please...？句型1. 请求别人时通常用此句型，也可以说Can you...please?情态动词could或can在这里均表示请求，在意思上无区别，但是用could在于其显得更委婉、客气、诚恳。
在日常生活中常使用could you/I...?若在句末加上please，则显得更礼貌。
