When you drink a glass of water or take a shower, think of glaciers. Why? Glaciers contain at least 75 percent of Earth’s fresh water-much more than all our planet’s lakes and rivers combined.
Glaciers grow by adding a new layer of snow each year. It’s easy for scientists to see the annual layers in an ice core by lighting it from beneath. They can then count the layers to determine the age of any section…much like you can count tree rings to determine a tree’s age.
Glaciers form by the accumulation, press and recrystallization of snow. It requires very specific conditions of climate and geography, which means that they are found in or high mountain regions where snowfall is heavy in winter, temperatures stay below freezing for long periods, and summers are cool.
“Hot” ice! Is that possible? Actually, ice is one of the hottest solids in existence, for it is unsteady and easy to melt when heated. Glaciers are always moving, but because ice is hot, they like liquids rather than solids. They slide over the ground on melt-water, a very thin layer of water from melted ice, and “creep” when their icy layers glide over one another because of their weight. Different parts of the same glacier slide or creep at different speeds. The center moves more rapidly than the sides; the surface moves more rapidly than the bottom, because the sides and bottom are restricted by friction. Most glaciers move several feet per year, while others “race” a few miles.
Unfortunately, glaciers are shrinking throughout the world. Melting glaciers will raise sea levels, forcing people to move from low-lying areas.
1.What does the underlined word “it” refer to in paragraph3?
A.The change of glaciers. B.The press of glaciers.
C.The accumulation of glaciers. D.The forming of glaciers.
2.Why do we say the ice is “hot”?
A.Because it keeps sliding or creeping. B.Because it is close to its melting point.
C.Because it absorbs too much sunshine. D.Because the surrounding temperature is low.
3.What is happening to glaciers?
A.They are spreading. B.They are disappearing.
C.They are rising. D.They are racing.
4.What is the best title of this passage?
A.The History of Glaciers. B.The Development of Glaciers.
C.The Secrets about Glaciers. D.The Danger Glaciers are facing.

Forget drinking countless glasses of water or getting your beauty sleep.The secret of looking young is simply to stay out of the sun.
A study of hundreds of women has revealed that those who avoided the sun’s rays looked up to 20 years younger than they actually are. However, other supposed rules for a youthful complexion, from drinking lots of water to sleeping well and exercising regularly, failed to hold back the hands of time.
Only keeping out of the sun, and wearing sunscreen when this wasn’t possible, made a difference, the American Academy of Dermatology’s annual conference will hear today.
The finding comes from a study of 231 women of all ages who were quizzed about their lives, including whether they were sun-loves. When researchers from Massachusetts General Hospital in the US guessed how old the women were, they found those who took care in the sun tended to have aged more slowly.
Four lucky women had so few wrinkles and age spots and such a glowing complexion,that they appeared to be twenty years younger than they really were.
Researcher Dr.Alexa Kimball said the popular belief that we drink lots of water to stay healthy is false and the body is “pretty good” at judging how much we need.Previous research by the British Nutrition Foundation reached a similar conclusion.
It isn’t clear why the women who slept well didn’t have younger-looking skin.But it may be that the question they were asked was too narrow and didn’t consider their long-term sleep patterns.
1.Which way can help women stay younger according to the study?
A. Having a good sleep. B. Drinking plenty of water.
C. Taking exercise regularly. D. Keeping out of the sun.
2.How did the researchers know the finding about women of all ages?
A. Through calls. B. Through games.
C. By quizzes. D. By interviewing face to face.
3.What’s the main purpose of the passage?
A. To introduce a good way to make women look younger.
B. To explain how scientists carried out the research.
C. To prove people’s previous ideas are true.
D. To persuade women to change their long-term sleep patterns.
4.This passage is most probably taken from______________.
A. a school textbook. B. a science fiction.
C. a reference book. D. a science paper.

Cold weather can be hard on pets, just like it can be hard on people. Sometimes owners forget that their cats are just as used to the warm shelter (住所) as they are. Some owners will leave their animals outside for a long period of time, thinking that all animals are used to living outdoors. This can put their pets in danger of serious illness. There are things you can do to keep your animal warm and safe.
Keep your pets inside as much as you can when the weather is bad. If you have to take them out, stay outside with them. When you’re cold enough to go inside, they probably are too. If you must leave them outside for a long time, make sure they have a warm, solid shelter against the wind, thick bedding, and plenty of non-frozen water.
If left alone outside, dogs and cats can be very smart in their search for warm shelter. They can dig into snow banks or hide somewhere. Watch them closely when they are left outdoors, and provide them with shelter of good quality. Keep an eye on your pet’s water. Sometimes owners don’t realize that a water bowl has frozen and their pet can’t get anything to drink. Animals that don’t have clean and unfrozen water may drink dirty water outside, which may contain something unhealthy for them.
1.What do we learn about pets from Paragraph 1?
A.They are often forgotten by their owners. B.They are used to living outdoors.
C.They build their own shelters. D.They like to stay in warm places.
2.Why are pet owners asked to stay with their pets when they are out in cold weather?
A.To know when to bring them inside. B.To keep them from eating bad food.
C.To help them find shelters. D.To keep them company.
3.If pets are left on their own outdoors in cold weather, they may .
A.be short of clean water B.dig deep holes for fun

You’ve heard it repeatedly: Make sure you drink at least eight glasses of water per day. The key words are "at least", because, unless you are a child, you need more water than that. The rule is, for every 50 pounds of body weight you carry, drink one quart of bottled or filtered (过滤的) water per day. The average person weighs 150 pounds, so they should drink three quarts per day. A 200 pounds person should drink a full gallon per day. Athletes should drink even more than that. Follow these and you’ve adopted one of the most important health habits.
Our bodies are mostly water, and water is essential to our every function. Drink the appropriate amount, and everything is much more likely to function at the best levels. If you don’t drink enough water, over the short term you will experience tiredness, dry skin, headaches and constipation (便秘); over the longer term, every body function will degrade more quickly. It really is as simple as that.
Things get a bit more complicated in what type of water to drink. Bottled water and filtered water are both good options. Do not drink tap water or distilled water (蒸馏水).Bottled water should be bottled in clear glass containers, not the plastic containers that transfer far too many chemicals into the water. Filtered water can be obtained through low-cost filters.
Tap water should be avoided because it contains chlorine (氯) and may contain fluoride (氟化物), which is poisonous and can have terrible consequences for the body. Distilled water should also be avoided because it can burn up your body of necessary minerals. It has been tied to hair loss, which is often associated with certain mineral lack.
Finally, drink water at room temperature if possible, as ice-cold water can harm your stomach.
1.What’s the meaning of the underlined word “degrade”?
A. Improve. B. Reduce.
C. Strengthen D. Recover.
2.What kinds of water are proper for drinking?
A. Tap water and bottled water.
B. Tap water and distilled water.
C. Bottled water and filtered water.
D. Distilled water and filtered water.
3.What’s the main reason that distilled water isn’t recommended to drink?
A. It leads the body to lack certain minerals.
B. It isn’t clean enough to drink.
C. It contains too many chemicals.
D. It contains fluoride.
4.Which of the following statements is NOT true according to the passage?
A. It is harmful to drink plenty of icy water.
B. One may feel tired due to lack of water for a short time.
C. The water with chlorine is not suitable to drink.
D. The water in plastic containers is safe to drink.

Bend over, take a deep breath and drink some water! This is just one of the hundreds of tips you might get if you have the hiccups(打嗝). Hiccups are so mysterious. We really don’t know why they start and why they stop.
Everyone has a favorite cure for a case of the hiccups. Some people think that a good scare is necessary to get well. Others eat a teaspoon of sugar. Still others drink a glass of water with a knife in it.

It took a British plumber eight months to cure his hiccups. People from all over the world wrote him letters with suggestions for getting well. He tried them all, but the hiccups continued. Finally, he drank a “secret’’mixture someone had sent him. By that evening his hiccups were gone. Why did these cures work for these two men? No one really knows.

Here are five cooking habits that could be costing you important nutrients, causing you to overeat——or even making you sick.
Boiling vegetables
A 2015 review showed that boiling vegetables resulted in a high loss of vitamin C. 1. "If you're not drinking a soup, you're missing out on nutrients," says Nishta Saxena, a dietitian based in Toronto .
Washing chicken
While your favourite old cookbooks likely tell you to wash a chicken before cooking, this outdated advice is a safety risk. Cleaning meat in water may remove some of the bacteria, but it's also likely to pass it around your kitchen. 2. And clean your hands after you've finished the cooking.
Removing skins from fruits and vegetables
"Large amounts of nutrients are found in the skins." says Liz Powell, who is a dietitian from Vancouver. " Concern about chemical remains isn't a good enough reason to do the removing. 3."
Mixing everything
A smoothie (a mixed drink) is a smart way to eat some greens. 4. They're often short of protein and healthy fat. These things work together to keep us feeling full and satisfied. Without them, it's not really a balanced meal, Powell suggests adding some foods which contain protein or having a piece of wholewheat(全麦的)bread on the side.
Overdressing salads
We think we can add anything to salads, and they'll still be a nutritious choice. But it's just not true. If you're topping your bowl with dried strawberries and sweet cheese, you've easily added 30 grams of sugar to your so-called healthy lunch. 5.
A.You should choose healthy produce for your family.
B.But these kinds of drinks are likely to be unbalanced.
C.To stay safe, don't wash the meat when preparing it.
D.Cabbage. for example, loses about 33 % of its vitamin C.
E.Nuts are better choices to improve the taste of your greens.
F.The skins of potatoes contain more nutrients than its inside part.
G.Washing your produce will remove some chemicals from the surface.

Two European Summer Must “Seas”
When you think of summer, the beach, clear water, sunny skies, and relaxing days are a few things that come to mind, and two of the best places to experience these summer feels are two gorgeous European bodies of water: the Mediterranean Sea and the Adriatic Sea! These two incredible Seas hold some of my favorite travel memories, and I would revisit each one in a heartbeat!
The Mediterranean Sea
The Mediterranean Sea can be accessed from various European countries as well as a few North African countries. And while many think of visiting Ibiza, Malta, or the Greek islands to experience the Mediterranean, my Mediterranean beach days came while visiting the seaside city of Marseille in the South of France! Marseille was a lovely city with easy access to the Sea, also with pretty sandy beaches. The gorgeous crystal clear blue water made it unlike any beach day in America! Not only were the beaches amazing, but the city of Marseille was adorable and filled with numerous cute shops and seaside restaurants. And the Mediterraneanstyle food was delicious!
The Adriatic Sea
The Adriatic Sea is equally as stunning and surely worth a visit! The Croatian coast has numerous beach clubs, some private and some public, that tourists are able to visit and you can experience the beauty of the Adriatic Sea there! Zrce Novalja, a Croatian seaside town I visited, was impressively featured by the rather rocky beach in place of sand. The rocks were small and smooth, making swimming in the sea and wading in the water just as easy as sandy beaches! Plus, the locals in Croatia are also extremely friendly, making the experience even more memorable.
1.The writer's trip to the two seas was full of ________.
A.unbearable hardships B.various adventures
C.wonderful experiences D.funny events
2.From which place did the writer get to the Mediterranean Sea?
A.Ibiza. B.Malta.
C.The Greek islands. D.Marseille.
3.What makes Zrce Novalja so special?
A.Its beach clubs. B.Its beautiful sea.
C.Its rocky beach. D.Its friendly locals.

It's the most popular drink worldwide. According to the British Coffee Association, approximately two billion cups of coffee are consumed every day. But after the beans have been picked, roasted and brewed, the grounds(渣子)are often treated as waste. With the environment and resource consumption such hot topics at the moment, wouldn't it be great if we could reuse this waste to make something useful?
The company OCHIS produces sunglasses. Max Havrylenko, founder of the company, was searching for an alternative material to plastic. He wanted to "solve the problem of plastic use and overconsumption so as to create a greener world," he told the Guardian. OCHIS heats the grounds with vegetable oils, forming a bond. These are pressed into plates which are durable and flexible. These are then cut into the arms and frames of the glasses. "Don't worry," he says, "They won't dissolve(溶解)in the rain."
Rosalie McMillan, a London jeweler, uses recycled coffee grounds along with gold and silver to make handcrafted jewelry. Mixed with oils, the coffee is then subjected to heat and pressure to create a compound she calls "Curface". Her website says it has a "beautiful surface quality and texture" with similar properties to hardwood.
What about a coffee cup made from them? Kaffeeform is a German-based company that transforms used grounds and renewable plant-based raw materials into a durable composite. This is shaped into a variety of containers and polished and finished, ready to be sold. So, you can drink your coffee from a cup made of coffee.
And it doesn't stop there. Even without a factory, you can make use of coffee grounds. They make excel-lent fertilizer(肥料). You can highlight something against them, or mix them with water to make a brown-toned paint. And the list goes on. So next time you finish your morning cup, lake a while to think again.
1.The first paragraph is mainly written to introduce .
A.how people treat coffee grounds B.annual consumption of coffee
C.growing popularity of coffee D.the big problem of wasting food
2.What can be inferred from the second paragraph?
A.OCHIS doesn't make sunglasses at all at present.
B.Plastic might be less eco-friendly to environment.
C.Coffee has become the raw materials of sunglasses.
D.Coffee-based plates are more durable and flexible.
3.The underlined word "subjected" in Paragraph 3 can be best replaced by .
A.accustomed B.exposed C.relevant D.sensitive
4.What does the author advise people to do in the last paragraph?
A.Think about how to recycle the coffee grounds. B.Take full advantage of their time.
C.Add more information to the list. D.Keep away from the coffee cups.
