41、不好意思让您久等了.A选项正确.其中B选项是算了吧的意思,CD两项明显意思错误.
42、我错过了昨天的足球决赛.先排除AD两项,一个意思是好主意,D项意思是我听到这个消息非常高兴.C项意思是下次不要忘了.所以选B,真遗憾.
43、你要茶还是咖啡?首先排除A,句子里没有出现牛奶.B的意思是我喜欢茶.这句话如果是I“d like tea,please,就对了.D项none是形容三种或三种以上的东西的.
44、让我们去西湖野餐吧.A项是不介意的意思,B项是没关系,C项是好主意,D项是你真幸运.可想而知,这里提议去野餐,我们选择好主意!
45、你父亲多久会飞来纽约?how soon 提问,一般都是问多久之后,没有很精确的时间点,也不是过去时态,而是将来时态,所以排除AB,D项是一年两次的意思,表示频率,当用how often提问时,才会这么形容.
46、假期愉快!这是一个固定的搭配,当别人祝你开心,愉快时,你需要说同乐,正确的是D项的表达.
47、让我自我介绍一下,我叫 steward．别人介绍自己之后,你当然要说nice、
Pleased to meet you.而不是好荣幸!我不知道!.
48、你介意把窗户关了么?外面在刮风.英语中,这是如果你说yes,就是介意,no就是不介意.最佳选项是not at all.
49、很好的派对,难道不是吗?这是你只需要回答是的,而不是我的朋友很棒,我们以前见过吗?很高兴再次见到你.
50、对不起,我把钥匙弄丢了.英语中,如果你用了yes,后面就一定是肯定句,用了no,就一定是否定句.B项就错了,当然别人钥匙丢了你也不能说C项不客气,更不能说D项你错了.所以是A.
学英语不是一个死的东西,必须学的灵活,灵活运用才是最好的!加油!
