It allows individuals to stay in touch with friends and family, no matter where they are located. Social media also provides a platform for sharing news and information quickly and easily, which can be beneficial in emergency situations.However, social media also has negative impacts on society. One of the biggest concerns is the spread of fake news and misinformation. With the rise of social media, it has become increasingly difficult to distinguish between reliable sources and fake news. This can lead to a misinformed public and have serious consequences for society.Furthermore, social media can have a negative impact on mental health. Studies have shown that excessive use of social media can lead to feelings of loneliness, anxiety, and depression. The constant comparison to others on social media can also lead to low self-esteem and self-worth.In conclusion, while social media has its benefits, such as connecting people and sharing information, it also has negative impacts on society, such as the spread of fake news and negative effects on mental health. It is important for individuals to use social media responsibly and critically evaluate the information they see online.以上是一份英语四级考试题目模拟及答案，希望对大家备考有所帮助。

大学英语四级模拟试卷321(题后含答案及解析)题型有：1. Writing 2. Reading Comprehension (Skimming and Scanning) 3. Listening Comprehension 4. Reading Comprehension (Reading in Depth) 8. TranslationPart I Writing (30 minutes)1．For this part, you are allowed 30 minutes to write Job Problems for College Graduates. You should write at least 120 words following the outline given below in Chinese. 1.目前大学生找工作的状况。

2．存在这种状况的原因。

3．我们应该采取什么措施。

正确答案：Job Problems for College Graduates Nowadays, college graduates find it more and more difficult to get a rewarding job, and worst of all, many of them can’t find jobs in their specialties. But why does that take place? The possible reasons are as follows. Firstly, what the students have learned in colleges or universities can’t meet the demand of the development of industries. For another, the students haven’t been taught how to combine the theory with practice. Secondly, it’s hard to make a choice between a well-paid job and a favorite one. Some graduates may give up their majors or pursuit only to seek more money. Thirdly, there’s an oversupply of graduates in certain fields and this supply is still increasing now. Most students tend to choose such majors, which they think society needs and will offer them better job prospects. As a result, many of them fail to enter the profession for which they are trained. To solve the problems, we should get the students out of ivory tower to gear their courses to the needs of industries and business, and help students seek a way of living a more significant life.Part II Reading Comprehension (Skimming and Scanning) (15 minutes)Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions attached to the passage. For questions 1-7, mark：Y (for YES) if the statement agrees with the information given in the passage;N (for NO) if the statement contradicts the information given in the passage;NG (for NOT GIVEN)if the information is not given in the passage.Make a Mummy Tomb Introduction Ancient Egyptians believed in life after death. Wealthy Egyptians made careful preparations for their dead by mummifying their bodies and providing them with tombs supplied with equipment, food, clothing, ornaments, furniture, statues of gods, and workers -- everything they would need in their new lives. Make a replica of an Egyptian tomb complete with a mummy case, wall paintings, and treasures for fun or as a group project. Or choose to make just one tomb treasure or a wall painting. Each part of this Try This! is a project in itself. Before you begin, consult books about ancientEgypt to get ideas about what tombs were like and what treasures they held.Make an Egyptian tomb model By turning a rectangular(长方形的)box on its side, you can create a model tomb. You’ll need to decorate the three interior walls with paintings. Ancient Egyptians often painted tombs with scenes of daily life—dancing, hunting, playing, feasting, and working—and the journey into the afterlife. YOU WILL NEED books about ancient Egypt cardboard wooden box that measures at least 12 to 14 inches (30 to 36 centimeters) long and 9 to 10 inches (23 to 25 centimeters) wide ruler pencil drawing paper watercolor paints or felt-tip markers fine-tipped paintbrush white glue OPTIONAL one cup (230 milliliters) flour 2/3 cup (156 milliliters) water large bowl spoon strips of newspaper Here’s How 1. Find a cardboard or wooden box and turn it on its side. The bottom of the box will form the long back “wall” of your tomb. Tear off any flaps. Then measure the walls of your tomb. 2. Cut pieces of drawing paper to fit the three different walls of your tomb. 3. Make a grid of squares across each sheet with a ruler. Egyptian draftsmen scored tomb walks in a grid pattern before artists started drawing. This helped the artists compose their work and make it exact. 4.On each sheet draw your picture and use the grid to help you form rows of hieroglyphs(象形文字). 5.Erase extra lines that don’t form part of your drawing, and then paint your scene. Let your painting dry. 6.Optional: Mix the flour and water together in a bowl. Dip the newspaper strips into the mix and add one layer around the outside top and sides of your box. Let this dry. Then paint the outside of your box a sandy color. The walls’ roughness will make it look like your tomb was formed from reek. 7. Once your box is dry, glue your drawings to the walls of your tomb.Make a mummy case A mummy was often placed in one or more mummy cases to help protect it. Sometimes mummy cases were placed into sarcophaguses (石棺). The cases displayed a portrait of the dead person, images of Egyptian gods, and hieroglyphic writing. Make one for your model tomb. YOU WILL NEED books about ancient Egypt and New Kingdom mummy cases pencil sheet of cardboard scissors masking tape one cup (230 milliliters) flour 2/3 cup (156 milliliters) water large bowl spoon two or three sheets of white paper towels white glue paintbrushes acrylic (丙烯酸的) paints Hint: Do this project in stages over three or four days. Allow time for the papier-mache to dry completely. Here’s How 1 .Print pattern screens one and two. Cut the shapes out. You should have a lid, a bottom, and two narrow strips that will be the sides of the case. 2. Take each pattern piece and place it ,on a piece of cardboard. Trace around each shape with a pencil. Then cut the cardboard shapes out. If you need help, ask an adult. 3. If you don’t want to work with papier-mache you can make a simpler mummy case by skipping to Step 7. 4. Tape the cardboard strips to the base of the case. 5. Cut the paper towel sheets into short narrow strips about 1 inch (2.5 centimeters) long. 6. Mix the flour and water together in a bowl. See directions for papier-mache. Glue the lid pattern to the cardboard lid. Then shape areas of the face and feet by dipping the paper towel strips in the papier-mache mix and molding them on the lid. Make sure you cover all areas of your case with at least one layer of strips. 7. Let your case dry for two or threedays. As the lid hardens, bend it slightly so that it stays flat. 8. Once the halves of the mummy case are dry, paint them all over with white glue. Let them dry to a glossy sheen. 9. Paint a portrait on your mummy case. Add hieroglyphs, magic symbols, and pictures of Egyptian gods. Look at books for inspiration.Make some tomb treasures YOU WILL NEED books about ancient Egypt clay, store-bought modeling compound, or homemade modeling compound acrylic paints fine-tipped paintbrush Hint: To make some objects, you may need additional materials: scraps of white cloth for a sail, tiny pieces of paper for papyrus mils, thread for boat’s rigging. You can make jewelry with tiny beads and wire or thread. Small plastic figurines that you find around your house can be transformed into Egyptian statues of gods or animals by applying molding compound and sculpting features. Here’s How 1. Look through books about ancient Egypt tomb furnishings for objects you would like to create. Books and Web sites about Tutankhamun’s tomb will be especially useful. Robbers ransacked most Egyptian tombs in ancient times, but King Tutankhamun’s tomb is remarkable because it was discovered mostly intact. The tomb contained hundreds of objects, including food, clothing, furniture, chariots, baskets, weapons, musical instruments, statues, jewelry, tools, lamps, mummies, writing equipment, and more. Check out our slide show for ideas. Here are some furnishings that could be found in either Middle Kingdom or New Kingdom tombs. 2. Use modeling compound or clay to make a few objects.3.When tile objects are dry, paint them, and put them in your model tomb. Now your Egyptian tomb is complete.2．From this article, we can learn that it is teaching us how to build an old Egyptian building.A．YB．NC．NG正确答案：B解析：本题在问“本文是在教我们如何建造古埃及建筑”这一表述是否正确。

Those who are at ease on conversation have the ability to "connect" with others, which helps them build rapport (友好关系) and, eventually, relationships. Mastering 1 at small talk can be an important step in your professional development and can actually help you get ahead.Initiating a small talk requires a(n) 2 line. Not the kind of "line" you might hear in a bar or nightclub, but one that sounds 3 and lets the other person know you"re interested in talking with him. Don"t open up with a 4 . Make sure what you say has a positive spin.The real art in small talk comes in how you keep the conversation 5 . So don"t monopolize (独占) the conversation. Ask a question of the other person and really listen to his response. Then 6 on what he said with comments from your own personal experience and ask another question. Good conversationalists are people keeping up with the news and being 7 involved in life. The final step in small talk is the ending. A subtle way to signal that you"re ready to end the conversation is to break eye contact. A 8 word like "Well" can also communicate that it"s time to stop. Also, you can tell the other person you truly enjoyed talking with him and hope to have the chance to talk again.

大学英语四级备考模拟题及答案2016年大学英语四级备考模拟题及答案Part II Reading Comprehension (35 minutes)Directions: There are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center. Passage OneQuestions 21 to 25 are based on the following passage.There is a difference between science and technology. Science is a method of answering theoretical questions; technology is a method of solving practical problems. Science has to do with discovering the facts and relationships between observable phenomena in nature and with establishing theories that serve to organize these facts and relationships; technology has to do with tools, techniques, and procedures for implementing the finding of science.Another distinction between science and technology has to do with the progress in each.Progress in science excludes the human factor. Scientists, who seek to comprehend the universe and know the truth within the highest degree of accuracy and certainty, cannot pay attention to their own or other people's likes or dislikes or to popular ideas about the fitness of things. What scientists discover may shock or anger people-as did Darwin's theory of evolution. But even an unpleasant truth is more than likely to be useful; besides, we have the choice of refusing to believe it! But hardly so with technology; we do not have the choice of refusing to hearthe sonic boom produced by a supersonic aircraft flying overhead; we do not have the option of refusing to breathe polluted air; and we do not have the option of living in a non-atomic age. Unlike science progress, technology must be measured in terms of the human factor. The legitimate purpose of technology is to serve people in general, not merely some people; and future generations, not merely those who presently wish to gain advantage for themselves. Technology must be humanistic if it is to lead to a better world.21. The difference between science and technology lies in that _____.A) the former provides answers to theoretical questions while the latter to practical problemsB) the former seeks to comprehend the universe while the latter helps change the material worldC) the former aims to discover the inter-connections of facts and the rules that explain them while the latter, to discover new designs and ways of making the things we use in our daily lifeD) all of the above22. Which of the following may be representative of science?A) The improvement of people's life.B) The theory of people's life.C) Farming tools.D) Mass production.23. According to the author, scientific theories _____.A) must be strictly objectiveB) usually take into consideration people's likes and dislikesC) should conform to popular opinionsD) always appear in perfect and finished forms24. The author states that technology itself _____.A) is responsible for widespread pollution and resource exhaustionB) should serve those who wish to gain advantage for themselvesC) will lead to a better world if put to wise useD) will inevitably be for bad purpose25. The tone of the author in this passage is _____.A) positive B) negative C) factual D) critical Passage TwoQuestions 26 to 30 are based on the following passage.Americans have always been ambivalent in their attitudes toward education. On the one hand, free and universal public education was seen as necessary in a democracy, for how else would citizens learn how to govern themselves in a responsible way? On the other hand, America was always a country that offered financial opportunities for which education was not needed: on the road from rags to riches, schooling-beyond the basics of reading, writing, and arithmetic-was an unnecessary detour.Even today, it is still possible for people to achieve financial success without much education, but the number of situations in which this is possible is decreasing. In today's more complex world, the opportunities for financial success is closely related to the need for education, especially higher education.Our society is rapidly becoming one whose chief product is information, and dealing with this information requires more and more specialized education. In other words, we grow up learning more and more about fewer and fewer subjects.In the future, this trend is likely to continue. Tomorrow's world will be even more complex than today's world, and, to manage this complexity, even more specialized education will beneeded.26. The topic treated in this passage is _____.A) education in general B) Americans' attitudesC) higher education D) American education27. Americans' attitudes toward education have always been _____.A) certain B) contradictory C) ambitious D) unclear28. Today, financial success is closely related to the need for _____.A) higher education B) public education C) responsible citizens D) learning the basics29. It can be inferred from the third paragraph that _____.A) information is our only productB) education in the future will be specializedC) we are entering an age of informationD) we are living in an age of information30. Which of the following is the best title for the passage?A) The History of American Education.B) The Need for Specialized Education.C) The Future of the American Educational System.D) Attitudes toward American Education. Passage ThreeQuestions 31 to 35 are based on the following passage.A growing world population and the discoveries of science may alter this pattern of distribution in the future. As men slowly learn to master diseases, control floods, prevent famines, and stop wars, fewer people die every year; and in consequence the population of the world is steadily increasing. In 1925 there were about 2,000 million people in the world; by the end of the century there may well be over 4,000 million.When numbers rise the extra mouths must be fed. New landsmust be brought under cultivation, or land already farmed made to yield larger crops. In some areas the accessible land is so intensively cultivated that it will be difficult to make it provide more food. In some areas the population is so dense that the land is parceled out in units too tiny to allow for much improvement in farming methods. Were a large part of this farming population drawn off into industrial occupations, the land might be farmed much more productively by modern methods. There is now a race for science, technology, and industry to keep the output of food rising faster than the number of people to be fed. New strains of crops are being developed which will thrive in unfavorable climates: there are now farms beyond the Arctic Circle in Siberia and North America; irrigation and dry-farming methods bring arid lands under the plough, dams hold back the waters of great rivers to ensure water for the fields in all seasons and to provide electric power for new industries; industrial chemistry provides fertilizers to suit particular soils; aeroplanes spray crops to destroy locusts and many plant diseases. Every year some new means is devised to increase or to protect the food of the world.31. The author says that the world population is growing because _____.A) there are many rich valleys and fertile plainsB) the pattern of distribution is being alteredC) people are living longerD) new land is being brought under cultivation32. The author says that in densely populated areas the land might be more productively farmed if _____.A) the plots were subdividedB) a large part of the people moved to a different part of the countryC) industrial methods were used in farmingD) the units of land were made much larger33. We are told that there are now farms beyond the Arctic Circle. This has been made possible by _____.A) producing new strains of cropsB) irrigation and dry-farming methodsC) providing fertilizersD) destroying pests and disease34. Which of these words is nearest in meaning to the word "strains"?A) types B) sizes C) seeds D) harvests35. The author's main purpose is to _____.A) argue for a belief B) describe a phenomenonC) entertain D) propose a conclusion Passage FourQuestions 36 to 40 are based on the following passage.For some time past it has been widely accepted that babies-and other creatures-learn to do things because certain acts lead to "rewards"; and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological(生理的) "drives" as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise.It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome.Papousek began his studies by using milk in the normal way to "reward" the babies and so teach them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had had enough to drinkwould refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children's responses in situations where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement "switched on"a display of lights-and indeed that they were capable of learning quite complex turns to bring about this result, for instance, two left or two right, or even to make as many as three turns to one side.Papousek's light display was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the lights closely although they would "smile and bubble" when the display came on. Papousek concluded that it was not primarily the sight of the lights which pleased them, it was the success they were achieving in solving the problem, in mastering the skill, and that there exists a fundamental human urge to make sense of the world and bring it under intentional control.36. According to the author, babies learn to do things which .A) are directly related to pleasure B) will meet their physical needsC) will bring them a feeling of success D) will satisfy their curiosity37. Papousek noticed in his studies that a baby .A) would make learned responses when it saw the milkB) would carry out learned movements when it had enough to drinkC) would continue the simple movements without being given milkD) would turn its head to right or left when it had enough to drink38. In Papousek's experiment babies make learned movements of the head in order to .A) have the lights turned onB) be rewarded with milkC) please their parentsD) be praised39. The babies would "smile and bubble" at the lights because .A) the lights were directly related to some basic "drives"B) the sight of the lights was interestingC) they need not turn back to watch the lightsD) they succeeded in "switching on" the lights40. According to Papousek, the pleasure babies get in achieving something is a reflection of .A) a basic human desire to understand and control the worldB) the satisfaction of certain physiological needsC) their strong desire to solve complex problemsD) a fundamental human urge to display their learned skills。
