The Healthy Habits Survey shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.
1. How many times did you brush your teeth yesterday?
Finding: A full 3% of seniors brush their teeth only once a day
Step: Remove the 300 types of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes at least twice a day.
2. How many times did you wash your hands or bathe yesterday?
Finding: Seniors, on average, bathe fewer than 3 days a week. And nearly 30% wash their hands only 4 times a day—half of the number doctors recommend.
Step: We touch our faces around 3,000 times a day—often inviting germs（病菌）to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most importantly, wash your hands often with hot running water and soap for 20 seconds.
3. How often do you think about fighting germs?
Finding: Seniors are not fighting germs as well as they should.
Step: Be aware of germs. Do you know it is not your toilet but your kitchen sponge（海绵）that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.

Sometimes known as “The Big Apple” or “the City That Never Sleeps”, New York is both the most populous city in the USA and a leading center of business, commerce, finance and media. The city is often referred to as “New York City”, in order to distinguish it from the state it is in. The city is part of a large metropolitan（大都市的）area, and the combined city population exceeds 18.7 million.
New York City is made up of five boroughs（行政区）and hence another nickname of the city is “The Five Boroughs”. The five boroughs are: The Bronx, Brooklyn, Manhattan, Queens and Staten Island.
There are many famous buildings and sights in New York, especially in Manhattan. These include the Empire State Building, the Flatiron Building and the United Nations Building. When you visit New York, make sure you see Central Park, Times Square, Chinatown, Little Italy and of course the Statue of Liberty. Additionally, there are many wonderful museums in New York, some truly excellent shops, some of the world’s best theaters in the Broadway area, and the neighborhoods of Greenwich Village and SoHo which are well-known for the artists who reside there.
Getting around New York City is simple—the city’s subway network is one of the most comprehensive in the world, connecting all parts of Manhattan in rapid time.
However, the best way to see New York is undoubtedly on foot. Central Park is an ideal place to start a walking tour of New York City—843 acres of shining ponds and lush greenery attract locals and tourists. And apart from offering breathtaking scenery, it is a centre for recreation. Visitors can listen to music groups, watch performers, walk along the trails and even take a romantic ride in a horse carriage.

Are you carrying too much on your back at your back at school? I’m sure lots of children of your age will say “Yes”. Not only the students in China have this problem, but children in the United States also have heavy school bags.
Doctors are starting to worry that younger and younger students are having back and neck problems as a result of school bags being too heavy for them.
“It’s hard for me to go upstairs with my bag because it’s so heavy,” said Rick Hammond, an 11-year-old student in the US.
Rick is among students who have common school bags with two straps（带子）to carry them, but many other students choose rolling（有滚轮的）bags.
But even with rolling bags, getting up stairs and buses is still a problem for children. Many of them have hurt their backs and necks because of the heavy school bags.
But how much is too much? Doctors say students should carry no more than 10% to 15% of their own body weight.
Scout Batch, a back doctor, said children under Grade 4 should stay with 10%. But it is also important that older children don’t stay with over 15%, because their bodies are still growing.
“Children are losing their balance and falling down with their school bags,” he said.
Parents and teachers are starting to tell children to only take home library books they will be reading that night. Some teachers are using pieces of paper or thin workbooks for students to take home.
One of the best answers is, as some children said, to have no homework at all!

Did you ever notice your shadow at different times of the day? Shadows change as the day goes on.
In the morning the sun makes long shadows. In the middle of the day, the sun seems to be right over your head and your shadow is very, very small. As the sun goes down in the afternoon, shadows grow very long again. But the long afternoon shadows fall in a different direction from the long morning shadows.
Long, long ago people told time by the shadows. Put a piece of paper in the sunlight. Stand a pencil in a spool in the middle of the paper. The shadow of the pencil will fall on the paper and move as the day goes on. Use a watch and every hour marks the place where the shadow falls. Now your paper is a sundial（通过太阳辨别时间的日规）and you can tell every sunny day. Just look at your paper sundial and see where the shadow falls.
