Until I started my Happiness Project, I didn’t think much about rituals and whether they made me happy. But when I reflected on them, I realized that I found rituals both calming and energizing.
For example, in my high school, exams were taken very seriously. When everyone was steeled at a desk, the teacher would pass out the papers, and we would lay them face down. She would return to the front of the classroom, look at the clock, and say quietly, “It is 9:10 now. You have two hours. Be sure to read all the instructions carefully”—then a pause —“you may turn over your test paper and begin now.” This familiar, quiet formula made the start of an exam into a little ritual that put me in the right frame of mind to face a tense exam.
In kindergarten, after singing a good-bye song, the children stand in a circle in the classroom, while the grown-ups wait in a line outside the door. The teacher calls the children’s names, one by one, and the child comes to the door to get a big hug and to leave. The orderliness of this process keeps everyone calm and cheerful.
So think about rituals in your life. Take a moment to taste the enjoyable ones. Think about opportunities to heighten the experience of an ordinary occasion by treating it with special consideration. This is particularly useful if it’s a stressful or emotional experience, discussing a child’s report card, giving a performance review. Packing for a trip, or getting ready for a date.
Studies show that family traditions and family rituals encourage children’s social development and improve feeling of family. They’re not just important for children but for the whole society.

With only about 1,000 pandas left in the world, China is desperately trying to clone(克隆)the animal and save the endangered species(物种). That's a move similar to what a Texas A & M University researchers have been undertaking for past five years in a project called “Noah's Ark”．
Noah's Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M's College of Veterinary Medicine, says there would be enough of the basic building blocks reintroduce the species in the future.
It is estimated that as many as 2,000 species of mammals, birds, reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
“The nuclear transfer(核子移植)of one species to another is not easy, and the lack of available(capable of being used)panda eggs could be a major problem，”Karemer believes. “They will probably have to do several hundred transfers to result in one pregnancy(having a baby). It takes a long time and it's difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort，” adds Kraemer, who is one of the leaders of the Project at Texas A & M, the firstever attempt at cloning a dog.
“They are trying to do something that's never been done, and this is very similar to our work in Noah's Ark. We're both trying to save animals that face extinction. I certainly appreciate their effort and there's a lot we can learn from what they are attempting to do. It's a research that is very much needed.”The aim of “Noah's Ark” project is to________.
| A．make efforts to clone the endangered pandas |
| B．save endangered animals from dying out |
| C．collect DNA of endangered animals to study |
| D．transfer the nuclear of one animal to another |
According to Professor Kraemer, the major problem in cloning pandas would be the lack of________.
| A．available panda eggs | B．host animals |
| C．qualified researchers | D．enough money |
The best title for the passage may be________.
| A．China's Success in Pandas Cloning |
| B．The First Cloned Panda in the World |
| C．Exploring the Possibility to Clone Pandas |
| D．China—the Native Place of Pandas Forever |
From the passage we know that________.
| A．Karemer and his team have succeeded in cloning a dog |
| B．scientists try to implant a panda's egg into a rabbit |
| C．Kraemer will work with Chinese scientists in clone researches |
| D．about two thousand of species will probably die out in a century |
A visit to NASA Langley Research Center would be very exciting. You could meet NASA scientists and engineers working with wind tunnels.
Wind tunnels are basically tubes through which air—or a gas—is moved to make “wind” in the tube. This “wind” moves past objects such as airplanes or just parts from airplanes.
It s always a good idea to test a new aircraft design in a wind tunnel before you build the real aircraft. Models tested in wind tunnels will always go through design changes before engineers are satisfied with its design and test results.
Wind tunnels are constructed with some very wide sections as well as some sections much smaller in size. An “open return wind tunnel”is open at both ends of the tube. It is usually largest at one end of the tube where you may even see the fan blade(风扇片)that creates the wind. This tube gets smaller as you move away from the fan blade. The tube begins to straighten in the next part of the wind tunnel called the Test Section. This is where you place the model for testing. The tube widens again as you move away from the Test Section.
Another wind tunnel is the “closed return” design. This tunnel is completely contained inside a building. The tunnel moves in a “loop” inside the building. A fan is located in the tunnel on one side of the building and the test model is located in the tunnel's Test Section on the other side of the building.
NASCAR race teams even test their race cars in wind tunnels to test and improve a car's design. These teams work hard to reduce a car's drag. In less than 150 years, wind tunnels have allowed mankind to improve cars on the ground, aircraft in the atmosphere, and spacecrafts in space. We can only imagine what will happen with wind tunnels during the next hundred years.What could be the best title of the passage?
| A．What Are Wind Tunnels Made of? |
| B．What Is a Wind Tunnel and How It Works? |
| C．Where Can Wind Tunnels Be Found? |
| D．Why Are Wind Tunnels Used? |
Which of the following is the right shape of an “open return wind tunnel”？
In the “close return” wind tunnel, the fan is fixed________.
| A．in the Test Section on the other side of the building |
| B．next to the models in the building |
| C．at one end of the opening |
| D．on the other side of the Test Section |
By reducing a race car's drag, ________.
| A．the car will becomes lighter |
| B．the car will be easy to operate |
| C．the car will move faster |
| D．the car will look more beautiful |
The private automobile(私家车)has long played an important role in the United States. In fact, it has become a necessary and important part of the American way of life. In 1986, sixty-nine percent of American families owned at least one car, and thirty-eight percent had more than one. By giving workers rapid transportation, the automobile has freed them from having to live near their place of work. This has encouraged the growth of the cities, but it has also led to traffic problems.
For farm families the automobiles is very helpful. It has made it possible for them to travel to town very often for business and for pleasure, and also to transport their children to distant schools.
Family life has been affected(影响)in various ways. The car helps to keep families together when it is used for picnics, outings, and other shared experiences. However, when teenager children have the use of the car, their parents can't keep an eye on them. There is a great danger if the driver has been drinking alcohol or taking drugs—or is “showing off” by speeding or breaking other traffic laws. Mothers of victims(受害者)of such accidents have formed an organization called MADD(Mothers Against Drunk Driving). These women want to prevent further tragedies(悲剧). These women want to prevent further tragedies(悲剧). They have worked to encourage the government to limit the youngest drinking age. Students have formed a similar organization SADD(Student Against Drunk Driving)and are spreading the same message among their friends.
For many Americans the automobile is a necessity. But for some, it is also a mark of social position and for young people, a sign of becoming an adult. Altogether, cars mean very much to Americans.Which of the following is NOT mentioned in the text?
| A．Cars have encouraged the growth of the cities. |
| B．Cars can bring families together when they go for picnics. |
| C．Cars have enabled people to live far from their place for work. |
| D．Cars help city families to transport their children to faraway schools. |
What has been done to deal with the problem of drunk driving?
| A．Parents have paid more attention to their children. |
| B．Some organizations have been set up against drunk driving. |
| C．Mothers have tried to persuade their children not to drink alcohol. |
| D．University students have asked the government to solve the problem. |
We can infer from the text that________in American.
| A．it will be more difficult for people to get new cars |
| B．parents will not allow their children to have their own cars |
| C．the government will encourage people to use public transportation |
| D．cars will still be popular though they have caused many problems |

It's 2035. You have a job, a family and you're about 40 years old! Welcome to your future life.
Getting ready for work, you pause in front of the mirror. “Turn red，” you say. Your shirt changes from sky blue to deep red. Tiny preprogrammed electronics(智能电子元件)are rearranged in your shirt to change its color. Looking into the mirror, you find it hard to believe you're 40. You look much younger. With amazing advances in medicine, people in your generation may live to be 150 years old. You're not even middle-aged!
As you go into the kitchen and prepare to pour your breakfast cereal into a bowl, you hear, “To lose weight, you shouldn't eat that，”from your shoes. They read the tiny electronic code(电子源码)on the cereal box to find out the nutrition details. You decide to listen to your shoes. “Kitchen, what can I have for breakfast？”A list of possible foods appears on the counter as the kitchen checks its food supplies.
“Ready for your trip to space？”you ask your son and daughter. In 2005 only specially trained astronauts went into space—and very few of them. Today anyone can go to space for day trips or longer vacations. Your best friend even works in space. Handing your children three strawberries each, you add, “The doctor said you need these for space travel.”Thanks to medical advances, vaccination shots(防疫针)are a thing of the past. Ordinary foods contain specific vaccines. With the berries in their mouths, the kids head for the front door.
It's time for you to go to work. Your car checks your fingerprints and unlocks the doors. “My office. Autopilot！” you command. Your car drives itself down the road and moves smoothly into traffic on the highway. You sit back and unroll your enewspaper. The latest news downloads and fills the viewer. Looking through the pages, you watch the news as video film rather than read it.What changes the color of your shirt?
| A．The mirror. |
| B．The shirt itself. |
| C．The counter. |
| D．The medicine. |
How do the shoes know that you shouldn't eat the breakfast cereal?
| A．By pouring the breakfast into a bowl. |
| B．By listening to the doctor's advice. |
| C．By testing the food supplies in the kitchen. |
| D．By checking the nutrition details of the food. |
The strawberries the children eat serve as________.
| A．breakfast |
| B．lunch |
| C．vaccines |
| D．nutrition |
How is the text organized?
| A．In order of time. |
| B．In order of frequency. |
