A liquid 這是主語 that might be a poor conductor定語從句修飾liquid when it is pure省略了it is的狀語從句 is often used to make謂語 solutions賓語 that readily transmits electricity.定語從句修飾solutions 因?yàn)閟olutions是復(fù)數(shù)的,所以transmits不對(duì),應(yīng)該是transmit 整句話的意思是:當(dāng)一種液體處在純凈狀態(tài)時(shí)會(huì)成為一種弱導(dǎo)體,經(jīng)常被用來制作可以穩(wěn)定導(dǎo)電的溶液。
托福改錯(cuò)題
你這個(gè)是正確的句子吧。就應(yīng)該precisely放到controlled前面 原句不是這樣的哦: Certain types of computers work properly only in environments with controlled precisely temperatures.
