Effective Ways to Deal with Joint(关节)Discomfort

Joint discomfort is a common problem, but most people who suffer from it don’t know the proven ways that you can find relief. There are several ways for helping your joints.1.

Drop the extra pounds. We all know that losing weight improves health in many ways, so it shouldn’t come as a surprise that it does the same for joint health. 2.Less pressure on your knees will help prevent joint damage from happening. When it comes to losing weight while you have joint discomfort, low impact exercise is the best. Strength training, stretching, and yoga for those hoping to strengthen and support their joints are recommended. Aerobic(有氧的)exercises also help decrease sensitivity to pain through exercise.

3.Having a balanced diet combined with keeping a healthy weight seems to have the best long-term result for preventing joint damage. Another way is to stop eating foods that can cause inflammation(炎症).

Use thermal therapy and cold compresses. 4.If you experience a lot of stiffness(僵硬)in the mornings, a warm shower or heat pack will help loosen up the tissues and joints and provide relief. 5.Apply the ice or cold pack by wrapping it in a thin towel and applying it over the area for 10 minutes. This helps cool down the area, reduce the inflammation, and relieve pain.

Although there’s no perfect solution to make joint discomfort disappear, adding these lifestyle changes into your daily schedule can be really good for your joints.

A.Change eating habits.

B.What you eat doesn't make a difference.

C.It's better not to move when you're having joint discomfort.

D.However,if you're feeling joint pain ( not just stiffness)，icing is the best way.

E.For every one pound you lose, that’s four pounds of pressure off of your knees.

F.And more than likely, there's one that you don't yet know about that can help you.

G.Using heat and ice to treat joint discomfort is a time- tested and good choice for many.

    We know that reading is good for children. Now, a new study suggests that just being around books has its benefits. A team of researchers in Australia finds that growing up with a large library at home improves literacy( 读写能力) ,number-sense , and even technological skills in later life. It appeared in the journal Social Science Research.

The researchers were exploring the advantages of scholarly culture. They were interested in a curious observation that some call the “radiation effect".“Radiation effect is a situation where children grow up around books , but they don't read books. But somehow books benefit them, even though they don't read them as much as their parents wish them to,” said Joanna Sikora , a sociologist in Australia. Joanna and her colleagues analyzed data collected between 2011 and 2015 by the Organization for Economic Development. The survey assessed the literacy，numeracy(计算能力) , and technological competency of more than 160 , 000 adults from 31 countries. And it included a question about how many books participants had in their homes during adolescence.“What we were able to make clear was that people growing up around books had better literacy , numeracy and digital problem-solving skills than people who had fewer books growing up but had similar education levels , similar jobs ，and even similar adult habits in terms of reading or working at various numeracy-improving activities," she said.

In fact , teens who only made it through high school but were raised in a bookish environment did as well in adulthood as college graduates who grew up in a house without books. Now , how might mere exposure lead to intellectual improvement?“If we grow up in a house , in a home where parents enjoy books , where books are given as birthday presents and valued , this is something that becomes a part of our identity and gives us this lifelong urge to always come close to books and read more than we would.”

So keep shelves piled with books. Your kids will not only be grateful, they'll be more likely to be able to spell “grateful" correctly as well.

    Self-driving cars have been backed by the hope that they will save lives by getting involved in fewer crashes with fewer injuries and deaths than human-driven cars. But so far, most comparisons between human drivers and automated vehicles have been unfair.

Crash statistics for human-driven cars are gathered from all sorts of driving situations, and on all types of roads. However, most of the data on self-driving cars' safety have been recorded often in good weather and on highways, where the most important tasks are staying in the car's own lane and not getting too close to the vehicle-ahead. Automated cars are good at those tasks, but so are humans.

It is true that self-driving cars don't get tired, angry, frustrated or drunk .But neither can they yet react to uncertain situations with the same skill or anticipation of an attentive human driver, nor do they possess the foresight to avoid potential perils. They largely drive from moment to moment, rather than think ahead to possible events literally down the road.

To a self-driving car, a bus full of people might appear quite similar to an uninhabited corn field. Indeed, deciding what action to take in an emergency is difficult for humans, but drivers have sacrificed themselves for the greater good of others. An automated system's limited understanding of the world means it will almost never evaluate ( 评估) a situation the same way a human would. And machines can't be programmed in advance to handle every imaginable set of events.

Some people may argue that the promise of simply reducing the number of injuries and deaths is enough to support driverless cars. But experience from aviation (航空) shows that as new automated systems are introduced, there is often an increase in the rate of disasters.

Therefore, comparisons between humans and automated vehicles have to be performed carefully. To fairly evaluate driverless cars on how well they fulfill their promise of improved safety, it's important to ensure the data being presented actually provide a true comparison. After all, choosing to replace humans with automation has more effects than simply a one-for-one exchange.

1.What makes the comparison between self-driving cars and human-driven cars unfair?

A.Self-driving cars never get tired. B.Statistics are collected differently.

C.Machines can make decisions faster. D.Self-driving cars know the world better.

2.What does the underlined word”perils” in Paragraph 3 most probably mean?

A.Dangers. B.Self-driving cars. C.Pedestrians. D.Human-driven cars.

3.In which aspect can self- driving cars beat human-driven cars?

A.Driving steadily. B.Climbing steep slopes.

C.Evaluating the cost of loss. D.Making complex decisions.

4.Where is the text most likely from?

A.A poster. B.A novel. C.A brochure. D.A magazine.

    My name is Matthew. I'm not someone who has many secrets，because I'm a terrible liar. But there is one huge secret that I kept for years- -I failed my driving test. I had never failed a test before, and had never even come close. Driving made me anxious , but my parents told me I had to. They signed me up for driving lessons. I had gotten a perfect score for my written permit exam , but getting behind the wheel was a different story.

But when October 30th rolled around ,my pride set in. I wanted to be like everyone else at my school , showing off the brand new license they'd gotten. Looking back on that special day,I can't remember if I was nervous. What I do remember is starting the test , pausing at a stop sign after a few seconds , and being asked by the instructor to pull over. I had received an auto-fail since my pause was indeed a pause and not a real stop. I wasn't upset that I was leaving without a license, but I was scared everyone would know that I had failed. So when I got to class, I told everyone I didn't want to take the test on my birthday.

One Friday a month later, I went to the test spot again and passed. Later that night I drove for the first time by myself, which brought to me an amazing feeling I've never experienced——but sill, I couldn't imagine ever telling anyone the truth. So I didn't. It wasn't until midway through college that I came clean. It turned out plenty of my college friends had failed too! And I gathered enough courage to speak the fact out. Yes ,I had also failed.

Now I realize failure and imperfection are two things everyone has to experience , without which one couldn't make a true man.

4.W hat did Matthew learn from his own experience?

A.Honesty is the best policy. B.Failure is a way to grow up.

C.Truth stands the test of time. D.Imperfection is another form of perfection.

Great Activities for Nature Lovers

Hiking

One of the easiest and most accessible ways to get close to nature is by setting out on a good old fashioned hike. Hiking generally doesn't require any fancy equipment or special skills, just a piece of map and a thirst for adventure. This activity can be as relaxing as you make it.

Backcountry Camping

Why limit yourself to just a day hike when you can have a full weekend for a longer adventure? Backcountry camping involves packing your tent，sleeping gear ,food, and water on your back to set up camp in a remote location. I you’re an experienced hiker and camper ,this is an excellent way to test your survival skills and explore the wilderness.

Mountain and Road Biking

Unlike long hikes through the woods , biking allows you to cover more ground and travel farther in nature. Mountain biking typically involves riding up and down steep slopes , between trees , and over rocks. If this sounds too intense or your tires aren't suited for rugged terrain( 地形) , consider taking a road bike on paved trails through forest preserves or along country roads.

Gardening

Contrary to popular belief, you don't have to travel beyond your own backyard to experience the beauty of nature every day. If your personality is less adventurous or your mobility restricted, consider planting a garden to grow your own vegetables , fruit , herbs，or flowers. There's something truly satisfying about mixing up a salad with fresh ingredients you grow yourself. One of the best parts about spending time in gardening is that it doesn't have to break your budget and anyone can do it.
