Experts note that an unhealthy lifestyle can put you at great risk of heart disease and stroke. So doctors urge us to eat healthy foods, get exercise, stop smoking and limit our alcohol intake. But there is something else you can do. And it is free and easy. Smile!
Dr. Chockalingam, a heart disease specialist in Columbia, advises his patients to smile. He says a smile may be one way to help your heart. “When we smile, the brain wiring changes. The chemicals that are released are more positive.” He says smiling is the first step in fighting physical and emotional stress and its sometimes harmful effects on human health. This is not just New Age advice. Several studies support his opinion.
When you feel stressed or under pressure, your body releases many natural hormones (荷尔蒙) including adrenaline and cortisol. Adrenaline increases your heart rate and blood pressure. Cortisol is the body’s main stress hormone. It increases sugar in the bloodstream. If you are truly in danger, these hormones can help you. They are part of what we call our fight-or-flight response.
However, when we are stressed for a long period, these stress hormones are ever-present in our bodies. And that, medical researchers warn, may lead to health problems.
Researchers say the connection between stress and heart disease is still unclear. However, they claim that when people are stressed for long periods of time, they may have an unhealthy lifestyle, which can lead to health problems.
Dr. Chockalingam says a smile may be one way to help. He tells his patients to smile 20 times an hour. To some, that might seem like a lot of smiling. Or some might even feel foolish ... smiling for seemingly no reason. But a smile does not involve drugs. It is not invasive like a surgical operation. It is free and it has no bad side effects.
“Once people smile, they are relaxing. This relaxation directly lowers blood pressure, improves sugar levels in the blood. If we are smiling, we are breaking that link between stress and health.” And it just may provide a little extra protection to everyone’s heart health.

Have you ever heard a rumor spread around by students at your school? Rumors, like fake news, can often misinform individuals and lead them to believe false information.
In an attempt to settle this problem, the country of Singapore has passed a bill that bans companies and individuals from publishing false information online.
This law, known as The Protection From Online Falsehoods and Manipulation Bill, has caused a public outcry (强烈的抗议), as the government has been given the power to remove content that it considers inaccurate or against the public’s interest.
Since Singapore’s citizens are part of different racial and religious groups, the government fears that rumors or fake news can increase tensions within an already small country.
With the new law coming into effect, Singapore’s government now has the authority to monitor news sites, social media platforms, and other databases of information to determine whether the content is falsified. The government can order for the removal of fake news, and publishers of this information can receive prison time and fines up to one million Singapore dollars!
Critics fear that the bill threatens their freedom of speech and freedom of expression. Since national issues and world news are generally discussed on online platforms, many are concerned that this new bill will prevent individuals from talking freely and having healthy conversations.
Several companies, including Google, Facebook, and Twitter, have offices situated in Singapore, meaning that the new law will affect their company operations. Social media companies in Singapore could face a decline in activity, as users may fear posting their opinions and being punished by the government.
Others are concerned that the law does not clearly state what a “false statement” is. Such an ambiguity might allow the government to misuse their power, even though the intention is to curtail the mow of false information and rumors throughout Singapore.
This law does give rise to several concerns related to freedom and privacy and it will be interesting to see what Singapore’s government will do to deal with this problem.
1.Why are some people against the bill?
A.They think the bill can’t get rid of fake news.
B.They belong to different racial and religious groups.
C.They think their freedom of speech may be harmed.
D.They don’t want to increase tensions in their country.
2.What does the government have the right to do under the new law?
A.Punish publishers of fake news.
B.Monitor telephone conversations.
C.Prohibit certain people from going online.
D.Fine fake-news makers any amount of money.
3.How will the new law affect social media companies in Singapore?
A.Their users’ privacy may be disturbed.
B.Their income will increase very slowly.
C.Their illegal activities will come to light.
D.Their social media may become less active.
4.What does the underlined word in paragraph 8 probably mean?
A.prove B.accelerate
C.promote D.decrease
A few years ago, my husband Charlie and I had marital problems. Growing family responsibilities and financial worries took a toll on us and we began arguing frequently, often late into the night.
However, neither of us could take the step that would end our eleven-year marriage and bring heartbreak to our three young children. Deep down we knew we still loved each other, so we determined to work it out. Through countless discussions, we began to close the gulf. The more honest we were, the closer we became.
When I felt we were reaching solid ground, I asked my husband to give me an “eternity (永恒) ring”. It was not so much the ring I wanted; it was the reassurance (保证) I thought it would bring.
We went shopping on a beautiful summer day. We walked hand in hand along a row of jeweler’s shops. Finally I found a ring I liked. While waiting for it to be adjusted, the jeweler took my left hand and glanced at my engagement ring. “May I clean it for you?” he asked. “It really doesn’t sparkle like it used to.” Charlie said as I slipped the ring off my finger. A few minutes later the jeweler was back. The ring shone like new!
On the drive home, I didn’t take my eyes off it. I forgot all about the eternity ring. I just couldn’t believe how this old ring suddenly sparkled the way it had the day Charlie gave it to me. I had taken it for granted these past years, but with a little polish it could still make my heart beat fast.
And that’s the way it is with a marriage. You have to work at keeping it polished and new, or else the grime (污垢) of the passing years will hide the joy. I put my hand on the seat between us and spread my fingers. Charlie covered my hand with his. I felt I was lucky to be able to see the sparkle in something gold when I thought I needed something new.

Hope everything goes well with you. In terms of your unhealth lifestyle, I'm writing to give you some suggestion.
First of all, green and nutritious foods are necessary to our daily life, without that we can't build a healthy body. However, it's time that you can eat more fruits and vegetables rather than fast food. Drinking water instead of coke cola is wise choice. Second, you're supposed to cut down the time spending on the electronic products, which it is beneficial to your eyes and brain.
The last point to bear in mind is that early to bed or early to rise will make a man healthy, wealthy and wisely. Hope my advice can benefit you.
