called a California condor (大秃鹫) is flying overhead. Who is this man, and why is he so important that he is
featured (处于显著地位) on the back of a coin?
The man on this quarter is John Muir. Even as a child, Muir loved watching nature. As a young man, he
spent much of his life exploring the beauty of the wilderness. He walked more than a thousand miles across
the country, through fields and woods. John Muir liked writing about the places he visited, describing their
beauty.
Muir also wrote about problems.In order to create more farmland for sheep and cattle, rnany trees were
being cut down.This made Muir unhappy and worried, because he knew that trees were important to forests
and to the animals that lived in them.
Muir believed that nature should be conserved (保护) instead of being changed by human beings.He wrote
articles in magazines and newspapers to spread the word about conserving forests.Soon, others began to
listen. Muir wrote letters to important people,such as President Theodore Roosevelt. The president admired
Muir's love for nature.When Roosevelt came to visit Muir in California. Muir convinced (说服) the president to
go camping with him for three nights under the trees so they could talk about conservation. Later,President
Roosevelt set aside 148 million acres of land for national forests and established (建立) five national parks.
National parks are large areas of land that are protected from development. This means that people cannot build
homes or businesses there. One of these parks is Yosemite National Park,the area that is featured on the back
of the California quarter.
Though it has been almost one hundred years since John Muir died,people continue his work today. His

If you are cycling in foreign countries, you will need to know what these traffic signs and signals mean.
1 | A sign like this one means that there is a bike lane(车道). If there is such a sign,you are required to use the bike lane. If there is not such a sign, you should ride with traffic as far to the right side of the road as possible. | |
2 | This signal means you can cross the street along with pedestrians(行人). It has a green picture of a oerson walking instead of using the word“walk”. | |
3 | This signal is the “don’t walk”sign. It is a picture of a red hand, meaning you should stop. You should wait to cross the street until the green picture of the person walking is showing. | |
4 | Car drivers and bikers must come to a complete stop at“STOP” signs. | |
5 | A“YIELD”sign means to slow down and be ready to stop. If there are pedestrians or vehicles in or near the crossroad, you must stop. If there is no traffic in or near the crossroad and it is safe, you may go through. | |
6 | This signal means you are coming to a zebra crossing. Car drivers and bikers must stop to allow people in the zebra crossing to cross the street. | |
7 | When people are working on the roads, parts of the road are often dug up or rough(不平整的). Be careful when yon are cycling. Rough roads could make you fall off your bike.

A sign is another kind of language. Here are some of them that you see on the roads.
Number One is a sign with the number thirty on it. When drivers see this sign, they must not go at more than thirty kilometers an hour. We see this sign when we are getting near a town. Number Two is a sign that we’re near a crossing. We must drive carefully. Number Three is a sign that there is a bend (拐弯) in the road. Again, we must drive slowly and carefully. It is not safe to go around a bend very fast. Number Four is a sign that there is another road coming in from the right. There is a junction (交叉) at this place. Number Five is a sign that there is a hill and Number Six is a sign that the road gets narrow. Drivers must go slowly and carefully. Number Seven has the word “SCHOOL” on it. This is a sign that there is a school at the side of the street or the road. Perhaps there are children going to or leaving school. So drivers must look carefully and go slowly. Number Eight is a sign with the letter “P” on it. The letter “P” means “Parking”. At some places, there are the signs “No parking” or “No waiting”. If a driver leaves his car near one of these signs, a policeman may come and write down the number of his car.
