1 . “I seldom read posts on WeChat Moments because many of them are not true and don’t present what a person is really like,” a friend of mine told me. Then, I ______ a small gathering at a bar a few days ago, and a girl asked me why my posts are full of positive energy—as if there is nothing ______ in my life.

I reread my WeChat posts to ______ whether what she said was true, and surprisingly, it seems my daily life ______ smoothly with almost all my posts filled with high spirits. As we know, online and offline communication are the two ______ for interpersonal exchange. WeChat is among the popular online social platforms in China, and people share their ideas and ______ personal images by posting on WeChat Moments. One way to build a better personal image is to polish photos, ______ selfies or other portraits by using photo editing apps ______ posting them on WeChat.   It helps ______ a sense of goodness and happiness to other users. Another way to ______ our charming personality is by posting ideas or comments. We take account of a lot of things before we post on WeChat.

However, sometimes it is the posts that take a negative tone or those that we delete that carry our ______ self-expressions. I once had a stomachache and went to hospital by myself to ______ a physical examination. Then, I had to do all the tests to ______ the cause of my illness on my own. In the outpatient area, all the patients except me were ______ by family or friends. Loneliness suddenly overcame me and ______ me to post on WeChat Moments. I described how I felt and expressed my ______ to look for someone to take care of me. Many friends left messages to ______ me and wish me a speedy recovery. But some suggested that I become stronger to deal with such situations. The reactions to my self-expressions vary. So, why do I ask for ______ by posting the other side of me on WeChat Moments?

WeChat posts are ______ with reliability and untruthfulness. We post our thoughts with invisible masks to hide whatever we refuse to tell the world. But ______, WeChat still provides an effective way for us to learn more about someone.

2 . The first time I ordered takeout in New York, two things surprised me: the last speed with which the food _________ and the fact that, after I’d paid for it, the man from the Chinese restaurant and I stood on either side of the threshold（门槛） _________ each other, though only one of us understood_________. After a minute of this, I closed the door. An American friend sat on the sofa, open-mouthed “Wait—did you just close the door?”

In London, you don’t tip for _________. A man on a motorbike arrives and hands over an oil-soaked bag, or a box. You give him the _________ amount of money it costs or wait and look at your shoes while he _________ change. Then you close the door. Sometimes all this is _________ without even the removal of his motorcycle helmet. The dream is that the whole _________ exchange passes wordlessly.

Every New Yorker has heard a newly arrived British person complain about _________. The high-minded British people add a(n)____________: food-industry workers should be paid a(n)____________ wage (although the idea that the delivery boys of Britain are well paid is generally an untested ____________).

Now when I’m in London I find myself tipping all kinds of people, most of whom express a sort of genuine ____________, even if the tip is tiny. What they never, ever do,____________ is tell me to have a nice day. “Have a good one”—said slowly with a slightly sad air, as if avoiding the far greater ____________ of an evil “one”—is the most you tend to hear.

But I’m not going to complain about Britain’s ____________ of a service culture. I don’t think any nation should ____________ service to the status of culture. At best, it’s performed politely and properly by both parties, but no one should be asked to ____________ that the intimate（亲密的）satisfaction of her existence is serving you, the “guest”, with a shrimp sandwich wrapped in plastic. We are heavily affected by enough false beliefs in this life without ____________ them the one that the girl with the name tag is ____________ in love with us.
