He is a student at Oxford University,_______ for a degree in computer science.| A．studied | B．studying | | C．to have studied | D．to be studying |
|
答案
| B |
解析
| 动词+ing形式在句子中作状语,可以表示时间、条件、原因、结果、让步、附加说明、伴随等。根据he与study的关系可判断出要用动词+ing形式作状语,表示主动和is a student at Oxford University同时发生的动作。所以选B项。动词+ed形式表示被动。不定式常可用来作状语,表示行为的目的、结果或原因等。不定式的完成式表示的动作先于谓语所表示的动作之前。不定式的进行式表示的动作与谓语所表示的动作同时进行。 |
