Live Earth is pleased to announce the largest worldwide water initiative(倡议)in history to help fight the global water crisis. The Dow Live Earth Run for Water—to take place on April 18, 2010—will consist of a series of 6 km run/walks (the average distance many women and children walk every day to get water) taking place over the course of 24 hours in countries around the world, featuring concerts and water education activities, raising awareness and funds to help solve the water crisis. Jessica Biel, Alexandra Cousteau, Pete Wentz, Angelique Kidjo and Jenny Fletcher will lend their names and their time in support of this global event.
Water shortage is a major issue affecting countries, communities and families all over the world. One in eight people doesn’t have access to safe, clean drinking water. Communities in Africa, Latin America and Asia suffer 1.8 million deaths every year from diarrheal(腹泻）diseases and the death of 5,000 children each day due to inadequate water infrastructure(基础设施). In these areas, women and children are forced to walk 6 km (3.7 miles) each day to get water that is likely unsuitable for drinking. However, the water crisis is not only limited to developing nations. Adding to these existing issues, the effects of climate change are increasingly impacting both supply and quality of available fresh water throughout the world.
In 60% of European cities with populations greater than 100,000, groundwater is being used faster than it can be replenished(补充). By 2025, two-thirds of the world’s population could be living under water-stressed conditions.
You can help solve the water crisis by participating in the April 18th event. Run/walk registration is now officially open! Sign up now at http://liveearth.org/run.

Stephen Hawking believes that the earth is unlikely to be the only planet _______ life has developed gradually.

One morning I wasted nearly an hour watching a tiny ant carry a huge feather. Several times, it   31   several obstacles in its path. And after a momentary pause it would make the necessary detour (绕道).   32  one point, the ant had to cross a crack about 10mm wide. After some   33
thoughts, the ant laid the feather over the crack, walked   34  it and picked the feather up on the other side, then continued on its way. I was   35  by the cleverness of this ant. It was only a small insect, lacking in   36  yet equipped with a brain to reason, explore, discover and overcome. 37  this ant, like the other two-legged creatures   38  on the earth, also shares human failings.
After some time the ant   39  reached its destination—a flower bed and a small hole that was the entrance to its   40  home. It was there that the ant met its   41 .How could that large feather possibly   42  such a small hole? Of course, it couldn’t. So the ant, after all this   43  and using great brightness, overcoming problems all along the way, just gave up the   44  and went home. The ant had not thought the problem through   45  it began its journey and in the end the feather was   46  more than a burden. Isn’t our   47  like that?
We worry about our families; we worry about the   48  of money; and we worry about all kinds of things. These are all burdens—the things we pick up along life’s path, and drag them around the obstacles and over the cracks that life will bring, only to   49  that at the destination they are
50  and we can’t take them with us.

Air is an odorless(that cannot be smelled;smelless),invisible(that cannot be seen)gas that surrounds the planet earth.It is everywhere on the planet.An “empty” drinking glass and an “empty” room,to give two examples,are not really empty.Each is filled with air.When the glass is filled with water,the water pushes the air out of the glass.
Air,as a gas,has no definite(fixed,particular)shape,but,because it is matter,it takes up space.It is easy to prove that air is something that takes up space.Stuff a dry handkerchief into the bottom of a glass so that it will not fall out when the glass is turned upside-down.Push the upside-down glass,hold it straight into a jar of water till the glass is completely covered.When the glass is taken out of water,the handkerchief will be dry.The air inside the glass took up space and kept the water from coming in.
1.“Stuff a dry handkerchief into…”.The underlined word means.
A.Press tightly B.Take out C.Put down D.Turn fully
2.The writer tells us that _________.
