第3题
Our family lives on a dirt road in rural Vermont.Most mornings, I walk that dirt road
with my two dogs, Matti Dog and Yellow Dog.

Both Matti Dog and Yellow Dog were strays of unknown history.They both showed signs, curling up at sharp voices and fast movement, of having been beaten in their past homes.We got Matti Dog at the pound (走失家畜认领栏), where she was known as Lady.Yellow Dog appeared while my wife and son were traveling in Utah.

In spite of their backgrounds they are simply wonderful dogs.Both stay at home, without requiring a chain, or fence.We don’t need a leash(皮带)on our walks, they stay close to me, and come immediately when I whistle.If I ask them to sit, they do and they stay until released.Yellow Dog does tend to find and carry dead animals on our walk — but hey he is a dog…

Training Matti Dog and Yellow Dog to behave this well took love and 3-4 weeks of daily half-hour exercises of basic obedience(服从).Not much effort but apparently more than many are willing to give.

On this 3-mile walk, we pass about 8 other houses and 15 other dogs.Folks in my neighborhood like dogs! But what is troubling is that 6 of these dogs appear to be chained all the time.I don’t monitor this, but I have walked by at various times of the day and they were always chained.

These poor dogs are castoffs(被抛弃的狗), perhaps a Christmas present now ignored, or maybe they just behave so “badly” that their humans gave up.What does it say about owners that they can’t spend 2-4 weeks half an hour daily to teach their dog how to behave in a way that permits the dog freedom and that helps that dog be a better companion?

I do know some of these folks.They seem decent enough, but here for all passers to see is the failure of their relationship with man’s best friend.

Your dog is a great billboard.The advertisement is about you.

1.What do we know about the two dogs?()

A.They behave badly at home

B.They were Christmas presents

C.They are dirty and ill

D.They were picked up by the family

2.The writer treats his dogs ____________.

A.cruelly

B.with love

C.with a leash

D.strictly

3.The writer thinks the neighbors’ dogs poor because they __________.

A.don’t have freedom

B.are always hungry

C.like to attack people

D.behave badly

4.The writer believes the owners of those poor dogs _____.

A.are poor people

B.don’t know how to train dogs

C.don’t really love their dogs

D.are too busy to care for dogs

5.“The advertisement is about you” means _________.

A.a lot can be learnt about you from your dog

B.an advertisement is made about you

C.you should know a lot about your dog

D.you make an advertisement for your dog

A 4 year Kid, who does not know what an Email or a Chat App is, prays to God: “Hey, Lo
rd, Please make me a smartphone”. This young kid is asking such a wish from God, because he sees that his parents at home are completely glued to this magical device called smartphone and has no time to look up at him. The smartphone is getting more attention in the house than the child. His parents are present there physically, but their minds are somewhere else. It’s so true that this device has become an inseparable part of our day to day life, and we are addicted to it. We will start feeling restless if we do not look to our phone after a few minutes. We react faster to a phone beep or a message compared to a call by a family member from a different room. We all need to come out of this head-down syndrome. We all need to connect and communicate in real world. We need to put this technology to good use and not become a slave. So what shall we do? It’s simple: the solution is called “digital break”. This means, when you return home from work, you simply turn off or mute all your digital devices for a few hours every day, or at least once in a while. What do you do then? You can share your time with the family, chatting with your wife or husband, playing games with your kids, doing things with other family members, etc. in real life. You will soon realize the world outside the smartphone is much more enjoyable

Advertising informs consumers about new products available on the market.It gives us i
nformation about everything from shampoo to tooth-paste to computers and cars.But there is one series problem with this.The "information" is actually very often "misinformation".It tells us the products, benefits but hides their disadvantages.Advertising not only leads us to buy things that we don't need and can't afford, but it also confuses our sense of reality.

Advertisers use many methods to get us to buy their products.One of their most successful methods is to make us feel dissatisfied with ourselves and our imperfect lives.Advertisements show us who we aren't and what we don't have."Why don't I have any dates (约会)?" a good-looking girl sadly asks in a commercial."Here," replies her roommate, "Try Zoom tooth-paste!" Of course she tried it, and immediately the whole football team falls in love with her."That's a stupid commercial," we might say.But we still buy Zoom tooth-paste out of fear of being unpopular and having no friends.

If fear is the negative motive (动机) for buying a product, then wanting a good self-image is the positive reason for choosing it.Each of us has a mental picture of the kind of person we would like to be.For example, a modern young woman might like to think that she looks like a beautiful movie star.A middle-aged man might want to see himself as a strong, attractive athlete.Advertisers know this.They write specific ads to make certain groups of people choose their products.

Advertisers get psychologists to study the way consumers think and their reasons for choosing one brand instead of another.These experts tell advertisers about the motives of fear and self-image.They also inform. them about recent studies with colors and words.They have found that certain colors on the package of an attractive product will cause people to reach out and take that package instead of buying an identical (同一的、 相等的) product with different colors.

Many people believe that advertising does not affect them.They like to think they make wise choices.Unfortunately, they probably don't realize the powerful effect of advertising.They may not clearly understand that advertisers spend billions of dollars each year in aggressive (强有力的) competition for our money, and they are extremely successful.

1.What’s the purpose of advertising()?

A.To introduce people the feature of the goods.

B.To have people to buy new products on the market.

C.To make people know how to use the products.

D.To tell people how to save money while buying goods.

2.One of the disadvantages of advertising is to().

A.lead people to buy bad-quality things

B.make people confused about choosing goods

C.make people buy more things than needed

D.inform. people the products’ benefits

3.Advertisement may make people think that()

A.their lives are not good enough

B.their behaviors are imperfect

C.they don’t have enough money to buy things

D.they look poor without buying advertise goods

4.What can psychologists tell the advertisers()

A.The reasons for bad sale of some goods.

B.What brand is better than others?

C.How to control the qualities of goods.

D.People’s opinions about current colors.

5.It’s implied in the last paragraph that those who don’t believe

advertising().

A.should refuse to buy goods advertised

B.may also be influenced by advertising

C.have more freedom to buy things than others

D.can save money without buying the advertised goods

After a day’s hard work, we need some sleep. During the sleep, the fatigue of the body

disappears and recuperation begins. The tired mind gathers new energy, and the memory improves.

Some adults require little sleep; others need eight to ten hours in every twenty-four hours. Infants sleep sixteen to eighteen hours daily, the amount gradually diminishing as they grow older. Young students may need twelve hours; university students may need ten. A worker with a physically demanding job may also need ten, whereas an executive working under pressure may manage on six to eight. Many famous people have little sleep. Napoleon Bonaparte, Thomas Edison and Charles Darwin apparently averaged only four to six hours a night.

Whatever your individual need, you can be sure that by the age of thirty you will have slept for a total more than twelve years. By the age you will also have developed a sleep routine: a favorite hour, a favorite position, and a rule you need to follow in order to rest comfortably.

Investigators have tried to find out how long a person can go without sleep. Several people have reached more than 115 hours nearly five days. Whatever the limit, it is absolute. Animals kept awake for from five to eight days have died of exhaustion. The limit for human beings is probably about a week.

A、sleep is important for good mental and physical health

A、is hard to imagine

B、will probably be a mental breakdown
