As we know, it is common for people to catch a cold in winter and most people believe they know the reason for colds. However, scientists say people have some wrong beliefs about the cause of colds.
Many people think that once you get infected by colds, you will not be easy to be attacked by colds for the rest of your life. That’s not the case. There are about 200 different viruses that cause the common cold. You catch a cold because of one kind of them this time, but you might catch a cold next time because of another.
Others believe that people get sick just because of the cold weather in winter. That is also wrong.
It’s because people tend to stay closer in winter and the cold virus is transmitted from one person to another through handshakes, sneezing, or coughing.
While there is no actual cure for the common cold, scientists say there are still a few things you can do to help you. Some experts say honey and chicken soup are effective against colds. Especially honey. There is increasing evidence that it helps shorten the duration of the common cold sometimes even by two to three days particularly in children. Chicken soup also helps reduce the duration of the cold.
In addition, if you do have a cold and you don’t feel like eating anything, it’s not going to hurt you but you have to drink a lot and you can drink water or tea because doctors say the water cycle in your bodies helps to cure colds. That’s very important. Though there is more than one way to deal with colds, doctors say the best advice is to continue using whatever works best for you.
【小题1】We know from the second paragraph that ______.

From the outer of New York to the heart of Singapore, nature is everywhere you're not looking in some of Earth's most crowded big cities. Outdoor adventure is often just a few stops on the train - or a short drive- away from the annoying crowds.  Here are a few favorites to get you going:

Mount Hollywood Trail, Los Angeles

It's not a skyscraper or a Ferris wheel, and there's no expensive restaurant up top. But if you want an absolutely unforgettable, no-admission-charged, 360-degree view of the entire Los Angeles region , it's yours. All you have to do is walk a little. One of the preferred exercise routes, the Mount Hollywood Trail, is easily accessed from the parking lot of the famous Griffith Observatory; you see what you get at the end of this steep 1.5-mile trail, which winds its way through the Griffith Park wilds up to the mountain's 1,640-foot peak.

Bronx River, New York

It may not be on your Top 10 list of things to do when you finally get to the Big Apple, but exploring the almost-secret river that flows through one of New York's most mysterious boroughs (自治市) is an unforgettable experience. The Bronx River Alliance, a non-profit group that has worked tirelessly to bring the much-abused river back to life , operates cycling and canoeing trips along the river, from the rugged Hunts Point section down near the harbor on up through the borough.

Southern Islands, Singapore

Believe it or not, tightly packed Singapore does have plenty of open space left . There are actual trails right in the middle of everything, if you know where to look . But to really get away from it all, the Southern Islands, a small group of little green dots just off the city-state's southern shoreline, are just the thing.

Lee Valley, London

This East London river valley changed last summer, when anyone near a television got an eyeful of Olympic Park, built directly in the middle of the valley. Inside the park, beautifully landscaped sections quickly became a favorite relaxation spot for games goers. At present, you'll find miles of walking paths worth exploring. Start at the Waltham Cross train and follow the signposted walking route southbound, guiding you past important historic industrial areas, through interesting city neighborhoods, past the western side of Olympic Park and on to the Thames.

Humankind has tried to improve its standard of living since the very beginning of civilization. Back then, as well as today, providing food and security was the basic task for a person. However, nowadays the range of required goods has expanded significantly. People feel the need for not only some primary things, such as a piece of bread and a roof over their heads, but also for various facilities and luxuries. Providing humanity with these things is connected to the use of natural resources, which requires energy. In turn, the common sources of energy we use today cause pollution, so economic growth is almost unavoidably associated with environmental damage.

Economic growth is the increase in numbers of goods and services produced over time by an economy, and it is calculated in terms of real Gross Domestic Product (GDP). Before growth is calculated, inflation (通货膨胀)is adjusted in order to take into account its mis­leading effect on the price of goods and services. Economic growth can also be explained as the increase in expected output, which results from an increase in actual output, or total de­mand.

There are certain aspects of economic growth which affect the environment. The first of these is the fact that in order to produce more goods and products, at a faster rate, the construction of large industrial plants is required. These plants produce a lot of waste, leading to the pollution of water and the atmosphere, which may cause negative long term health effects to nearby populations of animals, or people. They also lead to global warming.

Industrial manufacturing leads to the constantly increasing energy consumption. The traditional energy sources, which are commonly used nowadays, are considered to be the greatest polluters to the environment. There also exist so-called eco-friendly sources of energy. They are sometimes preferred but replacing the traditional sources with them also requires time, during which people have to make some sacrifices to support these undertakings.

In order to produce economically practical energy, a sometimes significant transformation of the natural site is often inevitable. This is expensive and, has harmful effects on the environment. Application of wind energy would block airflows’ natural speed which is the reason for their decrease in strength, after crossing the windmill. Consequently, the pres­sure balance that is brought about by this current will be affected, and it is important to re­member that the environment and weather conditions are directly affected by atmospheric pressure.

For these reasons, bringing about economic growth without any resulting environmental damage, whatsoever, is impossible.

1.What does the passage mainly talk about?

A． Pollution caused by plant construction.

B． Effects of windmills on the environment.

C． Economic growth and human civilization.

D． Economic growth and environmental damage.

2.What does the underlined word “They” in the third paragraph refer to?

A．Goods and products                     B．The industrial plants

C．Water and atmosphere                   D．Negative health effects

3.According to the passage, the author holds the opinion that ______.

A． economic growth should be calculated in terms of GDP

B． use of natural resources causes no damage to the environment

C． industrial manufacturing may cause damage to the environment

D． a windmill is a perfect way to produce economically practical energy

For years, researchers have looked into a possible relationship between heat and violence. There are conflicting results over whether there is an actual connection between rising anger and rising temperature, but the murder rate constantly increases during the months of July and August, according to the FBI’s annual crime report.

Many police chiefs say they put more policemen on the streets when the heat rises. “Calls for service always increase from May, June, July and August,” said New Bedford’s Captain Richard Spiriet. “The longer period of time you have the heat, the worse it is. It’s just the opposite in the winter time.”

Craig Anderson, a professor and specialist in social psychology at Lowa State University, argues the evidence is clear. “As the temperature goes up, people become more uncomfortable. They become easier to get angry,” he said. “That increases the possibility that a small conflict will be interpreted as more major.” Anderson conducted a couple of studies looking at crime rates over the course of several years within the same area to see when most violent crimes occurred. He found that violent crimes were more likely to occur on hot days and hot months － even hot years had higher violent rates than cold years, according to his research.

Other research shows it is not so much the physical climate, but rather the social climate, that causes increased violence. “During the summer months, people stay up later. They talk with their neighbors. They party with their friends,” said Jack Levin, director of the Brudnick Centre on Violence at Northeastern University. “There are more likely to be large numbers of people interacting, and they are more likely to argue.”

Perhaps the realization that there is a link will help people in an argument step back and say, “Let’s cool off” － both literally (字面上地) and figuratively (比喻地).
