試題及答案解析：
36. C句中不定式表示原因: “學(xué)生有機(jī)會(huì)用英語(yǔ)與美國(guó)人交談，很受鼓舞。” 所以應(yīng)用不定式完成式。如果句子用的是一般現(xiàn)在時(shí)are, 那么選A是對(duì)的。
37. Atolerate要求動(dòng)名詞做賓語(yǔ), 只能選A。
38. C動(dòng)名詞being 做students 的邏輯謂語(yǔ), 相當(dāng)于…students… being unable to understand what they read。整個(gè)動(dòng)名詞短語(yǔ)做of的賓語(yǔ)，所以只能選C。
39. D這是一個(gè)含蓄虛擬條件句，前半部分假設(shè)，后半部分真實(shí)，因此應(yīng)選could have caught，意為“我本來(lái)能趕上火車(chē)的，可是那天早上我睡過(guò)頭了”。區(qū)別這類(lèi)含蓄虛擬條件句的關(guān)鍵詞是but。
40. Ddidnt have to do it“不用非得洗(碗)”，符合句意。
