【1】 次の英文を読んで, 下の各設問に答えなさい。 These days, many people say that *agriculture is very important. We have( ① ) many kinds of things, such as rice, fruits and vegetables for a long time. Through agriculture, a lot of foods are produced, so we are able to have food every day. Agriculture is necessary for our lives in many ways. の In Japan today, more and more people are thinking about agriculture. People want to get safe food for their health. Some people ask, “Where do these carrots come from?” or “Do the farmers use *agricultural chemicals?” So, many people like to buy fruits and vegetables produced near their homes.It is called chisanchisyo in Japanese. In the United States, they have the *movement called *Community Supported Agriculture (CSA).. People give some money to the farmers( 3) in their *local area. They can get fruits or vegetables from the farmers *instead of going to the stores. In other words, *consumers support the farmers in their own community. 4) Chisanchisyo and CSA have good points for both consumers and farmers, For consumers, frst, they can know where the fruits and vegetables were produced. Second, those products are fresh and taste delicious because ⑤ thev [farms/ are/ in/ stores / carried / to/ from」 a short time.*In addition, consumers can choose the farmers who don't use agricultural chemicals.

Farmers are careful about the safety of food: Agricutural chemicals are used to *protect firuits and vegetables from *insect pests, but (O) too much chemicals is sometimes bad for people. So, some farmers are trying to produce fruits and vegetables( agricultural chemicals. Instead of agricultural chemicals, they use sonme kinds of insects and special plants. For example, some farmers use *ladybugs. They like to eat *plant lice. Plant lice are insect pests of vegetables. Iffarmers do not take action, 'many vegetables will be eaten by them. So the farmers hope that ladybugs will eat many plant lice. *companion-plants. They are plants which help to reduce insect pests and make vegetables better. Green onion is one plant that reduces plant lice on tomatoes. Plant lice don't like the strong smell of green onion, so farmers protect vegetables by planting them near tomatoes. As a result, farmers don't need to use any agricultural chemicals. Farmers are trying to produce vegetables which don't use agricultural chemicals. To get safe and healthy foods, consunmers and farmers need to help each other. Also, we are nowthinking about using not only natural ways but also new technology such as robots. Other farmers use
