Q: Read the article and select the best answer. Article: Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in order to cut the greenhouse gases they send out, which is thought to be responsible for global warming. Thanks to special bacteria in their stomachs, kangaroo flatulence contains nomethane and scientists want to transfer that bacteria to cattle and sheep who produce large quantities of the harmful gas. While the usual image of greenhouse gas pollution is a billowing smokestack pushing out carbon dioxide, farm animals' passing wind contributes a surprisingly high percentage of total emissions in some countries. "Fourteen percent of emissions from all sources in Australia is from enteric methane from cattle and sheep," said Athol Klieve, a senior research scientist with the Queensland state government. "And if you look at another country such as New Zealand, which has got a much higher agricultural base, they're actually up around 50 percent," he said. Researchers say the bacteria also make the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers. But it will take researchers at least three years to isolate the bacteria, before they can even start to develop a way of transferring it to cattle and sheep. Another group of scientists, meanwhile, has suggested Australians should farm fewer cattle and sheep and just eat more kangaroos. And about 20 percent of health-conscious Australians have eaten the national symbol already. "It's low in fat, it's got high protein levels and it's very clean in the sense that basically it's the free-range animal," said Peter Ampt of the University of New South Wales's institute of environmental studies. Question: Athol Klieve seems to believe that _ . Options: A: cattle and sheep produce more carbon dioxide B: less cattle and sheep are raised in New Zealand C: farm animals are to blame for the increase of greenhouse gases D: New Zealand has the most animals in the world
A: C

Q: Read the article and select the best answer. Article: We all think that we see things as they really are. But according to a new report in Psychological Science, if we really want something, that strong wish may influence how we view our surroundings . Psychological scientists Emily Balcetis from New York University and David Dunning from Cornell University did a set of studies to see how our strong wish affects perception. In the first experiment, people who voluntarily took part in the study had to estimate how far a water bottle was from where it was sitting. Half of the volunteers were allowed to drink water before the experiment, while the others ate salty cookies, thus becoming very thirsty. The results showed that the thirsty volunteers estimated that the water was closer to them than volunteers who drank water earlier. Our strong wish for certain objects may also lead to behavioral changes. In a separate experiment, the volunteers threw beanbags towards the gift cards (worth either $25 or $0) on the floor, winning the card if the beanbag landed on it. Interestingly, the volunteers threw the beanbag much farther if the gift card was worth $0 than if it was worth $25 -- that is, they underthrew the beanbag when attempting to win the $25 gift cards, because they viewed that the gift cards as being closer to them. These findings show that when we want something, we actually view it as being physically close to us. When we see a goal as being close to us, it encourages us to keep on going to successfully gain it. Question: The findings from the study seem to suggest the importance of _ . Options: A: doing separate experiments B: having clear goals C: developing normal senses D: building self-confidence
A: B

Q: Read the article and select the best answer. Article: Attending the Space Camp organized by NASA at prefix = st1 /Huntsville,Alabamais every kid's dream. It gives them the real life experience of what it is like to be an astronaut. It enriches their life with the most meaningful and interesting experiences. Most of these one-week programs are combined with other community programs. As expected, there is an age limit at the Space Camp in Alabamawith the full camp program being offered only to kids of twelve and above. Many of the activities organized at the camp are likely to be difficult for younger kids, and kids need to be old enough to stay for the week away from home. However, some special programs are offered at the center even for younger kids. The programs and activities at Space Camp are to awaken creativity. There are exercises in classes and discussions about the history of the space program. These classes include the Russian space program as well as the United Statesprogram. Trips to the museum are also provided for an educational experience. All those who attend the Space Camp go through a sort of training. They wear space suits to get the feeling of being an astronaut. They are taken into simulators to learn how to fly spacecrafts like the shuttle. And they experience the feeling of weightlessness in the zero gravity simulations. What's more, they even have equipment designed to give them the experience of walking on the moon. Space Camp is an effective and fun way to bring an interest in space and science. Kids will go through a practical program in a learning atmosphere that transports them far away from their location in Huntsville.Alabama. Question: The classes find activities at Space Camp can make kids Options: A: strong B: brave C: creative D: clever
A: C

Q: Read the article and select the best answer. Article: You've probably heard of a lot about the Internet,but what is it? The Internet is a computer network that uses the telephone system to connect together millions of computers around the world. Maybe that isn't very exciting but once you're connected to the Internet,there are lots of different things you can do.You can send electronic messages or emails to your friends (as long as they're on the Internet,too),or you can sort through all kinds of information on something called the World Wide Web. You don't need to know how the Internet works in order to use it,but if you understand the basics,it may help you work out many technical problems you have--and of course you can help your friends with your Net knowledge! You may think that your telephone is just for talking. But as long as you have the equipment, you can use a telephone line to send computer data as well as sounds. If you connect your computer with the telephone system it can receive information from, and send information to other computers (as long as they are connected with the telephone system,too). Because there is not an organization which operates the Internet,no one exactly knows how many people are connected to it. It's thought that there could be 60 million people on the Net,connected up to over 15 million computers! Question: With both your computer and telephone,you can _ . Options: A: see the others face while calling up B: receive information from other computers C: send information to other computers D: both B and C
A: D
