1.试题一
题型介绍：本篇文章是论述海洋潮汐形成的科学实验说明文。共设置了五个问题，提问的主要对象是科学家对海洋潮汐现象的探索过程和结果。
出处：本题的答案是本书的第一篇第一章的内容；原文如下：
“At the turn of this century was discovered an interesting phenomenon relating to tidal motion. In the ocean depths water is permanently in motion due to the Earth’s rotation on its axis and its revolution around the sun (Figure 2). The surface of the ocean shows two high tides a day with respect to each other as well as a larger and smaller set of diurnal (daily) tides corresponding to the gravitational attraction by the Moon and Sun ， respectively. However， at deep oceanic trenches many hundreds of kilometers from the nearest coast where there are no tidal ranges associated with land masses or islands， one often finds that the rate of vertical motion of particles along the ocean floor exceeds that of gravity causing them to float upward like balloons （figure 4）.”
2.试题二
题型介绍：本文是与环境保护相关的讨论文章。提出了人类活动对环境的影响，以及应该采取的措施。设问主要对象是人类对于环境的破坏，如何采取措施进行应对。
出处：本题答案为第二章的内容。
“The use of fossil fuels， of course， has affected the environment in many ways. One consequence is a steady increase in the levels of atmospheric carbon dioxide， a gas that forms part of the greenhouse effect . Another effect has been an increase in the temperature of the oceans， which now appears to be rising at an average rate of 0.6℃ per decade . A further consequence will be the gradual melting of glaciers and the ice caps of Greenland and Antarctica， which together hold enough water to raise sea level by about 70 meters If this were to happen， it would inundate low-lying coastal areas worldwide and render unusable large regions now supporting heavy population concentrations （table 1）."
3.试题三
题型介绍：本文是一篇讲解细胞通讯与信号转达的文章。共设置了六个问题，问题主要是针对细胞通讯过程中各步骤的细节与联系。
出处：本题答案为第四章的前两段内容 “In summary， then， the cell membrane acts both as a selective barrier， letting nutrients pass into cells while blocking the passage of germs and toxic chemicals， and as a communication network， sending signals between cells and the outside world. It achieves these ends
