Recently there has been a report about a woman from Australla who can remember almost every detail(细节) of all the events in her daily life.Rebecca Sharrock, 25, is one of just 80 people worldwide who have been identified ( 确定) as having Highly Superior Autobiographical Memory (HSAM,超级自传体记忆症). It means she can remember every small event-which most people would forget within days-as if it had happened just minutes ago.“I remember my mum putting me in the driver’s seat of a car and taking a picture of me when I was 12 days old”, she said. "That's my earliest memory. I remember every day since then. I can't tell all the dates exactly because I was too young to understand calendars, but I remember what I did that very day, what the weather was like and so on.”Rebecca can also re-experience taste. If she’s eating something that she doesn't like, she thinks about Black Forest cake, her favorite food, and the memory will be so strong that she can nearly"taste"it.However，sometimes her memories prove(证明)to be painful. Because they're not just events that she remembers. “ When I relive(再体验) memories，the feelings return, too,” Rebecca said.“ For example，I remember falling over when I was three at my grandparents’ house and hurting my left knee. Talking about it now, I feel painful in my left knee.”“At night, I have to sleep with the radio/recorder and a soft light on，” she added. “ If it's toodark or quiet, my mind would be filled with all these memories and I can’t sleep.”31. Which is NOT TRUE about Rebecca?A. She has special memories.B. She is from Australia.C. She is 25 years old.D. She can remember every detail of all the events.32. What happened to Rebecca on the day when she was 3 years old?A. She was identified as having HSAM.B. Her mother put her in a car and took a picture of her.C. She started to understand calendars.D. She hurt her left knee at her grandparents’ house.33. Whenever she is reliving her memories, _______.A. she is happyB. she experiences the feelings againC. she feels pain in her kneesD. she can taste her favorite food34. What is the result of having HSAM?A. She can remember every event in her daily life.B. She can re-experience taste.C. She can relive feelings.D. All the above.35. From the passage，we can infer(推断)that_______.A. HSAM can do her good, but it also brings her painB. she feels painful if she recalls her experiencesC. she can fall asleep while she is re-experiencing memoriesD. HSAM can greatly improve her living conditionsIV.词汇运用(每小题1分，共5分)36. Food safety________(影响) our everyday life.37. I plan to travel to several________(欧洲) countries this summer vacation.38.

英语作文 food safetyFood Safety。

Food safety is a critical issue that affects everyone, as we all rely on the food we consume to be safe and free from contamination. Ensuring the safety of our food supply is a complex and multifaceted challenge that requires the cooperation and vigilance of government agencies, food producers, and consumers alike.One of the primary concerns in food safety is the presence of harmful bacteria, viruses, and other pathogens that can cause foodborne illnesses. These can be found in a variety of foods, including meat, dairy products, fruits, and vegetables. In order to minimize the risk of contamination, it is essential for food producers to adhere to strict hygiene and sanitation practices throughout the production and distribution process. This includes maintaining clean facilities, proper refrigeration and storage, and regular testing for pathogens.In addition to pathogens, chemical contaminants can also pose a threat to food safety. Pesticides, antibiotics, and other chemicals used in agriculture can potentially end up in the food supply and pose health risks to consumers.It is important for regulators to set and enforce strict limits on the use of these chemicals, and for consumers to be aware of the potential risks and make informed choices about the food they purchase and consume.Another aspect of food safety is the issue of food labeling and transparency. Consumers have the right to know what is in their food and how it was produced. This includes information about potential allergens, additives, and preservatives, as well as where the food was grown or raised. Clear and accurate labeling allows consumers to make informed choices about the food they buy, and also helps to hold food producers accountable for the safety and quality of their products.In recent years, the globalization of the food supply chain has added another layer of complexity to the issue offood safety. With food being transported across borders and continents, there are increased opportunities for contamination and the spread of foodborne illnesses. This has led to the development of international standards and regulations for food safety, as well as increased cooperation and information sharing between countries to ensure the safety of imported and exported foods.While there are many challenges in ensuring food safety, there are also many opportunities for improvement. Advances in technology, such as DNA testing and blockchain, have the potential to revolutionize the way we track and trace food products from farm to table, making it easier to identify and address safety issues. Additionally, increased consumer awareness and demand for safe and sustainably produced food has the potential to drive positive change in the food industry.Ultimately, food safety is a shared responsibility that requires the cooperation and diligence of all stakeholders, from food producers and regulators to consumers. By working together to address the challenges and opportunities infood safety, we can ensure a safer and more secure food supply for everyone.。

Nowadays, the food industry has become an important industry in many industries. For food, safety is the most basic requirement, in the three elements of food (safety, nutrition, appetite), safety is the primary standard for consumers to choose food. In recent years, in the world's emerging food safety incidents, such as the "mad cow disease" and "foot-and-mouth disease" event, the Belgian dioxin incident, to the domestic tonyred, diaobaikuai, poisonous rice, toxic oil, malachite green, clenbuterol, taitouwawa, melamine and three recent poison French fries and beef extract and other events, the food security situation in China and the world is very serious. The increasing environmental pollution and frequent food safety incidents have posed a great threat to human life and health, and have become a hot issue.I. current situation of food safety in ChinaAccording to the information I have collected, the problems existing in China's food safety are divided into the following categories: 1. Food safety problems caused by chemical pollution. Veterinary drug residues, environmental pollutants and biochemical pollutants mainly include agricultural toxins.(1) the threat of environmental pollution to food safety, rivers, lakes, coastal waters and other pollution is an important factor leading to food insecurity.

(2.) the use of chemical fertilizers such as pesticides, veterinary drugs, growth regulators and other agricultural chemicals caused by the source pollution caused by cultivation and cultivation has brought great risks to food safety from the source. The annual amount of nitrogen fertilizer use in China is as high as 25 million T, and the pesticide is more than 1 million 300 thousand T, and the per unit area use is 3 times and 2 times of the world average. Excessive application of chemical fertilizer can increase nitrate accumulation in vegetables and cause harm to human body. The improper use of veterinary drugs, biological growth hormone and exceed the standard accelerator of pesticide residues, and the pollution of aquaculture environment, resulted in a largenumber of hazardous substances containing food, vegetables, fruits, meat products, dairy products and other substandard products flooded the market. 2. Foodborne diseases caused by microorganism and its toxin pollution. Food poisoning caused by pathogenic microorganisms and their toxins is present in large numbers. For example, Salmonella, Vibrio, intestinal bleeding, Escherichia coli and so on. 3, food processing, food safety problems caused by the production process. The food safety problem caused by food processing production process mainly includes the production and processing enterprises failed to strictly in accordance with the process requirements, food safety standards, such as microbial killing incompleteness of pathogenic microorganisms multiply, excessive use and abuse of food additives. In addition, the safety of health food, genetically modified food and irradiated food has attracted more and more attention. 4, illegal production and management of food safety problems brought by undocumented, unlicensed illegal production and management of food remains a serious problem, such as food production enterprises resort to deceit against legal consciousness, the production of light weight, health law phenomenon brings great risk to food safety.At the same time, the relevant departments of supervision and promotion of food safety also chilling. 1, propaganda is not enough.One embarrassing fact is that on the one hand, consumers are demanding safety; on the other hand, they are very low on safety food. According to the survey of Beijing, Shanghai, Guangzhou, Chongqing city l863 4 consumers, 50% of people said that foodsafety will not pay special attention in the choice of daily food, more than 70% of the respondents did not understand the food safety knowledge to distinguish. With the lack of honesty and money worship in the whole society at present, the phenomenon of over extended, extended use and counterfeit safety food labeling is more common, and the information asymmetry between consumers and producers is asymmetric. There are problems of lax enforcement, but not enough publicity. Propaganda is to build an image of the entire safety food. 2, there is no unified management. There are many kinds of food on the market, which are difficult to distinguish and confused. The main reason is that the food management authority is not unified, inconvenient management, and some even appeared the phenomenon of mutual exclusion between the management. There is a lack of awareness of the link between safe food and environmental problems. Consumers can not tell which food is good or what is wrong, and sometimes it is difficult to explain clearly. From the safe food certification agencies, organic food certification, environmental protection departments, green food, pollution-free food, agricultural sector. 3, lack of systematic research on key technologies and supporting measures. In our country, the production technology of various kinds of safe food is lack of thorough and systematic research, such as animal and plant planting, breeding technology, processing technology, storage technology, etc.. Whether it is key technology, the integration of supporting technology, or product quality, etc., need to be further studied and developed. In addition, in the detection technology, whether the means of detection, or the distribution of detection points are still inadequate. 4, there is no uniform evaluation criteria. In terms of environmental quality, the Ministry of agricultureindustry standard NY5010 - 2001 and the State Administration of Quality Supervision Inspection and quarantine standards GB/T18407.1 2001 provisions are made of pollution-free vegetables and environmental quality, but the degree is not very favorable, such as environmental air standard value, the national standard limit on the concentration of lead in atmosphere the industry standard is not stipulated in this. In addition, there are obvious differences in the sampling period and frequency of air sampling points. On the soil environment, the lead content limit industry standard value: the value of pH <6.5 for 250 mg/kg, pH value in the 6.5~7.5 300 mg/kg, pH value of >7.5 was 350 mg/kg; and the national standard were 100150150 mg/kg difference, appeared many such problems in the two standard, it is difficult to follow in the actual assessment.Two, to solve the problem of food safety in ChinaFood safety is a whole strategic system, involving many departments and coordinating with each other, so as to establish a relatively perfect food safety strategy system. Food safety is not only related to people's quality of life, physical and mental health problems, but also to participate in international agriculture and even food products trade competition is also important. The establishment of the system of China's food security strategy, need to improve the legal system for the protection, in order to monitor the strict management system as a means to produce food safety technology as the foundation, and these are required by the State Department to implement unified management.In view of the existing problems, the following aspects should be considered in the establishment of our country's safe food strategy system:1, management authority should be clear. To clear responsibilityCountries from the macro regulation, responsible for food safety by specialized departments, unified authentication, unified management, unified standards and classification; support the development of food industry in policy, and improve the market laws and regulations and market price system.2, strengthen management and guide healthy consumptionThe establishment of food safety system needs many cooperation and coordination. It can not be separated from the input departments, production departments, management departments, technical monitoring departments and all social groups. Therefore, we should strengthen publicity and leadership so as to raise the people's awareness of green consumption and consumption.3, strengthen the research, application and popularization of food safety technologyFood safety is a system engineering, it involves many subjects, such as environmental science, soil science, biological science and other related disciplines, and belongs to the field, only a subject is difficult to obtain satisfactory results. Therefore, in the field of scientific research, we shouldstrengthen exchanges and cooperation among different disciplines and jointly establish a scientific and secure food strategy system in china. "Nurturing healthy land, producing healthy plants and animals, and providing safe food for mankind" requires screening and assembling traditional agricultural techniques and modern agricultural techniques. The establishment of different types of production demonstration bases and carry out different levels and different types of knowledge and technical training is necessary, which is also an important factor in food safety production in China can expand the scale and improve the level of three yuan, the Beijing dairy industry recently found no melamine from melamine tainted milk powder, the main reason in the tens of thousands of enterprises to establish a head dairy demonstration base.4, the establishment of market access systemIn China, Beijing, Guangdong, Zhejiang and other places have established a number of nationwide large-scale safe food wholesale market, all the goods required by the Department of quality and Technical Supervision Inspection qualified rear can enter sales, and the implementation of food safety market access system, do not meet the safety requirements of the green food restrictions on market access. Guangdong province has more than for food market access system, and will be fully implemented in the province of large and medium-sized city, all listed food must have a legitimate "identity card" can be listed for sale.Reference：1, our country food safety present situation and countermeasure, Aman Chang2, talk about the current situation of food safety in our country, He Wenjuan3.
