1.化学与环境、工农业生产等密切相关,下列说法不正确的是A. 浸有酸性高锰酸钾溶液的硅藻土可用于水果保鲜B. NaCl不能使蛋白质变性,所以不能用作食品防腐剂,可用来合成可降解塑料聚碳酸酯C. 捕获工业排放的CO2D. 在葡萄酒中添加微量SO作抗氧化剂,可使酒保持良好品质2【答案】B【详解】A. 乙烯是水果的催熟剂,高锰酸钾溶液有强氧化性,能氧化乙烯,浸泡过高锰酸钾溶液的硅藻土可用于水果保鲜,故A正确;B. 氯化钠虽然不能使蛋白质变性,但有防腐功能,故B错误;C. 利用CO合成聚碳酸酯类可降解塑料,实现“碳”的循环利用应用,减少二氧化碳的排放,故2C正确;作抗氧化剂,故D正确;D. 二氧化硫是还原剂,在葡萄酒中添加微量SO2故答案为B。
2.下列实验操作能达到实验目的的是A. 用装置甲验证NH极易溶于水3B. 用50mL量筒量取10mol·L-1硫酸2mL,加水稀释至20mL,配制1mol·L-1稀硫酸C. 用pH试纸测量氯水的pHD. 用装置乙制取无水FeCl3【答案】A【详解】A. 将胶头滴管中的水挤入烧瓶,若氨气极易溶于则烧瓶内压强降低,气球会鼓起来,可以达到实验目的,故A正确;B. 稀释浓硫酸时要把浓硫酸加入水中,且不能在量筒中进行,故B错误;C. 氯水中有次氯酸具有漂白性,不能用pH试纸测其pH值,故C错误;D. 氯化铁易水解生成氢氧化铁和HCl,加热促进水解,而且盐酸易挥发,所以蒸干最终得到氢氧化铁而不是氯化铁,故D错误;故答案为A。

She took it home and planted it in her home garden. It didn’t even take her long to come up and begin to grow. Bu t as friends came over, they pointed out that it was bigger than any of theirs. And it grew so much that the cabbage ended up weighing 40 pounds! Katie then decided that she could use this cabbage to do something nice for the community. So she took the huge cabbage to a local soup kitchen, where they used it, and cooked it with ham and rice. And because of her cabbage, 275 people were fed.She began to realize that gardening and helping people is what she likes to do most. So, she decided to start her first garden on a plot of land donated by her school.“I think if more kids get to experience gardening they would find out how cool it is and how many people can be fed if you donate your produce,” said Katie. Now, just 9 years later, Katie is 18 years old, and has set up her own business called “Katie’s Krops” with the help of her family friends.But this doesn’t even come close to the other amazing part. She has raised over 200,000 dollars! And there are over 100 Katie’s Krops within 33 states in the United States. She loves gardening and loves inspiring other children to experience the joy of gardening as well. As of today, her first garden is still doing amazing and is even responsible for supplying over 3,000 pounds of produce donated to local charities. Her goal now? To get 500 gardens across all 50 states.24.How did Katie deal with her first cabbage?A.sharing it with her community.B.Presenting it to the school kitchen.C.Eating it with her family.D.Giving it to her friends.25.What inspired Katie Lo help others by gardening?A.The support from her school.B.The gardening and sharing experience.C.The encouragement of community.D.The admiration of her friends.26.Why does Katie suggest more children learn to garden?A.She thinks gardening is cool.B.She needs more people to help her.C.She hopes to earn more money.D.She wants them to experience the joy.27.What is the last paragraph mainly about?A.The brief introduction of Katie’s Krops.B.The amazing benefits of gardening.C.Katies achievement and future aim.D.The joy of gardening and donation.CAs the weather gets colder, we start wearing jackets, and most of us stop thinking about the sun. But the sun’s rays can be just as harmful when it’s cold and cloudy outside. “Any exposed area of your body can still get sunburned,” Dr. Apple Bodemer, an associate professor at the University of Wisconsin-Madison, told Live Science.Whether you spend a day on the slopes, skating on a pond or clearing snow out of your driveway, your face is still getting exposed to the sun’s radiation in the form of ultraviolet (紫外线) (UV) light, which can go deep into your skin cells causing DNA damage, according to Bodemer.The sun’s long ultraviolet A (UVA) waves can cause earlier aging, sunspots and wrinkles, while its short ultraviolet B (UVB) rays are known for causing skin reddening and burns.Skin damage caused by UV exposure increases over time. More exposure to radiation contributes to more severe damage, even skin cancer. In addition, snow and ice can also make sun damage worse. They reflect up to 80 percent of UV rays reaching the ground. That means you get hit from both the sky and the ground. And skiers and snowboarders increase their risk of getting sunburned even more because UV exposure increases at higher altitudes.“Generally, the biggest factor for sun-sensitivity is how pale your skin is,”he said. “But, the reality is that even the darkest individual can get sun damage.”Luckily, the solution for protecting your skin is simple: Wear sunscreen every day. Rigel recommended using sunscreen with a sun protection factor (SPF) of at least 30, and going higher at high altitudes. As a rule of thumb, SPF 30 will block 97 percent of UVB rays, SPF 50 blocking 98 percent, and SPF 100 blocking 99 percent. Whatever kind of suns creen you use, it’s important to apply SPF about once every 2 hours.Rigel also suggested sunscreens with “broad spectrum (光谱)”—to protect against both UVB and UVA rays—as well as sunscreens that are water resistant for up to 80 minutes. That way, you can go about your day without it wearing off too quickly.28.Which of the statements best describes UV lights?A.UVB lights cause much less damage to skin than UVA lights.B.Skin damage from UV lights can he totally prevented by sunscreen.C.Snow and ice make people suffer much more from UV light damage.D.People outdoors needn’t worry about getting sunburned on a cold day. 29.Which is the most vital factor as for sun damage?A.Your skin color. B.The clothes you wear.C.The altitude of your place. D.The weather when you are outside. 30.What do we know about sunscreen?A.The lower sunscreen SPF is, the better effect it will have.B.People working in high mountains need sunscreen SPF30.C.Applying sunscreen once when outside is necessary.D.Water resistant sunscreen can be applied once every 80 minutes.31.What may be the best title for the text?A.Being Exposed to Sun Rays B.Ultraviolet A & Ultraviolet B C.Getting Less Sunburn in Winter D.Different Kinds Of SunscreensDAlongside air and water, food is a necessity for human beings to survive andthrive. But it’s a lot more than that. As Mariette Dichristina of Scientific American wrote: “The most intimate (亲密的) relationship we will ever have is not with any fellow human being. Instead, it is between our bodies and our food.”Nowadays, for most people in the world’s wealthiest countries, food is a hobby, an enthusiasm, and even something fashionable.Turn on the TV in the US, UK or France, and you’ll find at least one channel feeding this popular obsession.And most of us know at least one person who thinks of themselves as a “foodie”. It’s almost impossible nowadays to check our social media apps without at least two or three photos of delicious meals appearing on our screen.But behind the fancy recipes and social media bragging (夸耀), many of us forget how much we take food for granted. This is why World Food Day is held each year.Take Kenya for example. This east African nation has been suffering terrible droughts. The result is that people are beginning to starve. Children in particular are suffering, with some of them even dying.This may seem shocking to know, especially as many cultures outside of Africa think of food in a completely different way. But even in the UK, families on low incomes are forced to use food banks—European organizations that hand out donated food to those who can’t afford to pay for it themselves.So what can we do on World Food Day? One good way to spend it would be to feel humble and appreciate what we have. After all, food is essential for survival, but not everyone is as lucky as we are when it comes to dinner time.32.According to Mariette Dichristina, what has the closest relationship with us? A.Air.
