Is It Bad to Cross Your Legs When You Sit?

Crossing your legs is an extremely common habit; most people don’t even notice that they’re doing it when they sit down. W hile you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.

A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason this happens is because the blood in your legs has to work against gravity to be pumped back to your heart, crossing one leg over the other increases resistance, making it even harder for the blood to circulate. This causes your body to increase your blood pressure to push the blood back to the heart. You won’t feel any immediate effects, but if you sit for long periods of time it’s important that you take note of how long you have your legs crossed for. You shouldn’t have your legs crossed for more than 15 minutes, and it’s important that you get up and walk around at least once every hour.

Crossing your legs can also lead to neck and back pain. Ideally, it’s best for our bodies to sit with our feet planted flat, hip width apart, on the floor, but it’s not easy to maintain perfect posture all day at the office. When you sit with your legs crossed your hips are in a twisted position, which can cause one of your pelvic bones to rotate. Since your pelvic bone supports your neck and spine, this can cause pressure on your lower and middle back and neck.

You also might notice that when you sit with your legs crossed for long periods of time your feet and legs get tingly or have the feeling of being asleep. This is because when one leg sits on top of the other it causes pressure on the veins and nerves in your legs and feet. It can cause numbness and/or temporary paralysis in the legs, ankles, or feet. While the feeling of discomfort may only last a minute

or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.

So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.

A.it’s no big deal to cross our legs for less than 15 minutes.

Microsoft has developed a new smartphone app that interprets eye signals and translates them into letters, allowing people with motor neurone disease to communicate with others from a phone.

The GazeSpeak app combines a smartphone’s camera with artificial intelligence to recognize eye movements in real time and convert them into letters, words and sentences.

For people suffering from ALS（渐冻症）, also known as motor neurone disease, eye movement can be the only way they are able to communicate.

“Current eye-tracking input systems for people with ALS or other motor impairments are expensive, not stable under sunlight, and require frequent re-calibration and substantial, relatively immobile setups,” said Xiaoyi Zhang, a

researcher at Microsoft who developed the technology.

“To ease the drawbacks…we created GazeSpeak, an eye-gesture communication system that runs on a smartphone, and is designed to be low-cost, stable, portable and easy to learn.”

The app is used by the listener by pointing their smartphone at the speaker. A chart that can be stuck to the back of the smartphone is then used by the speaker to determine which eye movements to make in order to communicate.

The sticker shows four grids(网格) of letters, which each correspond to a different eye movement. By looking up, down, left or right, the speaker selects which grids(网格) 24the letters they want belong to. The artificial intelligence algorithm is then able to predict the word or sentence they are trying to say.

Zhang’s research, Smartphone-Based Gaze Gesture Communication for People with Motor Disabilities, is set to be presented at the Conference on Human Factors in Computing Systems in May.

3.Which of the following is the correct order of how the app works?

a.The sticker puts forward four grids of letter.

b.The listerner points the phone at the speaker

c.The speaker uses a chart to determine which eye movement to make.

d.The users use their eye movements to select the grids of letters they want to

choose.

A.bacd

B. bcad

C. bdca

D. Bcda

4.Which of the following is not the advantage of Gazespeak?

A.Unsteady

B. Easy to take

C. Easy to learn

D. Inexpensive

5.Which can be the best title of this text?

A.A Helpful Communicator For ALS

B.Smartphone App Helps ALS Sufferers Speak With Their Eyes

C.The Greatest communicative App For ALS

D.Smartphone--based Gaze Gesture communication

How to Enjoy Life As a Teen

The "best years of your life"? Maybe not, but you can learn to make the most of your high school days.

1. Learn to appreciate small things. Whether it's having a computer, having friends, having a good supply of food, a bed to sleep on, family that loves you, having a decent education or simply being born in this world. 6 . Be happy, and life will reward you. Remember that these are the last few years you will be able to enjoy yourself without having to worry about the responsibility of an adult, but make sure you prepare yourself for when you do become one.

2. Go for it! If you have a special girl/guy you want to ask out, dance with, etc. just ask! You probably won't be rejected but if you are, remember that there will always be someone else that likes you for who you are. 7 . About 90% of the girls or guys you talk to will like you back, only about 10% probably will reject or badmouth you.

3. 8 . There is nothing more satisfying than seeing your hard work pay off in the form of A's and B's (but mainly A's). This also sets you up to get into a college you want to go to, which in turn prepares you for a career you will enjoy, improving your quality of life in the future. You'll get cheap car insurance as well if you have at least a B or A average.

4. You can pursue interests you enjoy. Video games, for example, are good if you're the type who can get into that kind of thing. 9 . Use your "hobby time" to either A) Volunteer (to gain practical skills for college apps, job resumes, and scholarships) B. Learn an instrument, or get into something else in the creative field like painting or dance, because this is the time to start developing and uncovering passions that might otherwise lie dormant.

5. Work at a job you can enjoy. Working is a great way to gain experience and to meet other people. When you do get out of college, interviewing companies will look at your prior work experience. This will look great on your resume. If you can't find work, especially in this hard economic time, volunteer or make your own job.

6. 10 You'll still be going to games for free like the jocks if you are in pep band, and you have as many opportunities to meet new people as the jocks. Band and choir sometimes involves going on trips, and are great memories to have for high school and college. If you are not good at either music or sports, you can join other activities, start other hobbies, or get a job.

A.You should also find a hobby that is meaningful or practical.

B.Participating in clubs, activities, and sports increases your chances of meeting new friends.

C.Choose your friends wisely.

D.Don't go to sleep that night wishing you would have asked them.

E.Remember that the point of life is for you to enjoy it.

F.Keep your grades up

G.If you are not good at sports, join a band or choir

陕西省2020学年高一语文寒假作业3

高一假期作业 一、阅读下面的文字，完成1～3题。（每题3分，共9分） 中国诗歌自身的调节功能 中国诗歌之所以能历久而不衰，一个重要的原因是它本身有一种调节功能，其语言形式处在不断变化的过程之中。从四言到五言到七言，随着汉语的发展变化而不断形成新的节奏。二二节奏的四言诗是诗歌的早期形式，随着《诗经》时代的结束而趋于僵化。此后的四言诗，如曹操《短歌行》那样的佳作实在不多。中国诗歌主要的形式是二三节奏的五言和四三节奏的七言。四言诗一句分成均等的两半，节奏呆板。五七言前后相差一个音节，寓变化于整齐之中，节奏活泼。所以五七言取代了四言而成为中国诗歌的主要形式。为什么七言没有继续加长，发展为九言呢?我想这是因为一句诗七个音节已经达到读起来不至于呼吸急促的最大限度，加长到九言读起来呼吸急促。这样的诗行不容易建立起来。 在音节变化的同时，格律也在逐渐严密化。中国诗歌是从自由体（古诗）走向格律体（近体诗），但格律体确立之后自由体仍不衰退，而是和格律体并存着，各有其特长。就一个诗人来说固然有的擅长自由体，有的擅长格律体，但两方面的训练都是具备的。在自由体与格律体之间始终没有分成派别。它们互相补充又各擅其能，共同促使中国诗歌的繁荣发展。 从深层考察，诗歌的发展乃是性情与声色两种因素的交互作用。从重性情到重声色，是中国诗歌史的第一个转变，这个转变发生在晋宋之际，具体地说是在陶谢之间。这恰好也正是近体诗的各种技巧被自觉加以运用的时候。明代的陆时雍说：“诗至于宋，古之终而律之始也。体制一变，便觉声色俱开。谢灵运鬼斧默运，其梓庆之鑢乎？”具体地说，这个转变主要表现在两个方面，即从重写意转到重摹象，从启示性的语言转向写实性的语言。《文心雕龙·明诗篇》说：“俪采百字之偶，争价一句之奇；情必极貌以写物，辞必穷力而追新。”指出了转变后的状况。从陶到谢的转变，反映了两代诗风的嬗迭。正如沈德潜《说诗晬语》所说：“诗至于宋，性情渐隐，声色大开，诗运转关也。”重声色的阶段从南朝的宋延续到初唐，一方面丰富了表现技巧，另一方面也建立起严密的格律，到盛唐，性情与声色完美地统一起来，遂达到了诗歌的高潮。 但是性情与声色的统一毕竟不能维持多久。盛唐半个世纪一过，二者便又开始分离。重性情的，声色不足；求声色的，性情不完。此后二者统一的诗作虽然不少，但能以二者的统一维持一个时代的再也没有了。中国诗歌史总的看来是绚丽多彩的，但其最引人瞩目的顶峰也不过只有这么一个盛唐，半个世纪而已。 1．下列对中国诗歌自身“调节功能”的理解，不正确的一项是（） A．语言形式的调节功能还体现在格律的逐渐严密化：格律体取代了自由体。 B．其语言形式的调节功能体现在不断形成新的诗句节奏：五七言取代了四言成为主流。 C．“调节功能”是指历久不衰的中国诗歌在其发展过程中不断求变的一种特性。 D．调节功能还体现在性情与声色的交互作用，从而使中国诗歌呈现出不同的风貌。2．下列表述完全符合原文意思的一项是（） A．随着人们对《诗经》兴趣的降低，《诗经》的时代结束了，人们由此感觉到二二节奏的四言诗越来越僵化。 B．中国诗歌没有从五言七言发展成九言，是因为五言七言寓变化于整齐之中，节奏更为活泼的缘故。 C．明代的陆时雍和《文心雕龙·明诗篇》都指出了两代诗风的嬗迭发生在陶渊明和

My baggage, including my mobile phone, was blown away. ” Strangely Uncle asked, “The map?” I said, “The one you put in my sleeping bag.” Seeing the map, Uncle suddenly laughed again, “This is your 4-year-old cousin Linda’s painting of a Super Spider-Man.” I was surprised, “However, I really got this ‘map’ to find it down the road.” Uncle said, “You can come down the mountain successfully, not due to the map,

Fire!” What terrible words to hear when one wakes up in a strange house in the middle of the night! It was a large, old, wooden house and my room was on the top floor. I jumped out of bed, opened the door and stepped outside the house. There was full of thick smoke. I began to run, but as I was still only half-awake, instead of going towards the stairs I went in the opposite direction. The smoke grew thicker and I could see fire all around. The floor became hot under my bare（赤裸的）feet. I found an open door and ran into a room to get to the window. But before I could reach it, one of my feet caught in something soft and I fell down. The thing I had fallen over felt like a bundle（包袱）of clothes, and I picked it up to protect my face from the smoke and heat. Just then the floor gave way under me and I crashed to the floor below with pieces of burning wood all around me. I saw a doorway in fire, then I put the bundle over my face and ran. My feet burned me terrible, but I got through. As I reached the cold air outside, my bundle of clothes gave a thin cry, I nearly dropped it in my surprise. Then I was in a crowd gathered in the street. A woman in a night-d ress and a borrowed man’s coat screamed as she saw me and came running madly. She was the Mayor’s wife, and I had saved her baby. 1. When the fire arose in the middle of the night, the author was _______. A. at home B. sleeping C. sitting in bed D. playing games 2.The author saved the baby _____. A. because he was very brave. B. because he liked the baby very much. C. because he just happened to save it. D. because it was t he Mayor’s baby. 3. He ran in the wrong direction because he _______.
