A.although B.as long as C.as far as D.unless
不要光给个答案.
第三题 答案给的是as long as 为什么啊

答案

1.born此处意思为“天生的”；这个词很常用,后面常跟“-er”表人或职业的名词,比如：He is a born baller.他天生就是个打球的.D的问题就在于它首字母是元音发音,所以前面的不定冠词要用an.
2.There's no doubt about it.毫无疑问.是口语中常用的句子；这里把no换成not much表示“没多大问题”.No problem常用来回答请求或建议,比如：-Can u shut the windows for me?你能帮我关下窗户么?-No problem.没问题.相当于“I have no problem to do it.”
3.我选B.回答这题首先要明确keep sb awake 的意思,awake表示的是一个not sleeping的状态,也就是说keep sb awake的意思是让某人处在一个非睡眠状态下,使某人醒着；所以这里用as long as“只要”,全句意思是：只要咖啡不让我整晚睡不着,我就看不出它有什么害处.
