1 . Mosquitoes can carry various diseases and one of the most popular is dengue (登革热). Dengue is caused by any one of the four related viruses spread by mosquitoes, because of which numerous Filipinos died. One of the easiest ways to prevent mosquitoes is to use repellents. In the market, there are many commercial mosquito repellents available. The commonly used repellent in the Philippines is quite unaffordable. Meanwhile, it contains chemicals that may cause irritation (刺激). These account for why researchers seek to develop an alternative mosquito repellent.
The researchers plan to use natural components. Since the component is natural, the new mosquito repellent to be made from it is effective yet inexpensive and poses no risks to health or environment. One of the major components being explored is from lemongrass.
Lemongrass has natural anti-microbial features, suitable for use on various types of skin infections, usually as a wash, and is especially effective on skin diseases. It has mosquito repelling effects and is used to make a mosquito repellent. In using this product, you will spray it over all exposed skin areas. Contact with eyes should be avoided. If irritation occurs, wash off immediately and discontinue using. The very importance of this product is to prevent the spread of multiple diseases caused by mosquito bites. The new mosquito repellent containing lemongrass extract (提取物) also helps control the outbreak of other insect-borne diseases such as Malaria, Lyme Disease and West Nile Fever. After all, lemongrass is a popular plant found commonly in the country and its extract is used for medicinal and food products.
The new study is significant because there’s an increasing number of deaths concerning mosquitoes. While there are alternative solutions, Filipinos cannot deny their brothers and sisters living in poverty cannot afford to buy repellents. Yet, currently the researchers aim to test how effective their natural product is in repelling mosquitoes within households. This initial study will evaluate the product’s effectiveness before further trials in broader applications.

5 . My mom is one of the least wasteful people I know. She always brings her own metal containers to buy basic foods like rice and flour.
One effective way is to conduct a review of household rubbish. List the rubbish by room or by activity.
Reyond repurposing food containers, explore ways to save household items before throwing them away. Maybe you can mend an old pair of jeans instead of buying a new pair. Or maybe you can cut up old T-shirts into rags, which is what my mom used to do with my dad’s old T-shirts.

I didn’t like Del so much. He always called me the nickname “Germy”, which meant “dirty”, instead of my real name “Jamie”. Besides, he was known as a trouble-maker in school. So when the head teacher Mr. Smith asked Del to come to his office, I naturally thought that Del had done something mean to someone. Through the window, I caught sight of a smaller boy crying. Del seemed unhappy, too.
He did not return to class that day. All of us were discussing what had happened to him. What else could such an annoying boy do? “He must have hit the boy and was sent home,” I whispered to my friends. Their eyes widened. It felt good to see them so interested in what I said.
The next morning, the whole school was talking about Del being expelled(开除) for beating up a kid. I was surprised that my assumptions were passed on so quickly. So when Del walked into the classroom, all the kids were shocked. The kids next to him shift ed their desks away. “What’s your problem?” Del asked. “I don’t want you to attack me,” one kid said. Some laughed. “Yeah, I might,” said Del. I could tell he was joking, but many kids thought he admitted he did beat up someone.
During recess(课间休息), Del tried to join the kickball game. “Neither team wants you,” one of the players said. “Why?” Del asked, looking confused. “I always play with you guys.” They ignored him and went on playing. Del sat by himself while the rest of the school enjoyed their recess away from him. Del looked lonely and sad, much different from before. I started to feel sorry for him.
Later that day, I learned what really happened. The kid was Del’s little brother and he was crying because their mother fell ill and was sent to hospital. I felt even sorrier for what I said before. I started a rumor(谣言).

7 . China’s growing excellence in scientific and medical research is playing a major role in the global war on pathogens (病原体) and infectious diseases, according to Alain Merieux, chairman and CEO of French Conglomerate Institute Merieux.
He first visited the country in April 1978, several months before the central government launched its transformative reform and opening-up policy. Since then, he has spent decades dedicated to cooperation in the health sector, eventually leading to the opening of China’s first P4—photolithographic pattern plated probe—laboratory in 2015. The lab, which is based in Wuhan, Hubei Province, has the highest biosafety standards in the world, allowing researchers to study the most dangerous viruses, including Ebola.
“In the health field, which is the one I know best, China has been able to address major issues over the past 40 years,” Merieux said, “providing access to healthcare for everyone in an enormous country; fighting against the major threats represented by pathogens, respiratory diseases and cancer; and preventing food-borne health risks.”
“The country has particularly excelled in terms of infrastructure (基础设施), as the creation of highways, airports and high-speed trains has completely changed the country,” he said.
A.He wants to contribute more to the whole world. |
B.He also praised the overall changes seen in the nation. |
C.This fight must be global, since pathogens cut across borders. |
D.His company was established by his grandfather in Lyon in 1897. |
E.The project has become a symbol of Chinese-French collaboration in public health. |
F.His aim is to improve diagnosis and treatment of major infectious diseases in China. |
G.There has also been remarkable progress in scientific research, as well as academic and science. |
