1.A) There are many causes of traffic jams/ congestion :

Chaos on the road 

It is time-consuming

It makes it difficult for motorists and commuters to reach their destinations on time

This has an impact on the countries economy – some people get relieved from their duties due to unpunctuality, some are demoted

b) People can do many things to help such as: avoid using too much personal vehicles, trying using public vehicles, waiting for a short amount of time after work to pass the prime time of traffic congestion,...

c) I would like to go to school on my own foot because i live in a nearby house and it doesn't take much time to walk to school. Moreover by walking I can also improve my endurance and reduce the time needed for passing over people who are waiting to place their bicycles in the space-for-parking.

2) I really love to travel a long distance as it certainly helps me to explore the world and stimulates my curiosity. I usually travel by train, I don't know the reason why but each time i go on travelling by train, my heart beats faster and it makes me inquisitive.

3. I would like to see action movies as I see the actors really cool when they could do all those dangerous scene by themselves. One film of this kind I have watched recently is Mission Impossible 8: Fall out; it whetted my appetite and it's just right for me. I even have crush on the actor in the leading role: Tom Cruise as he is so patient, brave and have good fighting skill.
