Recently there has been a discussion on a website about “what would you miss most and least if you were stuck on a desert island?”

Here are some of the answers:

Post 1

Steve USA—Hi, everyone. What would you miss most and least if you were stuck on a desert island? For me, it would be the changing seasons in New England. I guess this will sound stupid but I'd probably miss the rain, too. I wouldn't miss getting up at six every day to go to work, though! What about you?

Post 2

Tomas Germany—Good question. Steve, I think I'd miss different types of bread, and shopping at the supermarket. I'd miss the food most. What would I miss least? My mobile phone—I'd like to be completely quiet—at least for a little while.

Post 3

Paola Italy—I would miss the company of people because I know I'd like to have someone to share experiences with. I'd go mad on my own. And I sure wouldn't miss junk mail—I hate coming home every evening and a pile of junk mail in my post box.

Post 4

Miko Japan—Hi, I would miss Manga cartoon, the Internet and Japanese food, like sushi. I'd also miss TV shows and shopping for clothes… In fact, I'd miss everything.

Post 5

Roger UK—I would miss my daily newspaper and listening to the news on TV and radio. I'd feel very cut off if I didn't know what was happening in the world. What I'd miss least would be traffic jams in the city, particularly my journey to work.

Post 6

Jayne Russia—Why hasn't anyone mentioned their family? I'd be lost without my husband and two kids. They're the most important for me. And I can't get started in the morning without a cup of black coffee. I wouldn't miss doing the housework!

Even as Google plans to test its fleet（車隊(duì)）of self-driving cars on public roads this summer, its business model remains a bit of a mystery. By 2025, as many as 250,000 self-driving vehicles could be sold each year globally, according to a study by an industry research firm.

"Vehicles that can take anyone from A to B at the push of a button could transform mobility for millions of people," said Chris Urmson, director of Google's self-driving car project. For now, Google has no plans to sell any of its self-driving cars. They are strictly for research. But they will hit public roads this summer near Google's headquarters in Mountain View, California. Previous testing has taken place only on closed courses.

The cars are built to operate without a steering wheel, accelerator（油門）or brake pedal. "Our software and sensors do all the work," Urmson said. "The vehicles will be very basic—we want to learn from them and adapt them as quickly as possible—but they will take you where you want to go at the push of a button." The prototype（雛形）are the first of a 100-car fleet the tech giant is building.

In the long run, Urmson sees a future of safer roads—the majority of auto accidents are caused by human error—and fewer traffic jams. Robotic cars could also shuttle people who can't drive because of age or illness.

Google has said that self-driving cars could launch new business models in which people buy the use of vehicles they don't own. The company has already tested other types of self-driving cars on public streets, including modified Lexus sport-utility vehicles, under a special permit program by the California Department of Motor Vehicles that requires a human driver at the controls.

The state has issued six other companies permits to operate such cars, including Delphi, Mercedes-Benz, Volkswagen, Tesla, Bosch and Nissan. The vehicles that will be tested on open roads this summer will have removable steering wheels, accelerators and brake pedals to allow "safety drivers" to take control if needed.

Google says the cars are safe. The vehicles have sensors that "can detect objects out to a distance of more than two football fields in all directions, which is especially helpful on busy streets with lots of intersections," Urmson said. "We're looking forward to learning how the community understands and interacts with the vehicles, and to uncovering challenges that are unique to a fully self-driving vehicle," Urmson said.

1.The passage informs us that self-driving cars __________.

A. will probably decrease traffic jams

B. have already passed necessary tests

C. have been purchased by some companies

D. will be able to communicate with drivers

2.According to Chris Urmson, ______________.

A. software and sensors are vital for self-driving cars

B. self-driving cars can give driving orders to humans

C. self-driving cars are specially designed for the elderly

D. ordinary vehicles will be replaced by self-driving cars

3.The underlined word "intersections" in the last paragraph probably means ______________.

A. accidents B. buildings

C. crossings D. vehicles

4.What is the best title for this passage?

A. Self-driving Car Avoids Human Errors

B. Self-driving Car Meets New Challenges

C. Google's Self-driving Car Enjoys Global Popularity

D. Google's Self-driving Car Graduates to City Streets

More than four decades ago British scientist Robert Edwards first witnessed the miracle of human life growing inside a test tube at his Cambridge lab. Since that ground-breaking moment, more than four million babies have been born through IVF and in 2010 his great contribution to science was finally recognized as he was awarded the Nobel Prize for medicine.

The prize for Dr. Edwards, who was given a Daily Mirror Pride of Britain Award in 2008, includes a £900,000 check. The Nobel Assembly described IVF as a “milestone in modern medicine”.

With the help of fellow scientist Patrick Steptoe, the Manchester-born physiologist developed IVF - leading to the birth of the world’s first test tube baby. Dr. Steptoe died 10 years later but their work has transformed fertility treatment and given hope to millions of couples.

It was a scientific breakthrough that transformed the lives of millions of couples. They said: “His achievements have made it possible to treat infertility, a disease which makes human unable to have a baby. This disease has been afflicting a large percentage of mankind including more than 10% of all couples worldwide.”

Louise Brown, the world’s first test tube baby, made international headlines when she was born in Oldham, Manchester, in 1978 to parents Lesley and John who had been fruitlessly trying for a baby since 1969.

IVF-----in-vitro fertilization is the process whereby egg cells are fertilized outside the body before being implanted in the womb. After a cycle of IVF, the probability of a couple with infertility problems having a baby is one in five—the same as healthy couples who conceive naturally.

Professor Edwards, who has five daughters and 11 grandchildren, began his research at Cambridge University in 1963, after receiving his PhD in 1955. He once said: “The most important thing in life is having a child. Nothing is more special than a child.” With the help of fellow scientist Patrick Steptoe, Prof. Edwards founded the Bourn Hall clinic in Cambridge shire, which now treats more than 900 women a year. Each year, more than 30,000 women in Britain now undergo IVF and 11,000 babies are born as a result of the treatment.

But his work attracted widespread criticism from some scientists and the Catholic Church who said it was “unethical and immoral”.

Martin Johnson, professor of reproductive sciences at the University of Cambridge, said the award was “l(fā)ong overdue”. He said: “We couldn’t understand why the Nobel has come so late but he is delighted - this is the cherry on the cake for him.”

Professor Edwards was too ill to give interviews but a statement released by his family said he was “thrilled and delighted”.

1.What is Robert Edwards’ contribution to science?

A. Enabling millions of couples to live a better life.

B. Seeing the wonder of the first tube baby growing

C. Helping couples with infertility to have tube babies.

D. Challenging a disease which stops human having a baby.

2.What does the underlined word “afflicting”(Paragraph 4)most probably refer to?

A. Troubling B. Developing

C. Improving D. Confusing

3.Why did Professor Edwards begin his research on tube baby?

A. Because he thought it of great significance to have a child in life.

B. Because the birthrate around the world was unexpectedly low then.

C. Because a special child did make a difference to an ordinary family.

D. Because his fellow scientist wanted to give hope to the unlucky couples.

4.It can be inferred from Paragraph 8 and Paragraph 9 that ___________.

A. Professor Edwards deserved the prize for his breakthrough.

B. different opinions were voiced on Professor Edwards’ achievement.

C. some people envied Professor Edwards for his being awarded.

D. the prize was late because the finding was first considered immoral.

5.What might be the best title for the passage?

A. Life Stories of Robert Edwards

B. Preparations for Having a Baby

C. Nobel Prize for IVF Expert Edwards

D. Treatment of Infertility in a Lab

Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, texting or checking updates on WeChat without looking at what was going on around them. As the number of this new “species” of human has kept rising, they have been given a new name — phubbers（低頭族）.

Recently, a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities(身份) bury themselves in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes selfie in front of a car accident site, and a father loses his child without knowing about it while using his mobile phone. A chain of similar events eventually leads to the destruction of the world.

Although the ending sounds overstated, the damage phubbing can bring is real.

Your health is the first to bear the effect and result of it. “Constantly bending your head to check your cell phone could damage your neck,” Guangming Daily quoted doctors as saying. “the neck is like a rope that breaks after long-term stretching.” Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report.

But that’s not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.

It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight.

1.For what purpose does the author give the example of a cartoon in Paragragh2?

A. To inform people of the bad effects of phubbing.

B. To advertise the cartoon made by students.

C. To indicate the world will finally be destroyed by phubbers.

D. To warn doctors against using cell phones while treating patients.

2.Which of the following is NOT a risk a phubber may have?

A. His social skills could be affected.

B. His neck and eyesight will be gradually harmed.

C. He will cause the destruction of the world.

D. He might get separated from his friends and family.

3.Which of the following may be the author’s attitude towards phubbing?

A. Supportive. B. Opposed

C. Optimistic. D. Objective.

4.What may the passage talk about next?

A. Advice on how to use a cell phone.

B. People addicted to phubbing.

C. Measures to reduce the risks of phubbing.

D. Consequences of phubbing.
