Wind is the great maker of waves. There are exceptions, such as the tidal waves, sometimes produces by earthquakes under the sea. But the waves most of us know are produced by winds blowing over the sea.Now before constructing an imaginary life history of a typical wave, we need to know certain physical things about it. A wave has height, from trough (low point)to crest (high point),and it has length—the distance from this crest to that of the following wave. The period of the wave means the time it takes for succeeding crests to pass a fixed point. None of these things stays the same— for all depend upon the depth of the water and many other matters.
The water that makes up a wave does not advance with it across the sea. Each drop of water turns around in a little circle with the passing of the wave, but returns very nearly to its original position. And it is fortunate that this is so, for if the huge masses of water that make up a wave actually moved across the sea, sailing would be impossible.
If we want to find the speed of a wave, we may use the following way:
Speeding="Wavelength×Frequency"
Here, wavelength is the distance between two high points (crests), frequency means the number of cycles per second.

D. The length of a wave means the distance between crest and trough.
43.The underlined word “succeeding” means__________.
A. reaching an aim B. doing well C. following after D. taking place
44.If the speed of wave 1 is 100 cm/s, and its frequency 10;and the frequency of wave 2 is 300,while its speed is twice that of wave 1.Which of the following is true?
A. The wave-lengths of the two are equal.
B. The wave-length of wave 1 is 10 times longer than that of Wave 2.
C. The wave-length of wave 2 is longer than that of wave 1.
D. The wave-length of wave 1 is longer than that of wave 2.
Last Sunday, Aron Ralston, an experienced hiker and mountaineer, set off to walk alone through the Bluejohn desert canyon (峡谷) in Utah. He was planning an eight-hour, 21–kilometer hike. While he was climbing through a narrow part of the canyon, a big stone weighing about 400 kilos fell and trapped his right arm.
When he failed to return to the mountain camp where he was staying that night, people simply thought he had decided to camp out somewhere in the canyon. When he still had not returned by Tuesday, the alarm was raised, A search party set out on Wednesday evening, but there we no sign and his family began to fear the worst.
In fact, Ralston, 27, was lying trapped in the canyon. By Tuesday, he had run out of water. By Thursday, he realized that he would not survive unless he took unusual action, so he used his pocket knife to cut his arm below the elbow (肘). He then climbed down to the bottom of the canyon. There he met two other hikers, who helped him back to safety. He received some help at a local hospital before being carried to St. Mary’s hospital in Grand Junction, Colorado for surgery.
Ralston’s astonishing survival brought equal amounts of praise and criticism. While praising the climber for his bravery and calm, experts also pointed out he had broken the first rule of outdoor pursuits. He had failed to leave words with anyone of where he was going that day.
This was in fact Ralston’s second near-death experience. In February, he was buried up to the neck in snow by an avalanche (雪崩) while skiing in the Colorado Rockies. Ralston not only managed to dig himself out but he also rescued his skiing companion, who had been completely buried in the snow. Ralton rescued himself and his friend in less than 15 minutes.According to the passage, a “hiker” is probably someone who _______.

Some of my friends are making big decisions in their life: Which universities should they apply to? I also notice that many high school students in China are thinking of studying at universities abroad. Unluckily, from what I’ve seen, the information given by some websites and other media about studying abroad is very limited and sometimes even wrong.
There was once a Chinese girl who hoped that she could go to Columbia University in the US because she wanted to major in journalism. However, they have no journalism program at the undergraduate level! What’s more, in both Canada and the US, it’s not suggested that students throw themselves into journalism right after high school. School say that students should take in more knowledge about the world and writing before entering that field.
The University of Waterloo, a Canadian university famous for its engineering program, is another example. The emphasis (重视)of engineering in this school may go beyond your expectations. According to our teachers, this university spent millions of dollars building a library just for engineering students. The school’s computer science, mathematics and accounting are also great programs for students.
But, to be honest, according to my friends who have visited this university, the campus and the food are not very nice. Maybe this is because the school stresses its academic( 学术)strengths too much, thereby paying little attention to personal comforts.
Now you see, choosing a university is really not that easy. We need to do good research and consult as many people as possible before making a decision.For high school students it’s very important to __________.
| A．choose a proper university |
| B．study at American universities |
| C．learn the information about websites |
| D．supply the information about studying abroad |
Who can major in journalism program in Columbia University?
| A．Chinese girls. | B．Graduates. |
| C．Undergraduates. | D．High school students. |
From Paragraphs 3 and 4 we can learn in the University of Waterloo _______.
| A．engineering program is as famous as computer science |
| B．engineering students are the most intelligent |
| C．the campus is very small and dirty |
| D．the library for engineering students is very good |
What’s the best title for the passage?
| A．Choosing a university is not easy. |
| B．How to study at universities abroad. |
| C．A Chinese girl and Columbia University. |
| D．Academic strengths of the University of Waterloo. |
China’s new popular word, “tuhao”, may be taken in next year’s Oxford English dictionary. The word caught the attention of the dictionary’s editing team after BBC’s recent program on influential Chinese words.
“If its influence continues, it is very likely to appear on our updated list of words,” said Julie Kleeman, project manager with the editing team. Kleeman told the Beijing Youth Daily that “tuhao” has some similarities with the English word “bling”, which refers to expensive, ostentatious (阔绰的) clothing or jewelry. Both the two words have existed for long but later on took a new meaning.
In Chinese, “tu” means rude and “hao” means rich. It has traditionally been referred to rich people who throw their weight around in China’s rural areas. In recent years, people in the ACG (anime, comic and game) circle borrowed the term to describe those who spend money in an unreasonable manner.
The word gained acceptance in September with the launch (投放) of Apple’s new gold-colored iPhone, an item loved by China’s nouveau riche (暴发户). The color became known as “tuhao gold”.The word is now often used by the online community to refer to people who have the cash but lack the class to go with it.
Kleeman also mentioned another Chinese word “dama” which may also be taken in the dictionary.
“Dama”, meaning middle-aged women, was first used in the Western media by the Wall Street Journal in May when thousands of Chinese women were buying up record number of gold. They were the driving force in the global gold market between April and June when the gold prices had dropped. “People can have an intuitive (直觉的)grasp of the meanings if they see pinyin”, Kleeman said adding that people avoided using an English word to keep the original meaning. The new words will be first uploaded on the official website before the dictionaries arrive. The online version is also renewed every three months.Why is the word “tuhao” likely to be taken in Oxford English Dictionary?
| A．Because it represents noble and rich |
| B．Because it has the same meaning with an English word. |
| C．Because its influence becomes bigger and bigger |
| D．Because it is popular in online game circle. |
What’s the similarity between “tuhhao” and “dama”?
| A．Both take new meanings. |
| B．Both were created in British. |
| C．Both will be uploaded in the next dictionary version. |
| D．They have the same meaning. |
What’s the main idea of the passage?
A, The popularity of the two words “tubao” and “dama”.
B. The possibility to be taken in Oxford English Dictionary for “tuhao” and “dama”.
C. The new meanings of the two words “tuhao” and “dama”
D. The influence of Chinese in modern world.The passage most probably belongs to _____________.

Career education is instruction intended to help young people identify, choose, and prepare for a career. Such instruction may focus on a person’s role in work, leisure, or family life. Career education differs from vocational education, which is designed to teach specific occupational skills.
Career education includes the formal and informal learning that occurs in the family, in the community, and in schools. In schools, career education consists of instructive activities included in many courses. These activities are designed to improve the attitudes, knowledge, and skills important for work roles. Career education helps students develop self- understanding and use it to plan their education and working life.
A complete career education program in school begins in kindergarten and continues at least through high school. Many colleges and universities also offer career education through their counseling(咨询) programs. In kindergartens and elementary schools, youngsters learn about different types of work. In middle schools or junior high school, children begin to explore the occupations and leisure activities that interest them most. In high school, students get more specific information about occupations and life styles. They may be in classroom, small group, or individual sessions where they learn how to make career decisions. They also should obtain the skills they need for further study or for a job after graduation. Counselors provide information on such matters as how to locate and apply for jobs and how to be successful in interviews. Teachers and counselors use a variety of methods to provide career education, including films about occupations or industries. Children may invite parents or other adults to come to school and describe their jobs. A student may accompany a worker on the job. Cooperative education combines classroom study with practical work experience.According to the passage, which statement is true?
| A．Career education is carried out in primary schools only. |
| B．Career education is carried out in middle schools only. |
| C．Career education is carried out in colleges only. |
| D．Career education is carried out in the whole process of people’s education—from kindergarten to university. |
It may be inferred from the passage that _________.
| A．not only teachers but also parents are responsible for youngsters’ career education |
| B．in high schools, students know more specific information about occupations |
| C．career education may be in classroom, small group, or individual sessions |
| D．teachers use a variety of methods to provide career education, including films |
A child may get career education in all the following places EXCEPT _________.
| A．schools | B．homes |
| C．communities | D．public places |
