)用whether或if。whether更常用。故選B。10.考查讓步狀語(yǔ)從句。句意為“無(wú)論他多么努力，似乎永遠(yuǎn)無(wú)法讓老板滿意”。強(qiáng)調(diào)努力的程度，應(yīng)用However+adj./adv.結(jié)構(gòu)。故選B。11.考查定語(yǔ)從句。thebook是先行詞，指物，關(guān)系代詞在從句中作賓語(yǔ)，應(yīng)用which或that。whom指人，that在非限制性定語(yǔ)從句中可指物。故選B。12.考查主語(yǔ)從句。Itisessentialthat后接主語(yǔ)從句，從句應(yīng)用動(dòng)詞原形。故選A。13.考查代詞辨析。few修飾可數(shù)名詞復(fù)數(shù)，afew表示一些；little修飾不可數(shù)名詞，alittle表示一些。此處指知道的事情很少，應(yīng)用little。故選A。14.考查名詞性從句。Thereason后接表語(yǔ)從句，解釋原因，應(yīng)用that引導(dǎo)。why引導(dǎo)定語(yǔ)從句，修飾reason。故選D。15.考查定語(yǔ)從句。someone指人，作先行詞，關(guān)系代詞在從句中作主語(yǔ)，應(yīng)用who或that。whom作賓語(yǔ)，which指物。故選A。16.考查固定搭配。Accordingtoresearch為固定搭配，意為“根據(jù)研究表明”。故選According。17.考查副詞。Thus意為“因此，從而”，引導(dǎo)結(jié)果狀語(yǔ)，對(duì)應(yīng)句意“因此，那些長(zhǎng)期睡眠不足的人往往難以集中注意力”。故選Thus。18.考查連詞。Because引導(dǎo)原因狀語(yǔ)從句，對(duì)應(yīng)句意“因?yàn)樗卟蛔愕娜烁菀捉?jīng)歷負(fù)面情緒”。故選Because。19.考查介詞。Withoutadequaterest為介詞短語(yǔ)，意為“沒(méi)有充足的休息”，引導(dǎo)條件狀語(yǔ)，對(duì)應(yīng)句意“沒(méi)有充足的休息，大腦就無(wú)法更好地調(diào)節(jié)壓力荷爾蒙”。故選Without。20.考查連詞。so...that...結(jié)構(gòu)，so引導(dǎo)結(jié)果狀語(yǔ)，that引導(dǎo)結(jié)果從句，意為“如此……以至于……”，連接前后兩個(gè)分句，表達(dá)因果關(guān)系。故選so。21.考查虛擬語(yǔ)氣。Itisimportant/necessary/essentialthat...結(jié)構(gòu)，主語(yǔ)從句應(yīng)用動(dòng)詞原形。原句should已包含在important中，應(yīng)刪除。故選ImportantthatyoufinishtheprojectbeforeFriday。22.考查同義轉(zhuǎn)述。Thereason
