题目内容
【题目】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。
Everyone knows that fish is good for health. 【1】 But it seems that many people don’t cook fish at home. Americans eat only about fifteen pounds of fish per person per year, but we eat twice as much fish in restaurants as at home. Buying, storing, and cooking fish isn’t difficult. 【2】 This text is about how to buy and cook fish in an easy way.
【3】 Fresh fish should smell sweet: you should feel that you’re standing at the ocean’s edge. Any fishy or strong smell means the fish isn’t fresh. 【4】 When you have bought a fish and arrive home, you’d better store the fish in the refrigerator if you don’t cook it immediately, but fresh fish should be stored in your fridge for only a day or two. Frozen fish isn’t as tasty as the fresh one.
There are many common methods used to cook fish. 【5】 First, lean it and season it with your choice of spices(调料). Put the whole fish on a plate and steam it in a steam pot for 8 to 10 minutes if it weighs about one pound. (A larger one will take more time.) Then, it’s ready to serve.
A. Do not buy it.
B. The easiest is to steam it.
C. This is how you can do it.
D. It just requires a little knowledge.
E. The fish will go bad within hours.
F. When buying fish, you should first smell it.
G. The fats in fish are thought to help prevent heart disease.
【答案】
【1】G
【2】D
【3】F
【4】A
【5】B
【解析】
试题分析:文章主要介绍了一些买鱼和烧鱼的常识。带有强烈气味的鱼不新鲜,最简单的方法是蒸鱼。
【1】G考查上下文串联。第一句“Everyone knows that fish is good for health.”是总写,But表示转折,说明but前面一句是对第一句的解释,G项“鱼中的脂肪有助于预防心脏病”符合语境,故选G。
【2】D考查上下文串联。题目前一句“Buying, storing, and cooking fish isn’t difficult.”可知,购买,存放和烧鱼并非难事,再根据后面一句可知,文章主要介绍了买鱼和烧鱼的简单知识,D项“这仅仅需要一点知识”符合语境,此题容易与C项混淆,C项后面应该直接跟烧鱼的方法,即C项与后一句重复,故选D。
【3】F考查上下文串联。根据“Fresh fish should smell sweet”可知,本段讲的是买鱼的时候要闻一下鱼的气味,故选F。
【4】A考查上下文串联。根据前一句“Any fishy or strong smell means the fish isn’t fresh.”可知,带有强烈的味道的鱼都不是新鲜的,不应该买这样的鱼,A项与后句联系紧密,故选A。
【5】B考查上下文串联。根据“Put the whole fish on a plate and steam it in a steam pot”可知,本段介绍的是蒸鱼的方法,故选B。
【题目】【环境保护】根据资料,回答下列问题。
丹江口水库是南水北调中线工程的水源地。水源地丹江口水库库区周边地形以山地丘陵为主,特别是丹江口水库环库区丘陵垄岗区,地形破碎,岗岭起伏,十分复杂,土层较薄。种植业占农业总产值的53.4%。农业生产采用传统的粗放耕作方式,结构单一。下表为丹江口水库水源地土地利用类型的面积比例表。
土地利用类型 | 林地 | 草地 | 耕地 | 裸地 | 城镇 | 水域 |
面积比例(%) | 79.53 | 2.52 | 13.53 | 3.14 | 0.44 | 1.00 |
(1)试分析丹江口库区水质污染的主要原因。
(2)为了保证优质的水源供应北方地区,水源地在今后的农业开发中应该注意哪些问题?
(3)分析可能对丹江口水源区水质产生负面影响的土地利用类型,并指出从丹江口水库调水对下游的汉江河段水质带来的不利影响。
