Thank you. And where can I get a pushcart?

谢谢，请问哪有手车呢？

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

但是他没有卡车，所以他做了一手车。

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

好，知道如何像一样在西北大学用手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.

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货车市场买东西。
