4 . Personally I think trains are exciting and romantic. I must admit that trains are not important means of trasportation in the US, but I do have some experience with them.

When I was a child, growing up in a small town with very little entertainment, we used to go to the station to watch the passenger trains coming in. There was something exciting about the steaming, roaring string of trains coming into view around the mountains, slowly growing larger and louder and finally after their stop crowds of strangers pouring onto the platform.

I took my first train trip when I was ten years old. I went with my elder sister to visit our cousins six hundred miles away. The train- so loud and violent on the outside — was gentle and rocking inside. We were very excited, and as that was also our first time away from our parents, we felt somewhat frightened too. However, because I had expected so much, I was a little disappointed when I was finally one of the passengers I had watched for so long.

As a college student, I used to ride an overnight train to my roommate’s hometown. We could never afford a sleeper, so we played cards, sang, ate, read and talked until we finally fell uncomfortable asleep in the straight-backed seats.

My idea that trains are romantic may come from the fact that my husband and I took the train on our honeymoon, spending extra money to eat in the dining car, and looking out of the window as the desert scenery slid past.

Now, when I make a trip, I always fly or drive, and trains are not a very important part of my life. Still, every time I hear the train whistle far away on a quiet night, I can always feel the impulse in my heart to pack my bags and jump on board, entering a unique world of motions, sounds, sights and experience which just aren’t matched in the dull environment of an airplane.

7 . Tesla’s self-driving cars have recently come under investigation as a report on crashes raises questions about their safety. Despite Tesla CEO Elon Musk’s claim that their Autopilot capability makes their cars “ extremely safer,” data suggests otherwise.

According to The Washington Post, the number of deaths and serious injuries associated with Tesla’s driver-assistance technology is higher than previously reported. The National Highway Traffic Safety Administration (NHTSA) recorded 736 crashes since 2019, with at least 17 of them being fatal. These figures include crashes involving both Autopilot, which allows cars to drive on highways without human intervention(干预), and the newer Full Self-Driving feature, which extends automation to city streets. However, these statistics can’t record incidents that were avoided due to the cars’ safety features. Additionally, when compared to the total number of car crashes that occurred last year, the number of crashes involving driver-assistance vehicles appears relatively small, but actually it’s not.

Tesla’s safety claims lack context as Autopilot is primarily designed for highways, while most accidents occur in more complex environments with cross-traffic, pedestrians, and cyclists. Moreover, Tesla’s customer base consists mainly of wealthier individuals who live in communities with lower accident rates.

Concerns are raised by Tesla’s request to the NHTSA not to reveal whether Autopilot or Full Self-Driving was in use during fatal crashes. This lack of transparency (透明) prevents a comprehensive analysis of the incidents and raises questions about responsibility.

Safety exaggerations combined with Tesla’s aggressive marketing have led to accidents caused by drivers relying too heavily on the system. Full Self-Driving does not allow the car to fully drive itself, and drivers are expected to remain attentive and ready to intervene at all times. However, Tesla’s messaging may mislead some users into believing otherwise.

While a driverless future has the potential to be safer, it is crucial not to convince the public that underdeveloped capabilities are ready for widespread use. Tesla should address past problems, ensure their automation set can detect(检测) emergency vehicles, and be transparent with the public about the limitations of their technology.
