Smoking is harmful. But as soon as you quit the habit, everything will be OK, right?
Wrong.
New research has found that even if you give up smoking, the damage it has done to your
genes will stay there for a much longer time. In the research, a team of US scientists studied the
blood of 16,000 people. Among them, some were smokers, some used to smoke, and the rest
were non-smokers. Scientists compared their genes and found that more than 7,000 genes of
smokers had changed--a number that is one-third of known human genes.
According to NBC News, both heart disease and cancer are caused by genetic changes.
Some people may have had the changes when they were born, but most people get them in their
day-to-day lives while doing things like smoking.
When you stop smoking, a lot of these genes will return to normal within five years.
This means your body is trying to heal (治愈) itself of the harmful effects of smoking. But
the changes in some of the genes stay for longer. They can stay for as long as 30 years, It’s
almost like leaving a footprint on wet cement (水泥)----it will always be there, even when
you’ve walked away and when the cement becomes dry.
Although the study results may make people unhappy, there is a bright side: the findings
could help scientists invent medicine to treat genetic damage caused by smoking or find ways
to tell which people have heart disease or cancer risks.

Do you want to be productive（富有成效的）at work or at home? Here's what
you should do.
Turn off television
I used to tell myself that I needed a break. So, when the kids slept I turned
on the cable and watched whatever program that caught my fancy. Often, I found
myself not watching, just channel-surfing. And I didn’t end up watching a full
program. I decided one day to just give up on TV as it made me sleep late and
woke up exhausted（疲惫的）.
If you want to be productive, cut off TV. You are better off reading a book.
Without TV, I have managed to finish many books which I have bought but never
read.
Limit Internet Use
The other big distraction that can make you sleep late is the Internet.
Probably because you will be checking your emails, updating your blog, watching
YouTube, etc. Try limiting the use of it at home, or switch it to the morning
session.
Nowadays, I check all my personal emails early in the morning. When I get
into work, I find myself less tempted to check personal emails.
Know Your Priorities(优先考虑的事)
Really, it is all about the choices you make and the priorities you have.
If you know it is competitive out there in the world, how can you be a better
worker than the person who is also aiming for the position above you?
Rest Early, Rise Early
You want to be productive? Rise early, read more books, have more energy,
be more focused and set standards for others to catch up. It’s as simple as
that. 5．The passage aims to give advice on how to ________.

B．balance our work and energy well.
C．divide time between work and family.

When we talk about stars, especially women stars, it seems that they are
always young, pretty and own charming body shapes. But recently a Britain's Got
Talent（英国达人）star Susan Boyle has changed our views absolutely.
Simon Cowell, one of the judges of the talent show spoke of his shock over
