在街上你看到七八十岁的老太太推着上千斤的垃圾，一点都不感到惊奇。

You may not surprise if you see a seventy to eighties years old woman push a half ton trash cart.

小平头、灰涤卡、圆日鞋，黑里透红的脸庞布满了皱纹，58岁的人看起来却有七八十岁。

Shoe of small crew cut, grey dacron drill, round day, black in rubicund face bestrewed furrow, person of 58 years old has 779 years old however it seems that.

比起七八十岁的老人，年轻点的需要补助的人更愿意享受生活，不愿过度担心他们留下的遗产。

New pensioners, it seems, are far more willing to enjoy life and less likely to worry about the inheritance they will leave than are septuagenarians and octogenarians.

是七八米高？

Is it 78 metres high?

现在一天通常写七八千字。

Now I typically write about 7,000 to 8,000 characters a day.
