Question

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 (物種).
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.
【小題1】When was the plan to explore space first announced according to the passage?

A．In 1972.

B．In 1950.

C．In 1968.

D．In 2020.

解析試題分析：本文敘述了美國(guó)對(duì)于太空探險(xiǎn)的計(jì)劃，一是為了保護(hù)地球，二是完成美國(guó)的火星使命。三是更進(jìn)一步探險(xiǎn)太空。讓地球可以成為人們居住的地方。
【小題1】細(xì)節(jié)理解題。根據(jù)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.第一次宣布時(shí)的時(shí)間是1968年，故選C。
【小題2】細(xì)節(jié)理解題。根據(jù)announcing great plans for a base for humans to live on the surface of the moon forever.和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.只有選項(xiàng)D沒(méi)有提到，故選D。
【小題3】細(xì)節(jié)理解題。根據(jù)teams of astronauts living there for six months at a time would mine for hydrogen and oxygen to make water and possibly rocket fuel.故選D。
【小題4】主旨大意題。根據(jù)本文主要談?wù)摰氖敲绹?guó)對(duì)于太空探險(xiǎn)是計(jì)劃，故選A。
考點(diǎn)：科普類短文閱讀。
點(diǎn)評(píng)：做此類題目時(shí)，首先要搞清是問(wèn)某一段還是全文的大意，可利用文中主要信息來(lái)把握文脈，進(jìn)行綜合歸納，概括文章的主題。如有標(biāo)題，標(biāo)題中的蘊(yùn)含的信息往往是關(guān)鍵信息。另外，任何一篇文章都是圍繞某個(gè)主題展開的，因此，許多文章中最明顯的特點(diǎn)之一是有一個(gè)反復(fù)出現(xiàn)的中心詞，即高頻詞，也叫做主題詞。抓住了它，便容易抓住文章的中心。
