【题目】 How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.

The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.

The toothbrush will be able to teach you to brush right (dont forget the insides of the teeth!) and make sure youre brushing long enough. Its kind of like having a dentist actually watch your brushing on a day-to-day basis, says Thomas Serval, the French inventor.

The toothbrush will also be able to talk to other applications on your phone, so developers could, for instance, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. We try to make it smart but also fun, Several says.

Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said yes, but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.

The company says the Kolibree will go on sale this summer, for $99 to $199, developing on features. The U.S. is the first target market.

Serval says that one day, itll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.

【1】Which is one of the feature of the Kolibree toothbrush?

A. It can sense how users brush their teeth.

B. It can track users school performance.

C. It can detect users fear of seeing a dentist.

D. It can help users find their phones.

【2】 What can we learn from Servals words in Paragraph 3?

B. You should see your dentist on a day-to day basis.

C. You can brush with the Kolibree as if guided by a dentist.

D. Youd like a dentist to watch you brush your teeth every day.

【3】Which of the following might make the Kolibree toothbrush fun?

A. It can be used to update mobile phones.

B. It can be used to play mobile phone games

C. It can send messages to other users

D. It can talk to its developers.

【4】 What can we infer about Servals children?

A. They were unwilling to brush their teeth

B. They often failed to clean their toothbrushes.

C. They preferred to use a toothbrush with a dry head.

D. They liked brushing their teeth after Serval came home.

【5】 What can we learn about the future development of the Kolibree?

C. It will be used to fill holes in teeth

D. It will be able to check users teeth

【题目】Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy; there’s no need for a lot of scientific terms or expensive lab equipment. You only have to share your children’s curiosity(好奇).

Firstly, listen to their questions. I once visited a classroom of seven-year-olds to talk about science as a job. The children asked me “textbook questions” about teaching, salary(薪水) and whether I liked my job. When I finished answering, we sat facing one another in silence. Finally I said, “Now that we’re finished with your lists, do you have questions of your own about science?” After a long pause, a boy raised his hand, “Have you ever seen a grasshopper(蚱蜢) eat? When I try eating leaves like that, I get a stomachache. Why?” This began a set of questions that lasted nearly two hours.

Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, adults often wait only one second or less for an answer, no time for a child to think. When adults increase their “wait time” to three seconds or more, children give more logical(符合逻辑的), complete and creative answers.

Thirdly, watch your language. Once you have a child involved in a science discussion, don’t jump in with “That’s right” or “Very good”. These words work well when you encourage their good behavior(行为). But in talking about science, quick praise can mean that discussion is over. Instead, keep things going by saying “That’s interesting” or “I’d never thought of it that way before”, or coming up with more questions or ideas.

Lastly, show and don’t tell. Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass(放大镜), and they’ll understand why you want them to wash before dinner. Rather than saying that water evaporates(蒸发), set a pot of water to boil and let them watch the water level drop.

【1】According to the passage, children are natural scientists, and to raise their interest, the most important thing for adults to do is _______.

A. to let them see the world around

B. to share the children’s curiosity

C. to explain difficult phrases about science

D. to supply the children with lab equipment

【2】In the second paragraph, “your lists” could best be replaced by ______.

A. any questions

B. any problems

C. questions from textbooks

D. any number of questions

【3】 According to the passage, children can answer questions in a more logical, complete and creative way if adults ________.

A. ask them to answer quickly

B. wait for one or two seconds after a question

C. tell them to answer the next day

D. wait at least for three seconds after a question

【4】In which paragraph does the author tell us what to say to encourage children in a science discussion?

A. The second B. The third

C. The fourth D. The fifth

【5】The author mentions all of the folowing techniques(技巧) for adults to share with their children’s curiosity except that adults should ________.

A. tell their children stories instead of reciting (背诵) facts

B. offer their children chances to see things for themselves

C. be patient enough when their children answer questions

D. encourage their children to ask questions of their own

【题目】阅读理解

第一节 阅读短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?

UBC Professor Simard explains how trees are much more complex than most of us ever imagined. Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their co-operation and support, passing around necessary nutrition “depending on who needs it”.

Nitrogen (氮) and carbon are shared through miles of underground fungi (真菌) networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons (神经元) in our brains, and when one tree is destroyed, it affects all.

Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the entire forest.

We didn’t take any notice of it.” Simard says sadly. “Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

【1】 Why does the author say “the opposite is true”?

A. Because trees compete for survival.

B. Because trees depend on each other.

C. Because trees provide support for dying trees.

D. Because trees protect their own wealth.

【2】Mother trees are extremely important because they ________.

A. look the largest in size in the forest

B. know more about the complex “tree societies”

C. pass on nutrition to young trees

D. seem more likely to be cut down by humans

【3】 What does the underlined word it in the last paragraph refers to?

A. How “tree societies” work.

B. How trees grow old.

C. How forestry industry develops.

D. How young trees survive.

【4】 What would be the best title for the passage?

A. Old Trees Communicate Like Humans

B. Young Trees Are in Need of Protection

C. Trees Contribute to Our Society

D. Trees Are More Amazing Than You Think
