Dolores Huerta has worked hard most of her life to help other people. She has helped change things so that farm workers can have a better life.
Dolores grew up in California. She was a good student and liked school. After she finished high school, she went to college and studied to be a teacher. After she became a teacher, Dolores noticed that many of her students were not getting enough food to eat. Some of them wore very old clothes. Dolores wondered how she could help them.
Dolores decided to stop teaching so that she could spend more time helping the farm workers and their families. One thing she wanted to do was to get more pay for farm workers so they could buy their children the things they needed.
Dolores knew that many farm workers moved often from one place to another to help pick different kinds of fruits and vegetables. She began talking and writing about these workers. Even people who lived far from California read what Dolores wrote.
Getting higher pay for the farm workers was not easy. Dolores worked hard to make sure that farm workers got good pay for their work. She knew that nothing would change unless people made new laws to help the workers. Through all her hard work, new laws were made that gave farm workers good pay.

On my recent trip to Sydney with my parents，we visited the Wildlife Park．
The Wildlife Park has lots of different animals and birds．Some are native （当地的） to Australia and can only be found there．There are over 600 animals there，including kangaroos，koalas and crocodiles （鳄鱼）．They are kept in their natural environment．I like the Wildlife Park better than a zoo where most of the animals are in cages （笼子）．
We first spent some time with the kangaroos．We were allowed to touch and feed them．It was very exciting to be so close to them．There were koalas there too．They looked very cuddly （令人想拥抱的）．Although we were not allowed to carry them，I got to take a photo with one．

"I am so busy with my study． I don't even have enough time to have breakfast．"said Zhangli， a middle school student． Do you have the same problem __A__ Zhangli？ However， missing breakfast could raise your risk of heart problem by 87 percent， according to a new study． Researchers at the University of Iowa analyzed 18 years of data on 6，550 people over 40 years old who had no history of heart problems．They were given regular surveys __B__ included the question， "how often do you eat breakfast？ Most （59 percent）ate breakfast every day，but 5.1 percent never did，10.9 percent rarely did， and 25 percent would miss for a few days． The team found that①早餐习惯与心脏病风险之间存在明显关联．Those who didn't eat in the morning were up to 87 percent more likely to develop heart problems．
" It's believed that ②an， important， day， breakfast， the， is， meal， of， but there has been an
increasing prevalence （普遍）of missing breakfast over the past 50 years in the United States， with as many as 23.8 percent of young people missing break fast every day，" the researchers said．"However， studies on the health effects of missing breakfast are rare．"
The team pointed out a few factors which could underlie this connection． ③ Firstly ， those who don't eat breakfast may be more likely to snack unhealthily ．Secondly， breakfast may help to balance blood sugar levels and control blood pressure． The findings were published on the American College of Cardiology． Some days later a similar study showed people who missed breakfast and ate a late dinner were less likely to survive a heart attack． And Borja Ibanez， a doctor of medicine， also pointed out those who didn't eat breakfast were more likely to smoke， be lack of exercise， and drink alcohol．

Many environmental groups are warning that oceans of the world are in great danger． In the past 50 years，the number of water with zero oxygen（氧气） in the open ocean has increased more than four times． In the near coast water bodies， including the river mouth and seas， low﹣oxygen areas have increased more than 10 times since 1950．Scientists discover that oxygen continues dropping ever outside these zones as the Earth warms． To stop the drop，the world needs to control in both climate change and nutrient（养分） pollution．
Oxygen is a must to life in the oceans． The drop in ocean oxygen is among the most serious effects of human activities on the Earth's environment．
This is the first time for the scientists to take such a deep look at the causes， results and solutions to low oxygen worldwide， in both the open ocean and the near coast waters．About half of the oxygen on Earth comes from the ocean． However， mixed effects of nutrient loading and climate change are greatly increasing the number and size of "dead zones" in the open ocean and the near coast waters， where oxygen is too low to support most sea life．
In the areas traditionally called"dead zones"． like those in Chesapeake Bay and the Gulf of Mexico， oxygen drops to levels so low that many animals have trouble in breathing and die．As fishes run away from these zones， their living areas become smaller and smaller． But the problem goes far beyond "dead zones"． Even smaller oxygen drops can hold up the growth in animals and lead to disease or even death． Low oxygen also can cause the release of dangerous chemicals．Although a few animals can grow well in dead zones， overall biodiversity（多样性）falls．

（2）Why are these waters called"dead zones" from the article？
| A． |
Because the oxygen in these areas is too low for most sea life to live． |
| B． |
Because nutrient loading and climate change are greatly increasing． |
| C． |
Because there are no animals living in these areas． |
| D． |
Because low oxygen also can cause the release of dangerous chemicals． |

Thanks to the hybrid rice that was discovered by Yuan Longping， the hunger problem of thousands of Chinese people was mostly fixed in the 1980s．
On Sept 8 th，Yuan， together with two other scientists，won China's 2018 Future Science Prize， for his continuous research on rice． Even on his 88th birthday on Sept 7 th，he took part in the International Development Forum of Rice Production in Hunan province． Although he was recovering from an illness at the time， he was happy to talk to reporters about his latest work on seawater rice．
Yuan has been researching on rice since he was at college． In 1964． he discovered a natural hybrid rice plant in Hainan． Since then， he has focused on developing high﹣yield， hybrid rice varieties
（多样性）．In 1973． he became the first to successfully cultivate（培育） a type of hybrid rice species in
the world．With the hard work of Yuan's group for about ten years， the production of the rice was increased．（From 150 kg per mu （亩） to 500 kg per mu and more． ）These varieties now take up about two thirds of China's rice crop， according to China News． So， it's no wonder that he's known as the "Father of Hybrid Rice"．
And because of China's Belt and Road （一带一路）initiative． Yuan's hybrid rice is helping to solve food problems around the world． Indeed， according to Xinhua News Agency， hybrid rice plants in Kenya produce four to five times more rice than the country's usual nice plants．
With a rising fame all over the world， Yuan gave a speech in English at the 9th Shandong High﹣Level Talents Forum in Qingdao last year． His speech made him an internet sensation．Beginning with"I speak broken English"， his 20﹣minute speech turned out to be a huge success，with barely any pauses or mistakes． The humble Yuan was simply being modest during his speech．According to an article in 1999 by CNN， the scientist speaks both English and Russian fluently． "I never need an interpreter when I go overseas，" he told the US news network．
But in spite of his great knowledge， Yuan understands that even the wisest people should still be open to learn new things． "The farmers of our country possess rich experience in planting rice，"he told Xinhua．" We should learn from them．"
