We take fishes from the ocean-millions of kilograms of fish, every year, to51millions of people. We even52their bones for fertilizer. We take minerals from the ocean. One way to get salt is to53seawater in shallow basin and leave until it evaporates( 蒸发 ). Along with salt, other minerals are left 54 evaporation.Much gold and silver drift dissolved in the waters of the sea, too.

Seaweed becomes 58 of many kinds-even candy, and ice cream - as well as medicine. Believe it or not, fresh water is another 59 from the sea. We cannot drink ocean water. Some of its contents may. 60 illness. But ocean water becomes fresh water when the salts are 61 . In the future, we will find ourselves 62 more and more on fresh water from the sea. The sea63us food, fertilizer, minerals, water, and other gifts. What do we give the sea? Garbage. We pollute the ocean 64 we use it as a garbage dump. Huge as it is, the ocean cannot hold all the water that we pour into it. 65 garbage into the ocean is killing off sea life. Yet as the world population grows, we may need the sea and its gifts ,more than ever.请在第___________处填上正确答案.

根据以下材料回答下面的题目:The Emic and Etic ApproachesResearchers who are unfamiliar with the cultural and ethnic groups they are studying must take extra precautions to shed any biases they bring with them from their own culture. For example, they must make sure they construct measures that are meaningful for each of the cultural or ethnic minority groups being studied.In conducting research on cultural and ethnic minority issues, investigators distinguish between the emic approach and the etic approach. In the emic approach, the goal is to describe behavior in one culture or ethnic group in terms that are meaningful and important to the people in that culture or ethnic group, without regard to other cultures or ethnic groups. In the eric approach, the goal is to describe behavior so that generalizations can be made across cultures. If researchers construct a questionnaire in an emic fashion, their concern is only thatthe questions are meaningful to the particular culture or ethnic group being studied. If, however, the researchers construct a questionnaire in an etic fashion, they want to include questions that reflect concepts familiar to all cultures involved.How might the emic and etic approaches be reflected in the study of family processes? In the emic approach, the researchers might choose to focus only on middle-class White families, without regard to whether the information obtained in the study can be generalized or is appropriate for ethnic minority groups. In a subsequent study, the researchers may decide to adopt an eric approach by studying not only middle-class White families, but also lower-income White families, Black American families, Spanish American families, and Asian American families. In studying ethnic minority families, the researchers would likely discover thatthe extended family is more frequently a support system in ethnic minority families than in White American families. If so, the emic approach would reveal a more different pattern of family interaction than would the etic approach, documenting that research with middle class White families cannot always be generalized to allethnic groups.According to the first paragraph, researchers unfamiliar with the target cultures are inclined to__________
