As you can see，water works hard in your body every day.That’s why it’s important? to give your body the water it needs to carry out all its different jobs.On a regular day，your body loses 2 to 3 quarts of water—enough to fill a 2?liter soda bottle.You probably guess that water is lost when you sweat—especially?? on a hot day.

But your body also loses water in an almost invisible way—evaporation (蒸发)．Water escapes from your body through your skin and in your breath.How？Your breath contains droplets (小滴) of water that are usually too tiny to see.They become visible for a quick second in the cold when you can “see your breath”．But water evaporates this way all year round.Your skin also contains water，which escapes in tiny droplets that go into? the air.The water in your skin evaporates into the air，but fortunately，your body can replace the water it loses so your skin doesn’t dry out.

Eating and drinking is one way to replace the water your body loses.Most foods have a lot of water in them，especially fruits and vegetables.Grapes，watermelons，oranges，and cantaloupes are delicious and full of water.

But you can’t rely_on food alone to get that water back，and that’s why it’s also a good idea to drink water? every day.You might have heard someone say that people need to drink 6 to 8 cups (1.4 to 1.9 liters) of water each day.Depending on how much? water you’re getting from foods and other liquids,6 to 8 cups might not be necessary.If you eat a lot of fruits and vegetables，or you like to eat soup every day，you’ll get some of the water your body needs.

　　Humans not only love eating ice cream, they enjoy feeding it to their pets. Market studies show that two thirds of all dog owners give ice cream to their dogs. Unfortunately, says William Tyznik, an expert on animal nutrition (营养) at Ohio State University, ice cream is not good for dogs. “It has milk sugar in it,” He says,“which dogs cannot digest very well. ”

　　Bothered (拓扰) by that knowledge but aware (having idea) of the desire of dog owners to please their companions, Tyznik invented a new frozen treat for dogs that, he says, in more nutritious that ice cream-and as much fun to eat. The product, called Frosty Paws, is made of a liquid byproduct(副产品) of cheese and milk with the sugar removed. Frosty Paws also contains refined soy flour, water, vegetable oil, vitamins and minerals. It took Tyznic, who has also invented a horse food (called Tizwhiz) and another dog food (named Tizbits), three years to perfect the Frosty Paws formula, and two attempts, to commercialize it. After losing $ 25,000 trying to market the invention himself, Tyznik sold the rights to Associated Ice Cream of Westerville. Ohio, which makes the product and packages it in cups.

　　Tyznik claims that Frosty Paws has been tested extensively and that “dogs love it. ”Of , 1,400 dogs that have been offered the product, he says, 89 percent took it on the first try. Three out of four preferred it to Mild-Bone or sausages. The ■section of supermarkets, comes in packs of three or four cups ,costing between $ 1.39 and $ 1.79.

　　What would happen if a human should mistake Frosty Paws for real ice cream? Nothing says Tyznik. It's harmless , but frankly , he says , it won's taste very good.

Surrounded by the towns of Davidson, Huntersville and Cornelius, Lake Norman is a man-made lake. It is also the largest lake in the state covering a shoreline of more than 500 miles. State Park on the lake gives a chance for different water activities.
People, both tourists and locals, come to the area on weekends, where during the peak season a large crowd arrives to relax and have fun. A great activity for kids is education except fun. The tour covers aquatic(水生的) life, especially that seen at Lake Norman. Since it is more of an educational one it also covers other important knowledge about water.
Those wanting to go boating are seen off into the lake on canoes and pedal boats which are rented on hourly basis. The charges are $5 per hour increased by $3 for every additional(附加的) hour. The boats can be kept on the lake all day from 10 in the morning till 5 in the evening during the summers. Both canoes and pedal boats can seat 2 to 4 people.
The park also set up a group tent camp, where a site can hold about 25 people. People from all over the country come here to catch some fishing action, obviously hoping to catch some fish as well. The inner park lake is also great for fishing, though it offers a smaller area compared to Lake Norman. Those here for adventure like to go for biking and hiking on the trails inside the park.
Lake Norman is a great place to spend time with family and friends. People come here on vacation or simply to kick back after a week’s work and relax.
【小题1】From the passage we learn that Lake Norman is ______.      

Whether we’re 2 years old or 62, our reasons for lying are mostly the same: to get out of trouble, for personal gain and to make ourselves look better in the eyes of others. But a growing body of research is raising questions about how a child’s lie is different from an adult’s lie, and how the way we deceive changes as we grow.
“Parents and teachers who catch their children lying should not be alarmed. Their children are not going to turn out to be abnormal liars,” says Dr. Lee, a professor at the University of Toronto and director of the Institute of Child Study. He has spent the last 15 years studying how lying changes as kids get older, why some people lie more than others as well as which factors can reduce lying. The fact that children tell lies is a sign that they have reached a new developmental stage. Dr. Lee conducted a series of studies in which they bring children into a lab with hidden cameras. Children and young adults aged 2 to 17 are likely to lie while being told not to look at a toy, which is put behind the child’s back. Whether or not the child takes a secret look is caught on tape.
For young kids, the desire to cheat is big and 90% take a secret look in these experiments. When the test-giver returns to the room, the child is asked if he or she looked secretly. At age 2, about a quarter of children will lie and say they didn’t. By 3, half of kids will lie, and by 4, that figure is 90%, studies show.
Researchers have found that it’s kids with better understanding abilities who lie more. That’s because to lie you also have to keep the truth in mind, which includes many brain processes, such as combining several sources of information and faking that information. The ability to lie — and lie successfully  — is thought to be related to development of brain regions that allow so called “executive functioning”, or higher order thinking and reasoning abilities. Kids who perform better on tests that involve executive functioning also lie more.
