Coffee drink is widespread. When people argue about whether coffee is good for health, they’re usually thinking of the health of the coffee drinker. Is it good for your heart? Does it increase blood pressure? Does it help you concentrate? However, coffee affects the health of the human population in other ways, too.

Traditionally, coffee bushes were planted under the shade of taller trees. However, more and more farmers in Latin America are deforesting the land to grow full sun coffees. At first, this increases production because more coffee bushes can be planted if there aren’t any trees. With increased production come increased profits.

Unfortunately, deforesting for coffee production immediately decreases the local wildlife habitat, because native birds nest and hide from predators（捕食者）in the tall trees and migrating birds rest there.

Furthermore, in the long term, the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides（殺蟲劑）are needed to grow the coffee. The fertilizers and pesticides kill insects that eat coffee plant, and then the birds eat the poisoned insects and also die. The chemicals kill or sicken other animals as well, and can even enter the water that people will eventually drink.

Fortunately, farmers in Central and South America are beginning to grow more coffee bushes in the shade. We can support these farmers by buying coffee with such labels as "shade-grown" and "bird-friendly".

Sure, these varieties might cost a little more. But we're paying for the health of the birds, the land, ourselves, and the planet. I think it’s worth it.

1.Which opinion does the author agree with?

A. People should buy full-sun coffee.

B. Shade-grown coffee should be supported.

C. Farmers should change the places to grow coffee.

D. Pesticides should be forbidden in coffee planting.

2.Compared with the traditional method, what advantage does the full-sun method have?

A. It can protect the ecosystem.

B. It can promote people's health.

C. It can provide mare nests for birds.

D. It can increase the production of coffee.

3.How do farmers get more land to grow full-sun coffee?

A. They cut down trees.

B. They move to other countries.

C. They turn grassland into farmland.

D. They buy more land from other farmers.

4.What can we learn from the passage?

A. It is quite worthwhile to buy shade-grown coffee at any cost.

B. Farmers all have realized the importance of protecting the environment now.

C. South American farmers are taking action to plant coffee in the traditional way.

D. The full-sun method does good to the health of human beings in the long run.

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（疲憊的）.

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(優(yōu)先考慮的事)

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.

1.The passage aims to give advice on how to ________.
