题目内容
There have been many important developments in medicine．The following are two developments that have been very important in saving lives．
Imagine having an operation and being wide awake．This won’t happen，thanks to something called anesthetic．Anesthetics are given to people during operations so that they fall asleep．Anesthetics cause the muscles to relax and the body to become numb（lose all feeling）so that no pain is felt．This helps the doctors to operate more easily．Anesthetics may be taken in different ways：
●Breathing in a gas
●An injection straight into the bloodstream
●Swallowing a tablet
A local anesthetic numbs only the area where the doctor needs to work．A general anesthetic is when a Patient is put into sleep while the doctor operates Anesthetics were first given in 1844．
Heart disease is one of the biggest killers in the world today Luckily，something can be done about it．Someone who has an unhealthy heart can have a heart transport operation．A heart transplant is when the damaged heart of a patient is taken out and a healthy heart is put in．It is said，though，that the healthy heart has to come from someone who has died Doctor Barard from South Africa was the first person to do a heart transplant operation in 1967．Many successful transplants have been done since then．
It is wonderful what doctors are able to do for us．
（ ）1．With the help of______，patients aren’t able to feel painful during the operations．
A．injections B．pills C．gas D．anesthetics
（ ）2．Anesthetics have been used for about______．
A．200 B．184 C．165 D．41
（ ）3．Which does a doctor use to do a heart transplant operation to save lives，a damaged heart or a healthy heart?

新非凡教辅冲刺100分系列答案Dear Linda,
I have been in England three months now, and it’s my first time to be here. I hope you don't think I've forgotten you. There have been so many places to see and so many things to do that I've not had much time for writing letters.
I shall soon be starting my studies at King's College. So far I've been learning about England and British ways of living. I won't tell you about London. There are plenty of books you can read and plenty of pictures you can look at. I'm sure you'll be more interested to know what I think about the life here.
I find some of the customs (风俗) new and interesting. People here do not shake hands as much as we do in Europe. During the first few weeks I was often surprised because people did not put out their hands when I met them. Men raise their hats to women but not to each other.
Yours
Alice

Everyone tries to get to school on time. But when bad weather gives you trouble, can you still make it before the bell rings?
In northern China during spring, big sandstorms often make trouble for students and everyone else. When the sky is dark with sand, buses and cars all move much more slowly. Sometimes, people can’t even see for 20 metres.
Sandstorms usually happen in spring. This year, sandstorms started in late March. They have happened in more than 10 provinces (省) in northern China this year. More than 70 million people have had problems in those places because of the sandstorms.
People in southern China don’t have to worry about this kind of bad weather. Most of the sand comes from Gansu and Inner Mongolia（内蒙古）. In northern China, lots of places have few trees and don’t get much rain. People there have been cutting down too many trees. When there aren’t many trees, the ground can’t keep enough water. Over the years, the ground dries up and turns to sand. When spring comes and the ice melts（融化）, the ground becomes looser（更松散的）. Strong winds take the loose sand into the sky.
Sandstorms are bad for people’s health. If people breathe（呼吸） too much sand, they could cough or have asthma（哮喘）.
Sandstorms also give farmers lots of problems. Sometimes their sheep get lost in the storms and never get back home. The winds also tear down farmers’ houses.
What can you do to stop sandstorms? Here’s an idea: Ask you parents to help you plant some trees this spring.
If you see people cutting down too many trees, tell them about the dangers of sandstorms, and ask your government to stop them from cutting.
