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 2­liter 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.

1. You should drink enough water every day because________.

A．your body needs too much water

B．water does all kinds of jobs in your body

C．your body loses a lot of water every day

D．the more water you drink the better you feel

2. Water in your body loses by the following ways EXCEPT________.

A．breathing　     B．evaporating

C．sweating　     D．eating

3. Your body has to give enough water to your skin in order to________.

A．keep the water in your skin clean

B．stop your skin from drying out

C．stop the water from losing

D．keep your skin clean all the time

4. What does the underlined phrase “rely on” in the fourth paragraph mean?

A．Eat up.　     B．Receive.

Love the way you walk

Listen carefully to the footsteps in the family home, and you can probably work out who is walking about. The features most commonly used to identify people are faces, voices and fingerprints. But the way they walk is also a giveaway.

Researchers have used video cameras and computers to analyze people’s gaits, and are now quite good at it. But translating such knowledge into a practical identification system can be tricky. Cameras are often visible, are difficult to set up, require good lighting and may have their view blocked by other people. A team led by Dr. Ozanyan and Dr. Scully have been looking for a better way to recognize gait. Their answer: pressure-sensitive mats.

Such mats are nothing new. They have been part of security systems. But Ozanyan and Scully use a complicated version that can record the amount of pressure applied in different places as someone walks across it. These measurements form a pattern unique to the walker. The researchers turned to an artificial-intelligence system to recognize such patterns, and it seemed to work. In a study in 2018, they tested the system on a database of footsteps of 127 people. They found its error rate in identifying who was who was a mere 0.7%. And Scully says even without a database of footsteps to work with, the system can determine someone’s sex and, with reasonable accuracy, a subject’s age.

One application of the mat-based gait-recognition system might be in health care, particularly for the elderly. A mat placed in a nursing home or an old person’s own residence could monitor changes in an individual’s gait that indicates certain illnesses. That would provide early warning of someone being at greater risk of falling over.

Gait analysis might also be used as a security measure in the workplace, monitoring access to restricted areas, such as parts of military bases, server farms or laboratories dealing with dangerous materials.

Perhaps the most interesting use of the mats, though, would be in public places, such as airports. For that to work, the footsteps of those to be recognized would need to have been stored in a database, which would be harder to arrange than the collection of photographs and fingerprints that existing airport security systems rely on. Many aircrew or preregistered frequent flyers would welcome anything that speeded up one of the most tiresome parts of modern travel.

1.What is mainly talked about in Paragraph 2?

A.Research equipment. B.Research findings.

C.Research assumption. D.Research background.

2.According to Paragraph 3, the mat is used to _______.

A.collect data B.ensure safety

C.determine age D.analyse pressure

3.The gait-recognition system might be applied to _____.

A.monitor security work progress B.detect potential health problems

C.keep track of travelling frequency D.warn passengers of possible dangers

4.The main purpose of the passage is to _____.

A.compare and educate B.examine and assess

C.discuss and persuade D.explain and inform

We know that sometimes studying a new language can be hard work but it can be fun too--and if we can make our learning experience fun, then we will learn better. So here are some more of our top tips for making studying fun.

Firstly,1.--make sure your chair is suitable and it’s at the right height for the desk. Make sure you have good ventilation(空气流通) and light and the space you’re in isn’t too hot--you don’t want to fall asleep! And put away anything that might distract you, like your smartphone.

Rather than just staring at books and being passive,2.. Why not record yourself and listen back to yourself speaking or reading out information. Or you could turn facts into songs and sing them out loud--this is sure to make information stick in your head!

3.--flashcards are very useful because they provide visual clues that help you remember things. You could also stick words, grammar rules and other bits of information on notes around your study space or other places around your house--so for example, you can read them when brushing your teeth!

Don’t feel daunted by the amount of studying you have to do.4.. Study in small bursts and vary the topics you study so you don’t get bored and you stop retaining information. If you can, choose a time of day that best suits your natural preference. Some people work best at night while others work best early in the morning.

Finally, don’t overdo it--know your limits--if you study too hard it won’t be fun and you won’t absorb information.5.--and give yourself a small reward when you do.

A. try to become an active learner

B. So care your mental and physical health

C. get comfortable

D. So take regular breaks

E. Also be creative

F. And don’t try to study continuously all day to fit it all in

G. But you can focus on some entertainments

Do you enjoy seeing the stars twinkling at night ? Or do you love the ocean and sea, diving and racing with lovely dolphins? With heavy burdens on their shoulders, teenagers find it hard to pull out. Even if they are free, they prefer to occupy themselves with computer games or watching TV. How to get children away from screens is a great concern for parents. Now there is some good news for those concerned parents and teachers.

A campaign is being launched to encourage children to surrender 30 minutes of screen time a day to head for the great outdoors.

The newly formed Wild Network – a collaboration of nearly 400 organizations – is attempting to attract youngsters away from television and computer screen and into fields, woods and parks.

Organizers say it is the UK's biggest ever campaign to reconnect children with nature and outdoor play, and claim it could help improve fitness, mental alertness and general well–being.

A documentary film, Project Wild Thing, will herald the launch at more than 50 cinemas across the UK from Friday. It looks at the increasingly fragile link between children and nature.

Members of the network include the National Trust, RSPB, Play England and the NHS sustainable development unit.

Andy Simpson, chairman of the Wild Network, said: "The tragic truth is that kids have lost touch with nature and the outdoors in just one generation. Time spent outdoors is down, roaming ranges have fallen drastically, activity levels are declining and the ability to identify common species has been lost."

Suggestions of how to get more time in nature include collecting conkers(板栗), camping or snail racing, and observing autumn colour on trees.

From January, the network will aim to make suggestions to politicians on how government can do more to get children muddy and bright-eyed.

This is not the first time the message of less screen, more play has been brought up. Children in the 1980s were entreated to do the same by the BBC TV series Why Don't You, which somewhat confusingly called on its viewers to "switch off your TV set, and go do something less boring instead".

1.What is the main purpose of the campaign in UK?

A. To save 30 minutes for watching TV programme each day.

B. To encourage children to play outdoors.

C. To see the documentary film, Project Wild Thing.

D. To teach students how to learn more efficiently in schools.

2.According to the organizers of Wild Network, there will be many advantages from the campaign except _______.

A. improving health conditions

B. keeping touch with nature

C. learning more about wildlife

D. teaching children how to make full use of their spare time

3.The underlined part “ to get children muddy and bright-eyed ” means “_______ ”.

A. to make children covered with mud

B. to urge politicians to do more things for children

C. to encourage children to take part in outdoors activities

D. to help children identify common species

4.Which of the following could be the best title for the passage?

A. A new campaign.                                                          B. Less screen, more play outdoors.

C. A newly formed Wild Network.                                 D. Children get to know wild things.
