解析:第一题有的同学一看he做主语就用了is,忽视了will后应加动词原形。我们在写句子时,很容易把动词丢掉,英语句子里,动词不能少的规律必须要牢记。第二题中to后加动词原形,而不是用单三人称.。
二、be going to +动词原形与will+动词原形用法不清楚
例:我正努力学习,准备参加英语考试。
I am studying hard and I will try for my English exams.
答案:I am studying hard and I am going to try for my English exams.
解析:be going to 表示计划、打算要做某事。E.g. He is going to visit his friends. 还表示某种迹象表明会发生某事.e.g. Look at the clouds. Its going to rain. 而Will+动词原形 指对将来事物的预见、表示意愿、决心。E.g. I will wait for you until you come. 在单纯预测未来时,二者可以互换,但在此题中只能用be going to,而不能用will。
自主检测:
