    Take time off school, because your body will fight off the cold virus better if it is well rested. However, if you have to go, avoid close contact with your classmates.1. Meanwhile, wash your hands as frequently as possible. Nomsedating（非镇静的）allergy medicine, which you can buy from a chemist, can ease the problems of a runny nose and watery eyes.

As soon as you feel a cold coming on, drink plenty of liquid. Water or juice is ideal but hot herbal teas with lemon will help thin sticky substance and remove it from the body. A warm gargle with salt water will make your throat more comfortable by reducing the swelling. 2.

3. Breathing in steam over a bowl of hot water helps a lot, too. For a violent cough, the latest research suggests that honey, either straight from a jar or mixed with a hot drink, works as well if not better than costly sprays.

A good diet is also essential for a quick recovery, so start the day with a healthy breakfast including vitamin C in the form of fresh fruit. 4. For dinner, easily digested solid food is recommended, such as rice porridge made with vegetables or eggs.

5. It not only makes you physically stronger, but enhances your emotional well-being. Just remember not to attempt anything that requires a lot of effort or strength. Finally, to recharge your body and regain your strength, you need a full eight hours' sleep.

A.Besides, a little light exercise is beneficial as well.

B.As we know, the virus can be spread easily from one person to another.

C.The name “cold" came into use in the 16th century due to cold weather.

D.The warm air generated by a hot shower or bath will help clear blocked noses.

E.Signs and symptoms may appear less than two days after exposure to the virus.

F.For lunch, chicken noodle soup is good since it helps block cells that cause coughing.

G.It also washes out bacteria and viruses so it can be used as a preventive measure as well.

    Walls blanketed in moss(苔鲜)are popping up in major cities, along with promises that they can reduce air pollution—but can a few square metres of plant matter really deal with the smog?

A Berlin-based firm, Green City Solutions, believes so. Its moss walls, called the CityTree, are roughly 4 square metres in size. Armed with Wi-Fi sensors to monitor the health of moss, a City Tree functions autonomously and requires very little maintenance(维护). The wall collects rainwater, which is pumped through a built-in irrigation system to the plants, powered by solar energy. As a result, the firm says each CityTree is able to “eat” around 250 grams of particulate(颗粒) matter a day (nearly 90 kgs a year) and removes about 240 metric tons of CO2 annually. It also cools the surrounding air.

Aware that getting the surrounding air in contact with the moss wall is crucial for the CityTree to be effective, the inventors ensure that the location of each installation (安装) is chosen carefully. Spots where pollution is heavy due to traffic and where air flow is limited are picked. The importance of this step is explained by the fact that the waste gas from a car generally goes vertically a few kilometres into the air.

But this doesn’t mean moss walls will necessarily protect people from pollution. In the Netherlands, researchers found that eight walls installed in Amsterdam failed to reduce the concentration of particulate matter (PM) and nitrogen dioxide (N02). Their report concluded that even doubling the number of moss walls would do little to improve their effectiveness.

The CityTree is not meant for parks or to substitute for street trees, but to add greenery to concrete-heavy spaces where planting is not an option. It’s important to remember that street trees provide a whole host of other benefits, including shelter and habitat for urban wildlife, shade and cooling for people on the street, and reduction of urban heat islands.

C.How to operate CityTree.

D.Where to place CityTree.

3.Why is the example of Amsterdam mentioned in Paragraph 4?

A.To show that CityTree can’t always work well.

B.To prove that CityTree can reduce air pollutants.

C.To emphasize the necessity of building moss walls.

D.To analyze the reasons for the failure of the program.

4.What is the author’s attitude towards replacing street trees with moss walls?

A.Ambiguous. B.Disapproving.

C.Supportive. D.Cautious.

    From the cold Arctic to the African plains, every society seems to have some form of music as part of their culture. Music is so common and widespread that most people don’t even question it anymore. But until recently, there were researchers who doubted it: How could we know that music was really a part of all known societies?

Now, Harvard researchers, Samuer Mehr and Manvir Singh, have found further evidence to support the argument. They gathered music from different countries, media and time periods, and collected descriptions of many different pieces of music. Rather than focusing on music first and then looking at where it could be found, they started by studying a record of detailed descriptions of more than three hundred known global societies, and found that all of them have music as part of their culture.

To see if people could recognize the functions of songs from around the world, the researchers also created a listening experiment in which people tried to guess the behavioral context of a song. This went surprisingly well. Particularly music that was intended for dancing or to calm a baby were easy to recognize as either dance music or lullabies. Love songs were a bit more difficult to qualify, because they tend to be very diverse even within cultures.

This systematic study of connections sounds like the way that researchers in other fields would study biological patterns. “There’s a field known as cultural phylogenetics,” says Singh. Whereas biological characteristics are only received from parent to child, cultural characteristics (like music) are also shared between people of the same generation. That makes it much more difficult to figure out where the characteristic has come from.

“Finally,” Singh says, “We still don’t know why music developed gradually. Our study shows that humans everywhere share cognitive mechanisms (认知机制) that make certain sounds seem appropriate in particular contexts.”

A.To comfort a baby. B.To pick out love songs.

C.To create a context. D.To tell functions of songs.

4.What is the main idea of the text?

A.Music shapes societies in different cultures.

B.Global music shares common characteristics.

C.Musical systems display cultural differences.

D.Multi-culture is based on biological patterns.

Sharon Okpoe has lived her entire 17 years in Makoko, known as the world’s largest “floating slum (贫民窟)”, built on a lake in Lagos, Nigeria. Okpoe’s father is a fisherman, and her mother sells smoked fish.

As many as two-thirds of the city’s 21 million residents live in slums. “Most girls are trapped in a terrible cycle of poverty. Many of them are not thinking of education, a plan for the future,” Abisoye Ajayi-Akinfolarin, a computer programmer in Lagos, recalls. But several times a week, girls like Okpoe get a glimpse of another world when they attend GirlsCoding, a free program run by the Pearls Africa Foundation that seeks to educate and excite girls about computer programming. Since 2012, the group has helped more than 400 disadvantaged girls gain the technical skills and confidence they need to transform their lives.

It’s the vision of Ajayi-Akinfolarin, who left a successful career to devote herself to this work. She'd noticed how few women worked in this growing field-a 2013 government survey found that less than 8% of Nigerian women were employed in technology jobs. She wanted to fix the gender gap. “Technology is a space that’s dominated by men. Why should we leave that to guys?” she said. “I believe girls need opportunities.”

Now, dozens of girls aged 10 to 17 get trained in computer programming technology. “I believe you can still find diamonds in these places,” Ajayi-Akinfolarin said. “They need to be shown another life.” One way her program does this is by taking the students to visit tech companies — not only showing them what technology can do, but also helping them visualize themselves joining the industry.

Okpoe, for one, has taken this to heart. She helped create an app called Makoko Fresh that went live this summer, enabling fishermen like her father to sell seafood directly to customers. She even wants to become a software engineer and hopes to study computer science at Harvard. “One thing I want my girls to hold onto is, regardless of where they are coming from, that they can make it,” Ajayi said. “They are coders. They are thinkers. Their future is bright.”

A.It encourages girls to land a job in education.

B.It offers Nigerian girls in need part-time jobs.

C.It helps girls working in Lagos to fight poverty.
