在浩荡的黄河岸边，有一座独具魅力的历史文化名城——吴堡。

“邑枕黄河”的吴堡，是陕北通往华北的桥头堡。

在吴堡黄河古渡旁，矗立．．着吴堡的红色地标“毛主席东渡纪念碑”。

[甲]吴山之巅，有一座石城环山抱水，拔地通天：东以黄河为池，西以悬崖为堑，南为绝壁天险，北为咽喉狭道。

[乙]这就是“名闻天下的华夏第一石城”——古吴堡石城。

千余年来，吴堡虽饱经战争创伤，却始终“一夫当关，万夫莫开”，从未被破城。

这座无坚不摧．．．．的天堑雄堡，使吴堡成为享誉天下的“铜吴堡”。

[丙]古吴堡石城年代久远，据成书于唐代的《元和郡县志》记载：“刘裕子刘义真于长安，遂虏其部，筑城以居之，号曰吴儿城。

时间本身总是少言寡语，无论．．你是善待它，或冷落它，甚至戏弄它，它既不愤怒，也无责怪，从来不吭一声。

[乙]徐特立说：“鲁迅认为妨碍别人工作时间是谋财害命，我也以为浪费自己的时间就是自杀，尤其是浪费休息的时间，直接威胁着生命。

”现今人类司空见惯．．．．了浪费时间的现象，不仅有的人优哉游哉，把自己的时间看成不值一文．．．．的流水，更有大量的社会活动与拖拉式的服务，平白无故地掠夺人们的宝贵时光，让你无可奈何。

[甲]树，不仅实用，还意味着福佑、恩泽和繁衍；不仅赐人花果和木质，还传递亲情和美德，承载光阴与家世。

树非速生，它耐受、持久，春华秋实，像一位高寿的家族长者，俯瞰儿孙绕膝。

所谓“荫庇”“荫佑”之说，皆缘于树。

再穷的人家，也能给后人撑起一大片树荫。

这是祖辈赠与子嗣最俭朴．．最牢固的遗产了。

[乙]树是一轮轮人生的见证者，见证了他们从跌撞的蒙童、攀爬的顽少，变成拄杖的耄耋老者——闹饥荒时，树先枯，人后亡，因为果腹的最后一样东西，是树皮。

几千年来，凡户居，必在一棵大树下；凡村头，必有一棵神．采奕奕．．．的老树。

树，是家舍的象征，是地址的招魂幡。

[丙]离家者，最后一眼回望的是它；返乡者，远远眺见的也是它。

如今的家业里，少了树。

“家”失去了树荫的覆护，光秃秃曝于烈日下。

树，在马路上流浪。

我们只是乘车迅速地掠过．．它们。

它们身上，没有我们的指纹和体温。

人和树，亲情已断，形同陌路．．．．。

迄今为止，我仅见过一次黄河。

那是个晴朗的秋日，风和日丽，黄河缓缓地流淌着。

[甲]水面宽阔、波澜不惊．．．．；平坦的河中央有一抹沙渚，虽缺少萋萋芳草，却足够长脚鹭鸶短脚水鸟悠闲．．地在上面散步休憩。

置身河边，隔着宽阔的水面，隐约可见对岸散落的村庄与稀疏的树林，遥遥如海市蜃楼．．．．一般。

[乙]那一瞬间，我甚至产生错觉，以为自己到了海边。

In Europe for example, coffee shops are common places for people to meet friends while they drink coffee. On the other hand, places like this were not as common in North America in the past. Instead, people in North America liked to drink coffee in their homes with friends. The coffee culture in the USA changed, when Starbucks (星巴克) coffee shops spread throughout the country.The first Starbucks coffee shop opened in 1971 in downtown Seattle, Washington，in the USA. It was a small coffee shop that cooked its own coffee beans. The coffee shop's business did well, and by 1981 there were three Starbucks stores in Seattle.Things really began to change for the company in 1981. That year, Howard Schultz met the three men who ran Starbucks. Schultz worked in New York for a company that made kitchen equipment (设备) . He noticed that Starbucks ordered a large number of special coffee makers, which caused his great interest. Schultz went to Seattle to see what Starbucks did. In 1982, the original Starbucks owners hired Schultz as the company's head of marketing (市场营销).In 1983, Schultz traveled to Italy. The special environment of the espresso (浓咖啡) bars there caught his eyes. Back in the USA, Schultz created an environment for Starbucks coffee shops that was comfortable and casual, and customers everywhere seemed to like it. Starbucks began opening more stores in the USA. Then the company opened coffee shops in other countries as well. Today, there are more than 16,000 Starbucks coffee shops all over the world.However，that does not mean Starbucks has not had problems. In fact, many Starbucks stores have closed over the past few years. On the one hand, this is because there were too many coffee shops competing (竞争) for business in one small area. On the other hand, stores in some countries closed because the coffee culture there did not match with the comfortable environment offered by Starbucks.( ) 1. The underlined word "ran" in Paragraph 3 probably means ____.A. closedB. managedC. madeD. sold( ) 2. According to the passage, which is the right order for the following sentences?a. This man helped to make Starbucks a huge coffee company.b. Starbucks began as a small coffee company in Seattle in the USA.c. He went to Seattle to learn about the company and later worked for it.d. Howard Schultz found Starbucks ordered lots of special coffee makers.A. a﹣b﹣d﹣cB. c﹣a﹣b﹣dC. b﹣d﹣c﹣aD. d﹣c﹣a﹣b( ) 3. Why did so many Starbucks close in small areas？A. Because the coffee in these places was too expensive.B. Because the style of the coffee stores seems the same.C. Because people like to drink coffee at home with friends.D. Because there were too many coffee shops in one place.( ) 4. To tell us the story of Starbucks, the writer did the following except ____.A. introducing how Starbucks became successfulB. showing what Schultz did to help Starbucks become successfulC. telling what difficulties Starbucks facesD. telling what Starbucks did to deal with his problems( ) 5. What's the best title for the passage？A. The History of StarbucksB. The Culture of StarbucksC. The Popularity of StarbucksD. The environment of StarbucksEvery year movie festivals around the world present awards for the best director. Some of this festival began ten years ago, and their list of winners for the best director is quite long. However, among all the names of winners, it's not easy to find the names of female directors. The Cannes Film festival is the first major movie festival to name female director as the best director of the year in 1961. A Russian director called Yuliya Solnsteva won at Cannes. Since then, some movies directed by female directors have won the the Best Picture. But no female directors have won the Best Director at Cannes.The Best Director award at the Berlin International Film Festival is called the Silver Bear award. Only one woman has succeeded in winning it so far. She was Astrid Henning-Jensen from Denmark. Over her career, she directed more than 20 movies and in 1979, she won the Silver Bear for her movie Winterborn.It is the most difficult for female directors to win the Best Director in the Oscars in the USA. In fact, since the Oscars began in 1929, only four women have ever been nominated for the Best Director. The first woman to actually win this award was Kathryn Bigelow for directing The Hurt Locker. She received the award in 2010.Over the years, women have directed many wonderful movies. People like them even though they don't win awards. And they make nice films. For example, Nora Ephron directed the great romantic-comedy Sleepless in Seattle and Vicky Jenson directed a wonderful animated movie Shrek.1.__________2. __________3. __________4.__________5.__________2017学而思网校小学英语辅导老师功底测试B卷ANSWERI Multiple Choice 1-5 DBDAC 6-10 BDDDD 11-15 AAACC 16-20CCADAII Cloze 1-5 ACBAD 6-10 CDACBIII ReadingA 1-5 BBACDB 1--5 BCCDDC 1-5 BCDDAD 1-5 （1）awards（2）Russia（3）only（4）given（5）examplesI Multiple Choice (1'x20=20')1.【答案】D【解析】考查名词的所有格。
