2 . The Last Robot-Proof Job in America?

You can get most food, such as warm cookies or vodka, to your doorstep in minutes. But try getting a red snapper (红鲷鱼). Until recently, if you could obtain it, it would likely have been pre-frozen and shipped in from overseas.

A new tech startup is aiming to ____________this situation. Based inside the Fulton Fish Market, a seafood wholesale market, the startup, called FultonFishMarket.com, allows customers across the whole country, both restaurants and individuals, to buy from the market. The fish is shipped ____________, rather than frozen, thanks to an Amazon advanced logistics system. Mike Spindler, the company’s C.E.O., said recently, “I can get a fish to Warren Buffett, that’s as fresh as if he’d walked down to the pier (码头) and bought it that morning.”

There is one thing, ____________, that the sophisticated logistics system cannot do: pick out a fish. If Warren Buffett orders a red snapper, the company needs to ____________ that his fish is actually red snapper, and not some other. According to the ocean-conservation organization, more than 20% of the seafood in restaurants and grocery stores in America is ___________. For this task, the company has employed Robert DiGregorio, a forty-seven-year veteran of the business, who possesses a blend of judgement and ___________ knowledge that, so far, computers have yet to replicate.

“___________ the food-safety stuff, our business could be any market from the last three thousand years of human history,” Spindler told me. He is experienced in the ___________ business. When he arrived at the fish market in 2014, people were cautious. “They thought selling fish on the Internet was___________.” DiGregorio said, speaking for the fishmongers(鱼贩). “They didn’t see how it could possibly work.” Five years ago, DeGregorio didn’t know how to use a computer, but when the Web-site people arrived at the market, he sensed an opportunity. Together, they’ve created a human-machine fish-buying operation.

By 1 a.m. each night, the company collects __________ from around the country and sends them to DiGregorio. He heads into the market, carrying his tablet computer. The company’s algorithms（算法） ___________ data on their sources and can tell DiGregorio, for example, which stall to go to get the best tuna (金枪鱼). The computer is a “learning system,”, so if DiGregorio makes a choice it didn’t ___________, it asks, “Was the fish not available? Was it damaged?” All that information is fed back in for next time.

Then, what can a fishmonger see that a computer can’t? DeGregorio showed me his part of the ___________ process. “I’m assessing a few things,” he said. First, ___________. Fish should have “nice” slime(粘液). Then, smell. He sniffed the air above the box. “when fish goes bad, it smells like ammonia.” Besides, to get the best stuff, “Fishmongers have to have a relationship with you. To trust you.” He added.

Is he ever __________being replaced by the learning system of computers? DiGregorio shrugged. “By the time they invent a computer that can do what I can do,” he said, “I’ll be dead.”

3 . Babies made from three people approved in UK

Babies made from two women and one man have been approved by the UK’s fertility regulator. The historic and controversial move is to prevent children from being born with deadly genetic diseases.

Doctors in Newcastle — who developed the advanced form of In Vitro Fertilization or IVF (人工授精) — are expected to be the first to offer the procedure and have already appealed for donor eggs. The first such child could be born, at the earliest, by the end of 2017.

Some families have lost multiple children to incurable mitochondrial (线粒体的) diseases, which can leave people with insufficient energy to keep their heart beating.

The diseases are passed down from only the mother, so a technique using a donor egg as well as the mother’s egg and father’s sperm has been developed.

The resulting child has a tiny amount of their DNA from the donor, but the procedure is legal and reviews say it is ethical (伦理的) and scientifically ready.

“It is a decision of historic importance,” said Sally Cheshire, chairwoman of the Human Fertilisation and Embryology Authority (HFEA). “I’m sure patients will be really pleased by what we’ve decided today.”

But some scientists have questioned the ethics of the technique, saying it could open the door to genetically-modified(转基因) ‘designer’ babies.

The HFEA must approve every clinic and every patient before the procedure can take place. Three-person babies have been allowed only in cases where the risk of a child developing mitochondrial disease is very high.

Prof Mary Herbert, from the Newcastle Fertility Centre, said, “It is enormously pleasing that our many years of research in this area can finally be applied to help families affected by these devastating diseases”.

“Now that we are moving forward towards clinical treatments, we will also need donors to donate eggs for use in treatment to prevent affected women transmitting disease to their children.”

Prof Sir Doug Turnbull, the director of the Welcome Centre for Mitochondrial Research at Newcastle University, said, “We are delighted by today’s decision. We will also provide long-term follow up of any children born.”

NHS England has agreed to fund the treatment costs of the first trial of three-person IVF for those women who meet the HFEA criteria, as long as they agree to long-term follow up of their children after they are born.

1. Why is it historically important to approve babies made from three people?

A．It helps couples who lose the ability to give birth to a baby.

B．It marks a foundation stone to change babies’ appearances before birth.

C．It stops deadly genetic diseases passing down to newly-born babies.

2. Which of the following is TRUE about mitochondrial diseases?

A．They pass down on to babies from their parents.

B．They prevent people’s heart from functioning normally.

C．Some children infected can be cured with proper treatment.

D．Babies can be infected with them through a donor’s egg.

3. How can a clinic or a patient be approved of applying the three-person baby technique?

A．Only when the baby to be born needs it to survive.

B．Only when the patient gets financially prepared.

C．Only when the clinic gets scientifically ready.

D．Only when the technique is ethnically accepted.
