【题目】Betty and I are best friends. Our birthdays are on the same day, so every year we have a birthday party together. But this year, we had a costume party（化装晚会） instead.

While we were writing the invitations, my mum came in and asked, “Why not invite John?” John had been in our class for only a few months, but he was already getting better grades in math than anyone else in class. I wrinkled(皱起) my nose, “Mum, he wears the same pants to school every day. How could he even afford a costume?” Mum said nothing. The next day, mum gave me an envelope with a shopping certificate(凭证) in it.” I thought it would be nice for you to give this to John.” Mum said. But how? We didn't want to make John embarrassed. We discussed it for a long time. Finally, Betty and I had a good idea.

【题目】 A Bite of China is a program with the rich culture and history about Chinese food. Besides introducing many kinds of delicious food across the country, it also shows Chinese society by explaining how these dishes came out and they are made, the relationship between people and food and a little Chinese philosophy(哲学). The first and second seasons were great successes. However, the third season was seen by viewers as a huge disappointment.

Criticizing(批评) the latest eightsection program has already become hot online. Criticism has mainly focused on two points: inaccurate or controversial(有争议的) content and the method of storytelling.

The program mixes up “Malatang” and “Chuanchuanxiang”， two different types of local spicy dishes in Sichuan Province. What's more controversial is that in one section “medicine and food come from the same origin(起源)，” which advises people to put traditional Chinese medicine into dishes without mentioning the risks.

As for the storytelling of the program, the new season has focused more on people's life stories than food. Criticism reached the top after one section, in which not traditional “Shuaimian (hitting noodles)” but the personal story of a chef who struggles to make a living in the big city was introduced in detail. It's surprising that a food program would ignore the food itself.

A change in the program team may be one of the reasons. The team said, “When the first season was put on, there were only about 40 food programs in China. But now the number is around 500. People's expectations are changing.” There are reasons for this opinion, but it's believed that “the devil is in the details”．

【1】A Bite of China is a program including rich ________ about Chinese food.

A.politicsB.geographyC.historyD.art

【2】What shows the third season is inaccurate?

A.Chinese food contains some philosophy.B.“Malatang” equals to “Chuanchuanxiang”．

C.Medicine and food are from the same origin.D.“Shuaimian” can be called hitting noodles.

【3】The underlined word “content ” in the passage means “________” in Chinese.

A.评论B.事物C.内容D.理论

【4】What's the reason for the failure of the third season?

A.Too many similar programs.B.Audience's high expectations.

C.The first two seasons' success.D.Lack of the eagerness for perfection.

【5】What is the main idea of this passage?

A.To introduce a popular TV program.

B.To let people know Chinese traditional culture.

C.To show people's love of this TV program.

D.To describe some opinions on the TV program A Bite of China.
