题型：不详难度：来源：
Once your business becomes international, _____ constantly will be part of your life.| A．you fly | B．your flight | | C．flight | D．flying |
|
答案
| D。 |
解析
| 由于空格后出现了constantly这一副词，这就说明不能选B或C，因为B、C均为名词，不能受副词 constantly 的修饰。A和D均是可能的，因为其中有动词 fly。但若选A，you fly 是一个主谓结构，与其后的谓语 will be 相冲突，所以只能选D，即动名词flying在此用作主语。 |
