8、table， a glass of milk seems to be a constant， at least it was when I was growing up.It was widely believed that milk was integral in building strong bones and teeth. Theres no doubt that dairy products(乳制品)，milk in particular， are high in protein and calcium， and most milk products are supplemented
9、 with Vitamin D and A.While its wellknown that our bones need calcium， some studies suggest that high calcium intake doesnt necessarily lower a persons risk for fractures(骨折). A Harvard study found that people who drank two or more glasses of milk had no greater protection from breaking a bone than
10、those who drank a glass or less a week.Theres no doubt that we need calcium. Some antidairy supporters claim that dairy can lead to heart disease. Much of this claim is based on high fat and high dairy products， like cheeses and creams， which may indeed contribute to cardiovascular problems. Some st
11、udies have linked high milk intake with a risk of prostate cancer； this seems to be caused by highfat dairy products， not dairy in general.Although milk was always regarded as one of the most important thing we need for our bones， yet least promoted factors involved in strengthening bones. Perhaps w
12、e should think of dairy as less like a nutrient and more like a food. If you like it， eat it.If not， find some_others. Because some claims may not be completely true.

16、h.阅读表达阅读下面短文并回答问题，然后将答案写到相应的横线上(请注意问题后的词数要求)。1 Some foods can make you sick if they are stored in conditions that are not cold enough to prevent the growth of harmful organisms. Freezing can keep some foods in good condition for months after the growing season. Yet foods can be damaged if they are k
17、ept too cold.2 The British development group Practical Action says the best way to prepare foods for storage is at harvest time while still in the field. Use a sharp knife and place the harvested items on a clean surface or directly into storage containers. Do not put them on the ground. Use clean w
18、ater to remove dirt， and keep the water clean. Usually it is better not to remove outer leaves from fruits and vegetables before storage. _， food can become dry.3 Fruits and vegetables must be cool from field heat before they are put into storage. But cooling them in water can spread fungus(真菌)throu
19、ghout the food. A better idea is to harvest foods either early or late in the day， then leave them to cool naturally. Some fruits and vegetables must be stored at 0 to 4 degrees Celsius. Any colder， and they might be damaged. Some foods need to be stored at 4 to 8 degrees， and some need to be stored
20、 above 8 degrees for best results. Wet the fruits and vegetables so they do not become too dry. The best time to do this is before storage. Cover the items in plastic once they reach the right “critical temperature” for storage. Most fruits and vegetables need the relative humidity(湿度) in storage to
21、 be kept between 85% and 95%.4 Finally， leave space between the food containers and the walls of the cold storage area so air can flow. Keep the space clean. And try not to open the doors too often.21What is the main idea of the text？ (no more than 8 words)_22How should we set the temperature in the

23、s)_课时作业(十二).1.Dsuggest后跟从句时需用虚拟语气，所以排除A、C两项；consult sb. about sth.意为“关于某事请教某人”，所以D项正确。2B考查比较级的用法。句意为：“我们的运动员在北京奥运会上取得了巨大的成功。”“是的，我认为在亚洲没有人表现得比他(她)们好。”否定词和比较级连用表达的是最高级的意思。3B句意为：“布鲁斯，我真的很欣赏你的书法。”“非常感谢。”根据英语习惯，如果对方表扬你，你应该表示谢意。故答案为B。A、C、D三项不符合英语表达习惯。4C考查常用搭配。a limit to sth. “对某物的限制”，其中to不能换成of。5C考查动词辨析。
24、lie on the ground 意为“躺在地上”， lie(躺)的进行式为lying; lie(说谎)的过去式为lied; lay an egg意为“下了一个蛋”。句意为：躺在地上的那个男孩撒谎说他见过一只公鸡下了个蛋。6Ahave sth. done “让某事被；经受”； have her written English improved意为“使她的书面英语有提高”。句意为：詹妮希望史密斯先生能给她提出在短期内快速提高书面英语的方法。7CGo ahead用于回答别人的请求，意为“去吧，好吧，说吧，干吧”。8D考查情态动词的用法。句意为：十一月的合肥通常是温暖而阳光灿烂的，但今年可能会很冷
25、。can表示可能性，其他三项没有这个用法。9A说话人提出自己想在自己的家乡开个餐馆的计划，答话人说“也许提供当地最好的菜肴是个好主意”，由此可推测第一个人是征求对方的意见，故选A。10B考查冠词。句意为：当杰克听说他的文章在学校的杂志上发表的时候，他有一种兴奋的感觉。第一空为泛指；第二空为特指。11B考查情态动词。别人征求意见，答话人说“我认为我们应该做的最重要的是尽量和他们多待些时间”，而不是“不得不”，故排除A而选B。12B考查名词。limit “限制，限度”。parking limit指“停车限制”。句意为：这里有10分钟的停车限制，因此我们必须赶快去取车。13C考查debt短语的用法。
26、 in debt “有债务”；out of debt “没有债务”。句意为：你认为负债的人要比没有债务的人聪明吗？14D考查情态动词的特殊用法，本句是一条禁令。而shall用于肯定句，主语是第一、三人称时，表允许、警告、命令等语气，故选D。句意为：尽管现在周末不上课了，但有些学校的学生没有老师的许可是不允许外出的。15B考查交际用语。Why dont you/we do sth？表示给某人提建议，选项B表示同意别人的提议。.16.D细节理解题。根据第二段的A Harvard study found that people who drank two or more glasses of mil
27、k had no greater protection from breaking a bone than those who drank a glass or less a week.可以推断出牛奶的饮用量和骨折之间没有必要的联系。17D细节理解题。根据第三段的有关信息可以得知文中没有涉及胃癌的问题。18C词义猜测题。根据最后一段Perhaps we should think of dairy as less like a nutrient and more like a food. If you like it, eat it. 可知作者的观点是如果喜欢就吃，不喜欢就吃其他的食品(物)。1
28、9B推理判断题。根据第一段的at least it was when I was growing up 可以推断出作者在小时候是常常喝牛奶的。20A推理判断题。Because some claims may not be completely true.可以得知一些声明并不是完全正确的。.本文主要就如何更好地冷藏食物给出了一些建议。21Some tips for cold storage of foods主旨大意题。纵观全文尤其是第二段第一句“The British development group Practical Action says the best way to prepare
29、foods for storage”可知本文就如何冷藏食物给出了一些建议。22According to different fruits and vegetables.由第三段中“Some foods need to befor best results.”可知我们应该根据不同的食物设定不同的温度，否则的话，食物就会被损害。23Without the leaves句子填空题。由空格前一句“Usually it is better not to remove outer leaves from fruits and vegetables before storage.”可知不要除去外部的叶子，如
30、果没有了这些叶子，食物可能会变干。24To keep them at the relative humidity. / To harvest foods either early or late in the day. / Not to remove outer leaves from fruits and vegetables before storage./ To prepare foods for storage at harvest time./ Dont put the foods against the walls of the cold storage area.归纳表达题。认真查阅全文，便可得到以上答案。25Wet the fruits and vegetables.代词指代题。认真理解画线词所在句便知this指的是画线词所在句的前一句“Wet the fruits and vegetables”。
