1 . We love letters. Just as John Donne, a poet, _________ it, “Letters, to me and my friends mean _________ greetings; they get souls together. Thanks to letters, friends who are _________ speak.” He wrote these words nearly 400 years ago. Today, in the age of instant text message, social media, and email, they _________ ring truer than ever, because writing or receiving a letter has become such a _________ event.

A UK-wide survey undertaken by Sunday Times suggests that one in four of us has not _________ a letter for at least 10 years. That’s ten years without the bitter-sweet _________ of pacing the floor waiting for the _________; ten years without recognizing the handwriting on the envelope and eagerly _________ the letter to read its content.

We ____________ not get them any more, but we still love handwritten letters. In the same survey, one third of ____________ people interviewed say that they ____________ the content of sentimental (充满情感的) letters. Shouldn’t we make ____________ to give our friends and families what they will treasure forever? Ann Bickley went online in 2013 and offered to handwrite a letter to anyone who ____________ her. Her website received 50,000 ____________ in its first three months. Five years later, she is still the main ____________ behind one-million-lovely-letter.com and has personally written 4,000 letters offering hope and ____________ to strangers.

The thought behind a letter ____________ as much as its contents. “I never tell anyone that ____________ is going to be OK,” Ann Bickley says, “I am letting someone know that there is someone in the world who ____________ them.”

Who wouldn’t love to receive a letter like that? Let’s get writing!

2 . Have you ever wondered how the trainers at Sea World get the 19,000-pound whale to jump 22 feet out of water and perform tricks? They get that whale to go over a rope farther out of the water than most of us can imagine.     1    .

So how do the trainers at Sea World do it? The first thing they do is reinforce(强化) the behavior that they want repeated --- in this case, to get the whale to go over the rope.    2    , in a position where the whale can’t help but do what’s expected of it. Every time the whale goes over the rope, it’s given positive reinforcement and gets fed with fish. But what happened when the whale goes under the rope? Nothing — no criticism, no warning and no feedback.     3    .

Positive reinforcement is the key of that simple principle that produces such splendid results. And as the whale begins to go over the rope more often than under, the trainers begin to raise the rope. It must be raised slowly enough so that the whale doesn’t starve.

    4    . Make a big deal out of the good and little stuff that we want consistently. Secondly, under-criticize. People know they need help when they mess up.     5    , people will not forget the event and usually will not repeat it.

So we need to set up the circumstances so that people can’t fail. Over-celebrate, under-criticize…and know how far to raise the rope.

Up to 82 percent of children with healthy mothers are not easy to be obese（肥胖的）, according to research. A mother,     1     has a healthy weight, exercises regularly, eats a healthy diet, doesn’t smoke and only     2    (drink) wine in moderation, is significantly less likely     3    (have)a fat child, scientists say.

And research suggests it could be more to do with nurture(养育)    4     nature, as a mother's lifestyle appears     5    (direct) linked to the health of her child. When both mother and child follow a healthy lifestyle, the risk of obesity     6    (reduce)even more, the study of more than 24,000 children found.

The study examined the medical history and lifestyles of more than 24,000 children aged nine     7     fourteen, born to almost 17,000 women in the US. Researchers looked at the link between overall mother health and likelihood of a child     8    (be) obese.

The mother's health was judged on her height-to-weight ratio(比例), her diet, amount of physical     9    (active), smoking status and how much alcohol she drank. A healthy weight and diet, regular exercise, no smoking and moderate drinking all reduce the chance of a woman having     10     obese child.

4 . We’ve all been there: in a lift, in line at the bank or on an airplane, surrounded by people who are, like us, deeply focused on their smartphones or, worse, struggling with the uncomfortable silence.

What’s the problem? It’s possible that we all have compromised conversational intelligence. It’s more likely that none of us start a conversation because it’s awkward and challenging, or we think it’s annoying and unnecessary. But the next time you find yourself among strangers, consider that small talk is worth the trouble. Experts say it’s an invaluable social practice that results in big benefits.

Dismissing small talk as unimportant is easy, but we can’t forget that deep relationships wouldn’t

even exist if it weren’t for casual conversation. Small talk is the grease(润滑剂) for social communication, says Bernardo Carducci, director of the Shyness Research Institute at Indiana University Southeast. ＂Almost every great love story and each big business deal begins with small talk,＂ he explains. ＂The key to successful small talk is learning how to connect with others, not just communicate with them.＂

In a 2014 study, Elizabeth Dunn, associate professor of psychology at UBC, invited people on their way into a coffee shop. One group was asked to seek out an interaction(互动) with its waiter; the other, to speak only when necessary. The results showed that those who chatted with their server reported significantly higher positive feelings and a better coffee shop experience. ＂It’s not that talking to the waiter is better than talking to your husband,＂ says Dunn. ＂But interactions with peripheral(边缘的) members of our social network matter for our well-being also.＂

Dunn believes that people who reach out to strangers feel a significantly greater sense of belonging, a bond with others. Carducci believes developing such a sense of belonging starts with small talk. ＂Small talk is the basis of good manners,＂ he says.
