第一定律(惯性定律)指出,一个物体会保持静止或匀速直线运动,直到外力迫使它改变状态。
第二定律(加速度定律)指出,物体的加速度与作用在其上的净外力成正比,与物体的质量成反比,且加速度的方向与净外力的方向相同。
第三定律(作用与反作用定律)指出,对于每一个作用力,总有一个大小相等、方向相反的反作用力。

(217) 367-1544[B]Some of Vincent van Gogh's most famous works are his sunflower series. He painted a total of twelve of these canvases (油画), although the most commonly referred to are the seven he painted while in Arles in 1888~1889. He had painted the other five while in Paris in 1887.While Vincent himself never actually stated why he liked the sunflowers in particular, references to them are made in his many letters, which help give us some ideas. In a letter to his sister dated 21 August 1888, he talked of his friend Gauguin coming to live with him in Arles. Then he went on to say that he would like to decorate the whole studio with nothing but sunflowers.Vincent had quite an attachment to the flowers personally.In the year before his death he wrote to his brother,“It is a kind of painting that rather changes in character,and takes on a richness the longer you look at it...You know the peony (牡丹) is Jeannin's, the hollyhock (蜀葵) belongs to Quost, but the sunflower is somewhat my own.” In many of his letters he spoke glowingly (热心地) of the richness of color that he saw in the sunflowers, and his desire to paint them quickly before they faded.But whether Vincent painted the sunflowers because he was trying to please Gauguin, or because he really loved the sunflowers for themselves as they brought his joy in color, he certainly left us works of art to enjoy.24.________showed that Vincent liked the sunflowers best.A.His many letters B.12 canvasesC.The hollyhock D.The peony25.The best title of this passage would probably be________.A.Vincent van Gogh's Famous WorksB.Vincent van Gogh Really Loved SunflowersC.Vincent van Gogh Was Kind to His FriendD.Vincent van Gogh's Really Interesting Life26.According to Vincent van Gogh's letters we can know that________.A.Gauguin was Vincent van Gogh's close friendB.Vincent would like to live with Gauguin all the timeC.Vincent's studio was full of sunflowers every dayD.Gauguin was clearly interested in sunflowers27.We can know from the third paragraph that________.A.some sunflowers belong to Vincent van GoghB.sunflowers are more beautiful than hollyhockC.Vincent liked the color of the sunflowers bestD.Vincent liked painting all kinds of flowers[C]In his book The Tipping Point Canadian author Malcolm Gladwell explains how a trend (潮流) can take many forms. It can be a general change in social behaviour, an idea or a fashion. However, why do some trends catch on and others not? What makes one particular brand of training shoe suddenly become the must-have product? How do people find out about trends and what makes people want to buy into them? Is it simply a question of keeping up with other people?In his new work, Gladwell explores the moment when something becomes common and how products, ideas, messages and forms of behaviour spread. He looks at the reasons why trends are similar in the way they develop to outbreaks of disease, or medical epidemics (流行病).Epidemics, like trends, start in a very small way, maybe from a single person with a virus, then spread very quickly until they take over the population and appear to be everywhere. Eventually, they will slow down gradually or die out suddenly. Gladwell shows how these changes happen not gradually but at one sudden moment.Gladwell identifies three types of people who are influential in the development of these kinds of social epidemics:Connectors are people in a community who have wide social circles. They know a lot of people and like to introduce people to each other. The people they know often come from a variety of social, cultural, professional and economic circles.Mavens are people with a lot of knowledge or experts in a particular field. They wish to pass on their knowledge to others. Mavens collect and gather information so are the first to pick up on new trends.Salesmen are people with charisma (魅力). They have a “soft” influence over people rather than actual power. This means they are influential because people want to imitate them.Overall, Gladwell's book is a thought-provoking (引人深思的) read for anyone interested in the origins of trends. What's more, he writes in a clear style so even the most difficult ideas are easy to understand.28. What does the underlined part “buy into” in Paragraph 1 mean?A. Pay money for.B.

This book is interesting but hard to understand for readers.[D]Every morning, the newspaper chief editor(主编) holds a meeting with the reporters. They discuss the main events(事件) of the day. Reporters are then sent to cover the events.As soon as the reporters know what to write about, they get down to work. They telephone people and fix a time for a face-to-face interview with them. Sometimes they do telephone interviews. Checking information is very important. They go to the newspaper’s own library to look up any information that they need. This is called “doing one’s homework”.At the same time, the picture editor decides which photographs will be used for the next day’s paper. All the people who work on a newspaper must be able to work fast. Reporters have to stop working on one story and start working at once on the important new one. They must find out the new information as quickly as possible. Later in the day, everything is put together at the news desk. Reporters return, type their stories into the computer and hand them to the editor.The chief editor decides which will be the most important story on the front page. Sometimes this will have to be changed if something more important happens late in the day. Other editors read the stories which the reporters have written and make any necessary changes.Finally, there is no more time left for adding new stories, and the time for printing(印刷) the newspaper has come. This is done on fast-moving printing machines. The newspapers are then delivered(发送) by truck, plane or rail. Speed is important. People want to buy the latest newspaper; nobody wants to buy yesterday’s.32.
