Nearly thirty years have passed since the American TV series. Friends, was shown for the first time in 1994. However, it is still making friends. Many Chinese teenagers love it. Through watching the show, they can not only learn about American culture but also improve their English.
Perhaps you haven't seen the series. It's a story of six young people. They came to New York City to find love, success, adventure and fun. Each of the characters had a different personality. However, they were able to overlook(忽略）their differences and became good friends. There was no social media at that time, but they always “liked” and supported one another. “I'll be there for you.” says the opening song, “because you're there for me, too.”
New phrases and strange pronunciation are two things that make learning English difficult So, watching TV series such as Friends is really helpful. You can write down the words and phrases you don't understand. Translate them and then imitate the pronunciation. And, to make it more fun, think about the life lessons you can learn from the show. Practice being “Friends” with your own friends.

Earth Day activities can include learning something about technology like cars that are more environmentally friendly and special houses that save energy and water．An organization called the Earth Day Network encourages people to use clean energy which doesn’t pollute the environment．Most of our energy comes from fossil fuels (化石燃料) that are found underground． Coal， oil and natural gas are examples of fossil fuels．Fossil fuels come from plants and animals that lived millions of years ago． Burning fossil fuels to create energy pollutes the air and water． Many scientists think that burning fossil fuels also increases the temperature of the earth． To reduce the use of fossil fuels． scientists are experimenting with hydrogen-powered (氢化发动的) cars． These cars don’t pollute the air like gas-powered cars．
Some scientists guess that by 2025, fossil fuels will run out．When people can no longer use gasoline， they may use fuel cells instead． Fuel cells use hydrogen to create energy． People do not need to worry about hydrogen running out， because it is renewable and replaceable．

It’s hard to believe how times have changed since the first modern Olympics were held in Athens, Greece, on 6th April 1896. Over one hundred years ago, there was very little reliance（dependence）on modern technology. There were no landing mats（海绵垫）, no stopwatches and no photo finishes. In fact, cameras and stopwatches were not used until the 1932 Olympic Games in Los Angeles, the USA.
Today technology has completely revolutionized（changed） sports. Take sports equipment（装备）for example. Starting blocks are now equipped with electronic pressure sensors（传感器）, which provide exactly correct race time and also help to catch runners who “jump the gun”. As athletes cross the finishing line, special digital cameras can also easily decide the winner. The clays of “dead heats” are gone.
Athletes have also benefited（受益） from technological developments. Body-hug-ging suits, which reduce（减少） wind drag, can help cut up to one-tenth of a second from runners’ race times. Top athletes are even provided with tailor-made sports shoes. These shoes are made to fit the athlete exactly—and there are even air compartments in the shoes that can be filled to meet each runner’s individual needs.
Technology has also changed the way that many sports are performed. Take one example—the pole vault（撑杆跳）. The inclusion of a landing mat obviously made a big difference to the vaulting style（方式）as athletes no longer needed to worry about hurting themselves as they fell. Without these worries, athletes could obviously jump higher. These days, polevaulters do not even need to worry about the crossbar as the uprights are now fitted with light-emitting diodes（LEDs） that measure（测量） how high the athlete vaulted. Technology has even been to the advantage of swimmers. New pools have been designed to reduce wave interference and sports scientists have even developed a new style of swimming that increases buoyancy and reduces drag in the water.
The increasing importance of these technological developments has led many sportsmen to suggest that the “Olympic spirit” is being lost in a rush to break records and win medals. Many developing countries say that technology has become too important in sport and that athletes from developing countries that cannot afford such technology are disadvantaged. There are no easy answers but one thing is sure—we cannot turn back time. Technology cannot go backwards.
1.How many pieces of high-tech sports equipment are mentioned in paragraph 2 and 3？
A．One. B．Two.
C．Three. D．Four.
2.The underlined phrase “dead heats” means “________”.
A．sports equipment which was out of date
B．runners who jumped the gun while running
C．diseases which killed runners in hot weather
D．races in which runners finished at the same time
3.What can be inferred from the fourth paragraph？
A．LEDs can measure the speed of swimming.
B．The pole vault was not quite safe in the past.
C．Polevaulters jump higher with landing mats.
D．New pools have changed the style of swimming.
4.The purpose of the writer in writing this article is ________.
A．to suggest we should keep up with the times
B．to show us the future of modern Olympics
C．to prove that the athletes have done better
D．to introduce high-tech sports equipment

Many people travel to different places in the world by air. Usually it takes a long time, perhaps half a day, for passengers to stay in the plane. So airlines offer passengers food. But it is common that they feel bad about food taste. Do you agree?
To solve this problem , airlines try hard to improve their food. They would like to do so because they don’t want to lose customers.
However, according to scientific research, part of the reason why plane food tastes bad is that at high altitude( 海拔 )we can not taste things as well as we do on the ground. Also scientists have found that our noses become very dry even before a plane takes off. As the plane moves up, the change in air pressure( 气压 ) reduces one third of the sensibility(感觉 )of our taste buds( 味蕾 ).So our taste buds become senseless. The sad face, however, is that our noses don’t know it.
All of these help explain why food on the plane tastes so bad. They also help explain why airlines choose to offer passengers salty and spicy( 辛辣 )food. Without doing so, the food would be tasteless.
Now there are many researches on this. According to one of them, some volunteers are asked to lie with their feet higher than their heads for weeks. And scientists write down their feelings about food taste.
Though scientists try their best, it is not as easy as they thought. Because they can’t deal with the special environment successfully, such as the change in air pressure, making food taste good is still hard for them.
1.In Paragraph2,“this problem” means _______.
A. passengers stay long in the plane
B. food on the plane tastes bad
C. passengers have no food to eat
D. food on the plane is expensive
2.Why do scientists feel it hard to made food on the plane taste good?
A. The volunteers don’t know about food taste.
B. The volunteers don’t understand them.
C. They can’t find enough volunteers.
D. They can’t deal with the special environment successfully.
3.What is the best title of the passage?
A. Taste of Airplane Food
B. Airplane Travel
C. Scientific Research on Noses
D. The Change in Air Pressure.
