上海兩大機(jī)場將提高安檢級(jí)別至二級(jí)，相當(dāng)于之前北京奧運(yùn)會(huì)及上海世博會(huì)的水平。乘客被要求摘下戒指、項(xiàng)鏈，并從口袋里拿出硬幣，不然安檢系統(tǒng)可能會(huì)發(fā)出警報(bào)。二級(jí)安檢會(huì)占用每位旅客三分鐘左右的時(shí)間。

先看相關(guān)英語報(bào)道：
Shanghai's two airports are raising security checks to Level-2, or the same as those in place during World Expo 2010 and the Beijing Olympics.Passengers were advised to take off rings and necklaces and take coins from their pockets because alarm systems had been adjusted to be more sensitive, It takes about three minutes for each passenger to receive the stricter checks.

分析：
上述報(bào)導(dǎo)中的"security check"就是安檢的意思。安檢共分為三個(gè)級(jí)別：一級(jí)安檢（Level-1）中，所有旅客都要經(jīng)過嚴(yán)格安檢，進(jìn)行多次X光機(jī)掃描探測，隨身行李全要經(jīng)過機(jī)器和人工的雙重檢查，行李也要經(jīng)過爆炸物檢測器檢測。二級(jí)安檢（Level-2）中，不少乘客至少要經(jīng)過兩道X光機(jī)身體掃描，同時(shí)還要脫鞋、解皮帶等，接受手持探測儀的搜身深檢，乘客隨身物品要嚴(yán)格抽檢且不能少于50%。三級(jí)安檢（Level-3）為普通級(jí)別，就是眾多旅客日常在機(jī)場出行時(shí)接受的安檢步驟。

例句：
1. What is the procedure of the security check?
安全檢查的手續(xù)是怎么樣的?

2. Please move on to the security check passage.
請(qǐng)往前走，通過安全檢查通道。

3. Passengers are required to through security check.
旅客必須通過安全檢查。

4. The security check is for your safe. Be cooperative, please.
安檢也是為你的安全著想，請(qǐng)配合。
