Anger and other strong emotions (情感) can probably cause deadly heart beats in certain weak people，the US researchers said on Monday.
Earlier studies have shown that earthquake，war or even the loss of a World Cup Soccer game can increase chances of death from sudden cardiac arrest，in which the heart stops passing blood.
“It’s certainly been shown in all different ways that when you put people under pressure，sudden death will increase，” said Dr.Rachel Lampert of Yale University in New Haven，Connecticut.
“Our study starts to look at how this really has an effect on the electrical system of the heart，” Lampert said.
She and her assistants studied 62 patients with heart disease and ICDs that can discover dangerous heart beats and send an electrical shock to bring a normal heart beat back.
Patients in the study took part in an exercise in which they told a recent angry period while Lampert’s team did a test called TWave Alternant that measures electrical instability(不稳定性) in the heart.
Lampert said the team on purpose asked questions to get people to experience the angry period again.“We found in the lab that yes，anger did increase this electrical instability in these patients，” she said.
Next，they followed patients for three years to see which patients later had a cardiac arrest and needed a shock from their ICDs.“The people who had the highest anger were 10 times more likely than everyone else to have cardiac arrest，” she said.
Lampert said the study suggests that anger can be deadly，at least for people who are already weak to this type of electrical disorder in the heart.From the passage we know cardiac arrest refers to ________.
| A．someone who will be caught if he does something wrong |
| B．some place where you can show all your feelings |
| C．some disease that can kill people instantly |
| D．something used by patients in hospital |
The underlined word “this” in Paragraph 4 refers to “________”．
| A．feelings of anger and pressure |
| B．games |
| C．feelings of happiness |
| D．hunger |
What did Lampert use to measure electrical instability of patients’ heart?
| A．ICD and TWave Alternant test. |
| B．ICD and Cardic arrest. |
| C．Cardiac arrest. |
| D．The passage doesn’t tell us. |
The passage is mainly about ________.
| A．new findings for heart disease |
| B．that anger really can kill a person |
| C．a new test of measuring heart blood |
| D．a study showing danger of heart beats |
Recently a man came to me，because he was told that there was fluid around his heart. After trying many drugs which were of no use to reduce the fluid，he was told the only other choice was to have an operation. He refused because he knew that every illness has a mental cause and that if he had the operation but did not clear the mental cause，the fluid would return. At last，he searched the Internet to find a metaphysical healer (自然力治疗师)，and he found me.
The mental cause of his disease was an experience of breaking up five years ago with several friends，whom he had known for over twenty years. This experience broke his heart. Not knowing how to “mend” his broken heart，his body created a “repair” by surrounding his heart with fluid to protect it from the sad feelings.
Our work focused on reminding him of the feelings of being loved and forgiving his friends. Months later，his heart was mended and the fluid disappeared. He left my office after the final session with a smile on his face and a spring in his steps.
The key is: to create a healthy body，you must be healthy not only in body，but also in mind.
To be mentally healthy，you need to build up strong relationships. Creating strong relationships will insure that you are accompanied by a network of loving persons. It is important for building a support system that boosts your spirits. Even when you are alone，you will not feel lonely or upset. Strong relationships are not spaceships－they are not hard to build.The underlined word “boosts” in Paragraph 5 is closest in meaning to ________.

When my mom and dad said that we could adopt a couple of cats，I jumped at the chance to have some lovely animals around the house. So we went to the Humane Society where there were a lot of animals up for adoption. The first thing I noticed was that there was not a lot of room for the animals and not a lot of supplies to care for them. Even though they didn’t have much，the people who worked there tried to care about the animals. Still，it seemed they had no enough food and medicine to keep the animals healthy.
My family and I finally decided to adopt two cats we named Sox and Sierra. We went up to the front desk to sign the papers for them，and that’s when I noticed a box on the counter. The Humane Society was hoping to get enough donations to buy more supplies for the animals and also build a new building to help more animals.
Later that day my mom and I went shopping，and as we were walking through the parking lot at the store，I noticed a green piece of paper not far from our car. It was kind of wet，but it looked like it could be a dollar bill，so I walked over and picked it up. It wasn’t a dollar bill－it was a twenty-dollar bill!
When I got home，I dried it off and thought about what to do with it. I considered spending it on a toy and a lot of other things. Right then，Sox climbed up onto my lap，and I knew what I was going to do with the money.

My 17yearold daughter went off to college and having her away from home brought back memories of watching Peter Pan when she was little. In the classic TV production，one scene in particular impressed me: when Mrs. Darling puts her children into bed. As she turns off the last of the night lights，she takes one last look at the bedroom and says，“Dear night lights，protect my sleeping children.” As a mother，I know how much she loves her children.
It has been several weeks since we took our daughter to college and she seems to be adjusting (适应) well after a short period of homesickness. For us，though，it’s another story. Like most parents，I love checking in on my children at night. But now she’s gone，and I find nighttimes the hardest. I miss her most at night.
In my neighborhood，most of the parents whose kids are off to college are dealing with similar melancholy. My husband is filled with anxiety. One friend talked about getting this sick feeling in her stomach as she prepared for the college drop-off We complained that many of us were too busy to truly enjoy being with our children while we had them.
For us moms，seeing Toy Story 3 only made the sadness worse as we watched the character Andy，who is the same age as our kids，say goodbye to his childhood as he prepares to leave for college. And it’s not just “first-time” parents like me. Two moms who have kids already well into college said the separation didn’t get any easier.“You feel like something has been taken away from inside you，” said one of them.
I imagine things will get easier with time，especially as I see my daughter adjust to college life. Meanwhile，as I keep my cellphone close to me in bed and text my daughter goodnight and sweet dreams every night，I like to think at messages serve as a night light that keeps her safe.The writer was deeply impressed by the scene in Peter Pan because ________.

Almost everyone feels sleepy sometimes during the daytime. Being sleepy may get in the way of your daily work，childcare，and even activities for fun. Here are some ways to improve nighttime sleep and avoid daytime sleepiness.
1．Get adequate nighttime sleep.
That may sound obvious，but many of us cut down an hour or two off our sleep time in the morning or at night to do other things. Most adults need seven to nine hours a night，and teenagers usually need a full nine hours. Block out eight or nine hours for sleep every night.
2．Keep distractions out of bed.
“Remember your bed is only for sleep，” says the scientist.“You shouldn’t read，watch TV，play video games，or use laptop computers in bed.” Don’t do your bills or have heated discussions in bed，either. They may leave you sleepless.
3．Form a good habit.
You should form a good habit of going to bed and getting up at the same time at night and in the morning，including on weekends.
4．Gradually move to an earlier bedtime.
Another way of getting into a consistent (始终如一的) schedule is to try going to bed 15 minutes earlier each night for four nights. Then stick with the last bedtime. Slowly getting used to your schedule like this usually works better than suddenly trying to go to sleep an hour earlier.
5．Set consistent，healthy mealtimes.
Regular mealtimes，not just regular sleep times，help regulate our circadian rhythms (生理节奏)．Eat a healthy breakfast and lunch on time instead of grabbing a piece of cake and coffee in the morning or a late sandwich on the run. Try to finish eating meals two or three hours before bedtime.
6．Exercise.
Regular exercise offers many benefits for sleep. Exercise generally makes it easier to fall asleep and sleep more soundly.The writer wrote this passage to ________.
