China's first moon rover (月球車), Yutu, set off from the lander early on December 15, several hours after the Chang'e-3 probe (探測器) soft-landed on the moon surface.
The 140 kg six-wheeled rover touched the moon surface at 4:35 a.m., leaving deep lines on the loose moon land. This was recorded by the camera on the lander and the images were sent to the earth, according to the Beijing Aerospace Control Center. After that, the rover and lander will take photos of each other and start their own science explorations.
Earlier this morning, engineers made final checks of the environment of the landing area and the situation of the probe. Yutu, reached its solar panel (光板) and started to drive slowly to the moon at 3:10 a.m.. It took Yutu nearly a whole hour to complete the simple task.
Chang'e-3 landed at the Bay of Rainbows on the moon, at 9:11 p.m. on December 14, making China the
third country in the world to carry out such a mission (執行此類任務) after the United States and Russia.
In old Chinese tales, Yutu was the white pet rabbit of Chang'e’s. The name for the rover was selected following an online survey that collected several million votes from people around the world.
The rover, 1.5 meters long with its two wings folded (折疊), 1 m in width and 1.1 m in height, is a perfect robot controlled by the command center from the earth. It will face challenges including temperature differences of more than 300℃ on the moon.

Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time: if corrected too much, he will stop talking. He notices a thousand times a day the difference between the language he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people’s. In the same way, children learning to do all the other things: they learn to do without being taught to walk, run, climb, whistle, ride a bicycle, compare their own performances with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes and correct them for himself. We do it all for him. We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to. Let him work out, with the help of other children if he wants it, what this word says, what the answer is to that problem, whether this is a good way of saying or doing this or not.
If it is a matter of right answer, as it may be in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time on such routine(常規) work? Our job should be to help the child when he tells us that he can’t find the way to get the right answer. Let the children learn what all educated persons must some day learn, how to measure their own understanding, and how to know what they know or do not know.
小題1:According to the passage, the best way for children to learn things is by ________.
A.listening to skilled people’s advice
B.asking older people many questions
C.making mistakes and having them corrected
D.doing what other people do
小題2:Which of the following does the writer think teachers should NOT do?
A.Give children correct answers.
B.Allow children to make mistakes.
C.Point out children’s mistakes to them.
D.Let children mark their own work.
小題3:According to the writer, teachers in school should ________.
A.allow children to learn from each other
B.point out children’s mistakes whenever found
C.give children more book knowledge
D.correct children’s mistakes as soon as possible
小題4:The passage suggests that learning to speak and learning to ride a bicycle are ________.
A.different from learning other skills
B.the same as learning skills
C.more important than other skills
D.not really important skills

On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could now read the whole “map” of the human body: DNA. DNA is something that everybody has, and it tells the body what to do. DNA is the reason that we look like our mother and father, 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, Gregor Mendel discovered a special reason why we look the same as other people in our family. It is because of small things named “genes” in our body. In 1953, James Watson and Francis Crick made another discovery and found out that those small parts are real messages written in the DNA with a special language.
  In 1961, Marshall Nirenberg and Johann Matthaei found a message in DNA showing how DNA tells the cell (細胞) to build its parts. Scientists have now 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 save more people from several illnesses.
  Most people hope that this will help make better medicine and help sick people. Other people worry that when people begin to know more words and find out lots of other information, we might use it in a wrong way, just to make people more attractive, or stop sick people from getting jobs. Man would have to meet a lot of trouble if DNA technology (技術) wasn’t limited (限制) in use.
小題1:When did we first know why we look like other people in our family?
A.In 1860.B.In 1953.C.In 1961.D.In 2000.
小題2:What did the two scientists first discover in 1961?
A. The “map” of DNA.                     B. A new illness. 
C. The language of DNA.                   D. A message of DNA.
小題3:What can we do if we understand some “words” of the language inside the body?
A.Make people get new jobs.
B.Make medicine for illnesses.
C.Make maps of human.
D.Make people less attractive.
小題4:What do people think about this work?
A.It can cause good or bad results.
B.It can cause only good results.
C.It can cause good results but won’t work.
D.It can cause only bad results.

If I ask you to shut your eyes and gave you a piece of apple to eat, would you be able to tell me what it is just by tasting it? Of course, you could. Your tongue is covered with tiny “taste buds” which help you know what different foods taste like. Do you know that foods would taste different if you did not have a nose? This experiment shows how important your nose is when you taste things.
What You Need:
? a friend to help
? small pieces of any food like carrot, orange, banana
? small pieces of apple, raw(生的) potato, and onion
What You Do:
There are actually three different experiments. You and your friend should take turns to try them on each other.
Experiment 1:
Have your friend close her eyes and open her mouth.
Give her a piece of the food and ask her to taste it.
Then, ask her what she thinks it is. She will probably guess correctly.
Experiment 2:
While your friend has her eyes closed, give her a piece of the raw potato. At the same time, hold a piece of apple right under her nose. Ask her to eat the potato (but don’t call it by name) and tell you what she thinks it is. She will say it is a piece of apple!
Experiment 3: (for the brave)
Take a piece of raw onion. You don’t have to close your eyes this time. Squeeze your nose closed with your other hand so that no smells can get into your nose. Now take a nibble of the onion. Surprise! As long as you hold your nose, you will not be able to taste the onion.
The Science Secret
You already know the science secret. Your nose and your tongue work together to make food taste the way it does. Your tongue, however, can taste only certain flavors like salty, bitter, sour, and sweet. All of the other “tastes” are actually “smells,” and you need your nose to “taste” them. Oh, and you might use this science secret the next time you are told to eat something you don’t like the taste of. If you hold your nose while you eat it, you won’t “taste” it at all.
小題1: According to this article, what could a reader know about food?
A.People hold their noses to eat onions.B.If you can smell potatoes, you will taste apples.
C.People need a sense of smell to taste some food.D.If you close your eyes, food will taste better.
小題2:What is the most likely reason Experiment 3 is called “for the brave”?
A.You keep your eyes open.B.You have to eat a raw onion.
C.You have to squeeze your nose.D.You do the experiment alone.
小題3:What’s the best title of the passage?
A.Your Eyes KnowsB.Your Nose Knows
C.Your Mouth KnowsD.Your Tongue Knows

We all know that smoking is bad for people’s health. But not many people know about the danger of secondhand smoke.
Secondhand smoke is the smoke that comes from the smoker’s breath(呼吸). If people breathe in secondhand smoke from time to time, they could get sick from it.
But how serious is the problem of the secondhand smoke? The World Health Organization(WHO) did a study of 194 countries. They found that secondhand smoke causes about 600,000 deaths every year. That is about 1% of the world’s deaths.
Secondhand smoke is especially bad for children because their bodies are still growing. According to the study, around 165,000 children under the age of 5 die each year because of secondhand smoke. Most of these deaths happen in Africa and southern Asia.
You can do something to keep yourself and other people away from secondhand smoke. You can ask the smokers, such as your parents, to smoke outside. And, if someone smokes close to you, you’d better hold your breath or just walk away.
