Question: Talk about the pros/cons of this era as it is full of daily inventions. Use examples of any recent inventions that you think proved beneficial or detrimental to the society.
和那些问你What is your opinion? 的题不同的是，这道题非常明确地指出了文章必须包含优点和缺点，所以我不需要纠结于自己应该是中立还是一边倒。但有些同学可能会疑惑于是否要找出一个即有优点又有缺点invention。实际上，并不需要，我们可以分开找那些有优点的和缺点的invention。
· hybrid/electric cars,
· smart phones,
· web/internet TV
Pros (hybrid/electric cars):
much less emission, environmental friendly, no noise pollution, more power efficient,
Cons (smart phones):
2. Sedentary lifestyle
1. Less face to face communication chances with your families, friends,
2. Very likely to be addicted to video game
In my opinion, recent technology breakthrough related to renewable energy is the most significant advantages for this era. One example of this could be the wide use of electric cars these days. Due to the fact that it uses renewable energy rather than traditional petrol, it produces much less waste gas which might increase the severity of greenhouse effect. Moreover, as it mainly uses electricity to drive, it makes nearly no noise and is very energy efficient. Thus, with such environmental-friendly inventions, this era’s advantage should be recognized.
