题目：

一幢高60m、按6度抗震设防、位于Ⅳ类场地的钢筋混凝土框架一剪力墙结构的市级电信大楼，经计算可知：在基本振型地震作用下，框架部分承受的地震倾覆力矩大于结构总地震倾覆力矩的50%。在进行结构的抗震设计时，下列各项正确的是( )。

A．因6度抗震设防，可允许不进行截面的抗震验算，仅需对框架和剪力墙分别按四级和三级抗震等级考虑抗震构造措施

B．应进行截面的抗震验算，并同时对框架按四级、剪力墙按三级抗震等级考虑抗震构造措施

C．应进行截面的抗震验算，并同时对框架按三级、剪力墙按二级抗震等级考虑抗震构造措施

D．应进行截面的抗震验算，并同时对框架和剪力墙均按二级抗震等级考虑抗震构造措施

     How to beat sadness We all have days when we are down, tired and unhappy. That's OK. You need days
like this, or how would you know you are happy? You'll enjoy your good days even more when you have a
few bad days. Even if sadness is a part of life, let's try to make it small. Here are a few simple ways to help
you feel better when you are feeling sad.
     1. Stand up straight and this helps your energy flow (流动). When your energy is flowing freely, you can
flow too.
     2. Smile! It's easy to do and have good results. This way can not only leave you in a good mood but also
bring others a good mood.
     3. Listen to music. It can be your favourite music. Some kinds of music work better than others, so try
and find out what kind of music works the best for you.
    4. Take some "me" time. You can find pleasure in reading a book, watching a sunrise or having a hot bath,
or something like that.
    5. Exercise. Even something as simple as taking a walk will get your blood flowing. It is a great way to
clear your mind of anything that makes you sad.
     These ways will cheer you up when you are down, but don't just use them when you are sad. Try and
practice them every day to make them a habit. You will be surprised to learn that these simple ways will keep
your sadness away. But if you are in a deep depression (沮丧), go to see a doctor.
