Article: BEIJING -- The launch of a new manned space mission brings China closer to the establishment of a permanent space station, international experts say. Chinese taikonauts, Jing Haipeng, 50, and Chen Dong, 37, were _ into space onboard Shenzhou-11 at 7:30 am Monday and will spend 30 days in the Chinese space laboratory Tiangong-2.The launch marks a key step toward China's plan to eventually operate a permanent space station. The successful launch of the Shenzhou-11 spacecraft is another step forward to put China among leading players in space technology, said Alexander Zheleznyakov, a Russian expert on history of space flights. China's experimental space lab will help provide solutions for spacecraft of different functions to approach and anchor, and for a long-term operation of life support system, said Zheleznyakov. Shenzhou-11 is scheduled to anchor on Wednesday with Tiangong-2, which is part of China's plan to build a permanent space station by 2022. China can now test technologies for cargo spacecraft anchoring, life support system operation and water recycling to ensure a long-term continuous operation of its space station in the future with less dependence on renewal from the Earth, he said. If all goes well, China will launch the unpiloted Tianzhou-1 cargo ship next spring to autonomously tie up with Tiangong-2. Tianzhou-1 will be capable of automatically transferring rocket fuels, a vital requirement for space station grouping and maintenance, according to a report by Columbia Broadcasting System (CBS). "That will further their anchoring abilities needed for the larger space station," Johnson Freese was quoted." Tiangong-2 is supposed to be able to stay in orbit for two years or longer, so that's taking them (Chinese) really close to 2019 or so. I think this will be their last big technology test phase before going to their large space station," said Freese. Question: Which of the following is designed to automatically transfer rocket fuels? - Shenzhou-11. - Tiangong-2. - Shenzhou-1. - Tianzhou-1.
Tianzhou-1.

Read the following article and select the best answer. Article: The parents of a troubled teen may feel unsure as to whom to turn to in order to find help for their child. They may feel as if they have exhausted all of their options, and sometimes they are on the verge of giving up. But there is hope. Schools for troubled teens offer discipline and in some cases, drug treatment programs that can provide important life skills, and more importantly, a fresh start. The following is a list of the most effective types of schools for troubled teens. Not every facility is a match for every child, but by knowing the differences between them, parents can make a better educated decision about where to send their teenager. Boarding Schools When a child is unable to deal with the relative freedom of a standard school day, boarding schools might be a good choice. At boarding schools, the child lives in a dorm setting, where almost every minute of the day is scheduled by school administrators. Treatment Centers When a teenager has an addiction to drugs or alcohol, a residential center that specializes in young people is an outstanding way to help them break the cycle of addiction. Treatment centers feature individual and group counseling to help identify the root causes of the drug problem and help develop the life skills needed to stay clean when the program is over. Wilderness Programs Designed to help improve the discipline and self-reliance of the child, wilderness programs send kids back to nature. By placing them in a foreign and sometimes uncomfortable setting, wilderness programs hope to improve children's behavior. Programs generally include hikes, exercise programs and team building exercises. Boot Camps Boot camps are the most extreme style of school for troubled teens. These facilities are modeled after actual military boot camps, where the individual must get into shape, work as part of a team, and follow a long, hard set of rules and regulations. However, boot camps might not be the best choice for a teen with a drug addiction. Question: Who would be the intended readers of the passage? - Teachers. - Parents. - Students. - Experts.

Read the following article and select the best answer. Article: The other day, I received a most unexpected message in response to one of my essays:I am so proud of you and all you have accomplished. I shared your opinion ... It was signed Margaret Leibfried, who was my English teacher -- a teacher who appeared at a vital point in my life and helped me believe that I could become a writer. Thirty years ago, I entered high school as an introvert made all the more shy because I was the school's only nonwhite student. I always felt in danger of being swept away by a sea of tall white athletes. I spent a lot of time alone, reading and writing stories, hoping to escape being teased. Ms. Leibfried taught American literature and composition grammar, which involved the usual memorizing vocabulary, but also, thrillingly, reading novels. Thrilling to me, that is. Many of my classmates expressed dislike for novels because they were "not real." For once, I didn't care what they thought. Ms. Leibfried seemed to notice my interest in both reading and writing, and she took the time to make me feel less shy; she even offered me reading suggestions, like one of her favorite novels, "The Bell Jar." That year's big project was a book report, to be read aloud to the class. However, Ms. Leibfried suggested I do something "a little different." Instead of a report, I chose a passage from "The Bell Jar" that I considered as the best to recite. The morning of the presentations, I remember my hands sweating so badly as I walked to the front of the class that I kept my hands crossed, so I wouldn't wipe them on my blouse. When I finished, to my surprise, the class applauded. "Marie has picked out a particularly sensitive piece of writing and delivered it beautifully," Ms. Leibfried said, smiling. I felt, maybe for the first time, confident. Question: What was the author's purpose in writing the text? - To express her thanks to her teacher. - To discuss the issue of racial prejudice . - To introduce one of her favorite books. - To suggest the ways to gain confidence.
To express her thanks to her teacher.
