Dear friends,

As we can see, the environment around us is getting worse other than better. Our life and health have affected greatly. The earth is our home, but we have a duty to take care of it, not only for ourselves but for future generations. Fortunate, more and more people have become aware of this problem. Many effectively measures have been taken by the government to deal with them.

As a student, I think we should do what we can improve the environment. First, go to school on feet or by bike as often as possible. Second, turn on the lights and other electrical appliances before leaving the room. Third, never throw rubbish here and there.

It’s time that we do something to protect our environment.

 

Now then, children, it's time you_____________.

A．washed and dressed	B．are washed and dressed
C．will wash and dress	D．were washed and dressed

 

–– It is ridiculous that John wants to make academic progress but never devotes any time to it.

––– Maybe it’s time for him to know______.

A．heaven never helps the man who will not act

B．he who makes constant complaint gets little compassion.

C．hope for the best, but prepare for the worst

D．It is easy to be wise after the event.

 

As dangerous as sharks may have seed to people after watching Jaws, which was released on June 20,1975, the recent disastrous decrease in their numbers show that people have proven far more dangerous to sharks.

    This disastrous decline is due in large part to commercial fishing of sharks. “The market for

shark fins（鱼翅）in East Asia opened up thanks to changes in their economy, increasing their

ability to spend money on things such as shark fin soup,” Burgess said.

However, the biggest worry for sharks and their relatives, the skates and rays, which are suffering a similar fate, “is how they are killed incidentally when fishermen try and take other fish—the problem of bycatch（渔业混获）,” Burgess explained. “They may be thrown back afterward, but they’re still dead.”

The key of the problems behind bringing sharks back is that “they’re not the same as other fish,” Burgess said, “Sharks are slow growing and slow to reach maturity. Sharks are live bearers, which means females keep their young in their body just like us, but instead of nine months, it takes 12 to 18 months or more in sharks. Also, sharks generally can’t give birth again until a year after they’ve given birth—sometimes they’re on a three-year cycle. So once you get a shark population knocked down, this ‘life in the slow lane’ means that recovery is measured in decades rather than years.”\

Burgess said, “I’m on the recovery team for it, but the recovery plan for that is over the course of 100 years. So I won’t see them recover, nor will you, nor will your children. That’s what it means when these animals go down—they’re down a long time.”

Any measures aimed at saving sharks must not only consider byeatch, “which is the real killer right now,” but also encourage interactional cooperation, Burgess said.

“Sharks are very migratory, and many species cross borders,” he said. “We can protect them only by getting many govemment to come aboard. That’s the hardest part about this.”
