American culture is unique because it is formed and developed under certain conditions. The major factors contributing to the making of this flew nation and the forming of a new culture are the hard environment, ethnic diversity (多民族) and plural religion, which is quite different from other nations in the world. What is more, these elements are still influencing the American culture.

The early immigrants who were English Puritans settled down in northeast part of America. From 1607 to 1892, frontiers were pushed further west. The frontiersmen looked for a land of rich resources and a land of promise, opportunity and freedom. Actually they looked for a better life. So individualism (个人主义), self-reliance, and equality of opportunity have perhaps been the values most closely associated with the frontier heritage (遗产) of America.

In history, people from different countries in the world rushed to America three times. They brought their own culture to America and later on, different cultures were mixed together. Thus the unique American culture is formed, a common cultural life with commonly shared values.

The fundamental American belief in individual freedom and the fight of individuals to practice their own religion is at the center of religious experience in the United States. The great diversity of ethnic backgrounds has produced religious pluralism; almost all of the religions of the world are now practiced in the United States.

Nowadays, we can see the continual influence of the three elements in the current American society. American family is typically parents and their unmarried children. Middle-aged and elderly people generally do not live with their married children. The people in America have a very strong desire to start a new life in a new place. Quite a number of people change residences every year. The average American moves fourteen times in his lifetime.

The United States is a nation of car owners. Ninety-five percent of households own a car, and 85 percent of people get to work in one. This lifestyle contributes to traffic jams on our roads and damages the environment. As autonomous vehicles begin to hit the streets over the next decade or so, it's believed that all this will change.

Autonomous vehicles will most likely decrease the number and severity of crashes, allow cars to travel more closely together and improve cooperation between vehicles, all of which tend to reduce traffic jams and increase capacity (容量).

However, this future is not certain. To realize the full potential benefits of driverless cars, we will have to act soon to encourage a culture in which transportation is shared. Many people in the automobile industry assume that driverless vehicles will automatically be shared, but there is little evidence that this is true. Most estimates suggest that driverless cars will eventually be only slightly more expensive than traditional cars, which means they'll be within reach of many consumers, so users are not willing to share rides.

If most people are going to buy into a shared-ride culture, they need to get a significant benefit. Saving a few dollars off the fare isn't likely to promote the movement significantly. A better benefit would be knowing that you're going to reach your destination more quickly. The way to make sure of quick passage is to redesign our roads to give priority to ride-sharing autonomous vehicles like building priority lanes. The cost of travel will also be varied based on how efficiently a vehicle uses the roads. Autonomous vehicles carrying more people should get higher priority than those carrying one or none at all.

Decision-makers must push for rewards that encourage the most efficient use of our limited roadway infrastructure (基础设施). The autonomous future is rapidly approaching; it is critical that we act now, while the impacts of autonomous vehicles on traffic jams and emissions are still largely within our control.

You can't always predict a heavy rain or remember your umbrella. But designer Mikhail Belyaev doesn't think that forgetting to check the weather forecast before heading out should result in you getting wet. That's why he created Lampbrella, a lamp post with its own rain-sensing umbrella.

The designer says he came up with the idea after watching people get wet on streets in Russia. "Once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy(伞蓬) built into a street lamp," he said.

The Lampbrella is a standard-looking street lamp fitted with an umbrella canopy. It has a built-in electric motor which can open or close the umbrella on demand Sensors then ensure that the umbrella offers pedestrians shelter whenever it starts raining.

In addition to the rain sensor, there's also a 360°motion sensor on the fiberglass street lamp which detects whether anyone is using the Lampbrella. After three minutes of not being used the canopy is closed.

According to the designer, the Lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lightning strike. Each Lampbrella would offer enough shelter for several people. Being installed(安装) at 2 metres off the ground, it would only be a danger for the tallest of pedestrians.

While there are no plans to take the Lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department, and insists his creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter.

Africa is a very diverse land with many different tribes. One tradition that many of these groups share is painting or marking their bodies and faces in colour. They do this for many reasons. Some marks are used to identify people as part of a group.   Let's look at some different examples of body painting.

  Among the Masai of East Africa, when men are old enough to marry and make decisions for their people, they participate in a special ceremony in which they paint their heads and faces red. This ceremony takes place every seven to fourteen years, so there is not an exact age for participating in it. The Samburu, also from East Africa, like to paint their faces and hair red because they think it looks attractive.

  To show that he has killed a lion, a man will paint his body with a natural white material, making special marks to represent this accomplishment. The Masai men also use this white to show that they are no longer boys and are considered adults.

One quite unusual example of face painting is done by the Wodaabe people of West Africa. Once a year, they have a beauty contest for men.  Then they add white and black circles and lines. Black paint is used near the eyes and on the lips to draw attention to the whiteness of their eyes and teeth, which the Wodaabe consider most beautiful.

As you travel, enjoy the beautiful and bright colours of Africa.

A. Red is the common colour in body painting because it often represents health and long life.

B. Other marks are used for ceremonies such as weddings and during times of war.

C. The ceremony expresses hope for rain.

D. The Masai men also have a unique way of showing that they are brave.

E. The women then decide which man they like best.

F. The men pretend to fight each other.

G. The men paint their faces yellow and red.

With the expanding of cities, the (grow) of population and reduction of agricultural land cause a great challenge to food supply. Planting hybrid rice is the most effective way (increase) crop yield per unit area. "Father of Hybrid Rice" Yuan Longping has made enormous (contribution) to the development of high-yielding hybrid rice.

China is currently one of the world's largest food producing countries. However, in the 1960s, when young Yuan Longping witnessed the nation suffering severe food crisis—the destructive 3-year countrywide famine, he was stricken, (feel) sorry and determined to develop high-yielding crops for farmers. (team) up with his colleagues, Professor Yuan finally succeeded discovering natural male sterile plants, served as the beginning of his research on hybrid rice. Today, nearly 57% of rice field in China grow hybrid rice species and the increase in output can support 70 million more people (annual).

Even when Professor Yuan was in his eighties, he insisted on working on the rice field with an aim to develop even-more high-yielding and (good) quality hybrid rice for world food supply.

About eighth years ago, I went to visit my grandfather during the summer holiday, who lived in a small village. One Saturday afternoon, my grandfather asked me climb a nearby mountain with him. At first, I ran fast, leaving my grandfather behind. However, about twenty minute later, I felt so tired that I stopped run and eventually chose to sit down for a rest. Soon, my grandfather reached when I was. He looked for me and asked, "Have I noticed the beautiful flowers along the way?" I kept silently. My grandfather smiled, "My dear, you are not in a race and on a journey." After that, my grandfather and I had walked slowly, appreciating the scenery and laughing along the way.
