1.B 2.A 3.C 4.B 【解析】 【原文】 W: Last year our school entered a science fair. Our teacher gave us a few ideas and then we had to design a scientific experiment. We were divided into teams and had to decide which field we would work in, like chemistry, physics or biology. Our teacher suggested looking for more ideas in science magazines and books, but I’d rather get the information online. My family home has a big garden and I like helping my father grow vegetables. So my team decided to focus on how the weather affected the growing process. We had to make our experiment as specific as possible, so we decided to think about whether the amount of rain received made a difference to the vegetable size. Then we began to design our experiment. Our teacher pointed out that a single experiment wouldn’t be enough to prove our theory. He suggested doing the experiment at least three times but in the end we only had time to do two. When we’d written up each part of the process, we had to design a display for the fair. We tried our best to present our information as well as we could. What’s more, we’d taken lots of photos - none of the other teams did that! Finally, we came third in the competition which was great! It was just a really interesting project and I learned so many new things.
