Passage 13 How can you find out what is going on inside a person’s body without opening the patient’s body up?Regular X rays can show a lot.CAT scans(扫描仪)can show even more.They can give a complete view of body organs(器官).
What is a CAT scan?CAT stands for a kind of machine.It is a special X-ray machine that gets a 360-degree picture of a small area of a patient’s body.
Doctors use X rays to study and determine diseases and injuries within the body.X rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed.
A CAT scanner,however,uses a group of X rays to give a cross-sectional(横截面)view of a specific part of the body.A fine group of X rays is scanned across the body and around the patient from many different directions.A computer studies the information form each direction and produces a clear cross-sectional picture on a screen.This picture is then photographed for later use.Several cross sections,taken one after another,can give clear “photos” of the entire body or of any body organs.The newest CAT scanners can even give clear pictures of active,moving organs,just as a fast-action camera can “stop the action”,giving clear pictures of what appears unclear to the eye.And because of the 360-degree pictures,CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient.
Frequent appearance before X rays can cause skin burns,cancer or other damage to the body.Yet CAT scans actually don’t cause the patient to more radiation(辐射)than regular X rays do.CAT scans can also be done without getting something harmful into the patient,so they are less risky that regular X rays.
CAT scans provide exact,detailed information.They can quickly find such a thing as bleeding inside the brain.They are helping to save lives.
Passage 16 Can we live without salt?Salt is very important to us.We need salt in our food.Animals need it,too.Most of the salt in our country comes from the sea.People dig very big pools (池塘) and let sea water in .When the sun dries (弄干) up the water,people can get salt from the ground.The salt is white,clean and beautiful.
There are a lot of salt wells (井) in Sichuan.A salt well is much like a water well.People bring the well water up to the ground and then dry it in big jars (坛子) over fire.In this way they get salt.We can also get salt from salt mines (矿).A salt mine may be found under the ground.Some years ago,people in Jiangxi found a big salt mine and soon opened it.People here need salt from other places no more.
In the northwest of our country,there are many salt lakes.Some of these lakes are very big.The salt in a big lake will be enough for our people for centuries.

Passage 13 我们如何能够在不打开病人身体的情况下,了解他的体内是什么样子呢?用常规的X光就能看到很多.而用CAT扫描仪能看到更多.这种扫描仪能够让我们看到全部的身体器官.
什么是CAT扫描仪呢?CAT代表着一种机器.这是一种特殊的X射线机器,通过它可以得到病人体内一个小范围的360°全方位图片.
医生用X光研究、诊断病人体内的疾病和伤害.用X光,医生可以发现体内异物,或拍出体内某些需要照X光的器官的照片.然而,CAT扫描仪则是通过一组X射线,得到体内某特定位置的横截面图像.这组X射线可以从病人的各个角度扫描他的身体.电脑通过分析来自各个角度的信息,在屏幕上生成一张清晰的横截面图片.这张图片会被打出做后期使用.几个截面图一个接一个连起来,就构成了整个身体或某一器官的“照片”.最新的CAT扫描仪甚至可以显示出动态的器官,就像一部快速相机可以抓拍,从而生成人眼所无法看清的图片.由于这些360°的图片,CAT扫描仪能够提供更加清晰、完整的图像,而这些图像在过去只能是在手术中,或尸体解剖中看到.
频繁的照X光可能会引起皮肤病、癌症或对人体造成其他伤害.但较之常规的X光,CAT扫描仪并不会带给病人更多辐射.CAT扫描仪还能够在不对病人造成任何副作用的情况下完成扫描,所以比起常规的X光,他们更加安全.
CAT扫描仪可以提供准确、详细的信息.像如颅内出血这种,他们可以很快就发现.他们对于挽救生命很有帮助.
Passage 16 我们的生存离得开盐吗?盐对于我们来说非常重要.我们的食物中需要盐.动物也需要盐.在我国,大部分盐来自于海洋.人们挖出很深的池塘把海水引进来.当日晒将水分蒸发掉后,人们就能从地上得到盐了.这样的盐是白色的,很干净,很美.
四川有很多盐井.盐井和水井非常相似.人们将井水打上来,倒入坛子在火上烤干,这样就能得到盐了.我们还可以从盐矿中得到盐.盐矿可能存在于地下.前几年,江西人发现了一个大盐矿,并很快把它开采了出来.那里的人就再也不需要其他地方的盐了.
在我国的西北,还有很多盐水湖.其中有些非常大.一个大湖里所含的盐足够我们人类使用好几个世纪了.
