In cold winter days, as you have probably noticed , germs（细菌）are everywhere―runny noses, sore throats, nothing quite like the common cold to make you feel miserable and terrible.
But some experts believe that there is no relation between cold weather and catching colds. So why are we particularly weak and easy to catch a cold during this season?
Internal Medicine expert, Dr Meenakshi says, “One reason could be the truth that people are likely to stay indoors, so the virus can spread easily among people. Also the virus grows better in wetness.”
The common cold is a viral infection that can be caused by any of up to 250 kinds of virus ,the most common group of which are the viruses that hit the nose. They are responsible for anywhere between one third and half of all common colds. Dr Jain says, “ these viruses are transmitted through the nose and respiratory passages（呼吸道）, by touch, and by contact with airborne particles （空气微粒）that are created by sneezing or coughing.”
Medical experts also say that there is no cure for the common cold and even antibiotics （抗生素）are of no help . However , there are some prevention measures which can be of some help.
S Wash your hands regularly, so that germs get killed.
S Don’t touch your eyes, nose and mouth, which can limit your chances of infection
S Don’t share drinking glasses with anyone else, as this will prevent the spread of the virus.
S Drink lots of fluids, especially hot water, to avoid dryness.
S Make sure to eat enough fruits to increase your immune system .
S Get enough sleep and you’ll certainly become stronger to fight against the virus.

A new study by Penn State College of Medicine research team found that honey is a better and safer treatment for children than cough medicines.
Ian Paul, the study’s lead researcher, was motivated to test honey because treating coughs in children has recently become a sticky subject. Coughing is the body’s way of cleaning irritated (受刺激的) airways to help you breathe. But too much coughing can irritate your lungs and throat even more. It can also make it tough to get the sleep your body needs to heal. Hoping to ease the suffering of their children, parents often give them cough medicines.
But there have never been any good studies showing that they work. Cough and cold medicines may also cause serious side effects. Hundreds of kids die in the hospital each year after receiving too much cough medicine by mistake. Last October, the US Food and Drug Administration suggested that parents should not give cough medicines to children under 6.
In order to search for a different solution, Paul designed a study that involved 105 kids who were sick with coughs and other cold conditions. At bedtime, the kids took buckwheat(荞麦) honey, honey-flavored (蜜蜂味的) DM (one of the most common ingredients成分in cough medicine), or no treatment. Parents and kids in the no-treatment group knew they weren’t getting anything, but the other two groups weren’t told which treatment they were getting.
The surveys showed that kids who swallowed about 2 teaspoons of buckwheat
honey before bedtime coughed less and slept better than kids in other groups.
“When parents want something for their kids to take,” Paul says, “honey seems
like the best option.”
But what gives honey its healing power? Substances called antioxidants(抗氧化剂) may be part of the answer. All honey contains antioxidants that protect our cells from damage. Studies show that antioxidant levels in the body rise after someone swallows honey.
Which of the following can be the best title for this passage?
A. Sweet solution to kids’ coughing
B. No cough medicines to children
C. Best treatment for your cold
D. Cough medicines don’t work
We can learn from Paragraph 2 that coughing ______.
A. can cure lung and throat diseases
B. is more harmful to children
C. sometimes does good to people
D. helps improve children’s die
During Paul’s experiment, the kids who received treatment __________.
A. seemed much worse than before
B. had no idea what they swallowed
C. knew they weren’t getting anything
D. coughed less and slept better
According to the passage, Paul’s experiment proved that ____.
A. honey may have real healing power
B. cough medicines may cause side effect
C. cough medicines don’t really work
D. buckwheat honey contain more antioxidants
