Cotton farmers in some Indian villages are busily buying Coca Cola and Pepsi, believing that the sugar in the fizzy (有泡沫的) drinks kills pests.

Farmers say scientists advised them to mix pesticides with a sugary juice to control pests, and they found the mixture cheaper and more effective than pure chemicals — although soft drink makers and scientists dismissed the remarks. N. Hamunayya, who has become a famous person in his village in the southeastern state of Andhra Pradesh, said his crop survived an attack of pests which had resisted other pesticides. “We found that all the colas had uniform effect on pests. The pests became dead and fell to the ground,” he said. He said the drinks had all the elements they needed: they were cheaper, sticky, fizzy, and attracted ants, which ate the young of the pests. But Thinupathi Reddy, assistant director of the Regional Agri Research Station, Guntur, says tests had proved such results wrong. “We conducted some field trials on cotton crop at our research station. There was no obvious productivity or destruction of pests,” he says.

Statements from Pepsi and Coca Cola said there was “no scientific basis” for this_practice. But their dealers are enjoying increasing sales. Mantan Wall, who sells soft drinks in 17 villages in the region, said sales rose up, thanks to the farmers. “For the 10 days between August and September I had successful business. Instead of just 30 cases (each containing a dozen one litre bottles) of cola, I started selling almost 200 cases,” he said. “We expected the sales to drop after the news over pesticide residues (残留) in the cola drinks. Now I have to keep extra supply for the cotton farmers,” he said.

In February, an Indian environment group made a report saying drinks made by Coca Cola and Pepsi contained pesticides and called for tougher safety standards. The US firms strongly rejected the findings of the New Delhi?based Centre for Science and Environment and said their products were safe.

Wisdom teeth are normally the last teeth to appear.This usually happens when people are in their late teen years or early twenties,in other words,when they are older and wiser.

Wisdom teeth can grow into place normally and never cause a problem.But often there is not enough room for them in the mouth;they might crowd other teeth.Sometimes they even push sideways through the gums (齿龈).

An impacted wisdom tooth is one that fails to completely rise through the gums.Wisdom teeth that only partly break through can leave space for bacteria to enter around the teeth.Infection (感染) is a risk in these cases.

Wisdom teeth that are not well lined and become impacted are often removed.The American Dental Association says removal is generally advised when wisdom teeth only partly break through the gums.Removal is also advised if there is a chance that wisdom teeth ate poorly lined.The best time to remove is before the teeth cause any problems or pain.Young adults are the best candidates for wisdom teeth removal.

But why do we have wisdom teeth if we often need to get them removed? One theory has to do with our diets.Scientists say the diet of ancient humans probably required more chewing teeth.Life was probably a little rougher on the teeth back then,too.So it was good to have extras.

1.According to the passage,which of the following statements is NOT true?

A.Just older and wiser people can have wisdom teeth.

B.Wisdom teeth can cause problems if not in their right place.

C.Impacted wisdom teeth can’t grow out of the gum fully.

D.Wisdom teeth that only partly break can get bacterial infections.

2.Wisdom teeth should be removed ________.

A.when they break through the gums

B.when they are below the gums

C.if they are not well lined or get impacted

D.if they take up enough room in the mouth

3.We can learn from the passage that________.

A.impacted wisdom teeth have the risk of getting infected

B.ancient humans need chewing teeth because of their happy life

C.older adults are the best candidates for wisdom teeth removal

D.more chewing teeth are needed for the diet of modern humans

“I’ve changed my mind.I wanted to have a telescope,but now I want my dad back.” Lucien Lawrence’s letter to his father for Christmas written after his father had been knifed to death outside his school gate,must have touched everyone’s heart.Lucien went on to say that without his father he couldn’t see the stars in the sky.When those whom we love depart from us,we cannot see the stars for a while.

But Lucien,the stars are still there,and one day,when you are older and your tears have gone,you will see them again.And,in a strange way,I expect that you will find your father there,too,in your mind and heart.I find that my parents,who died years ago,still figure in many of my dreams and that I think of them perhaps more than I ever did when they were alive.I still live to please them and I’m still surprised by their reactions.I remember that when I became a professor,I was so proud,or rather so pleased with myself that I couldn’t wait to cable my parents.The reply was a long time in coming,but when it did,all my mother said was “I hope this means that now you will have more time for the children!” I haven’t forgotten.The values of my parents still live on.

It makes me pause and think about how I will live on in the hearts and minds of my children and of those for whom I care.Would I have been as ready as Philip Lawrence have been to face the aggressors,and to lay down my life for those in my care?How many people would want me back for Christmas?It’s a serious thought,one to give me pause.

I pray silently,sometimes,in the dead of night,that ancient cry of a poet “Deliver my soul from the sword,and my darling from the power of the dog.” Yet I know the death comes to us all,and sometimes comes suddenly.We must therefore plan to live forever,but live as if we will die tomorrow.We live on,I’m sure,in the lives of those we love,and therefore we ought to have a care for what they will remember and what they will treasure.If more parents knew this in their hearts to be true,there might be fewer knives on our streets today.

Many of us still tend to think that emotions can affect reasonable thought,and sometimes land us in trouble. But in recent years psychologists have taken quite a different view. Keith Oatley,Professor of Psychology at Glasgow University,is involved in the research which shows the fundamental importance of emotions.

He believes we are very ambivalent about them:we think of our emotions as being unreasonable,but we also consider them as essential to being human.For example,Mr Spock,a character in the television series Star Trek,is super?intelligent and he has no emotions at all.However,he is never made captain of the spaceship.Maybe,this is because Mr Spock is not the kind of person you can share your feelings with—a person who shows his emotions.

As Professor Oatley points out,our emotions have very important functions,for example,fear.If we cross the road and a car approaches,we usually stop moving or step back.We stop what we are doing,check what we have done and pay very careful attention to the environment.The emotion of fear makes us take this small series of actions which,on average,help preserve our safety.

On the other hand,if things are going well and small problems come up,we find we can solve them with the resources we have to hand.As a consequence,we tend to feel happy and usually continue doing the job.

Anger is an emotion that tends to occur when someone is preventing us from doing something.Then this small “kit” of reactions enables us to prepare ourselves to be quite aggressive to that person,or to try harder,and so on.

Professor Oatley believes emotions generally occur at these important moments in actions.With fear and anger our emotions make us decide to start doing something else,while with happiness they “suggest” we continue what we are already doing.

1.What’s Keith Oatley’s opinion about emotions?

A.They affect reasonable thought.

B.They get us into trouble.

C.They are helpful to us.

D.They are reasonable.

2.What does the underlined part “we are very ambivalent about them” in Paragraph 2 mean?

A.We have contradictory feelings towards emotions.

B.We have similar ideas of emotions.

C.We are quite clear about emotions.

D.We can do nothing about emotions.

3.Which of the following is NOT mentioned in the passage?

A.Fear helps us to be careful about our surroundings.

B.Happiness inspires us to continue what we are doing.

C.Anger may urge us to make greater efforts.

D.Anger tends to do us more harm than good.

4.It can be inferred from the passage that________.

A.we must control our emotions in daily life

B.emotions play a more important part than we realize

C.positive emotions such as love and joy are good for us

D.negative emotions make us continue what we are doing

Can dogs and cats live in perfect harmony in the same home? People who are thinking about adopting a dog as a friend for their cats are worried that they will fight. A recent research has found a new recipe for success. According to the study, if the cat is adopted before the dog, and if they are introduced when still young (less than 6 months for cats, a year for dogs), it is highly probable that the two pets will get along swimmingly. Two?thirds of the homes interviewed reported a positive relationship between their cat and dog.

However, it wasn't all sweetness and light. There was a reported coldness between the cat and dog in 25% of the homes, while aggression and fighting were observed in 10% of the homes. One reason for this is probably that some of their body signals are just opposite. For example, when a cat turns its head away it signals aggression, while a dog doing the same signals submission.

In homes with cats and dogs living peacefully, researchers observed a surprising behavior. They are learning how to talk each other's language. It is a surprise that cats can learn how to talk “Dog”, and dogs can learn how to talk “Cat”.

What's interesting is that both cats and dogs have appeared to develop their intelligence. They can learn how to read each other's body signals, suggesting that the two may have more in common than was previously suspected. Once familiar with each other's presence and body language, cats and dogs can play together, greet each other nose to nose, and enjoy sleeping together on the sofa. They can easily share the same water bowl and in some cases groom (梳理) each other.

The significance of this research on cats and dogs may go beyond pets — to people who don't get along, including neighbors, colleagues at work, and even world superpowers. If cats and dogs can learn to get along, surely people have a good chance.

1.The underlined word “swimmingly” in Paragraph 1 is closest in meaning to “________”.

A.early B.sweetly

C.quickly D.smoothly

2.What is found surprising about cats and dogs?

A.They eat and sleep together.

B.They observe each other's behaviors.

C.They learn to speak each other's language.

D.They know something from each other's voices.

3.It is suggested in Paragraph 4 that cats and dogs ________.

A.have common interests

B.are less different than thought

C.have a common body language

D.are less intelligent than expected

4.What can we human beings learn from cats and dogs?

A.We should learn to live in harmony.

B.We should know more about animals.

C.We should live in peace with animals.

D.We should learn more body languages.
