2021年初中英語輔導(dǎo)：主語從句的概念與類型

　　中考網(wǎng)整理了關(guān)于2021年初中英語輔導(dǎo)：主語從句的概念與類型，希望對同學(xué)們有所幫助，僅供參考。

　　主語從句在復(fù)合句中作主句的主語,引導(dǎo)主語從句的詞有從屬連詞that, whether以及連接代詞who, what, which, whoever, whatever, whichever和連接副詞when, where, why, how等. 例如:

　　That she was chosen made us very happy.

　　她當(dāng)選了使我們很高興.

　　What caused the accident is a complete mystery.

　　是什么導(dǎo)致了這次事故還完全是一個(gè)謎.

　　Whether she will come or not is still a question.

　　她是否來還是一個(gè)問題.

　　Which team will win the match is still unknown.

　　哪個(gè)隊(duì)會贏得這場比賽還不知道.

　　Whoever comes to the party will receive a present.

　　參加聚會的每一個(gè)人都將收到一份禮物.

　　When they will start has not been decided yet.

　　他們何時(shí)出發(fā)還沒決定.

　　注意:上述例句中的主語從句都是放在句首,但有時(shí)為了使句子結(jié)構(gòu)平衡,避免"頭重腳輕",常用it作形式主語,而把從句放在后面. 例如:

　　It is a pity that she has made such a mistake.

　　她犯了這樣一個(gè)錯(cuò)誤,真是遺憾.

　　It depends on the climate whether they are going shopping today.

　　他們是否今天去購物還得看天氣情況.

　　這樣就構(gòu)成了下面一些常用句型:

　　1)It is + adj. / n. +從句

　　It is a pity/shame that...遺憾的是……

　　It is possible that...很可能……

　　It is unlikely that...不可能……

　　2)It +不及物動詞+從句

　　It seems/appears that...似乎……

　　It happened that...碰巧……

　　3)It + be +過去分詞+從句

　　It is said that...據(jù)說……

　　It is known to all that...眾所周知……

　　It is reported that...據(jù)報(bào)道……

　　It is believed that...據(jù)信……;人們相信……

　　It is suggested that...有人建議……

　　It must be pointed out that...必須指出……

　　It has been proved that...已證明…….例如:

　　It is believed that at least a score of buildings were damaged or destroyed.據(jù)信,至少有二十座樓房遭到破壞或徹底毀掉.

　　It is suggested that the meeting should be put off.有人建議會議延期召開.

　　It s reported that three people were killed in the accident and five were hurt badly.據(jù)報(bào)道,事故中三人喪生,五人重傷.

　　It is known to all that Taiwan is an inseparable part of China.眾所周知,臺灣是中國不可分割的一部分.
