The conservative (保守) choice is to kick the ball and accept temporary defeat in order to gain a good position for your team the next time it gets the ball. The more exciting choice, however, is to try a fourth and final time to gain the remaining yards needed.

[单项选择]The use of chemicals in almost all areas of life has become a commonplace phenomenon. There is growing evidence, however, that chemicals in the environment, including pesticides, may contribute to some illnesses. While studies are still being conducted, preliminary conclusions point to the verdict that such chemicals are indeed negatively impacting those humans to whom they are exposed.
Children are especially vulnerable to toxic substances. Pound for pound, they eat, drink and breathe more than adults, all of which exposes them more heavily to those chemicals to which most individuals encounter on a daily basis.

Questions from 31 to 35 are based on the following passage: Generally, cargo is carried in containers, but sometimes it is still shipped as breakbulk cargo. During the voyage, goods may be stacked on top of or come into violent contact with other goods. And the cargo might be dragged, pushed, rolled, or dropped during unloading, while moving through customs, or in transit to the final destination.

If the buyer does not specify this, be sure the goods are prepared using these guidelines: Pack in strong containers, adequately sealed and filled when possible. To provide pro

B. heavier than that of the freight carried by sea
