问题解答:

我来补答
看你想表达什么了.基本时态是过去时.如果想表达 去年年底 已经完成某事,就用过去完成时,想表达去年年底正进行某事,就用过去正在进行时,以此类推.
再问: 那么这题该怎么做? By the end of last year he_____about 1500 English words. A.learns. B.learned. C.was learning. D.had learned
再答: 下面的题怎么做? 选A,刚才好像没看到有题目,不好意思哈。 You must tell him the news as soon as you____him. A.see. B.sees. C.will see. D.is seeing 下面的题,选D By the end of last year he_____about 1500 English words. A.learns. B.learned. C.was learning. D.had learned 根据的你问题,说明你的时态没掌握好,两个解决办法,一是尽快找看关于时态的语法点,边做题边总结自己的心得。第二是根据语义分析,by```是表示到···为止,从中文就可以判断,一般说到···为止,后面就会说···已经怎么怎么样了。时态中,have done 就是表示已经、完成的意思了。然后根据所给时间,在 将来完成、现在完成和过去完成中进行选择。 做题重量更要重质,加油!
