How can you find out what is going on inside ...

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 can show even more. They can give a complete view of body organs.

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 from each direction and produces a clear cross-sectional picture on a screen. This picture is then photo-graphed for later use. Several cross sections, taken one after another，can give clear “photos” of the entire body or of any body organs. The latest 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 than regular X-rays do. CAT scans can also be done without getting something harmful into the patient, so they are less risky than 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.

Five Questions to Ask to Detect a Lie

Are you being lied to? Find out how you can tell.

How is the person speaking?

Although a change in voice can be the tip-off to a lie, experts say that to be sure, you should also pay attention to a person’s speech rate and breathing pattern. ___1.__

What is the person saying?

Liars tend to avoid exclusionary words like “but,” “nor,” “except,” and “whereas,” because they have trouble with complex thought processes. __2.___ In their attempts to distance themselves psychologically from their tall tales, liars will tend to communicate using fewer personal pronouns.

Is his face giving it away?

You may think disguising your true feelings is easily accomplished with the help of a smile, but the expressions that flash across your face will give away what you’re really thinking—whether you know it or not. __3.___ These clues are often so difficult to detect that even trained experts have trouble discerning them.

How is the person smiling?

A smile can sometimes mask a person’s true feelings. ___4.___ You may be able to detect the emotions he or she is trying to hide—such as fear, anger, and disgust. A true smile will incorporate both a person’s lips and eyes.

___5.__

It’s more important to examine a person’s entire demeanor, as there’s no one feature that’s apt to give away a liar. Honesty is characterized by features that are in sync with one another—so besides posture, note the fit between face, body, voice, and speech.

These days, it seems like everything is going digital. You can find almost everything on the Internet.

Many people find this way of life more convenient, because they can complete their daily chores（琐事） from the comfort of their own home.

Firstly, online shopping can be far less stressful than hitting the high street shops. There are no huge crowds of people or boring long queues. With online shopping, it’s just you and your computer. It’s like you have the whole shop to yourself! Secondly, online stores don’t have opening and closing times. This is perfect for anyone with a busy schedule. If you want to, you can even place an online shopping order at three o’clock in the morning!

In the busy modern world, there are clearly many advantages to online shopping. However, in my experience, there are also several cons… With online shopping, you can’t try before you buy, and that’s a definite disadvantage for me. Often, when my new clothes arrive, I find they don’t fit very well. It’s always annoying when a dress is a little too big, or when sleeves are too short… Sometimes, the clothes are not what I was expecting. A piece of clothing might look great in photos online, but quite different in real life.

In these cases, you want to return the item, but here lies the biggest problem with online shopping. You have to pay for your order’s delivery, and for an item to be returned to the warehouse! These charges are often very expensive, which suddenly make online shopping seem a little less convenient… That’s why I don’t choose to shop online very frequently. For now, I will continue to find the time for a trip to a real shop, where I know exactly what I’m buying!

How far would you be willing to go to satisfy your need to know? Far enough to find out your possibility of dying from a terrible disease? These days that’s more than an academic question, as Tracy Smith reports in our Cover Story.

There are now more than a thousand genetic tests, for everything from baldness to breast cancer, and the list is growing. Question is, do you really want to know what might eventually kill you? For instance, Nobel Prize-winning scientist James Watson, one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer’（老年痴呆症）.

“If I tell you that you have an increased risk of getting a terrible disease, that could weigh on your mind and make you anxious, through which you see the rest of your life as you wait for that disease to hit you. It could really mess you up.” Said Dr. Robert Green, a Harvard geneticist.

“Every ache and pain,” Smith suggested, “could be understood as the beginning of the end.” “That ’s right. If you ever worried you were at risk for Alzheimer’s disease, then every time you can’t find your car in the parking lot, you think the disease has started.”

Dr. Green has been thinking about this issue for years. He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s. It was thought that people who got bad news would, for lack of a better medical term, freak out. But Green and his team found that there was “no significant difference” between how people handled good news and possibly the worst news of their lives. In fact, most people think they can handle it. People who ask for the information usually can handle the information, good or bad, said Green.

1.Which of the following is true about James Watson？

A．He doesn’t want to know his chance of getting a disease.

B．He is strongly in favor of the present genetic tests.

C．He believes genetic mapping can help cure any disease.

D．He is more likely to suffer from Alzheimer’s disease.

2.The first paragraph is meant to__________.

A．ask some questions                      B．satisfy readers’ curiosity

C．introduce the topic                      D．describe an academic fact

3.According to Paragraphs 3 and 4, if a person is at a higher genetic risk, it is__________.

A．necessary to remove his anxiety            B．impossible to hide his disease

C．better to inform him immediately           D．advisable not to let him know

4.The underlined part “freak out” in Paragraph 5 is closest in meaning to“_________”.

A．leave off          B．break down        C．drop out          D．turn away

5.The study led by Dr. Green indicates that people__________.

A．can accept some bad news                B．tend to find out the truth

C．prefer to hear good news                 D．have the right to be informed
