有种题型是个你一个句子,句中一个横线,线边一个括号,括号内一个单词,要你以适当形式填空,比如是一个动词,那什么情况下动词前加to 比如!#¥% (watch)!¥¥ 老师讲的是to watch 还有什么情况下是加ing, It's easy for us (stay)healthy I would love (make)friends sith him 这类的 既然这样,你就把常见的固定,或重要的打出来,
正确答案 It's easy for us to stay healthy.[it's easy for sb to do sth] I would love to make friends sith him.[would love to do sth] 例如 like doing sth enjoy doing sth would like to do sth had better do sth. 有好多呢,我也是初二的,建议你买《蓝飓风英语——至尊钻石语法书》,老师推荐我们买的,挺全的
