In today's world English has become a global language. Speaking or writing in English is a matter of global interest these days, for it is now a requirement for being able to communicate with the outer world. {#blank#}1{#/blank#}.

    Enthusiasm（热情）

    The first thing you need to have is an enthusiasm to reach your goal. The most important thing you have to have is emotional devotion（情感，承诺）with your desire to learn English quickly. {#blank#}2{#/blank#}.

    {#blank#}3{#/blank#}

    You pass by a lot of things in English that you meet with in your day-to-day life. Things could include magazines, emails, posts on social media, websites, a piece of literary work（文学作品）or a newspaper. Read them because you never know what is waiting for you in there. You might find that a lot of things are already known to you but the content will surely be full of new vocabulary allowing you to improve faster.

    Keep a note of the new words

    {#blank#}4{#/blank#}. It's a bit more important that you keep a handy notebook with you and whenever you learn a new word or expression, write down the context along with the word. Use the word in a sentence and note the meaning, too. Sometimes you may find forgetting a certain word or phrase seems impossible. {#blank#}5{#/blank#}. So, to prevent this you need to keep visiting your pages and go through the notes you have made time and time again.

A. Don't just move on after reading

B. Read everything you may come across

C. Don't let yourself down if you face a difficulty

D. However, being a human being you are built to forget

E. You won't achieve success if you aren't enthusiastic enough

F. By following these tips you will improve the language quickly

G. Spend the most of your time in either listening or reading in English

    Long ago, people believed that in the future we would work less, have more free time and get more relaxed. {#blank#}1{#/blank#}

    Today we work harder, work longer hours and have more stresses than ten years ago. We walk faster, talk faster and sleep less than previous generations. And although we use machines that save us time, we have less free time than our parents and grandparents. {#blank#}2{#/blank#} An American journalist James Gleick in a new book, says that people are suffering from "hurry sickness" — we're trying to do more things in less time. As a result, our lives are stressful. He says that if we don't slow down, we won't live as long as our parents. {#blank#}3{#/blank#}

Newspaper articles today are shorter and the headlines are bigger. Most people don't have enough time to read the articles, so they only read the headlines. On TV and the radio, newspapers speak more quickly than ten years ago. In the USA, there is a book called One-Minute Bedtime Stories for children. These are shorter versions of traditional stories, specially written for "busy parents" who want to save time! Some answer phones now have "quick playback" buttons so that we can replay people's messages faster— we can't waste time listening to people speaking at the normal speed! {#blank#}4{#/blank#} Ten years ago when people went to art galleries they spent seconds looking at each picture. Today they spend just three seconds! Nowadays, many people prefer faster and dynamic sports like basketball.

    {#blank#}5{#/blank#} Our cars are faster but the traffic is worse, so we drive more slowly. We spend more time sitting in our cars, feeling stressed. Experts predict that in ten years the average speed on the road in cities will be only 17 km/h.

A.People didn't feel stressed ten years ago.

B.But unluckily, this has not happened yet.

C.Even when we relax we do everything more quickly.

D.But what is this doing to our health?

E.For most people, being faster doesn't mean being better.

F.The only thing that is slower than before is the way we drive.

G.Now everything is faster than before, which bring us more convenience.

    Do you know that there's a new frontier in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. {#blank#}1{#/blank#}

    Food production

    With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. {#blank#}2{#/blank#} —it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to "re-create forms and pieces" of food that are "exactly the same," freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.

    Sustainability

    According to a new study, the global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. {#blank#}3{#/blank#} 3D food printing could probably contribute to the solution. 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.

Nutrition

    {#blank#}4{#/blank#} Hod Lipson, a professor at Columbia University, said, "Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday's bread from the supermarket, you'd eat something baked just for you on demand."

    {#blank#}5{#/blank#}

    Despite recent advancements in 3D food printing, the industry has many difficulties to overcome. Currently, most ingredients must be changed to a paste(糊状物) before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad.

A. Challenges

B. Opportunities

C. And the industry isn't stopping there.

D. Sustainability is becoming a necessity.

E. Future 3D food printers could make processed food healthier.

F. Here are some new ways to produce 3D printing.

G. Not everybody can do that.

    I didn't just read a book in print, on an e-reader or even on a mobile phone. Instead, I read a book on dozens of devices. I was not trying to set a Guinness World Record. I wanted to answer a question I often hear: {#blank#}1{#/blank#}? So I set out to try them all, reading a chapter on each: the Amazon Kindle, the first and second generation Apple iPads and mobile phones. To be fair, I also read a chapter in that old-fashioned; form—a print book.

    The book I chose was The Alienist. For the first chapter, I turned to an Amazon Kindle. {#blank#}2{#/blank#}. The kinder is light. Its six-inch screen is the perfect size for reading, and reading on its black-and-white-E-Ink display doesn't harm your eyes. {#blank#}3{#/blank#}, and on average you charge the device only once a month. My only complaint with the Kindle design was the placement of the keyboard at the bottom of the device.

    Despite the small screen on a mobile phone, I found reading on one to be simple and satisfactory. {#blank#}4{#/blank#}, but all of the phones on which I read chapters felt somewhat similar.

    If I had wanted to, I could have bought my book through dozens of e-book apps in the Apple App Store. Most are free and offer access to thousands of free e-books or paid versions. Both iPads 1&2 offer an immersive(身临其境的)reading experience. I found myself jumping back and forth between my book and the web, looking up old facts and pictures of New York City. {#blank#}5{#/blank#}.

    For the last chapters of the book, I read the print one, which is still my favourite choice.

    Since we are comparing devices. So I guess I need to choose one. In the end it might come down to Kindle. But if money is tight, go for print. My used print book cost only $4 from Amazon.

A. Battery life is outstanding

B. Which e-reader is the best for reading books

C. Shopping on Amazon for the Kindle is simple

D. Should students make use of the devices to read

E. No wonder a lot of readers also speak highly of it

F. Reading on the Amazon Kindle is a joy in many aspects

G. The brightness and size of the mobile phone's screen did vary

    Please wear loose clothing, mostly cotton. It is obvious that wearing clothing that is loose rather than tight is welcomed in summer. {#blank#}1{#/blank#}. This carries away the warmth that your body produces and allows cooler air to flow back in.

    {#blank#}2{#/blank#}. When it's really hot out, materials that “breathe” — allowing the flow of air through the fabric (衣料) itself — also work to keep you cool. Cotton and linen are among the most breathable fabrics，so look for clothes made of those substances.

    Your body controls its temperature via a small peanut-shaped section of the brain known as the hypothalamus (下丘脑). {#blank#}3{#/blank#}. It turns the temperature up or down based on various factors — such as how cold or hot the skin is.

    Certain parts of the skin have a larger influence than others. {#blank#}4{#/blank#}. They get their name because you can feel your pulse there, and the reason you can do that is because vessels are so close to the edge of your skin that one can easily hear or feel the flow of blood.

    When you want to lower your body temperature, cooling those pulse points with cold water or ice sends a signal to the brain that says, “Turn cold.” {#blank#}5{#/blank#}. Focus on pulse points that are easy to reach: the insides of your wrists, the area around your temple, and your neck. Holding an ice pack or even a cold washcloth against the skin on these regions will make your entire body feel cooler.

A. It allows air to flow past the skin

B. Sweating helps to cool off the skin

C. These areas are called pulse points (脉冲点)

D. The type of fabric you wear has an influence, too

E. This fools your brain into turning down its thermostat (恒温器)

F. This region works almost like a thermostat in a home

G. Exercising in extreme heat is usually not recommended

    Many students have trouble staying focused in class. Some of them easily become absent-minded or fall asleep. As a result, they turn to study drugs in order to stay focused in school. {#blank#}1{#/blank#}

    Get some sleep.

    {#blank#}2{#/blank#} And it is important to stick with it. Having irregular sleep cycles can really affect concentration and physical well-being. Try to go to sleep at the same time every night and get eight to nine hours of sleep. Your body will thank you in the morning.

    {#blank#}3{#/blank#}

    Eating first thing in the morning provides fresh energy throughout the day, and it doesn't even have to be a big meal. Something as small as a bowl of oatmeal can make students more energetic and efficient for the rest of the day. And foods like peanut butter, berries, and whole grains have even shown to improve memory.

    Turn off your phone.

    An obvious way to maintain concentration is to avoid distractions that take your attention away.

    {#blank#}4{#/blank#} When students need to channel their energy into studies, turning off the phone or even putting it on airplane mode is a good way to centralize their drive and keep distractions at bay.

    Break a sweat.

    Trying to concentrate in class will feel as challenging as a marathon if you're not in good physical health. On the other hand, actually running a marathon may help boost your ability to concentrate, as exercise is shown to have many benefits for the brain. While you don't necessarily have to run 26 miles before class or work, doing exercise in the morning can get your blood flowing towards your brain. {#blank#}5{#/blank#}

A. Do not skip breakfast.

B. Sit in the front if you sleep in class.

C. That helps in strengthening the mind.

D. Probably the biggest one is the smart phone.

E. Students should have a regular bedtime routine.

F. But many study drugs have proven harmful to human health.

G. However, there are other all-natural ways to help with concentration in class.
