雅思寫(xiě)作考試中，因果關(guān)系的表達(dá)常常難倒很多考生，本文中，新東方在線劉美娟老師精選雅思常考話題，將雅思寫(xiě)作中因果關(guān)系表達(dá)的干貨做了詳盡整理，希望對(duì)大家備考雅思有幫助。
雅思大作文中有一類(lèi)題目是因果關(guān)系類(lèi)，具體包括三小類(lèi)：cause and effect、cause and solution、problem and solution。這三小類(lèi)問(wèn)題也可以穿起來(lái)，即針對(duì)某個(gè)topic的cause—effect (即problem) – solution。
無(wú)論哪種題目，寫(xiě)明因果關(guān)系很重要。關(guān)于因果關(guān)系的表達(dá)同學(xué)們都很熟悉，無(wú)非是BS(because / so)，而且大家也一定很清楚的知道BS在英語(yǔ)中，用了前者就不能用后者的道理。例如：
ü Because further education has become more accessible for a wider range of people, an increasing number of people have degrees.
ü Further education has become more accessible for a wider range of people, so an increasing number of people have degrees.
但是除了BS之外，還有很多其它表示因果關(guān)系的表達(dá)，具體如下：
Because系列(表原因)：
1. because of : because后接的是一個(gè)句子(主謂賓);because of 后一般直接跟名詞。例如：
ü Because of the increasing number of machine—and as we noted before, machines magnify human effort—then anyone using a machine can get a higher wage than anyone not using a machine.
2. as / since(除了“因?yàn)?ldquo;外，還有”自從”的意思，使用時(shí)要注意避免歧義)
ü Hours spent on commuting, traffic jams, and fights for parking should diminish, sinceworkers make fewer journeys or work staggered hours.
ü Unfortunately, as the number of people living in the city increases, so do the different problems associated with population growth. (注意此句中的so不表示“所以”，而是“…也…”的意思)
3. thanks to(positive situations通常適用于結(jié)果好的時(shí)候)
ü Thanks to new technology, it's easier than ever to work remotely.
due to (negative situations通常使用與結(jié)果不好的時(shí)候)
owing to / attributable to /on account of.
ü Due to /… / On account ofextreme weather conditions, damage to property occurs.
4. 當(dāng)原因需要的表達(dá)較多時(shí)，我們還可以把以上表達(dá)改寫(xiě)為原因狀語(yǔ)從句，使用thanks to the fact that / due to the fact that /owing to the fact that或者on the grounds that ,,,
ü Will we live longer merely due to the fact that / on the grounds that technology, if implemented properly, will take stress away from our lives
5. caused by /result from也表原因
ü Many car accidents were resulted from / caused bya lack of guardrails
