1．Easy to make and cheap to buy，instant noodles have long been China's ultimate convenience food.
   Since it was a snack for students，a meal on the train，or just the go-to choice for hungry workers，more than 46.2 billion packets were sold in China in 2013.But it seems this industry has gone off the boil.By 2016 those sales had declined to 38.5 billion，according to the World Instant Noodle Association，a drop of almost 17%.
   "This phenomenon shows an unnoticeable while continuous change in China's consumption（消費）patterns，" said Zhao Ping of the Academy of China Council for the Promotion of International Trade.He told the China Daily，"Consumers are more interested in life quality than just filing their bellies these days."
   About 730 million people in China now have access to the Internet according to government figures.And about 95% of those are using smart phones to connect.And apps that offer food delivery to your home，office or wherever you happen to be are a real fast developing industry.
   Their menus are undoubtedly more expensive than a pot of instant noodles.But these meals can still be inexpensive，and arguably more tasty，depending on your favour.
   But put in the global background，China is still easily the biggest market for instant noodles.In fact，China's consumption was roughly equal to Indonesia，Japan，Vietnam，India，the US，South Korea and the Philippines combined.
   And that means global noodle manufacturers are unlikely to turn away from the Chinese market.Japan's instant noodle business Nissin Foods，for example，is planning to land on the stock market，in Hong Kong，by which operation it hopes to raise about 145 million dollars.It is rare for a Japanese firm to list in Hong Kong，but Nissin is talking up its prospects in China，where it is already the fifth biggest brand.
   "Some consumers stopped consuming instant noodles，but most consumers want to increase the quality（of food they consume），" chief executive Kiyotaka Ando told CNBC last week，"We can supply high-quality products so we have more possibility to develop our business."

（1）The phrase "go off the boil" in Paragraph 2 is close in meaning to

.
A．stop boiling
B．turn down
C．develop rapidly
D．get out of control
（2）According to the text，it is because of

that people have more food choices.
A．the development of food manufacturing industry
B．the fall of price in foods beyond instant noodles
C．the technological development on communication
D．the people's doubt on instant noodles' food safety
（3）Which of the following descriptions is TRUE according to the text？

A．China consumes more instant noodle than any other country does.
B．China is beginning to lose its first place in instant noodle business.
C．Nissin is the fifth biggest brand of Japan's instant noodle business.
D．Nissin is planning to build an instant noodle factory in Hong Kong.
（4）We can infer from the text that

.
A．China's instant noodle consumption will continue to drop
B．Chinese people will favour cheaper instant noodles to save money
C．instant noodles will have a pessimistic prospect in the future
D．instant noodle manufacturers will focus more on its food quality

2．Professor Ashok Goel of Georgia Tech developed an artificially intelligent teaching assistant to help handle the enormous number of student questions in the online class，Knowledge-Based Artificial Intelligence.This online course is a core requirement of Georgia Tech's online Master of Science in Computer Science program.Professor Goel already had eight teaching assistants，but that wasn't enough to deal with the overwhelming number of daily questions from students.
Goel and his team developed several versions of a virtual assistant named Jill Watson before releasing her to the online forums.At first，the virtual assistant wasn't too great.Then they began to feed Jill with the questions and answers.After some adjustments and sufficient time，Jill was able to answer the students' questions correctly 97% of the time.The virtual assistant became so advanced and realistic that the students didn't know she was a computer.The students，who were studying artificial intelligence，were interacting with the virtual assistant and couldn't tell it apart from a real human being.Goel didn't inform them about Jill's true identity until April 26.The students were actually very positive about the experience.
The goal of Professor Goel's virtual assistant next year is to take over answering 40% of all the questions posed by students on the online forum.The name Jill Watson will，of course，change to something else next semester.Professor Goel has a much rosier outlook on the future of artificial intelligence than，say，Elon Musk，Stephen Hawking，Bill Gates or Steve Wozniak.

3．A record of 6.15 million trips was made by Chinese mainland tourists to overseas destinations during the seven-day Spring Festival holiday，which ended on Sunday，according to the China National Tourism Administration （CNTA）.That is an increase of 7 percent compared with the last year's Spring Festival.About 374，000 trips were organized by travel agencies，a 2.5 percent increase.
   The CNTA also reported growth from individual and high-end（高端的） travelers and said that in addition to top and coastal cities，inland cities such as those in Guangxi— became important source markets.With many Chinese now traveling abroad during the Spring Festival，their choice of destinations has expanded along with their growing interest in foreign cultures and services.
   "Chinese tourists are increasingly willing to experience local cultures and services，including staying in private homes，appreciating plants and watching monkeys，" Li Xuejing，an agency's marketing manager，said.
   Miss Guo，a Chinese tourist，who was vacationing on an island in Philippines，said， "I now pay more attention to relaxation and enjoyment during the holidays instead of shopping or choosing gifts for relatives."
