III. Reading Comprehension
Section A
Directions: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.
When we read books we seem to enter a new world. This new world can be similar to the one we are living in, or it can be very __44__. Some stories are told as if they were true. Real people who live in a __45__ world do real things; in other words, the stories are about people just like us doing what we do. Other stories, such as the Harry Potter books, are not __46__. They are characters and creatures that are very different from us and do things that would be impossible for us.
But there is more to books and writing than this. If we think about it, even realistic writing is only __47__. How can we tell the difference between what is real and what is not real? For example, when we read about Harry Potter, we do seem to learn something
about the real world. And when Harry studies magic at Hogwarts, he also learns more about his real life than __48__. Reading, like writing, is an action. It is a way of thinking. When we read or write something, we do much more than simple look at words on a page. We use our __49__, which is real, and our imagination, which is real in a different way, to make the words come to life in our minds.
Both realism and fantasy(幻想) use the imagination and the ―magic‖ of reading and writing to make us think. When we read something realistic, we have to __50__ that the people we are reading about are just like us, even though we __51__ that we are real and they are not. It sounds __52__, but it works. When we read, we fill in missing information and __53__ the causes and effects of what a character does. We help the writer by __54__ that what we read is like real life. __55__, we are writing the book, too.
Most of us probably don‘t think about what is going on in our __56__ when we are reading. We pick up a book and lose ourselves in a good story, eager to find out what will __57__ next. Knowing how we feel when we read can help us become better __58__, and it will help us discover more about the real magic of books.

(A)
George Gershwin, born in 1998, was one of America‘s greatest composers. He published his first song when he was eighteen years old. During the next twenty years he wrote more than five hundred songs.
Many of Gershwin‘s songs were first written for musical plays performed in theatres in New York City. These plays were a popular form of entertainment in the
1920s and 1930s. Many of his songs have remained popular as ever. Over the years they have been sung and played in every possible way — from jazz to country.
In the 1920s there was a debate in the United States about jazz music. Could jazz, some people asked, be considered serious music? In 1924 jazz musician and orchestra leader Paul Whiteman decided to organize a special concert to show that jazz was serious music. Gershwin agreed to compose something for the concert before he realized he had just a few weeks to do it. And in that short time, he composed a piece for piano and orchestra which he called Rhapsody in Blue. Gershwin himself played the piano at the concert. The audience were thrilled when they heard his music. It made him world-famous and showed that jazz music could be both serious and popular.
In 1928, Gershwin went to Paris. He applied to study composition (作曲)with the well-known musician Nadia Boulanger, but she rejected him. She was afraid that classical study would ruin his jazz-influenced style. While there, Gershwin wrote An American in Paris. When it was first performed, critics (评论家)were divided over the music. Some called it happy and full of life, to others it was silly and boring. But it quickly became popular in Europe and the United States. It still remains one of his most famous works.
George Gershwin died in 1937, just days after doctors learned he had brain cancer. He was only thirty-nine years old. Newspapers all over the world reported his death on their front pages. People mourned the loss of the man and all the music he might have still written.
59. Many of Gershwin‘s musical works were ________ .
A. written about New Yorkers
B. Composed for Paul Whiteman
C. played mainly in the countryside
D. performed in various ways
60. What do we know about the concert organized by Whiteman?
A. It attracted more people to theatres
B. It proved jazz could be serious music
C. It made Gershwin leader of the orchestra
D. It caused a debate among jazz musicians.
61. What did Gershwin do during his stay in Paris?
A. He created one of his best works
B. He studied with Nadia Boulanger
C. He argued with French critics
D. He changed his music style
62. Which of the following best describes Gershwin?
A. Talented and productive
B. Serious and boring
C. popular and unhappy
D. Friendly and honest
(B)
Planning a visit to the UK? Here we help with ways to cut your costs.
A VOID BIG EVENTS Big sporting events, concerts and exhibitions can increase the cost of accommodation and make it harder to find a room. A standard double room at the Thistle Brighton on the final Friday of the Brighton Comedy Festival (19 Oct.) cost ￡169.15 at https://www.wendangku.net/doc/4a5304916.html,. A week later, the same room cost ￡118.15.
If you can be flexible and want to know dates to avoid—or you‘re looking for a big event to pass your time—check out sites such as https://www.wendangku.net/doc/4a5304916.html,, which allow you to search for events in the UK by city, date and category.
STAYAWAY FROM THE STATION If traveling to your destination by train, you may want to find a good base close to the station, but you could end up paying more for the sake of convenience at the start of your holiday.
Don‘t be too choosy about the part of town you stay in. Booking two months in advance, the cheapest room at Travelodge‘s Central Euston hotel in London for Saturday 22 September was ￡95.95. A room just a tube journey away at its Covent Garden hotel was ￡75.75. And at Farringdon, a double room cost just ￡62.95.
LOOK AFTER YOURSELF Really central hotels in cities such as London, Edinburgh and Cardiff can cost a fortune, especially at weekends and during big events. As an alternative consider checking into a self-catering flat with its own kitchen. Often these flats are hidden away on the top floors of buildings. A great example is the historic O‘Neill Flat on Edinburgh‘s Royal Mile, available for ￡420 for five days in late September, with room for four adults.
GET ON A BIKE London‘s ?Boris bikes‘ have attracted the most attention, but other cities also have similar programmes that let you rent a bicycle and explore at your own pace, saving you on public transport or car parking costs.
Among the smaller cities with their own programmes are Newcastle (casual members pay around ￡1.50 for two hours) and Cardiff (free for up to 30 minutes, or ￡5 per day).
63. The Brighton Comedy Festival is mentioned mainly to show big events may
__________.
A. help travelers pass time
B. attract lots of travelers to the UK
C. allow travelers to make flexible plans
D. cause travelers to pay more for accommodation
64. ―Farringdon‖ in Paragraph 5 is most probably __________.
A. a hotel away from the train station
B. the tube line to Covent Garden
C. an ideal holiday destination
D. the name of a travel agency
65. The passage shows that the O‘Neill Flat __________.
A. lies on the ground floor
B. is located in central London
C. provides cooking facilities for tourists
D. costs over ￡100 on average per day in late September
66. Cardiff‘s program allows a free bike for a maximum period of __________.
A. half an hour
B. one hour
C. one hour and a half
D. two hours

必修三 数学测试题
必修三 数学测试题 一、选择题(本大题共12个小题，每小题5分，共60分，在每小题给出的四个选项中只有一个是符合题目要求的) 1．在频率分布直方图中，各个长方形的面积表示( ) A ．落在相应各组的数据的频数 B ．相应各组的频率 C ．该样本所分成的组数 D ．该样本的样本容量 [答案] B [解析]在频率分布直方图中，横轴是组距，纵轴是频率组距 ，故各个长方形的面积＝组距 ×频率组距 ＝频率． 2．下边程序执行后输出的结果是( ) n ＝5S ＝0 WHILE S <15S ＝S ＋n n ＝n －1WEND PRINT n END A ．－1 B ．0 C ．1 D ．2 [答案] B [解析]S ＝5＋4＋3＋2＋1；此时n ＝0. 3．用秦九韶算法计算多项式f(x)＝x 6－12x 5＋60x 4－160x 3＋240x 2－192x ＋64，当x ＝2时的值为( ) A ．0 B ．2 C ．－2 D ．4 [答案] A [解析]先将多项式f(x)进行改写： f(x)＝x 6－15x 5＋60x 4－160x 3＋240x 2－192x ＋64＝(((((x －12)x ＋60)x －160)x ＋240)x －192)·x ＋64.
然后由内向外计算得 v 0＝1，v 1＝v 0x ＋a 5＝1×2－12＝－10， v 2＝v 1x ＋a 4＝－10×2＋60＝40， v 3＝v 2x ＋a 3＝40×2－160＝－80， v 4＝v 3x ＋a 2＝－80×2＋240＝80， v 5＝v 4x ＋a 1＝80×2－192＝－32， v 6＝v 5x ＋a 0＝－32×2＋64＝0. 所以多项式f(x)当x ＝2时的值为f(2)＝0. 4．一班有学员54人，二班有学员42人，现在要用分层抽样的方法从两个班中抽出一部分人参加4×4方队进行军训表演，则一班和二班分别被抽取的人数是( ) A ．9人、7人 B ．15人、1人 C ．8人、8人 D ．12人、4人 [答案] A [解析]一班抽取人数54×1696＝9(人)，二班抽取人数42×16 96 ＝7(人)． 5．观察新生婴儿的体重，其频率分布直方图如图所示，则新生婴儿体重在(2 700,3 000)范围内的频率为( ) A ．0.001 B ．0.1 C ．0.2 D ．0.3 [答案] D [解析]频率＝0.001×300＝0.3. 6．期中考试以后，班长算出全班40个人数学成绩的平均分为M ，如果把M 当成一个同学的分数，与原来的40个分数一起，算出这41个分数的平均值为N ，那么M N 为( ) A .40 41 B ．1 C .4140 D ．2
高二下学期期末考试英语试题
高二下学期期末考试英语试题 第二部分：阅读理解（共两节，满分40分） 第一节（共15小题；每小题2分，满分30分） 阅读下列短文，从每题所给的四个选项（A、B、C、D）中，选出最佳选项。 A Hotel rooms come in a variety of styles and price ranges. Despite differences m decoration and price, one thing most hotels have in common is a set of rules. Failure to obey these rules can result in fees or fines to cover hotel room damages, removal from the hotel or possibly even arrest. Smoking Some hotels are completely non-smoking. Some hotels designate smoking and non-smoking rooms. If you smoke in a non-smoking room, you will likely be fined hundreds of dollars and possibly asked to leave. Number of Guests Most regular hotel rooms are designed for two adults. If you have more than two people staying in the room, the hotel will likely charge an additional fee for each extra guest, though some hotels let children stay free. Do not put more than four adults in the room unless the hotels policy permits that many people. Or you might be fined or removed from the hotel Hotel Reservations Requirements Most hotels require a major credit card to reserve the room. You can pay cash at the end of your stay, but do not be surprised if there is a temporary charge on your card for a few days after your stay. Most hotels authorize a security deposit on your card to cover any possible damages to the room. Once the hotel confirms that the room is undamaged and that you do not break any hotel policies, your security deposit will be refunded. Breaking the Law You cannot break the law in your hotel room, just as you cannot break the law in your own home or in public. Do not do drugs or commit any other criminal act in the hotel room. If you do, you will likely be arrested. Noise Most hotels have a noise policy you must obey. If you are being too loud you will usually get a warning. If the noise continues and more complaints are issued, you will likely be kicked out of the hotel, regardless of what time it is. 21. What is the main purpose of this passage?
