I'm taking a test and have to guess the right answer to the question after the article. Article: As each semester begins, my colleague greets his students wearing a jacket and tie. "You make only one first impression," he says. So while the rest of the semester he teaches class in his usual, more casual clothes, the first week he presents a different image. His thought is that students will remember their first meet positively and more readily think highly of him as the semester goes on because that favorable first impression has an influence on them. The sequence that we meet matters in how we judge subsequent information. The big influence of first impressions is related to the halo effect, where the perception of positive qualities in one thing or part gives rise to the perception of similar qualities in related things or in the whole. Here is an example: You meet a friendly person at a party and later are asked to collect money for a worthy cause. You call that person because you think she will make a contribution. In reality, there is no connection between being pleasant and being generous. Yet the halo effect leads you to think that the two are related. The halo effect is powerful, but it is questionable whether it matters much in long-term relationships, such as that between teacher and student. While dressing up may make students think the teacher must know his subject matter because he creates a professional first impression, the effect wears thin if the person turns out to be a poor teacher after all. First impressions matter but they don't have the final word. Facts speak louder. If you had never seen or heard of Einstein, the first time you saw him your impression would most likely be negative. Now his face is connected with genius , not madness because he is the person who has come to define what genius is. The problem is that few of us are Einsteins and we often don't get the chance to change a negative first impression. Question: The author uses the example of Einstein to show the importance of _ . Options: A: appearance B: impressions C: truth D: fairness

I'm taking a test and have to guess the right answer to the question after the article. Article: On Sept. 11, an unseen enemy launched an attack on economic, military and governmental Landmarks of the United States. Beyond the tremendous loss of innocent lives and physical property, the attack was clearly aimed at the ideals of America--our values and the economic system that has made the U.S. economy the envy of the world. Those responsible for these acts portray the United States as the embodiment of all that is evil With globalization and the worldwide economy it has spawned. They use the failures of globalization as an excuse to exploit their millions of constituents in the underdeveloped world. Sometime soon, the U.S. military will strike back against those who it is determined have committed these acts. A military response is appropriate - some would say overdue . But even if the military objective is achieved, that alone will not get to the heart of the matter. It is crucial that the U.S. economy return to full speed ahead and continue to be the driving force behind expansion of the global economy. Globalization, or at least the present phase of it, generally is viewed as having started with the end of the Cold War in 1989. And for all its shortcomings, the free flow of goods, services, capital and labor across the borders of the world's trading nations -- the process that has come to be called globalization--still offers the best chance to fulfill the dreams of so many of the world's poor. Question: What does the passage mainly talk about? Options: A: Economical factors are of great importance in international affairs. B: The event on Sept. 11 has slowed down the process of globalization. C: Military forces are necessary in the course of the development of economy. D: The progress of globalization depends on the recovery of American economy.

I'm taking a test and have to guess the right answer to the question after the article. Article: In a society where lung and breast cancers are leading causes of cancer death worldwide, early detection of the disease is highly desirable. In a new scientific study, researchers present astonishing new evidence that man's best friend, the dog, may have the ability to contribute to early cancer detection. Researchers show scientific evidence that a dog's extraordinary smelling ability can distinguish people with both early and late stage lung and breast cancers from healthy people. Researchers first discovered this in the case report of a dog warning its owner to the presence of a melanoma by constantly sniffing the skin lesion . Later studies published in major medical magazines proved the ability of trained dogs to detect both melanomas and bladder cancers. The new study is the first to test whether dogs can detect cancers only by sniffing the breath of cancer patients. In this study, five household dogs were trained within a short 3-week period to detect lung or breast cancer by sniffing the breath of cancer patients. The experiment consisted of 86 cancer patients (55 with lung cancer and 31 with breast cancer) and 83 healthy people. All cancer patients had recently been diagnosed with cancer and had not yet undergone any chemotherapy treatment . The dogs were presented with breath samples from the cancer patients and the healthy ones, captured in a special tube. Dogs were trained to give a positive identification of a cancer patient by sitting or lying down directly in front of a test station containing a cancer patient sample, while ignoring healthy samples. The results of the study showed that dogs can detect breast and lung cancer between 88% and 97%. Moreover, the study also proved that the trained dogs could even detect the early stages of lung cancer, as well as early breast cancer. The researchers concluded that breath analysis might become a potential of cancer diagnosis. Question: The last sentence of the passage means_. Options: A: doctors won't be worried about detecting cancers any more B: dogs will be the only way to detect cancers C: breath analysis can be used in diagnosing cancers in the future D: dogs can use its smell to identify people

I'm taking a test and have to guess the right answer to the question after the article. Article: Jamie Wardley is a special kind of artist - an ice sculptor. He first trained as a sand sculptor. Later, he learned about ice sculpture. Now he does sand sculpture in the summer. And in the winter, he sculpts ice. When sculpting ice, Wardley has to work in cold temperatures. If the weather is cold enough, he can work outside. But winter in the United Kingdom is not always very cold. So often he works in a large freezer where the temperature is about -12degC. Wardley enjoys sculpting ice outside in the winter. When he sculpts in the open air, people can watch. They can be part of the creative process. Wardley makes ice sculpting sound simple. But the tools Wardley uses are sharp and dangerous. And the ice is very heavy. Each block of ice weighs 120 kilos. And some larger sculptures are made from several combined blocks of ice. Sometimes ice sculptures can be as big as buildings. In Kemi, Finland there is an ice hotel called the Snow Castle. Each year, Wardley helps build the Snow Castle. Inside the Snow Castle, the temperature is -50C. Even the dining tables are made of ice. So you have to wear winter clothes when eating and wear a hat when sleeping. "The ice hotel is built every year in January. Then it melts in April. Each year we rebuild it and create a new design," Wardley said. The Snow Castle is a large and amazing work of ice, but Wardley's smaller ice sculptures are special too. One winter, in the city of Bradford, UK, Wardley created several small sculptures. He used the sculptures to tell a story which contained an important message about good will and understanding. Ice sculptures are temporary works of art. When the temperature rises, they will melt. But that does not mean that their beauty is lost. The sculptures from that day in Bradford have now melted away, but their message of good will, understanding, and acceptance remains. Question: What do we know about the Snow Castle? Options: A: It lies in the city of Bradford, UK. B: It is too cold for people to live in. C: It requires to be built every year. D: It is built between January and April.
