Some are known to cause hyperactivity (多动症) in some children, affecting their ability to learn. But regulatory agencies around the world don't necessarily agree on which food dyes are a problem, or why. That may soon change. A peer­reviewed report by California's Office of Environmental Health Hazard Assessment concluded that artificial food dyes “cause or worsen neurobehavioral problems in some children” and that the current levels regarded safe for consumption by the federal government are too high. 课后课时作业(三) 9 California is now considering requiring warning labels on food products and dietary supplements containing the seven most commonly used artificial dyes. The warning label requirement would put California on__par__with the European Union, which since 2010 has required food products containing certain artificial food dyes to carry warning labels about their negative effect on activity and attention in children. Artificial dyes are used in foods for one reason: to make products look prettier. Bright colors make candies appealing, especially to kids. But dyes are also in chocolate cake mixes, sala dressings and other products that don't seem to cry out for a color boost. 课后课时作业(三) 10 In Europe, it was the 2010 label lawmaking that triggered companies' decisions to reformulate. “If you're a company, you do not want to put a warning label on your product，” says Lefferts, an environmental health consultant. Warning labels are why European Starburst Fruit Chews are now colored with natural products, not the artificial dyes that brighten their North American counterparts (同类商品)． 课后课时作业(三) 11 Given that artificial food dyes are excessively used, we need to be more cautious. After all, we don't dye fresh fruits and vegetables, but we do dye candy and sprinkles, points out Joe Schwarcz, a chemistry professor at McGill University in Montreal. “The foods in which you find food dyes are foods that are poor in nutrition，” he says. “If you limit foods that contain food dyes, you automatically make your diet better.” 篇章导读：本文是一篇说明文。文章主要介绍了含有人工食用色素的食品对身体的危害。加州政府出台新规，要求含有人工色素食品要贴上警告标签。这一举措将提高人们的健康意识，也让食品公司对使用色素做出相应的调整。 篇章导读 课后课时作业(三) 12 1．What can we learn about artificial food dyes from Paragraph 1? A．A report confirmed their negative effects. B．The fact that they are harmful is newly revealed. C．Regulatory agencies consider them a serious problem. D．The federal government thinks their current standard too high. 解析：推理判断题。根据第一段中的“A peer­reviewed report ... in some children’(加州环境健康危害评估办公室的一份同行评议报告得出结论，人工食用色素‘会导致或加剧一些儿童的神经行为问题’)”可推知，一份报告证实了人工食用色素的负面影响。故选A。 答案 解析 课后课时作业(三) 13 2．What does the underlined part “on par with” in Paragraph 2 mean? A．In opposition to. B．Ahead of. C．In line with. D．Behind. 解析：词义猜测题。根据画线部分所在句“The warning label ... in children.”及上文“California is now considering requiring warning labels on food products”可知，加州也要和欧盟一样要求在食品上贴上警告标签，由此可推知，on par with意为“保持一致”。故选C。 答案 解析 课后课时作业(三) 14 3．Which might be a possible result of the new rule according to the article? A．Food companies will stop coloring their products. B．More fresh fruits and vegetables will appear in the market. C．Food companies may replace artificial dyes with natural products. D．It will be hard to find packaged foods without warning labels of dyes. 解析：推理判断题。根据倒数第二段中的“Warning labels are ... North American counterparts (同类商品)．”可推知，新规定产生的可能结果是，食品公司为了公司的长久发展，可能会使用天然色素来代替人工色素。故选C。 答案 解析 课后课时作业(三) 15 4．What's Joe Schwarcz's attitude towards artificial food dyes? A．Approving. B．Concerned. C．Neutral. D．Indifferent. 解析：推理判断题。根据最后一段中的“Given that ... McGill University in Montreal.”可推知，Joe Schwarcz (乔·施瓦茨)对含有人工色素的食物持担忧的态度。故选B。 答案 解析 课后课时作业(三) 16 Ⅴ　语法填空 (2024·吉林省四平市高二下期中质量监测)Over the years, digital cameras have been getting smaller and smaller, making it __1__ (easy) for people to snap (拍照) a picture, while now researchers have developed the world's largest digital camera.

They were on a field trip to the forest as part of a science lesson. Over there, they met the forester (护林人), Victor. When William learned Victor lived in a simple wooden house there for years, he laughed at him with his friends. Then, they passed by an entrance to a cave. William wanted to explore inside the cave, but his teacher didn't allow it. “I'll come back here，” he thought. On the way back to school, he remembered the exact location of the cave. 小精读 The next day, William asked his four friends to the cave together. They told their parents they would go to the library and return home in the evening. None of the teenagers told their parents about their plan to visit the cave. When the teenagers reached the cave, they left their schoolbags outside to reduce the burden. One by one, they entered the cave. Just when they took a few steps inside, some rocks from the cave wall fell and blocked the entrance. “How are we going to get out now？” one of the teenagers Sarah shouted. William had an idea and said, “Maybe we can try digging through the fallen rocks with our hands to reach the entrance.” But realizing getting out of the cave only by their hands was impossible, they had great fear. The sun was about to go down. The teenagers started calling for help, but nobody could hear them. The teenagers were losing hope. 小精读 Victor happened to pass by the entrance to the cave, and five schoolbags caught his attention. He also heard some sounds coming from inside the cave. “Who's in there？” Victor shouted. “I'm William! We came here yesterday with our teacher！” William replied instantly. “Help us, please! We are stuck! Sarah can't breathe here because of fear.” “Okay, calm down, children！” Victor said. “I'll help you get out！” 小精读 Victor immediately called the first­aid center and rushed home. After a little while, Victor got back to the entrance with a shovel and a flashlight. “Hey! I'm back！” he shouted, assuring the kids that he would rescue them. Then, he began digging through the rocks at the entrance. It wasn't easy for one man to dig through the rocks, but he was trying his best. Meanwhile, William and his friends tried to stay calm and told Sarah not to worry. A few minutes later, William and his friends could see the flashlight shine through the cave's entrance, which made them excited. 小精读 Soon, the teenagers walked outside the cave and took a deep breath in the fresh air. Fortunately, Sarah felt better. Just then, medical workers arrived and examined the children carefully to make sure they were OK. William looked at Victor who was worn out and regretted making fun of him when they first met. He apologized to the great forester and thanked him for rescuing him and his friends. Later, the teenagers' parents arrived and were grateful to Victor for his timely rescue. Also, the teenagers promised their parents they wouldn't lie and take such a dangerous adventure again. 小精读 入口，进口 负担 即将要做某事 取笑某人 小精读 A few minutes later, William and his friends could see the flashlight shine through the cave's entrance, which made them excited. 本句主干是William and his friends could see the flashlight shine，为“主谓宾宾补”结构。A few minutes later是介词短语作__________，and连接________和____________作并列主语，which引导____________________从句。 时间状语 William his friends 非限制性定语 小精读 第一步： ____________________________________________________________________________________________________________________ 第二步： ______________________________________________________________________________________________________________ 第三步： ______________________________________________________________________________________________________________ William (威廉姆)在一次科学课的森林实地考察中遇到了朴实的护林人Victor (维克多)，William却嘲笑对方的住所平庸。 没有告知家长，William和朋友们决定去森林中的一个洞穴探险，不巧，落石堵住了洞口，一行人被困在洞穴里。 Victor路过，解救了大家，William意识到自己嘲笑他人是不对的行为，也记住了随意冒险是很危险的举动。 小精读 ________________________________ 礼貌是一个人最好的名片。 小精读 R $$
