          5. Blast

          俚語,指“令人極興奮或愉快的經歷、事件或熱鬧聚會”。

          6. Out of someone's hair

          首先來說說這個片語的反義詞:in someone's hair,想想看,如果有東西在你的頭發里,你是什么感覺?In one’s hair 的意思就是“annoying or bothering someone 煩擾某人”,例如:She was constantly in my hair, overseeing everything I did.

          那么,out of one’s hair 就是叫“別人不要煩你”了。如果有人煩你,你就可以這么說:Get out of my hair!

          7. Miss out

          Miss out 指“錯失機會”,例如:She always misses out, because she's never there.

          這個片語常和on連用,表示“錯過了……”例如:Ruth came late to the party and missed out on all the fun.

          Apollo Lunar Module 阿波羅登月艙

           Apollo LM on lunar surface

          The Apollo Lunar Module was the lander portion of the Apollo spacecraft built for the US Apollo program to achieve the transit from moon orbit to the surface and back. The module was also known as the LM from the manufacturer designation (yet pronounced "LEM" from NASA's early name for it, Lunar Excursion Module).

          The 6.65 m3 module was designed to carry a crew of two. The total module was 6.4 m high and 4.3 m across, resting on four legs. It consisted of two stages — the descent stage module and the ascent stage. The total mass of the module was 15,264 kg with the majority of that (10,334 kg) in the descent stage.

          The Apollo Lunar Module came into being because NASA chose to reach the moon via a lunar orbit rendezvous (LOR) instead of a direct ascent or Earth orbit rendezvous (EOR). Both a direct ascent and an EOR would have involved the entire Apollo spacecraft landing on the moon; once the decision had been made to proceed using LOR, it became necessary to produce a separate craft capable of reaching the lunar surface.

          The LM contract was given to Grumman Aircraft Engineering and a number of subcontractors. Grumman had begun lunar orbit rendezvous studies in late 1950s and again in 1962. In July 1962 eleven firms were invited to submit proposals for the LM. Nine did so in September, and Grumman was awarded the contract that same month. The contract cost was expected to be around $350 million. There were initially four major subcontractors — Bell Aerosystems (ascent engine), Hamilton Standard (environmental control systems), Marquardt (reaction control system) and Rocketdyne (descent engine).

          The primary guidance, navigation and control system (PGNCS基本導航、飛行與控制系統) on the LM was developed by the MIT Instrumentation Laboratory (麻省理工學院儀表實驗室). The Apollo Guidance Computer (導航計算機) was manufactured by Raytheon (雷神公司). A similar guidance system was used in the Command Module. A backup navigation tool, the Abort Guidance System (AGS (航天器初級引導系統出故障時啟用的)中斷飛行引導系統), was developed by TRW (Thompson Ramo Wooldrige Inc).
