the pick of the crop

Instead of using the ancient solar energy locked up in fossil fuels, we are trying to take advantage of the carbon dioxide and modern solar energy that crop plants pick up.

我们将不再利用储存在化石燃料中的远古太阳能，而是尝试着利用植物吸收的二氧化碳与现代太阳能。

A lot of the kids would tassel corn, pick cucumbers or whatever crop was ripe for the picking.

很多小孩在农场掰玉米，摘黄瓜，收获任何成熟的农作物。

People feel wary of this - that they will disrupt the crop - but not if you pick mostly male flowers and leave the female flowers, with a small courgette forming behind the flower to grow on.

人们会担心——把作物毁坏了——但如果你采的大多是雄花，留下雌花，雌花后面都带有小胡瓜，就没有关系。
