【推荐1】It was my first time visiting the United States. Before    1    (leave) for Washington D.C., I downloaded some introductions about some tourist    2    (attract) in the city. Therefore I knew something about this city before the trip. A lot of things happened during my trip to Washington D.C. However,     3    impressed me most is the International Spy Museum, which I visited on the     4    (three) day of the trip.

In my spare time, I often watched movies about spies with my parents because I was    5     (extreme) interested in spies. I acquired    6    good knowledge of that after I read the descriptions in the museum. I learned that spies usually hid important letters in an umbrella, in a shoe, or even in a pair of ordinary    7    (glass). When they thought they were probably found out, they could have their appearances    8    (change) in a few minutes. They put on fake hair, eyes or teeth. If they had an emergency, they even changed a smaller pair of shoes to change their walking styles in order not to    9    (recognize).

    10    conclusion, it was a nice trip. I had a good time in Washington D.C.. I will remember this trip forever.

Did you watch the popular TV series Meet Yourself during your winter vacation? In the TV series, the heroine Xu Hongdou travels to a village in Yunnan province and volunteers at a local café. She gets free meals     1     return.

As the show finds a growing audience, volunteer travel (an old-yet-modern form of travel) similar to Xu’s type of work has attracted more attention.

During the trip, volunteer travelers often provide     2     (service) like teaching, cooking, animal     3    (care), and cultural activities. In exchange for     4     (they) help, the volunteers may get free or    5    (discount) accommodation, meals and laundry, activities or classes.

    6     (tradition), the volunteer activities take place in a foreign country. However, just as what Meet Yourself depicts, more volunteer trips     7     (take) place within     8     same countries or regions the volunteers originate from in recent years. People try volunteer travel for several reasons. By     9     (work) voluntarily while traveling, travelers may make a real, positive impact on the world.

For those     10     are sick of urban pressure but can’t make up their minds whether to move permanently to the countryside, volunteer travel can be a solution.

In this way, travelers can catch some relief from their busy lives.
