句子完成在雅思考试听力部分4个section中均有出现的可能，且难度跨度较大，其最大的特征是句子结构和听力原文相比变化较大，因此考生在定位上会有比较大的障碍，换而言之，对于听力理解的要求增高了。

分析认为，在进行句子填空题的读题时，空前后两边相邻的一些关键信息像介词，连词，动词等是我们着重要关注的，比如and, or, either… or …, both … and …, 等，这些词左右两边的语法结构应该保持一致。

“二合一转述”之“并列关系转述”

并列连词的出现尤为关键，是因为“二合一”转述是雅思听力中最高频的含义转述方式之一，在题目中以and连接为主要形式之一，不管是在平时练习还是考试都需要予以重视。观察一些例子：

【原创范例】(1)There are high-speed trains in Japan and ……….

(2)Float records changes in salinity and ……….

(3)Realists focused on events that were ……… and typical rather than extraordinary.

(4)Some governments encourage the new industry by ………. and offering extra tax breaks.

【范例剖析】看过这四个例子会发现：

第1题中，and左边是"Japan"，因此其右应当是一个“国家”或“地区”。

第2题and左边是名词"salinity"那么右边空同样也是“名词”。

而第3题空右方"typical"是形容词，根据语法结构此处同样是“形容词”。

第4题and左边有by，而右边是offering extra tax breaks,因此我们完全可以推断此处应填“动名词词组”。

【范例原文】 (1) These kind of trains can be found not only in Japan but also in Italy.

(2) It collects all sorts of data, most importantly variations in salinity – that’s salt levels - and the

changes in temperature.

(3) However, as to the Realists, it seems that more emphasis was put on ordinary and typical events, rather than extraordinary or exotic.

(4) Some governments subsidize this technology. While in some countries, you do not have to pay as much tax on the purchase of a hybrid car as you would have to on a regular car. This is generally called a tax break

【范例答案】(1) Italy

(2) temperature 或 changes in temperature

(3) ordinary

(4) subsidizing (the) technology
