She fought for women's rights long before it became a popular issue.Susan was born on February 15, 1820, in Adams, Massachusetts. At that time, women had few rights. They could not own property. Money earned by a married woman belonged to her husband. Major decisions regarding children were made by the fathers. Women could not vote.At the age of 15, Susan became a schoolteacher. She taught for 15 years. Then she began organizing women's groups to promote causes that were important to women. She helped gain better educational rightsfor women. She helped give married women possession of their earnings.After the Civil War, Susan became very involved in the Woman's Suffrage Movement. After years of lecturing, writing, and appealing by Susan and other women, some parts of the United States changed their laws to give women the right to vote. The first state was Wyoming in 1869. Other areas and states gradually followed Wyoming's decision. It was not until 1920 that the U. S. Constitution was changed to give all women voting rights.Susan Brownwell Anthony died in 1906 at the age of 86. She was elected to the American Hall of Fame in 1950. She was the first American woman to have a likeness (肖像) of her face on a coin. It was the T979 Susan Brwonwell Anthony dollar.24. What was the situation of American women like when Susan was born?A. They had a low social status.B. They could vote after getting married.C. They managed money for their husbands.D. They were responsible for decision-making.25. What is the third paragraph mainly about?A. Susan's teaching experiences.B. Susan's educational background.C. Susan's efforts to abolish slavery.D. Susan's fighting for women's causes.26. What does the word "decision" in the fourth paragraph refer to?A. Promoting the social movement.B. Changing the US Constitution.C. Giving women voting rights.D. Uniting other areas and states.27. What may be the best title for the text?A. The first American woman to invent coinsB. The problem of women rights in the USC. The most popular women organizations D, A pioneer in fighting for women's rightsCCrossing your legs is an extremely common habit; most people don't even notice that they're doing it when they sit down. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason for this is that the blood in your legs has to work against gravity to be pumped back to your heart and that crossing one leg over the other increases resistance, making it even harder for the blood to circulate. This causes your body to increase your blood pressure to push the blood back to the heart. You won't feel any immediate effects, but repeated, drawn-out increases in blood pressure can cause long-term health issues. So, planning to sit for a long period of time? Don't keep your legs crossed.Crossing your legs at the knee can also cause pressure on the major nerve in your leg that passes just below your knee and along the outside of your leg, explains Richard Graves, a medical expert. This pressure can cause numbness and temporary paralysis (麻痹) of some of the muscles in your foot and leg, preventing you from being able to raise your ankle—what we know as that “pins and needles”sensation. While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.28. What can we learn about crossing one's legs?A. It is a very bad social habit.B. It is usually practiced deliberately.C. It can do harm to people's health.D. It can make others feel uncomfortable.29. According to the study, sitting with your legs crossed can______.A. affect your blood pressureB. resist gravity effectivelyC. lead to heart attacks easilyD. improve the function of legs30. In the third paragraph "pins and needles" probably means______.A. slight sharp painsB. being a little nervousC. serious muscle injuriesD. being highly flexible31. What is the main purpose of the text?A. To compare common habits.B. To give readers some advice.C. To evaluate effects of an experiment.D. To introduce research methods.DBees play a vital role in the world. Unfortunately, bees are dying by the second.The main purpose of bees is to make honey. Honey, shockingly, does not exist for human consumption, it is essential to the insects. Honeybees store honey in their hives (蜂巢) in order for the bees to have energy for their flight muscles and for heating the hive during the winter period. They collect pollen (花粉) which supplies protein for young bees to grow.According to Honey, com, the increased production and quality of agricultural crops as a result of honey bee pollination is valued &t more than1 $14/ 6 billion per year. These insects are responsible for over 70 of the fruits and vegetables we eat today, including apples, grapes, coffee, beans, and broccoli.So if they are so valuable to agriculture, why do they keep dying off? A key suspect seems to be pesticides (农药). Honeybees who are exposed to pesticides result in the damage to their neurological (神经的) functions, specifically memory or behavior. And that's why the majority of worker bees disappear and leave behind a queen, plenty of food and a few nurse bees to care for the remaining immature bees and the queen. There are several other causes to the decline of bees, including the destruction of natural habitat, like woodlands, forests, and other habitats for bees. Climate change is also a factor in the decline of the wild bee population.Actually, there are a variety of methods to help the bee population grow. One way is to start your own organic garden by planting bee-friendly plants. Pesticides are used in both industrial practices and even in your home, so it is best to find organic seeds and weed killers.32. Why do honeybees store honey in their hives?A. To provide enough honey for human to consume.B. To draw protein out of honey for young bees.C. To help attract other insects and make hives stronger.D. To strengthen bee muscles and heat hives in winter.33. Apples and beans are mentioned in the third paragraph to show that _.A. bees supply human beings with basic foodB. bees mainly live on these agricultural cropsC. bees are of great importance to fruits and vegetablesD. bees can bring in more money for famers every year34. What is most likely to cause the worker bees to leave their hives behind?A. The lack of food.B. The abuse of pesticides.C. The fighting among bees.D. The destruction of the habitats.35. What would the author probably discuss in the paragraph that follows?A. Another way to save bees.B. Other tips for choosing seeds.C. More methods to plant green organic fruits.D. Causes of the decline in the wild bee population.第二节（共5小题；每小题2分, 满分10分）Empathy, the Key to Being KindIn science class, your teacher tells everyone to find a partner for a project.

2017年安徽高考英语试卷及英语质量检测试卷(2)DUntil recently, scientists had mapped only about 20 percent of the sea floor. But our knowledge of the deep seas is changing because of information from satellites. Scientists have produced a new map that provides a detailed picture of the oceans. The map is expected to help oceanographers (海洋学家), industry and governments.The new map is twice as detailed as the map made 20 years ago. David Sandwell is a geophysics professor at the University of California. He and other scientists worked on the mapping project. He says they turned to space to look deeper into the ocean.The scientists collected and studied information from two satellites. Some of the data came from the European Space Agency’s Cryo-2 satellite. It was placed in Earth's orbit to watch sea ice. The other satellite is the American space agency's Jason-1. It is studying the surface of the oceans. Scientists combined the satellite data with images gathered by sonar (声波定位仪) equipment on ships. Sonar works by sending sound waves through the water. When the sound waves hit an object, its presence is confirmed.The new map shows the sea floor as it has never been seen before. It shows thousands of underwater mountains and places where continents pulled apart. It shows where earthquakes were active many years ago. They all are buried deep underneath the ocean floor.David Sandwell says the map is a powerful tool for fisheries, those interested in protecting the environment and for oilexploration.“The petrol exploration industry is interested in how to reconnect the continents, bring them back together tectonically so you can map the basins on one continental edge—say, Africa—and use that to establish where the similar basin would be on the other continental edge in South America.”If scientists know that information, they may be able to find oil fields. The new data also will help scientists improve their estimates of ocean depths. This information can help ships travel safely and improve military operations and scientific projects worldwide.Mr. Sandwell thinks scientists will make many more discoveries as they examine the new map and the information it provides.32. Which one is not mentioned about the benefits brought by the new map?A. Fisheries.B. Scientific projects.C. Ship manufacture.D. Oil exploration.33. What can we know about the new map?A. It shows where earthquakes will happen.B. It will be helpful to industry and governments.C. It is three times as detailed as the old one years ago.D. It shows the sea floor as it has ever been seen before.34. The text is likely to appear in _________.A. a newspaperB. an advertisementC. a science magazineD. a finance report35. Which of the following can be the best title for the text?A. The detailed picture of the oceansB. Underwater mountains and placesC. More discoveries about the oceansD. Scientists create new maps of ocean floor第二节(共5小题;每小题2分，满分10 分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
