Thank you. And where can I get a pushcart?

谢谢，请问哪有手推车呢？

I used to go shopping with my mother in the pushcart markets that lined both sides of Second Avenue from 70th Street to 76th.

还常常和母亲一道去于第70和76街之间的第二大道两边的手推货车市场买东西。

OK.So we know how to create a circular economywith a microscope on a pushcart like me at Northwestern.

好的。们知道如在西北大学那样，用一辆手推车上装着显微镜来创建一个循环经济。
