while的使用用法大匯總
我們在學(xué)習(xí)英語的時候常常會碰到的英語單詞，那就是while 了，那么大家知道while 的用法會有哪些呢?你學(xué)完了嗎?下面，小編在這給大家?guī)韜hile的使用用法大匯總，歡迎大家借鑒參考!
連詞“while”具有兩種意義，因此為了避免誤用，使用時需多加注意。
“while”作為連詞來使用的時候，表示“同時性”或“對比性、對立”。根據(jù)文章的內(nèi)容可明確該詞具體表達(dá)了哪一種意義的情況固然存在，但如同下文中所展示的相反情況同樣存在。
The temperature decreased while the growth rate increased.
這句話可產(chǎn)生“溫度下降的同時生長速度加快了”和“與溫度下降所不同的是，生長速度卻加快了”兩種翻譯。
正解是：若要使后者的翻譯成立，“decreased”和“while”之間的逗號必不可少，因此目前的情況下無法直接確定此句的翻譯。
