【題目】Life gets noisier every day and very few people can be free from noise of some sort or another. It doesn’t matter where you live ---- in the middle of a modern city, or a faraway village --- the chances are that you’ll be disturbed by jet planes, transistor radios, oil-powered engines, etc. we seem to be getting used to noise, too. Some people feel quite lonely without background music while they’re working.

Scientific tests have shown that total silence can be a very frightening experience for a human being. However, some people enjoy listening to pop music which is very loud, and this can do harm to their eardrums (耳鼓). The noise level in some discos is far above the usual safety level for heavy industrial areas.

One recent report about noise and concentration suggested that although a lot of people say that any noise disturbs their concentration, what really influences their ability to concentrate is a change in the level of noise. It goes on to say that a background noise which doesn’t change too much (music, for example) may even help to concentrate.

【1】According to this passage, the noise pollution ____________________.

A. has become the worst in the countryside

B. has become better in big cities

C. has spread from cities to villages

D. has been controlled in modern cities

【2】Some people have their hearing harmed _____________.

A. while listening to pop music

B. in complete silence

C. when speaking loudly

D. while watching TV

【3】Which of the following isn’t included among the things causing noise?

A. trucks B. motorcycles

C. electric engines D. jet planes

【4】Scientists have discovered that what prevents people from concentrating on something is _______.

A. all kinds of noise B. great changes in the level of noise

C. background noise D. popular music

【題目】The human body is designed to move. But modern lifestyles and office jobs rarely give us the chance to move around. As we know. we're while we're eating; we sit in the car and we sit while we watch TV. And many of us sit for many hours at work.

New research shows that sitting less than three hours a day might extend your life by two years. Peter Katzmarzyk，a scientist at the University of Louisiana in the southern United States，says that sitting is ubiquitous in our lives，meaning it is something we do all the time，everywhere.

However，Mr. Katzmarzyk says that does not mean you can sit for the rest of your waking hours. He also says you may exercise often，“We can't throw away physical activity. It's extremely important. We have 60 years of research showing us that. ”

Mr. Katzmarzyk and his coi leagues are part of a new generation of researchers studying how sitting all day affects length of life. “Studies that have assessed the relationship between sitting and mortality(死亡率)or television viewing and mortality are very rare. There's only been a few of them，actually five or six now，in the last four or five years. ”They found that cutting television time to less than two hours a day could add one-point four years to life.

Luckily，change is already coming to some offices，especially in the design of desks. A “standing desk”lets people stand while they work. Another new design is called the “treadmill desk. ” A treadmill is an exercise machine that lets you walk in one place Even some U. S. schools are beginning to experiment with desks that are part bicycle to keep children moving. That's one of the strategies that many companies are using now.

Mr. Katzmarzyk also says studying this problem has inspired his team to make a few changes in their own lives.

【1】Which view agrees with the opinion of Mr. Katzmarzyk?

A． Sitting too long may help increase one's life.

B． Exercise is important and don't sit too long.

C． Watching TV is bad，but can broaden one's horizons.

D． Stopping watching TV is a necessary but hard task.

【2】What does Mr. Katzmarzyk think of his study in Paragraph 4?

A． It's a ly new area of study.

B． It's a hot subject studied by experts.

C． It's a study that begins too late.

D． It's not ignored by many experts.

【3】Why are the desks of all kinds designed for those who sit more?

A． To give them more comfort.

B． To improve their work efficiency.

C． To offer them the chance to exercise.

D． To seek pleasure while working.

【題目】閱讀下列短文，從每題所給的四個選項（A、B、C和D）中，選出最佳選項。

When you’re a parent to a young child, you spend a lot of time talking about feelings: about having to share, about being disappointed because you may not have a cookie instead of broccoli(綠花椰菜), about the great injustice of a parent pressing the elevator button before the child has a chance to.

And in a parenting culture that’s increasingly concerned with centering children’s needs above all else, mothers and fathers have become skillful at talking about their kids’ feelings while masking their own. But new research suggests that parents who hide their negative emotions are doing their children, and themselves harm.

A study published this month says that when parents put on a faux-happy (假開心)face for their kids, they do damage to their own sense of wellbeing and authenticity.

“For the average parent the findings suggest when they attempt to hide their negative emotion expression and over express their positive emotions with their children, it actually comes at a cost: doing so may lead parents to feel worse themselves,” researcher Dr Emily Impett, says.

It makes sense that parents often fall back on amping up (擴大) the positivity for the sake of their children—there are a lot of things in the world we want to protect our kids from. But children are often smarter than we expect and are quite in tune with what the people closest to them—their parents—are feeling.

There was a time about a year or so ago, for example, when I received some bad news over the phone; I was home with my four-year-old and so I did my best to put on a brave face. She knew immediately something was wrong though, and was confused.

When I finally let a few tears out and explained that Mom heard something sad about a friend, she was, of course, just fine. My daughter patted my shoulder, gave me a hug, and went back to playing. She felt better that she was able to help me, and the moment made a lot more sense to her emotionally than a smiling mom holding back sobs. I was glad that I could feel sad momentarily and not have to work hard to hide that.

Relaying positive feelings to your children when you don’t feel them is a move the researchers called high cost—that it may seem like the most beneficial to your child at the time but that parents should find other ways of communicating emotions that “allow them to feel true to themselves”.

But this is also about children seeing the world in a more honest way. While we will want to protect our children from things that aren’t age-appropriate or harmful, it’s better to raise a generation of kids who understand that moms and dads are people too.

【1】 What is the typical behavior of parents when they bring up their children?

A. Allowing their children chances to do things themselves.

B. Expressing their dissatisfaction with their children.

C. Hiding their true emotions from their children.

D. Sharing their favorite food with their children.

【2】If parents put on a faux-happy face, _______.

A. their children will be protected

B. their children will be taken in

C. they will feel happy as a result

D. they will undergo worse feelings

【3】 The author mentioned the example of her daughter to illustrate ______.

A. children are not so clever as parents think

B. children can often understand parents’ true feelings

C. it’s meaningful for parents to always look positive

D. it’s necessary to expose children to harmful things

【4】We can conclude from the passage that _______.

A. protecting children from age-inappropriate things is important

B. it makes sense for children to know their parents’ negative feelings

C. children will admire their parents more because of being protected

D. separation from negative feelings helps children see the world honestly
