        Twelve years ago, Danny called me from a dark, damp subway station. “A baby!” he shouted. “Get down here, and flag down a police car or something.” By nature, Danny is a remarkably calm person, so when I felt his heart pounding through the phone line, I ran.

        When I got to the subway station, Danny was holding a light-brown-skinned baby, about a day old. The baby had been wrapped in an oversize black sweatshirt and left on the ground in a corner behind the gate.

        Three months later, Danny appeared in family court to give an account of finding the baby. Suddenly, the judge asked, “Would you be interested in adopting this baby?” The question stunned everyone in the courtroom, except Danny, who answered, simply, “Yes.”

        “But I know it's not that easy,” he said.

        “Well, it can be,” assured the judge before barking out orders to allow me to be a parent-to-be.

        My first reaction, when I heard, went something like: “Are you crazy? How could you say yes without consulting me?”

        In three years as a couple, we had never discussed adopting a child. I was an ambitious playwright working as a part-time word processor. Danny was a respected yet wildly underpaid social worker. We had a roommate, who slept in our living room, to help pay the rent.

        We knew how many challenges couples usually faced when they wanted to adopt. And while Danny had patience and selflessness, I didn't know how to change a diaper(尿布), let alone nurse a child. I didn't trust the system and was sure there would be obstacles. Also, I couldn't handle parenthood. So I promised myself I wouldn't get attached.

        The caretaker held him and then placed him in my arms. But when the baby stared up at me, with all the innocence and hope he represented, I, like Danny, was completely hooked.

    (1)Why did the author rush to the subway station?
    A . Because Danny finally found their long lost son. B . Because she sensed Danny met something urgent. C . Because Danny was knocked down by a police car. D . Because Danny wasn't a remarkably calm person by nature.
    【答案】
    (2)How did the author react on hearing Danny's answer to the judge's question?

        On a February day during an unusually mild winter, found myself missing the snowy beauty. I enjoyed the feeling that comes from watching snow fall gently from heaven while I'm cosy inside with a good fire burning in the stove. But there were more serious concerns, like the lack of rainfall making our woods more accessible to summer forest fires. Local ski fields and hotels, all dependent on a snowy season, felt sorry for the vacant lifts, empty restaurants and unused snowmobiles.

        Then I happened to see three little robins (知更鸟) fly into our yard. What were they doing here? West of us, in the Willamette Valley, wild flowers burst this time of year. But here in central Oregon, even if a groundhog (土拨鼠) had wanted to appear, it couldn't have broken through the frozen earth. And yet, these robins had arrived.

        Their presence brought me a flow of happiness. It felt like a celebration as I dug into my bag of birdseed and spread a handful on the ground. Above me, the deep blue sky was cloudless, perfectly quiet but for some smoke from a neighbor's chimney. The lively cold made the air fresh and clean.

        My robins jumped lightly toward the seed. My soul jumped with them, feeling equally carefree. Caught up in the moment of spring fever, I checked our snowless flower beds. To my delight, I spotted a green branch sticking out through the brown soil.

        Despite the cold, I wasn't ready to go back inside. Just a short meeting with those robins had renewed my spirit. The next day I would return to my outdoor work with a cheerful heart and a hopeful eye for these signs of spring.

        Imagine you're standing in line to buy a snack at a store. You step up to the counter and the cashier scans your food. Next, you have to pay. But instead of scanning a QR Code(二维码) with your smart phone, you just hold out your hand so the cashier can scan your fingerprint. Or, a camera scans your face, your eyes or even your ear.

        Now, this type of technology might not be far away. As technology companies move away from the traditional password, biometric (生物特征识别的) security, which includes fingerprint, face and voice ID, is becoming increasingly popular.

        In 2013, Apple introduced the iPhone 5s, one of the first smart phones with a fingerprint scanner. Since then, using one's fingerprint to unlock a phone and make mobile payments has become a commonplace, bringing convenience to our lives. And since 2016, Samsung has featured eye-scanning technology in its top smart phones, while Apple's new iphone X can even scan a user's face. But despite its popularity, experts warn that biometrics might not be as secure as we imagine." Biometrics is ideally good in practice, not so much," said John Michener, a biometrics expert.

        When introducing the new iPhone's face ID feature, Phil Schiller, Apple's senior vice-president, said. "The chance that a random person in the population could look at your iPhones X and unlock it with their face is about one in a million." But it's already been done. In a video posted on a community website Reddit, two brothers showed how they were each able to unlock the same iPhone X using their own face. And they aren't even twins.

        "We may expect too much from biometrics," Anil Jain, a computer science professor at Michigan State University, told CBS News. "No security systems are perfect."

        Earlier last year, Jain found a way to trick biometric security. Using a printed copy of a thumbprint, she was able to unlock a dead person's smart phone for the police, according to a tech website Splinter. "It's good to see biometrics being used more," Jain told CBS News, "because it adds another factor for security. But using multiple security measures is the best defense."

        Hacking isn't just for computers and smartphones, According to a study published last week in the journal Science, scientists have found a way to hack a plant's genes in order to make it use sunlight more quickly. Someday, the results could increase the amount of food produced around the world.

        Photosynthesis(光合作用)is the word used to describe how plants use sunlight, water, and carbon dioxide to make their own food. Scientists who conducted the new study say this is a very slow process. Plants use less than 1 percent of the energy available to therm. But by hacking a plant's genes, the scientists were able to increase the amount of leaf growth on plants between 14 and 20 percent.

        "Specifically, scientists hacked the plant's protective system. Normally, this system is activated when a plant gets too much sunlight, "said scientist Krishna Niyogi, co-author of the study. When the plant senses the light, it gets rid of extra energy and creates more leaves. When the plant is in shade, the protective system is turned off, but the process is slow.

        Stephen Long is the lead author of the study. He compared a plant's protective system to light-adjusting glasses. When a person wears the glasses outside during the day, the lenses(镜片)darken and lighten depending on how sunny it is. Plants do the same thing, he said. But in plants the adjustment can take anywhere from 10 minutes to an hour. This makes it hard for plants to get the right amount of sunlight needed to create food.

        The new study sped up the process. By changing the plant's genes, the protective system turned on and off more quickly than normal. As a result, leaf growth on the plants scientists used in the study increased. Leaf growth in two plants increased by 20 percent, while leaf growth on a third plant increased by 14 percent. Scientists conducted the study on tobacco plants. But they think the genetic changes will produce the same results in corn and rice.

        American and British people both speak English of course. But sometimes it does not seem like the same language. In fact, there are some important differences between British English and American English.

        First of all, they sound very different. Often, Americans don't say each word separately. They say several words together. Americans may say "I dunno" instead of "I don't know". Or they may say "Whaddaya say?" instead of "What do you say?" However, the British are more careful in their speech. They usually say all the words and keep them separate.

        Sound is not the only difference between British English and American English. Words sometimes have different meanings too. Some American words are never used in England. The same thing is true of some British words in America. For example, the vocabulary for cars and driving is very different. Americans drive trucks, but in England people drive lorries.

        Many expressions are also different in the two countries. In England,if you are going to telephone your friends, you "phone them up". In America, you "give them a call". When you are saying goodbye in England you might say "Cheerio!" In America you might say "See you later."

        There're also some differences in grammar. For example, Americans usually use the helping verb "do" when they ask a question. They say "Do you have a storybook?" But the British often leave out the helping verb. They say "Have you a storybook?"

        All these differences can be confusing if you are learning English. But most languages are like this. Languages change over time. When people live in separate places, the languages change in different ways. This is what has happened to English. It can also happen to other languages, such as French. Many people in Canada speak French, but their French is very different from the French of France.

    Biofuels (生物燃料), gained from plants and animal matter, are a key solution to the environmental problems caused by fuels like coal. "Bioalcohol (生物酒精) is the most common biofuel and is produced by sugars found in materials such as corn. With some engine redesigned, it can be used directly by cars, buses, etc. ," says Professor Daniel Tan, "12 percent of transport fuel could come from biofuels, especially bioalcohol, by 2030. "

    But a 2016 study of biofuels said, "Bioalcohol presently is mostly produced with food crops. Altogether, the environmentally-friendly biofuels rely on about 2-3 percent of the global water and land used for agriculture, which could feed a large number of hungry people. "

    Energy experts have therefore been trying to deal with the problem. Recent research led by an international team found that the agave (龙舌兰) plant might offer a way out. This plant tends to be the right bioalcohol source to supersede others such as sugarcane (甘蔗) and corn.

    Daniel Tan explains that the agave can be grown in unfavorable conditions and is not a major food crop. "It can grow in areas that lack water and rainfall without being watered by farmers, and it does not compete with food crops or put demands on limited water. This kind of useful plant is recently being grown in Australia. It can survive Australia's hot summers," he says.

    The study finds that sugarcane produces just a little more fuel per square meter each year than the agave. However, the agave outperforms sugarcane in a range of areas, including pollution to the earth, and water using. The agave uses 69 percent less water than sugarcane and 46 percent less water than corn for the same amount of fuel produced. As for corn,it produces less fuel per square meter each year than the agave.

    However, Daniel Tan states: "The first generation of bioalcohol from the agave recently faces a big competition from oil, whose recent low price makes it far more attractive to customers. Without some policy support from the government, bioalcohol production from the agave faces big challenges. "
