1.In the dream,he grew a new type of rice that was as big as a peanut.

◆本句含有由that引导的定语从句。that was as big as a peanut作rice的后置定语。

◆“as+形容词/副词原级+as…”意为“与……一样……”。“not so+形容词/副词原级+as…”意为“不如……”。

2.The plant allowed farmers to rest in its shade.

allow为及物动词,意为“允许,准许,让”,allow sb. to do sth.意为“允许某人做某事”,动词不定式作宾语补足语。

(2)allow doing sth.允许做某事。

3.In the 1960s,a few years after he finished his studies in agriculture at university,he came up with an idea for hybrid rice.

◆in the 1960s意为“在20世纪60年代”。表示“在……世纪……年代”时用介词in,在整十的年代后加“s”或“‘s”,并在年代前加定冠词the。

◆a few意为“一些,几个”,用于可数名词复数前,相当于several或some,表示肯定概念。few意为“很少,几乎没有”,表示否定概念。

当主语前面或后面跟有with,together with,like,except,but,rather than,as well as等构成的短语时,谓语动词与主语保持一致。

6.The introduction of this new product made China a leader in rice production.

make China a leader为“make+宾语+名词”结构,名词作动词make的宾语补足语,这种结构表示“使/让某人成为……;使某人当……”。

9.Because of Dr. Yuan’s hard work,China now produces enough rice every year to feed its people.
