第十期:连词
文法层面上,三点足矣——替换零星词汇、调整语序、加衔接词
替换词汇不是要让文章里有多么的用词多样
而是力主将思路更精确的表达
调整语序仅仅增加一些符合语感的倒装就可以让作文上升一个档次
而以上两个都不如加衔接词来得性价比高
not only… but also 关联两个分句时,一个分句因有否定词not 而必须倒装。
Not only does he like reading stories, but also he can even write some.
但有时and 也可用于否定句。请注意其不同特点:
there is no air or water in the moon.
There is no air and no water on the moon.
not…but… 意思为"不是 ……而是……"
not 和but 后面的用词要遵循一致原则。
They were not the bones of an animal, but (the bones) of a human being.
两个并列连词不能连用,但therefore, then, yet.可以和并列连词连用。
He hurt his leg, and so / and therefore he couldn't play in the game.
worth,worthy,worth-while都为adj. 意为"值得"。
1. worth: be worth + n.
当名词为金钱时,表示"…… 值得……"
be worth doing sth.
"……某事值得被做"
The question is not worth discussing again and again.
2. worthy: be worthy of +n. 当名词为抽象名词时表示"……值得……"
be worthy to be done "某事值得被做"
The question is not worthy to be discussed again and again.
3. worth-while: be worth-while to do sth
"值得做某事"
worth while: It is worth while doing sth
It is worth while sb to do sth.
第十一期:动词和动词语态
系动词:
1)状态系动词
用来表示主语状态,只有be一词,
2)持续系动词
用来表示主语继续或保持一种状况或态度,主要有keep, rest, remain, stay, lie, stand
3)表像系动词
用来表示"看起来像"这一概念,主要有seem, appear, look,
4)感官系动词
感官系动词主要有feel, smell, sound, taste
5)变化系动词
这些系动词表示主语变成什么样,变化系动词主要有become, grow, turn, fall, get, go, come, run.
终止系动词
表示主语已终止动作,主要有prove, trun out, 表达"证实","变成"之意,例如:
The rumor proved false.这谣言证实有假。
do用于倒装句,例如:
Never did I hear of such a thing. 我从未听说过这样的事情。
Only when we begin our college life do we realize the importance of English.
只有在开始大学生活时我们才认识到英语的重要性。
说明: 引导此类倒装句的副词有never, seldom, rarely, little, only, so, well等。

let 的用法
1)当let后只有一个单音节动词,变被动语态时,可用不带to 的不定式。

第十三期:独立主格和特殊词
独立主格结构的特点:
1)独立主格结构的逻辑主语与句子的主语不同,它独立存在。
2)名词或代词与后面的分词,形容词,副词,不定
式,介词等是主谓关系。
3)独立主格结构一般有逗号与主句分开。
举例:
The test finished, we began our holiday.
= When the test was finished, we began our holiday.
考试结束了,我们开始放假。
The president assassinated, the whole country was in deep sorrow.
= After the president was assassinated, the whole country was in deep sorrow.
总统被谋杀了,举国上下沉浸在悲哀之中。
Weather permitting, we are going to visit you tomorrow.
如果天气允许,我们明天去看你。
独立主格结构使用介词的问题:
当介词是in 时,其前后的两个名词均不加任何成分(如物主代词或冠词),也不用复数。但 with 的复合结构不受此限制
A robber burst into the room, knife in hand.
( hand前不能加his)。
当表人体部位的词做逻辑主语时,及物动词用现在分
词,不及物动词用过去分词。
He lay there, his teeth set, his hand clenched, his eyes looking straight up.
cease to do 长时间,甚至永远停做某事。
cease doing 短时停止做某事,以后还会接着做。
be afraid to do不敢,胆怯去做某事,是主观上的原因不去做,意为"怕";
be afraid of doing担心出现doing的状况、结果。 doing 是客观上造成的,意为"生怕,恐怕"。
interested to do 对做某事感兴趣,想了解某事。
interested in doing 对某种想法感兴趣,doing 通常为想法
mean to do 打算、想
mean doing意味着
在attempt, intend, begin, start 后接 know, understand, realize这类动词时,常用不定式to do。
感官动词 see, watch, observe, notice, look at, hear, listen to, smell, taste, feel + do 表示动作的完整性,真实性; +doing 表示动作的连续性,进行性 |
