    Expensive perfumes (香水) come in tiny bottles, but many hide a whale-sized secret.

    To perfect a particular smell, perfume-makers often use an ingredient that comes from sperm whales, called ambergris (龙涎香). But using ambergris, which helps a perfume last longer, is strongly opposed by many people who think it is wrong to kill whales just so we can smell sweet. Joerg Bohlmann is neither a perfumer nor a whale expert. He's a plant biologist at the University of British Columbia in Canada. But his discovery of a new plant gene (基因) might push whales out of the perfume business.

    The gene comes from fir trees, found throughout North America and commonly used as Christmas trees. The trees produce a chemical that can be used in perfume in place of ambergris-but with a catch. "There's a problem that many people wouldn't consider. In the tree, the chemical is mixed with many others. That makes separation a challenge," Bohlmann says. "lt's like trying to isolate sugar from a biscuit. "

     This is where science becomes useful. When Bohlmann learned that fir trees produce the ambergris-like chemical, he decided to use his gene know-how to find the instructions for how to make the ambergris-substitute.

    Bohlmann found that gene and took it out of the tree cells. Then he did something that might sound strange to someone who doesn't work in genetics: Bohlmann put the gene from the tree into yeast (酵母) cells.

    Yeast may sound familiar because it's used to make things like bread, wine and beer. Biologists like to work with yeast because it easily adopts new genes and changes its features and behaviour. When Bohlmann put the fir tree gene into the yeast, the yeast started making the same chemical that had been produced by the tree.

    Perfumers pay big money for ambergris because it is a fixative, which means it holds a smell in place on a person's body.

    "Cheap perfumes smell good in the first hour or so and then everything is gone," explains Bohlmann. "But expensive perfumes are much more stable.  Their smell lasts much longer, for hours or even a day after you apply them. "

    The new chemical, made from the tree genes, can be used as a fixative, too. And using yeast to make it is far cheaper than acquiring ambergris.

    Bohlmann admits he never thought he'd get into the perfume business. But now, he says, producers have been calling to find out how to use his technology in new perfumes.

(1)、It can be inferred from the passage that if a perfume contains ambergris,           .

A、its user probably supports whale hunting B、it is probably very expensive C、its smell will last for about an hour D、there will be a whale symbol on the bottle
(2)、The underlined expression "with a catch" in Paragraph 3 means____.

A、being difficult to hold B、being too similar C、having a hidden problem D、needing further testing
(3)、According to the passage, why are yeast cells often used in genetic research?

A、They're much cheaper to use than ambergris. B、They can reproduce much faster than other cells. C、They share some of the qualities of plant genes. D、They can take on the characteristics of other genes.
(4)、What can we learn about Joerg Bohlmann from the passage?

A、He is opposed to whale hunting. B、He made his discovery during Christmas. C、He has worked in the perfume industry for many years. D、He has previously done genetic research.

    A popular saying goes, "Sticks and stones may break my bones, but words will never hurt me." However, that's not really true. Words have the power to build us up or knock us down. It doesn't matter if the words come from someone else' or ourselves—the positive and negative effects are just as lasting.

    We all talk to ourselves sometimes. We're usually too shy to admit it, though. In fact, more and more experts believe talking to ourselves out loud is a healthy habit.

    This "self-talk" helps us encourage ourselves, remember things, solve problems, and calm ourselves down. Be aware, though, that as much as 77% of self-talk tends to be negative. So in order to stay positive, we should only speak words of encouragement to ourselves. We should also be quick to give ourselves a pat on the back. The next time you finish a project, do well in a test, or finally clean your room, join me in saying "Good job!"!

    Often, words come out of our mouths without thinking about the effect they will have. But we should be aware that our words cause certain responses in others. For example, when returning an item to a store, we might use warm, friendly language during the exchange. And the clerk will probably respond in a similar manner Or harsh (刻薄的)and critical language will most likely cause the clerk to be defensive.

    Words have power because of their lasting effect. Many of us regret something we once said. And we remember unkind words said to us! Before speaking, we should always ask ourselves: Is it loving? Is it needed? If what we want to say doesn't pass this test, then it's better left unsaid.

    Words have power: both positive and negative. Those around us receive encouragement when we speak positively. We can offer hope, build self-esteem(自尊) and encourage others to do their best Negative words destroy all those things. Will we use our words to hurt or to heal? The choice is ours.

    Ownership used to be about as straightforward as writing a cheque. If you bought something, you owned it. If it broke, you fixed it. If you no longer wanted it, you sold it or threw it away. In the digital age, however, ownership has become more slippery. Since the coming of smartphones, consumers have been forced to accept that they do not control the software in their devices; they are only licensed to use it. As a digital chain is wrapped ever more tightly around more devices, such as cars and thermostats, who owns and who controls which objects is becoming a problem. Buyers should be aware that some of their most basic property rights are under threat.

    The trend is not always harmful. Manufacturers seeking to restrict what owners do with increasingly complex technology have good reasons to protect their copyright, ensure that their machines do not break down, support environmental standards and prevent hacking. Sometimes companies use their control over a product's software for the owners' benefit. When Hurricane Irma hit Florida this month, Tesla remotely updated the software controlling the batteries of some models to give owners more range to escape the storm.

    But the more digital strings are attached to goods, the more the balance of control leans towards producers and away from owners. That can be inconvenient. Picking a car is hard enough, but harder still if you have to dig up the instructions that tell you how use is limited and what data you must give. If the products are intentionally designed not to last long, it can also be expensive. Already, items from smartphones to washing machines have become extremely hard to fix, meaning that they are thrown away instead of being repaired.

    Privacy is also at risk. Users become terrified when iRobot, a robotic vacuum cleaner, not only cleans the floor but also creates a digital map of the inside of a home that can then be sold to advertisers (though the manufacturer says it has no intention of doing so). Cases like this should remind people how jealously they ought to protect their property rights and control who uses the data that is collected.

    Ownership is not about to go away, but its meaning is changing. This requires careful inspection. Devices, by and large, are sold on the basis that they enable people to do what they want. To the extent they are controlled by somebody else, that freedom is compromised.

    I'd like to share a little story with you about something that happened when I was four. I remember it clearly. Our loving family dog was nearing the end of his life. My father picked him up and put him in a little bed we had made for him. Our dog, my companion, whom we had cared for, bit my father when he attempted to help him. How could he? Why? I couldn't understand it. I didn't like him anymore.

    I hadn't thought about that story for a long time but something that happened last week brought it back to me. I went to speak with a friend. When I knocked on the door, I met in an instant an angry look and a few harsh(尖刻的)words. When the door was slammed(砰地关上)in my face, I stood there shocked, and in a rush, I was reminded of my dog bit my father 20 years ago or so. What brought that story back was that same feeling of betrayal.

    Both stories taught me something the next day. You see, when I got up in the morning and was told my dog had died, it became clear to me that he must have been in great pain. For him to have bitten a family member, he could not have been himself. Much the same for the other story when I learned that my friend's wife had just left him.

    We are all beings of our environments, our opinions and feelings. And all of those things can cause you to say and do things that can't be understood by those who are not in the same situation with you.

    If you meet someone either behaving out of character or acting in a way that doesn't seem to fit the situation, put out your hand and be patient when you think it is least possible for him to do so. You may turn around a story that has a sad ending simply by your actions.

    Most of us have looked up at the stars that fill the night sky and wondered whether we're alone in the universe. Indeed, the question of whether there's life out there has been something humankind's been asking itself for countless years. But thanks to China's Five-hundred-meter Aperture Spherical Telescope (FAST), the answer to this question may come a lot sooner than we expected.

    The telescope has a huge round reflector, which measures 500 meters across and has a perimeter(周长)of 1.6 kilometers. Because of its great size, it would have been both difficult and inefficient to get FAST to move like a regular telescope. Instead, FAST's designers came up with a great solution: its surface is made up of 4450 panels which can be individually adjusted. This clever design feature allows scientists to detect radio signals from any angle with a great degree of accuracy. "Panels can change their positions through connected wires and parallel (关联的) robots. We can control their position with an accuracy of 1mm," Zheng Yuanpeng, chief engineer of the telescope's panel project, told Xinhua News Agency.

    FAST's engineers also had the task of finding a suitable location. As any interference would affect its ability to detect distant radio waves, it needed to be built in a remote area. Luckily, the perfect spot was found in the beautiful mountains of Guizhou Province. "There are three hills about 500 meters away from one another, creating a valley that is perfect to support the telescope," Sun Caihong, chief engineer of FAST's construction, told Xinhua.

    And although it wasn't yet fully operated, FAST had already made great discoveries by October 2017. Since 1967, only around 2000 pulsars (脉冲星) have been discovered, yet FAST had detected six more by October 2017. Once FAST is fully up and running, we may finally have the answer to one of the biggest questions in history.
