2016年雅思考試閱讀轉(zhuǎn)折詞的運(yùn)用

　　轉(zhuǎn)折信號(hào)詞

　　轉(zhuǎn)折信號(hào)詞的作用是否定前項(xiàng)肯定后項(xiàng)，使前后兩句話的方向或意思相反。表示轉(zhuǎn)折關(guān)系的信號(hào)詞有：but，yet，however，whereas，in fact，on the contrary，conversely, on the other hand等。

　　公式: A (正/負(fù))， but B (負(fù)/正)

　　應(yīng)用: 在閱讀前半句時(shí)就可以預(yù)測(cè)后半句的大意，使接下來(lái)的閱讀過(guò)程變成求證，如同把文

　　章讀了兩遍。另外，在有生詞的情況下，只要理解了半句話的意思，就可以推測(cè)另一半句子的含義。例如1：

　　The second flaw in the reasoning of the WZCS ( The World Zoo Conservation Strategy )document is the naive faith it places in its 1,000 core zoos. One would assume that the caliber of these institutions would have been carefully examined, but it appears that the criterion for inclusion on this select list might merely be that the zoo is a member of a zoo federation or association. This might be a good starting point, working on the premise that members must meet certain standards, but again the facts don't support the theory.

　　題目 Zoos in the WZCS select list were carefully inspected.(判斷題)

　　例如2：

　　The Aborigines made no use of Leptospermum or Dodonaea as food plants, yet the early settlers found that one could be used as a substitute for tea and the other for hops.

　　例如3：

　　From the mid-1960s when 'the Green revolution began, Asian food production doubled through a combination of high-yielding crops, expanded farming area and greater intensification. However, a mysterious threat is emerging in the noticeably declining yields of rice.
