The third-generation hybrid rice（杂交水稻）which was developed by Yuan Longping, the "father of hybrid rice", and his team ran its first public yield（产量）monitoring from Monday to Tuesday and achieved high output. The final yield of the tested variety, G3-1S/P19, came to1046.3 kg per mu（about 667 square meters）, based on two pieces of land in Qingzhu Village under the city of Hengyang in central China's Hunan Province.
"Some previous high-yielding hybrid rice varieties in China took 160 to even 180 days from sowing（播种）to harvesting, while the figure was shortened to around 125 days for the new variety. This is one of the most important features（特征）of the third-generation hybrid rice that can reduce the use of pesticides（杀虫剂）and fertilizers（化肥）, thus reducing cost and improving production efficiency." said Qian Qian, the deputy director of the China National Rice Research Institute.
Unlike the previous two generations that required a large amount of water and fertilizers as well as demanding growing conditions and technological support, the third-generation hybrid rice is easier to be cultivated（种植）by ordinary farmers. So the soil, altitude and climate of the test site were not "ideal conditions" carefully selected beforehand but were close to the paddies（稻田）of ordinary farmers.
Nowadays. China's average yield of rice is about 500 kg per mu. Ordinary farmers can produce 600 kg to 700 kg of rice per mu by growing some excellent second-generation hybrid rice varieties. However, under the same planting conditions and environment, the yield of the third-generation hybrid rice could reach 800 kg per mu. China now feeds around 20 percent of the world's population with less than 9 percent of the world's arable（可耕种的）land.
At present, Yuan's team has nine third-generation hybrid rice combinations under trial, which are expected to achieve commercial seed production in the following three to four years and hope to apply the technology into the research of sea rice. The third-generation hybrid rice has the comprehensive strength to promote a greener and more sustainable development of China's rice production with higher quality and yield.

Any foreigner who has tried to learn Chinese can tell how hard it is to master the tones required to speak and understand. And anyone who has tried to learn to play the violin or other instruments can report similar challenges.
Now researchers have found that people with musical training have an easier time learning Chinese. Writing in the online edition of Nature Neuroscience，researchers from Northwestern University say that both skills draw on the same parts of the brain that help people discover changes in pitch(音调).
One of the study's authors，Nina Kraus，said the findings suggested that studying music “actually tunes our sensory system”.This means that schools that want children to do well in languages should hesitate before cutting music programs，Dr. Kraus said. She said music training might also help children with language problems.
Mandarin(普通话)speakers have been shown to have a more complex encoding(编码) of pitch patterns in their brains than English speakers do. This is because in Mandarin and other Asian languages，pitch plays a central role. A singlesyllable word can have several meanings depending on how it is intoned.
For this study，the researchers looked at 20 nonChinese speaking volunteers，half with no musical background and half who have studied an instrument for at least six years.
As they were shown a movie，the volunteers also heard an audio tape of the Mandarin word “mi” in three of its meanings:squint，bewilder and rice. The researchers recorded activities in their brain stems to see how well they were processing the sounds. Those with a music background showed much more brain activities in response to the Chinese sounds.
The lead author of the study，Patrick C.M.Wong，said it might work both ways. It appears that native speakers of tonal languages may do better at learning instruments.
1.When learning Chinese，a foreigner will find ________.
A.he has a difficult time learning music at the same time
B.he has an easier time learning music at the same time
C.it is hard to master the tones required to speak and understand
D.it is easy to use the brain to help him discover changes in pitch
2.Why does Chinese learning have something to do with music training?
A.Because there is the same difficulty in learning Chinese and music.
B.Because skills to learn the two make use of the same parts of the brain.
C.Because music training might help people with language study.
D.Because people who do well in Chinese study do well in music.
3.The underlined word “intoned” in the fourth paragraph can be replaced by the word “____”.
A.created B.spelled C.seemed D.pronounced
4.What would be the best title for this passage?
A.Mandarin Speakers Are Smarter than English Speakers
B.Skilled Ear for Music May Help Language Study
C.Pitch Plays a Central Role in Chinese Learning
D.Schools Need to Develop Music Programs
I cried the first time I saw the Notre Dame（巴黎圣母院）years ago. I'd waited my entire life to see this great French architecture, and experienced it in its full glory on a bright sunny day. Last night, I again cried for the centuries-old church while watching it burn.
I hadn't expected to spend my evening that way. My friend and I were having dinner at a cafe a block or so away from the Notre Dame, choosing to skip going inside with the intention to go back the next day.
However, we heard that it caught fire, so we left the cafe and ran towards the church, following heavy smoke from it, and soon we joined a nearly silent crowd. Some were praying, some were crying, but most were staring in disbelief at the disaster happening before us. The fire continued to get worse. About 400 firefighters were working to control the fire. We could see their flashlights shining as they inspected the front from a balcony.
The Notre Dame is part of the heartbeat of Paris, I reflected on the experiences I've had there, from attending a bread market out front to admiring the beautiful windows and architecture inside. It is a spot that helps make Paris magical. And here we were, watching it burn down. It was too much to handle, but it was impossible to look away.
About 9：30 pm, the gathered crowd spontaneously（自发地）began to sing Hymns（圣歌）to the church. We sang along with the group, feeling at once less like tourists and more like members of them. I hadn't imagined all that before.
For hundreds of years, the Notre Dame has seen the most joyous and the most terrible moments in the lives of both France and her people. And when everyone was able to become one emotional force, it showed that even in her darkest hour, the Notre Dame was still there to bring us all together.
1.Why did the author cry for the Notre Dame for the first time?
A.She was touched by its greatness. B.She was sorrowful to watch it burn.
C.She was regretful for missing its glory. D.She was excited about French cultures.
2.What was the author doing when the Notre Dame caught fire?
A.Heading for a faraway cafe. B.Visiting a church with a friend.
C.Eating nearby with a friend. D.Wandering along the street alone.
3.What can we know about the fire scene?
A.People expressed their sadness in different ways.
B.People were nervously rushing in different directions.
C.Hundreds of volunteers joined in putting out the fire.
D.Firefighters kept people away with shining flashlights.
4.What impressed the author most?
A.The church allowed visitors to gain great experiences.
B.Many foreign tourists became members of the church.
C.The church survived disasters for hundreds of years.
D.People were brought together to sing to the church.

Last Friday I took the subway home as usually. Since our physics teacher had just teach us in class that the escalator（自动扶梯） worked, I decided to see how fast the escalator went. To my surprise, it went a speed of about 40 m/min. The next day, I went to a department store with her cousin Emily. I times the escalator here too. I found that it was much slower, going about 30 meter every minute. Why? I check on the Internet and found the reason. Stores slow down escalators on a purpose, allowing customers more time to looking at their products.
