Have you ever been to the beautiful country of Holland and its capital Amsterdam? Anyone who has traveled to Amsterdam would probably agree on one thing: Amsterdam’s story is a tale of two cities -- one during the day and a completely different one at night.

During the day, the largest city in the Netherlands sits quietly on the Amstel River.You can rent a bicycle, visit the Van Gogh or Anne Frank museum, or take a water taxi.But when the sun goes down, the partying begins.In the big clubs and in coffee shops, tourists gather to hang out, talk politics and smoke.

Several areas of the city clearly show the two worlds that rule Amsterdam.And they’re all within a short cab ride of each other.For example, Dam Square attracts daytime sightseers to its festivals, open markets, concerts and other events.Several beautiful and very popular hotels can be found there.And there’s the Royal Palace and the Magna Plaza shopping mall.

But at night party-seekers come to the square.Hip hop or funk music is heard there..So if you come, be ready to dance.The clubs don’t shut down until 4 am.

And while you’re there, check out the various inexpensive ways to tour the city.Don’t worry about getting lost.Although Dutch is the official language, most people in Amsterdam speak English and are happy to help you with directions.And you’ll notice that half the people in the streets are on bicycles they rent.

Amsterdam also has a well-planned canal system.For about 10 dollars, you can use the canal bus or a water taxi to cruise(巡游) the "Venice of the North".

The city has a historic past.One impressive place to visit is the Anne Frank House on Nine Streets.It was there that the young Jewish girl wrote her famous diary during World War II.Visitors can view Anne’s original diary and climb behind the bookcase to the room where she and her family hid from the Nazis for two years.

A.The experience of a beautiful girl survivor.

B.The glorious past of Amsterdam.

C.The life of Jewish during World War Ⅱ.

D.The suffering of the Dutch in wars.小题4:The passage is intended to  ____________        .

A.call up people’s memories of World War Ⅱ

B.tell readers what A Tale of Two Cities is about

C.instruct visitors what to do and see in Holland

D.offer readers some information about Amsterdam

新闻资料:我国于2007年10月24日“嫦娥一号”的成功发射是我国迈出地球的第一步,是中国航天事业发展的又一重大里程碑.月球作为地球的卫星被专家视为地球的“后院”和“第八大洲”,有着可以为人类利用的丰富资源.现有科学探索发现,月球上蕴藏着丰富的钛、铁、铀、钍、稀土、镁、磷、硅、钠、钾、镍、铬、锰等矿产,其中钛铁矿(FeTiOx),不仅是生产金属铁、钛的原料,这所含的氧还是未来月球基地生活用水和生产用水的重要来源.月球的土壤和岩石中蕴藏着丰富的“氦-3”燃料,“氦-3”是一种高效、清洁、安全、廉价的核聚变发电燃料.在地球矿产资源面临耗尽、石油枯竭迟早到来的情况下,载人航天登上月球,可以使之成为人类探测宇宙的前哨,对解决人类持续发展即将面临的难题具有重大意义.

根据以上信息回答下列问题:

(1)月球上蕴藏着丰富的钛、铁、铀、钍、稀土、镁、磷、硅、钠、钾、镍、铬、锰等矿产,这里的钛、铁、铀、……,指的是          (选填“单质”“元素”“原子”).

(2)月岩中钛铁矿主要成分的化学式为FeTiOx,其中铁元素和钛元素的化合价均显+3价.则x为              .

(3)发射“嫦娥一号”的长三甲火箭燃料是偏二甲肼(X),氧化剂是四氧化二氮(N2O4),燃烧的化学方程式为:X+2N2O4=3N2+2CO2+4H2O,X的化学式为             .

(4)“嫦娥一号”所用的燃料是液态氢,助燃剂是液态氧,燃烧时产生巨大和推动力将“嫦娥”送上了太空.

①写出氢气燃烧的反应化学方程式                                    

②液态氢作燃料除了燃烧时产生较大的推动力外,另一个优点是               .

(5)月球岩层中含有较丰富的镁资源.请用化学方程式解释下列设想:

利用镁能在二氧化碳中燃烧生成氧化镁和碳,同时放出大量热,以解决人类在月球上生存的燃料问题:                                         .
