新36套里面的题目：
Heat pumps circulate a fluid refrigerant that cycles alternatively from its liquid phase to its vapor phase in a closed loop. The refrigerant, starting as a low-Line temperature, low-pressure vapor, enters a compressor driven by an electric motor. The refrigerant leaves the compressor as a hot, dense vapor and flows through a heat exchanger called the condenser, which transfers heat from the refrigerant to a body of air. Now the refrigerant, as a high-pressure, cooled liquid, confronts a flow restriction which causes the pressure to drop. As the pressure falls, the refrigerant expands and partially vaporizes, becoming chilled. It then passes through a second heat exchanger, the evaporator, which transfers heat from the air to the refrigerant, reducing the temperature of this second body of air.

1. According to the passage, the role of the flow
restriction in a heat pump is to
(A) measure accurately the flow rate of the
refrigerant mass at that point
(B) compress and heat the refrigerant vapor
(C) bring about the evaporation and cooling of
refrigerant
(D) exchange heat between the refrigerant and the
air at that point
(E) reverse the direction of refrigerant flow when
needed

Key：C
我选的是B，我觉得从“ Now the refrigerant, as a high-pressure, cooled liquid, confronts a flow restriction which causes the pressure to drop.”这个句子中貌似读出了B的意思...但答案是C...是我定位的不对，还是我的分析有问题？

1# okqishi 定位没错，再多看一句就会明白了
B选项说的是compressor

多谢。

那句话后面还有一句，as the pressure falls, blabla expands blabla vaporized blabla chilled ,这个是重点。。定位了以后题目还是不清楚的话，上下也要看几句话的。

谢谢...

问题的定位词出现在 confronts a flow restriction which causes the pressure to drop
但是可以看到该句直接的因果不过是——→pressure to drop。
选项当中没有任何一个同义表达 那么最应该找到答案的这句没有我们要的答案。

老外的习惯 或者学术文章的习惯 都可能在观点/基本阐述句后面加一个同义表达或者进一步的说明。因此看下句。下句分析之后 发现C为下句的同义表达 肯定C了
再说一点
两句综合浏览完。如果眼滑再扫一遍下面的句子。可以明显感觉到ADE都是无关选项，表达他们的句子也在后面。BC确实易选错 但是从同义表达角度来看 Lz不应该啊。。

确实不应该...
