I'm taking a test and have to guess the right answer to the question after the article. Article: Sandstorms hit northwestern China's Gansu Province and North China's Inner Mongolia Autonomous Region on the first day this year. According to Sun Landong,a meteorologist with the Lanzhou Meteorology Observatory,visibility was less than 100 meters in Minqin, a Gansu county near Inner Mongolia,because of sand. When visibility drops to less than 1 kilometer, it is called a sandstorm. The sandstorm in Minqin blew up dust in neighboring towns, such as Baiyin,Wuwei,Jinchang and Lanzhou,the capital city of Gansu Province Dust-laden winds also swept into Beijing. Brought by northwesterly blowing at more than 20 meters per second, dust first reached the capital's suburbs at 7 a. m.,downtown areas at 9 a. m. The winds,which died down during the night,brought the temperature down to as low as 8 0C below zero and many flights put off their planned time from the city's airport. It is quite rare for sandstorms,which are frequent between March and June,to happen in winter,when the earth is frozen. The sandstorms in Gansu and Inner Mongolia do not necessarily mean there will be more of them in the spring than last year,when they were serious,but Beijing is taking it very seriously. It is reported that Beijing will spend 6 billion yuan( US 725 million) in preventing sandstorms in the capital and has already set up a special team to make sure what causes them. Question: What is the main idea of the passage? Options: A: Sandstorms took place in Gansu. B: Sandstorms happened on the first day of the new year. C: Sandstorms are very serious,compared to last year. D: Experts are trying their best to determine the cause of the sandstorm formed this year

I'm taking a test and have to guess the right answer to the question after the article. Article: Parents need to be good role models to help their children make sensible financial decisions, according to Adam Hancock and his team, from East Caronlina University in the US. Their work highlights that parents who argue about finances contribute to increasing credit card debt among their children during their students years. Their work is published online in Springer's Journal of Family and Economic Issues. Credit card debt among college students has been a growing concern for researchers and policymakers over the last decade. In addition, there is growing concern among educators that more students are dropping out of school, not because of academic failure, but because of financial reasons, and credit card especially. Hancock and colleagues' study is the first to examine how parental interactions, and financial knowledge and attitudes may have a cumulative effect on the number of credit cards students own and their level of credit card debt. The researchers analyzed data for 420 undergraduate students from seven different American universities, who took part in the College Student Financial Literacy Survey. According to the online survey, nearly two-thirds of students had a credit card, and nearly a third had more than one. Those students who reported that their parents argued about finances were more likely to have more than two cards than the students whose parents who did not argue about finances. In terms of debt, those students who had two or more credit cards were nearly three times more likely to report having credit card debt over $500. The researchers conclude, "It is clear that the influence of parents cannot be neglected. Researchers, educators and policymakers should work in finding effective ways to increase the positive financial behaviors for college students. We need to help students learn financial skills and establish healthy financial attitudes at earlier ages to prevent poor financial habits from taking root. " Question: In Adam Hancock's research, student's credit card debt is related to their _ . Options: A: knowledge B: concerns C: school D: parents

*Question*
I'm taking a test and have to guess the right answer to the question after the article. Article: Language-learners who say they never or hardly ever use dictionaries often speak English well but usually write poorly, because they make many mistakes. The students who use dictionaries most do not learn especially well either. The ones who look up every new word do not read fast. So they do not have time to read much. Those who use small two-language dictionaries have the worst problems. Their dictionaries often give only one or two words as translations of English. But one English word often has many translations in a foreign language and one foreign word has many translations in English. The most successful students are those who use large college edition dictionaries with about 100,000 words but do not use them too often. When they are reading, these students first try to get the general idea and understand new words from the context. Then they reread and use the dictionary to look up only key words that they still do not understand. They use dictionaries more for writing. If they are not sure how to spell a word, or divide it into syllables , they always use a dictionary. Also, if they think a noun might have an unusual plural form, they check these in a dictionary. Question: According to the passage, which of the following is right? Options: A: Students who never use dictionary can speak well and write well. B: Whatever new words you meet while reading, just look them up in the dictionary. C: Small two-language dictionaries are bad for learning English. D: An English word only has one translation.

*Question*
I'm taking a test and have to guess the right answer to the question after the article. Article: The whole body is covered with skin.The surface of the skin is dead(like the hair and the nails),but it is made from a living layer just under the surface.The outside dead layers wear off all the time,with new ones replacing them,and the body forms a totally new skin every three weeks. The skin protects the body from the outside world and it passes information from the outside.It helps to keep water in the body and to keep the body at the same temperature.Becteria can't get in through the skin unless it is damaged. If the weather is cold,the blood vessels in the skin squeeze down,or contract ,so that as little blood as possible comes near the surface.This means that less warmth is lost to the outside.This makes the skin look pale,or even "blue".At the same time,the hairs on the skin are pulled upright by tiny muscles. When it is hot,the blood vessels expand ,or get wider again,to allow plenty of blood to run near the surface of the skin.This helps the body to lose heat,and the skin may look red.At the same time,the sweat glands produce more sweat,which cools the skin. If your skin has ever been numb ,you will realize how important the feeling from the skin is.Nerves in the skin are sensitive to heat and cold,sharpness,hardness and softness,wetness and dryness and pain.If one is not able to feel these things,which can act as warnings,he is likely to be burned,cut or hurt in other ways. The colour of the skin depends on special colour cells .These are just below the top layers of the skin.They are needed as protection from some harmful ray of the sun.The stronger the sun is,the more important it is to have a dark skin.People with pale skins may "tan" in the sun.This happens when the body produces extra colour cells in the skin for protection.In the sun,the skin produces a vitamin(vitamin D)which is needed for strong bones. Question: Bacteria will get in through the skin _ . Options: A: when one's skin is numb B: when one is ill C: when the skin is cut D: when the sweat glands produce more sweat
