阅读理解。    You are made of seventy-three percent water. You have 206 bones. There are more sweat glands (汗腺) in
your feet than in any other part of your body. There are about sixty muscles in your face; you use twenty of
them to smile but forty to frown (皱眉). Your heart beats over 100,000 times each day. You are really amazing!
    The human body is a complex machine. From the day we are born our bodies grow and change because of
our environment, diet and habits. The body has many different organ (器官) systems and parts that work
together to allow us to breathe, move, see, talk, and eat food all at the same time. Most of the time we are
unaware (预兆) of what is happening in our bodies; usually it"s only when we get sick or feel pain that we
notice.
    Many people do not take enough care of their complex machines. Bad habits like smoking, drinking too much
alcohol (酒精), and eating junk food damage our bodies. Stress can also cause health problems. People who
worry a lot or have busy jobs often don"t get enough sleep, or don"t eat properly. We also damage our bodies by
playing sports or having accidents. In 1999, Americans made more than 102,000,000 visits to emergency rooms.
The two most common reasons were for injure (伤害) and poisoning. ER patients were also treated for many
other medical problems-from bad cuts and broken bones to serious illness that needed surgery (外科手术).
    As with any machine, the better you take care of it, the longer it will last. Of course, the best way to take
care of your amazing machine is to eat the right food, do regular exercise, and get enough sleep. Oh, and don"t
forget to smile! 1. What percentage of muscles in your face can be used to smile? [     ]
A. A quarter.
B. One-third.
C. Three quarters.
D. Two-thirds. 2. Some factors (因素) may cause health problems except             . [     ]
A. bad habits
B. playing sports or having accidents

From then on, people have been supposed to use cloth bags and shopping baskets instead of plastic bags in order to protect our environment. Now more and more people have realized the importance of using the cloth bags and the shopping baskets. For one thing it can protect our environment, for another it can also make our country cleaner and more beautiful. Yet we have much more things to do to solve the problem of "white pollution"!

Do you still get free plastic bags from the supermarkets? Things have changed. China has banned (禁止) free plastic bags at shops and supermarkets, and people have to pay for using plastic bags. The rule started on June 1. It came because our country tried to make litter less. Making super-thin (超薄) plastic bags has also been banned.
