1. Have you ever grown any plants? If so, what did you do to grow them? If not, what kind of plant would you like to try growing?你种过植物吗?如果种过的话,你是怎么种植的?如果没有种过的话,你想要尝试种植什么植物?△ If so为省略句式,意为“如果是这样的话”,if用作连词,so 用来代替上文的内容,以避免重复。If not 意为“如果不是这样的话,否则,要不然”,意义与If so 相反。
2. In 1974, he became the first agricultural pioneer in the world to grow rice that has a high output.1974年,他成了世界上第一位种植高产水稻的农业先锋。△不定式放在表示次序的词如the first, the last以及the only, the very, the right, the best等词后面作定语,且与所修饰的名词之间构成逻辑上的主谓关系。
3. Using his hybrid rice, framers are producing harvest twice as large as before. 用他的杂交水稻, 农民种出的粮食是以前的两倍。△“…times as+形容词/副词的原级+ as”为常见的倍数表达法,意为“是……的几倍”。This room is three times as big as that one.这个房间是那个房间的三倍大。知识拓展英语中常见的倍数表达法还有:This room is twice bigger than that one.= This room is three times the size of that one.这个房间是那个房间的三倍大。The output of TV sets in our factory is 15 times that of ten years ago.= The output …is 15 times what it was ten years ago.我们厂电视机的产量是10年前的15倍。
