Sharks have been swimming in the ocean for millions of years. They were on Earth even before dinosaurs! At the top of the world's ocean's food chain, sharks help keep the population of other ocean animals in balance. A large drop in the number of sharks can cause serious problems for all ocean animals. Saving sharks makes sense! Many people are afraid of sharks. But most sharks are harmless. Only a small percentage of sharks are known to attack humans. It adapt well to new habitats and eat whatever is available. However, today, sharks are in trouble. Nearly one-third of the 400 shark species are in danger of extinction, largely due to over-fishing. Each year, tens of millions of sharks are caught and killed just for their fins . The fins are used to make shark fin soup. Humane Society International (HSI) joined with the Jane Goodall Institute's Roots and Shoots program and Beijing Zoo to protect sharks. An exhibit at the zoo, "the Price Behind the Taste-----Protect Sharks. Don't Eat Shark Fins", was designed to tell people that shark finning is cruel and unnecessary. It's hoped that the activity will help put an end to _ . Shark fin soup is also eaten in the United States. In fact, the numbers of some shark species in US waters have dropped 90 percent in the last 30 years. To slow the fall, laws against the sale of shark fins have been passed in several states, including Hawaii, Oregon, Washington, and California. What do we know from the text?

Q: There is an interesting, but at the same time a sad phenomenon now: there is a rise in the number of singers and bands that have little to do with good music.Many singers or bands know little about what good music means.What is the cause of this rise? Most of these singers have taken music as a "job" because it is a good source of making money.And if you have a good appearance and also expensive clothes to show off at your concerts or at different appearances in public, then your voice is not as important as it should be.The public will prefer to admire more the most interesting parts of your body, whether you are a girl or a boy.They will even forget about the fact that you are there to show your music skills, not your dancing, which is important too, but not at such a high level. Therefore, we can see many young girls on TV who look very good but who have nothing to do with music.They choose to wear very provocative clothes to catch attention, but when it comes to singing they are a complete mess and one doesn't need to have an ear for music to notice their lack of talent.But anyway, they have concerts and they enjoy travelling from one place to another.It is the public's fault because they accept this and are pleased with this commercial music.People who enjoy this kind of music are generally young people while adults prefer listening to old good bands. However, the young generation should understand while appearance is important, it is less important than talent and a good voice.If somebody has a great voice and wants to become a singer, he should take some special courses in this area, because they will help them improve singing abilities. What do you think is the author's attitude towards the rising number of new singers and bands? A) Critical. B) Supportive. C) Tolerant. D) Worried.

More than 15 million Britons, many of them women, will holiday unaccompanied this year. And they will no longer be treated as second-class citizens. After 50 years of being slighted, ripped off, herded together and allocated the worst rooms in the hotel, the single traveller's time has finally come. Rather than being viewed as an awkward peculiarity in the standard couples-and-families "system", single travelers have become travel's fastest growing sector and a phenomenon that tour operators are falling over themselves to catch up with. In one sense, the boom is the result of people postponing marriage and children. Approximately 39% of the adult British population--19 million people--is now single and the proportion of one-person households has increased from 18% in 1971 to 29% last year. The most significant growth of singles over the next few years is expected to be within the well-off, travel-hungry 25-34 age group. The expansion in single travel is being increased by women. Women are just as happy as men to leave partner at home and head off on holiday. On adventure group trips single women constitute more than half of all travelers, and Internet agents report that 70% of their single clients are women. Women today see being single as an opportunity to travel, rather than as an obstacle. The result is that travel companies are now attempting to work out new ways of attracting singles----a market worth PS10.4 billion. The number of specialist singles tour operators has risen from a couple to at least 10, but they face a growing challenge from mainstream operators, who now propose to target solo travelers with moves like abolishing single room supplements. At the moment, single travelers usually have to join a group, or pay more. As soon as we get beyond that, the singles market is going to take off to a completely new level. Travel companies are reacting to changing trends by _ . A) trying to find travel partners for singles B) charging more for one-person room occupancy C) encouraging solo travelers to join groups D) specializing in singles holiday requirements
