Anyone who has ever traveled with a teenager ...

Anyone who has ever traveled with a teenager knows that the teenager can make the vacation good or bad for the entire family. As a travel agent, Lynda Maxwell said, “If teenagers are happy, everybody is happy.”

Teenagers are often interested in travelling, but their interests and schedules often aren’t the same as their parents’. It means that when the parents start to look for a place of interest in the early morning, their teenagers may be sleeping soundly!

The thing makes travelling with teenagers very difficult, but it isn’t impossible. The experts said, “The keys to success is what parents do before they travel.”

For many families, the hardest part may be finding a vacation time that is right for everyone. Be sure to sit down with everyone else in the family before setting a date.

“After setting a date, ask teenagers where they would choose to go,” suggested Maxwell. It is possible that they’d like nothing more than to sit on a beach for a week. “Maybe there’s a compromise(折中),” said Maxwell.

“Most teenagers like using the Internet now, so parents can ask them to think up the ideas about what to see and do,” said Brad Anderson. “I find teenagers are excellent at making great suggestions.”

1.The main problem of travelling with teenagers is that______.

A. they are always causing problems

B. there’s no way to make them happy

C. they don’t want to travel with their parents

D. their interests and schedules are different from their parents’

2.Maxwell thinks that________.

A. teenagers are good at making suggestions

B. parents should discuss the travel plan with their teenagers

Anyone who has had a long-term illness knows that recovering at home can be boring. This can be especially true for children. They may feel cut off from their friends and classmates. Now, these children may have a high-tech friend to help feel less lonely. That friend is a robot.

The robot is called Avatarl(AV1). It takes their place at school. Through the robot, the children can hear their teachers and friends. They can also take part in classes from wherever they are recovering. And the children’s school friends must help. They carry the robot between classes and place the robot in the classroom.

A Norwegian(挪威的) company called “No Isolation” created the robot. There are another two co-founders, Karen Dolva and Marious Aabel. Dolva explains how the robot works. She says from home the child uses an iPad or a phone to start it, control the robot’s movements with touch and talk through it. The child can take part in classroom activities. The robot is equipped with speakers, microphones and cameras that make communication easy. So it’s the eyes , the ears and the voice of the child at school. Inside AV1 there is a small computer connected to a 4G network.

AV1 is designed to be tough. It won’t allow water to pass through it and can take a fall from a desk without damage. AV1 is large and looks like a human for a reason. Dolva says it can’t be just a tiny camera because the other kids can’t pick it up and take it with them. This is important because the robot is supposed to be a friend to the children. Hopefully AV1 will help some children feel less lonely while they were absent from class.

Dolva, one co-funder （创始人）of No Isolation.explains how the robot AV1 works. She says, “the robot sits at the child's desk in the classroom and the child at home uses a tablet（平板电脑）or a phone to start it, control its movement with touch, and talk through it. So the robot becomes the eyes, the ears and the voice of the child at school.” The robot is equipped with speakers, microphones and cameras that make communicating easy. Moreover，The AVI was designed to be tough. It is water-resistant(防水) and can take a fall from a desk without damage. Inside AV1 is a small computer connected to a 4G network. AV1 is large and looks like a human for a reason. Dolva thinks this is important because the robot is expected to be a friend to the children.

The Teenage Brain

Parents, teachers, and others who deal closely with teenagers know how difficult the adolescent(青少年的) years can be. This was thought to be due to the “foolishness of youth.” Now, brain-imaging technology allows scientists to study the physical development of the brain in more details than ever before. Their discoveries have led a new theory of why teens act this way.

Recently, scientists have discovered that though our brains are almost at their full size by the age of six, they are far from fully developed. Only during adolescence do our brains truly “grow up.” During this time, they go through great changes, like a computer system being upgraded. This “upgrade” was once thought to be finished by about age 12. Now scientists have found that our brains continue to change until age 25. Such changes make us better at balancing impulses (冲动) with following rules. But a still-developing brain does this clumsily (笨拙地). The result, scientists believe, is the unpredictable behavior seen in teenagers.

The studies show that teens are more likely to take risks. Luckily, the news isn’t all bad. As brain scientist B. J. Casey points out, the teen brain inspires such behavior in order to help teens prepare for adult life.

One way the brain does this is by changing the way teens measure risk and reward (回报).

Researchers have found that when teens think about rewards, their brains release more of the chemicals that create pleasure. Researchers believe this makes the rewards seem more important than the risks, and makes teens feel the excitement of new experience.

Research into the structure of the teen brain have also found that it makes social connection seem especially rewarding. As such, teens have a strong need to meet new people. Because it is still developing, a teen brain can change to deal with new situations. So it connects social rewards with even more pleasure. In this way, the brain encourages teens to have a wide circle of friends, which is believed to make them more successful in life.

Unluckily, this need for greater rewards can sometimes lead teens to make bad decisions. However, it also means that teens are more likely, and less afraid, to try new things or to be independent. And in the long run, the impulses of the teen brain are what help teens leave their parents’ care and live their own life successfully.

1.According to Paragraph 2, what have the scientists discovered now?

A.A changing brain helps follow the rules.

B.Our brains finish upgrading by age of twelve.

C.Our brains are fully developed by the age of six.

D.A developing brain can cause unpredictable behaviors.

2.The writer probably agrees that　　　　　　 .

A.teenagers should learn from their bad decisions

B.many teenagers are able to change their behaviors

C.the way the teen brain works makes them less afraid

D.the impulses of a teenage brain should be controlled

3.What can we learn from the passage?

A.The teen brain makes risks less exciting.

B.The impulse of teen brain can benefit teenagers.

C.Teenagers with more friends are more successful.

D.Teenagers make wrong decisions because of their brain.

Has anyone ever told you that eating carrots will help you see in the dark?

This is just one of many incorrect beliefs you may have heard. Below, we have picked out scientific explanations for three mistakes that people make about their eyes. Let's take a look.

Can eating carrots improve your eyesight?

Carrots are rich in vitamin A, which helps the eyes to turn light into information for your brain. This allows people to see in darker places.

However, eating more carrots won't help you see better. A certain minimum amount will help, but a large number of carrots will not give you superhuman vision.

If your parents have bad eyesight, will you have bad eyesight, too?

Myopia(近视)can be passed from parents to children.

A study by the American Optometric Association found that if both parents are myopic, there's a 33 to 60 percent chance that their child will be. For children who have one parent with myopia, the chance is 23 to 40 percent. and it's down to 6 to 15 percent for kids with non-myopic parents.

So if your eyesight is bad, your children might still have good vision.

Do color blind people see the world in black and white?

Color blindness doesn't usually mean that people see the world like an old movie. They usually can't tell certain colors apart, especially green and red. Another commonly confused pair of colors is yellow and blue.

Our eyes have cone cells (视锥细胞) that sense different wavelengths (波长) of light. If these cells don't work properly, color blindness occurs.

There are different levels of color blindness. Some people are only color blind in low light.

However, in the most serious form of color blindness, everything is shades of gray.

1.According to the article, eating carrots ________.

A.stops the brain from seeing

B.doesn't help you see better at all

C.will help you see clearly in the dark

D.is good for your eyes to some degree

2.If both parents have myopia, their child's chance of having good eyesight is ________.

A.40-67% B.33-60% C.23-40% D.6-15%

3.What is the cause of color blindness, according to the text?

A.Watching movies for too long.

B.Getting too little exercise.

C.Cone cells not working properly.

D.Changes in the wavelength of light.

4.Which statement is RIGHT?

A.You can have superhuman vision after eating a large number of carrots.

B.If your parents have bad eyesight. You might still have good vision.

C.Color blind people see the world in black and white.

D.It's unnecessary to protect our eyes.

5.What is the purpose of the article?

A.To offer some advice on protecting your eyes.

B.To clear up some misunderstandings about our eyes.

C.To provide help for improving your vision.

D.To explain how bad eyesight and color blindness form.

九年级英语单项填空中等难度题查看答案及解析

Do you know of anyone who uses the truth to deceive(欺骗)? When someone tells you something that is true, but leaves out important information that should be included, he can give you a false picture．

For example, someone might say, “I just won a hundred dollars on the lottery(彩票). It was great. I took that dollar ticket back to the store and turned it in for one hundred dollars!”

This guy is a winner, right? Maybe, maybe not. We then discover that he bought $ 200 worth of tickets, and only one was a winner. He’s really a big loser!

He didn’t say anything that was false, but he left out important information on purpose. That’s called a half-truth. Half truths are not technically lies, but they are just as dishonest.

Some officers often use this trick. Let’s say that during Governor Smith’s last term, her state lost one million jobs and gained three million jobs. Then she tries another term. One of the persons who don’t support her says, “During Governor Smith’s term, the state lost one million jobs!” That’s true. However, an honest statement would have been, “During Governor Smith’s term, the state had a net gain of two million jobs.’’

Advertisers will sometimes use half—truths. It’s against the law to make false statements so they try to mislead you with the truth. An advertisement might say, “Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache. ”It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company.

This kind of thing happens too often. It’s a sad fact of life: Lies are lies, and sometimes the truth can lie as well.

1.We may infer that the author believes people should ________.

A. buy lottery tickets if possible

B. make use of half—truths

C. be careful about what they are told

D. not trust the Yucky Company

2.How many examples does the writer give to show how the truth is used to deceive?

A. One　　 B. Two　　 C. Three　　 D. Four

3.Which of the following is true according to the passage?

A. Using half truths is against the law.

B. Technically, half truths are in fact lies.

C. Yucky Pills is a very good medicine for toothache.

D. Governor Smith did a good job during her last term.

4.Which of the following best expresses the main idea of the passage?

A. He’s really a big loser!

B. Sometimes the truth can lie．

C. Advertisers will sometimes use half truths．

D. It’s against the law to make false statements．
