    Hi, everyone, I'm Jane. Two years ago, my husband bought me a bicycle. If you live in a town, it is often faster than a car and you don’t have to worry about parking. You can leave it anywhere. As it has a seat at the back and a basket in the front, I can take my small daughter to school, to the library, to the shops, and to anywhere.
    I use it most in summer when the weather is warm and dry. It can be very unpleasant in winter when it is cold and the snow is heavy. Of course, you must be careful on a bicycle. Accidents are not the only problem. One day I went shopping with my friends. But when I came back, I found that my bike's front wheel was missing. It was a long walk to the bicycle shop. Now I have three strong locks(锁).
    My husband uses my bicycle sometimes for short journeys. He says it is better than waiting for a bus. He still uses his car for longer journeys, but I think that all the sitting down is making him fat and lazy. I like riding on my bicycle because I can exercise a lot and get much fresh air, and this makes me feel much younger.
____ Jane thinks a bicycle is __________ than a car if you live in a town.
____ It's convenient to use a bicycle because you can ride it to anywhere and needn't worry about __________.
____ When it is __________ in summer, Jane rides her bicycle.
____ For short journey, Jane’s husband doesn’t want to wait for a bus. He would like to __________.
____ Jane can get a lot of __________ and fresh air, so she likes riding very much.

    The Mandarin version of The Sound of Music will return to Beijing from Aug 18 to Sept 3,after its first tour of the country last year.Performed first in July 2016,the musical,produced by Seven Ages,a Beijing-based company devoting to adapting classical Western musicals into Chinese versions,has been staged more than 100 times and attracted over 100,000 people.

    The Broadway show,based on the book The Trapp Family Singers,which was written by Maria Von Trapp about her real-life experiences and published in 1949,made its debut in 1959.With music by Richard Rodgers and lyrics by Oscar Hammerstein II,it won five Tony Awards,including Best Musical.When the Oscar-winning film with the same title was screened in China in the 1970s,the movie,which was released by Twentieth Century Fox in 1964,was very popular,especially its songs,such as Do-Re-Mi and Edelweiss.The Broadway production and the production by composer Andrew Lloyd Webber both toured China in 2008 and 2014,which expanded its Chinese fan base.

    The upcoming tour will see actors,including 11-year-old Beijinger Qiu Jiahao and 5-year-old Liang Xiaoxian, play the seven children in the family.Fu Zhenhua,a graduate of the Shanghai Theater Academy,and Dang Wenwei,a graduate of the Shanghai Conservatory of Music,will play the roles of Captain Georg von Trapp and Maria Rainer.

    "My favorite aspect of this musical is the way it takes a look at various kinds of love we experience as human beings and even the love of things spiritual and unexplainable.And that is what I like most about The Sound of Music-it really is the sound of love," says Graves,a veteran Broadway director,who has lived and worked in China since 2002.

    After Beijing,the musical will be staged in Shenzhen in December and Shanghai next January.
