Please help me!Correct the mistakes in the following sentenc

1。The more he said,the less convinced he was for he couldn't make his points clear。把convinced改成convincing,因为后面这个才是有说服力的意思,前面那个意思是他被说服,语态不对。2。Death awaits for all men。去掉介词for,因为await是及物动词。3。The dean opposes to the idea。此句正确4。Supposed that there was a road accident involving one,or perhaps two atomic cars and that its protective covering were damaged。改supposed为suppose,这样就成为一个句子了。另外去掉atomic cars and后面的that,后面是一个独立的句子,不需要that来引导。5。Don't release the news in the public。改in为to6。We should be economic of time,money and food。economical才有节约的意思,economic是经济学上的意思,因此用前者。7。if we have enough money,we are well on the way to the experiment。如果将此句看为虚拟语气,则后面一句改为we should have been well。。。如果将此句看为条件状语,则后面一句改为we will be well。。。8。Gravity keeps it rock for ever。rock改为rocking keep sb doing sth9。The explosion of an atomic car equals to that of a small atomic bomb。此句正确10。you can use this umbrella in case raining。in case of是固定用法,此句少了介词of。
