What can be inferred from Reynolds’ words？（　　） A. Researchers are determined to face the challenge. B. The research is very difficult to conduct. C. Finding a similar group is easy. D. Astronauts are not as healthy as athletes. 解析：　推理判断题。根据最后一段中Reynolds说的话可知，如 果这些宇航员当初没有去太空，而是被雇用做了其他工作，那么他 们的健康状况是否与现在相同。要想完成这项研究，则需要找到在 这几个重要因素上具有对照性的群体。由此推断，这项研究很难进 行下去。 目录 英语·必修第三册 8. What can be a suitable title for the text？（　　） A. Astronauts — Healthy or Otherwise B. Astronauts Are as Healthy as Athletes C. Radiation Affects Astronauts’ Health D. Astronauts — Be Well Educated and Earn More 解析：　标题归纳题。通读全文可知，本文主要介绍了一项研 究，该研究表明，太空辐射不会缩短宇航员的寿命，但其健康状况 是否会受到影响仍然是未知的。因此A项（宇航员——健康与否） 适合作本文的标题。 目录 英语·必修第三册 Ⅱ.阅读七选五 　　Over the years， we have discovered that our students seem to have more success with some methods of learning new words than with others.We’ll show you the methods we have found to be the most successful for our students.9.（　　） 　　Basic Method 1：Seeing Is Remembering 　　Letting a new word suggest a vivid mental image to you is a powerful and effective way to remember that word.Mental images are really mnemonics （记忆术）， too.They help you remember.10.（　　） When it comes to mental images， crazy is better than normal.Normal is boring.Crazy is dramatic. 目录 英语·必修第三册 　　Basic Method 2：Etymological （词源的） Clues 　　Although the English language contains hundreds of thousands of words， you will discover that many groups of words are related in meaning.11.（　　） When you recognise that a group of words shares a similar root， you will more easily remember the entire group. 　　Basic Method 3：Writing on Your Brain 　　Many people find that they can learn new information more readily if they write it down.12.（　　） Perhaps the explanation is that by writing you are bringing another sense into play — you’ve seen the word， you’ve said and heard the word， and now you’re feeling the word. 目录 英语·必修第三册 　　Basic Method 4：Putting It All Together with Flash Cards and a Notebook 　　A flash card is a simple piece of paper or cardboard with a word on one side and a definition on the other.You may have used flash cards when you were first learning to read， or when you were first tackling a foreign language.13.（　　） You should also indicate the pronunciation if you aren’t sure you’ll remember it. A. Use the one or ones that suit you best. B. You don’t have to write each word on a card. 目录 英语·必修第三册 C. The emphasis here is on suggestive mental pictures. D. Why？ Because they developed from a common root. E. Many students find it hard to remember long English words. F. The physical act of writing seems to plant the information more firmly. G.
