雅思閱讀長難句是大家在解答雅思閱讀考試的時候一定要克服的一個障礙，想要準確的分析雅思閱讀長難句，考生需要抓住句子的主幹並理順句子的其他成分。下面大家一起來看看詳細內容吧，看看如何把這些內容應用到實際中。首先，雅思閱讀長難句的閱讀最主要的是抓住句子的主幹。
我們說英文的句子主幹包含了句子本身60%的信息，特別是對於我們不要求精確理解句子，不求甚解的情況下，主幹的把握就更加重要了。因爲，在讀的過程當中我們並不知道這句話是否是我們所要定位的句子，所以，只要大致理解即可。
那麼，主幹到底會出現在什麼地方呢?一般來講，英文講究開門見山，句子的表達也不例外，重要的單詞，重要的信息一般放在句子最前面。也就是說，如果句子開頭即出現名詞，那麼它90%以上就是句子的主語了。
舉例如下：
The unity that should characterize the strong system is developed by affording opportunity for diversity, which appears to be essential if education is to develop in consideration of the needs of children and youth.
這句話一開頭就出現the unity 那麼它就是句子的主語了，而且後面出現that這個信號詞，那就更加證明the unity主語的身份，因爲只有主幹才享有被修飾的權利。
還有一種情況，那就是句子一開始也許出現的是形容詞或是其他的修飾的詞彙，那麼我們一定要往後找到最終的那個名詞，找到了，就是句子的主語。比如：
Popular illustrated magazines rapidly became an important and significant factor to the literate in Australia, who was forming our national image, as were the singers of ballads and strolling entertainers who were also making a major contribution.
這句話一開始是由兩個形容詞開頭popular和illustrated，那麼後面它們所修飾的名詞magazines就是句子的主語了。
The convergence of these two growing trends--- dropping out and logging in--- exacerbates the serious consequences of a drop in political involvement and a rise in social isolation.
這句話是由the convergence of these two growing trends 開頭，那麼這整個名詞詞組就是主語，核心詞彙是convergence。
主語不難找。當主語找到之後接下來就是謂語動詞了。陳述句一般來說謂語動詞在主語之後，但是並不是每個主語後面的動詞都是謂語，因爲一句話主句謂語動詞只有一個(除去並列的謂語動詞)。如果主語後面出現that，where，which，who，when，although等連詞連接的從句，則謂語動詞需要跳過一個，找第二個。舉例如下：
The unity that should characterize the strong system is developed by affording opportunity for diversity, which appears to be essential if education is to develop in consideration of the needs of children and youth.
這句話上面提到過，the unity是主語，後面緊接着是that 因此，我們需要跳過一個動詞即從句動詞characterize，而去找第二個動詞is developed，而後者就是主句謂語了。
第二種情況是如果主語後面出現逗號，一般需要找第二個逗號，緊隨第二個逗號後面的動詞一般就是謂語動詞了。舉例如下：
The SETI institute, a Californian research foundation, managed to raise $ 16 million to fund Project Phoenix, which is using the Australia Telescope at Parks in New South Wales for its search.
這句話the SETI institute作爲主語，後面出現逗號，則需要跳過兩逗號之間的內容，那麼緊隨其後的managed就是謂語動詞了。
主幹中只要找到主謂就大功告成，賓語一般都是非常容易找的。
下面給個更雷的，請大家分析它的主謂賓：
The fact that programs in these languages, although made up largely of English words and some well-known mathematical symbols, are unintelligible to the lay reader indicates the gulf which still exists between the kind of verbal instructions which can be given to another human, and the coded instructions required by the computer.
當找到主謂之後，基本上閱讀這句長句的主要目的已經達到，剩下的內容那就要看我們高不高興看，願不願意看，和看不看的懂了。因爲，除了主謂，剩下的內容就是修飾，而豐富的修飾語向來都是長句必備的.準備給雅思考生的殺手鐗。但是，這些內容需要都看懂嗎?當然不需要，甚至，很多時候根本不需要看。這就要看這句話和題目本身的聯繫了。舉個例子：
1. The unity that should characterize the strong system is developed by affording opportunity for diversity, which appears to be essential if education is to develop in consideration of the needs of children and youth.
還是上面舉過的例子。除了主幹the unity和is developed，剩下的比如用來修飾the unity的that should characterize the strong system,這個從句，我的要求是看你看的懂的詞彙，也就是說挑一些簡單的單詞來讀。這就要主動閱讀。在這句從句中，可以只是讀懂strong system就可以了。一般來說，大多數挑選的單詞都是具體的名詞爲主。
那麼對於修飾語by affording opportunity for diversity, which appears to be essential if education is to develop in consideration of the needs of children and youth 來說，挑一些最簡單的單詞來大致讀懂語言。比如，opportunity, essential education, needs children and youth.只要把以上的單詞大致讀懂，那麼這句話的內容就非常清晰的展現在各位面前。
再舉一例：
Popular illustrated magazines rapidly became an important and significant factor to the literate in Australia, who was forming our national image, as were the singers of ballads and strolling entertainers who were also making a major contribution.
這句話的主幹是magazines became factor.修飾中可以去閱讀的是important, Australia, image, singer, contribution.剩下的不需要去閱讀，只有當我們確定題目的定位點就是這句話的時候，纔會去認真的精讀每一個單詞!
通過上面的分析，大家一定對雅思閱讀長難句中的主謂賓結構有所瞭解了，如果掌握了句子中的這三個成分，那麼這個句子也就難不倒大家了。大家可以在備考雅思閱讀考試的時候，針對這些內容進行適當的練習。
