② 次の英文を読んで,下の各問いに答えなさい。 It is a well-known fact that most Japanese students cannot converse (1) English. This is sometimes because they have nothing to say and are poor conversationalists even in Japanese: in order to talk, one must usually have something to talk about! But often their lack of fluency in English is the result of a kind of false modesty: they are unwilling to "show off" their knowledge of English in front 5 (3) other Japanese. Or they simply fear to make mistakes, and this fear prevents them (4) expressing themselves fluently. It is a fear frequently expressed in the unnecessary apology: "Please excuse my bad English" or "I wish I could speak better English." Also, when I am with a group of Japanese students for the first time - perhaps we have met casually on the street or on a train-and one boy in the group starts trying to speak to me in English, his brave efforts are nearly always met 10 with laughter from his friends who probably know less English than he does.

25 20 1 5 15 The two men quit their jobs and decided to create a trash bin for the ocean, which they called a "seabin." They made the first model of the seabin and raised money to start the Seabin Project. The project's aim was to distribute a lot of seabins around the world. The seabins were designed to automatically collect trash 6972 自動で 10 from the surface of the ocean by using a bump powered by electricity. By へを源動力と した 電気 collecting trash near marinas and harbors, they hoped to stop the trash from Wastebasket in the Sea The increasing amount of trash in the ocean is a big global issue nowadays. It is 海のゴミの difficult to collect plastic bottles, plastic bags, cans and oil drifting on the waves. It would take a lot of time and effort. However, in Australia, two surfers named Pete Ceglinski and Andrew Turton never gave up hope. They had always loved the 昔からすきだった。 ocean and wanted to keep it clean. flowing further into the ocean. 流れる さらに良く インストール Re97-H1L F Seabins are very simple to use. A seabin is installed several centimeters below the surface of the water. When the pump is turned on, water flows into the seabin with trash on the surface. Then the water passes through a catch bag inside the 通り抜ける bin. The water is pumped back into the sea, leaving the trash inside the catch bag. Seabins are able to collect plastic that is as small as two millimeters. The catch bag can hold up to 20 kilograms. The amount of trash collected varies depending on 2MKI chŢint gk 6.10 the weather, but the estimated average amount per day is about 1.5 kilograms. THEAU 平均 A pad to absorb oil, detergent and microfibers can also be attached to the M とりつけてる seabin. Improvements like this continue to be made. The project team is also trying to educate people. For example, the team is teaching children what they can do to reduce the amount of trash in the ocean so that they can influence other members of their family and their friends. The goal of the Seabin Project is to make the ocean clean so that these seabins will no longer be needed. Ceglinski and Turton hope to pass on a clean ocean to future generations.
