1____of large mammals once dominated the North American prairies: the American bison and the pronghorn antelope.
A There are two species
B Two species
出自ETS真题1套13题
2____main process ...
前两个题都是一样的考点其实就是考你谓语动词的判断,第一个题中的dominated是谓语因为如果是过去分词作后置定语的话他后面不能跟宾语。同理第2个中的involved不是谓语因为involve不及物,固定搭配时be involved in 他缺少be因此是过去分词作后置定语。
第3题选 it is 3 years since ....因为其一这是固定搭配,其二是因为时间,距离,金钱,天气的代词用it。
