1、B.后面用動(dòng)詞原形則need是情態(tài)動(dòng)詞.如：Need you wash the clothes?
后面用名詞或者動(dòng)詞不定式時(shí),作實(shí)意動(dòng)詞.如：I need you./You need to do something to improve yourself?
2、A.這應(yīng)該是個(gè)虛擬句.虛擬語氣中時(shí)態(tài)都要用過去,would用在此表過去將來時(shí).
3、B.be faced with= face,在這里和encounter同義.2.suppose的虛擬不是要用should嗎？3.答案選A2、這是一種虛擬，另一種虛擬是用過去時(shí)態(tài)。如：If I were you, I wouldn't have broken my promise. 如果我是你，我就不會(huì)背棄承諾。3、就是選A，解析是對(duì)的，B少了一個(gè)be。
