镜像法巧解雅思阅读判断题

　　原文：While the global economy has been expanding at a bit over 3% a year, the volume of trade has been rising at a compound annual rate of about twice that.

　　原文写的是世界经济增长3%每年，但是trade增长的是2倍于这个速度。

　　所以出现的是题干原样，所以是正确

　　19.Cheap labour guarantees effective trade conditions.

　　镜像：Cheap labour does not guarantee effective trade onditions.

　　题干原样是说cheap labour可以保证effective trade conditions.

　　它的镜像就是cheap labour 不能保证effective trade conditions.

　　原文：Cheap labour may make Chinese clothing competitive in America, but if delays in shipment tie up working capital and cause winter coats to arrive in spring, trade may lose its advantage.

　　原文写的是cheap labour有可能让中国的衣服有竞争力，但是也有可能最终失去优势。所以就是cheaper labour不能保证

　　effective trade conditions，所以出现的是题干的镜像，所以是错误。

　　20.Japan imports more meat and steel than France.

　　镜像：Japan does not import more meat and steel than France.

　　题干原样说是Japan比France进口更多的肉和钢铁。

　　它的镜像就是Japan不比France进口更多的肉和钢铁。

　　原文：At the turn of the 20th century, agriculture and manufacturing were the two most important sectors almost everywhere, accounting for about 70% of total output in Germany, Italy and France, and 40-50% in America, Britain and Japan.

　　原文写的是农业和制造业占德国、意大利和法国总产量的70%，占美国，英国和日本的40%-50%。既没有出现原样，也没有出现镜像。所以是NG。
