                                                。

 ⑶ 冷却至室温后,甲同学又从分液漏斗中继续加入98%的浓硫酸10mL,发现几乎没有现象,再加热至沸腾,观察到有明显的现象,由此得出的结论是:

                                                    

 ⑷ 乙同学仍用上述装置直接从分液漏斗中加入98%浓硫酸10mL与铜片混合加热至沸腾,发现反应很剧烈,且试管底部有白色固体析出,生成该白色固体的化学反应方程式为:                                             。

The nurse was happy to make the switch, and after 51 he was comfortable, she left him alone. Slowly and painfully, he sat up to take his 52 look at the world outside. Finally, he would have the 53 of seeing it for himself. He strained (紧张地) to slowly turn to 54 the window beside the bed. It faced a blank wall.

第三节:阅读理解(共10小题;每小题2分,满分20分)

A

Much has happened since July 3, 1608, when French explorer Samuel de Champlain established a settlement in a place called Kébec ― an Algonquin word meaning where the River narrows. He might not have realized at the time that this day marked the beginning of a permanent French presence in North America, after several unsuccessful attempts.

For people of French descent (血统), all over America, everything points back to Quebec City, recognized as the founding site of French civilization in North America. At one point, Quebec City was at the centre of an empire, New France, which covered all of Eastern Canada and almost half of the current US territory. French possessions (领地) in North America then reached from the Gulf of St Lawrence to the Great Lakes and from Hudson Bay to the Gulf of Mexico.

After having been the capital of France’s colonies in America, and then of Lower Canada, Quebec City became the capital of the province of Quebec in 1867, when the Canadian Confederation came into being. Quebec City has kept growing and prospering continuously until today. And this is why it remains known as the founding site of French North America.

However, this does not mean that Quebec City is a museum town, focused only on its heritage (遗产) and history. On the contrary, it is a modern, people-friendly city that is resolutely turned towards the future.

56. Which of the following statements is TRUE?

       A. The empire of New France once controlled almost all of the America.

B. Quebec City is not only a museum town, but also the capital of France’s colonies.

C. July 3, 2008 will mark the 400th anniversary of the founding of Quebec City.

D. Samuel de Champlain established the empire of New France.

57. From this passage, we can infer that Quebec City ________.

       A. was, is and will be an important and growing city

B. is the biggest French enclave (飞地) in Canada

C. belonged to France before the Canadian Confederation came into being

D. is located in the centre of Canada

58. The main purpose of the passage is to ________.

       A. show us that in history Quebec City was once an important city

B. show us how Quebec City was established

C. tell us that Quebec City is a modern, people-friendly city

D. tell us a brief introduction of Quebec City

B

School is a place that is familiar to everyone. Let’s find out what American students do in school.   

An official dance party is held about twice a year in high schools in the United States. When the final football game is over for the season there is a homecoming party. Sometimes, students select a king from among the football players, and a queen from among the girls. Every student can attend and have fun with the help of their teachers. Sometimes, students, called bookworms, to the surprise of the other students, come to the party in a beautiful dress.
    The most exciting party that students can go to would have to be a dance party. Students attend it in dresses similar to those of Hollywood stars and the atmosphere is comparable to an Oscar Award party. Since such a party is for seniors, students usually stay up the night trying to enjoy their last year in high school.
    In American schools, instead of the teachers going to different rooms, students have their own class schedules (课程表) and go to different classrooms. When a student is away from school, they must have an explanation for being away along with the signature(签名) of a parent. The signed paper is then handed in to the school office. High school drop outs and students being expelled (除名) are not that uncommon in the States. High absences without excuses are one of the reasons why students are expelled from school. American students also enjoy a number of activities out of school like cheerleading (拉拉队), student government and a host of different sports.

59. Whose presence at the homecoming party can make others amazed?

   A. The king and the queen acted by students.      B. The laziest student in study.

   C. The teacher who offers advice.                      D. Students who study hardest.

60. Why do students hold the dance party till the next morning?

   A. Because they would like to dance and sang madly.

   B. Because this is the only chance that they get dressed like film stars. 

   C. Because students make it as exciting as an awarding party of Oscar.

   D. Because this perhaps is the last chance that they can enjoy their school life.

61. According to the passage, American students in school ________.

  A. study in the same classroom                            B. have the same class with each other

  C. attend different classes in different places                D. wait for their teachers in their class

62. What is this passage mainly about?

  A. The organizing of dance parties.                   B. Homecoming party. 

C. How to ask for a leave.                                  D. School life in America.

C

       Vancouver is located in the southwest corner of Canada in the province of British Columbia. Vancouver is the largest city in the province and the third largest in Canada. It covers an area of 113 sq km. It is surrounded by water on three sides and overlooked by the Coast Range. Its climate is one of the mildest in Canada. Temperatures average 3°C in January and 18°C in July. Vancouver's most rainfall occurs in winter.

       Archaeological evidence shows that coastal Indians had settled the Vancouver area by 500 BC. British naval (海军的) captain George Vancouver explored the area in 1792. Vancouver was founded as a sawmill settlement called Granville in the 1870s. The city was united in 1886 and renamed after Captain Vancouver.

       As the main western terminus of Canada's transcontinental highway and rail routes, Vancouver is the primary city of western Canada, as well as one of the nation's largest industrial centres.

       The Port of Vancouver is Canada’s largest and most various port, trading more than $43 billion in goods with more than 90 trading economies annually. Port activities generate 69,200 jobs in total with $4 billion in gross domestic product (GDP) and $8.9 billion in economic output.

       Vancouver is a major tourist place. In addition to the city's scenic location, visitors enjoy beautiful gardens and world-famous Stanley Park, one of more than 180 city parks, and a combination of natural forest and parklands near the city centre.

63. Which of the following description about Vancouver is NOT true, according to the passage?

       A. Vancouver is the third largest city in Canada.

       B. Vancouver is a city located on water.

       C. Vancouver is not far from the Coast Range.

       D. The largest industrial centre in Canada lies in Vancouver.

64. According to the passage, originally Vancouver is the name of ________.

       A. a British man who explored the city落千丈    B. a sawmill settlement called Granville      

C. the leader who controlled the area        D. a transcontinental highway

65. The passage mainly tells us ________.

       A. the Port of Vancouver, the largest one in Canada           B. how Vancouver got its name

       C. Vancouver’s history                       D. a brief introduction of the city of Vancouver
