--I am sure Mary will win the first place in the coming competition.

--I think so. She ________ for it for months.

A. has prepared      B. has been preparing

C. had prepared      D. prepared

 

B 【解析】 试题分析:考查时态。句意:--我相信玛丽会在接下来的比赛中获得第一名。--我也这样认为,她已经准备好几个月了。for+一段时间,与完成时连用,排除D;根据句意可知,这里说的是现在的情况,排除C;现在完成进行时表示过去的动作对现在造成了影响,并有可能继续下去。根据第一句可知,比赛还没开始,说话时,玛丽仍然在做准备工作,因此,用现在完成进行时最恰当,故选B。 考点:考查时态

Making Peace with Your Parents

As a teen, you’re going through big changes physically and mentally. Your interests are expanding.

1.      

Here is the challenge: Kids need to explore the world in new ways, and parents need to protect them from the dangers that are out in that world. These conflicts can easily set off fireworks in otherwise calm houses. Sometimes conflicts can’t be avoided. But by paying attention to the building blocks of successful relationships, you can work towards making home a happy and healthy place for you and your parents.

For instance, try to find a time to talk when your parents are not angry, tired, distracted, or hungry. A good time to talk is when you’re all relaxed. Timing is everything. If the conversation begins to turn into an argument, you’d better calmly and coolly ask to stop the conversation -- for now. 2.       Listen to what your parents are saying, and repeat it back to them. This shows them that you’re listening.     3.       Respect is the building block of good communication. People who respect each other and care about each other’s feelings can disagree without things getting ugly.     4.            How do you build trust? Trust comes by actually doing what you say you’re going to do. Some teens find that doing fun activities with their parents can improve their relationships. Sometimes we forget that parents are more than rule-makers—they’re interesting people who like to watch movies, and go shopping—just like their teenagers!

What do you do if you are trying your best, but your relationship with your parents continues to be rocky?     5.           You can find supportive adults, such as a teacher or a coach, who can lend an ear.

Remember you can only change your own behavior; your parents are the only ones who can change theirs.

A. It also gives them a chance to clear things up if you’re not on the same page.

B. You can pick it up again when everyone’s more relaxed.

C. And then you’ll be able to accept what your parents say.

D. Faced with the challenge, children don’t know what to do.

E. You are more likely to get along with your parents and have more independence if your parents believe in you.

F. And your desire to take control of your own life is growing.

G. You may consider seeking outside help.

Why texting harms your IQ

The regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana (大麻). That is the statement of researchers who have found that tapping away on a mobile phone or computer keypad or checking for electronic messages temporarily knocks up to 10 points off the user’s IQ. This rate of decline in intelligence compares unfavorably with the four-point drop in IQ associated with smoking marijuana, according to British researchers, who have described the phenomenon of improved stupidity as “infomania”. The research conducted by Hewlett Packard, the technology company, has concluded that it is mainly a problem for adult workers, especially men.

It is concluded that too much use of modern technology can damage a person’s mind. It can cause a constant distraction of “always on” technology when employees should be concentrating on what they are paid to do. Infomania means that they lose concentration as their minds remain fixed in an almost permanent state of readiness to react to technology instead of focusing on the task in hand. The report also added that, in a long term, the brain will be considerably shaped by what we do to it and by the experience of daily life. At a microcellular level, the complex networks of nerve cells that make up parts of the brain actually change in response to certain experiences.

Too much use of modern technology can be damaging not only to a person’s mind, but to their social relationship. 1100 adults were interviewed during the research. More than 62 per cent of them admitted that they were addicted to checking their e-mails and text messages so often that they scrutinized work-related ones even when at home or on holiday. Half said that they always responded immediately to an email and will even interrupt a meeting to do so. It is concluded that infomania is increasing stress and anxiety and affecting one’s characteristics. Nine out of ten thought that colleagues who answered e-mails or messages during a face-to-face meeting were extremely rude.

The effects on IQ were studied by Dr. Glenn Wilson, a psychologist at University of London. “This is a very real and widespread phenomenon,” he said. “We have found that infomania will damage a worker’s performance by reducing their mental sharpness and changing their social life. Companies should encourage a more balanced and appropriate way of working.”

1.We can learn from the passage that “infomania” ______.

A. has a positive influence on one’s IQ

B. results in the change of part of the brain

C. lies in the problem of lack of concentration

D. is caused by too much use of modern technology

2.The research mentioned in the passage is most probably about ______.

A. the important function of advanced technology

B. the damage to one’s brain done by unhealthy habits

C. the relevance between IQ and use of modern technology

D. the relationship between intelligence and working effectiveness

3.The underlined word “scrutinized” probably means “______”.

A. examined carefully   B. copied patiently

C. corrected quickly    D. admitted freely

4.Which of the following shows the structure of the passage?

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 of 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 were 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 we 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 the 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 Para.1 probably means _____.

A. early            B. sweetly

C. quickly         D. carefully

2.Some cats and dogs may fight when ______.

A. they are cold to each other

B. they look away from each other

C. they are introduced at an early age

D. they misunderstood each other’s signals

3.It is suggested in Para.4 that cats and dogs ______.

A. have common interests

B. have a common body language

C. are less different than we thought

D. are less intelligent than we 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.
