英語六級(jí)攻克閱讀關(guān)鍵句225. The satellite signals, along with inputs

225. The satellite signals, along with inputs on speed from a wheel-speed sensor and direction from a meter, determine the car's position even as it moves.

譯文　衛(wèi)星信號(hào)與傳感器指示的輪速和儀表指示的方向一并決定了汽車的位置，甚至在汽車行進(jìn)中也是如此。

點(diǎn)睛　本句的主干是The satellite signals...determine the car's position...。along with 引導(dǎo)伴隨狀語，as引導(dǎo)時(shí)間狀語從句。

input意為“輸入；輸入信息”。sensor的意思是“傳感器；探測(cè)器”。meter在此處意為“儀表”。

考點(diǎn)歸納　position、location和scene都含“地點(diǎn)、位置、場(chǎng)所”之意。它們的區(qū)別在于：

position多指某物體相對(duì)于其他物體所處的位置或狀態(tài)。如：

From his position on the cliff top, he had a good view of the harbour. 他在懸崖之巔，海港景色一覽無余。

location指某物設(shè)置的方向或地點(diǎn)。如：

What's the exact location of the ship? 那條船的確切位置在哪里？

scene常指真實(shí)事件或虛構(gòu)故事發(fā)生的地點(diǎn)。如：

Firefighters were on the scene immediately. 消防隊(duì)立刻趕到現(xiàn)場(chǎng)。
