11.What will you do if you can't eat everything bought in the canteen?(16)D.According to a survey,what students waste every year could feed over 10million people.
(17)A.According to Xinhua News Agency,the food wasted by Chinese people is about 50million tons of grain every year,which could feed 200million people.
Food waste,which has become a global issue,serves as a mirror that reflects various cultural and social issues in different countries.In the West,for instance,consumerism,the belief that it's good to use a lot of goods and services,is often to blame for food waste.(18)G.Chinese people are well known for being hospitable and generous.Many even feel that they lose face if their guests have eaten all the food.On campus,a generation of single children is less aware of the food waste issue.Students nowadays are well protected by their families and hardly have any concept of how much toil others go through in order to provide them with the food they eat.
(19)F.There are 925million hungry people in the world.They don't have enough food to eat.And farmers work very hard to grow the crops.(20)B.It's also important that everyone thinks about how they can do their bit to reduce food waste.Recently a campaign against food waste launched on line in China might make you think twice about being so wasteful.

A.But canteen waste is merely the tip of the iceberg.
B.So we shouldn't waste our food.
C.Students can never realize the serious food waste situation.
D.Most of us would simply throw away any leftover food.
E.Students waste is extremely serious.
F.To reduce food waste is a big task,and it needs time.
G.China,in turn,features its own eating culture.

分析 文章主要讲的是浪费食物的现象.学生往往会把吃剩下的饭菜倒掉,学校食堂的浪费现象只是冰山一角,我国每年浪费的粮食有大约两千万吨.

解答 16-20 DAGFB
16.D 上下文语境.根据第二行"what students waste every year could feed over 10 millio n people"可知,学生们会把吃不完的饭菜倒掉,由此造成的浪费能够养活一千多万人,故选D.
17.A 上下文语境.根据"the food wasted by Chinese people is about 50 million tons of grain every year,which could feed 200 million people"可知,中国人浪费掉的粮食能够养活两亿人,说明食堂的浪费现象只是冰山一角,故选D.
18.G 上下文语境. 根据本段首句"Food waste…serves as a mirror that reflects various cultural and social issues"和"Chinese people are well known for being hospitable and generous.Many even feel that they lose face if their guests have eaten all the food."可知,食物浪费现象反映一个国家的饮食文化和习惯,故选G.
19.F 上下文语境.根据"There are over 925 million hungry people in the world,most of whom live in underdeveloped countries and areas."可知,本段讲的是处于饥饿中的人们,故选F.
20.B 上下文语境.根据"Many children die for lack of nutrition each year…And farmers work very hard to grow the crops."可知,世界其它地方的孩子因饥饿而死,而且农民种粮食很辛苦,因此我们没有理由浪费粮食,每个人都应该想一想该怎样减少食物浪费,故选B.

点评 七选五题型看似简单,实际上有时完全作对并不容易,需要方法和分析能力及足够的耐力,有必要进行专门练习.首先,快速浏览一遍七个备选答案,先确定哪个选项适合放在文章的什么位置.其次,快速浏览文章,确定文章体裁,抓住文章结构,分析篇章结构,找出各段的主题句或主旨大意.其三,注意各选项中出现的句子衔接手段,寻找句中衔接标志词,七选五备选答案中有两个多余的选项,会对文章中两个空的选择构成干扰,这时要特别细致地比对相似选项.最后,用代入法,检查答案是否合理,将所有选择答案放回空白处,通读全文,检查文章内容是否语义连贯合理、紧扣主题,语篇结构是否通顺连贯、具有一致性、合乎逻辑,写作思路是否清晰明了,格式以及用语是否恰当贴切,从而判断选择的答案是否正确.

"It's also best to buy a few cheaper presents rather than one big one.Part of the fun is the mystery and unwrapping,so it will last longer if you give them several to enjoy."
