阅读理解

    Water is important in our daily life. When you are thirsty, you might want to drink water. However, a new study has found that drinking water is not the best way to stay hydrated (补水的).

    Water does a good job of hydrating the body quickly, according to British researchers. However, drinks with a little bit of sugar, fat or protein (蛋白质) can do a better job.

    Why is that? The more you drink, the faster the drink leaves your stomach and goes into your bloodstream. There, it can dilute (稀释) the body's fluids (液体) and keep you hydrated. Milk, for example, has some sugar, protein and fat. These make fluids leave your stomach more slowly and keep you hydrated for a longer time.

    However, drinks with more sugar, such as fruit juice or soda, are not more hydrating. When these drinks go into the small intestine (小肠), they take more water from the body into the small intestine to help deal with the sugar. This will make you feel even thirstier.

Which drinks hydrate us the most?

No. 1: Milk

It's more hydrating than water or other drinks.

No. 2: Water and coffee

A cup of coffee is about as hydrating as a cup of water. However, drinking two to four cups of coffee will make you thirstier. You can put one or two spoonfuls of milk in your coffee to keep you hydrated.

No. 3 Fruit, Juice and soda

If you have to choose between these drinks and water, always go with water.

(1)、Which of these drinks can hydrate you the most?
A、Milk. B、Water. C、Soda. D、Fruit juice.
(2)、Why can't sugary drinks keep you hydrated?
A、Because these drinks can't go into your bloodstream. B、Because these drinks leave the stomach quickly. C、Because it takes more water to deal with the sugar. D、Because the small intestine can't dilute these fluids.
(3)、How does water keep you hydrated?

a. Water goes into the bloodstream.

b. Water enters your stomach.

c. They body is hydrated.

d. Water leaves the stomach.

e. The body's fluids get more water.

Answer the questions (根据短文内容回答下列问题)

   In thetime it takes you to read this sentence, the population of the Earth will have grownby 10 people. That may not sound much, but it is about 14,000 people an hour. Thatis the same as adding most of the population of Germany to the world every year!

   Most of these new people are born in developing countries. These countriesare found in much of Africa, South America, and parts of Asia. In the developedcountries of Europe and North America, the population is growing very slowly. Thisis because women in these countries have, on average, only one or two children.In the developing countries, many women have five or more children. In 1950, aroundone quarter of the world's population lived in the developed countries. By 2050,these countries will be the home to only around one tenth of the world's people.

   In the developing countries, more than one billion people already live belowthe poverty line (贫困线).These people don't have enough food to eat and they live in poor housing;children get little or no time at school and suffer from many kinds of diseases.

   The United Nations (UN) tries to guess population growth. At the beginningof the 21st century, the world's population was around six billion people. The UNhas said that the world's population will level off at 12. 5 billion people by theyear 2100. Other people think the world's population will continue to grow, reaching14 billion people before it becomes stable or even falls.

 阅读下列短文,从下面每小题所给的A、B、C、D四个选项中, 选出最佳选项。

 When you think of the sea, you may not think of Xinjiang or Inner Mongolia. But recently, the" seafood" produced in these places has become popular, especially after Japan put muclear- contaminated water(核污染水) into the sea, reported China Daily.

 In Nilka county(尼勒克县) in Xinjiang, about 6,000 tons of rainbow trout(虹鳟鱼) will be produced this year. Rainbow trout belongs to the same family as salmon(鲑鱼), which is a kind of well- known seafood. It tastes like salmon too.

 Why do farmers there choose to grow fish? The weather in some parts of Xinjiang is seldom hot, and the rivers are fed by meltwater(融水) from the Tianshan Mountains. Water deeper than 6 meters always stays at 10 C. As the meltwater is very clean and cold, it's a" comfortable" home for fish, Li Chunyu, a worker at a fish company in Xinjiang, told China Daily.

 To make sure the river stays clean, the company uses machines to clean fish waste in the water. They also use net cages(网箱) that are good for the environment. The net s are about 51 meters wide and lie 25 meters deep in the river.

 Meanwhile, in Inner Mongolia, whitele g shrimp(南美白对虾) grows well. Saline soil(盐碱土) covers a large part of the desert where few plants are able to grow. Farmers used to put water from the Yellow River onto the farmland to wash away the salt. This was a waste of salty water.

 Scientists then decided to create" seawater" with the salty water by adding in some other components. Whiteleg shrimps can live well in this kind of water. They taste no different from the same kind of shrimp that grows in the sea.

Ways to increase confidence

 Self-confidence is important for everyone's success. If you don't have confidence, it becomes very hard to move forward and make progress in life. With this in mind, here are some tips to increase confidence. 

{#blank#}1{#/blank#}

 One thing that's easy to do is to change your appearance. It's amazing how good a new dress, a haircut, or having your teeth whitened or your nails done can make you feel. Even a humble shower and a shave can give your self-image a lift. Looking confident will help you feel more confident. 

{#blank#}2{#/blank#}

 Leave behind the ones who put you down. If that's not possible, see them less. A survey of  48 studies by the American Psychological Association in 2019 found positive(积极的) social relationships improved self-confidence but poor-quality relationships had a bad effect. Actively meet them, as having fun with great people will make you feel better about yourself. 

{#blank#}3{#/blank#}

 Getting out of your comfort zone will give you a sense of achievement and help yourself-belief. When you try new things and accept new challenges, you will be surprised to find there will be dreams. Would you like to paint better? Look around for an art class. You'll will boost your self-confidence and get to meet like-minded people at the same time. 

{#blank#}4{#/blank#}

 Research has shown that getting out into a green space can increase self-confidence. Meanwhile, Canadian research found that joining some groups benefited self-confidence more than having lots of friends. So why not kill two birds with one stone and sign up for a walking group, a local conservation group or a gardening club?

A. Try something new

B. Give yourself a new look

C. Make plans with positive people

D. Join lots of outdoor groups

E. Cheer yourself up

Please give one more way of increasing confidence and list at least two reasons. {#blank#}5{#/blank#}

 根据材料内容, 选择最佳答案

①Which is more important in your mind, looking fashionable or feeling comfortable? You may find many people choose style over comfort and some even go to extremes(极端) to follow fashion. But we should remember: being fashionable isn't everything. It's more important to be healthy.

②Some people believe that they need to be a certain size to look good. So, they start extreme diets that are not good for their health. They might not eat meals or eat too little, which can make them feel sick. Is it a healthy way to live?

③Also, many girls wear shoes with very high heels. They might think high heels make them look taller. But, these shoes can actually hurt their feet and make it hard to walk comfortably, and they can increase the risks of falls. Some even wear tight clothes that influence blood circulation(循环), making it hard to breathe. Should we put fashion over comfort and physical health?

④Besides, some boys and girls spend a lot of time and money changing their hair color. The material they use is usually harmful to their health. To make their hair straight or curly, they also use tools that are hot enough to burn their hair. But using these tools too often or . at very high temperatures can make the hair dry or even burnt. Is it really worth it to risk our health, spending so much time and money?

⑤So, let's think again what's really important. Is it fashion or is it our well-being? Clothes or hairstyles don't tell us anything about a person's character. Instead of spending a lot of time choosing clothes, we could use that time to do fun things with friends. And instead of following extreme diets, let's eat properly and exercise regularly. Remember, the value of you is not. decided by your appearance, but by who you are as a person.
