1 . The world’s coral reefs do more for the planet than provide underwater beauty. They protect shorelines from the effects of hurricanes. An estimated 500 million people earn their livelihood from the fishing stocks and tourism opportunities reefs provide. The tiny animals that give rise to reefs are even offering hope for new drugs to treat cancer and other diseases.
Despite their importance, warming waters, pollution, ocean acidification, overfishing, and physical destruction are killing coral reefs around the world. So now scientists around the world are looking for all kinds of ways to protect and maybe even revive(复苏) corals. In the Bahamas, Ross Cunning, a research biologist at Chicago’s Shedd Aquarium, is focusing on corals with genes that could make them natural candidates for restoration projects. He recently published a study of two Bahamian reefs, one that seemed to survive an intense 2015 heat wave, and one that didn’t.“It sets the stage to find out which genes are responsible for thermal tolerance,” says Cunning, adding that he hopes discovering those genes will help scientists one day breed more heat-tolerant coral.
In Massachusetts, Cohen’s research has found two key elements that seem to protect corals. The first: internal(内部的) waves beneath the ocean’s surface that bring cooler currents to heat-struck corals, essentially air-conditioning them as temperatures rise. The second: adaptation, a quality that corals found in Palau’s warm lagoons(环礁湖) seem to display.On average, these lagoons submerge(淹没) coral in water that is two degrees Celsius warmer than the water outside the lagoons. “We think the fact that they can deal with these higher temperatures is built into their genetics and allows them to deal with the heat waves.”
She’s also found evidence of corals evolving more quickly in the past two decades to withstand rapidly warming temperatures. The big question scientists are now enquiring into, says Cohen, is whether there’s a cap on how much more heat corals can adapt to. Cohen calls these regions with heat-adapted corals as “super reefs,” and like Friendlander, advocates for using marine reserves to protect them.

2 . Even if we’ve never laid eyes on a certain person, the sound of their voice can relay a lot of information: whether they are male or female, old or young, or perhaps an accent indicating which nation they might come from. While it is possible for us to randomly deduce someone’s facial features, it’s likely that we won’t be able to clearly piece together what someone’s face looks like based on the sound of their voice alone. However, it’s a different matter when machines are put to the task, as researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have discovered in developing an AI that can vividly reconstruct people’s faces with relatively impressive detail, using only short audio clips(音频片段) of their voices as reference.
Named Speech2Face, the neural(神经的) network — a computer that “thinks” in a manner similar to the human brain — was trained by scientists on millions of educational videos from the Internet that showed over 100,000 different people talking. From this dataset, Speech2Face learned associations between vocal cues(声带) and certain physical features in a human face, researchers wrote in a new study. The AI then used an audio clip to model a photorealistic face matching the voice.
However, the tool was far from perfect. Speech2Face turned out “mixed performance” when confronted with language variations. For example, when the AI listened to an audio clip of an Asian man speaking Chinese, the program produced an image of an Asian face. However, when the same man spoke in English in a different audio clip, the AI generated the face of a white man, the scientists reported.
Thankfully, AI doesn’t know exactly what a specific individual looks like based on their voice alone. Voice privacy otherwise would be a concern like face recognition for us. The neural network recognized certain markers in speech that pointed to gender(性别), age and ethnicity(种族), features that are shared by many people, the study authors reported.“As such, the model will only produce average-looking faces,” the scientists wrote. “It will not produce images of specific individuals.”

3 . Dr. Sun Yat-Sen Classical Chinese Garden
Hidden amongst the shops and cafes of colorful Chinatown at 578 Carrall Street, the walled Dr. Sun Yat-Sen Classical Chinese Garden is a little oasis(乐土) in the city of Vancouver, BC. Popular with locals looking for a quiet walk, tourists looking for an interesting attraction, and film crews searching for locations that look like China, the Chinese Garden is top of most people’s lists for a shot of nature in the heart of the city. Dr. Sun Yat-Sen Park is a public garden that features a lily pond, pagoda(佛塔) and winding pathways — it’s open to the public during daylight hours and has no admission fee. The museum part of the park has an admission fee of $12 from October to April ($14 from May to September) and is open daily, apart from Mondays and Fridays from November 1 to April 30. Explore independently or take one of the 45-minute guided tours that are included in your admission fee to find out more about symbolism in the garden.
Entrance to the garden is at 578 Carrall Street — the public entrance is via the gate in the courtyard and the museum entrance is through the door next to it. Chinatown is within walking distance of most downtown hotels and is served by TransLink buses and the SkyTrain system, which stops at the nearby Chinatown-Stadium station.
Educational events run throughout the year and the garden hosts musical events, art exhibits and author talks, as well as festivals, Halloween celebrations and special one-off concerts. Traditional tea service, and calligraphy(书法) workshops take place all year round, but the garden’s biggest celebration comes during the Chinese Lunar New Year in February. Lanterns light up the garden for three weekends of fun, when the garden is magically transformed for this traditional Chinese festival.

Tears are good for your eyes. In fact, without them, your eyes wouldn’t even be able to move. Some people say tears help us in other ways, too. Maybe you know someone who likes to watch sad movies in order to “have a good cry”. It hasn’t been proven, but tears may be good not only for your eyes but also for your emotional health as well.
We generally only notice tears when we cry, but we have them in our eyes all the time. Tears affect how we see the world while at the same time protecting our eyes from it. Without this liquid covering them, our eyes would be at risk of infection. In addition, we need tears in order to see. The cornea (角膜) of the eye does not have a perfectly smooth surface. Tears fill in the holes in the cornea and make it smooth so that we can see clearly. Without tears, the world would look very strange to us.
There are three types of tears, and they are called basal, reflex, and emotional tears. These three types are different not only in purpose but also in composition.
Tom Lutz, the author of Crying: The Natural and Cultural History of Tears, writes, “Throughout history, and in every culture, ... everyone everywhere cries at some time.” Even men and women who say they never cry can usually remember crying as children. Most of us probably think it’s normal for men or women to cry at certain times, and at such times, we may even encourage them to cry. For example, it’s no surprise when someone cries during a sad movie, and we often expect people to cry when a family member dies. However, we don’t always take this view of tears. Sometimes adults who cry — or even children who do — lose the respect of others. For example, what would you think of an adult who cried over losing a card game? Most people are aware of the social rules about when, where, and why it’s OK to cry. These rules generally differ for children and adults, and often for men and women. They depend on things such as family, culture, and religion, and they change over time.
Some people think it’s not just OK to cry but actually healthy to let the tears flow. Doctors in Greece over 2,500 years ago thought that tears came from the brain and that everyone needed to let them out. Today, many people still believe in getting tears out. They say that through crying, we get rid of emotions we have stored up, which is good for our mental health. Some people report that they feel better after crying. This could be because of the chemicals in emotional tears. One chemical is a type of endorphin, a painkiller that the body naturally produces. Emotional tears increase the amount of endorphin that gets to the brain because tears flow from the eye into the nose and pass to the brain that way. This painkiller may make a person less aware of sad or angry feelings, and that could explain why someone feels better after “a good cry”.

2. How do tears help us see clearly?
3. How many kinds of tears do we have?
4. Please list at least two things that are related to the social rules of crying.
5. In which country did doctors over 2,500 years ago believe that tears came from the brain?

DJ: Hello. A lot of you have probably just got your A-levels and you’re looking forward to going to university. But more and more young people are deciding to take a gap year before they start their degrees. Today I’m talking to a group of young people who’ve all decided to take a year out before they go to university. What are they going to do? Rosie? What are your plans?
Rosie: I’m going to work in a department store.
DJ: Why do you want to do that?
Rosie: Two reasons really. I’m going to study Management at university and this will give me the chance to find out what it’s like to work in a big organization. And I’ll also be able to earn some money.
DJ: What about you, Christopher?
Christopher: I’m going to do community work with a conservation group. I think it’ll be good to do something really useful. And I’ll meet a lot of interesting people, I’m sure.
DJ: Will you get paid for it?
Christopher: Well, we won’t get rich doing it, but we’ll be all right. We’ll get about £20 a week plus food and accommodation.
DJ: Helen, what are you going to do?
Helen: I’m going to travel around Europe.
DJ: Are you going to work there?
Helen: I hope so, or I’ll have to come home again. I might try and get a job—you know—in a hotel or something like that.
DJ: Why do you want to do it?
Helen: Well, mainly because it’ll be a change. After all, I’ve been at school for 13 years. I just want to do something different. It’ll give me new experiences and I’ll need to be more independent.

A concert violinist went to New York City to play at Carnegie Hall. It was his one visit to the city, so he got lost on the way from his hotel to the concert. After wandering up or down several streets, he decided to ask for directions. “Excuse me,” he said to a woman on the corner. “How do I get to Carnegie Hall?” The woman looked at the man hold his violin case and answered, “Practice, practice, practice.”
In this old joke, “get to Carnegie Hall” has two meanings: (1) arrive at the building called Carnegie Hall; (2) reach the top of the music profession, symbolized by Carnegie Hall. To perform at Carnegie Hall is a honor for any musician. It’s the highlight of his or her career. It true takes a lot of practice and hard work to be good enough to play at Carnegie Hall.
Carnegie Hall was built by Andrew Carnegie, one of the richest men of his time. It opened in May of 1891. It’s famous for its superb acoustics (音响设计), which make it a wonderful place to both perform and listen to music-all type of music. The famous Russian composer Tchaikovsky played there, and so do the Beatles.
Since the opening night over 100 years ago, many prominent classical, jazz, and pop musicians performed at Carnegie Hall. No matter what they arrived on the night of their performances such as by subway, taxi, or on foot, they all got to there by dedication to their art, talent-and practice, practice, practice.
