DNA is the whole “map” of the human body. It is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own.
People have been trying to understand the human body for a long time, In1860, Mr Mendel discovered why we look the same as other people in our family. It is because of small things called “genes”(基因) in our body. In 1953, two scientists, Watson and Crick, found out that those small parts are really messages . They’re written in the DNA with a special language.
In1961, another two scientists found the first “word” that they could understand in that language. It shows how DNA tells the cell﹙細胞﹚to build its parts. So far, scientists have found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one “word ”means, we can help to save people from several illness. So the more we understand, the more doctors will be able to do.
Most people hope that this will help to make better medicine and help sick people. Other people worry that when we learn more “words” and find out more information, we will use it in the wrong way, just to make people more attractive (有吸引力的)，or stop sick people getting jobs.
【小題1】When did Mr Mendel discover why we look the same as other people in our family?
A. In 2000. B. In 1961 C. In 1953 D In 1860
【小題2】What did the two scientists find in 1961? They found_____.
| A．all the words in the DNA map |
| B．Small things called “genes” in our body |
| C．The first “word” they could understand in that language |
| D．those small parts are written in the DNA with a special language |
| A．Make better medicine. | B．Make them get jobs. |
| C．Make maps for them. | D．Make them attractive |
| A．We look like our parents because of “genes” in our body |
| B．We have understand what all the words in the DNA map do |
| C．DNA is the whole “map” of the human body. |
| D．DNA tells the cell to build its parts. |
| A．It can be only bad | B．It can be only good |

Have you ever had the strange feeling that you were being watched? You turned around and, sure enough, someone was looking right at you!
Parapsychologists (靈學家) say that humans have a natural ability to sense when someone is looking at them. To research whether such a “sixth sense” really exists, Robert Baker, a psychologist (心理學家) at the University of Kentucky, did two experiments.
In the first one, Baker sat behind unknowing people in public places and stared at the backs of their heads for 5 to 15 minutes. The subjects（受試者）were eating, drinking, reading, studying, watching TV, or working at a computer. Baker made sure that the people could not tell that he was sitting behind them during those periods. Later, when he questioned the subjects, almost all of them said they had no sense that someone was staring at them.
For the second experiment, Baker told the subjects that they would be stared at from time to time from behind in a laboratory setting. The people had to write down when they felt they were being stared at and when they weren’t. Baker found that the subjects were no better at telling when they were stared at and when they weren’t.
Baker concludes that people do not have the ability to sense when they’re being stared at. If people doubt the outcome of his two experiments, said Baker, “I suggest they repeat the experiments and see for themselves.”
【小題1】The aim of the two experiments is to ________.
| A．explain when people can have a sixth sense |
| B．show how people act while being watched in the lab |
| C．study whether humans can sense when they are stared at |
| D．prove why humans have a sixth sense |
| A．value | B．result | C．performance | D．connection |
| A．could tell when they were stared at and when they weren’t. |
| B．could tell when they were stared at but couldn’t tell when they weren’t. |
| C．couldn’t tell when they were stared at but could tell when they weren’t. |
| D．couldn’t tell when they were stared at or when they weren’t. |
| A．People are born with a sixth sense. |
| B．The experiments support parapsychologists’ idea. |
| C．The subjects do not have a sixth sense in the experiments. |
| D．People have a sixth sense in all places. |

閱讀短文，按要求完成各題。
If the eyes are the windows of the soul, then the body is the mirror of our feelings. If we are feeling great, we may give our body signals(信號). If we look at someone else’s body, we can often tell how thy are feeling by their body signals. So reading body language signals is a great tool in daily communication.
In case(假使) you don’t think that learning how to read and use body language is important, here are some numbers for you. 7% of the information we receive is from what people actually say, and 38% of the information we receive is from the tone(語氣) and the speed of their voice; while 55% of the information we receive is from their body language.
These non-verbal(非語言的) signals will help you a lot, but you still need to focus on what people are saying. If you focus too much on their body language signals, you and the person may feel uncomfortable. It is useful to be able to read people’s body language, but it is useful to learn how to send the right signals and avoid the wrong signals too. Body language may be given several interpretations. Many signals have different meanings, depending on the person and the situation. Be sure of it when you are trying to read a body language signal.
Facial expression is one of the body languages. Facial expressions are one or more movements on a person’s face, such as frowning(皺眉)，raising your eyebrows and rolling(旋轉) your eyes. Scientists say that humans have 80 muscles(肌肉) on their faces. These muscles can make 7.000 different facial expressions. These expressions can be put into six classes. They are happiness, sadness, anger, surprise, fear and disgust(厭惡)。
For example, when people think a certain food tastes disgusting, they usually make a funny face. When people are surprised, they often raise their eyebrows and open their eyes wide.
If people can read facial expressions correctly, they may be better at knowing other people’s feelings. That can help people make more friends. However, sometimes people have to be careful when reading others’ faces. It’s rude to stare at others for a long time.
