Good morning, everyone. It’s my great honor to be here and give a speech on saving food.

That’s all. Thank you for listening.

4 . Nineteen Eighty-Four, a dystopian novel by George Orwell, was set in a totalitarian state where even the language they use is controlled. Adjectives are forbidden and instead they use phrases such as “ungood”, “plus good” and “double plus good” to express emotions. As I first read this I thought how impossible it would be in our society to have such vocabulary. However, the more I thought about it, the more I realised in its own way it's already happening. I type messages to my friends and alongside each is the obligatory (惯用的) emoji. I often use them to emphasise something, or to not seem too serious, or because this specific GIF conveys my emotions much better than I ever could using just words. And I wonder, with our too much use of emojis, are we losing the beauty and diversity of our vocabulary?

English has the largest vocabulary in the world, with over one million words, but who's to say what it'll be like in the future? Perhaps we will have a shorter language, full of saying “cry face” if something sad happens or using abbreviations like LOL (laugh out loud) or BRB (be right back) instead of saying the full phrase. So does this mean our vocabulary will shrink? Is it the start of an exciting new era? Will they look back on us in the future and say this is where it all began—the new language? Or is this a classic case of the older generations saying, “Things weren't like that when I was younger. We didn't use emoticons to show our emotions?”

Yet when you look back over time, the power of image has always been there. Even in the prehistoric era they used imagery to communicate, and what's even more incredible is that we are able to analyse those drawings and understand the meaning of them thousands of years later. Pictures have the ability to go beyond the usual limits of time and language. Images, be it cave paintings or emojis, allow us to convey a message that's not restrictive but rather universal.

6 . HOW BIG should a business team be?It is an enormously important issue for companies, Teams that are too small may lack the skills required to get the job done:teams that are too big may be impossible to co-ordinate.

Robin Dunbar.an anthropologist at Oxford University,has done a lot of work on primate(灵长目）groups.His argument is that the size of the group is linked to the size of the brain.With their large brains,humans can cope with larger bands,A larger social group has many advantages,allowing for greater protection and specialization.

Whereas 150 is sometimes referred to as the"Dunbar number",the academic himself in fact refers to a range of figures.He observes that humans tend to have five intimate friends,15 or so good friends,around 50 social friends and 150-odd acquaintances.

Running a larger network can be difficult.The armed forces have spent more than 1,000 years experimenting with unit size.A Roman centurion(百天长）oversaw 100.The modern American army company has 180 members.Britain's equivalent numbers 120.These are rough estimates,rather than fixed figures.But it is striking that many group activities seem to be close to a Dunbar number. The Special Air Service of Britain has four-man patrols;when your life depends on it,you need to have absolute trust in your colleagues.As a result,such groups are limited in size.

For much of economic history,work was conducted in small units by peasants,tenant farmers and craftsmen.The coming of powered machinery enabled production at a much larger scale,with workers crowded into factories.These days the rise of the service economy means that workers are no longer concentrated in such large groups.

This may not be a bad thing.It was easy for employees in large factories to regard remote company owners as "them"rather than"us".The modern company may settle on a model with a small group of"core"workers and a larger group of contract workers.The result may be more united within the core staff but the non-core staff may be less well treated.The small core teams may work effectively.The big question will be the effect on morale of those outside those teams.

7 . The expression, "everybody's doing it," is very much at the center of the concept of peer pressure. It is a social influence applied on an individual in order to get that person to act or believe in a(n) ___ way as a larger group. This influence can be negative or positive, and can exist in both large and small groups.

People are social creatures by nature, and so it is hardly ___that some part of their self-respect comes from the approval of others. This instinct explains why the approval of peers, and the fear of ____, is such a powerful force in many people's lives. This instinct drives people to dress one way at home and another way at work, or to answer a simple “fine" when a stranger asks "how are you?" even if it is not necessarily true. There is a(n) _____aspect to this: it helps society to function efficiently, and encourages a general level of self-discipline that ___day-to-day interaction between people.

For certain individuals, seeking social acceptance is so important that it becomes a(n) ___: in order to satisfy the desire, they may go so far as to ___their sense of right and wrong. Teens and young adults may feel forced to use drugs, or join gangs that ____criminal behavior. Mature adults may sometimes feel ___ to cover up illegal activity at the company where they work, or end up in debt because they are unable to hold back the desire to buy a house or car that they can't afford in an effort to ___ the peers.

However, peer pressure is not always negative. A student whose friends are good at ___may be urged to work harder and get good grades. Players on a sports team may feel driven to play harder in order to help the team win. This type of ___can also get a friend off drugs, or to help an adult take up a good habit or drop a bad one.

Although peer pressure is sometimes quite obvious, it can also be so ___that a person may not even notice that it is affecting his or her behavior. For this reason, when making important decisions, simply going with a(n) ___is risky. Instead, people should seriously consider why they feel drawn to taking a particular action, and whether the real ____ is simply that everyone else is doing the same thing.

8 . 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!

In recent years, mobile payment has made its way into people’s life. __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

10 . Technological change is everywhere and affects every aspect of life, mostly for the better. However, social changes brought about by new technology are often mistaken for a change in attitudes.

An example at hand is the involvement of parents in the lives of their children who are attending college. Surveys (调查) on this topic suggests that parents today continue to be “very” or “somewhat” overly-protective even after their children move into college dormitories. The same surveys also indicate that the rate of parental involvement is greater today than it was a generation ago. This is usually interpreted as a sign that today’s parents are trying to manage their children’s lives past the point where this behavior is appropriate.

However, greater parental involvement does not necessarily indicate that parents are failing to let go of their “adult” children.

In the context (背景) of this discussion, it seems valuable to first find out the cause of change in the case of parents’ involvement with their grown children. If parents of earlier generations had wanted to be in touch with their college-age children frequently, would this have been possible? Probably not. On the other hand, does the possibility of frequent communication today mean that the urge to do so wasn’t present a generation ago? Many studies show that older parents - today’s grandparents - would have called their children more often if the means and cost of doing so had not been a barrier.

Furthermore, studies show that finances are the most frequent subject of communication between parents and their college children. The fact that college students are financially dependent on their parents is nothing new; nor are requests for more money to be sent from home. This phenomenon is neither good nor bad; it is a fact of college life, today and in the past.

Thanks to the advanced technology, we live in an age of bettered communication. This has many implications well beyond the role that parents seem to play in the lives of their children who have left for college. But it is useful to bear in mind that all such changes come from the technology and not some imagined desire by parents to keep their children under their wings.
