I'm taking a test and have to guess the right answer to the question after the article. Article: Idioms are phrases and sentences that do not mean exactly what they say. Even if you know the meaning of each word you see or hear, you may not understand the idiom because you don't understand the culture behind it. For example, if an American boy asks his mother what's for dinner tomorrow, she may say "I'll play it by ear", that means she doesn't have plans for dinner and she will decide later. "Play by ear" used to mean playing music using the sheet music, but now people often use it when they're not talking about music. There're many idioms in English. If you learn to use them, your English will be more vivid and colorful. English idioms are more common in spoken English. They can be difficult to remember sometimes. Next time when you hear somebody saying to you, "Give me a hand", you don't necessarily stretch out your hand to him/her, but you do need to be helpful. And when the situation is out of hand, you usually can do very little to manage all that. What about a green hand? It's not about the color of your hand! You're a green hand when you are very new at your work and don't have much experience. If you and your partner always work together hand in glove, you two definitely work together very well. Can you guess the meanings of some common English idioms to do with parts of your body? Question: When one says "Can you give me a hand?", he means _ . Options: A: he needs to hold your hand. B: he works well with you C: he needs your help D: he is a new comer and can't help with the situation

I'm taking a test and have to guess the right answer to the question after the article. Article: Love to sink into your chairs and relax when you get to school? Then you will not be happy to hear that schools all over the world are seriously considering exchanging traditional desks for ones with no seats at all -- Yes, that means you will be encouraged to stand through those already too long math and science lessons! Why would anyone even think of putting kids to such cruelty? Experts say it improves their health and helps fight obesity. While that may seem a little far-fetched , the officials at the few schools around the world seem to agree. Among them are educators from the College Station Independent School District in Texas, who recently completed a week-long experiment involving 480 students across three elementary schools. The 374 kids that agreed to participate in the study were provided with a device that helped record step count and calorie consumption over the entire period. All 25 teachers involved in the study reported that students appeared to be more alert and concentrate better, when allowed to stand. The one thing that did surprise the researchers was that younger kids were more willing to stay standing than kids in higher grades. They believe this may have something to do with the fact that after years of being asked to "sit still", older kids have a harder time adjusting to this unexpected freedom. American schools are not the only ones reporting success with stand-up desks. Four Catholic schools in Perth, Australia, which have been testing them since October 2013, have seen similar results. In May 2014, Grove House Primary School in Bradford, West Yorkshire, became Europe's first test one, with a seven-week trial that involved the use of desks made by Ergotron in their fifth-grade classrooms. While official results are not out yet, early reactions from both teachers and students, have been extremely encouraging. The findings of these studies and others done previously, all seem to mean that allowing kids to move around in classrooms is a win-win for students and teachers -- it helps... Question: Why do the teachers like the standing desks? Options: A: Because the educators can draw the students' attention. B: Because the teachers can keep the students healthy. C: Because the students can have a walk in the classroom.. D: Because the standing desks can keep the students concentrated.

I'm taking a test and have to guess the right answer to the question after the article. Article: Some years ago I was offered a writing assignment that would require three months of travel through Europe. I had been abroad a couple of times,but I could hardly claim to know my way around the continent. Moreover, my knowledge of foreign languages was limited to a little college French. I hesitated. How would I, unable to speak the language, totally unfamiliar with local geography or transportation systems, set up interviews and do research? It seemed impossible, and with considerable regret. I sat down to write a letter begging off. Halfway through, a thought ran through my mind: you can't learn if you don't try. So I accepted the assignment. There were some bad moments. But by the time I had finished the trip I was an experienced traveler. And ever since,I have never hesitated to head for even the most remote of places,without guides or even advanced bookings, confident that somehow I will manage. The point is that the new, the different, is almost scary by definition. But each time you try something, you learn, and as the learning piles up, the world opens to you. I've learned to ski at 40, and flown up the Rhine River in a balloon. And I know I'll go on doing such things. It's not because I'm braver or more daring than others. I'm not. But I'll accept anxiety as another name for challenge and I believe I can accomplish wonders. Question: We can infer from the text that the author is _ .

I'm taking a test and have to guess the right answer to the question after the article. Article: An American spacecraft is moving closer to a dwarf planet called Ceres . The American space agency's Dawn spacecraft is set to reach the planet-like object in March. Space agency scientists will then place Dawn in an orbit around the dwarf planet. Agency scientists want to know more about ice on Ceres. The spacecraft will gather clues about whether Ceres may have once had conditions to support life as we know it. Dawn left Earth more than seven years ago on a trip to explore Ceres and another dwarf planet, called Vesta . Both dwarf planets are in the main belt of asteroids , a group of large objects, between the planets Mars and Jupiter. Marc Rayman is the chief engineer and director of the Dawn mission. Scientists call Vesta and Ceres "protoplanets ". Mr. Rayman says they were in the process of becoming full-size planets when, in his words, "their growth was terminated ." Scientists believe Ceres is made of rock, and covered with ice. The Dawn mission is based in Los Angeles, California. Scientists there send second-by-second commands to the spacecraft. They direct its every move, including telling it what pictures to take. Dawn will make a map of the dwarf planet. It will also try to discover how Ceres' surface has changed. Carol Raymond is the deputy principal investigator of the project. He says Dawn made an unexpected discovery while orbiting Vesta. "Instead of being bone dry, which we expected, there were _ on the surface of Vesta that showed significant amounts of water bound in the rocks and possibly even free water that could have flowed on the surface in the past." She says that if Earth's water came from wet worlds like Vesta and Ceres, then life could have developed there, too. If Dawn finds that the environment of Ceres could have supported life, scientists may seek to explore the dwarf planet with other scientific instruments. Dawn will gather information about Ceres until the middle of 2016. It will then continue to orbit the small planet. Question: The passage mainly tells us _ . Options: A: Spacecraft , Dawn, is researching Ceres. B: What Spacecraft , Dawn, is. C: NASA Spacecraft, Dawn, is moving closer to a 'Dwarf Planet'. D: How Dwarf Planet research program is carried out.
