A．Whether B．What C．That D．How 答案　B 解析　句意為：一些人眼中的缺點(diǎn)是別人眼中的優(yōu)點(diǎn)。分析句子可知，________ some people regard as a drawback為主語(yǔ)從句，且從句中缺賓語(yǔ)，只能用what來(lái)引導(dǎo)；that引導(dǎo)主語(yǔ)從句不作成分。 (2)One reason for her preference for city life is ________ she can have easy access to places like shops and restaurants. A．that B．how C．what D．why 答案　A 解析　系動(dòng)詞is之后是一個(gè)表語(yǔ)從句，而從句的結(jié)構(gòu)完整，不缺少任何成分，所以用that引導(dǎo)。 方法2　語(yǔ)序判斷法 一般來(lái)說(shuō)，名詞性從句中(當(dāng)然不只是名詞性從句，其他從句也是如此)，從句的語(yǔ)序要用陳述語(yǔ)序，這樣也就很容易作答了。 When changing lanes，a driver should use his turning signal to let other drivers know ________. A．he is entering which lane B．which lane he is entering C．is he entering which lane D．which lane is he entering 答案　B 解析　which引導(dǎo)的句子作know的賓語(yǔ)，句子用陳述語(yǔ)序。故B項(xiàng)為正確答案。 方法3　句子成分分析法 看從句缺不缺成分，不缺就用that，whether或if；缺成分就用wh類連接詞(包括how，because等)。 (1)We haven’t discussed yet ________ we are going to place our new furniture. A．that B．which C．what D．where 答案　D 解析　句意為：我們還沒(méi)有討論把我們的新家具放在哪里。分析句子可知，此題考查賓語(yǔ)從句。賓語(yǔ)從句中缺少地點(diǎn)狀語(yǔ)，因此選擇D。 (2)As a new graduate，he doesn’t know ________ it takes to start a business here.
