Many countries have sent up man-made satellites into space.
这种题目要找准主语,宾语.将原来的宾语变为主语,主语变为宾语,并将原来的被动态动词词组变为被主态动词词组.恩。、你可以就这个问题给我具体给分析下么。。?、这个句子中,Man-made satellites是主语。变主动时,Man-made satellites应该用作宾语,many countries用作主语。同时把被动态动词词组 have been sent up变为主动态词组have sent up。恩。?我是想问。、被动态动词词组该咋样改为主动态词组。。。、被动语态的基本形式有以下几种: 1.一般现在时 is\am\are+P.P(过去分词) 2.一般过去时 was\were+P.P 3.一般将来时 will be+P.P 4.现在进行时 is\am\are+being(固定不变)+P.P 5.过去进行时 was\were+being(固定不变)+P.P 6.现在完成时 have\has been+P.P 7.过去完成时 had been+P.P变为主动态只需要把Be或者Been去掉,把动词过去分词变为原型即可,当然动词变化的时候要注意时态以及单复数的变化。
