Read the following text and choose the most suitable heading from A-F for each paragraph. There is one extra heading which you do not need.
| A. Factors that influence reactions to pollutants B. Possible sources of indoor air pollution C. Ways to identify diseases with similar symptoms D. Long-term effects after repeated exposure E. A commonly-ignored health threat F. Immediate symptoms and regular treatment |
Most people are aware that outdoor air pollution can damage their health, but many do not know that indoor air pollution can also have significant health effects. Environmental Protection Agency studies indicate that indoor levels of pollutants may be 2-5 times, and occasionally more than 100 times, higher than outdoor levels. These levels of indoor air pollutants may be of particular concern because most people spend about 90％ of their time indoors.
There are many sources of indoor air pollution in any home. These include combustion sources such as oil, gas, coal, wood, and tobacco products; building materials and furnishings as diverse as deteriorated asbestos-containing insulation, wet or damp carpet, and cabinetry or furniture made of certain pressed wood products; products for household cleaning and maintenance, personal care, or hobbies; central heating and cooling systems and humidification devices; and outdoor sources such as radon, pesticides, and outdoor air pollution.
Immediate effects may show up after a single exposure or repeated exposures. These include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue. Such immediate effects are usually short-term and treatable. Sometimes the treatment is simply eliminating the person's exposure to the source of the pollution, if it can be identified. Symptoms of some diseases, including asthma, hypersensitivity and fever, may also show up soon after exposure to some indoor air pollutants.
The likelihood of immediate reactions to indoor air pollutants depends on several factors. Age and pre-existing medical conditions are two important influences. In other cases, whether a person reacts to a pollutant depends on individual sensitivity, which varies tremendously from person to person. Some people can become sensitized to biological pollutants after repeated exposures, and it appears that some people can become sensitized to chemical pollutants as well.
Certain immediate effects are similar to those from colds or other viral diseases, so it is often difficult to determine if the symptoms are a result of exposure to indoor air pollution. For this reason, it is important to pay attention to the time and place the symptoms occur. If the symptoms fade or go away when a person is away from the home and return when the person returns, an effort should be made to identify indoor air sources that may be possible causes.

From my experience, there are three main reasons why people don’t cook more often: ability, money and time, _Money is a topic I’ll save for another day. So today I want to give you some wisdom about how to make the most of the time you spend in the kitchen. Here are three tips for great cooking on a tight schedule:
1. Think ahead. The moments when I think cooking is a pain are when I’m already hungry and there is nothing ready to eat. So think ahead of the coming week. When will you have time to cook? Do you have the right materials ready?_
2. Make your time worth it. When you do find time to cook a meal, make the most of it and save yourself time later on. Are you making one loaf of bread? It takes around the same amount of time to make more of something. So save yourself the effort for a future meal.
3. This may surprise you, but one of the best tools for making cooking worth your time is experimentation（实验）. It gives you the chance to hit upon new ideas and recipes (食谱) that can work well with your appetite (食欲) and schedule. The more you learn and the more you try, the more ability you have to take control of your food and your schedule.
Hopefully that gives you a good start. And don’t let a busy schedule discourage you from making some great changes in the way you eat and live!
| A．Understand your food better. |
| B．Make three or four instead. |
| C．Cooking is a burden for many people. |
| D．A little time planning ahead can save a lot of work later on. |
E. Ability is easily improved.
F. Let cooking and living simply be a joy rather than a burden (负担).
G. Try new things.
The cultures of the East and the West really distinguish each other a lot.
The origin of the eastern cultures is mainly from two countries: China and India. Both of the two cultures are developed by rivers-the Yellow River in China and the Hindu River in India.
When the two mother rivers gave birth to the Eastern culture, another famous culture was brought up on the Mesopotamian Plain-the Mesopotamian Civilization. This civilization later on developed into the cultures of Ancient Greece and Ancient Rome. Like the Chinese culture, the European culture also crossed waters. When the British settled down in America, their culture went with them over, the Atlantic Ocean. So the American culture doesn't distinguish from the European culture a lot。
Take the language system for example. In the East, most languages belong to the pictographic language while the Western languages are mostly based on the Latin system Other causes like human race difference counts as well. But what's more. due to the far distance and the steep .areas between the East and West, the two cultures seldom communicate until recent centuries. So they grew up totally in their own ways with almost no-interference（干扰） from the other.
The differences are everywhere. _But different cultures make the world of 21st century more colorful. The cultural gap should not be the obstacle (障碍) to the civilization of human being. It ought to be the motivation of our going farther.
| A． Let us work together to keep a variety of culture. |
| B． One important thing is to learn about other cultures. |
| C． And these two are well-known as the base of the European culture. |
| D． At the same time, some other differences add to the cultural differences. |
E This is because the culture systems are two separate systems on the whole.
F. They helped the two cultures develop for centuries and form their own styles.
G. They are obvious and affect people's ways of thinking and their views of the world.
