Some years ago, we decided to keep manga in our library because they had become an important part of Japanese culture. We asked the librarian, ( a ) is an expert on choosing books, to select them. Manga are chosen based (b) the policy that they have something to do ( c ) school subjects such as history, science, or Japanese literature. Some manga that provide valuable life lessons are also selected. Therefore, I'm convinced that the manga in our library are valuable. You pointed out that your daughter reads the same titles repeatedly. According (d) the librarian, good manga and books often give a student different perspectives upon each reading. 7) If your daughter is absorbed in the same manga, she is learning, which is actually very Morinen) u valuable. 1 ) Try to limit your daughter's manga reading to one hour per day. Also, the next time you come to school, please visit the library and look through some manga. They may give you a new perspective. Sincerely yours, Dr. Charles Pepper QQ(a)に入る適切な関係詞を書きなさい。 2.

3 次の英文は, 中学生の花子 (Hanako) が行ったスピーチである。 これを読んで、 問い (1) ~ (9) に答えよ。 (24,5) There are some people cleaning streets in my town every morning. Also, there are some *crows looking for something in the trash. Many kinds of trash are *scattered around the *dump by them. That is a problem of trash and crows. Many people don't want to *fight with crows, but they want to solve the problem. IA J There is one way to solve the problem. I often see yellow plastic bags for trash. I heard that crows 2[(7) put (1) see (5) the yellow / (I) in / () cannot / () the things] bags. If crows think that there isn't any trash in them, they will go to another place, and we don't have to fight with crows. [B] *However, many crows still come to dumps in my town. They learn quickly and understand well, and they know where to find something for their lives. So, they come back to look for it in trash if they think they can do that easily. What are they trying to find in our trash? If I can answer this question, I may find a better way to solve the problem of trash and crows. So, I started learning about crows. My uncle is studying about crows. He often watches crows in some places and tries to understand their lives. He 3 (tell) me about it last week. They get up very early in the morning and usually start looking for their food in the trash of some restaurants or food shops. In such trash, crows can find their favorite food like *French fries or *mayonnaise. My uncle said that they like *oily food. I thought it's interesting because I like the same food. [ C] Also, they want to find something for making their houses. For example, they need *soft things like dog hair or "cotton because they want to put their eggs on such things. I was surprised to learn that crows find these things very well. There are some better ideas to solve the problem of trash and crows, my uncle said. First, people should put a big *net over the trash. When there is a net, it is difficult for crows to scatter trash around a dump. Heavy nets with small mesh are better. Second, when people put their trash in the dump, they should be careful about the time. Usually, the trash is 4(collect) in the morning. Crows may come and scatter it before that if you put the trash in the dump the previous night. 【D If it is difficult for crows to get their food in our town, they will move to another place. 5My uncle knows what we can do to solve the problem of trash and crows because he always tries to understand them. I think he can see the problem from the side of the crows. 6 We don't want to fight with crows, but ? I've heard that the crows sometimes hit people. Do they want to fight with us? That may not be true. My uncle said that the crows are trying different ways to say, "Don't come around our house!" They want to protect their children when someone comes around their house. Crows are large birds and they can fly, so they look strong. However, they are afraid if someone is near them and they don't usually want to fight with us. So, they don't come around the trash when someone is there. I learned about crows and I understood them better than before. They are just trying very hard to get. things for their lives, and they can find them in our trash easily. So, I don't think they are bad. Scattering trash is a problem to us. However, if I see this problem from the side of the crows, then I will know what I can do to solve it. For example, I will not make much food trash, especially oily food trash, and I can be careful about my way of putting the trash in the dump. There is not an easy way to solve the problem of trash and crows, but now, I know it is important to think about it from the side of the crows. We often think about a problem only from our own side, but if we look at it from another side, we may find a better idea.

This method, however, has produced a lot of debate. Many think it is wrong to treat live eggs as objects and then “kill them, even though the purpose is to treat patients. In addition people fear that this method could lead to human cloning. 5 For years, Dr. Yamanaka and his research team worked hard to find a different way to create tissue. Then, in 2007. they finally succeeded in creating heart muscle tissue from skin cells taken from a person's face. They first added four kinds of genes to the skin cells to put them back into their initial state, a state similar to egg cells. Then they made those cells grow into heart muscle tissue. The four genes they found are now called "Yamanaka Factors," and the initialized cells that can grow into any of the 200 cell types are called iPS cells. ma 20 on 18 th r 25時
