Recording 2 人类婴儿的能力
In last week’s lecture， we discussed the characteristics of the newly born offspring of several mammals. You probably remember that human infants are less developed physically than other mammals of the same age. But ［19］ in today’s lecture， we’ll look at three very interesting studies that hint at surprising abilities of human babies.
In the first study， three-year-olds watch two videos shown side by side. Each featuring a different researcher， one of whom they’d met once two years earlier. The children spend longer watching the video showing the researcher they hadn’t met. This is consistent with young children’s usual tendency to look longer at things that aren’t familiar. And really this is amazing. It suggests the children remember the researcher they’ve met just one time when they were only one-year-olds. Of course， as most of us forget memories from our first few years as we grow older， this early long-turn memories will likely be lost in subsequent years. Our second study is about music， for this study researchers play music to babies through speakers located on either side of a human face. They waited until the babies got bored and inverted their gaze from the face. And then they change the mood in the music either from sad to happy or the other way around. This mood switch made no difference to the three-month-olds; but for the nine-month-olds， it was enough to renew their interest and they started looking again in the direction of the face. ［20］ This suggests that babies of that age can tell the difference between a happy melody and a sad tune.
Our final study is from 1980， but it’s still relevant today. In fact， ［21］ it’s one of the most famous pieces of research about infant emotion ever published. The study involved ordinary adults watching video clips of babies nine months or younger. In the video clips， the babies made various facial expressions in response to real life events including playful interactions and painful ones. The adult observers were able to reliably discern an assortment of emotions on the babies faces. These emotions included interest， joy， surprise， sadness， anger， disgust， contempt， and fear.
Next week， we’ll be looking at this last study more closely. In fact， we will be viewing some of the video clips from that study. And together， see how well we do in discerning the babies’ emotions.
Questions 19 to 21 are based on the recording you have just heard.
Q19： What are the three interesting studies about？ D） Abilities of human babies.
Q20： What does the second study find about nine-month-old babies？ A） They can distinguish a happy tune form a sad one.
Q21： What is the 1980 study about？ B） Baby emotions.

Recording 3 工作中过于团队合作的坏处
Today I’d like to talk about the dangers of being too collaborative. Being a good team player is a central skill in our modern workplace. The ability to work well with others and collaborate on projects is a sought-after ability in nearly every position. However， placing too much emphasis on being a good team player ［22］ can negatively affect your career growth. Don’t be overly focused on gaining consensus. Don’t be too concerned with the opinions of others. This can hinder your ability to make decisions， speak up and gain recognition for your individual skills and strengths. Some people are too subordinate to others’ opinions， too focused on decision consensus， too silent about their own point of view， too agreeable to take things on when they don’t have time or energy. This leads to building a brand of underconfident， submissive， low-impact non-leaders and hampers their growth and career advancement.
［23］ Collaboration certainly makes your individual competencies and contributions more difficult for outsiders to identify. Collaborative projects mean you’re sharing the spotlight with others. Outsiders may then find it difficult to determine your contributions and strengths. This may end up costing you opportunities for promotions or pay raises. You certainly shouldn’t ditch teamwork， but how can you avoid the hazards of being an over-collaborator？

Working in a team can have huge benefits. Your team may have repeated successes and often gain recognition. ［24］ You then have more opportunities to expand your professional network than if you worked alone. However， finding a balance between team efforts and individual projects that give you independent recognition is important for making a name for yourself and providing opportunities for advancement.
Be selective in who you work with. This will maximize the benefits and minimize the downsides of being a team player. Collaborate with people who have complementary expertise. Select projects where there’s potential for mutual benefit. Perhaps you’re bringing your unique knowledge and gaining access to someone else’s professional network， or maybe you’re able to learn a new skill by working with someone. Seek out your teammates purposefully rather than jumping on every new group project opportunity. ［25］ When we’re too collaborative， we want everyone to agree with a decision before we proceed. This can create unnecessary delays as you hold meetings trying to achieve consensus. It’s fine to be collaborative when seeking input. But put a deadline on the input stage and arrive at a decision， even if it’s a decision that doesn’t have consensus.
Questions 22-25 are based on the recording you have just heard.
Q22. What does the speaker say about being over collaborative？ B） It may hinder individual career advancement.
Q23. What does the speaker say about people engaged in collaborative projects？ C） They may find it hard to get their contributions recognized.
Q24. How do people benefit from working in a team？ A） They can enlarge their professional circle.
Q25. Why is it undesirable to spend too much time trying to reach consensus？ B） It may prevent making a timely decision.
