1(英语):Because it's raining hard,we did't go to library.(改为同义句) ( )( )the( )rain,we did

1.同义句:because of the heavy rain ,we didn't go to the library.
because后面接句子,而because of 后面是接短语,它们是可以互换的.it's raining hard说明雨下的很大,通常说雨大的词是heavy,而不用hardly,hardly是几乎不的意思,有否定含义,不能修饰雨大.
2.G=F-G物,这是公式的,所以49000N-4000N=45000N
