Each morning at nine o’clock all the students, ranging in age from three to seven years old, gathered in the Great Room for a warm-up in preparation for the day.One morning the headmistress made an announcement to all the children gathered,“Today we begin a great experiment of the mind.” She held up two ivy(常春藤) plants, each potted in an identical container. She continued, “Do they look the same?”All the children nodded. So did I, for, in this way, I was alsoa child.“We will give the plants the same amount of light, the same amount of water, but not the same amount of attention,” She said. “Together we are going to see what will happen when we put one plant in the kitchen away from our attention and the other plant right here in this room. Each day for the next month, we shall sing to our plant in the Great Room and tell it how much we love it, and how beautiful it is. We will use our good minds to think good thoughts about it.”Four weeks later my eyes were as wide and disbelieving as the children’s. The kitchen plant was leggy and sick-looking, and it hadn’t grown at all. But the Great Room plant, which had been sung to and surrounded by positive thoughts and words, had increased threefold in size with dark leaves that were filled with energy.In order to prove the experiment, the kitchen ivy was brought to the Great Room to join the other ivy. Within three weeks, the second plant had caught up with the first ivy. Within four weeks, they could not be distinguished, one from the other.I took this lesson to heart and made it my own.1.

"As one of four children in a migrant（移民）farming family from Mexico, Jose - who didn't learn English until he was 12 years old - spent much of his childhood traveling with his family from Mexico to southern California each March, then working northward to the Stockton area by November, picking strawberries and cucumbers at farms along the route. They would then return to Mexico for Christmas and start the cycle all over again in the spring. "Some kids might think it would be fun to travel like that,“ Jose laughed, "but we had to work”.After graduating from high school, Jose was admitted into the University of the Pacific, In 1987, he accepted a full-time job with Lawrence National Laboratory. In 2001, Jose joinedtheJohnson Space Center, where he came face-to-face with Franklin Chang-Diaz.“We actually had common experiences —asimilar upbringing, the same language issues. That built up my confidence. Any barriers that existed, he had already overcome them.” Jose smiled. "Now it's my tum!,,“NASA rejected me not once, not twice, not three times but 11 times. It wasn't until the 12th time that I got selected, he said. Jose was selected as part of the 19th class of astronauts in 2004.

Learn from Your PastCThe World Wildlife Fund (WWF) says more than half of the world’s wildlife population has been lost, whichthe conservation group says has placed the health of the planet at risk.The WWF recently released its 10th Flagship Living Planet Report. The group warns the condition of the world's animals is worse than its earlier reports showed, indicating worldwide action is needed.The WWF is worried about the loss of and damage to Earth’s environment. The report provides information about more than 10,000 animal populations from 1970 to 2010. These populations are called “vertebrate species,” or animals with backbones — like fish, birds, mammals, amphibians and reptiles. The report shows these populations have dropped by 52 percent in just 40 years. It warns freshwater species have fallen by 76 percent, which is almost twice the loss of land and ocean species. Most of these losses are in the tropics, with the biggest drop inLatin America.Marco Lambertini, the WWF’s International Director-General said, “This is about losing natural habitats. This is aboutconvertingforests, grasslands, and wetlands into agriculture mainly, and it is about unsustainable use of wildlife. Illegal hunting has been actually increasing over the last 10 years, which definitely a driving force for extinction, particularly of large species.”The report also notes what it calls the world’s “Ecological Footprint”, that is, the effect of human activities on the planet. Mr. Lambertini says there has been an increase in carbon dioxide gases and the pouring of nitrogen into oceans and rivers from fertilizers used in agriculture, which certainly cannot continue.“We are consuming on average every year about the equivalent of about 1.5, one and a half times the resources available to the planet. That means we are cutting trees more quickly than they can be restored. We are fishing the oceans more quickly than fishing stocks can reproduce, and we are emitting in the atmosphere more CO2than the natural systems can actually absorb, which is clearly not sustainable.”Mr. Lambertini warns climate change affects almost everyone on the planet and that whole species may disappear if the world does not reduce the effects of humans on the climate.8. According to the passage, what kind of species faces the biggest drop in population?A. Land and ocean species.B. Animals with backbones.C. Freshwater species inLatin America.D. Freshwater species in the tropics.9. All the following can contribute to the loss of world’s wildlife population EXCEPT ________.A. turning wildlife habitats into agriculture land.B. making sustainable use of wildlife.C. hunting illegally.D. emitting CO2 gases and pouring nitrogen.10. Which does the underlined word “converting” in paragraph 4 mean?A. Conserving.B. Conveying.C. Exchanging.D. Transforming.11. It can be inferred from the passage that _______.A. Marco is much concerned about human’s current behaviors towards wildlife.B. what the planet provides now can satisfy human’s sustainable development.C. more than half of the world’s wildlife population has been lost.D. if humans reduce the effects on the climate, the whole species will not disappear.DIt’s a big change from homeless teen to Yale (耶鲁)medical school student, butperseverancepaid off for Chelesa Fearce of Clayton County, Georgia.Fearce was a fourth grader when her mom was diagnosed (诊断) with Lymphoma (淋巴瘤).That began a hard time for the family. They had to move in and out of shelters,hotels and even the family car.“I know I have been made stronger. I was homeless. My family slept on the floor and we were lucky if we gotmore than one full meal a day. Getting a shower, food and clean clothes was an everyday struggle,” Fearce said in a speech she gave at her high school graduation ceremony. Fearce overcame her day-to-day struggles by focusing on a better day. “I just told myself to keep working, because the future will not be like this anymore. And that helped me get through,” she told WSBTV.Fearce was determined to be a good role model for her younger sister. She found inspiration in her late grandmother, struggling with deadly diseases, who gave Fearce emotional support. In her junior and senior year, Fearce took both high school and college courses, missing out on the free meals she depended on so she could get to her college classes. Despite having to use her cellphone to study after the shelter lights were turned off at night, she not only graduated as valedictorian (毕业生代表) of her 2013 class with a 4.5 grade average, but was also given a ride scholarship—including a meal plan to Spelman College in Atlanta.After graduation, she worked full time for two years at the National Institutes for Health inBethesda,Maryland,doing research on drugs. Last fall, she entered Yale and set a course to earn both a PhD and medical degree.12.

And some of their schoolmates were still inside. So he and some of the other older kids took action.“One little kid was slowing everyone down with his big backpack, ” eighth grader Destiny Fain said, “so I got it off and threw it to the side and helped to make sure all the little kids weren’t fighting or pushing. ”As that was going on, sixth grader Marketez Doyle-Smith reportedly helped another classmate who had trouble in breathing because of the smoke. “We saw our friend lying on the ground,” he said, “so we took our shirts off and waved them to get him some air to breathe.”Marketez also reportedly stopped a younger kid trying to get back on the bus to search for something he’d left behind. “We're all a family,” he told reporters. “So I went back to help the little kid.”Finally everyone made it off safely, thanks to Alex, Destiny, Marketez and several other kids. By later that day, they were already being called heroes. “I really don’t see it as being a hero,” Alex said, according to The World. “I see it as the right thing to do—helping others before you help yourself.”1.

According to the last paragraph, Alex thought that heA. was not a brave student.B. had the right to do anything.C. had just done what he should do.D. hated to be called a hero by others.BSmart speakers have proven to be handy devices in hospitals, allowing patients to control independently . And now, researchers from theUniversityofWashingtonhave developed an artificial intelligence system that enables these devices to monitor heartbeats.Using technology to remotely monitor heart rates isn't new. These days most smartwatches and fitness trackers are capable of it. The good thing here is that researchers have figured out a way to use the microphones in smart speakers to do it without requiring physical contact.In a study published inCommunications Biology, the researchers had the smart speakers send out signals that couldn't be heard which were then reflected off a person's body. They then analyzed these signals to identify small chest wall motions related to heartbeats, as well as separate those signals from surrounding noise and breathing.For this particular proof — of — concept setup, the researchers tested this smart speaker on 26 healthy participants and 24 hospitalized patients with various heart conditions, including atrial fibrillation（心房颤动）and heart failure. In both cases, the smart speaker was within 28 -30 milliseconds of an ECG（心电图）,the gold standard used in hospitals to discover arrhythmia（心律不齐）.Like smartwatches with advanced heart features, using smart speakers in this way opens up the possibility for passive, remote heart monitoring. ECGs, while highly accurate, require a visit to the doctor and several electrodes （电极）to be placed on the body. They,re not capable of continuous monitoring so you're limited to what it picks up at that exact moment in time ——one reason why heart arrhythmia can be so hard to discover.Smartwatches are capable of passive, remote, continuous monitoring, but they require you to wear the device at all times to be effective. It's not something that's comfortable for everyone, especially when it comes to sleep and for those with highly sensitive skin. Another issue is that these advanced smartwatches are expensive, while smart speakers are much cheaper.“If you have a device like this, you can monitor a patient on an extended basis and then develop corresponding care plans that satisfy the patient' s needs,“ said Dr. Arun Sridhar, co — senior author on the study. "And the beauty of using this kind of devices is that they are already in people's homes.”4. What does the author focus on in Paragraph 3?A. How the smart speaker works.B. Why the smart speaker is useful.C. The advantages of smart speakers.D. The importance of the study.5. Why is heart arrhythmia difficult to find?A. ECGs are not highly accurate.B. ECGs can't monitor continuously.C. Doctors know little about heart arrhythmia.D. An ECG test is hard to operate and expensive.6. Which statement best explains the characteristics of smartwatches?A. They are comfortable to wear.B. They are friendly to sensitive skin.C. They are effective and cheap.D. They are able to monitor remotely.7. What can we infer from the last paragraph?A. We need to invent more smart devices.B. Care plans are vital to patients with heart failure.C. Smart speakers could be contactless heart monitors.D. Different devices are needed to meet patients,demands.COn September 7, 1930, Yuan Longping was born inBeijing. Fluent in English, his mother often read Friedrich Nietzsche's works to him. Influenced by his mother, Yuan Longping liked English,geography and chemistry at school. After graduating from university, he became a teacher in the countryside ofHunanin 1953.With lots of crop failures, nationwide hunger hitChinain the 1960s, making many people live a bad life. Yuan was sad and felt he must do something. Since the climate inHunanwas not friendly to growing wheat. He decided to devote himself to studying how to increase the production of rice, a basic food for over 60 percent of Chinese people. From then on, he began a lifelong connection with rice.Yuan Longping succeeded in growing the world's first high production hybrid rice (杂交水稻) variety in 1973, which could reach a yield of over 500 kg per more than 200 kg than before. For the next four decades, he continued to work on the research of hybrid rice. In 2020, hybrid rice developed by his team achieved 1,500 kg permuin two growing seasons, a new world record.Nowadays, the hybrid rice is grown in almost half ofChina's rice fields and its production accounts for 60percent of the total rice production inChina. The hybrid rice production is 20 percent more than the common kinds , the yearly increase of which feeds up to 100 million people.In 2019, Yuan Longping, known as the “Father of hybrid rice”, was awarded with Medal of the Republic,China's highest honor.Yuan Longping's biggest dream in life was to develop more hybrid rice varieties, which could be grown all over the world to help solve the global food problem. So far, the hybrid varieties he developed have been grown in over 40 countries, including theUSA,BrazilandIndia.8. What do we know about Yuan Longping according to the text?A. He began to study hybrid rice in 1973.B. He received the highest honor inChinaat 90.C. He ever taught math in the city after graduation.D. He ever hoped Chinese would be free from hunger.9.
