Activity 2: Read between the lines.
1. Why are the fish in the deep ocean among the strangest creatures on the Earth?
2. Do you think the world beneath the surface of the ocean is fascinating? Why?
3. What is ocean exploration about?

答案：  Activity 2： 1. Because some fish have evolved fascinating survival characteristics. For example, some fish have both male and female organs to increase the chances of reproduction, as fish are so scarce at these depths that it can be difficult for them to find a mate. 2. Yes. Because there are so many incredible geological formations as well as unexpected life forms that have become strangely adapted to their extreme environment. 3. Ocean exploration is about making discoveries, searching for things that are unusual and unexpected. Through ocean exploration, we collect data and information needed to address both current and emerging science and management needs. 

Activity 3: Read beyond the lines.
1. With so much of the oceans left to explore, what would you like to do in the future?
2. What advantages does it have to explore the ocean?

答案： Activity 3： 1. The world beneath the surface of the ocean is such an amazing place that there is much to be explored, which fascinates many of us. So I think what’s the most important is that we need to study to enrich our knowledge and be determined to engage in ocean exploration to serve all mankind in the future. 2. The exploration helps to ensure that ocean resources are not just managed, but managed in a sustainable way, so those resources are around for future generations to enjoy. Unlocking the mysteries of ocean ecosystems can reveal new sources for medical therapies and vaccines, food, energy, and more as well as inspire inventions that mimic adaptations of deep-sea animals. Information from ocean exploration can help us understand how we are affecting and being affected by changes in the Earth’s environment. Insights from ocean exploration can help us better understand and respond to earthquakes, tsunamis, and other hazards. All in all, exploration is the key to increasing our understanding of the ocean, so we can more effectively manage, conserve, regulate, and use ocean resources that are vital to our economy and to all of our lives.

5. The reproduction (reproduce) of the cells can be suppressed by bombarding them with radiation.
6. She stationed herself (she) at the window to await his return.
7. Congratulate yourself on the small achievements that will pave the way towards a larger (large) one.
8. She was motivated solely (sole) by self-interest.

Ⅱ. Fill in the blanks according to the text.
We look upwards and wonder what lies 1. beyond our planet. We send probes into the vastness of space to explore the unknown. We build space stations 2. to advance (advance) our understanding of the universe. Our curiosity about outer space has remained 3. unshakeable (shake). Meanwhile, it is estimated that more than eighty per cent of the world’s oceans are 4. unexplored (explore). So, if we want to find exciting new life forms as well as undiscovered and unusual 5. geological (geology) formations, the ocean is where we should also be looking. Then why don’t we dive to the bottom of a really deep ocean and take a long, close look 6. beneath the waves?
The first 200 metres of our dive takes us through what can be called the open ocean, where most visible light 7. exists (exist). Once past 1,000 metres, we have reached the deep ocean, where there is no light and temperatures drop just above 8. freezing (freeze). The pressures are huge and can be more than 100 times the pressure of the Earth’s atmosphere. On reaching the ocean floor, we may see shrimps and other 9. organisms (organism) around hydrothermal vents. On our journey down, we have been fascinated by incredible geological formations as well as unexpected life forms that have become strangely 10. adapted (adapt) to their extreme environment. With so much of the oceans left to explore, who knows what wonders still await us in the future?

答案： 1. beyond 2. to advance 3. unshakeable 4. unexplored 5. geological 6. beneath 7. exists 8. freezing 9. organisms 10. adapted
