Researchers used frozen DNA to produce a clone, but the newborn kid died within minutes of birth due to breathing difficulties. The Pyrenean ibex is a type of mountain goat,which is believed to have died out completely in 2000. Before the death of the last known individual(a13-year-old female known as Celia), biologists took cells from her skin and ears. An earlier cloning attempt to use the skin cells failed. But the latest attempt involved the creation of 439 cloned embryos. Of these cloned embryos, 57 were put into the female domestic goats, but only one goat gave birth and the newborn cloned kid died after seven minutes as a result of lung disease. Researchers say that other cloned animals, including sheep, have been born with similar lung disease, but they say that overall the experiment was a major step forward in the effort to bring the ibex back to its mountain home. The leading researcher Jose Folch says, "the cloned kid was genetically like the ibex;in species such as the ibex,cloning is the only possibility to avoid its complete disappearance." The failure to produce a living clone from DNA that was frozen only a decade ago shows the difficulty researchers would face in trying to bring back species that have been extinct for decades or centuries. Researchers have had the idea of bringing back the Tasmanian tiger, which went extinct in 1936. There are, however, other species that have been seriously suggested for cloning,such as the giant panda, the African bongo antelope, the Sumatran tiger and the pygmy hippo. Supporters believe cloning provides hope of keeping these endangered animals alive before they die out. Question: What do we know about the cloned ibex? Options: A: It died of lung disease. B: It was the first cloned animal in the world. C: It lived for thirteen years. D: It was born in 2000.

Read the article and select the best answer. Article: We don't have beds in the space shuttle, but we do have sleeping bags. During the day, when we are working, we leave the bags tied to the wall, out of the way. At bedtime we untie them and take them wherever we've chosen to sleep. On most space shuttle flights everyone sleeps at the same time. No one has to stay awake to watch over the space plane: the shuttle's computers and the enginers at the Control Office do that. If anything goes wrong. The computers ring a warning bell and the engineers call us on the radio. On the space shuttle, sleep-time doesn't mean nighttime. During each ninety-minute flight around the earth, the sun "rises" and shines through our windows for about fifty minutes: then it "sets" as our flight takes us around the dark side of the Earth. To keep the sun out of our eyes, we wear black sleep masks. It is surprisingly easy to get comfortable and fall asleep in space, and we sleep differently. Some sleep upside down, some sideways, some right side up. When it's time to sleep, I take my bag, my sleep mask, and my tape player with earphones and float up to the flight platform. Then I get into the bag, and float into a sitting position just above a seat, right next to a window. Before I pull the mask down over my eyes, I relax for a while, listening to music and watching the Earth go by under me. When I'm in space I don't need as much sleep as I do on Earth Maybe that's because when I am weightless, I don't feel as tired. Or maybe it's because I'm excited to be in space and don't want to waste time sleeping. Question: What does the passage mainly talk about? Options: A: How to live in space B: How they sleep in space C: How to fall asleep in space D: How the space shuttle functions

Ques: Read the article and select the best answer. Article: Net Library is a library that lends out digital books. It treats a digital book like a paperback copy. It charges libraries per book per copy and gives publishers a cut of the total income. From the consumer's point of view, this means that if more than five people want the latest Danielle Steel romance novel, other people who request that book will get a message saying the title is unable to get. Many publishers seem to have embraced its model. More than 350 publishers gave the company rights to hand out their digital works, and McGraw-Hill Corporation and Houghton Mifflin Corporation have put money into the company. The California public libraries and about 1,800 others across the US are trying out the Net Library service. Some librarians criticize the Net Library model. Stanford University librarian Michael Keller argues that the company is creating an unnatural fear of digital works, which is contrary to the ideas of the Internet. Keller and some other librarians argue for the e-book vision set forth by Brary. Brary is starting a service that lets us users read books for free. But it will charge about 25 cents a page when a person tries to point out material or copy and taste it into a different file or tries to download a copy onto a computer. Christopher Warnock, chief executive of Brary, believes most consumers won't want to buy entire books, only the parts that interest them. "There is not really a lot of good owning an electronic file and having to store it and manage it. It doesn't make sense," he said. Question: How do publishers get money from the Net Library? Options: A: They get money from selling their books to the Net Library B: They get money from the readers. C: They get money by cutting the cost of the books. D: They share the money with Net Library.

Ques:Read the article and select the best answer. Article: If your parents were to surprise you with a present on your birthday, which one would you prefer, a trip to the amusement park or a new pair of shoes? According to Science Daily, about onethird of the people are likely to prefer shoes to a fun trip. These people are called "materialists", namely, those who value material goods more than experiences. But which of the two choices makes people happier? Back in 2009, Ryan Howell, a professor at San Francisco State University, found that in the long run, experiences make people happier than possessions. This is because the joy of receiving a new object fades over time as you get used to seeing it every day. Experiences, on the other hand, can continue to bring you joy in the future through happy memories. But materialists should at least be happy when they first buy something, shouldn't they? To figure it out, Howell did another study. He classified a group of adults according to their personality types, ranging from less materialistic to more materialistic. Each person was asked different questions to see how they felt about spending money on material goods versus spending money on experiences. As expected, the more materialistic participants got less happiness from purchases than the less materialistic, because such purchases didn't fit with their personalities and values. But to Howell's surprise, he found that materialists weren't any happier even if they spent money on material items. This is because materialists worry that others may criticize or look down on their choices. "There are certain value systems that are rejected by society," said Howell. "When we find out someone is materialistic, we think less of them, and that drives their happiness down." Another reason is that materialistic people always focus on what they don't have instead of what they have now. This makes them feel less satisfied and grateful. If you happen to be a materialistic person, there's something you can try. "If materialists make more accurate purchases, rather than trying to... Question: What did Ryan Howell want to find out by doing another study? Options: A: How to judge whether a person is a materialist. B: Why materialists are not happy with their purchases. C: How materialists feel when they spend money on goods. D: Whether materialists are happy when they first make purchases.
