Read the article and select the best answer. Article: About 18,000 refugees from Burma have come to the United States each year since 2007. Some have settled in Howard County, Maryland between Baltimore and Washington. A local school began teaching English to the children of the refugees. But while the children learned the language, their parents did not. That made communication with teachers _ . At present, almost fifty children from Burma attend Bollman Bridge Elementary School. Laurel Conran is a teacher there. She said, "The main idea is the global idea." She teaches English to speakers of other languages. One of her students is Tha Neih Ciang. Another student is Tha Neih's mother, Tin Iang. Ms. Conran practices English with Tin Iang at the mother's workplace. Many refugees from Burma work at Coastal Sunbelt Produce, a supplier of fruits and vegetables to restaurants and other businesses. Laurel Conran started classes at the company to help refugees from Burma learn English. Laurel Conran said, "The program is a six-week session. It's once a week, on every Wednesday, from twelve to one o'clock. So every Wednesday I go to Coastal Sunbelt." As the workers eat lunch, they also practice their new language skills. Lisa Chertok has a child at Bollman Bridge. She is also a manager at Coastal Sunbelt. She helped Ms. Conran develop the lessons, which she says have really helped. Lisa Chertok said, "Well, when the Burmese employees got here, they were very, very shy. Now I find that they are more outspoken than before. They're more communicative. As parents, they are also more involved in their children's school." Jonathan Davis is the headmaster of Bollman Bridge Elementary School. Mr. Davis hopes the lessons will help these parents feel better about communicating with the school. He said, "Even as simple as making a phone call to say that their son or daughter is sick, even if that's the amount of English that they have got from the program, that truly will help us." Question: What can we learn about Laurel Conran from the passage? Options: A: She mainly teaches English to the local children in a school. B: She worked at Coastal Sunbelt Produce before being a teacher. C: She teaches not only English but also other languages. D: She often goes to the refugees' company to teach them English.

Read the article and select the best answer. Article: Batteries can power anything from small sensors to large systems.While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves.University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient. "To provide enough power, we need certain methods with high energy density ",said Jae Kwon, assistant professor of electrical and computer engineering at MU."The radioisotope battery can provide power density that is much higher than chemical batteries." Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems (M/NEMS).Although nuclear batteries can cause concerns, Kwon said they are safe. "People hear the word 'nuclear' and think of something very dangerous," he said, "However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems." His new idea is not only in the battery's size, but also in its semiconductor .Kwon's battery uses a liquid semiconductor rather than a solid semiconductor. "The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure of the solid semiconductor," Kwon said, "By using a liquid semiconductor, we believe we can minimize that problem." Together with J.David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery.In the future, they hope to increase the battery's power, shrink its size and try with various other materials.Kwon said that battery could be thinner than the thickness of human hair. Question: According to Jae Kwon, his nuclear battery _ . Options: A: uses a solid semiconductor B: will soon replace the present ones. C: could be extremely thin D: has passed the final test.

Read the article and select the best answer. Article: I was asked in an email about learning idioms in a foreign language. Maybe I am different from most people,but I do not bother with them. To me they are kind of dessert of language learning. They come at the end of a meal. Once you have filled up with the key words and phrases that are used in a variety of situations,then you can add a few idioms. And by that time, you will be able to pick them up naturally anyway. I find that many learners have trouble with idioms,as if repeating some very colloquial expressions is going to upgrade how they sound in a language. In fact, it is the opposite. Idioms are difficult to use correctly. Yes,occasionally you hear idioms and do not understand. But,in my experience,there are always situations where you do not understand. It is best to focus on the most important words,what they mean and how they are used. Certainly,it is best for a nonnative speaker to stick to standard speech. Some teachers even try to teach the "real language".Then you hear nonnative speakers saying things like "I goanna", "You wane" etc. You will learn all the idioms you need just by exposing yourself to the language. In general,you can save any phrase that you find interesting,and if that includes idioms,go to it. But I would not make any special effort to go after idioms. I,in fact,avoid them. If I come across something in Russian that strikes me as a particularly idiomatic use of words,I just leave it aside; do not even bother trying to learn it. If it keeps on appearing,then I will learn it. Question: How did the writer develop the passage? Options: A: By inferring. B: By comparing. C: By listing examples. D: By giving explanations.
