TPO5的第一篇总结题:
Plants need to absorb certain minerals from the soil in adequate quantities for normal growth and development.




Answer Choices
1. Some plants are able to accumulate extremely high levels of certain minerals and thus
can be used to clean up soils contaminated with toxic levels of these minerals.

2. Though beneficial in lower levels, high levels of salts, other minerals, and heavy metals can be harmful to plants.
3. When plants do not absorb sufficient amounts of essential minerals, characteristic abnormalities result.
4. Because high concentrations of sodium chloride and other salts limit growth in most plants, much research has been done in an effort to develop salt-tolerant agricultural crops.
5. Some plants can tolerate comparatively low levels of certain minerals, but such plants are of little use for recycling nutrients back into depleted soils.
6. Mineral deficiencies in many plants can be cured by misting their roots with a nutrient solution or by transferring the plants to a soilless nutrient solution.
答案是123,我怎么看是46也对呢,看不出来123是强调的,怎么办啊


TPO5的第二篇最后一题:
Together, Melanesia, Micronesia, and Polynesia make up the region described as the Pacific islands, or Oceania.


Answer Choices
1. The first Europeans to reach the area assumed that the islands’ original inhabitants must have drifted to Oceania, perhaps from Egypt or the Americas.
2. It is now believed that the process of colonization required a great deal of skill, determination, and planning and could not have happened by chance.
3. Using linguistic and archaeological evidence, anthropologists have determined that the first Pacific islanders were Austronesian people from Southeast Asia.
4. New evidence suggests that, rather than being isolated, Pacific islanders engaged in trade and social interaction with peoples living in Southeast Asia.
5. Although early colonizers of the islands probably came from agriculture-based societies, they were obliged to adopt an economy based on fishing
6. Computer simulations of the winds and currents in the Pacific have shown that reaching the Pacific islands was probably much easier than previously thought.
答案是123,我选的是136,这种题都是错,怎么办呢,就算看了答案还是不太懂,我选的和答案不一样,谢谢帮忙!!!

没人解答,还是顶一下,还有个问题,
TPO6的第二篇,William Smith,最后一个summary题目,14. William Smith’s contributions to geology have increased our knowledge of the Each’s history.
Answer Choices
1.Smith found success easily in his profession because he came from a family of geologists and surveyors.        
2.Smith’s work on canals allowed him to collect fossils and study rock layers all over England.
3.Smith found that fossils are much more reliable indicators of geological time than rock strata are.
4.Smith was named “the father of English geology” for his maps rather than for his other contributions to the field.
5.Smith and Cuvier discovered that fossil patterns are easier to observe in ancient rock strata than in younger rock strata.
6.The discovery of the principle of faunal succession allowed geologists to establish the relative age of Earth’s rock layers.
答案是236,3 怎么对了?我选的4,急救,谢谢
