Health A good night's sleep Do you get the sleep you need? When the morning sun looks in through our window， do you jump out of bed or go on lying? Having enough sleep can make the difference between a great day and a terrible one! Here are the tips for a good night's sleep: First， go to bed and get up at the same time， even if you haven't gotten a good night's sleep. Sleeping late for just a few days can change your body clock to a different cycle. Also， avoid big meals at night. Eating heavy rich food within two hours of bedtime can keep you awake， Your stomach works hard because of those fatty foods， and that may keep you up. Your body produces a chemical called melatonin that helps you sleep. Light changes the amount of melatonin. It produces more in the evening and less in the daytime. So at night turn off your TV and PC. Also， don't read from abacklit device(有背光的设备) like an iPad. Some scientists think that the light from those devices stops your body from making melatonin. So turn those screens off at least an hour before bedtime. After a good night's sleep， you'll be able to face a new day.

试题分析：本文主要介绍了芒果的功能，吃芒果对人的好处，以及怎样才能拥有高质量的睡眠。

1.D考查推理判断题。根据“The countries of India and the Philippines have named mango their national fruit” 可知A选项是错误的。“A cup of the fruit has only 100 calories and is nearly fat-free”可知B选项是错误的。根据 “Mangoes have over 20 vitamins and minerals， making them a ‘super food’.”可知芒果不是有各种各样的维生素，只有20多种维生素和矿物质，C是的错误。根据 “And not only do mangoes taste great but they also are good for you.”可知D选项是正确的。

2.C考查推理判断题。根据 “It produces more in the evening and less in the daytime.” 和 “Some scientists think that light from those devices stops your body from making melatonin. So turn those screens off at least an hour before bedtime.”两句得知答案为C。

3.考查推理判断题。这两篇都带有一定的科普性质，介绍芒果以及如何拥有好睡眠。所以故事书和指导书，新闻报导这些都不是很符合句意，很有可能是杂志上的文章。故选B。

考点：考查科普类短文阅读。
