Our environment isn’t as green and beautiful as it should be. There are steel(钢铁) monsters blocking out the sun, blowing out dangerous smoke, and letting out poisonous chemicals into rivers, cars producing harmful waste gas, people throwing out waste in a wrong way and all other kinds of sources that ruin the planet. Facing current environmental problems, people need to do their best to save the earth.

You can see many big garbage dustbins in the streets. They’re not there for a show, but for you to drop your waste. We should realize that what we do does count. So next time you get that urge to throw gum or a chocolate package out of the car window, or “accidentally” drop as you walk down the street, ask yourself how much waste you’ve been contributing to the environment with that bad habit going on for years.

At home, the first thing we can do to protect the environment is avoid letting water run continuously and make sure that taps(水龙头)are not leaky(漏的),which would help greatly in scrimping. Another is to use energy-saving lights, and turn them off before you leave the rooms. It is not only energy-saving, but also cuts down electricity costs.

Recycling is a method to make items reusable. Many things you want to throw out can be made into new products through the reproducing process. Use your imagination to come up with ways on things that you can use again.

Pass the message of simple ways to save the environment on to kids. Starting with kids is a good way of teaching the message early in their lives, in the hope that they can carry it forward as they grow older.

With environmental protection awareness in mind, we can do what we can, for the results are to have a big effect on the planet. As long as we do our part, the world is one small step closer to being saved.

Many years ago, when I was fresh out of school and working in Denver, I was driving to my parents' home in Missouri for Christmas. I stopped at a gas station(加油站) about 50 miles from Oklahoma City, where I was planning to stop and visit a friend. While I was standing in line at the cash register(收款台), I said hello to an older couple who were also paying for gas.

I took off, but had gone only a few miles when black smoke poured from the back of my car. I stopped and wondered what I should do. A car pulled up behind me. It was the couple I had spoken to at the gas station. They said they would take me to my friend's. We chatted on the way into the city, and when I got out of the car, the husband gave me his business card.

I wrote him and his wife a thank-you note for helping me. Soon afterward, I received a Christmas present from them. Their note that came with it said that helping me had made their holidays meaningful.

Years later, I drove to a meeting in a nearby town in the morning. In late afternoon I returned to my car and found that I'd left the lights on all day, and the battery(电池) was dead. Then I noticed that the Friendly Ford dealership — a shop selling cars — was right next door. I walked over and found two salesmen in the showroom.

"Just how friendly is Friendly Ford?" I asked and explained my trouble. They quickly drove a pickup truck to my car and started it. They would accept no payment, so when I got home, I wrote them a note to say thanks. I received a letter back from one of the salesmen. No one had ever taken the time to write him and say thank you, and it meant a lot, he said.

"Thank you" — two powerful words. They're easy to say and mean so much.

In today's world of smart phones and laptops, most people have at least one time-telling thing with them. Since these digital products are so common, is time running out for the 500-year-old watch? According to some consumers, the answer is yes. New Jersey teenager Charlie Wollman says a watch is “an extra piece of equipment with no necessary function.” Many young adults think so and use their smart phones to tell time. It is said that fewer young people wear watches today than ten years ago. As a result, some people say that the watch industry is at a crossroads.

However, watchmakers optimistically say that watches redeem popularity when consumers reach their 20s and 30s. By then, they are willing to spend money on a quality watch that doesn’t just keep good time. Fifty years ago, watchmakers took pride in their products’ accuracy. But in recent years, the watch industry has changed itself into an accessory(配饰) business. And today, the image a watch conveys has become more important than the time it tells.

“Complications” — features that go beyond simple timekeeping — are an important part of a watch’s image. Today’s watches offer lots of features that meet almost any personality. These features include compasses, USB drivers, and even other functions that measure the effectiveness of golf swings!

Creativity also plays a key role in designing today’s watches. For example, Japanese watchmaker Tokyoflash makes watches that don’t even look like watches. The company’s popular Shinshoku model uses different color lights to tell time. It looks more like a fashionable bracelet than a watch.

Whether a watch conveys fashion sense, creative talent or a love of sports, consumers want their watches to stand out. Nowadays, everyone has the same kind of gadget(小玩意) in their bags, so people want to make a statement with what’s on their wrists. Will this interest in wrist fashion last? Only time will tell!

1.What can we know from the first paragraph?

A. As most people see, watches are out of fashion.

B. Some people feel that watches have been of no use.

C. The watch industry will close down sooner or later.

D. There are so many choices of watches for teenagers today.

2.According to the passage, what image does a watch convey nowadays?

A. It simply tells time.

B. It appeals to many teenagers.

C. It has many complex functions.

D. It has an impact on creativity and imagination.

3.Japanese watchmaker Tokyoflash is mentioned in Paragraph 4 to ________.

A. show why Shinshoku watches are popular

B. advertise Shinshoku watches made by Tokyoflash

C. tell that today’s watches need more imagination

D. make a comparison between watches and bracelets

D. Watches Are Becoming Less Popular

You wake up in the morning, the day is beautiful and the plans for the day are what you have been looking forward to for a long time. Then the telephone rings, you say hello, and the drama starts. The person on the other end has a depressing tone in his voice as he starts to tell you how terrible his morning is and that there is nothing to look forward to. You are still in a wonderful mood? Impossible!

Communicating with negative people can wash out your happiness. It may not change what you think, but communicating long enough with them will make you feel depressed for a moment or a long time.

Life brings ups and downs, but some people are stuck in the wrong idea that life has no happiness to offer. They only feel glad when they make others feel bad. No wonder they can hardly win others’ pity or respect.

When you communicate with positive people, your spirit stays happy and therefore more positive things are attracted.When the dagger(匕首) of a negative person is put in you, you feel the heavy feeling that all in all, brings you down.

Sometimes we have no choice but to communicate with negative people. This could be a co-worker, or a relative. In this case, say what needs to be said as little as possible. Sometimes it feels good to let out your anger back to the negative person, but all this does is to lower you to that same negative level and they won’t feel ashamed of themselves about that.

Negativity often affects happiness without even being realized. The negative words of another at the start of the day can cling to(附着) you throughout the rest of your day, which makes you feel bad and steals your happiness. Life is too short to feel negative. Stay positive and avoid negativity as much as possible.

1.The purpose of the first paragraph is to ________.

A. make a comparisonB. offer an evidence

C. describe a daily sceneD. introduce a topic

2.How can negative people affect us?

A. By changing our ways of thinking.

B. By telling us the nature of life.

C. By influencing our emotion.

D. By comparing their attitudes to life with ours.

3.Some negative people base their happiness on ________.

A. making other people unhappy

B. other people’s pity for them

C. building up a positive attitude

D. other people’s respect for them

4.According to the passage, to reduce negative people’s influence on us,we are advised to ________.

A. change negative people’s attitudes to life

B. communicate with negative people as little as possible

C. make negative people feel ashamed of themselves

D. show our dissatisfaction to negative people

A Japanese telecom company has released a robot that it says has emotions. But rather than run in fear from it, we’ve welcomed it into our homes: Pepper, the “emotional robot,” sold out within a minute of going on sale.

Created by Aldebaran Robotics and Japanese mobile giant SoftBank, Pepper went on sale to the general public in Japan June 20. It is “the first humanoid(类人的) robot designed to live with humans,” Aldebaran says on its website. Pepper costs about $1,600. And like all good mobile products, there’s a $120 per month data fee, as well as an $80 per month damage insurance fee. According to a news release, Pepper can pick up on human emotions and create his own using a “multi-layer neural(神经的) network.” Pepper’s touch sensors and cameras are said to influence its mood, which is displayed on the tablet-sized screen on its chest.

Pepper will sigh when unhappy, and can go around your house recording your family’s daily activity. Aldebaran says Pepper can feel “joy, surprise, anger, doubt and sadness,” but it doesn’t say how strongly it can feel these emotions. What happens when Pepper is having a bad day? Will it, like many humans, become uncooperative? Will it ask for some time alone? What happens if it figures out that its purpose in life is just to engage in small talk? Thankfully, Pepper is only about four feet tall, with roller balls instead of legs, so if it is angry with and even turns on its owners, you’ll be safe if you can make it upstairs.

Aldebaran says in reality, they’re probably quite a few decades away from artificial intelligence that could generate real emotions. Aldebaran wasn’t immediately available for comment on when Pepper will be available outside of Japan, but additional sales are scheduled for July after the first 1,000 units sell out. SoftBank currently uses the robots in its stores as greeters, and it plans to offer Pepper to other stores in the future. Hopefully “boredom” is not an emotion Pepper can feel.

1.According to the author, Pepper ________.

A.is very popular among customers

B.can not only run but also show fear

C.is going to be sold all over the world

D.can deal with many kinds of housework

2.How much do you need to pay for Pepper’s data and damage insurance fee each year?

A.80 dollars.B.120 dollars.

C.1,440 dollars.D.2,400 dollars.

3.Pepper’s height and roller balls are mentioned to ________.

A.introduce its appearance

B.tell Pepper won’t get angry

C.show that safety isn’t a big issue

D.explain robots have strong emotions

4.What can we infer from the last paragraph?

A.Pepper cannot produce real emotions.

B.Pepper can feel joy, surprise and boredom.

C.Pepper will be sold in other countries next year.

D.Pepper is being used as waiters in some restaurants.
