上海之鱼:when Mike wsa four, he was able to rides the bike.怎样改错

rides----ride

be able to do sth.能够做谋事

When Mike was four, he was able to ride the bike.
am is和are的过去形式分别为am is改为was ,are改为were
be able to do有能力做某事,这里的do一定要是动词原形,able 就是能够的意思.
整句话的中文解释就是:当迈克四岁的时候,他就能够骑自行车了.

be able to do sth = can do sth表示能够做某事．后面接动词的原形，所以句子中的rides要改成ride.

be able to
看到这个to了吗？
to的后面动词要用原形哦
怎么用了第三人称单数呢？
另外，首字母没大写，was拼写错误，一般是不会作为要改的错出在题目里的（哈哈，应该是你打错了吧）
如果有两个错误的话，那么the 也不当
因为the表示特指，用the 就表示他会骑某辆特别的车。所以，如果上下文没有提到那辆特别的车，应该用a 比较妥当。
当然，这也算不上是严格的语法错误。不过在上下文都没有提到那辆特别的车的情况下，这个地方还是可以改出来的。

was拼错了
be able to do
