During the seasons of fine weather, kids can play outside, happy and active. But when winter comes around, it is wet, windy and cold. Since they can't go outside to play, kids get restless and miserable. Fun activities for kids are pretty much necessary at that time of year, and they need to be kept entertained. One way to do this is to have an indoor treasure hunt, where children can look for clues and then get to the treasure. Treasure doesn't even need to be much, because just the activity is fun enough. Art activities are always fun, and if you start off with some paper in different colors they can draws shapes on the back, cut them out and stick them on the white paper to make all sorts of things. Cardboard boxes, stuck together and then painted, can be made into buildings or robots. You can keep all boxes in a bag in the loft. Then you have something you can draw on when the weather is bad and the children need to play indoors. Dressing up is another fun indoor activity. Why not read a book to them and then ask them to act it for you? That can keep them busy and develop their imagination. When you encourage children to use their imagination, you are giving them confidence in themselves, in their own creative abilities; by suggesting they put on a play you are encouraging them to work together and develop teamwork skills. The best way to help your kids have fun when it is rainy outside is to let them come up with some ideas. When you feel that they are old enough, let them write their ideas on a piece of paper and you can pick an idea that you find practical. That way, every day can be fun! Kids are most likely to be unhappy in winter because _ . A) it is very cold and windy B) they lead a miserable life C) they like spring very much D) they can't enjoy themselves outside

A villa designed to resist earthquakes with "self-healing" cracks in its walls, thanks to nanotechnology applications with self-healing polymers , is to be built on a Greek mountainside. The villa's walls will include special particles that turn into a liquid when squeezed under pressure, flow into cracks, and then harden to form a solid material. The NanoManufacturing Institute (NMI), based in Leeds University, will play a key role in an EU project to construct the home by December 2010. The project, called "Intelligent Safe and Secure Buildings" (ISSB) is funded under the EU's Sixth Framework program. This potentially life-saving scheme is led by German building manufacturer Knauf. The villa will be built in Amphilochia, in western Greece, where Knauf currently runs a manufacturing plant. If the experiment is successful, more tremor-resistant homes could be built in earthquake zones across the globe. NMI chief executive Professor Terry Wilkins said, "What we're trying to achieve here is very exciting. We're looking to use polymers in much tougher situations than ever before on a larger scale." Monitors contained in the villa's walls will be able to collect vast amounts of data about the building over time. Wireless sensors will record any stresses and vibrations, as well as temperature, humidity and gas levels. The walls are to be built from new load-bearing steel frames and high-strength gypsum board. Prof Wilkins said, "If there are any problems, the intelligent sensor network will be able to alert residents immediately so they have time to escape. If whole groups of houses are so constructed, we could use a larger network of sensors to get even more information. If the house falls down, we have got hand-held devices that can be used over the ruins to pick out where the embedded sensors are hidden to get some information about how the villa collapsed. Also, we can get information about anyone who may be around, so it potentially becomes a tool for rescue." The villa can resist earthquakes because _ . A) it will be built on a special place B) the cracks in its walls can be healed by the polymers C) the special particles can make its walls stronger D) the intelligent sensor network can tell people where there is a crack

Ques: When you enter a supermarket, you see shelves full of food. You walk between the shelves. You carry a shopping basket and your food is in it. You probably hear soft, slow music as you walk between the shelves. If you hear fast music, you walk quickly. The supermarket plays slow music. You walk slowly and have more time to buy things. Maybe you go to the meat department first. There is some meat on sale, and you want to find it. The manager of the supermarket knows where customers enter the meat department. The cheaper meat is at the other end of the meat department, away from where the customers enter. You have to walk by all the expensive meat before you find the cheaper meat. Maybe you will buy some of the expensive meat instead of the meat on sale. The department selling milk and milk products such as butter and milk powder is called the dairy department. Many customers like milk that has only a little butterfat in it. One store has three different jars of low fat milk. One says"1 percent fat"on the jar. The second says "99 percent fat free". The third says "LOW FAT" in big letters and"1%"in small letters. As you can see, all the milk has the same amount of fat. The milk is all the same. However,in this store the three jars of milk cost three different amounts of money. Maybe the customers will buy the milk that costs the most. Most of the food in supermarkets is very pleasing. It all says "Buy me!" to the customers. The expensive meat says "Buy me!"as you walk by. The expensive milk jar says "Buy me! I have less fat." There are three different jars of low fat milk, and _ . A) one has more fat than the other two B) they all cost the same amount of money C) one has less fat than the others D) they all have the same amount of fat
Ans: D
Ques:The largest bird that cannot fly also happens to be the largest living bird in the world. This is the huge North African ostrich . When the male is fully grown, he reaches a height of nearly eight feet and many weigh close to three hundred pounds. His wings are very small and the wing feathers are very soft, and therefore he does not fly. You have probably heard the old saying about "the foolish ostrich burying his head in the sand". Well, the ostrich is not nearly as foolish as he is said to be. In the daytime, when the hen is sitting on the eggs, she does not want to be seen; instead of sticking her long neck up into the air, she bends her neck and head down. That way, she can best protect the eggs and herself. Because the ostrich cannot fly up into the air to escape from danger on the ground, he has to remain alert at all times. Luckily, he has very good eyesight and hearing, so he can stop danger in time to run away. The ostrich can run so fast that it almost seems as if he is flying. Sometimes, when a person has a small appetite , we say that he "eats like a bird". Of course, that bird is not the ostrich! An ostrich will eat anything under the sun. When an ostrich died in a zoo, scientists cut it open to see what he had eaten. Here are some of the things found in its stomach: three pieces of wood, part of a film roll, a French coin, four pennies, and so on. Which of the following enables ostriches to escape from danger in time? A) Their height and weight. B) Very good eyesight and hearing. C) The ability to fly up into the air D) A big appetite
