20、of the chemical is two milligrams in every kilogram of fruit, and experts said the actual dosageis far below that level, as overuse benefits neither farmers nor their fruit.“Overdose may make fruit ripen too rapidly and even rot, and will scorch the skin of fruit, which will harm sales for vendors，”
21、 Luo said.China learned the use of the hormone from the United States and Japan, which is a pioneer in research and use of plant growth accelerators and regulators. Ethephon, an organic compound, is an agricultural plant growth stimulant that is sprayed on 70 or 80 percent ripe fruit after they have

34、al data.DBy providing research results.【答案与解析】本文是一篇议论文。长期以来，人们认为睡觉前喝一杯热牛奶有助于睡眠，但研究表明，只有喝晚上挤的牛奶才真正有助于睡眠。这到底是什么原因呢？快来读文章吧！12B细节理解题。由第四段中的信息“Those given night milkwere less active and less anxious than those fed with the milk collected during daytime”可知，老鼠喝了白天挤的牛奶会更有活力，也更焦虑，故选B项。13D推理判断题。文章中提到晚上挤的牛奶的褪黑
35、激素含量是白天挤的牛奶的10倍，并不是说研究人员在老鼠身上测试了10次，所以A项错误；由第二段中的信息help people feel sleepy and reduce anxiety.可知，褪黑激素不可能使人更加精力充沛，故排除B项；由第二段中的信息“night milkcontains more melatonin”可知，并不是所有的牛奶中都含有大量的褪黑激素，故排除C项；由第六段中的信息“taking melatonin drugs has been suggested to those who are struggling to fall asleep at night”可知，褪黑激
36、素被用于安眠药中，故D项正确。14A标题归纳题。作者在第一段就点明了文章要论述的对象晚上挤的牛奶。在接下来的几段中，作者通过研究人员在老鼠身上做的实验论证了晚上挤出的牛奶与睡眠的关系，所以最适合做文章标题的是A项。15D推理判断题。文章的第二五段都是讲研究人员的实验及其结果，所以作者是用研究人员的研究结果来支持论点的。.七选五阅读(共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。Your children are watching you._16_According to the Health Program，developi
