Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血壓) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.

Any owner will tall you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress (緊張) levels and blood pressure in people - half of them pet owners –while they performed 5 minutes of mental arithmetic (算術) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did

It best .Those tested with their animal friends had smaller change in blood pressure and returned

Most quickly to baseline heart rates .With pets in the room ,people also made fewer math mistakes

Than when doing in front of other companions. It seems people feel more released (放松)around

Pets, says Allen, who thinks it may be because pets don’t judge.

A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwesterm Memorial Hospital spent a

Or 5% of their body weight .Their dogs did even better,losing an average of 12 poundsmore then

15%of their body weight .Dog owners didn’t lose any more weight than those without dogs but ,say

閱讀下面短文,從短文后各題所給的四個選項(A、B、CD)中,選出可以填入空白處的最佳選項,并在答題卡上將該項涂黑。

Generally speaking, a British is widely regarded as a quiet, shy and conservative (保守) person who is only among those with whom he is familiar. When a stranger is present, he often seems nervous, embarrassed. You have to take a commuter train (通勤車) any morning or evening to the truth of this. Serious-looking businessmen and women sit reading their newspapers or off in a corner; hardly anybody talks, since to do so would be considered quite offensive (冒犯的).

, there is an unwritten but clearly understood code of behavior, which, once , makes the offender immediately the object of .

One of the few things we can say about the British with certainty is that a British takes a(n) to the discussion of their weather and that, if given a chance, he will talk about it . Some people argue that it is because the British weather follows forecast and thus becomes a source of interest to everyone. This may be so. Certainly a British cannot have much in the weathermen, whose predictions, in many cases, to be wrong! The man in the street seems to be as accurate – or as inaccurate – as the weathermen in his .

Foreigners may be surprised at the number of references weather that the British make to each other in the course of a single day. Very often conversational greetings are by comments on the weather. “Nice day, isn’t it?” “Beautiful day!” may well be heard instead of “Good morning, how are you?” the foreigner may consider this exaggerated (夸大) and comic, it is worthwhile pointing out that it could be used to his . If he wants to start a conversation with a British but is to know where to begin, he could do well to mention the state of the weather. It is a(n) subject to which a response may well be of even the most reserved of the British.

Kids will often ignore your requests for them to shut off the TV, start their chores(雜事),or do their homework as a way to avoid following your directions. Before you know it, you’ve started to sound like a broken record as you repeatedly ask them to do their assignments, clean their room, or take out the trash. Rather than saying “Do your chores now.” you’ll be more effective if you set a target time for when the chores have to be completed. So instead of arguing about starting chores, just say, “If chores aren’t done by 4 pm, here are the consequences.” Then it’s up to your child to complete the chores. Put the ball back in their court. Don’t argue or fight with them, just say, “That’s the way it’s going to be.” It shouldn’t be punitive(懲罰性的)as much as it should be persuasive. “If your chores aren’t done by 4 pm, then no video game time until chores are done. And if finishing those chores runs into homework time, that’s going to be your loss.” On the other hand, when dealing with homework, keep it very simple. Have a time when homework starts, and at that time, all electronics go off and do not go back on until you see that their homework is done. If your kids say they have no homework, then they should use that time to study or read. Either way, there should be a time set aside when the electronics are off.

When a kid wears his iPod or headphones when you’re trying to talk to him, make no bones about ithe is not ignoring you, he is disrespecting you. At that point, everything else should stop until he takes the earplugs out of his ears. Don’t try to communicate with him when he’s wearing headphones — even if he tells you he can hear you. Wearing them while you’re talking to him is a sign of disrespect. Parents should be very tough about this kind of thing. Remember, mutual respect becomes more important as children mature.

1.According to the passage, it seldom happens that ________.

Akids turn a deaf ear to their parents’ requests

Bparents’ directions sound like a broken record

Cchildren are ready to follow their parents’ directions

Dparents are unaware of what they are repeating to their kids

2.Parents will be able to deal with their children more effectively if they ________.

Aavoid direct ways of punishment Bmake them do things at their request

Cargue and fight with their children Dallow their children to behave in their own way

3.When the kid is doing his homework, parents ________.

Ashould provide him with a good learning environment

Bcan do whatever they like

Ccan stay aside watching TV

Dmust switch off the power

4.It can be inferred from the passage that ________.

Aparents should take off his headphones when trying to have a talk with their child

Bit will make no difference that a kid is wearing his earplugs while talking to his parents

Cparents shouldn’t give in to their kid when he shows no sign of respect

Dkids’ purposely talking to their parents with iPod gives them a sense of power and

control

5.The main idea of the passage is ________.

Athat respecting each other is more important than anything else

Bhow kids behave to ignore and disrespect their parents

Cthat children should make choices and decisions on their own

Dhow parents can deal with their kids’ behavior effectively

How would you like to teach yourself, rather than have teachers? According to the UK’s Department of Education and Skills, students will teach themselves in the schools of the future. This means that there will be no more problems such as finding enough teachers.

Estelle Morris, the UK Education Secretary, opened the 2002 Education Technology Conference in London recently. To start the conference, she presented a video showing a computer—generated model of the school of tomorrow.

Greater use of computer technology and classroom assistants will help students develop their own way of learning, Morris said. She added that this is a more exciting as well as a more interesting way of learning.

At the same time, teachers will be “freed from their traditional role as the source of all knowledge”.

Children of all abilities will “form the curriculum(課程)around their individual needs.” They will “l(fā)earn in their own time, at their own speed and in their own environment”.

At home or at school, they will follow their learning programmes by looking at online libraries and watching lessons by world-class teachers and subject experts.

Instead of going on field trips, students will use virtual reality. If they don’t understand something, they can ask other students—“take part in virtual communities with learners with similar needs”—or e-mail their teachers. They will hand in their work electronically to be “auto-marked”.

The classroom of the future is fast becoming a reality.

And the Department of Education will soon produce a guide to help schools adapt buildings for new technology, Morris said. These ideas are based on the UK government’s plan to create an education system that provides students with a strong grounding of knowledge and skills at primary school level. And provides the chance for students to develop their individual skills at secondary school level.

1.According to the UK’s Department of Education and Skills, the school of the future will ______.

A. cause more problems such as being able to find enough teachers

B. set no homework and no tests for students

C. make good use of the computer technology and classroom assistants

D. enable students to learn by themselves without teachers

2.Estelle Morris thinks that computer technology does good to teachers in ________.

A. helping students develop their own way of learning

B. enabling students to experience interesting and exciting ways of learning

C. providing students with knowledge of all sorts

D. not being considered the source of various knowledge

3. If the students do not understand something, they can _______.

A. go on a field trip

B. go to ask their teachers to help them

C. send e-mail to ask for a teacher’s help

D. have a look at other learners’ homework

4. If s a student is under the UK’s newly-developed education system,he will be ________.

A. provided with a basic knowledge from the beginning

B. given more knowledge at primary school level

C. helped to use computers better

D. supplied chance to develop their basic skills
