Thank you. And where can I get a pushcart?

谢谢，请问哪有手推车呢？

But he didn't have a truck, so he built a pushcart.

但是没有卡车，所了一辆手推车。

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

好吧，我们知道我一样在西北大学用手推车上的显微镜创造循环经济。

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

我还常常和母亲一道去位于第70和76街之间的第二大道两边的手推货车市场买东西。
