Question

They can play basketball very well 同义句转换

Answer 1

They are able to play basketball very well.
情态动词can相当于be able to，但后者时态比较多，比如一般将来时与过去将来时，一定是will be able to，would be able to，现在完成时和过去完成时是have/has been able to和had been able to，所以，当直接引语情态动词为could（can的过去式），而引述动词又是过去时时，这里的could要变成had been able to，比如：
James said, "I'm sorry thatI couldn't fix your computer yesterday."
James told me that he was sorry that he hadn't been able to fix my computer the day before.
