1. New water-current patterns have brought more mixing of the Thalian Sea's shallow waters with nutrient-rich deeper waters. For coral and algae, both of which inhabit the shallow waters, growth rates depend principally on availability of nutrients and sufficient sunlight. The algae's rate of growth has increased, yet the coral's growth has slowed. Since algae can block sunlight from reaching coral below, the slowed coral growth is probably attributable to increased algae growth.
Which of the following, if true, most strengthens the argument?C和A都生活子浅水并且需要获得阳光。A的生长率上升了,而C下降了,因为A可以阻挡C获得阳光,所以是A导致了C生长慢
A. The new water-current patterns in the Thalian Sea have increased the concentrations of industrial pollutants in its shallower parts. 跟工业污染无关
B. In those areas of the Thalian Sea where there has been the greatest increase in algae growth, the growth of coral has stopped altogether. 有些地方A很多,C没了,正说明推论
C. In some areas of the Thalian Sea where shallow water receives abundant sunlight, there is no coral and there are only small amounts of algae. 不符合上文说的条件
D. Many of the nutrients essential to the growth of algae play no role in the growth of coral. 无关
E. The mixing of the sea's shallow waters with nutrient-rich deeper waters is expected to diminish after this year. 无关
2.A magazine invited readers to perform an experiment: have one friend sit blindfolded while another, seated behind the blindfolded person, peels a sticker off the magazine and then look either at or away from the blindfolded person on the basis of the instructions under the sticker. According to the responses received by the magazine, the blindfolded people, in a proportion greater than chance, correctly judge whether the person behind them was staring at them.
In order to evaluate the results of the experiment, which of the following would it be most important to establish?
参与实验要求一个蒙眼的人坐在蒙眼的人后面,撕下一张杂志后要么看对方或者不看对方,根据反馈调查是否蒙眼的人能够判断出别人的目光
A Whether the blindfolded person was generally told after the experiment was finished whether his or her answer had been correct? 无关
B Whether the magazine published a time limit within which the experiment was to be conducted? 无关
C Whether the peeling off of the sticker would have been audible to the blindfolded person? 有没有声音无关
D Whether the readers of the magazine sometimes fail to report results indicating an incorrect judgment by the blindfolded person?
B D
E Whether inviting readers to take part in the experiment was intended to foster reader loyalty? 无关
