It is in search of adequate food supplies that cetaceans, marine mammals such as whales and dolphins, travel the oceans. They live in a world that is largely hidden from humans. Yet their range is three times as large as ours, since oceans occupy about three-quarters of the Earth’s surface. They travel through well-marked ocean zones, each with its own characteristic marine life. They glide through the water, periodically rising to the surface to breathe. The word “each” in the passage refers to a A cetacean B surface C range D zone 文章中each指代,答案是D。 我认为是A cetacean, 因为 each指each of them, 指主语中的They, 即前面讲的cetaceans. 而且, zone with its own characteristic marine life讲得通吗? 谢谢指正
谢谢。还有两题的理解请指正 2.235词义 Based on his experiments, Von Frisch proposed that the dance indicates the location of food. proposed和含义 A supported B discussed C intended D hypothesized 答案是D, 我查英文字典propose=suggest 为何不选support?
2.8 细节 The other half involves using its 1,000-foot telescope to listen to nearby stars similar to the Sun that may have Earthlike planets orbiting around them. 问题According to the passage, NASA plans to direct its 1,000-foot telescope toward A Stars near the Earth B distant galaxies C planets in our solar system D the sun 我认为是选B,是否答案给错了?stars similar to the Sun中stars不会指太阳系中的其它和地球一样围绕太阳转的金木水火土了吧?请大家指正。

我个人觉得这道题可能要联系上下文吧.因为句子的意思是说" 在他的试验基础上,VF认为..."这个地方有take it considertation的意思,并没有表示他support什么东西,而仅仅只是根据前面得出的一个猜想,或者说还没有得到证实的东东,因此和hypothesized意思更接近. (当时这道题我也错了,也是想了很久)
