D2
1. B。文章提到Throughout the 13-day experiment, participants had to stay in a lab with dim (昏暗的) light, which meant that they couldn’t tell the time of day and only ate meals when they felt like it, namely when their body clock told them to.可见生物钟对于人们的食欲是有影响的。
2. C. 根据原文By monitoring the appetite and food preferences (偏好) of the participants, scientists found out how the body clock manages hunger可知实验的目的是为了找出为什么人们晚上容易饿。
3. B。 原文分别提到choosing lower-calorie foods rather than higher-calorie foods in the evening can all help with weight loss.， when you consume food after 8 pm, your body doesn’t break down the calories you take in as effectively as it does during the day和using devices with artificial (人造的) light, such as tablets or smartphones, before bedtime makes it harder for you to fall asleep. “If you stay up later, during a time when you’re hungrier for high-calorie foods, you’re more likely to eat during that time，可见a, c, e三项是正确的。
4. B。根据文章最后一段“Knowing how your body operates will help you make better choices,”可知Shea相信了解生物钟的运作能够帮助人们更好的控制饮食。

1. B。根据第三段的“he lacked the sense of tone and basic rhythm needed to excel”和“it seemed that he just did not have any natural ability”可以得此答案。第一段里作者说自己开钢琴课是为了补贴家用，所以A有误。由第四段的“I told him that the recital was for current students only”可见，作者一开始的时候不想让Robby来参加独奏会，所以C不对。D的“he never succeeded”跟文章内容不符。
2. D。根据第五段的“That way, any damage he would do would come at the end of the program and I would still have a chance to fix it”可以得此答案。
3. D。文章中Robby在钢琴上的天赋不够，但是他为了让在妈妈有一天能听到他弹琴的美妙声音而一直练习，最后弹出了优美的旋律，所以应该是对妈妈的爱和他自己的努力使他最后成功了。
4. C。最后一段里，作者说Robby是她的老师，因为他身上体现了要相信自己，体现了善良又有成功意愿的人值得拥有你给的机会。
