问题描述：
don't forget to hold on to your dreams,do you?改错
The number of the taxis in that city are becoming larger and larger.还有这题
IN our hometown there used to have many tall trees
答
1.do you改成will you .
理由:这是祈使句,与时态无关.
2.主语The number,一律用单数.但如果是a number of+名词,要用复数.故这里用is,are 改成is .
3.have 改成be.考察:there be表示"有"的结构.
