The street lights were shining, causing rather sad feelings. I wandered aimlessly.

A young father who held a child in his arms walked past me. I felt as if I saw my childhood from another space: happy and carefree.

But now … I don’t know whether it is because I have grown up or because dad is getting old. We differ in our ways of thinking. We are just like two people coming from two different worlds. It feels like there is an iron door between us that can never be opened.

I wandered the streets, without a destination in mind. My heart was frozen on this hot summer night. As I walked on, there were fewer and fewer people on the streets, until I had only the street lights to keep me company. When I finally reached the high-rise apartment block in which I lived, I saw that the light was still on.

I thought to myself: “Is father waiting for me, or is he still angry with me”

In fact, it was nothing. Perhaps, dad was throwing away some of his old stamps. Perhaps he thought they were useless. I never had the courage to tell him that I liked collecting stamps.

All the lights were off except father’s.

Dad was always like this. Maybe he didn’t know how to express himself. After shouting at me, he never showed any mercy or any moments of regret.

This was how he always was. He has been a leader for so long that telling everyone else what to do has become his second nature.

The light was still on. “Am I wrong” I whispered, maybe… With the key in my hand, I was as nervous as I had ever been. At last, I decided to open the door. As soon as I opened the door, tears ran down my cheeks. I suddenly realized that the iron door that I had imagined between us did not exist at all. Love----it’s second to none.

Many people have wondered what makes the oceans rise and fall on the word’s beaches twice a day. Those tides are caused by the force of the Moon’s gravity and the rotation(自转) of the Earth. Gravity acts on the center of any solid object. The Earth is mostly molten(熔化的) rock, but compared to the oceans, we can think of it as a solid object.

As yoknow, the oceans are fluid and lie on the surface of the Earth. When the Moon is overhead, the oceans are four thousand miles closer to the Moon than the Earth’s center is. Because the oceans are closer, the Moon pulls harder on the water than on the Earth. This stronger pull makes the water bunch up(集中) a little under the Moon, creating a high tide.

At the same time, the oceans on the opposite side of the Earth are four thousand miles farther from the Moon than the Earth’s center is. The Moon’s pull on this water is weak. This water bunches up because it is “left behind”(making another high tide) as the Earth is pulled slightly towards the Moon.

When the waters bunch up on these two sides of the Earth, they draw water away from the other sides of the Earth, which creates the low tides.

As the Earth rotates, different parts of the land and oceans pass through the high-tide and low-tide zones. And that makes the waters on our coasts go up and down.

33. According to the passage, there would be no tides if there were no ______.

A.Earth rotation

B.gravity from the Earth

C. gravity from the Moon

D.Moon’s gravity or Earth rotation
