(1)rather than經(jīng)常用在“平行結(jié)構(gòu)”里:即與兩個(gè)形容詞、兩個(gè)狀語(yǔ)詞組、兩個(gè)名詞或代詞、兩個(gè)動(dòng)詞不定式、或兩個(gè)v.ing形式連用。
(2)rather than后的動(dòng)詞要和主句中與之相當(dāng)?shù)膭?dòng)詞在形式上一致。
(3)rather than位于句首時(shí)，其后的動(dòng)詞必須用v.-ing形式。
練：nuclear science should be developed to benefit the people _______harm them.
a.more than b.rather than c.other than d.better than
提示:rather than 意為“而不是”，句意為:發(fā)展核科學(xué)應(yīng)該使人們受益，而不是對(duì)他們有害。故選b。
答案:b
句型
1.do everything one can to do
講：注意觀察下面兩個(gè)教材原句:
we will not let our history and culture be destroyed and we will do everything we can to save our city.
我們不會(huì)讓我們的歷史和文化被毀滅的，我們將盡我們的所能去挽救我們的城市。
they do their best to win medals.
他們努力去獲得獎(jiǎng)牌。
“盡其所能去做某事；盡力做某事”可用 sb.do what one can to do或sb.do everything/all(that) one can to do來(lái)表達(dá)。該句型中can 后省略了do，不定式作目的狀語(yǔ)。也可用do/try one’s best to do來(lái)表達(dá)。
例：whenever he met with difficulty,she would do what she could to help him.
=whenever he met with difficulty,she would do all/everything she could to help him.
=whenever he met with difficulty,she would do/try her best to help him.
每當(dāng)他遇到困難時(shí)，她總是盡她所能去幫助他。
練：these wild flowers are so special i would do ______i_______ them.
a.what；can save b.all what；can to save
c.what；can to save d.everything；can save
提示:在sb.do what one can to do結(jié)構(gòu)中what one can是賓語(yǔ)從句，what后不可再使用關(guān)系代詞；在sb.do everything/all(that)one can to do中，that one can是定語(yǔ)從句，該從句中只能使用關(guān)系代詞that，everything/all that等于what；在以上結(jié)構(gòu)中can后省略了動(dòng)詞do，動(dòng)詞不定式作目的狀語(yǔ)。故選c。
答案:c
2.would rather...(than...)
講：注意觀察下面教材原句:
i’d rather watch it than play it.我寧愿看球而不愿意打球。
would rather通常縮寫(xiě)為 ’d rather。
(1)would/had rather...（than）意為“寧愿……而不愿；寧愿；更喜歡”。
(2)would rather后接從句時(shí)，從句中用過(guò)去時(shí)（表現(xiàn)在或?qū)?lái)的虛擬）或過(guò)去完成時(shí)（過(guò)去的虛擬）。
例：—do you want to come with us?你想跟我一起來(lái)嗎？
