A.are introduced B.are being introduced C.were introduced D.were being introduced
2.I think much attention____your pronunciation.
A.should be paid of B.ought be paid by C.must pay to D.should be paid by

1.C
我认识布郎先生,我们是在国际会议上认识的
由at an international conference可以判断这个句子表达的是过去式排除AB,且为被动语态(我们被介绍),答案D表达的是被动语态的进行式,表过去某段时间正作某事,本句仅单纯表达过去的一个动作而已,没有某时我们正在被介绍的意思.因此排除D
2.A
我认为你应该注意你的发音
也是被动语态的问题排除C,B应该是OUGHT TO也可排除,此句I THINK是插入语可去掉不看.若为D,则动作的执行者是你的发音,而实际上应该是你这个人所以排除D
我打字好慢哦都累死了你就把分给我吧,呵呵```^-^
