What is a creepy crawly?
A few years ago, I was on a bicycle trip when I got off my bike for a rest. I sat down on the grass. A few seconds later, I was covered in ants. They were swarming all over me so I got up and brushed them off. It was a strange experience but I soon forgot about it.
A couple of years later, I was living in Jordan. I had just moved into a modern flat and was unpacking plates when I saw something move out of the corner of my eye. I looked over at the kitchen drawer and there was a cockroach crawling out of it. I screamed. Then I grabbed a can of insecticide and sprayed it on the cockroach. He ran under the nearby bathroom door. It took me three days before I found the courage to open the bathroom door to see if he was still alive. He wasn’t.
Why did I react so violently to one lone insect when a closer encounter with hundreds of ants hardly affected me? The answer is easy: because cockroaches are creepy crawlies and ants aren’t. Creepy crawlies are those little bugs which provoke feelings such as uneasiness, anxiety or dislike – they make your skin crawl.
Did you know that some people feel such a fear of bugs that it becomes a phobia? Psychologists have offered many explanations. Some say we associate them with dirt and disease. Or that these are life forms that are so alien to us, that we find them repulsive(令人厌恶的) for their dissimilarity.
Insects, however, don’t follow our rules – they just do what they want and invade our space. Unfortunately, although insects and bugs have been a successful animal species up to now, many of them, like many other species nowadays, are under threat of extinction. Entomologists warn that this could upset entire ecosystems and lead to all kinds of disastrous consequences.
So my plea to you is: the next time you feel the urge to stamp on, splatter or spray a creepy crawly, give a thought to the planet and stop.

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 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 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.

What is a dream?
For centuries, people have wondered about the strange places that they seem to visit in their sleep. 1 However, they have been valued as necessary to a person's health and happiness.
Historically people thought dreams contained messages from God. It was only in the twentieth century that people started to study dreams scientifically believing that they tell about a person's character. 2 He believed that dreams allow a person to express fantasies or fears, which would be socially unacceptable in real life.
The second theory to become popular was Carl Jung's compensation theory. Jung, a former student of Freud, said that the purpose of a dream is not to hide something, but rather to communicate it to the dreamer. 3 Thus, people who think too highly of themselves may dream about falling; those who think too little of themselves dream of being heroes.
Using more recent research, William Domhoff from the University of California found that dreaming is a mental skill that needs time to develop in humans. , 4 Until they reach age five, they can not express very well what their dreams are about. Once people become adults, there is little or no change in their dreams. The dreams of men and women differ. For instance,
The characters that appear in the dreams of men are often other men, and often involve physical aggression.
The meaning of dreams continues to be difficult to understand. 5 If you dream that a loved one is going to die, do not panic. The dream may have meaning, but it does not mean that your loved one is going to die.
A.Dreams make up for what is lacking in waking life. |
B.However, people should not take their dreams as reality. |
C.They have been considered as meaningless nighttime journeys. |
D.It gives scientists chances to better understand human mind. |
F.They think their mind is trying to tell them something.
G.First, there was Sigmund Freud’s theory.
