地球上有许多动物和植物。onearth意为“究竟”e.g.Whatonearthareyoudoing?你究竟在干什么？3.Oceanscovertwothirdsoftheearth’ssurface.twothirds三分之二分数的表达方式：分子用基数词，分母要用序数词；当分子大于1时，分母要用复数。如：threefourths意为“四分之三”。e.g.Threefifthsofthestudentsinourclassaregirls.

我们班五分之三的学生是女孩。当分数作主语时，谓语动词的单复数由后面所接的名词决定。如果是不可数名词，谓语动词用单数形式；如果是可数名词复数，谓语动词用复数形式。e.g.Onlyonesixthofthewaterisclean.

仅有六分之一的水是干净的。4.Somelandisrichwithgreenforests,freshwater,andgoodsoil.berichwith...富有…… 同义短语：berichin...e.g.Someplacesarerichwithallkindsoffruits.

round?befullof意为“装满；充满”，后面通常跟名词，主语可以是人，也可以是物，表示状态。e.g.Sheisfullofjoyafterhearingthegoodnews.
