Question

【題目】 You can’t play, run, skate or ride a bike on the railroad ( 鐵 路 ). There are many places where the railroad tracks ( 軌道) cross the roads or streets. Many of these railroad crossings are marked with the signs in the table below.

	This sign means you are coming to a railroad crossing. Always look both sides and listen carefully to be sure a train is not coming from either direction before you go across the tracks.
	Many railroad crossings have a gate with flashing lights. The gate will close whena train is coming ● NEVER play around a closed railroad gate. ● NEVER try to get across the tracks before the train gets there.
	Some railroad crossings which don’t have gates may have this sign. When the lights are flashing, a train is coming. You should wait until the train passes instead of trying to cross the tracks.

Be careful when crossing road tracks:

* Railroad tracks are uneven (凹凸不平的). You should not bicycle, skate or run when crossing the tracks.

* Trains are very large and heavy, so they need take a long time to stop.

* Sometimes when a train has just passed from one direction, another train may come from the opposite direction. You may not notice the second train because of the noise of the first train.

【3】C

【解析】

本文主要是告訴我們鐵道路口的標志，告訴我們注意安全。

【1】細節(jié)理解題。根據(jù)“Always look both sides and listen carefully to be sure a train is not coming from either direction before you go across the tracks.”可知，第一個標志告訴我們過鐵道之前，一定要兩邊看，仔細聽，以確保過鐵道前沒有火車駛來。故選D。

【2】細節(jié)理解題。根據(jù)“Some railroad crossings which don’t have gates may have this sign.”可知，一些沒有大門的鐵路道口可能有這個標志。故選D。

【3】推理判斷題。A項：鐵路道口有許多門；B項：在我們的城市里可以看到許多鐵路標志；C項：在鐵路上玩、跑或騎自行車是危險的；D項：火車停下來需要很短的時間。分析全文內(nèi)容可知，主要是介紹鐵路標志，告訴我們要注意安全。故選C。
