D．Pay attention to the pre­flight safety briefing.

　　E．Keep our seat belt fastened while you are seated.

　　F．Air travel is the safest way to travel.

　　Statistically，air travel is by far the safest way to travel，and you can make flying even safer，just by following these simple rules.As your chances of being involved in an air accident are practically nil (零)，many of these tips concern what you should and shouldn't do to make your journey safer when you are airborne (升空的)．

　　1.

　　Most accidents occur during the take­off，climb，descent and landing phrases of a flight，so flying non­stop reduces your exposure to these complex procedures.

　　Choose larger aircraft.

　　Although small aircraft have very good safety records，those with more than 30 passenger seats are designed to comply with much stricter regulations and are tested more regularly to make sure they still comply.Also，in the unlikely event of a serious accident，larger aircraft provide a better opportunity for passenger survival.

　　2.

　　The information may seem repetitions (重复的)，but it's worth listening to the flight attendants.And even if you've flown before，it doesn't mean you know everything about the aircraft you're on，such as the location of the closest emergency exit.

　　3.

　　Never put very heavy articles in the overhead storage bins.They may fall out when someone opens the bin and cause injury.Also，the bin may not be able to hold heavier objects during turbulence (气流)．

　　4.

　　Cabin crew always tell you this，but it's important.You would be seriously injured if the plane hits unexpected turbulence.Always fasten your seat belt if you are told to.The general rule of flying is this：If you are told to do something，do it first and ask questions later.

　　5.

　　Flight attendants are trained to handle hot drinks like coffee or tea in a crowded aisle on a moving aircraft，so allow them to pour the drink and hand it to you.Never ask to take a coffee pot from one of them.

　　Ⅳ.短文改错

　　Ⅰ.单项填空

　　1．D　句意为：你认为他到这里有多久了？since自从，引导的状语从句用一般过去时态，主句用现在完成时态，指段时间可用一般现在时态。

　　2．D　此处sound为连系动词，意为"听起来"，后面可用形容词、名词或介词短语作表语。此处省略了主语that或it。
