While music has value all by itself, researchers have long noticed that musicians also tend to be better at learning languages and show other improved reading and math abilities. Now a new study from the University of Washington by Christina Zhao shows that rhythm is an important bridge between music and speech as early as nine months of age.

Researchers randomly placed babies into two groups of 20 each, and each group played at the lab with their parents for a dozen 15-minute sessions over a month.

In one group, researchers played recordings of songs with a waltz rhythm and showed the parents how to help their babies tap out that 1-2-3 beat in time with the music on boy drums or with their feet. In the other group, children played with typical toys and no music.

The babies in the music group were better able to detect random mistakes in that rhythm when they heard it within two weeks of the last session. They also showed a stronger brain response to disruptions in the rhythm. For example, researchers would sometimes alter the timing of syllables(音节) by slightly shortening the middle sound of a word like bibbi to make it bibi—and the babies with music training were more likely to notice it.

In other words, music training not only improved the babies’ ability to notice when a musical rhythm skipped a beat, but also improved their ability to notice when the rhythms of speech changed unexpectedly, an important skill for learning to talk.

The study reflects Zhao’s personal experiences as a pianist who music in college, and as someone who speaks both Mandarin and English. She noticed that a lot of her fellow musicians were also good at learning other languages. “That really got me wondering how these two are related, “Zhao said.

Driving could soon be a far more pleasant experience thanks to a personal in-car robot being developed by researchers. The robot, which is called “Affective Intelligent Driving Agent (AIDA)” will be able to tell you the best route home based on traffic reports, remind you to pick up petrol and suggest places you may like to visit. The robot, which sits on the dashboard, is being developed at the Massachusetts Institute of Technology (MIT) in collaboration with Volkswagen.

AIDA communicates with the driver through an expressive robot screen and will even appear sympathetic if you're having a bad day. Cynthia Breazeal, director of MIT’s Personal Robots Group, said: “We are developing AIDA to read the driver’s mood from facial expression and other cues and respond in a proper way.”

AIDA works by analyzing the driver’s mobility patterns, keeping track of common routes and destinations. The creators say the robot should be able to work out home and work locations within a week of driving. Soon afterwards, the system will direct the driver to their preferred supermarket, suggesting a route that avoids traffic-clogged roads. AIDA might recommend a petrol stop en route if the fuel tank is nearly empty. The robot will also incorporate real-time information about traffic jams, the weather report, commercial activity, tourist attractions, and residential areas.

“In developing AIDA we asked ourselves how we could design a system that would offer the same kind of guidance as an informed and friendly companion.”

“AIDA can also give you feedback on your driving, helping you achieve more energy efficiency and safer behavior,” Assaf Biderman from SENSEable City Lab added.

1.What is AIDA in this passage?

A. A personal driver.

B. A traffic controller.

C. A traffic indicator.

D. A smart car robot.

2.What’s the most impressive about AIDA according to the passage?

3.From the last paragraph we can know that .

A. it’s possible to drive a car without any petrol

B. AIDA can help us to become better drivers

C. people can save a lot of energy by driving a car

D. It can help the driver find the way

4.What would be the best title for the passage?

Social change is more likely to occur in societies where there is a mixture of different kinds of people than in societies where people are similar in many ways. The simple reason for this is that there are more different ways of looking at things present in the first kind of society. There are more ideas, more disagreements in interest, and more groups and organizations with different beliefs. In addition, there is usually a greater worldly interest and greater tolerance in mixed societies. All these factors tend to promote social change by opening more areas of life to decision. In a society where people are quite similar in many ways, there are fewer occasions for people to see the need or the opportunity for change because everything seems to be the same. And although conditions may not be satisfactory, they are at least conventional and generally agreed.

Within a society, social change is also likely to occur more frequently and more readily in the material aspects of the culture than in the non-material, for example, in technology rather than in values; in what has been learned later in life rather than what was learned early; in the less basic and less emotional aspects of society-than in their opposites; in the simple elements rather than in the complex ones; in form rather than in substance; and in elements that are acceptable to the culture rather than in strange elements.

Furthermore, social change is easier if it is gradual. This is one reason why change has not come more quickly to Black Americans as compared to other American minorities, because of the sharp difference in appearance between them and white people.

1.Which of the following factors tends to promote social change?

A. Different points of view. B. Traditional values.

C. Advanced technology. D. Similar needs.

2.According to the passage, which of the following is NOT true?

A. Social change tends to meet with more difficulty in basic and emotional aspects of society.

B. Disagreement with and argument about conditions tend to slow down social change.

C. Social change is more likely to occur in the material aspect of society.

D. Social change is less likely to occur in what people learned when they were young.

3.What is this passage mainly discussing?

A. Two different kinds of society.

B. Certain factors affecting social change.

C. The importance of social change.

D. Consequences of social change

How to Care for Your Ears?

Ears not only let us hear, but they also play a role in maintaining our balance, which is vital to our ability to function in daily life. Yet, we ignore them. We can't even see our ears, except in a mirror. We take it for granted what they do for us day in and day out—until we notice something wrong, such as when an earache strikes or when we start having to ask people to repeat what they say.1.

◆Clean your ear with a washcloth—covered finger only.

Never put anything inside your ear canal, including cotton swabs(药签).2.

◆Leave earwax（耳垢）alone.

Wax is your ear's way of eliminating（消除）anything foreign that gets into the ear canal.3.If you find you have too much earwax, use a few drops of earwax remover in the canal. After a few minutes, wash the ear with warm water.

◆Avoid noisy places.

Rock concerts and construction sites are just a few places that frequently have noise levels that can damage hearing. Any place where you have to shout to be heard should be avoided.

◆4.

Be careful not to play MP3 too loud, especially if using earphone.

◆Be careful with illness and medications.

Respiratory（呼吸的）illnesses should be treated to avoid their spread to the ears. Certain medications can damage hearing, so follow the directions carefully before taking them.

See your doctor if you suffer from sudden hearing loss or hear noises in your head.5.

A. Turn the volume(音量) down.

B. Avoid using earphones while listening to MP3.

As we all know, it was Thomas Jefferson who wrote the Declaration of the Independence. He wrote it in two weeks, and after a few changes, it was accepted by the Congress. As a result, he became famous.

Born in Virginia, Thomas Jefferson, a brilliant student at school and almost talented lawyer later, was much interested in politics.

Jefferson was elected Governor of Virginia in 1779, and he was sent to France as the representative of the American government in 1784. Sixteen years later, at the age of 57, he was elected president after Washington and Adams.

Far from a handsome man, he was tall with long arms and big hands. Jefferson, who was an amusing talker in conversation but a poor speaker, was generally good-natured.

Jefferson was regarded as a defender of freedom on America. As a president, he protected the right of free speech. Interestingly enough, in his eight years as President, Jefferson never vetoed a bill which Congress had passed. He did a lot in organizing the new University of Virginia.

Thomas Jefferson died on July the fourth, 1826, the 50th anniversary of American Independence.
