We learn through books and the Internet, neither of which are dispensable.
learn through 通過.來學(xué)習(xí)
dispensable (因并不真正需要而）可省去的,可丟棄的,可有可無的.
再看看你給出的句子：We study by two things that are books and internet.主要錯(cuò)在一處：two things 和books and Internet是同位關(guān)系,后面一項(xiàng)“books and Internet”是前項(xiàng)“two things”的同位語(yǔ),兩項(xiàng)表達(dá)同一事物,是并列的,但你卻使用了定語(yǔ)從句的句式,不妥.你可以修改為：We study by two things： books and internet. 用冒號(hào)來引出two things的同位語(yǔ).但在此處我給出的句子中：“neither of which are dispensable”卻是“books and the Internet”的定語(yǔ)從句,注意與同位語(yǔ)的區(qū)別.
舉個(gè)例子會(huì)可能有助于你加深印象：
Mr. Smith, our new teacher, is very kind to us.
我們的新老師史密斯先生對(duì)我們很好.
our new teacher是主詞Mr. Smith的同位語(yǔ),指同一人.
當(dāng)同位語(yǔ)是一個(gè)句子時(shí),樓主可以上網(wǎng)搜搜同位語(yǔ)從句與定語(yǔ)從句的區(qū)別,它們有點(diǎn)相像,注意區(qū)別.
