The Drink Your Body Needs Most

1 Our bodies are estimated to be about 60% to 70% water. Blood is mostly water and our muscles, lungs, and brain all contain a lot of water. Water is needed to regulate body temperature and to provide the means for nutrients (滋养物) to travel to all our organs. Water also transports oxygen to our cells, removes waste, and protects our joints and organs.

2 We lose water through urination (排尿), respiration (呼吸), and by sweating. If you are very active, you lose more water than if you do not take much exercise. Symptoms of mild dehydration (脱水) include chronic pains in joints and muscles, lower back pain, headaches,and constipation (便秘) A strong smell to your urine, along with a yellow color indicates that you are not getting enough water. Thirst is all obvious sign of dehydration and in fact, you need water long before you feel thirsty.

3 A good rule of thumb (好的做法) is to take your body weight in pounds and divide that number in half. That gives you the number of ounces (盎司) of water per day that you need.For example, if you weigh 160 pounds, you should drink at least 80 ounces of water per day.If you exercise you should drink another 8-ounce glass of water for every 20 minutes you are active. If you drink coffee or alcohol, you should add at least an equal amount of water.When you are traveling on an airplane, it is good to have 8 ounces of water for every hour you are on board the plane.

4 It may be difficult to drink enough water on a busy day. Be sure you have water handy at all times by keeping a bottle for water with you when you are working, traveling, or exercising. If you get bored with plain water, add a bit of lemon for a touch of flavor. There are some brands of flavored water available, but some of them have sugar or artificial sweeteners that you don&39;t need.

根据以下材料，回答题The Sahara DesertThe Sahara Desert is the largest desert in the world.

根据以下材料，回答题

The Sahara Desert

The Sahara Desert is the largest desert in the world. It stretches across Africa from Senegal to Egypt. The Sahara Desert is an unfriendly environment. During the day it"s very hot， and at night it"s sometimes very cold. It is also difficult to find water in the Sahara.

In 2006， Kevin Lin， Ray Zahab， and Charlie Engle decided to do something very difficult.

They made the decision to run across the Sahara Desert 4，300 miles （6，920krn）. It seemed impossible to do， but they wanted to try. The three men liked to test themselves， and this would be a very big test.

On the morning of November 2， Kevin， Ray， and Charlie started their trip across the Sahara.

Every morning they began running at 5:00. At 11 a.m. they stopped and rested until 5 p.m. Then they ran again until 9:30 in the evening. Each day they ran about 40 miles （64 km）. Every day it was the same thing. They got up and ran. They listened to music on their iPods， and they ran and ran.

Kevin， Ray， and Charlie needed to eat a lot of food during their trip. Most people need about 2，000 calories of food each day. Kevin， Ray， and Charlie needed between 6，000 and 9，000 calories every day. That"s a lot of food! They also needed to drink a lot of water.

The three men had some problems on their trip， and many times they wanted to quit and go home. It was often very hot （140~F/60~C） during the day， and the heat made them sick. Their legs and feet hurt. Sometimes it was very windy， and they couldn"t see. One time they got lost. But they didn"t quit. After 111 days， Kevin， Ray; and Charlie successfully finished their trip across the Sahara Desert. They hugged each other and put their hands in the water of the Red Sea. Then they ran to a hotel to take a long shower.

It‘s not always hot in the Sahara Desert. 查看材料

A.Right

B.Wrong

C.mentioned

根据以下材料，回答题。

What We Take From and Give to the Sea

As long as we have been on earth， we have used the sea around us. We take things from the ocean， and we give to it.

We take fishes from the ocean——millions of kilograms of fish， every year， to feed millions of people. （46） We take minerals from the ocean. One way to get salt is to place seawater in a shallow basin and leave it until it evaporates. （47） Much gold and silver drift dissolved in the waters of the sea， too. But the sea does not give them up by simple evaporation.

Other gifts from the sea are pearls， sponges and seaweed. Pearls become jewelry. （48）Seaweed becomes food of many kinds——even candy， and ice cream——as well as medicine. Believe it or not， fresh water is another gift from the sea. We cannot drink ocean water. （49）But ocean water becomes fresh water when the salts are removed. In the future， we will find ourselves depending more and more on fresh water from the sea.

The sea gives us food， fertilizer， minerals， water， and other gifts. What do we give the sea？ Garbage. （50） Huge as it is， the ocean cannot hold all the water we pour into it Dumping garbage into the ocean is killing off sea life. Yet as the world population grows， we may

need the sea and its gifts more than ever.

We are finally learning that if we destroy our sea， we might also destroy ourselves. Hopefully， it is not too late.

A.Natural sponges become cleaning aids.

B.We pollute the ocean when we use it as a garbage dump.

C.The area of the sea is becoming smaller anal smaller.

D.Along with salt， other minerals are left after evaporation.

E.We even use their bones for fertilizer.

F.Some of its contents may cause illness.

根据以下材料，回答题

Ward off Travel Bugs

（1） As the holiday season approaches， so does the prospect of jet lag， an upset stomach or sunburn.

With care and some help fi"om natural sources， however， it is quite possible to avoid these problems.

（2） You can start to prepare a couple of weeks before you leave. Food poisoning will make any holiday miserable， but by taking some medicine such as lactobacillus and bifidobacteria， you can reduce the likelihood of poisoning caused by food or water tainted （感染，污染） with unfamiliar bacteria.

（3） By improving the bacteria balance in your digestive tract， you crowd out the pathogenic （病原的）bacteria and stop them gaining a foothold. The beneficial bacteria also produce gentle but effective natural antibiotics （抗生素） in yourgut.

（4） In many holiday locations you need to remember the basics: drink bottled water， avoid undercooked meat and ensure that food hygiene （卫生） is adequate. If you get food poisoning，drink plenty of water to stay hydrated（保持水分）and see a doctor. However， if you detect diarrhea（腹泻） early enough， you might like to try taking about 10 or 15 pancreatic digestive enzymes， which can digest the multiplying bacteria before they take over.

（5） Taking a teaspoon of silicol gel can also help. This lines the stomach and upper intestinal area and binds with bacteria and viruses， allowing them to be safely passed out of the gut. When you pack，include grapefit-it-seed extract， which is an excellent all-round anti-bacterial， anti- parasitic，anti-viral （抗毒的） and anti-fungal （杀菌的） agent.

（6） Your flight can also be made more pleasant. Peppermint oil and ginger capsules （胶囊） ward off motion sickness， but a more delicious option is to eat crystallized ginger. If you tend to get ear-ache on take-off and landing， you can use special ear plugs with filler that slows down the rate of change in air pressure.

（7） The greatest concern is "economy class syndrome"， the popular name for deep-vein thrombosis （血栓症）， which can lead to blood clots traveling from the legs to the lungs， heart or brain. To reduce this， you need a couple of hours to stay hydrated， and avoid alcohol.

（8） You can also reduce the severity of inflammation by taking a daily gram of vitamin C with the bioflavonoid quercetin. Vitamin C and quercetin also help to reduce prickly heat.

（9） Finally， if any adverse symptoms persist while overseas， you should see a doctor.

根据以下材料，回答题

Invisibility Ring

Scientists can"t yet make an invisibility cloak like the one that Harry Potter uses. But， for the first time， they"ve constructed a simple cloaking device that makes itself and something placed inside it invisible to microwaves.

When a person "sees" an object， his or her eye senses many different waves of visible light as they bounce off the object. The eye and brain then work together to organize the sensations and reconstruct the object"s original shape. So， to make an object invisible， scientists have to keep waves from bouncing off it. And they have to make sure the object casts no shadow. Otherwise， the absence of reflected light on one side would give the object away.

Invisibility isn"t possible yet with waves of light that the human eye can see. But it is now possible with microwaves. Like visible light， microwaves are a form. of radiant energy. They are part of the electromagnetic spectrum， which also includes radio waves， infrared light， ultravioletmys， X rays， and gamma rays. The wave lengths of microwaves are shorter than those of radio waves but longer than those of visible light.

The scientists" new "invisibility device" is the size of a drink coaster and shaped likearing. The ring is made of a special material with unusual ability. When microwaves strike thering， very few bounce off it. Instead， they pass through the ring， which bends the waves all the way around until they reach the opposite side. The waves then return to their original paths.

To a detector set up to receive microwaves on the other side of the ring， it looks as if the waves never changed their paths as if there were no object in the way! So， the ring is effectively invisible.

When the researchers put a small copper loop inside the ring， it， too， is nearly invisible.

However， the cloaking device and anything inside it do cast a pale shadow. And the device works only for microwaves， not for visible light or any kind of electromagnetic radiation. So， Harry Potter"s invisibility cloak doesn"t have any real competition yet.

Harry Potter is mentioned in the passage， because scientists __________. 查看材料

A.can now make an invisible cloak of the same kind as he uses

B.try to make an invisible cloak of the same kind as he uses

C.try to invent a device similar in idea to the invisible cloak he uses

D.know that it is possible to make an invisible cloak of the same kind
