| Choosing the right university for you is a big decision with many factors to consider. The institution that you choose will not only be the one that ensures your academic goals, but it will also be where you will live, learn, play sports, socialize and work for several years. Therefore, before you start filling out those university application forms, take a step back and consider the many variables that affect the "fit" of a university to your unique personality and educational goals. Take a look at the following factors, and decide which ones mean the most to you. Consider your educational goals. You will discover that different schools are more recognized or progressive in your chosen field of study than others. For this reason, talk to advisors, professionals in your field, or go to clubs organized by the alumni(校友). When you check out school ranking for your major, you may find that your first choice is not really a match, while another fits perfectly. Consider costs. It will be no surprise to you at this point that not all schools cost the same. Some of the more famous schools are so because they are difficult to get into and difficult to pay for. Don"t let this necessarily stop you. Just keep this consideration in mind as you narrow your list of potential schools. Choosing a university should not be done only on reputation, but also take the academic programs and overall environment into consideration. Be aware that reputations are sometimes out of date or overstated, so first-hand experience is often beneficial. Once you"ve identified the factors that are most important to you, you"ve taken the first steps towards making a successful choice. Make sure you pick a university that will serve your needs throughout your university career. 1. The passage is written for . A. college students B. high school students C. people out of jobs D. people looking for jobs 2. In the Paragraph 4, the writer advises you not to stress on . A. overall environment B. the academic programs C. first-hand experience D. a university"s reputation 3. It"s better to choose a university which . A. costs you a little B. is well equipped C. is well known D. meets your needs 4. What does the passage mainly talk about? A. Qualities of a good university. B. Ways to achieve your goals. C. Advice on choosing a university. D. Factors influencing your choice. | |||

| British scientists may have discovered the reason why red wine appears to protect the heart. They say natural chemicals found in red wine appear to protect against blocked blood vessels(血管). The chemical substances are called poly-phenols(多酚). They come from the outer covering of grapes. They are not present in other alcoholic drinks. Researchers say their discovery explains why many people in southern Europe can eat fatty foods and still have a low risk of heart disease. People in France, for example, have lower rates of heart disease than Americans do. Yet the traditional French diet includes butter, cheese and other foods high in cholesterol(胆固醇). This led the British scientists to examine another important part of the French diet - red wine. Several earlier studies have suggested that people who drink proper amounts of alcohol may reduce their risk of heart disease. The British team experimented with cells from the blood vessels of cows. The scientists studied the effects of twenty-three kinds of red wine on the cow cells. They found that poly-phenols from all of the red wines stopped production of a protein called endothelin(内皮素). This protein causes blood vessels to become smaller. Scientists believe endothelin is linked to hardening of the blood vessels, which is a cause of heart disease. The scientists found that the decrease in endothelin levels was linked to the amount of poly-phenols in the wines. The British team performed similar experiments with two other kinds of wine, white and rose. These wines contain little or no poly-phenols because the grape skins are removed before the wine is made. White and rose wines had no effect on endothelin levels. The scientists also studied the effect of non-alcoholic juice made from red grapes. They found that grape juice slowed the production of endothelin, but was much less effective than the red wines. 1. So far as grapes are concerned, is more effective on reducing the risk of heart disease. A. the outer part of grapes B. the inner part of grapes C. the seeds of grapes D. the juice in grapes 2. What made the British scientists study another important part of the French diet? A. Traditional French diet. B. Lower risk of heart disease of the French. C. The reason why people drink wine. D. Poly-phenols not existing in other things. 3. From this passage, we may know people"s health is linked to . A. diet habits B. their genes C. their education D. living surroundings 4. What"s the best title for this passage? A. A Healthy Diet B. Protecting Your Heart C. Red Wine and Health D. A Study on Health | |||

| Camels are large animals living in dry areas. There are two species of camels: the Arabian camel with a single hump from the dry desert, and the Bactrian camel with two humps from Centraland East Asia. Camels are over 7 feet tall and weigh over 1,600 pounds. They will live up to 40 to 50 years . Most camels are domesticated(驯化)and fed by people. Camels are plant-eaters. Camels are very strong animals with wide, padded feet. They have thick leathery pads on their knees and chest. Camels have nostrils(鼻孔)that can open and close, protecting them from the desert environment. Bushy eyebrows and two rows of long eyelashes protect their eyes from sand. Their mouth is extremely tough, allowing camels to eat thorny(带刺的)desert plants. Their widened feet help them move without sinking into the sand. Their thick coats reflect sunlight, and also protect them from the intense heat from desert sand. Their long legs help by keeping them further from the hot ground. Camels can go without food and water for 3 to 4 days. They do not store water in their humps as is commonly believed. The humps are actually a container of fat. Camels are incredibly(难以置信) well-adapted to their environment. When conditions heat up, camels can increase their own body temperature, which prevents sweating and therefore water loss. They may not sweat at all during the day. Camels are sometimes called "ships of the desert" because people ride them around the hot, dry deserts of the world. However, the number of camels is becoming smaller for various reasons. 1. According to the passage, camels usually live in . A. Asia B. Africa C. America D. Australia 2. Paragraph 2 is mainly about . A. camels are useful animals B. camels are clever animals C. camels" body structure and function D. camels" characteristics and habits 3. The reason why camels lose little water in deserts is that they . A. get water from green foods B. can adjust their temperature C. store enough water in the humps D. can manage without water 4. What will the author probably talk about following the last paragraph? A. Ways to protect camels. B. Habitats of camels. C. Reasons for raising camels. D. Functions of camels. | |||

| As they migrate (迁徙), butterflies and moths choose the winds they want to fly with, and they change their body positions if they start floating in the wrong direction. This new finding suggests that insects may employ some of the same methods that birds use for traveling long distances. Scientists have long thought that insects were simply at the mercy of the wind. Fascinating as their skills of flight are, migrating behavior has been difficult to study in insects because many long distant trips happen thousands of feet above ground. Only recently have scientists developed technologies that can detect such little creatures at such great heights. To their surprise, though, the insects weren"t passive travelers in the winds. In autumn, for example, most light winds blew from the east, but the insects somehow sought out ones that carried them south and they positioned themselves to navigate directly to their wintering homes. Even in the spring, when most winds flowed northward, the insects didn"t always go with the flow. If breezes weren"t blowing in the exact direction they wanted to go, the insects changed their body positions to compensate. Many migrating birds do the same thing. The study also found, butterflies and moths actively flew within the air streams that pushed them along. By adding flight speeds to wind speeds, the scientists calculated that butterflies and moths can ravel as fast as 100 kilometers an hour. The findings may have real-world applications. With climate warming, migrating insects are growing in number. Knowing how and when these pests move could help farmers decide when to spray their crops. 1. What"s the main idea of the text? A. Insects migrate with the seasons. B. The wind helps insects greatly in migrating. C. Windsurfing insects have real direction. D. Scientists have trouble in observing insects. 2. Scientists originally thought that _____________. A. insects always waited for their favorable winds B. insects chose the winds they wanted to ride C. insects were just blown about by the wind D. insects positioned themselves in the winds 3. It is not easy to study the migrating behavior of the insects because _____________. A. the little creatures can fly very fast B. they have no regular migrating courses C. the wind"s direction is hard to foresee D. their flight is long and high above ground 4. We can learn form the text that _______________. A. insects fly in the way birds do B. insects travel more easily in autumn C. insects never position themselves when flying low D. insects rest a lot when the wind pushes them along |
