年度 英語 15 [II] Write (VI) opinions. Write your answer in about 100 English words, not counting punctuation marks. Mr. John Spence's opinion on e-bikes My electric bike is one year old on Thursday, and it was a 75th birthday present. I have only ever been a casual cyclist, but had given my old bike away, as my creaky knees combined with living at the top of a hill-meant that I rarely used it. But with my e-bike I feel so empowered. It is so easy to get around to do a few errands that it often seems quicker than using a car and having to find parking. If anyone is tempted by the idea, I strongly recommend giving it a try. Ms. Liz Ormond's opinion on e-bikes Mr. Spence's enthusiastic praise for e-bikes omits any reference to pedestrians. There is no mention that they are more dangerous than other bikes. Can he tell us what 19 OC DE BESLOT ACAI BESI TE OF 0.8. safety studies have been done in relation to pedestrians, particularly in shared space, and what discussions have been held with organisations such as the Royal National Institute of Blind People? Also, since the motors are effective enough to propel bikes loaded with shopping and children, what effect would the additional weight have in a collision with a pedestrian?

At that moment, a 77-year-old lady was walking on the sidewalk and moved toward the bicyclist. The student hit the lady. The collision caused the lady to fall and strike her head. She was transported to hospital, but died of her injuries two days later. At the time of the incident, the student was apparently holding a smartphone in her left hand and a drink in her right while steering the power- assisted bike. Moreover, she had an earphone in her left ear. Therefore, police arrested the student for breaking the new law and riding recklessly. Police are investigating whether the student noticed that the old lady was walking toward her. They suspect that she was not paying sufficient attention because she was operating her smartphone right up until the collision. Her court appearance date has not been decided yet.

I think that high school students in Japan should go to a foreign country on a school trip. I recommend for their school trip is Italy. I recommend it for two reasons. The city Firstly, Italy has the largest number of World Heritage sites. Forexample, Colosseum where wild animals were hunted and Domenico monastery displaying the Last Supper and so on Secondly, there are many unique cultures. = One of them is Venice Carnival. The festival where people wear luxurious costumes. Others Chrismas is a famous event where the whole family gathers together to eat and exchange gifts. In conclusion, I think that they should go to foreign country on a school trip better than domestic.
