题型：不详难度：来源：
A communicative satellite ______ as much as 3.5 tons was sent up into space last week.| A．weighing | B．weighed | | C．to be weighed | D．being weighed |
|
答案
| A |
解析
试题分析：考查分词做定语。本题中的现在分词短语weighing as much as 3.5 tons修饰名词satellite,做定语；因为weigh与satellite构成主动关系，故使用现在分词的形式。句意：一颗重达3.5吨的通信卫星上个星期被送上了太空。故A正确。
点评：考查分词做定语。当分词做定语的时候，如果构成分词的动词与名词构成主动关系，就使用现在分词做定语；当二者构成被动关系，使用过去分词做定语。单独的一个分词做定语要放在名词的前面，分词短语做定语要放在分词的后面。 |
