2022 P=HT 6. 次のお知らせを読み、 (1) ~ (2) のA~Dで適切なものに○をつけなさい。 [4×2=8] TO: All staff From: Erin Liner, Manager Date: July 15 Subject: Our survey Dear all. We have finished reviewing the data which we received from the recent customer satisfaction survey. I would like to share the most important findings, and how we can improve on certain areas of our work. Overall, customers were happy with the quality of our service. the helpfulness of our staff, and the range of products we offer. However, there were some negative comments which we can begin to work on. A common complaint was that there are not enough foreign titles in the store, especially Japanese comics. I will ask John Calman to research some of the most popular series and make sure we start carrying them from the fall. As Gita Pradesh spent her college years in Tokyo, I will ask her to assist. Better signage was another thing which people wanted. They spend a lot of time looking for the right section and it frustrates a lot of customers. This is something we can improve immediately, so I will speak to Alice Moore today about making the signs easier to see, and adding more if necessary. Finally, we got some comments about having a small cafe in the store. Nowadays, people want to have a coffee while reading or browsing, and it could be a new source of profit. Mario Venetti will make a report on the feasibility and deliver it next month. Thank you for all your efforts in making us the best we can be. Erin Liner Manager (1) What is the purpose of the e-mail? (A) To ask staff to create survey questions (B) To share details of customer feedback (C) To inform staff of recent changes (D) To invite staff to apply for new positions (2) Where does Ms. Liner most likely work?

From: To: Date: Subject: Dear Mr. Westbrook, Elaine McGee <E_McGee@kingsley.co.uk> Nicolas Westbrook <nic_westbrook@heymail.com> June 25 Fashion columns ((1X2) = 4 points × 2, (3) = 5 points) Hello. I'm the editor of Kingsley Press. I'm writing to ask you to write a column for our publication “SUNNY," a monthly magazine which has been providing useful information for middle-aged men so that they can lead their lives cheerfully and actively. I have read your fashion blog, and liked the pictures and descriptions., Each article was very understandable and told me you have good taste. Also, I was impressed with your extensive knowledge of art. Currently, there are a lot of middle-aged men who can't decide what to wear or are not good at shopping for clothing. If you wrote a fashion advice column, it would probably be a great help to our readers. We are planning a column series titled "Brush up your fashion now." I would like you to write a one-page column of about 400 words with a picture of coordinates monthly. I am offering you $100 per article, but I would like to discuss this and other details with you later. If your columns are popular, we will ask you to write other columns about art or movies. Please contact me if you are interested. Sincerely yours, Elaine McGee Kingsley Press

次の英文を読んで、設問に答えなさい。 Everybody wants to eat delicious and safe food. However, exposure to different cultures reveals 2 how people's attitudes towards food safety and taste are not all innate or biological. Assumptions and practices regarding the preparation and presentation of food highlight the influence of culture on what and how people eat. For example, in one culture, some kinds of fresh ingredients might be considered edible (a), that is, without any kind of preparation like washing, peeling or heating. Yet in another culture, the same foodstuff may require some kind of preparation before it can be eaten. It is often difficult for people from the same culture to view such activities and beliefs objectively, and so witnessing the food practices of other cultures can be surprising. Sashimi is a great example of this. While sashimi may be the result of several steps of preparation from cleaning and cutting, to a particular style of presentation - heating is not one of these steps. (2)Japanese consumers take it for granted Cultures, the conventional belief may be that real and fish require some sort of cooking, such as baking or frying, (3) in order (b) them to be considered edible. In these cultures, sashimi is not thought of as raw, delicious and safe to eat, but rather as uncooked, and therefore possibly unsafe to eat, regardless of how it may taste. Fresh chicken eggs are another raw foodstuff commonly eaten in Japan — as a topping for rice, or as a dipping sauce for sukiyaki, for example but most people in the UK or the USA believe that chicken eggs require some kind of heating before they are fit for human consumption. However, the ways in which people from other cultural backgrounds eat certain foods might be considered equally unconventional by many Japanese. For example, few Japanese would eat the skin of apples or grapes. In this case, the difference involved in the preparation of the food is not the use of heat, but the removal of part of the foodstuff. People in much of the world eat apples and grapes without peeling them. A European might think, What could be more healthy and delicious than picking an apple from the tree and eating it?' But this way of thinking is not shared by a large number of Japanese. (4) It is clear that different cultures have different conventions regarding the preparation of particular foods, and different beliefs about what is considered delicious. However, there is no question that some common food preparation practices - or sometimes a lack of certain food preparation processes - are unsafe from a scientific point of view. However delicious they may be, raw meat and fish can contain the eggs of harmful parasites like tapeworms, which are often undetectable. If chicken eggs are not properly stored, and are left unconsumed for a long time, they can easily produce bacteria like salmonella. The poisoning caused by salmonella does not usually require hospitalization, but it can be very dangerous for young children and elderly people. In addition, while eating the skin of apples and grapes may be a good source of dietary fiber, one also runs the risk of consuming insecticides, the poisons that are used to protect many non-organically farmed fruits from insects. So, while there may be 'no accounting for taste' beyond culture, safety is a different issue, and (5) we should always be aware of the risks involved with culturally accepted methods of food production and consumption. 問1 下線部 (1)で,空欄 ( a )に入る最も適切な語句を, (A)~(D)から選び, 記号で答えなさい。 (A) as is clear (B) as is fresh (C) as they are (D) as unclean 問2 問3 問4 問5 下線部(2)を日本語に訳しなさい。 下線部 (3)の空欄(b)に入る語(1語) を書きなさい。 下線部(4) を日本語に訳しなさい。 下線部 (5)の理由として最も適切なものを, (A)~(D) から選び,記号で答えなさい。 (A) Eating raw chicken eggs or unpeeled fruits can be dangerous in certain conditions because of harmful bacteria or pesticides. (B) Eating unpeeled apples or grapes may cause weight gain. (C) Only young children and elderly people are vulnerable to particular bacteria. (D) Beliefs about what is considered delicious actually come from better understanding of food preparation. 問6 本文の内容と一致するものを, (A)~(G)から3つ選び,記号で答えなさい。 (A) By food preparation processes, the author exclusively means the use of heat. (B) Culturally established ways of consuming food may conflict with scientific principles of food safety. (C) In some food cultures outside Japan, fish in its raw state is not categorized as an edible foodstuff. (D) People having little contact with other cultures tend to view their own food-related conventions as natural and standard. (E) Repeated exercise is required for the mastery of any food preparation. (F) Instinct alone determines what and how people eat. (G) All cultures around the world consider it natural to eat unpeeled fruit.
