NASA has opened the door to the next generation of space discovery by announcing great plans for a base for humans to live on the surface of the moon forever.
The project to build a base on the moon will begin soon after 2020, with astronauts living there within four years.
The project comes after several excellent scientists and environmentalists asked humans to look beyond Earth to ensure the survival of the species (物种).
Eventually, the moon will be a base for humans to explore the solar system and one day land on Mars.
NASA began planning for the first moon landing since 1972 when George Bush, the US president, announced his new plan for space exploration four years ago.
NASA has already talked about the design of the Orion spacecraft that will replace the old space shuttle fleet in 2010.
The plan for the moon base, however, is the first detailed explanation of how NASA intends to prepare for the first manned exploration of deep space and a possible Mars mission within 30 years.
Scientists also believe that the south pole on the moon contain rich natural gases such as the rare helium-3 that could be used as fuel for the generation of nuclear power. Besides, teams of astronauts living there for six months at a time would mine for hydrogen and oxygen to make water and possibly rocket fuel.
1.The reasons why NASA has begun the plan to explore space include the followings except ________.
A. to protect Earth
B. to explore deep space
C. to finish Mars mission
D. to show how powerful the USA is
2.In the future, when people fly to the moon, they will probably not bring with them too much ________
A. hydrogen B. food C. oxygen D. water
3.The passage mainly talks about ________.
A. the USA’s new plan for space exploration
B. how to build a base on the moon
C. why to ensure the survival of the species
D. where to get new natural resources

How to Do basic first Aid
Basic first aid refers to a temporary form of help given to someone who has been injured or has got sick due to choking, a heart attack, drugs or other medical emergencies. 1..
Care for the person who has just gone through serious damage, including both physical treatment and emotional support. 2.. Let the person know that help is on its way and that everything will be all right. Also you can ask for their names, if they know what has happened, and then about their interests.
3.. You’d better listen for the sound of air coming in and out, and feel for air using the side of your face. If there are no signs of breathing, place two fingers under the chin (下巴) and gently guide the face pointing upwards to open up their airways.
Perform 30 chest compressions (心肺复苏) and two rescue breaths as part of CPR. 4.. And then press the chest down about 2 inches at a rate of 100 compressions per minute. After 30 compressions, give two rescue breaths, done by opening the airways, closing the nose and fully covering the mouth hole.
Make sure the person is warm as you wait for medical help. Remove some of your own clothing, such as your coat or jacket, and use it as a cover until medical help arrives. However, if the person has a heatstroke (中暑), do not cover him or keep him warm. 5.

D.Here are some tips for first aid
