    Put a group of strangers in a room together, and they'll probably start a conversation. "Hot today, isn't it?" one might say. "You said it." another replies.

Why do we talk so much about the weather? When we meet new people, we don't begin by telling them our life story. We start with small talk, a polite conversation about something like traffic or weather.

    Research suggests that small talk can build new friendships. When we begin conversations with new people, we want to feel comfortable, and so do they. We use small talk to find common interests. Once we have a common interest, a friendship can begin.

    Small talk even helps people get hired. In order to impress at a job interview, you need to bond with the interviewer right away. Proper small talk can make that first impression get you the job.

    So, how can you make small talk lead to a new friendship or job? First off, find common ground. Select something around you that you share with the other person.

    Next, keep the conversation going. Compliment (赞美) the other person to make him or her feel comfortable, and ask questions to show interest.

    Third, keep eye contact (接触). When you look people in the eye, they feel you appreciate what they are saying. It makes you appear honest and builds trust.

    Naturally, shy people might not have enough confidence to start up conversations with strangers. Talking to someone you don't know is not the easiest thing to do! Some experts say with more practice, small talk does get easier.

    Some people avoid small talk because they dislike discussing things like traffic or weather. For them, they are just too small. However, when you think about it, small talk is anything but small. In fact, it is actually a very big deal!

    Shanghai Hengyuanxiang Drama Development Company and Netherlander Worldwide Entertainment signed a deal last November that would see Shimmer (《犹太人在上海》) become the first Chinese musical to have an open-ended run on Broadway in 2019. {#blank#}1{#/blank#}

    Directed by Xu Jun, Shimmer is a musical in both English and Chinese. Shimmer, which tells a story about Jews who fled to Shanghai to escape Nazi persecution (迫害) during World War II, was first shown at the Shanghai Culture Square in 2015. {#blank#}2{#/blank#} The musical's scheduled open-ended run in 2019 will be one of the events to celebrate the 40th anniversary of the establishment of diplomatic relations between China and the United States. With this play being shown on Broadway, the ties between Chinese people and Americans will be firmly strengthened. And through this drama, the audience can feel the charm of Chinese culture.

    {#blank#}3{#/blank#} To deal with the problem, many production companies in Shanghai have pointed out that they should keep striving for improvement by creating more Chinese musicals and by creating more audiences. Currently, those who watch Western musicals in China are limited to a small group — people who have received a university education or have had overseas working experiences, white-collar and even gold-collar workers. There are only a handful of people who understand foreign languages and you have to find a way to motivate the public and get them into the theater.

    {#blank#}4{#/blank#} There has been a handful of successful musical stories in Shanghai. The Chinese editions of Broadway musicals Cats and Mamma Mia, both of which had hundreds of shows across China, are among the top box office hits.

A. What do you think we can do to prevent Chinese musicals from declining in popularity?

B. At that time, the musical was chosen as the opening show for the 17th China Shanghai International Arts Festival.

C. The box office is expected to be twice higher than that of last year, reaching $1 million in total.

D. The small audience size hasn't discouraged local artists from producing outstanding works.

E. The deal is a milestone for Shimmer in its goal to further spread its influence to the world.

F. Despite the huge success of Shimmer, the team is facing a limited market.

    Attachment is not just a connection between two people; it's a bond that involves a desire for regular contact with that person and the experience of distress(悲伤) during separation from that person.

    According to psychologist John Bowilby, there are four critical characteristics of attachment. The first is the desire to be near those with whom we share an attachment since we are happy while staying with them. Attachments also create a safe shelter, meaning that during times of distress, fear, or uncertainty, we may seek out the people we're attached to for care and comfort. Next, attachment figures also offer a secure base for exploration. This is particularly important during childhood. This secure base allows kids to explore the world while they know they can still return to the safety of the attachment figure. Finally, we experience separation distress when parted from an attachment figure. For example, kids tend to become upset when parents have to leave them in the care of others.

    Attachment serves a number of important purposes. For instance, it helps keep babies and children close to their caregivers so that they can avoid potential dangers, which in turn helps boost their chances of survival. However, if a child doesn't form a secure attachment to a caregiver, he or she will suffer from a number of problems including conduct disorder and oppositional -defiant (对立反抗的) disorder. Researchers also suggest that the type of attachment displayed early in life can have a lasting effect on later adult relationships.

    Psychologist Harry Harlow conducted an experiment on social isolation in monkeys. Baby monkeys were separated from their mothers and placed with surrogate mothers (代母). One mother was simply a wire armature (电枢) that held a bottle, while the other mother was covered with a soft terry cloth material. Harlow found that the baby monkeys would receive food from the wire mother, but preferred to spend most of their time with the soft mother. When compared to monkeys that had been raised by their birth mothers, the monkeys raised by surrogate mothers were shyer and more nervous and suffered from social and emotional problems.

All in all, developing secure and healthy attachments early in life is very important. Such attachments play a vital role in our future development.

    Many people know that trash is a big problem on planet Earth. What many people don't know is that trash has become a problem in outer space too. {#blank#}1{#/blank#}

    Statistically, there are more than 22,000 pieces of junk in space around the earth. And these are just the items that we can see from the surface of the earth by telescopes or radars. {#blank#}2{#/blank#}

    Objects, like bits of old space rockets or satellites, move around the planet at very high speeds, so fast that even a very small piece can break important satellites or become dangerous to people, particularly astronauts. If the tiniest piece of junk crashed into a spacecraft, it could damage the vehicle. That's because the faster an object moves, the greater the impact if the object collides with something else.

    To help minimize additional space junk, countries around the world have agreed to limit the time their space tools stay in orbit to 25 years. Each tool must be built to fall safely into the earth's atmosphere, or the mass of gases that surround the earth, after that. {#blank#}3{#/blank#}

    Many scientists are also proposing different ways to clean up space junk. The Germans have been planning a space mission with robots that would collect pieces of space trash and bring them back to Earth so that they can be safely destroyed.

    "In our opinion the problem is very challenging, and it's quite urgent as well," said Marco Castronuovo, an Italian Space Agency researcher who is working to solve the problem. {#blank#}4{#/blank#} Many of these objects are tools that help people use their cell phones or computers.

    "The time to act is now; as we go farther in time we will need to remove more and more fragments," he says.

A. One reason that it's urgent is that countries are sending more and more objects into space.

B. There are also millions of smaller pieces of junk that we can't see.

C. Blowing up older satellites with a missile may create thousands of smaller pieces!

D. In the upper parts of the atmosphere, it will burn up.

E. When two objects in space collide, the two objects break into many smaller pieces.

F. Years of space exploration have left tons of "space junk" in orbit around the planet.
