More and more people like keeping pets, so pet hospitals are usually very busy. Kind persons who love animals are needed to provide help in busy pet hospitals. Those vets (兽医) will teach them how to take care of the pets.

    Scientists think that pets will probably be much smaller because people in the future will live in much smaller space. Scientists are now working on making very small farm animals. The same thing might be done to make small cats and dogs.

    It's said that one day you might own a panther (豹) as a pet. Some scientists believe that they might have to start turning wild animals into pets since this might be the only way to save them from dying out.

    What about buying a robot to be a pet? This may sound silly, buy it could become true. Robot dogs have been made to sell. They are like real dogs. These pets might become more and more popular in the future.

    Lots of people want pets while they are on holidays. A hotel in Minnesota has solved this problem. They lend cats to their guests. Many experts (专家) believe that this idea will become more and more popular. It is very possible that in the future you will be able to order a pet, as well as room service, at a hotel.

    Giraffes are beautiful, smart and friendly. They have long legs and necks (脖子). They are so tall that they can grow up over 5 meters (米). So how do they sleep or drink?

    You may think it's difficult for them to sleep, but they have no such problems because giraffes don't often stop for a sleep. Giraffes just need to sleep about thirty minutes a day. When they sleep, they don't always lie down (躺下). They usually sleep for minutes at a time, because it's difficult for them to get up again. And it's a great danger to sleep in the wild (荒野). But the giraffes in the zoo sleep for about 4-6 hours every day. They usually lie down when they sleep.

    Drinking water is a big problem for giraffes because their long necks are too "short". To drink water, they must spread (伸展) their front legs in a difficult way. And in this way, other animals like Africa's big cats can easily hunt (猎食) them. So they usually get most of their water from the trees and flowers. Giraffes don't need to drink water very often. They can even drink no water for months!

I am a Grade 9 student. I have {#blank#}1{#/blank#} problem, and I do not know how to deal {#blank#}2{#/blank#} it. I have a lot of homework every day, and I have no choice {#blank#}3{#/blank#} to do it. I often stay up late to complete my {#blank#}4{#/blank#}, and then feel tired the next day. Sometimes I want to {#blank#}5{#/blank#} to do so much work, but usually I just accept it. I understand that {#blank#}6{#/blank#} is important to do my homework on time. However, I hardly have any {#blank#}7{#/blank#} time for my hobbies, such as playing volleyball and ping-pong. I really feel bad about that. I often doubt whether it is worth {#blank#}8{#/blank#} so hard.

I am {#blank#}9{#/blank#} forward to a holiday without homework so that I can relax and have some time for my hobbies. What should I do? Can you offer ni e some {#blank#}10{#/blank#}?

Are you interested in robots? If so, try out robot Little Q at our science center from August Ist to August 6th. Little Q is a cute robot with a round head, two big eyes and two long legs. It's like a big toy that our children will love.
