A sign is another kind of language.Here are some of them that you see on the roads.
Number 1 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 2 is a sign that we're near a crossing.We must drive carefully.
Number 3 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 4 is a sign that there is another road coming in from the right.There is a junction(交叉)at this place.
Number 5 is a sign that there is a hill.
Number 6 is a sign that the road gets narrow.Drivers must go slowly and carefully.
Number 7 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 8 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.

According to Paragraph 2, drivers see Sign 1 when they are ________.
French doctors and American scientists have reported doing an operation in which the doctor was outside the operating room.This kind of operation is known as robotic operation.
Doctor Marescaux did the operation in an office in New York City last month, while a sixty-eight-year-old woman patient was in a hospital in Strasbourg, France.
A doctor in Strasbourg got the patient ready.He placed medical tools and a small video camera in her stomach area.Doctor Marescaux in New York watched the patient on a video screen.Then he used the computer to send messages to the robot machine.The robot moved the tools that cut the woman’s gallbladder(胆囊)away.The woman got well soon after the operation and left the hospital two days later.
Experts say the main problem with such a robotic operation is based on high-speed telecommunications between the doctor and the robot.Technology must be able to send a doctor’s order to a robot to move the tools quickly.
Experts also say a successful robotic operation will improve an operation.For example, the robot can make much smaller movements than a person can.A robot machine can turn tools in ways that a doctor’s hand cannot.
Doctors say such a robotic operation will make possible safer and better operations in the future.They say it will improve doctor training.It will also mean that doctors could do an operation on people in dangerous places far away.And it could mean that people could have operations done by top doctors without having to travel to the city where doctors work.

(4)

We have just returned from our holiday.we went with our friends Edward Smith and his wife Tina to the Yorkshire Moors.This is a beautiful place.It is a natural park.There are lots of places to walk on the tops of the hills,miles of grassland with no people,just sheep and birds.
Edward,who had just come out of hospital,could not walk as far as he used to.However this meant that we walked in the mornings,and then stopped at a care for lunch,each day,before returning to the place where we lived in.Edward and I slept in front of the fire all afternoon,while the ladies went for another walk.Very pleasant!
I have taken lots of photos from the place we lived in,across the valley(峡谷) below us,ot the morning sunrise,and the mist in the valley.Also,in England,the old steam powered trains(蒸汽火车) are very popular.I have taken many photos of the train and from it.
Yesterday we had the first snow of this winter.It is very early(We usually expect snow in January).It rained all day,then snowed in the evening.Today We have bright sunshine!
Both Jenny and I are well.I don't know if I told you,in the last e-mail.that Jenny is now working in a hotel.Although she has to work hard,people there are nice and she is enjoying the work.
