When people reunite with their loved ones, it's usually all extremely happy moment. But what is their most common response to seeing them again? It may seem strange，but most of the time they break down in tears.

    Now a group of psychologists from Yale University say they have found the reason why, and that crying tears of joy may well be the body's way of keeping emotional balance. “They seem to take place when people are overtaken by strong positive emotions, and people who do this seem to recover better from those strong emotions,” Oriana Aragon, the lead researcher said.

    Aragon and her fellow psychologists looked at hundreds of participants' emotional responses to different things, including happy reunions and cute babies. Many participants said they would react in a negative or aggressive way to the positive things —— to cry at happy moments and want to pinch(捏)a cute baby's face or even tell them “I want to eat you up!” But then researchers found that these people were able to calm down from strong emotions more quickly.

    There are many other examples of times when people respond to a positive experience with a negative emotional reaction. At an exciting concert, fans scream at their idols(偶像). People who have just had a big lottery win are often in floods of tears. “These findings advance our understanding of how people express and control their emotions, which is importantly related to mental and physical health, the quality of relationships with others, and even how well people work together.” said Aragon．

    When I was 12, all I wanted was a signet (图章) ring. They were the "in" thing and it seemed every girl except me had one. On my 13th birthday, my Mum gave me a signet ring with my initials(姓名首字母) carved into it. I was in heaven.

    What made it even more special was that it was about the only thing that wasn't being "replaced". We'd been burnt out in fires that swept through our area earlier that year and had lost everything—so most of the " new" stuff (东西) we got was really just to replace what we'd lost. But not my ring. My ring was new.

    Then, only one month later, I lost it. I took it off before bed and it was missing in the morning. I was sad and searched everywhere for it. But it seemed to have disappeared. Eventually, I gave up and stopped looking for it. And two years later, we sold the house and moved away.

    Years passed, and a couple of moves later, I was visiting my parents' when Mum told me that she had something for me. It wasn't my birthday, nor was it Easter or Christmas or any other gift-giving occasion. Mum noticed my questioning look. " You'll recognize this one," she said, smiling.

    Then she handed me a small ring box. I took it from her and opened it to find my beautiful signet ring inside. The family who had bought our house 13 years earlier had recently decided to do some redecorations, which included replacing the carpets. When they pulled the carpet up in my old bedroom, they found the ring. As it had my initials carved into it, they realized who owned the ring. They'd had it professionally cleaned up by a jeweler before sending it to my mother. And it still fits me.

                                        Do dogs understand us?

    Be careful what you say around your dog. It might understand more than you think.

    A border collie named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also appears to be able to learn new words as easily as a 3-year-old child. Its word-learning skills are as good as those of a parrot or chimpanzee(黑猩猩).

    In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects. Then the owner told the dog to go and fetch one of the items and bring it back. In four tests, Rico got 37 out of 40 commands right. As the dog couldn't see anyone to get clues, the scientists believe Rico must understand the meanings of certain words.

    In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. The owner then told Rico to fetch the object, using a word the dog had never heard before.

    The correct object was chosen in seven out of l0 tests, suggesting that the dog had worked out the answer by process of elimination(排除法). A month later, Rico remembered half of the new names, which is even more impressive.

    Rico is thought to be smarter than the average dog. For one thing, Rico is a border collie, a breed (品种)known for its mental abilities. In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.

    It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your dog every now and then. You might just get a big, wet kiss in return!

    LONDON Tuesday April 11—Dustin Hoffman fan Pamela Crack got the shock of her life when the movie star telephoned her as she was doing her housework.Crack, 58, said she was "flabbergasted" when she picked up the phone and heard the star at the other end.

    "It's not every day you get a Hollywood superstar phoning you when you're doing the housework," Crack told the Sun."It was a moment I'll never forget."

    Hoffman was in the back of a London taxi driven by Crack's husband, Dave, when he made the call after being told Pamela was a fan. Dave Crack later became the star of Hoffman's speech at the Bafta award ceremony Sunday, where the 62-year-old American actor presented the Best Film award.

    "He said to give him a mention," Hoffman told the audience to a burst of laughter. "Cheers Dave."Taxi driver Crack said the Hollywood star was a joy to drive from the moment he got into the taxi eating a cheese and tomato sandwich.

    "I said 'You're that Dustin Hoffman, aren't you?' and he said, 'Yes I am—would you like a sandwich?' I was a bit surprised but I took a sandwich from him and ate it hungrily."

    Idioms are one of the hardest parts of learning a language. For those of you who don't know, an idiom is a phrase which has a meaning, but the meaning is not clear from the words themselves. If you translate an idiom word for word, it sometimes makes no sense at all. They are like puzzles and even native speakers can get confused when someone uses a phrase that they've never heard of.

With that in mind, here are five common English idioms that you can use in a variety of Situations.

⒈Get your act together (Meaning: you need to improve your behaviour/work)

    This might be something your teacher says to you if you score badly in an exam or if you misbehave in class. You can also use it to talk about people in general. For example, if your friend is being mean or nasty for no reason, then you can tell them that they need to get their act together.

⒉Pull yourself together (Meaning: calm down)

    This is a somewhat impolite way of telling someone that they are overreacting and that they need to relax. Only use this if you think the person you are speaking to is getting upset over something insignificant. If your friend tells you that their close relative has died, it is NOT the time to tell them to pull themselves together.

⒊I'm feeling under the weather (Meaning: I'm sick)

    Yes, it's longer and more difficult to say than 'I'm sick', but if your English teacher asks you why you haven't done your homework, he or she is more likely to forgive you if you say that you were feeling under the weather. You may not have done your English homework, but your teacher might be impressed that you know how to make eloquent excuses in a foreign language.

⒋It's a piece of cake (Meaning: it's easy)

    I don't know why this means what it does, but sometimes you just have to accept that English people use weird phrases.

⒌Break a leg (Meaning: good luck!)

    This is perhaps one of the most confusing yet well-known English idioms. If someone says this to you, do not take offence or think they are threatening you; they are just wishing you luck. It is most often used for people wishing success to actors and actresses before they perform on the stage, but it can be said in other situations, too.

    All in all, learning a new language can be challenging. It's definitely not a piece of cake, especially when there are so many confusing idioms. However, with enough hard work and interest, you will succeed in no time. Break a leg!
