On Food Safety
In recent years, the simple joy of eating has been dampened by a string of food safety scandals. The problem of food safety has become a hot issue across the society.
In my opinion, there are two main reasons behind this undesirable phenomenon. First and foremost, lured by huge interests, a number of unscrupulous businesses break the law to make fake commodities or products of poor quality. Besides, the supervisory role of laws and regulations has not been executed in a strict way.
In view of the seriousness of the problem, effective measures should be taken before things get worse. Firstly, the government should intensify the supervision of the food market to ensure the safety of food sources from bottom to top. Secondly, tougher laws should be drawn up to punish those counterfeiting individuals and corporations, and to prohibit them from entering the food industry again. Thirdly, we ordinary people should also be alert to the food quality and expose food safety scandals around us on new media platforms when necessary.
In conclusion, I am firmly convinced that through our joint efforts the problem of food safety will be tackled successfully in the near future.

2.【C1】
J
解析：空格位于定语从句的引导词that之后，该从句缺少谓语动词，且先行词an experience为空格处谓语动词的逻辑主语，同时根据主句时态可知，此空应填入动词第三人称单数形式。根据下文的a waking experience可知，做梦时的经历在很多方面与清醒时的经历相似，故空格处应填入resembles，意为“类似，与……相似”。
3.【C2】
G
解析：空格位于系动词is之后、状语of course之前，应填入形容词。根据上文可知，句中it指代的是experience，而下文转折词but后说“这个经历是真实的”，可知该空格填入的形容词应与real语义相反，故应填入imaginary“想象的，虚构的”。
4.【C3】
H
解析：空格位于系动词are之后、介词by之前，根据上下文判断，该空格处应填入动词过去分词，构成被动语态。由本段大意可知，此处作者是介绍睡眠中的脑部活动，即梦境是通过大脑中的高频电活动显示的，故空格处应填入indicated“显示，表明”。
5.【C4】
K
解析：空格位于shown后的宾语从句中，其后是名词activity，故应填入形容词作定语。上文提到，在睡眠研究中，梦境是通过大脑中的高频电活动显示的，而此处but之后出现转折，指出在非快速眼动睡眠期间，也会出现——活动。由副词also及备选形容词可知，空格处应填入similar，表示在非快速眼动睡眠期间也会出现类似活动。
6.【C5】

解析：空格位于助动词have之后，故应填入动词过去分词，与have构成现在完成时。备选的动词过去分词中只剩expressed和formed符合要求。作者提到，在《梦的解
