1 . Overhear any conversation or pay close attention to your own, and you will hear laughter. You will probably also notice that, more often than not, the laughter is in response to something that was not very funny—or was not funny at all. Take Hillary Clinton’s strategic laughter during heated exchanges with Donald Trump in the presidential debates.
In one research in my Vocal Communication Lab at UCLA, we played recorded laughs to listeners and asked them, “Is this laugh ‘real’ or ‘fake’?” Our recorded laughs were either taken from real conversations between friends in a laboratory setting, or produced by request, also in the lab. It turned out that about 70 per cent of the listeners were able to tell the “real” laughs from the “fake” ones. Quite a few fake laughs sound pretty good, but why are fake laughs not as convincing as we expect? We can detect part of a laugh that is hard to fake—and that part has to do with the control of our breath.
Laughs could essentially be broken up into two different vocalisation (发声) systems: speech and emotion. Although both kinds of laughs are vocalised as “ha-ha-ha,” the intermittent breaths a person takes in—between the sounds give away a fake laugh. Real laughs have a higher proportion of breathy parts in between. Think about every time you force a laugh. You have to actually say the “ha-ha-ha,” and probably never consider how you breathe while doing it.
A fake laugh is basically an imitation of a real laugh. If you slow down a real laugh about two and a half times, it sounds like an ape (猿). But a slowed fake laugh sounds more like human speech. We put this observation to the test with the slowed-down versions of the laughs used for our first experiment, and asked participants whether the recordings were from a human or an animal. Though they couldn’t tell the origin of the real laugh, they were able to tell that the fake laugh came from a human.
Real laughs are produced by an emotional vocal system that humans share with all primates (灵长目动物), whereas fake laughs are produced by a speech system that is unique to humans. Laughter in humans likely evolved from play vocalisations in our primate ancestors. If one animal bites another during a rough-and-tumble (小打小闹的) play, it could be taken as an attack. But if they signal while panting (喘气) that they are just playing, the play can continue without being interrupted by an unnecessary real fight. In this way, real laughter reveals our animal nature.

It’s not piano lessons or dance classes. Nowadays, the biggest extra-curricular activity is going to a tutor. “I spend about 800 Canadian dollars a month on tutors. It’s costly,” says Pat, a mother in Canada. However, she adds, “After finding out half my daughter’s class had tutors, I felt like my child was going to fall behind because everyone else seemed to be ahead.”
Shelley, a mother of three, also has tutors constantly coming in and out of her home. “When I used to sit down with my children, it was hard to get them focused. I was always yelling. When I got a tutor once a week, they became focused for one entire hour and could get most of their homework done.”
Tutoring isn’t simply a private school phenomenon. Nor is it geared only toward lower-achieving students. In Canada alone, seven per cent of high school students reported using a tutor in 2010. That increased to 15 per cent last year.
Overall, parents hire tutors because they are worried schools are not meeting their expectations, but there is also a cultural shift. A special value is placed on education in Asia, where tutoring is viewed as an extension of the school day. As a large number of Asians emigrated to the West over the recent years, their attitudes towards education have had an impact.
Another reason for the growth in business is parental frustration and their packed schedules. “A lot of parents just don’t have time to help their children with homework,” says Julie Diamond, president of an American tutoring company. “Others couldn’t help their children after Grade 3.”
There has been a shift in the attitudes, too. “Children used to get bullied (欺侮) for having a tutor, ” Diamond says, “Now it’s becoming the norm to have one. ”
Children don’t seem to mind that they have a tutor. One parent feels surprised that so many of her child’s classmates have tutors. “For the amount we pay in tuition, they should have as much extra help as they need,” she says. Still, she’s now thinking of getting a tutor. Why Her daughter has actually asked for one?

To have a second child or not, this is a question.
A concern about having only one child is whether one child necessarily means a lonely child. Many parents of only child feel guilty of their decision. There are no other children in the family for the child
Another common argument is
Despite these arguments, the number of parents choosing to have only one child is
Advocates (支持者) of single-child families argue that there are advantages for the child
However, there is no simple answer to the question of
We see it everywhere. A tired parent, at the end of a stressful day, loses it — and a child suffers. We’d like to help if we could, but we hesitate. Is it our business to intervene (干涉)? And if we do, will we embarrass and offend the parent, making him or her even more angry with the child? Isn’t it wiser to walk past without comment? After all, none of us is a perfect parent.
There seems to be a common assumption in our society that intervening on behalf of a child in a public place is necessarily hurtful and critical. It needs to be neither. There is a world of difference between hurtful criticism (“How dare you treat your child like that?”)and helpful intervention done in a caring way (“It can be really hard to meet their needs when you’re so busy. Is there anything I can do to help?”)There is nothing essential in intervention that requires one to be offensive.
My friends and I have witnessed some really harmful acts: hitting, severe verbal abuse, hurtful comparisons to brothers and sisters, and so on. These children accept this treatment because they are too helpless and inexperienced to stand up for themselves. That emotional abuse (虐待) leaves no outward scars should not excuse us from helping these children. Those of us who can recognize damaging treatment have an obligation to step in.
There is one more reason for intervening that is nearly always overlooked in these discussions, but which I consider to be the most significant: the lifelong effect it can have on the child. Many adults in counseling sessions still recall with gratitude the one time that a stranger stepped in on their behalf, and how much it meant: that someone cared, and that the child’s feelings of anger and frustration were recognized and accepted. These adults have stated to me that this one intervention changed their lives and gave them hope. Are we to bypass the opportunity to make such a big difference in the life of a child?

10 . Help Migrant Workers
There is nothing like going home. More so if it is for the Spring Festival family reunion. For a migrant worker it perhaps means even more. To be able to set out on a homeward journey with money from a year’s toil in his pocket is the best thing he can think of.
About 200 million migrant workers nationwide are something left behind by economic reforms and opening up due to their contributions in the past three decades. It is almost impossible to imagine life in these places without them. However, they still form a disadvantaged group. Their rights are violated in different forms. Among other things, unpaid salaries are the most painful of such violations that are likely to drive a migrant worker to desperate actions.
It is good news that quite a number of local governments have organized special task forces to conduct inspections in those labor-intensive enterprises to make sure they have paid their migrant workers in a timely and fair manner. Construction commissions in almost all provinces have published hotlines for farmer-turned-construction workers to lodge complaints against their employers for withholding their salaries.
A.Some have reportedly climbed up chimneys to jump to their death unless they get their defaulted salaries. |
B.It is something every Chinese look forward to as the traditional gala draws near. |
C.Unfortunately, weeks preceding the Spring Festival have turned out to be hard times for migrant workers. |
D.Hopefully, these efforts will send more workers on a happy journey home for the Spring Festival with their salaries in their pockets. |
E.However difficult the situations they are in, it is too cruel and unfair for employers to hold back salaries they should pay their migrant workers. |
F.Objectively speaking, governments at various levels have done a great deal in helping these workers recover their defaulted salaries. |
