使用比較級(jí)。(錯(cuò))Heismoreclevererthanhisbrother.(對(duì))Heismorecleverthanhisbrother.(對(duì))Heisclevererthanhisbrother.2）要避免將主語(yǔ)含在比較對(duì)象中。(錯(cuò))ChinaislargerthatanycountryinAsia.(對(duì))ChinaislargerthananyothercountryinAsia.3）要注意對(duì)應(yīng)句型，遵循前后一致的原則。ThepopulationofShanghaiislargerthanthatofBeijing.Itiseasiertomakeaplanthantocarryitout.4）要注意冠詞的使用，后有名詞的時(shí)候，前面才有可能有名詞。比較:Whichislarger,CanadaorAustralia?與Whichisthelargercountry,CanadaorAustralia?Sheistallerthanhertwosisters.與Sheisthetallerofthetwosisters.【例題解析】1.Thisboxis___________thatone.
