[阅读选择]Helping the planet is a big part of what our world trip is all about and that‘s exactly what we did this past week. We helped get a hydroponics farm started in a local village. This farm will be a model for the local villagers so they can start their very own self sustaining farm. Hydroponics is a type of farming that uses a third of the water needed in an average farm and uses no soil.
A hydroponics farm _______________.
A、is difficult to build
B、is a type of farm without soil
C、will cost lots of money
D、was started in the village before they came
答案解析：答案选B。词义了解题。依据关键词hydroponics farm迅速锁定本段。再经过扫除法能够判定B项是正确的。因为A和C表述的内容文章并没有提到过。D项表述是错误的，因为那个村庄在他们去之前并没有这种hydroponics farm。是他们到了之后，协助树立了一个模型。
