     During the 19th century, it was common to hear people in Europe and America say that the

resources of the sea were unlimited. For example, a noted biologist writing in the mid-19th century

commented that none of the great sea fisheries(渔业) are to be exhausted. Today though, there is

evidence that the resources land and the air,  and that the endangered species (种类) include Herring

and Carp as well as the African Elephant, Indian Tiger, and the American Eagle.

     Further, the threats to fish are more alarming in some ways than the threats to animals and birds.

     This is because fish are a much needed food resource and people throughout the world depend on

fish as an important part of their dish,  and the decline (下降) in the fish supply could have extensive

effects on hunger and population.

     Fishermen in the North Atlantic alone annually harvest 20 billion pounds of fish to satisfy food

demands, but it is important to recognize that these practices cannot continue without depleting (耗尽)

fish storage within the next few years. Sea resources are rapidly declining in many parts of the world,

and the problem cannot he ignored (忽视) .

     We can predict that food supplies in the sea can not last forever.

1. According to the speaker, what was the attitude(态度) in the 19th century toward resources of

the sea?

A. Declined.              

B. Depleted.

C. Limited.                

D. Unlimited.

2. What is the range(地带)  of the decline in fish supply?  

A. Europe and Asia.        

B. The whole world.

C. Asia and America.      

D. America.

3. What does the author believe about sea resources?   

A. Sea resources can last forever.

B. None of the great sea fisheries are to be exhausted.

C. Fish supply has no effects on people.

D. Sea resources are important to people.

4. Which of the following best describes the purpose of the lecture?

A. Unlimited Sea Resources

B. Threats to Animals and Birds

C. Sea Resources on the Decline

D. Protection of Fish

     As parents, I do not believe that any of us sets out to raise a child that is disrespectful or bratty (无礼的).

Here are some helpful tips on how to raise a bratty child so that you can have a child that will be a benefit to

society.

     It doesn't take long for a toddler (学步儿童) to toddle right into trouble of some kind. This is the perfect

time for parents to teach the child not to do that action again. 1_____ Helping a child to behave in an acceptable

manner is a necessary part of raising the child well. Discipline is a useful teaching tool to guide a child. I think

it's necessary to explain to children what responsibility means. Responsibilities mean the things you have to do.

As parents, you should say to your children "If you play with your toys, it's your responsibility to put them

away." Besides, coach your children in their responsibilities. 2_____ 

     Children should use their time well. We can't let a child do the same thing again and again. When kids are

bored, they can end up in trouble creating problems for themselves and others. 3_____ Children should be told

not to waste their time and they should make full use of their time to do useful things.

     The children who are eager to increase their pocket money should be taught that money does not come

easily. For example, when parents buy school lunch for their children, they should put this spending into

children's pocket money. If children want to get much more money, parents can ask them to cook the lunch

themselves. 4_____ Parents should let their children know how to be in charge of their "expenses" and manage

their expenditure (花费). 

     5_____ It is your responsibility to help and guide your kids. So, the next time you see a bratty kid remember:

they didn't get that way themselves, and they have parents who didn't take time to teach them.

A. Parents should be strict with children.

B. You, the parent, whom kids rely on.

C. This process is called discipline.

D. You should encourage children to be kind.

E. I think it's very important that kids should be coached and not just lectured to.

F. Parents should encourage their children to save their pocket money.

G. Sports, activities and chores are a few things to help give kids something to fill their time.
