1.A new system of quality control was brought in to overcome the defects in the firms products.
A) invested B) introduced C) installed D) insisted
答案及解析:B. 解题思路:借助画线短语核心词(bring)的基本含义带来/引起,并借助与画线结构相直接相关的结构含义(质量控制系统被。。)判断B是答案。
Invest: vt.(常与in连用)投入(资金,精力,时间等)
e.g. Ive invested a lot of time and effort in this plan.
我已在这计划中投入了大量的时间和精力
insist: vi, vt(常与on, that连用)主张;坚持, 坚持要求
e.g. We insist on / upon self-reliance.
我们坚持自力更生。
e.g. We all insist that we not rest until we finish the work.
大家都坚决要求不完工就不休息
2.Techniques to harness the energy of the sun are being developed.
A) convert B) store C) utilize D)receive
答案及解析: C. 解题思路:被选项是动词时关注所给句子中的空格后续结构,因此关注原句中的宾语:the energy of the sun(太阳能)。被选项中:convert通常用在convertinto的结构中,而原句中没有这样的结构,所以排除A;而根据句意凭借常识store(储存)和 receive太阳能不是刚发展的新技术,所以也排除掉。答案为C。
