1 . Any car accident is frightening, but an accident in which your vehicle is thrown into the water, with you trapped inside, is absolutely terrifying.     1    However, most deaths result from panic, without a plan or understanding what is happening to the car in the water. By adopting a brace(支撑) position, acting decisively and getting out fast, you can save yourself from a sinking vehicle.

Brace yourself for impact (撞击力). As soon as you're aware that you're going off the road and into a body of water, adopt a brace position. The impact could set off the airbag system in your vehicle, so you should place both hands on the steering wheel in the “ten and two” position.

Undo your seat belt.     2     Unfasten the children, starting with the oldest first. Forget the cell phone call. Your car isn’t going to wait for you to make the call.

    3     Leave the door alone at this stage and concentrate on the window. A car’s electrical system should work for up to three minutes in water, so try the method of opening it electronically first. Many people don’t think about the window as an escape option either because of panic or misinformation about doors and sinking.

Break the window. If you aren’t able to open the window, or it only opens halfway, you’ll need to break it with an object or your foot. It may feel counterintuitive (有悖常理的) to let water into the car.     4    

Escape when the car has equalized. If it has reached the dramatic stage where the car cabin has been filled with water and it has become balanced, you must move quickly and effectively to ensure your survival.     5     While there is still air in the car, take slow，deep breaths and focus on what you’re doing.

A．Open the window as soon as you hit the water.

B．Surviving a sinking car is not as difficult as you think.

C．It takes 60 to 120 seconds for a car to fill up with water usually.

D．Such accidents are particularly dangerous due to the risk of drowning.

E．In conclusion, if you know what to do in the water, you will be safe.

F．This is the first thing to attend to, yet it often gets forgotten in the panic.

G．But the sooner the window is open, the sooner you can escape directly through it.

2 . 根据短文内容，从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
If you are in a crowd, the first and most important thing is to make yourself familiar with your surroundings and mentally notice alternate exits.    1    Make yourself aware of the type of ground you are standing on, and know that in a crowd of moving people wet or uneven ground can be slippery or hazardous, causing you to fall.    2    When in danger, a few seconds can make all the difference, giving you the possibility of taking advantage of escaping route. Always stay closer to the escape route.If you find yourself in the middle of a moving crowd, do not fight against the pressure, do not stand still or sit down, because you could easily get trampled.    3    Take advantage of any space that may open up to move sideways to the crowd movement where the flow is weaker.Keep your hands up by your chest, like a boxer—it gives you movement and protects your chest.    4    If you cannot get up because you are injured, get someone to pull you back up. If you have kids, lift them up.If you fall and cannot get up, keep moving by crawling in the same direction of the crowd, or if that is not possible, then cover your head with your arms and curl up into fetal position.    5
