答案解析

1. C句中不定式表示原因: “學生有機會用英語與美國人交談，很受鼓舞。” 所以應用不定式完成式。如果句子用的是一般現在時are, 那么選A是對的。

2. Atolerate要求動名詞做賓語, 只能選A。

3. C動名詞being 做students 的邏輯謂語, 相當于…students… being unable to understand what they read。整個動名詞短語做of的賓語，所以只能選C。

4. D這是一個含蓄虛擬條件句，前半部分假設，后半部分真實，因此應選could have caught，意為“我本來能趕上火車的，可是那天早上我睡過頭了”。區別這類含蓄虛擬條件句的關鍵詞是but。

5. Ddidnt have to do it“不用非得洗(碗)”，符合句意。
