London's transport services offer you a special experience of the city. Here's a round-up of the transport choices available to you.

    London Underground

    There are 11 colour-coded Underground lines. Services run regularly from around 05:00 to 00:30 (Sunday 07:30 to 23:30) on most routes.

Visit tfl.gov.uk/tube for more information.

    Tip:

    Always stand on the right when using the escalators (电动扶梯) at Tube stations. It can get hot and busy on the Tube during peak (高峰) travel times, so you may prefer to travel outside these hours.

    Buses

    A cheap and easy way to travel around London. They generally run from 05:00 to 00:30. Night buses operate on many major routes from around midnight to 05:00, and some operate a 24-hour service.

    It is not possible to pay for your London bus fare in cash. Instead you can pay with a Visitor Oyster card, Oyster card, Travelcard or UK-issued contactless payment card. A single bus journey is £1.50 with an Oyster card or UK-issued contactless payment card.

    To help you get home, if you don't have enough credit on your Oyster card, you will be able to make one more bus journey.

    After this you will need to top up the credit on your card before you use it again. If your contactless payment card has been issued outside the UK, please check tfl.gov.uk/contactless before you use your card to travel on our bus services. For any international transaction fees (手续费) that may apply, please check with your card issuer.

    For more information visit tfl.gov.uk/buses.

    Tip:

    Some bus routes are especially good for sightseeing — try routes 9, 14, 15 and 22. The New Routemaster bus featured in the James Bond film Skyfall and runs on routes 9, 11, 24, 38 and 390.

    If you run out of credit on your Visitor Oyster card, it's easy to add more at:

    Touchscreen ticket machines in Tube, DLR, London Overground and some National Rail stations.

    Around 4,000 Oyster Ticket Stops cross London (Find your nearest one at ticketstoplocator.tfl.gov.uk).

    Travel & Visitor Information Centres.

    Envelope Budget

    From McDonald's to Sonic, fast food had a bad effect on my waistline and my budget. It was nothing to run to a drive-through to pick up a cold drink or a quick bite to eat. It was so easy to use my card for a small purchase. For me, I got a lot of satisfaction from fast food.

    One day I sat down and calculated that I was spending a surprising $40 a week on fast food. This was a lot of iced coffee and hamburgers! Instead of reducing my guilty pleasures, I decided to give myself a strong budget to reduce my consumption. Every Monday I placed an envelope with $20 in my purse. That was my fast food budget for the entire week. If there was anything left over at the end of the week, it was mine to save or spend. If I spent all of the money during the week, there were no more fast food stops that week.

    The budget made me more mindful of my purchases. Instead of purchasing a large drink from Sonic, I would purchase a small. It was sill satisfying but not nearly as pricey. Instead of eating a whole meal, I would pick the part that I actually wanted. Many days, the thought of hanging onto the money for a special purpose meant more to me than the instant satisfaction of fast food. I never really felt unhappy because it was a conscious choice to spend or save with each purchase.

    Envelope budget kept me honest. I had a clear idea how much money was spent each week on fast food purchases. I started to bring my lunches more often to save more money for the week. It was a fun challenge to see how much I could save every week.

    Changing the way I spent on fast food not only helped my budget, but improved my weight. In the first month I was able to get rid of 5 pounds by simply changing the way I approached spending on fast food. Now I am more likely to bring my lunch than to buy it. I am not upset, but empowered to make positive choices to improve my life.

    No poem should ever be discussed or "analyzed", until it has been read aloud by someone, teacher or student. Better still, perhaps, is the practice of reading it twice, once at the beginning of the discussion and once at the end, so the sound of the poem is the last thing one hears of it.

    All discussions of poetry are, in fact, preparations for reading it aloud, and the reading of the poem is, finally, the most telling 'interpretation' of it, suggesting tone, rhythm, and meaning all at once. Hearing a poet read the work in his or her own voice, on records or on film, is obviously a special reward. But even those aids to teaching cannot replace the student and teacher reading it or, best of all, reciting it.

    I have come to think, in fact, that time spent reading a poem aloud is much more important than "analyzing" it, if there isn't time for both. I think one of our goals as teachers of English is to have students love poetry. Poetry is "a criticism of life", "a heightening of life, enjoyment with others". It is "an approach to the truth of feeling", and it "can save your life". It also deserves a place in the teaching of language and literature more central than it presently occupies.

    I am not saying that every English teacher must teach poetry. Those who don't like it should not be forced to put that dislike on anyone else. But those who do teach poetry must keep in mind a few things about its essential nature, about its sound as well as its sense, and they must make room in the classroom for hearing poetry as well as thinking about it.

Chien-Shiung Wu was a Chinese-American particle and experimental physicist who made significant contributions in the fields of nuclear and particle physics. She is best known for conducting the Wu experiment, which proved that parity (对称) is not conserved. This discovery resulted in her colleagues Tsung-Dao Lee and Chen-Ning Yang winning the 1957 Nobel Prize in Physics, while Wu herself was awarded the Wolf Prize in Physics in 1978. Her expertise in experimental physics aroused comparisons to Marie Curie.

Chien-Shiung Wu was born in a town of Jiangsu province, China, in 1912. Wu and her father were extremely close, and he encouraged her interests passionately, creating an environment where she was surrounded by books, magazines, and newspapers. Wu received her elementary school education at Mingde Women's Vocational School founded by her father.

Wu left her hometown in 1923 to go to the Suzhou Women's Normal School No 2, which was fifty miles from her home. In an era when "getting married" was considered the best destiny for women, she carved out a new path for herself through her diligent and earnest approach to learning and her thirst for knowledge.

In 1936, Chien-Shiung Wu went to the United States to pursue further studies in atomic physics. It was during this period of her education that she came to know Oppenheimer, who was teaching in the Physics Department. Under the guidance of renowned physicists such as Oppenheimer, Lawrence, and Segre, Chien-Shiung, Wu successfully completed her studies and her doctoral research. Due to the highly sensitive nature of her work, the details of her research were not revealed until the end of World War II.

In 1984, Chien-Shiung Wu returned to China from the United States. At the age of 72, she made a substantial donation of $250,000 to her hometown to support its development. Later, she also became an academician of the Chinese Academy of Sciences.

In 1997, Chien-Shiung Wu passed away. Before her death, she requested to be buried in her hometown of Suzhou. Today, her tombstone in Taicang, Suzhou, bears the inscription: "She was an outstanding global citizen and a forever Chinese."

I was first going into this final day, the Junior Sled Dog Championship. We'd trained two years and wanted to beat Blake. I knelt down to pat Kenai and my hands 1 from nerves and excitement. Kenai tipped up his face to lick my chin. "You are 2 , aren't you?"

Just before the countdown started, Blake shot me a 3 grin, hands trembling too. Then I heard, "Go!" 4 I could yell "Hike!", Kenai leaped forward. The rest of the dogs 5 after. We started last. We flew down the long hill. Then we 6 a corner. I leaned to keep the sled steady. Kenai saw Blake's team before I did. His tail flew up, and he 7 . Seeing his tongue still flopping forward, I let him go all out. We closed the 8 . A bridge later, we inched closer. On the next hill, Kenai drew even with Blake's sled and then we passed it.

9 our sled hit a branch. The runners caught. I lost my 10 and fell off the sled. Witnessing the sled come to a stop, I struggled through the deep snow to Kenai. I 11 . His shoulder was bleeding.

"Kenail! No!", My voice came out a howl. Kenai 12 to stand. He looked at me, his blue eyes 13 to keep on. He would do it, too. For one frozen moment I saw myself on the winner's stand with the trophy. But no, I bent and gently 14 Kenai in a blanket.

The race vet examining Kenai, I watched Blake accept the trophy. Kenai squirming (扭动) in my lap, I leaned over upon him. Just at that moment, I felt a warm tongue on my wet cheek. I smiled and realized that I had the 15 that really counted.
