The scientific world continues to be amazed by the speed of the development of cloning. Some scientists now suggest that the cloning of humans could occur in the near future. Despite the benefits of cloning, however, certain ethical questions concerning the possible abuse of cloning have been raised. At the heart of these questions is the idea of humans influencing life in a way that could harm society, either morally or in a real physical sense. Some people object to cloning because it allows scientists to "act like God" in the handling of living organisms. The cloning of Dolly raised the debate over this practice to a whole new level. It has become obvious that the technology for cloning Dolly could also be used to clone humans. A person could choose to make two or ten or a hundred copies of himself or herself by the same techniques used with Dolly. An active debate about the morality of cloning humans arises. Some people see benefits from the practice, such as providing a way for parents to produce a new child to replace one dying of a fatal disease. Other people worry about humans taking into their own hands the future of the human race. At the beginning of the twenty-first century, many scientists say the controversy over the ethics of cloning humans is overstressed because of the unpredictability of cloning in general. While scientists have cloned animals such as sheep, mice, cows, pigs, and goats, fewer than 3 percent of all those cloning efforts have succeeded. The animal clones that have been produced often have health problems. Scientists believe the rapid reprogramming in cloning can introduce random errors into a clone's DNA. Those errors have altered individual genes in minor ways, and the genetic defects have led to the development of major medical problems. Some scientists say this should make human cloning out of the question, but others argue that cloning humans may actually be easier and safer than cloning animals. Whatever, I agree that further research in the field of... We can learn from the text that _ . A) cloning of humans is a very controversial issue B) the cloning of Dolly begins to raise the debate over cloning of humans C) there are medical problems in cloning animals D) cloning humans is easier and safer than cloning animals

For some students, especially those from poor families, taking a job is not a matter of choice, but necessity. They need to work to save for college, or even to supplement family income. Counselors should help students who have a real need to work improve time management skills and seek employment that helps their educational goals. "College costs are high, and young adults also want the amenities that extra money brings," according to John B. Boshoven, counselor for continuing education at Community High School in Michigan. However, he warns, "School is my students' full-time job." Studies show that students who work are more confident and possess better time management skills than students who are not employed. In addition to offering a paycheck, some independence, and satisfaction, a part-time job can provide teenagers with both training and experience. Working teaches students about responsibility and can also reinforce what they are learning in school. "Colleges want to find candidates who demonstrate maturity, responsibility, independence, and initiative, and good workers certainly demonstrate those important character traits," Boshoven says. "Employers can write excellent recommendation letters for the students who have worked for them." On the other hand, experts agree that students who work more than 15 to 20 hours per week often experience lessened school success, which can lead to dropping out entirely. Working long hours can also limit opportunities to build friendships and explore interests that enhance a teenager's intellectual and emotional development. The major point that students should keep in mind is the importance of balance. Dan Crabtree, college and career counselor at Wheaton Academy in Illinois, explains, "We want our students to establish a healthy balance in life and work to maintain it throughout their lives." If working will interfere with completing school work, participating in extracurricular activities, spending time with family and friends, or getting enough rest, it may... What's the purpose of the passage? A) To show how students can find a part-time job. B) To discuss the issue of students' part-time work. C) To stress the importance of students' part-time work. D) To explain what is a part-time job.

Ques: Our village, Cinderland, was founded in 2000. It is a fully-sustainable eco-village on the Big Island of Hawaii located about 29 miles southeast of Hilo and 9 miles east of Pahoa. And it is within easy walking distance of the coastline--one mile north of Hwy 132, just off Hwy 137. Solar power supplies our electrical needs, and water catchment tanks hold enough rain water for our use. Fruit trees and vegetable gardens are located throughout our tropical landscape and can be harvested at any time by the residents for their own personal consumption . We accept all lifestyles and belief systems, and encourage individuality and diversity. A good attitude and an easy-going manner are most important to us; those qualities go a long, long way here! Tuesdays are a fun and big day here. In the morning, we all get together for a few hours for various work projects. In the afternoon, many will hop in the truck for a trip to the town of Pahoa. That evening, we then are all treated to what is well-known throughout this region as "Taco Tuesday". Anyone is welcome to join us from the surrounding areas, which makes for a large gathering each week. It's certain that drummers and other musicians will be playing around the fire pit each "Taco Tuesday". With the exception of the few hours of work on Tuesdays, residents are free to do whatever they please. Some just relax, while others may snorkel , surf, swim, shop, backpack, camp, go sightseeing, watch the lava flow, etc. It's rare that someone leaves this area without feeling it is a life-changing experience. There are also many who decide to make it their permanent home. We are very welcoming. Come to give us a visit! Mahalo! Where will we probably find the text? A) In a travel note. B) In an advertisement. C) In a newspaper story. D) In a textbook.
