Then after compressions 7.(complete), check the air way 8. (see)whether the person is breathing. If not, perform mouth-to-mouth rescue breathing, 9.helps to move the oxygen down into the victim’s lung. And chest compression should start again right after the two breaths are given.
Learn CPR, for you never know when you might need 10.. And it feels good to know that you could help in case of emergency.

There are great health benefits from walking: slimmer waistline, better emotions, more focus, a stronger immune system and balanced blood levels.1.But walking with good habits will strengthen those benefits as well as avoid any injuries. Here are the ways on how to walk properly.
2.
Although everyone has their own way of walking, certain common behaviors can improve almost everyone’s walking experience. Chief among these is your posture(姿势).As you walk, keep your head upright, your back straight, and your chin up. Otherwise, bad posture can lead to back pain, an inflexible neck, and even more serious diseases.
Add warming up
Before your workout, make sure you stretch (伸展) muscles to avoid injury.3.Not only may you get injured, but it will also get you tired even quicker. Start with a walk at a normal pace and then slowly increase the pace.
Swing your arms
Don’t hold your arms tight by your side. If so, it looks awkward and also limits walking pace. Your walking pace will become faster as long as you swing your arms. If weather permits, try to keep your hands out of your pockets. 4.
Time your walks
When walking, the time you do so matters. Make sure you walk a few minutes after you eat, not immediately. That way, your body can still digest what you just ate before a workout.5.May it be 15-30 minutes every day, find time to walk and exercise, keeping your body active.
A. Relax before walking.
B. Stand straight while walking.
C. Don’t go walking at a high speed immediately!
D. It’s best to create a schedule suitable for your lifestyle.
E. In other words, walking can make you happier and healthier.
F. Doing so allows you to walk faster and farther than you would otherwise.
G. Having your shoulders pulled back makes you more confident and greater!
A genetic variant(基因变体) that allows people to feel fully rested with fewer than six hours sleep a night has been found. It is the second such finding in recent months.
Ying-Hui Fu at the University of California, San Francisco, and her colleagues have been seeking out genetic variants responsible for short sleep and genetically engineering these variants into mice to confirm their effect. In August. the team found a variant in a gene called ADRB1, which allows 12 members of a family to sleep 4.5 hours per night without feeling tired.
Now the team has found a variant in a gene called NPSR1 in another family, in which one sleeps averaged 5.5 hours a night and the other just 4.3 hours, feeling fully rested. Another variant in NPSR1 has previously been linked to people requiring 20 minutes less sleep than average, based on studies of tens of thousands of people.
Generally, long-term lack of sleep can contribute to many disorders, including obesity, heart disease, high blood pressure and depression. As far as Fu’s team has been able to tell, however, people who sleep less with one of these gene variants are healthy and don’t appear to suffer any ill effects. However, to be absolutely sure would require long-term studies involving large numbers of people, which is not feasible(可行的).
It might be possible to develop drugs that mimic the effects of these variants. However, as NPSR1 is also involved in processes such as stress, anxiety and fear, there is a risk of serious side effects.
1.What did Fu’s team do to confirm the variants effect?
A.Observed blood pressure change.
B.Tested genetic variants on mice.
C.Sorted the effects of different genes.
D.Studied those sleeping less than average.
2.What can we learn about Fu’s team?
A.They are researching variants controlling sleep.
B.They study NPRS1 in a family of 12 members.
C.They have developed drugs to test normal people.
D.They will discover more variants in a week.
3.What does the word “mimic”in the last paragraph mean?
A.Reproduce. B.Compare. C.Avoid. D.Reduce.
4.Where does the text probably come from?
A.A news report. B.A health magazine.
C.A research paper. D.A biology textbook.
A months-long drought affecting most of southern Africa has led to serious food shortage for millions of people.
The United Nations estimates(估计 )that more than 11 million people are facing extreme lack of food. The World Food Program says southern Africa has received normal rainfall in just one of the past five growing seasons.
Among the hardest hit areas is South Africa’s Northern Cape province. There, many farmers are struggling to keep their families and animals alive as they lose money and debt grows. Sheep farmer Louis told the AP he had lost more than 400 sheep over the past two years. He said this drought was the worst during his 45 years of farming. He got emotional while explaining that he now accepted donations of animal feed so he could keep the rest of his animals alive.
It’s estimated that this area will need at least $28 million over the next three months to assist 15, 500 affected farms. So far, South Africa’s government has promised $2 million.
Gertruida from Vosburg told the AP things had gotten so bad that she shared her family’s food with their animals. Small children were hungry, too. At Vosburg’s only school, Delta Primary School, large groups of children lined up for what became both breakfast and lunch. The meal usually included corn meal, vegetables and soup. “It’s very hard for the parents to actually feed their children at home, “one teacher said.
In Kimberley, the capital of Northern Cape, government officials give out money from the $2 million disaster aid program. The job can be difficult because some farmers live in places that are not easy to get to.
1.Which of the following is TRUE about the drought?
A.It has lasted a whole month.
B.It is the worst in Africa’ s history.
C.It has killed 400 sheep altogether.
D.It affects Northern Cape worst.
2.Why were Louis’ feelings out of control?
A.Because his debts grew.
B.Because he got donations.
C.Because he lost more sheep.
D.Because his children went hungry.
3.What’s the text mainly about?
A.Government takes measures to fight the rare drought.
B.People carry out self-rescue after the severe drought.
C.Farmers suffer a loss of animals because of the drought.
D.Deadly drought in Southern Africa leaves millions hungry.
