Hotlines have become common in China. Some radio broadcasting stations use hotlines to encourage the listeners to take part in the talk shows. That's a good idea. Yet, the fact is, some people do nothing but break the whole program. Some people know little about the topic under discussion. Sometimes they do not even know what the host is talking about. So the host has to tell the caller what the show is about. Usually the caller will ask a few questions which express his hope and show his ignorance . Then the host has to answer and explain--how silly this is! It wastes a lot of time. It seems that some people phone the hotlines for fun. They just want to let the listeners hear them. They don't care what the topic is, whether they themselves are interested or how silly they appear to be. I'm totally bored by those people. It's necessary for radio stations to improve the hotline programmers. In my opinion, if a caller does not know what is going on, the operator should not let the caller take part in it. Some calls waste the host's time _ . A) because the host works hard B) because of the caller's ignorance C) because the host likes talking to the caller D) because of a lot of questions raised by the caller

(Question)
Last Christmas was a very difficult time for me. My family and all of my close friends were back home in Florida, and I was all alone in a rather cold California. I was working too many hours and became very sick. I was working a double shift at the Southwest Airlines ticket counter, it was about 9:00 PM on Christmas Eve, and I was feeling really miserable inside. There were a few of us working and very few customers waiting to be helped. When it was time for me to call the next person to the counter, I looked out to see the sweetest-looking old man standing with a cane. He walked very slowly over to the counter and in the faintest voice told me that he had to go to New Orleans. I tried to explain to him that there were no more flights that night and that he would have to go in the morning. He looked so confused and very worried. I tried to find out more information by asking if he had a reservation or if he remembered when he was supposed to travel, but he seemed to become more confused with each question. He just kept saying, "She said I have to go to New Orleans." After much time, I was able to at least find out that this old man had been dropped off at the curb on Christmas Eve by his sister-in-law and told to go to New Orleans, where he had family. She had given him some cash and told him just to go inside and buy a ticket. When I asked if he could come back tomorrow, he said that she was gone and that he had no place to stay. He then said he would wait at the airport until tomorrow. Naturally, I felt a little ashamed. Here I was feeling very sorry for myself about being alone on Christmas, when this angel named Clarence MacDonald was sent to me to remind me of what being alone really meant. It broke my heart. Immediately, I told him we would get it all straightened out, and our Customer Service agent helped to book him a seat for the earliest flight the next morning. We gave him the senior citizen's fare, which gave him some extra money for travelling. About this time he started to look very tired, and... The writer's first impression of the old man was that he was _ . A) gentle-looking and weak B) tired out and worried C) confused and very sick D) sad and anxious

Ques: BEIJING , March 9 --- The central government will require an additional three years of use for official vehicles for ministers and governors to reduce the costs of purchasing new cars, media have reported. The new rule has been applied among all Party and government departments nationwide, theBeijing Newsreported on Tuesday. The new rule has not yet been made public, said Li, a member of the Chinese People's Political Consultative Conference National Committee. Under the old rules, the cars used by minister-level officials could be replaced as often as every five years, Li said. These officials will also keep the same cars when they assume new posts, he added. The new rule also reiterated that officials ranking below minister-or-governor-levels should not be allocated cars. The cars possessed by their departments should be used on demand. "It violates the rules for lower-ranking --- even county-level-officials to be allocated cars," Li said. Purchases of vehicles for official use have been heavily investigated, as they account for a large expenditure of public funds every year. A survey on the Web news www.ifeng.com found 64 percent of respondents believed the new rule will be difficult to carry out because it is related to officials' interests. "Local government departments had halted approvals for requests for such vehicles and had started to work on new quotas under the new rules," Li said. "The future reform of official vehicle use will introduce market mechanisms and monetization." Premier Wen Jiabao said in the annual government work report on Saturday that expenditures on such vehicles will not increase in 2011 compared with a year ago. Beijing's standing deputy mayor Ji Lin last week said the municipal government will release the number of vehicles for official use in the capital as early as at the end of this month. Earlier this month, the Minister of Finance had published a rule regulating the budgets for such vehicles. What is the public's attitude toward the new rule's fulfillment? A) Uncertain. B) Optimistic. C) Indifferent. D) Passive

Ques:Orcas, or killer whales, are the largest of the dolphins and one of the world's most powerful animals feeding on meat. They feast on marine mammals such as seals, sea lions, and even whales, employing teeth that can be four inches (ten centimeters) long. They are known to grab seals right off the ice. They also eat fish, squid , and seabirds. Though they often frequent cold, coastal waters, orcas can be found from the polar regions to the Equator . Killer whales hunt in deadly groups, family groups of up to 40 individuals. There appear to be both permanent and temporary group populations of killer whales. These different groups may hunt different animals and use different techniques to catch them. Permanent groups tend to prefer fish, while temporary groups target marine mammals. All groups use effective, cooperative hunting techniques that some are similar to the behavior of wolf packs. Whales make a wide variety of communicative sounds, and each group has various noises that its members will recognize even at a distance. They use echolocation to communicate and hunt, making sounds that travel underwater until they meet objects, then reflect back, showing their location, size, and shape. Killer whales are protective of their young, and other adolescent females often assist the mother in caring for them. Mothers give birth every three to ten years, after a 17-month pregnancy. Killer whales are immediately recognizable by their special black-and-white coloring and are the intelligent, trainable stars of many aquarium shows. Killer whales have never been widely hunted by humans. We can conclude that _ . A) people can find killer whales everywhere around the world B) killer whales live in different groups and never live alone C) by making sounds killer whales hunt and communicate D) humans' hunt has made killer whales being endangered
