题型：不详难度：来源：
Kids _________ use the computers to draw in the future.| A．can | B．could | C．will be able to | D．will can |
|
答案
| C |
解析
| can和be able to都表示能力，意思上没多大区别。can表示一般的能力，可以指本来就有的能力。be able to 表示“具体的能力”（即在某具体场合成功地做了某事），强调通过努力。时态区别：can只有现在和过去时，而be able to则有更多的形式。在谈论将来有能力做某事。我们用will be able to。 |
