When my family and I had just arrived in China, we went looking for a good place to eat in Beijing. A Sichuan restaurant had been recommended to us by a friend, and finally, we found it. Tired, hungry, and not knowing a word of Chinese, we had no idea how to 课后巩固 多维提能 order, so the chef just began filling our table with the best food we had ever eaten. With this, we had the pleasure of experiencing an entirely new taste：Sichuan peppercorns. The food was wonderful and different, but what was even more important was the friendship offered us. 课后巩固 多维提能 We soon moved to Shandong Province in the eastern part of North China. My favourite dish there was boiled dumplings served with vinegar. I observed that family is important to the people there. It has become a favourite traditional dish of the people in North China, where making dumplings has always been a family affair with everyone—from the youngest to the oldest—joining in to help. Later, I learnt that the most famous food in Shandong is pancake rolls stuffed with sliced Chinese green onions. 课后巩固 多维提能 Then we moved to northern Xinjiang. Some of our friends were Kazak and Inner Mongolian. These groups traditionally wandered the open range on horses. As a result, their traditional foods are what you can cook over an open fire—usually boiled or roasted meat, such as lamb kebab. 课后巩固 多维提能 Our travels then took us to South China, and then on to central China. In each place we went, we experienced wonderful local dishes, from Guangdong's elegant dim sum—small servings of food in bamboo steamers—to the exceptional stewed noodles in Henan. Everywhere, the food was as varied as the people. However, one thing is always true：Through food, Chinese people everywhere show friendship and kindness. 课后巩固 多维提能 1．What is the most famous food in Shandong? A．Boiled dumplings.　　 B．Roasted meat.

D．Nutritious and impressive. √ 课后巩固 多维提能 4 1 3 2 3．Why do people in Xiangjiang prefer their food to be cooked over an open fire? A．Because they like the flavour of boiled or roasted meat. B．Because they traditionally wandered the open range on horses. C．Because that way of cooking can bring the people together. D．Because that way of cooking can show their character. √ 课后巩固 多维提能 4 1 2 3 4．Which of the following is TRUE? A.Lamb kebab is the traditional food in Sichuan. B．In Shandong people like to cook foods over an open fire. C．In South China, making dumplings has always been a family affair.

The short answer is yes, though the longer answer is more complicated. Some of the most powerful evidence that fruit is sweeter than before comes from zoos. [综合能力提升练] 课后巩固 多维提能 In 2018, it was reported that Melbourne Zoo in Australia had stopped giving fruit to most of its animals because cultivated fruit was so sweet that it was causing tooth decay (蛀牙) and weight gain. The monkeys at the zoo were provided with a lower-sugar vegetable-based diet instead of bananas. 课后巩固 多维提能 Among fruit cultivators, the word “quality” is now routinely used as an equal for “high in sugar” (though firmness, color and size are also considerations). In 2010, in an article looking at ways to enhance the sweetness of fruit using “molecular (分子的) approaches”， a group of plant scientists of the Republic of Korea wrote that “in general, the sugar content” of many fruits is now higher than before “owing to continuous selection and breeding”. Modern apple varieties, the scientists noted, were on average sweeter than older ones. 课后巩固 多维提能 Cultivation isn't the only reason that modern fruit is sweeter; there's also climate change. Research from Japan found that since the 1970s, with rising temperatures, Fuji apples (which were already a sweet variety) have become significantly sweeter and softer. The lead researcher, Toshihoko Sugiura, said that “if you could taste an apple harvested 30 years ago, you would feel the difference”． 课后巩固 多维提能 It is sometimes claimed that the sweetness of modern fruit is not due to higher sugar content so much as the fact that the bitterness and sourness of wild fruit have been steadily cultivated out of it. There's a grain—but only a grain—of truth in this. Studies of wild apples do indeed suggest that some ancient varieties were just as high in sugar as a modern Pink Lady or Honeycrisp. The difference is that there was much wider variation in sugar content across wild apples, whereas the modern supermarket apple seldom drops below a certain level of sweetness. 课后巩固 多维提能 【解题导语】　本文是一篇说明文。文章介绍了现代农业技术使得水果比以前更甜。 课后巩固 多维提能 1．Why did Melbourne Zoo stop giving fruit to most of its animals? A.The animals preferred a vegetable-based diet. B．Modern fruit did great harm to animals' teeth. C.The sugar content of modern fruit is lower than before. D．The flavor of modern fruit was not good for the animals. √ 课后巩固 多维提能 4 5 6 7 8 2 3 1 解析：细节理解题。根据第二段中的“In 2018, it was reported that Melbourne Zoo...it was causing tooth decay and weight gain.”可知，现代水果对动物的牙齿有很大的危害，因此动物园停止了给动物供应水果。 课后巩固 多维提能 4 5 6 7 8 2 3 1 2．What can we learn from paragraph 3? A.The sugar content is not breeders' first priority. B.Sweeter fruits are just a result of natural selection. C．The sweetness of modern apples is equal to the average of older ones. D．Molecular approaches are adopted to add the sweetness of modern fruit. √ 课后巩固 多维提能 4 5 6 7 8 1 3 2 解析：细节理解题。根据第三段中的“In 2010, in an article...using ‘molecular approaches’”可知，现代水果采用分子方法来提高甜度。 课后巩固 多维提能 4 5 6 7 8 1 3 2 3．What do studies of wild apples in the last paragraph suggest? A．Apples of old species tasted less sweet. B．The sugar content of wild apples varied greatly. C.The sweetness of modern apples is of the same level. D．Fruit is sweet because bitterness in it has disappeared. 解析：细节理解题。根据最后一段中的“The difference is that there...apple seldom drops below a certain level of sweetness.” 可知，野生苹果的含糖量变化很大。 √ 课后巩固 多维提能 4 5 6 7 8 1 2 3 4．What's the best title for this passage? A．Modern or Old: Which Is Better? B．Modern Fruit: Sweetness Is Quality C．Fruit Is Sweeter: It's Not a Misconception D．Melbourne Zoo: Animals Stop Eating Fruits 解析：标题归纳题。根据第一段内容并通读全文可知，文章介绍了现代农业技术使得水果比以前更甜。C项最适合作文章标题。 √ 课后巩固 多维提能 5 6 7 8 1 2 3 4 B (2026·河北迁安高二上学期期中)For coffee lovers, the future is shaping up to be bitter and more expensive, as climate change roasts the world's key growing regions. Farmers have to dig deeper to get water． 课后巩固 多维提能 Tougher growing conditions have led Vietnamese farmers to question the value of coffee as a cash crop, with some pulling out their trees to plant black pepper and other tropical fruits. Reduced supply has already pushed the Robusta (coffee) price in 2024 to the highest level since at least 2008—and still, rising temperatures mean future production will fall short. 课后巩固 多维提能 Regions suitable for crop production reduce globally primarily due to increased heat. Hardier varieties are expected to fare better, and for coffee that means strong, earthy Robusta. Researchers found that it would be necessary to adapt, including by replacing Arabica (coffee) with hardier Robusta. However, Robusta is not a silverbullet for climate change. Researchers are still learning Robusta's limits though it's more tolerant to heat and to some diseases and pests. 课后巩固 多维提能 Prolonged dry periods in Vietnam and lack of irrigation water in recent years have already severely affected the productivity of Robusta coffee farms in the Central Highlands, according to a study.In an October report, World Coffee Research (WCR) said the world may face Robusta shortages in 2040 of as much as 35 million bags, on the basis of rising consumption trends and the impact of climate change on production. The world currently produces close to 80 million bags of Robusta a year. 课后巩固 多维提能 Farmers are seeing the benefit of more sustainable farming practices. Farmers have cut back on chemical fertilisers and provided shade for coffee shrubs (灌木) so they're less exposed to the burning sun. They have also planted black pepper to diversify. When applying this, they have more income, and they can save a lot of labour. Lien, who began planting coffee nearly thirty years ago, said, “Now I see my coffee better developed, with better yields.” 课后巩固 多维提能 【解题导语】　本文是一篇说明文。文章介绍了气候变化对咖啡种植的影响，包括种植条件恶化、产量下降、价格上涨等问题，同时介绍了农民们为应对这些问题所采取的可持续种植方法。 课后巩固 多维提能 5．What troubles farmers most when they plant coffee? A.Lower price and less labour. B．Poor quality with bitter flavor. C．Heat pressure and water shortages. D．Reduced productivity of coffee. 解析：细节理解题。根据第一段内容和第四段中的“Prolonged dry periods...according to a study.”可知，农民在种植咖啡时面临的主要问题是高温压力和水资源短缺。 √ 课后巩固 多维提能 4 6 7 8 1 2 3 5 6．What does the underlined phrase “silver bullet” in paragraph 3 probably mean? A.Essential alternative. B．Effective solution. C．Secure mode. D．Scientific conclusion. √ 课后巩固 多维提能 4 5 7 8 1 2 3 6 解析：词义猜测题。根据第三段中的“Researchers found that it would be necessary to adapt...to heat and to some diseases and pests.”可知，罗布斯塔咖啡虽然对高温和一些病虫害的耐受性更强，但并不是应对气候变化的完美解决方案。由此可推知，“silver bullet”在此处应指“有效的解决方案”。 课后巩固 多维提能 4 5 7 8 1 2 3 6 7．What's the author's attitude towards the farming practices？　 A．Critical. B．Supportive. C．Objective. D．Opposed. 解析：观点态度题。根据最后一段中的“When applying this...‘Now I see my coffee better developed, with better yields.’”可知，作者通过说明可持续种植的益处和实际成效，表达了对这些种植方式的支持。 √ 课后巩固 多维提能 4 5 6 8 1 2 3 7 8．What can be inferred from the last paragraph? A.Dry periods affect the productivity of Robusta coffee farms. B.Robusta coffee price will stabilize soon. C.Vietnamese farmers are abandoning coffee farming. D.Sustainable farming is becoming popular. 解析：推理判断题。根据最后一段中的“Farmers are seeing...and they can save a lot of labour.”可知，农民们看到了可持续种植方法的好处，并开始采用这些方法，由此可推知，可持续种植正在变得流行。 √ 课后巩固 多维提能 4 5 6 7 1 2 3 8 Ⅱ.完形填空 In a city of wealth, comfort and fine food, there's a quiet alley (小巷) where passers-by often take several photos.Sharing _______ with elegant cafes and world-class bars, a tiny fruit and vegetable _______ seems to have been transported from a country road far away.But what lets the stall (货摊) even more ____________ in the heart of the city is that payment is on the honor system—customers just toss coins into an old mailbox—and most of the items on offer are at a low _______ in a neighborhood where fresh food usually goes for much, much more.
