Our environment isn't as green and beautiful as it should be.There are steel monsters blocking out the sun. blowing out dangerous smoke,and letting out poisonous chemicals into rivers,cars producing harmful waste gas, people throwing out waste in a wrong way and all other kinds of sources that ruin the planet.Facing current environmental problems,people need to do their best to save the earth.

You cart see many big garbage dustbins in the streets.They're not there for a show,but for you to drop your waste.We should realize that what we do does count.So next time you get that urge to throw gum or a chocolate package out of the car window,or "accidentally" drop as you walk down the street,ask yourself how much waste you've been contributing to the environment with that bad habit going on for years.

At home,the first thing we can do to protect the environment is avoid letting water run continuously and make sure that taps are not leaky（漏的）,which would help greatly in scrimping.Another is to use energy-saving lights,and turn them off before you leave the rooms.It is not only energy-saving,but also cuts down electricity costs.

Recycling is a method to make items reusable.Many things you want to throw out can be made into new products through the reproducing process.Use your imagination to come up with ways on things that you can use again.

Pass the message of simple ways to save the environment on to kids.Starting with kids is a good way of teaching the message early in their lives,in the hope that they can carry it forward as they grow older.

With environmental protection awareness in mind,we can do what we can,for the results are to have a big effect on the planet.As long as we do our part,the world is one small step closer to being saved.

You drive down the highway with your family or friends in the car,camping equipment and spare clothes in the back.Your windows are down and the wind is hitting you in the face.These are the makings of a classic US road trip.

Road trips are quite common in the country,especially during the Thanks-giving holiday,which is the busiest travel time of the year in the country for families and friends who want to get together.

And for students,going on a road trip is traditional after graduating from high school or college with their schoolmates.It usually involves traveling great distances across the US and camping out whenever possible. Destinations are different depending on where in the country someone is located.But they all show the same kind of adventure.Popular spots to travel to include Yellowstone National Park,the Grand Canon.

However,the most famous of all road trip journey is travelling across the US on Route 66.Route 66 begins in Chicago and ends in Los Angeles.The route goes past many of the lesser-known states.However,it's the bizarre（稀奇古怪的）and wonderful small attractions that draw many road trippers to them.The attractions one sees on these trips are quite strange and very difficult to explain to non-American.They are filled with gas stations that still look like they did back in the 1950s and small restaurants known as "mom and pop restaurants" where you can eat a greasy cheeseburger with a delicious milkshake.Route 66 is also filled with quite unusual,but still fascinating wonders.

Deep down,US road trips show the spirit of freedom and openness.The idea is that if you have a car,you have freedom to escape,to discover,to find yourself,to lose yourself.It's a powerful call,one that is part of the US' identity and culture.It is a must-do for anyone who plans to spend time in the US to see the country and all of its wonders.An old saying—"It's not the destination,it's the journey"—best explains what the experience of a road trip truly offers.

The answer to protecting and saving marine(海洋) wildlife can start with cutting back on something Americans use every day—plastic drinking straws. Actor Adrien Grenier, best known for playing Vincent Chase in 2015 movie Entourage, has launched a campaign to reduce the amount of single-use plastic usage in this country in order to protect and save marine wildlife and the environment. Plastic drinking straws are among many single-use plastic products contributing to the shocking loss of marine life, but they’re a great place to start because they’re something Americans are using by the hundreds of millions without any awareness that they’re so damaging.

According to Ecocycle, an international environmental organization, Americans use more than 500 million straws daily, which are enough to fill 127 school buses each day, and they can’t be recycled. They means plastic straws end up in landfills or oceans, where fish and other marine wildlife mistake the small bits for food and swallow them. After seeing a photo of a whale beached on the shore with a belly full of plastic, Grenier felt the inspiration to launch the Lonely Whale Foundation, hoping to inspire and educate others on the challenges facing marine life.

Along with stopping the use of straws, Grenier hopes to educate consumers on the dangers of other single-use plastic items such as grocery bags and water bottles. While many Americans use these plastic products in their daily life, there are more sustainable alternatives that can help protect the environment. Ecocycle recommends the use of straws made from stainless steel, glass, and even bamboo instead of plastic. You can buy a number of these environmentally friendly straws online and in stores.

1.What initially contributed to the start of Grenier’s campaign?

A. Plastic straws in landfills.

B. A picture of a dead whale.

C. The severe damage done to the sea.

D. The disappearance of some species under the sea.

2.What is the primary purpose of the Lonely Whale Foundation?

A. To advocate a green lifestyle.

B. To promote Grenier’s latest movie.

C. To save precious natural resources.

D. To encourage people to protect ocean life.

3.Ecocycle advises people to use straws that are ________.

A. easy to recycle

B. convenient to use

C. special to marine life

D. harmless to the environment
