【题目】山东居民自古有“闯关东”的说法,即不少山东老乡出山海关到东北发展;上世纪末,不少“东北客”又返回山东定居,导致了人口的“雁南飞”现象。回答下列问题。
【1】材料所述现象属于
A.国际人口迁移 B.民工流动
C.国内人口迁移 D.人口流动
【2】上述现象的出现,其主要原因是
A.国家政策的引导 B.经济原因
C.气候变化 D.资源开发
【答案】
【1】C
【2】B
【解析】
试题分析:
【1】山东居民“闯关东”该人口空间位移发生在国内,不属于国际人口迁移,A错。定居地发生了永久性或者长期改变,属于人口迁移现象,所以材料所述属于国内人口迁移,故选C。
【2】山东居民“闯关东”是指在自然灾害发生的年份,山东饥民自发的到土地、森林等资源比较丰富,人口相对较少的东北地区去发展,以度过饥荒,有些随之定居东北。“东北客”为我国开发东北起到了重要作用。改革开放以后,山东省因为沿海的区位优势,经济发展迅速,而东北地区因为沉重的经济负担,加之国家政策的一些原因,发展速度相对较慢,就业机会减少,所以有些老“东北客”返乡工作、定居。显然,这其中经济因素是主要的。

【题目】阅读理解。
If you are a fruit grower—or would like to become one—take advantage of Apple Day to see what’s around.
It’s called Apple Day but in practice it’s more like Apple Month. The day itself is on October 21, but sinceit has
caught on, events now spread out over most of October around Britain.
Visiting an apple event is a good chance to see, and often taste, a wide variety of apples. To people who are used to the limited choice of apples such as Golden Delicious and Royal Gala in supermarkets, it can be quite an eye opener to see the range of classical apples still in existence, such as Decio which was grown by the Romans. Although it doesn’t taste of anything special, it’s still worth a try, as is the knobbly(多疙瘩的) Cat’s Head which is more of a curiosity than anything else.
There are also varieties developed to suit specific local conditions. One of the very best varieties for eating quality is Orleans Reinette, but you’ll need a warm, sheltered place with perfect soil to grow it, so it’s a pipe dream for most apple lovers who fall for it.
At the events, you can meet expert growers and discuss which ones will best suit your conditions, and because these are family affairs, children are well catered for with apple-themed fun and games.
Apple Days are being held at all sorts of places with an interest in fruit, including stately gardens and commercial orchards(果园).If you want to have a real orchard experience, try visiting the National Fruit Collection at Brogdale, near Faversham in Kent.
【1】What can people do at the apple events?
A. Attend experts’ lectures.
B. Visit fruit-loving families.
C. Plant fruit trees in an orchard.
D. Taste many kinds of apples.
【2】What can we learn about Decio?
A. It is a new variety.
B. It has a strange look.
C. It is rarely seen now.
D. It has a special taste.
【3】What does the underlined phrase “a pipe dream” in Paragraph 3mean?
A. A practical idea. B. A vain hope.
C. A brilliant plan. D. A selfish desire.
【4】What is the author’s purpose in writing the text?
A. To show how to grow apples.
B .To introduce an apple festival.
C. To help people select apples.
D. To promote apple research.

【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.
