五、One possible version
Cashless Society,Yes or No
E-Pay is becoming increasingly popular recently,making
us get access to a cashless society.People,however,differ in
their opinions on this matter.
18
Some students think it important to be cashless because
people can have a more convenient and comfortable life.
However,others think very differently.They said this kind of
consumption pattern is a threat to one's privacy and wealth.
Besides,it is easy for us to pay more than we can afford,so the
cashless society is not a necessity.
As far as I'm concerned.a cashless society has more
advantages over disadvantages.Although there are risks and
different voices,it is worthwhile saying yes to it.

②续写线索:到达山顶—一心情激动—一感悟
2.细读续写段首句,推测故事情节
由续写段首句内容“最终,我们到达了山顶。”可知,本段可
以写我们到达山顶之后激动的心情以及我的感悟。
One possible version
Eventually,we made it to the peak.Standing on the
peak,I saw a range of snow-capped hills beneath.A wave of
immediate excitement welled up in my heart,howling winds
also cheering for us."We make it!"I shouted crazily,
hugging my dad tightly,big tears rolling down my cheeks.
Years have passed since that mountain climbing,but Dad's
words have continued to be a life reminder for me-"Just one
small step at a time"will get me wherever I want to be.I also
think life is a journey.
