It is all right in theory, but it won’t work in practice.
就理论上来说, 是完全对的, 但是实际上行不通。
2 )so that 引导结果状语从句。
Bring it nearer so that I may see it better. 拿近点我好看清楚。
She worried so that she could hardly eat her supper.
她着急得简直吃不下晚饭了。
3 )辨异: probable, possible, a.
这组词都可用来表示某种可能性。
probable 主要指在有根据、合乎情理的基础上, 看某事是可信的, 有可能得到证实或有发生的可能。possible 表示的可能性要比probable 小些, 往往带有实际希望较小的暗示。试比较:
He is a proba ble choice. 他是个很有希望的人选。
He is a possible choice. 他也是可以考虑的人选。
It is proba ble that he may succeed. 他很可能会成功。
It is possible that he may succeed. 他也许会成功。
8.The difference may be so small that no one is aware of it.
步子不匀的差距很小, 以至于没有人意识到。
1 )“so + 形容词或副词+ that 分句”引导结果状语从句, 表示主句的动作或状态达到何种程度而引起的结果。
He was so angry that he left the room without saying a word.
他非常气愤, 以至于一句话不说就离开了房间。
The book was so boring that he gave up reading it half way through.
这本书很乏味, 他看了一半就放弃不读了。
2 )be aware of sth. 知道某事
I was not awa re of his presence. 我没有觉察到他出席了。
在由从属连接词that 引导的名词从句前, 不用“ of”。在其他名词前通常也不用“of”。
I was not awa re that there was anyone in the room.
我不知道房间里有人。
Are you aware who I am？你知道我是谁吗？
但在以关系代词what 开始的从句前, 必须用“ of”。
He was not awa re of what was going on around him.
他不知道他周围正在发生什么事。
9.But small as it is, it can cause circular movement.
小是小, 但是可以让人转圈走了。
“ small as it is”是由连接副词as 引导的让步状语从句, 而将从句的补语或状语置于句首的一种倒装语序结构。
Poor as he was, he was honest. 他虽然穷却很诚实。
Ta ll as he was, he couldn’t reach the apples.
他虽然高但够不到那苹果树。
10. This explains why the rowers who set out to cross the lake at night rowed in a circle.
这就是桨手们夜晚想划过湖面却在转圈划行的道理。
1 )why 引导的从句在这里是宾语从句。
Please explain why this is impossible. 请说明为什么这不可能。
Could you tell me why you are late？你可否告诉我你为何迟到？
2 )set out 后面跟不定式, 意为“ 开始, 着手；打算”。
Half an hour later I set out to repair my car.
半小时后, 我又开始修车了。
3 )at night 夜里
I usually dream at night. 我夜里经常做梦。
