Question

20．我没有打上出租车，所以没能及时赶到．
I failed to take a taxi，so I didn't arrive in time．

Answer 1

分析 I failed to take a taxi，so I didn't arrive in time．

解答 答案：I failed to take a taxi，so I didn't arrive in time．是说过去的事情用一般过去时，这里是含有由so所以引导的结果状语从句，主句是我没有打上出租车，没有做成某事也就是做某事失败了用fail to do sth，打上出租车 take a taxi故I failed to take a taxi．从句没能及时赶到主语还是I，到达arrive，是实意动词，借助于did加上not构成否定，后面用动词原形，及时in time，故答案是I failed to take a taxi，so I didn't arrive in time．

点评 1．because 习惯上不与 so 连用．汉语习惯上说"因为…所以…"，但英语习惯上却不能将 so与because 连用：因为下雨，所以我们呆在家里．误：Because it was raining，so we stayed at home．
　　正：Because it was raining，we stayed at home．正：It was raining，so we stayed at home．
　　2．（al）though 习惯上不与 but 连用．汉语中可说"虽然…但是…"，但按英语习惯，通常不能说although…but？或though…but：
　　虽然很危险，但我要试试．误：Although it is dangerous，but I will try．
　　正：Although it is dangerous，I will try．正：It is dangerous，but I will try．
