Food safety is a problem in all places around the world and people in different areas of the world prepare foods in different ways. The WHO released five simple rules for preparing food in a safe way. 1.
Key 1: Keep clean.
The first key tells about the importance of washing. People should wash their hands often—before touching food, while they are preparing food, and any time after they go to the toilet. People should wash all surfaces and equipment used for preparing food. 2.
Key 2: 3.
People should separate raw, or uncooked food from foods that are already cooked and foods that will not be cooked. People should store raw meat, chicken, and fish in containers, or in separate areas. Raw foods should not touch prepared foods.
Key 3: Cook completely.
People should cook eggs and meat, like birds, seafood, and animals, especially carefully. These foods may carry more micro-organisms than other foods. Food like soup must be boiled for at least a minute to make it be cooked completely. It is also important that people re-heat cooked food completely.
Key 4: Keep food at safe temperatures.
When people are finished with eating, they should keep the left food in a refrigerator below 5℃ and shouldn’t store it for too long. At room temperature, about 20℃, the amount of micro-organisms can increase very quickly. 4. They cannot grow as quickly in a very hot or very cold environment.
Key 5: Use safe water and raw materials.
5. Damaged or old food may develop harmful chemicals as it gets older.
A.Eat cooked food immediately, while it is still hot.
B.They call these rules the “Five Keys to Safer Food.”
C.Separate raw and cooked.
D.People should use safe water and choose fresh foods.
E.Keeping everything clean helps people to avoid micro-organisms.
F.People should also protect cooking areas and food from insects and animals.
G.But temperatures above 60℃ or below 5℃ control the growth of micro-organisms.
Getting older is a natural part of life. Changes as you get older are usually gradual. Certain physical changes are common. How fast your body can burn calories slows over time, which means that your body needs less food energy than before.
How much and how well you sleep will likely change. Most people start needing reading glasses around forty, and many have some hearing loss later in life. Starting in your fifties, bone aging increase. How you feel as you get older depends on many things, including what health problems run in your family and the choices you make.
If your family members have diseases or chronic (慢性的) health problems like high blood pressure, then you may have a greater chance of having those problems yourself. But it doesn’t mean you will definitely have the same problems. Actually, the lifestyle choices you make can help reduce your chances of getting illness that run in your family. And even if you do get a family illness, choosing to be physically active, to eat healthy foods, and to learn how to deal with stress can keep the illness from destroying your ability to enjoy your golden years.
What do you need to do to feel your best as you age? One of the most important things you can do for your health at any age is to be physically active. Physical activity keeps your body strong, and it helps with how you feel. People who stay active are less likely to get depressed.
Your mental and emotional health is also important. Protect or improve your emotional health by staying in touch with friends, family, and the community. People who feel connected to others are more likely to feel happy than those who do not.

Do you drink water that's been left sitting out overnight or even for another day? Have you noticed it tastes different?
Tap water that has been left to sit out slowly begins to acquire(获得) off taste. Many people think that this is because of microorganisms. But that's not what makes old water taste not fresh. For that we can thank carbon dioxide. After about 12 hours, tap water starts to go flat as carbon dioxide in the air starts to mix with the water in the glass, lowering its PH and giving it an off taste. But it's most likely safe to drink.
However, back to those microorganisms. If you use a dirty glass day after day, there is more of a chance of bacteria making themselves known; a risk that increases if you share the glass with another mouth as well. But assuming(假设) you use a fresh glass every few days, you probably won't have a problem unless the glass has been touched by dirty fingers, and especially if those dirty fingers went unwashed after using the bathroom.[
As for plastic water bottles that have been left out in the sun or in the car, step away from the bottle, warns Dr. Kellogg Schwab, director of the Johns Hopkins University Water Institute. "A chemical called biphenyl-A, or BPA, along with other things used to make plastic can leach(过滤) into your water if the bottle heats up or sits in the sun," he explains. BPA, as you probably know, has been linked to everything from heart disease to cancer. Schwab also adds that plastic used for commercial bottled water isn't meant to be washed or refilled, so use only one time and recycle. Or don't buy them at all; use refillable water bottles instead.
1.Tap water begin to acquire an off taste because of______ .
A. carbon dioxide B. BPA
C. the glass D. the microorganism
2.According to Paragraph 2, tap water that's been left sitting out for 12 hours____.
A. contains few microorganisms B. is still safe to drink
C. tastes better D. is most likely undrinkable
3.What should we do with plastic water bottles that have been left out in the sun or in the car?
A. Use them after they cool down.
B. Clean them and use them again.[来
C. Throw them away.
D. Refill them with fresh water
4.Which of the following is true about BPA?
A. It is safe for people to use.
B. It is a kind of new material.
C. It is the main material to make plastic.
