You will not succeed ______ you work harder.
A.ifB.whenC.unlessD.because.
C

試題分析:根據(jù)語(yǔ)境可知此句的含義是你不會(huì)成功除非你努力工作。考查的是連詞的基本用法,根據(jù)選擇項(xiàng)的提示可知if引導(dǎo)的是條件狀語(yǔ)從句,when引導(dǎo)的是時(shí)間狀語(yǔ)從句unless引導(dǎo)的是讓步狀語(yǔ)從句because引導(dǎo)的是原因狀語(yǔ)從句。A,B和D都不符合句意,故選C。
點(diǎn)評(píng):unless是從屬連詞,引導(dǎo)條件狀語(yǔ)從句,含有否定意義,相當(dāng)于if條件狀語(yǔ)從句的否定形式。所以u(píng)nless =" if" not。注意:unless引導(dǎo)的條件狀語(yǔ)從句和if條件狀語(yǔ)從句,與其它時(shí)間狀語(yǔ)從句一樣,用一般現(xiàn)在時(shí)代替將來(lái)時(shí)。
