非謂語(yǔ)動(dòng)詞與獨(dú)立主格:短語(yǔ),句子(或者句子,短語(yǔ))
當(dāng)短語(yǔ)部分有獨(dú)立主語(yǔ),并且該主語(yǔ)不同于句子主語(yǔ),這時(shí)短語(yǔ)結(jié)構(gòu)稱為獨(dú)立主格。(它最明顯的特點(diǎn)是短語(yǔ)部分有獨(dú)立的主語(yǔ))。
獨(dú)立主格的結(jié)構(gòu)1:名詞(代詞) 分詞 [現(xiàn)在分詞、過去分詞]
現(xiàn)在分詞表示主動(dòng)的,正在進(jìn)行的行為;過去分詞表示被動(dòng)的,已經(jīng)完成的行為。 作題時(shí)要通過判斷動(dòng)作與名詞(代詞)之間的關(guān)系來(lái)確定是使用現(xiàn)在分詞還是過去分詞。當(dāng)動(dòng)作由名詞(代詞)發(fā)出時(shí)使用現(xiàn)在分詞,而名詞(代詞)是受動(dòng)者時(shí)則用過去分詞。
1. Silver is the best conductor of electricity, copper _B_ it closely.
A followed B following C to follow D being followed
2. All things _A_, the planned trip will have to be called off.
A considered B be considered C considering D having considered
call off 取消; cancel vt. 取消; 四級(jí)中的考點(diǎn)就是現(xiàn)在分詞和過去分詞的區(qū)別。
獨(dú)立主格的結(jié)構(gòu)2:with 名詞(代詞) 分詞 [句子當(dāng)中作狀語(yǔ)]
3. After the Arab states won independence, great emphasis was laid on expanding education, with girls as well as boys _C_ to go to school.
A to be encouraged B been encouraged C being encouraged D be encouraged
as well as 和(相當(dāng)于and); be encouraged不會(huì)考。
動(dòng)詞不定式有預(yù)示將來(lái)行為的含義。to be encouraged 將要被鼓勵(lì);
been encouraged 已經(jīng)被鼓勵(lì)完了,與主句的謂語(yǔ)動(dòng)詞相對(duì);being encouraged 正在被鼓勵(lì)
短語(yǔ)部分沒有獨(dú)立主語(yǔ),則短語(yǔ)結(jié)構(gòu)稱為非謂語(yǔ)動(dòng)詞。
非謂語(yǔ)動(dòng)詞的結(jié)構(gòu):分詞(分詞短語(yǔ))
句子的主語(yǔ)決定非謂語(yǔ)動(dòng)詞中的分詞是用主動(dòng)還是被動(dòng)形式。如果是句子的主語(yǔ)發(fā)出動(dòng)作,則使用現(xiàn)在分詞;如果動(dòng)作不是由句子的主語(yǔ)發(fā)出,則使用過去分詞。
1.No matter how frequently _A_, the works of Beethoven always attract large audiences.
A performed B performing C to be performed D being performed
perform vt. 表演,演出,演奏;
to be performed 將要被演奏; being performed 正在被演奏;
一些特殊的動(dòng)詞:
第一點(diǎn):forget 忘記; [反義] remember 記得;
這兩個(gè)詞后加動(dòng)詞不定式表示將要進(jìn)行的行為;這兩個(gè)詞后加動(dòng)詞ing形式表示已經(jīng)做過的事情。
注意:動(dòng)名詞與現(xiàn)在分詞形式一樣,但含義不同。這兩個(gè)詞后加動(dòng)詞ing形式都是動(dòng)名詞。
forget to do sth. 忘記要去做某事; forget doing sth. 忘記做過某事;
remember to do sth. 記得要去做某事; remember doing sth. 記得做過某事;
2. I remember _B_ to help us if we ever got into trouble.
A once offering B him once offering C him to offer D to offer him
offer vt. 提出,提供; offer sb. sth. / offer to do sth.
him once offering 如果改成 his once offering 也正確。
