A research found that people shown silent videos of piano competitions could pick out the winners more often than those who could also hear the music. It underlines the importance of our sense of vision, say scientists. Their study concludes that the best predictor of a winner’s musical performance was the visible passion they displayed, followed closely by their uniqueness and creativity.

Chia-Jung Tsay, from University College London, UK, is the study’s author and herself a concert pianist. She was interested in how music was judged and found that even professional musicians were unaware of how much they were using visual information over sound. “For the last two decades, I’ve taken part in various competitions. Through this experience, I found that depending on what type of evaluations were used, the results might vary widely. This led me to wonder about how much visual information really affects these important decisions,” she explained.

More than 1,000 participants in the study were given samples of either audio, silent video or video with sound, and asked to rate the top three finalists from 10 international classical music competitions. The actual competition winners were only correctly identified by those who were randomly assigned(分配) the silent videos.

Dr Tasy said the findings were quite surprising, especially because both trained musicians and those without training had stated that sound was most important for their evaluation. “Regardless of levels of expertise, we still seem to be led primarily by visual information, even in this field of music,” she said. “Classical music training is often focused on improving the quality of the sound, but this research is about getting to the bottom of what is really being evaluated at the highest levels of competitive performance. She added, “We must be more mindful of our inclination(倾向) to depend on visual information at the expense of the content that we actually value as more relevant to our decisions.”

Money, jewels and important documents are not the only valuable placed in banks these days. Some mothers store their breast milk in banks.

There’re ten breast banks set up across the United States, where mothers can donate their extra milk for other women’s babies. Experts say breast milk is the best food for babies. The World Health Organization says it is the only food babies should get during the first six months of life, in most cases. Breast milk is especially important for babies born too early. Sometimes these premature babies must stay in the hospital for many weeks.

James Cameron is a doctor who treats newborns at Lutheran Children’s Hospital in Fort Wayne, Indiana. He says breast milk is almost like medicine. Doctor James Cameron said, “The fact is that there are so many different proteins and specialized sugars in the breast milk that the mom’s able to make that help provide immunity. It’s very important for the health of the newborn.”

There are several reasons some mothers may not be able to breastfeed. Some are not able to produce enough milk. Others might be taking medicines or have medical problems that prevent the process.

Lucy Baur lives near Fort Wayne. She fed her milk to both her children and always had more milk than they needed. She wanted to donate to the Indiana Mothers Milk Bank in Indianapolis. But freezing and shipping milk can be costly. Then, a donor station opened near her home.

Milk donations in the United States work like this: Donors must be willing to provide almost three liters of breast milk. They freeze the milk and take it to the station. There, employees warm the milk and mix it with other mothers’ milk. Then, the milk is heated to kill bacteria. After that, the technicians test samples of all the milk to make sure it is safe and healthful. The milk is re-frozen and sent to the main milk bank. The milk bank transports the milk to hospitals to feed premature or sick babies. Donors are tested for diseases before any milk is accepted. They are not permitted to smoke tobacco, use illegal drugs or drink too much alcohol.

1.The purpose of setting up breast milk banks is to_____.

A. store extra fresh milk for school children

B. provide milk to children who go hungry

C. help mothers donate milk to other babies

D. offer free breast milk to premature babies

2.The breast milk is important for newborns because_____.

A. it protects them from any possible disease

B. it contains rich nutrients that they need

C. it is the only food that babies can eat

D. it benefits them as the best medicine

3.The underlined word “they” in the last paragraph refers to____.

A. milk bank employees B. milk bank doctors

C. milk bank nurses D. breast milk donors

4.Which of the following shows the process of milk donations in the USA?

a. The mixed breast milk is heated to kill bacteria.

b. Breast milk is donated by mothers, frozen by them and sent to the stations.

c. The breast milk samples are tested for safety reason.

d. Different donors’ breast milk is warmed and mixed together by the station.

e. The milk is frozen again and sent to the main milk bank.

A. bdace B. bcdea C. badec D. cbaed

Many schools require yearly parent teacher conferences for all students. ___1.__.The list below is to help teachers prepare themselves for these often difficult conferences.

___2.__.When you have students who are struggling in either their academics or their behavior, you should communicate with their parents using notes or phone calls.

Come to the conference well-prepared. If the student is having a hard time with their work, show the parents their grades and samples of their work. ___3.___ .If the student is misbehaving, then you should make detailed notes of their behavior before the conference. Bring these notes to the conference so that parents can understand how their children are behaving.

____4.__. For example, you might say something about their creativity, their handwriting, their sense of humor, or make some other comment. Instead of restating the problems you’ve already discussed, end with a comment that offers hope for the future. You could say something like, “ Thanks for meeting with me today. I know that working together we can help Johnny succeed.”

Some teachers may have to deal with an angry parent at some point. ___5.__. Much anger can be avoided if the parents are informed. Don’t get excited yourself and make sure you avoid shouting.

Communicating with parents before a conference is necessary.

Try to think of something nice to say about the students that have problems.

At the end of the conference, you should make a conclusion.

A parent teacher conference can have a huge impact on a student’s work and behavior.

Remember to thank the parents for coming to the conference and working with you.

Remember that the best way to solve this is to keep parents informed every step of the way.

G. It is easier for parents to understand the problem if they can actually see examples of their children’s work.

Plants can’t communicate by moving or making sounds, as most animals do. Instead, plants Produce volatile compounds, chemicals that easily change from a liquid to a gas. A flower’s sweet smell, for example, comes from volatile compounds that the plant produces to attract insects such as Bugs and bees.

Plants can also detect volatile compounds produced by other plants. A tree under attack by Hungry insets, for instance, may give off volatile compounds that let other trees know about the Attack. In response, the other trees may send off chemicals to keep the bugs away ——or even Chemicals that attract the bugs’ natural enemies.

Now scientists have created a quick way to understand what plants are saying: a chemical Sensor（传感器）called an electronic nose. The “e-nose” can tell compounds that crop plants make When they’re attacked Scientists say the e-nose could help quickly detect whether plants are being Eaten by insects. But today the only way to detect such insects is to visually inspect individual Plants. This is a challenging task for managers of greenhouses, enclosed gardens than can house Thousands of plants.

The research team worked with an e-nose than recognizes volatile compounds. Inside the device, 13 sensors chemically react with volatile compounds Based on these interactions, the e-nose gives off electronic signals that the scientists analyze using computer software.

To test the nose, the team presented it with healthy leaves from cucumber, pepper and tomato plants, all common greenhouse crops. Then scientists collected samples of air around damaged leaves from each type of crop, These plants had been damaged by insects, or by scientists who made holes in the leaves with a hole punch（打孔器）. The e-nose, it turns out, could identify healthy cucumber, pepper and tomato plants based on The volatile compounds they produce, It could also identify tomato leaves that had been damaged. But even more impressive, the device could tell which type of damage ---- by insects or with a hole Punch ---- had been done to the tomato leaves.

With some fine-tuning, a device like the e-nose could one day be used in greenhouses to quickly spot harmful bugs, the researchers say. A device like this could also be used to identify fruits that are perfectly ripe and ready to pick and eat, says Natalia Dudareva, a biochemist at Purdue University in West Lafayette, Ind. who studies smells of flowers and plants. Hopefully, scientists believe, the device could bring large benefits to greenhouse managers in the near future.

1.We learn from the text that plants communicate with each other by____.

3.According to the writer, the most amazing thing about the e-nose is that it can___.

A. pick out ripe fruits

B. spot the insects quickly

C. distinguish different damages to the leaves

D. recognize unhealthy tomato leaves

4.We can infer from the last paragraph that the e-nose_____.

A. is unable to tell the smell of flowers

B. is not yet used in greenhouses

C. is designed by scientists at Purdue

D. is helpful in killing harmful insects
