     -- ________  your homework yet?

    -- Not yet. I _______ it.

    A. Have you done; am doing                          B. Did you do; am doing

    C. Have you done; did                                     D. Did you do; did

     

    【答案】

    A               

    【解析】             

    试题分析：考查动词时态。句意 你做完作业了吗？没有，我正在做。haven't done 强调还没有做这个概念， 而 am doing 是说马上要做，口语中常说的（这时现在进行时表将来的概念，例如I'm coming. I'm going to school），所以选A项。

    考点：考查动词时态。

    The human brain weighs about 1.4 kilograms, but it can, hold much more information than most computers. However, there is another difference between humans and computers. Computers don't forget information they are given, but humans often do. No one remembers everything, and luckily we don't usually have to. But everyone can improve their memory if they want to. Here are some suggestions.

    ◆Try to use new informati6n immediately. For example, if you meet someone who says "Hi! I'm Carlos," don't just say "Hello." Repeat the person's name. Say"____"

    ◆Break a big number into smaller parts. For example, it's hard to memorize (记忆) 109244153. But if you break it into three parts--109/244/153—it becomes easier.

    ◆Write out what you need to remember ever and over again. This will help you keep it in mind longer, especially for memorizing formulas (公式) or facts.

    ◆Always review information. If you bring what you've learned back to your mind, they become easier to remember. For example, before you go to sleep, it’s a good idea to review the new things you learned that clay.

    ◆Discuss with a friend. It is always easier to remember things through discussions. You can have a discussion about what's right and what's wrong, and it will lead to the right answer.

    ◆Never tell yourself that you have a bad memory. You can always do something to help improve your memory. And everyone's memory gets better if they use it often enough.

    C. To discuss it with a friend.              D. To review it before you sleep.
