问题描述：
1、If the evidence shows that there are more cars runningon the road today than before,.
2、the number of cars has doubled in the past ten years,making riding bicycle on the road become dangerous.
不对该怎么改,最好能重语法角度解释下,
问题解答：
我来补答
第1个句子改为：
If evidence shows that ...
evidence shows "证据表明",其中evidence 是不可数名词,相当于information,且是泛指的,故不用定冠词the
第2个句子改为：
..,making riding a bicycle on the road dangerous
make sth.+ 形容词（作宾补）,所以删除become；riding bicycle 之间应该有不定冠词a
再问： make是表语吗？ 楼下有人改为the number of cars has doubled in the past ten years, which has made riding bicycles on the road become dangerous. 这里的become要去掉吗
再答： make 不是表语。 在句子中，making 表述伴随，后面跟宾语riding a bicycle，然后是宾补dangerous
再问： 楼下有人改为the number of cars has doubled in the past ten years, which has made riding bicycles on the road become dangerous. 这里的become要去掉吗
再答： which has made = making，但书面表达以简洁为原则，所以 making 更好。 become 属于多余。例如： We are trying to make our country more beautiful. 在more之前可以加上become，但是实际上没有必要。
