[2] Life is fragile, precious, and unpredictable, and each day is a gift, / not a given right. I'm 27 years old now. I love my life and I am happy. I don't want to leave the world, / but that decision is out of my hands. [3] I'm not writing “A Note Before I Die" / so that people will fear death. In fact, it's good/ that we are not constantly thinking / about its inevitability. For the most part, / death is often considered a "taboo" topic, / especially among young people. I want people to remember/ that we all suffer the same fate / in the end. So, stop worrying / about the little issues/ that cause meaningless stress / in everyday life. Whenever you start complaining / about unimportant things,/think about those people / who are actually facing serious problems / and be grateful/ that your problems are minor ones. Take a deep breath of the fresh air, / and be thankful/that you are able to breathe it in. 1. H OP 訳 2. 22 訳 3. 33 activity B 各段落のトピック

下線部(1)の文構造が分かりません。特に2行目の文構造が分かりません。強調のdoであることは分かりますが、その後のthat以降が関係詞?かすらも分からないので、誰か教えて下さい!

次の英文は1991年に出版された本からのもので、 研究分野としての「人工知 能」 (Artificial Intelligence) について述べています。 下線部(1)~(3)を日本語に訳 しなさい。 What is Artificial Intelligence (AI)? Just about the only characterization of Al that would meet with universal acceptance is that it involves trying to make machines do tasks which are normally seen as requiring intelligence. There are countless refinements of this characterization: what sort of machines we want to consider; how we decide what tasks require intelligence and so on. One of the most important questions concerns the reasons why we want to make machines do such tasks. AI has always been split between people who want to make machines do tasks that require intelligence because they want more useful machines, and people who want to do it because they see it as a way of exploring how humans do such tasks. We will call the two approaches the engineering approach and the cognitive-science respectively. (2) (1) approach The techniques required for the two approaches are not always very different. For many of the tasks that engineering AI wants solutions to, the only systems we know about that can perform them are humans), so that, at least initially, the obvious way to design solutions is to try to mimic what we know about humans. For many of the tasks that cognitive-science Al wants solutions to, the evidence on how humans do them is too hard to interpret to enable us to construct computational models, so the only approach is to try to design solutions from scratch" and then see how well they fit what we know about humans. The main visible difference between the two approaches is in (3) their criteria for success; an engineer would be delighted to have create something that outperformed a person; a cognitive scientist would regard it as a failure. -1- M7 (492-61
