高三英語重點(diǎn)知識(shí)點(diǎn)歸納
1. 對(duì)在句中作時(shí)間、條件、原因還是別的狀語不是很清楚。
2.分不清何時(shí)用現(xiàn)在分詞、何時(shí)用過去分詞。
解決辦法：
1.理解分詞作狀語時(shí)可以轉(zhuǎn)換成相應(yīng)的.狀語從句。
2.分清何時(shí)用現(xiàn)在分詞、何時(shí)用過去分詞。
用法講解：
1. 分詞或分詞短語作狀語時(shí)，可以表示時(shí)間、原因、讓步、條件，方式或伴隨狀況。通?？赊D(zhuǎn)換成相應(yīng)的狀語從句;表示方式或伴隨狀況時(shí)可以轉(zhuǎn)換成并列句或非限制性定語從句。例如：
Put into use in April 2000 (=When it was put into use in April 2000), the hotline was meant for residents reporting water and heating supply breakdowns. 分詞短語作時(shí)間狀語
Blamed for the breakdown of the school computer network (=Because she was blamed for the breakdown of the school computer network), Alice was in low spirits. 分詞短語作原因狀語
Given time (=If he is given time), he’ll make a fist-class tennis player. 分詞短語作條件狀語
We often provide our children with toys, footballs or basketballs, thinking that all children like these things. (= and think that all children like these things.) 分詞短語作伴隨狀語
2. 有時(shí)為了強(qiáng)調(diào)，分詞前可帶when, while, if, though, as if, unless等連詞一起作狀語，以便使句子的意思更清楚、更連貫。例如：
When comparing different cultures, we often pay attention only to the differences without noticing the many similarities.
Though tired, he still continued reading.
3. 現(xiàn)在分詞和過去分詞作狀語時(shí)的用法比較。
不管是現(xiàn)在分詞還是過去分詞單獨(dú)作狀語，其邏輯主語必須與主句的主語一致。分詞作狀語通?？赊D(zhuǎn)換成一個(gè)相應(yīng)的狀語從句或并列句，如果狀語分句或并列句中的謂語動(dòng)詞為被動(dòng)結(jié)構(gòu)，就用過去分詞;如果狀語分句或并列句中的謂語動(dòng)詞為主動(dòng)結(jié)構(gòu)，就用現(xiàn)在分詞。例如：
When compared with the size of the whole earth , the biggest ocean does not seem big at all.
分詞部分相當(dāng)于When the biggest ocean is compared with the size of the whole earth, 主語與分詞是被動(dòng)關(guān)系，所以用過去分詞。
When comparing it with the size of the whole earth, we find that the biggest ocean does not seem big at all.
When we compare it with the size of the whole earth... 主語與分詞是主動(dòng)關(guān)系, 所以用現(xiàn)在分詞。
Faced with a bill for,000(=Because he is faced with a bill for,000), John has taken an extra job.
Whenever hewas asked why he was late for class, he would answer carelessly, always saying the same thing (= and he would say the same thing).
注意：
1. 現(xiàn)在分詞有兩種時(shí)態(tài)：一般式doing和完成式having done。一般式通常表示與主句的謂語動(dòng)詞所表示的動(dòng)作同時(shí)發(fā)生或無先后;完成式則強(qiáng)調(diào)分詞所表示的動(dòng)作先于謂語動(dòng)詞所表示的動(dòng)作。如：
While walking in the street, we met some friends of ours.(同時(shí)發(fā)生)
Having waited in the queue for half an hour, Tom suddenly realized that he had left his wallet at home. (“等待”先于謂語動(dòng)詞“意識(shí)到”)
2. 分詞的否定式的構(gòu)成: not +分詞。 Not having received a reply, he decided to write again.

不定代詞的用法

1.用作主語

look at a book?
1. 表示閱讀性地“看書”(即讀書)，一般要用動(dòng)詞 read。如：
Don’t read such books. 不要讀那樣的書。
He is reading a book on Shakespeare. 他在看一本關(guān)于莎士比亞的書。
但是，在許多情況下，“看書”只需用read 就夠了(尤其是泛泛地表示“看書”時(shí))，無需后接book作賓語。如：
In the evening I usually read. 晚上我常常看書。
This light is too poor to read by. 這光線太暗不能看書。
I read much less now than I did at school. 我現(xiàn)在看書遠(yuǎn)比我上學(xué)時(shí)少。
2. 若不是表示閱讀性地“看書”，而只是大概地看一看，比如看看書的封面、定價(jià)、內(nèi)容提要等，或者回答問題時(shí)看看書的某些章節(jié)或字句等，或者是考試時(shí)悼詞楸鏡齲此時(shí)都不宜用動(dòng)詞read, 可用look at, see 等。如：
Can I look at those books? 我可以看看那些書嗎?
Jim demanded to see my books. 吉姆要求看看我的書。
Please answer my questions without looking at your books. 請(qǐng)不看書回答我的問題。
