It has also entered international organizations of civil aviation, maritime affairs, search and rescue satellites and mobile communication.BDS-based services have been successfully applied in land mapping, precision farming, digital development and smart port construction in member countries of ASEAN, South Asia, Eastern Europe, West Asia and Africa.1. What can we learn from this passage?A. The total number of 5G phones has reached a new level.B. Kunlong, unlike SH-5, is not just for military purposes.C. Technologies mentioned above need more cooperation with others.D. BDS-based services have been provided for users in many countries.2. Which of the following is most probably related to agriculture?A. 5G phonesB. BDS-based servicesC. AG600 seaplaneD. Beriev Be-2003. If your friend did a course in marketing management, he may choose a job in a ________.A. 5G technology related marketB. large amphibious aircraftC. BDS-based projectD. China Satellite Navigation OfficeBIn order to help discover spoilage and reduce food waste for supermarkets and consumers, researchers have developed new low-cost, smart phone-linked, eco-friendly spoilage sensors for meat and fish packaging.One in threeUKconsumers throw away food just because it reaches the use-by date, but 60% of the £12.5 billion-worth of food we throw away each year is safe to eat.The researchers, whose findings were published in ACS Sensors, say the sensors could also eventually replace the use-by date—a widely used indicator of being fresh and eatable.The sensors cost two US cents each to make. Known as “paper-based electrical gas sensors (PEGS)”, they detect spoilage gases like ammonia (a poisonous gas with a strong unpleasant smell) in meat and fish products. The information provided by the electronic nose is received by a smart phone, and then you can know whether the food is fresh and safe to eat.The Imperial College London researchers who developed PEGS made the sensors by printing carbon electrodes onto a special type of paper. The materials are eco-friendly and harmless, so they don’t damage the environment and are safe to use in food packaging. The sensors, combined with a tiny electronic system, then inform nearby mobile devices, which identify and understand the data about spoilage gases.Lead author Dr Firat Guder of Imperial’s Department of Bioengineering, said, “Although they’re designed to keep us safe, use-by dates can lead to eatable food being thrown away. They don’t always reflect its actual freshness. In fact, people often get sick from food-borne diseases due to poor storage, even when an item is within its use-by date.”“These sensors are cheap enough so we hope to see supermarkets using them within three years. Our goal isto use PEGS in food packaging to reduce unnecessary food waste.”The authors hope that PEGS could have applications beyond food processing, like sensing chemicals in agriculture, air quality, and detecting disease markers in breath like those involved in kidney disease.4. What is the function of PEGS according to the text?A. To improve the taste of foods.B. To improve the service of stores.C. To help supermarkets store foods.D. To help people test food freshness.5. What role does the smartphone play while PEGS are functioning?A. It acts as an electronic nose.B. It reads the data collected by PEGS.C. It helps print the gas sensors onto paper.D. It discovers the spoilage gases from foods.6. What does Dr. Firat Guder say about use-by dates?A. They are not completely reliable.B. They can help reduce food waste.C. They are based on scientific research.D. They are not accepted by the consumers.7. What does the author mainly talk about in the text?A. The process of researching spoilage sensors.B. A new technology in packaging to reduce food waste.C. The application of spoilage sensors beyond food processing.D. The influence of use-by dates on supermarkets and consumers.CIt’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 got more 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 thathelped 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.8.

Chelesa Fearce: A Girl of Many TalentsDWhen I was a boy, there was but one permanent ambition among my comrades in our village on the west bank of Mississippi River. That was, to be a steamboat man. We had temporary ambitions of other sorts, but they were only temporary.My father was a justice of the peace, and I supposed he possessed the power of life and death over all men and could hang anybody that offended him. This was distinction enough for me as a general thing；butthe desire to be a steamboat man kept intruding, nevertheless. One of our boys in town, who went away and was not heard of for-a long time, turned up as apprentice engineer on a steamboat. This thing shook the bottom out of all my Sunday—school teachings. That boy was notoriously worldly, and I was just the opposite. There was nothing generous about this fellow in his greatness. He would always manage to have a rusty nail to scrub while his boat stopped at our town, and he would sit on the inside guard and scrub it, where we could all see him. And wherever his boat was laid up he would come home and show off in the town in his blackest and greasiest clothes, so that nobody could help remembering that he was a steamboat man; and he used all sorts of steamboat technical terms in his talk, as if he were so used to them that he forgot common people could not understand them.This creature's career could produce but one result, and it was speedily followed. Boy after boy managed to get on the river. Despite many choices, pilot was the grandest position of all. The pilot, even in those days of trivial wages, had a princely salary—from 150—250 dollars a month, and no board payment.But our parents would not let us and our worry was the next year would find us hunting for jobs with low pay again. So by and by I ran away. I said I never would come home again till I was a pilot and could come in glory.12. Why does the writer mention his father's job in Paragraph 2?A.

The boy talked in a way to make others feel jealous.B. The boy's experience made other boys follow suit.C. The pilot's salary was ly high but without meals covered.D.
