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. In 1860, 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 genes are really messages. They’re written in the DNA with a special language.
In 1961, another two scientists found the first “word” that they could understand in that language. It shows how DNA tells the cell (细胞）to build its parts. So far, scientists have found all the words in the DNA map, but we still don’t understand what they all do. By understanding what just one “word” means, we can help to save people from several illnesses. 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.When did Mr. Mendel discover why we look the same as other people in our family?

Hi! My name is Robert and I live in Chicago. My school is called Parkside Elementary. It is Jake and Elizabeth's school too. Michael and Trevor's school is called Lincoln Middle School. In the USA many students go to elementary school between the ages of 5-10, then middle school between the ages of 11-13, and then a four year high school, and last but not least, many people go to college or vocational school. Our elementary school starts at 8:30 am and ends at 3:20 pm. We go to school on Monday through Fridays and have the weekends off.
Some of the favorite sports here in America are basketball, baseball, football, soccer, hockey, and more. But, my favorite sport is football. My favorite player in the NFL (National Football League) is Brian Urlacher of the Chicago Bears ( the Bears are my favorite team too).
Americans wear jeans, a shirt, socks, shoes, and sometimes a hat. I usually wear a baseball hat, my favorite pants, and my favorite shirt. My pants have 4 pockets on it, and my shirt has red and black stripes on it.
There is no common agreement in the west about the best method of education. Many views can be found among parents, teachers, and students.Students in elementary school stay at school for about ________days.
| A．four | B．five | C．six | D．seven |

Have you ever wondered?
1. Why do airplanes take longer to fly west than east?
It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon known as the jet (喷射) stream. The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic. The planes moving at a constant air speed thus go faster in the west-east direction when they are moving with the wind than in the opposite direction.
2. What would happen if the gravity on Earth was suddenly turned off?
Supposing we could magically turn off gravity. Would buildings and other structures (建筑物) float away? What happened would depend on how strongly the things were attached to the Earth. The Earth is moving at quite a speed, moving at over a thousand miles per hour. If you turn something around your head on a string (细绳), it goes around in a circle until you let go of the string. Then it flies off in a straight line. ‘Switching off’ gravity would be like letting go of the string. Things not attached to the Earth would fly off in a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling. Most things outside would fly off into space. What information can we get from the first passage?
| A．It is the jet stream that affects how fast airplanes fly. |
| B．Planes go slower when they are moving with the wind. |
| C．It takes more time to fly from NY to London than from London to NY. |
| D．The jet stream always blows from the east to the west across the Atlantic. |
The word “shoot” underlined in the 2nd passage probably means “__________”.
| A．send for | B．move quickly |
| C．come out | D．grow quickly |
It can be inferred that without gravity __________.
| A．buildings and other structures would float away |
| B．trees and buildings would not so easily fly off |
| C．something around your head would not float away |
| D．everything outside buildings would fly off into space |
Which of the following statements is not mentioned in the passage?
| A．It takes seven hours to travel from London to New York. |
| B．The earth is moving at a high speed |
| C．Everything on the earth will float away if there’s no gravity. |
| D．Everything not attached to the earth would fly off in a straight line. |
Where can we most probably read this text?
| A．In a research paper. |
| B．In a short story. |
| C．In a travel magazine. |
| D．In a student’s book. |
