[求助]Delta 2.6顺序题，头痛

college

one product of a thunderstorm is the onset of a hailstorm. Inside the clouds, violent air drafts cause water droplets to become supercooled. At zero degrees, the water droplets turn to ice crystals if there's also a catalyst present, in the form of tiny particles of solid matter. Ice forms around the particles,  and supercooled water continues to coat them. They grow into rounded icy masses, becoming hailstones when they reach a diameter of 5 milimeters. Hailstones hit the ground with a loud rattle when they hit buildings and roads. Think of a hailstorm as a giant pummeling machine. It can be the most damaging part of a thunderstorm because of  the damage it causes to crops.

the given answer correct order is :

1.water freezes around particles of solid matter

2.hailstones strike the ground with force

3.rounded icy particles grow into hailstones

4.water droplets in a cloud become supercooled

please help me comprehend the correct order .

i think it's 2431

个人认为4132

water先变成过冷supercooled液体（4），之后如果出现了catalyst催化剂的话，它可以先成凝结核，之后其他液体围绕着这个凝结核再扩大（1），之后就变得更大了成了stone（3），只有成为了stone才可能砸在地下吧（2）

呵呵，怪我没说清楚啊，我和你排的是一样的，只是我是直接在前面标注 ：）

答案就是上面显示的1234

你可以到书的274页看，就是Delta的听力2.6 FOCUS往下看：）
