Article: Legend has it that sometime toward the end of the Civil War (1861 - 1865) a government train carrying oxen was caught in a snowstorm and had to be abandoned. The driver returned the next spring to see what had become of his cargo. Instead of the skeletons he had expected to find, he saw his oxen, living, fat, and healthy. How had they survived? The answer lay in a resource that unknowing Americans had trampled underfoot in their haste to cross the "Great American Desert" to reach lands that sometimes proved barren. In the eastern parts of the United States, the preferred grass for forage was a cultivated plant. It grew well with enough rain, then when cut and stored it would cure and become nourishing hay for winter feed. But in the dry grazing lands of the west, that familiar blue joint grass was often killed by drought. To raise cattle out there seemed risky or even hopeless. Who could imagine a fairy-tale grass that required no rain and somehow made it possible for cattle to feed themselves all winter? But the surprising western wild grasses did just that. They had wonderfully convenient features that made them superior to the cultivated eastern grasses. Variously known as buffalo grass, not only were they immune to drought, but they were actually preserved by the lack of summer and autumn rains. They were not juicy like the cultivated eastern grasses, but had short, hard stems. And they did not need to be cured in a barn, but dried right where they grew on the ground. When they dried in this way, they remained naturally sweet and nourishing through the winter. Cattle left outdoors to fend for themselves thrived on this hay. And the cattle themselves helped plant the fresh grass year after year, for they trampled the natural seeds firmly into the soil to be watered by the melting snows of winter and the occasional rains of spring. The dry summer air cured them much as storing in a barn cured the cultivated grasses. Question: According to the passage, the cattle helped promote the growth of the wild grasses by _ . Yes or no, is the answer "stepping on and pressing the seeds into the ground"?
Yes

Article: An inventor seeks to create a new product that serves a specific need and fulfills a role that other products do not. Sometimes an inventor comes up with a wholly new idea, but more often inventions are simply improvements on an older design. With a little imagination and creativity , an old idea can suddenly become something new. However, creating a new invention means much more than having a brilliant idea. A good designer follows the design process: identifying the challenge, researching and brainstorming ideas , designing a solution, testing and evaluating the ideas, and finally building the product. Designers also use science, math, technology, and engineering to design a tool that satisfies the need they identified. Anyone can be an inventor --even kids! For example, Chester Greenwood was just fifteen years old when he invented a product that changed his life. In fact, his idea was so good that his invention supported him for the rest of his life. You may not know his name, but you probably know his invention --earmuffs ! The inspiration for his earmuff design came to Chester when he was ice-skating. His ears were cold, and he decided to find a way to keep them warm. With the help of his grandmother, he made a new product to protect his ears and at the age of eighteen, Chester patented his earmuff design. Many other famous inventors started young as well. Margaret Knight --the inventor of the flat-bottomed brown paper bag --is said to have created a safety device for textile looms when she was just twelve years old. Another example is Thomas Edison, one of the greatest inventors in history, who applied for his first patent when he was just twenty-one years old. Over the course of his life, Thomas Edison patented a total of 1,093 inventions! Question: At first Chester designed his earmuffs in order to _ . Yes or no, is the answer "protect his ears while ice-skating"?
Yes

Q: Article: A new study of 8,000 young people in the journal ofHealthandSocialBehaviorshows that although love can make grownups live healthily and happily,it is a bad thing for young people.Puppy love may bring trouble for young people and can cause depression .The study shows that girls become more depressed than boys,and young girls are the worst of all. The possible reason for the connection between love and higher risk of depression for girls is "loss of self".According to the study,even though boys would say "lose themselves in a romantic relationship",this "loss of self" is much more likely to cause depression when it happens to girls.Young girls who have romantic relationships usually like hiding their feelings and opinions.They won't tell that to their parents. Dr.Marianm Kaufman,who works on young people problems,says 15% to 20% of young people will have depression during their growing.Trying romance often causes the depression.She advises kids not to jump into romance too early.During growing up,it is important for young people to build strong friendship and a strong sense of self.She also suggests the parents should encourage their kids to keep close to their friends,attend more interesting school activities and spend enough time with family. Parents should watch for their children's eating or mood changes.If they see some,they need to give help.The good news is that the connection between romance and depression seems to become weak with age.Love will always make us feel young,but only maturity gives us a chance to avoid its bad side effects. Question: According to the passage,the author _ puppy love. Yes or no, is the answer "is against"?

Article: It's been seven days since a 7. 0-magnitude strong earthquake hit Ya'an, in Sichuan Province. How the earthquake has affected one of Sichuan Province's special residents--pandas. How are the animals coping? And do they have enough food to eat? There are more than 80 pandas living here at the Chengdu Panda Breeding Base. 7 baby pandas have just left their mothers and have begun to learn how to fend for themselves. The quake was felt strongly in Chengdu. Fortunately, all of the pandas here were out on the grounds when the earthquake hit, so they were very safe. Although no deaths or injuries have been reported among the Baoxing panda population so far, they've been badly frightened by the earthquake. Several days has passed and the earthquake seems to have made no discernible negative impact on the pandas. These two baby pandas Chengshuang and Chengdui are play fighting with each other and climbing trees. When they climbed too high, the breeders have to rescue them from the trees. The visitors are amused by the scenes and think it's like a fantastic acrobatics show. The quake zone is not only the home of these pandas, it's also the source of their food. Fortunately, enough bamboo has been stored away in five bamboo storehouses for the pandas, so there are no worries with regard to food supplies. Wu Kongju, Breeder, Chengdu Panda Breeding Base, said, "When the Wenchuan earthquake happened in 2008, we were unprepared and had a shortage of bamboo. But we've been able to handle this earthquake event more smoothly. There are no problems with the food supply. "Apart from the pandas' favorite Baijia Bamboo, breeders also give them bamboo shoots, which are very rich in nutrients. Wu Kongju said, "Bamboo shoots contain more protein than ordinary bamboo, and they're also very succulent because they contain more water. " Question: What's the author's attitude towards the reaction of Chengdu Panda Breeding Base? Yes or no, is the answer "Supportive."?
