  Read these two advertisements, and then answer the questions.

  When you stretch out in the sun you can do one of three things.

  You can use no sun tan oil. You can use an ordinary sun tan oil. Or you can use Bergasol.

  If you don't use any sun tan oil at all when you're in sun that is stronger than you're used to, you will burn surprisingly quickly.

  If you use an ordinary sun tan oil you will protect your skin to a lesser or greater degree. How much depends on the“protection factor(系数)number”on the bottle.

  Some of these oils block out so many of the sun's rays you can stay in the sun all day without burning--but you won't go very brown, either.

  Bergasol will protect your skin like an ordinary sun tan oil. But Bergasol oil also has a tan accelerator(加速剂) which comes from the oil of the Bergamot fruit.

  It speeds up the rate at which the sun activates(激活) the skin cells that produce melanin.

  And it is melanin which gives the skin its brown colour.

  So when you use Bergasol sun tan oil you go brown faster, and as the days pass the difference will become more and more obvious.

  Unfortunately this special formulation isn't cheap to prepare. So Bergasol is rather more expensive than ordinary sun tan oil.

  However the price looks more attractive as you do.

  Protection

  Many people imagine that“cover-up”means you don't get a tan. Nothing to show for your holiday. What a shame.

  Not so. With“cover up”, you can get brown if you want to. The point of cover-up is to protect your skin from the harmful rays of the sun--the ones which, according to the experts, make your skin look older.

  That's what Solex Cover-up is all about--protection for your skin. It has a Sun Protection Factor of 8, which makes it suitable for anyone.

  Find 0ut how it works for you by consulting(咨询)the Solex Sun Chart. On sale wherever Solex is.

  With Solex Cover-up, you can tan as slowly as you like. As gently as you like. And with much less chance of peeling.

  Your tan will look better. Your skin will stay young longer. Solex Cover-up.

  Gentle tan…full protection.

  War, money and power are a few things that countries and people are concerned about.  1  I agree that those things are important, I believe that everyone should start to  2  more on a growing problem-global warming.

  Global warming will not only  3  our country and our generation, but also the entire  4  and future generations.It is  5  because the weather has been a lot warmer over the past few years, which  6  the melting(融化)of the ice in the Antarctic.This will soon cause water levels to  7  and flood parts of the world.

  Many people ignore this problem because they feel  8   they can't do anything about it and have more  9  things to worry about.If we all  10  so, then our ozone layer(臭氧层)will be  11  and the planet will no longer be able to make life continue to exist.We should do our best to limit the use of our planet's  12  resources(资源)and keep our air clean.  13  , future generations will suffer from our  14  

  Some might feel that they can't stop global warming from  15  .But if every single person does his or her part in keeping the air clean, then it will become a  16  effort.Sure, there are some things that cause pollution and that we won't be able to  17  change.This may include cars burning oil, but we can  18  adjust some of these things.People can start carpooling, taking the bus, riding their bikes, or  19  just walking.

  If everyone takes  20  now, I believe we can start seeing remarkable results within a few years.
