So how does it work? First you have to sign up to the scheme to be sent a key. The key will unlock one of the bikes, which are kept at docking stations in and around central London. You have to pay an access fee for the key and then you pay as you go, for the length of time you use the bike.
Transport for London, which runs the scheme, is hoping to have 6,000 bikes and 400 docking stations in place by the end of the year. The new hire system is hoping to ease congestion (拥挤) in London and is expected to create up to 40 ,000 extra cycle trips a day into the city centre. London Mayor Boris Johnston launched the scheme and said London had been 6ifilled with thousands of gleaming machines that will transform the look and feel of our streets and become as commonplace on our roads as black cabs and red buses".
However, there have been a few problems since the scheme was launched last Friday. On the first day some people found they couldn't dock their bike properly and their usage of the bike had not registered. Transport for London did admit they had been expecting a few "teething problems" and have said they wouldn't charge for the first day as a "gesture of goodwill". Some other people have criticized the lack of docking stations and locks for the bikes as well as the price it costs to hire the bicycles.
Despite the comments, the green-thinking London Mayor still seems very positive about things, saying, "My campaign for the capital to become the greatest big cycling city in the world has taken a big pedal-powered push forwards. "

2 . Suppose that we lined up our roughly 14 million United States businesses in order of size, starting with the smallest, along an imaginary road from San Francisco to New York. There will be 4,500 businesses to the mile, or a little less than one per foot. Suppose further that we planted a flag each business. The height of the flag pole represents the yearly volume of sales (销量) , each $ 10, 000 in sales in shown by one foot of pole.
The line of flagpoles is a very interesting sight. From San Francisco to about Reno, it is almost unnoticeable, a row of poles about a foot high. From Reno eastward the poles increase in height until, near Columbus, Ohio - about four - fifths of the way across the nation - flags fly about 10 feet in the air.
But as we approach the eastern terminus (终点) , the poles suddenly begin to mount (升高) . There are about 300, 000 firms in the country with sales over $ 500, 000. These firms take up the last 75 miles of the 3,000 - mile road. There are 200, 000 firms with sales over $ 1 million. They take up the last 50 miles. Then there are 1, 000 firms with sales of $ 50, 000, 000 or more. They take up the last quarter of a mile before the city limits, flags flying at cloud height, 5 , 000 feet up .
At the very gate of New York, on the last 100 feet of the last mile , we find the 100 largest industrial firms . They have sales of at least $ 1.5 billion, so that their flags are already miles high. Along the last 10 feet of road , there are 10 largest companies . Their sales are roughly $ 10 billion and up : their flags fly 190 miles in the air , almost in the stratosphere (平流层) .

When Chekhov entered the Moscow University Medical School in 1879, he started to publish hundreds of comic short stories to support his family．After he graduated, he wrote regularly for a local daily newspaper．
As a writer he was extremely fast, often producing a short story in an hour or less．Chekhov’s medical and science experience can be seen through the indifference (冷漠) many of his characters show to tragic events．In 1892, he became a full time writer and published some of his most memorable stories．
Chekhov often wrote about the sufferings of life in small town Russia．Tragic events control his characters who are filled with feelings of hopelessness and despair．
It is often said that nothing happens in Chekhov’s stories and plays．He made up for this with his exciting technique for developing drama within his characters．Chekhov’s work combined the calm attitude of a scientist and doctor with the sensitivity(敏感) of an artist．
Some of Chekhov's works were translated into Chinese as early as the 1940s．One of his famous stories, The Man in a Shell, about a school teacher’s extraordinarily orderly life, was selected as a text for Chinese senior students．

It’s kind of silly to talk about the moment when pizza was “invented”. It gradually evolved over the years, but one thing’s for certain—it’s been around for a very long time. The idea of using pieces of flat, round bread as plates came from the Greeks. They called them ‘plakuntos’and ate them with various simple toppings such as oil, garlic, onions, and herbs. The Romans enjoyed eating something similar and called it ‘picea’. By about 1000 a.d. in the city of Naples, ‘picea’ had become ‘pizza’ and people were experimenting with more toppings: cheese, ham, anchovies, and finally the tomato, brought to Italy from Mexico and Peru in the sixteenth century. Naples became the pizza capital of the world. In 1889, King UmbertoⅠand Queen Margherita heard about pizza and asked to try it. They invited pizza maker, Raffele Esposito, to make it for them. He decided to make the pizza like the Italian flag, so he used red tomatoes, white mozzarella cheese, and green basil leaves. The Queen loved it and the new pizza was named ‘Pizza Margherita’ in her honour.
Pizza migrated to America with the Italians at the end of the nineteenth century. The first pizzeria in the United States was opened in 1905 at 53 Spring Street, New York City, by Gennaro Lombardi. But the popularity of pizza really exploded when American soldiers returned from Italy after World WarⅡ and raved about ‘that great Italian dish’. Americans are now the greatest producers and consumers of pizza in the world.

Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis (光合作用)．Now researchers have found a way to imitate this seemingly simple process.
The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip with catalysts (催化剂)．Similar to natural leaves，it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell，which uses those two materials to produce electricity，located either on top of a house or beside the house.
Though the leaf is only about the shape of a poker card，scientists claimed that it is promising to be an inexpensive source of electricity in developing countries. “One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology,” said Nocera at a conference of the American Chemical Society.
The artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but was too expensive and unstable for practical use. The new leaf，by contrast，is made of cheap materials，easy to use and highly stable. In laboratory studies，Nocera showed that an artificial leaf prototype (原型) could operate continuously for at least 45 hours without a drop in activity.
The wonderful improvements come from Nocera's recent discovery of several powerful，new and inexpensive catalysts. These catalysts make the energy transformation inside the leaf more efficient with water and sunlight. Right now，the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides，the device can run in whatever water is available；that is，it doesn't need pure water. This is important for some countries that don't have access to pure water.
With the goal to “make each home its own power station” and “give energy to the poor”，scientists believe that the new technology could be widely used in developing countries，especially in India and rural China.

6 . The audience starts to scream and young people all over Britain turn on their TVs. Yes, it’s Top of the Pops!
Top of the Pops is an amazing 34 years old. Pop stars from all over the world appear on this successful TV programme. After 1,800 shows, it’s still the most popular pop music show in Britain. So what’s the secret?
“We get lots of bands to perform live in the studio,” says producer Chris Cowey. “That just doesn’t happen on other shows.”
Chris starts planning the programme over a week before it goes out. His first job is to decide which bands to have on the show. When the chart of the top twenty songs is produced on Sunday, Chris can start to book the bands.
Monday starts with Chris meeting his sound, lighting and camera workers. They listen to each song and plan the show.
Tuesday is paperwork day. There are bookings to make sure of letters to answer and lots of phone calls to make. The show is on Thursday. Bands arrive at the studio from 10 o'clock in the morning and start practising. Tonight’s presenter, Jo Whiley, practices too.
First the bands go to make up. Judy and Issy are the make-up artists. “We see the stars with no make-up on, looking terrible,” says Issy. Then the bands go to the costume department where Marianne dresses the stars.
Back in the studio things are happening. The audience are practicing their dance moves! It takes over two hours to record the whole programme, then Chris edits it all night long. The final version is exactly 29 minutes long.

7 . TUVALU, a tiny country in the Pacific Ocean, has asked for help as it will be swallowed up by the sea.
Storms and huge waves are a constant threat and none of Tuvalu’s nine little islands is more than five meters above sea level. Salt water is already entering the country’s drinking water supply, as well as damaging plants that produce fruit and vegetable. Without urgent help, the country’s days are numbered.
But Tuvalu is not the first place to face sinking into the sea. Venice, a historic city in Italy best known for its canals, has sunk about 24cm over the past 100 years. Experts say that it will have sunk another 20-50cm by 2050. A century ago, St. Mark’s Square, the lowest point city, flooded about nine times a year. Nowadays, it happens more than 100 times. While Venice is slowly sinking into the mud on which it stands, global warming causes Tuvalu’s rising sea level.
The average global temperature has increased by almost 0.5 centigrade degrees over the past century; scientists expect it rise by extra 1-3 degrees over the next 100 years.
Warmer weather makes glaciers (冰川) melt, and adds more water to the ocean. The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen about 10-25 cm in the last 100 years.
The main cause of global warming is human pollution. Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2. This adds to the power of the greenhouse effect, making the planet even warmer.
Many scientists believe that, if the warming is not stopped, there will be huge climate changes. The sea level could rise by one meter this century.
Should this come true, the sea will swallow up millions of homes and the world will be flooded with “climate refugees” looking for somewhere to live.
