[1] While the Amazon may seem far away, we are all closely connected to it through our actions.

By being smart consumers, we can make a difference and help reduce human pressures on the forests and rivers.

as to why they fly that way.
As each bird flaps wings, it creates an uplift for the bird immediately following. By flying in V
formation, the whole flock at least 71 per cent greater flying range than if each bird flew on its own.
Individuals who share a common direction and sense of community can get where they are going more
quickly and easily because they are travelling on the pushing force of one another.
When a god se falls out of formation, it suddenly feels the drag and resistance of trying to go it alone,
and quickly gets back into formation to take advantage of the lifting power of the bird in front. If we
have as much sense as a goose, we will stay in formation with those people who are headed the same
way we are.
When the head goose gets tired, it moves back in the formation and another goose flies point. It is
sensible to take turns doing demanding jobs, whether with people or with geese flying south.
Geese honk from behind to encourage those up front to keep up their speed. What messages do
we give when we honk from behind?
Finally -and this is important -when a goose gets sick or is wounded by gunshot, and falls out of
formation, two other geese fall out with that goose and follow it down to lend help and protection.
They stay with the fallen goose until it is able to fly or until it dies, and only then do they launch out on
their own, or with another formation, to catch up with their group.
If we have the sense of a goose, we will stand by each other like that.
B. see the direction ahead clearly
C. fly at a higher speed and reach a further place
D. greatly reduce the risk of being hit by gunshots
B. To move.
C. To cry.
D. To fight.
B. We should work together with those who share our dream.
C. We should take our share of responsibility in a huge task.
D. We should encourage those falling behind to keep on trying.
B. To announce some new findings about geese.
C. To prove the similarities between humans and geese.
D. To persuade us to find more about life of geese.
From school to band Practice, the Venturi Eclectic is an Earth-friendly way to get where you want to go. This battery-powered, zero-emission (meaning it doesn't pollute the air) vehicle runs mainly on renewable energy. Solar panels on the Eclectic's roof absorb sun rays when you're driving. On windy days, you can connect a machine to the car's roof that collects energy from the wind while you're parked. The Eclectic's top speed is 28 miles an hour; the battery lasts for 31 miles before it needs to be recharged. Zipping (迅速行进) around the neighborhood has never been better.
Here's an eco-friendly way to tell time: Simply fill the Bedol Water-powered Clock's tank (箱) with water, add some lemon juice, and the clock will display the time without the need for environmentally harmful batteries. There are two sets of metal electrodes (电极) inside the water tank. Water contains ions (离子) that carry negative and positive charges. These ions complete a charge between the electrodes, creating enough energy to power the clock. Just refill the tank every few weeks, and this clock will keep on ticking.
Bloodhound SuperSonic Car (SSC) will be the first car to attempt to break the l,000-mile-an-hour barrier. (The current record is 763 miles an hour.) A concept for now, the rocket-shaped car gets its original push to 350 miles an hour from a jet engine. Then a rocket fires up, pushing the SSC past 1,000 miles an hour. In order to keep the car streamlined (流线型的), the driver lies back at a 45-degree angle (角度).
You’re having a blast at your friend’s birthday party. But when it's time to bring out the cake, everyone crowds around, blocking your view. No worries. Throw the Triops into the air, and this clever camera captures the view from above. The Triops can take three pictures at once, each from different angles. You can also record sounds and command the Triops to start shooting whenever it hears that noise. That's one smart camera.
What is the common characteristic of the Venturi Eclectic and the Bedol Water-powered Clock?
A. They don't need batteries. B. They are difficult to operate.
C. They can be powered by water. D. They are environmentally friendly.
According to the passage, the Venturi Eclectic .
A. is popular with businessmen B. is suitable for a long trip
C. can turn wind into energy D. has only a little gas emission
The underlined phrase “having a blast” in the last paragraph probably means .
A. looking at a picture B. enjoying yourself
C. blowing out a candle D. recording sounds
Which of the following is TRUE according to the passage?
A. The Triops is sensitive to sounds.
B. The driver of the SSC must be of great size.
C. The color of the Bedol Water-powered Clock is like that of lemon.
D. The SSC doesn’t have anything to do with a rocket actually.
