13．Wearing shoes _______ for the activity you are doing can help avoid some foot injuries to a large extent．（　　）
A．designB．designingC．designedD．to design

分析 穿专门为你所从事的活动而设计的鞋可以最大限度地避免一些脚的伤害．

解答 答案：C
句中design是作shoes的后置定语，要用非谓语动词；design和shoes构成动宾关系，要用表示被动的过去分词．故选C．

点评 过去分词是非谓语动词的一种，表示被动或完成；done过去分词的简单式，表示与谓语同时或几乎同时发生的动作；having been done过去分词的完成式，表示先与谓语的动作．学习时，要注意区分和掌握．

2．How many things can you see in the night sky？A lot!On a clear night you might see the Moon，some planets，and thousands of sparkling stars．
You can see even more with a telescope．You might see stars where before you only saw dark space．You might see that many stars look larger than others．You might see that some stars that look white are really red or blue．With bigger and bigger telescopes you can see more and more objects in the sky．And you can see those objects in more and more detail．
But scientists believe there are some things in the sky that we will never see．We won't see them with the biggest telescope in the world，on the clearest night of the year．
That's because they're invisible．They're the mysterious dead stars called black holes．
You might find it hard to imagine that stars die．After all，our Sun is a star．Year after year we see it up in the sky，burning brightly，giving us heat and light．The Sun certainly doesn't seem to be getting old or weak．But stars do burn out and die after billions of years．
As a star's gases burn，they give off light and heat．But when the gas runs out，the star stops burning and begins to die．
As the star cools，the outer layers of the star pull in toward the center．The star squashes into a smaller and smaller ball．If the star was very small，the star ends up as a cold，dark ball called a black dwarf．If the star was very big，it keeps squashing inward until it's packed together tighter than anything in the universe．
Imagine if the Earth were crushed until it was the size of a tiny marble．That's how tightly this dead star，a black hole，is packed．What pulls the star in toward its center with such power？It's the same force that pulls you down when you jump-the force called gravity．A black hole is so tightly packed that its gravity sucks in everything-even light．The light from a black hole can never come back to your eyes．That's why you see nothing but blackness．
So the next time you stare up at the night sky，remember：there's more in the sky than meets the eye!Scattered in the silent darkness are black holes-the great mystery of space．
