Strange things happen to time when you travel because the earth is divided into twenty-four zones (时区), one hour apart (一个时区相差一小时). You can have days with more or fewer than twenty-four hours, and weeks with more or fewer than seven days.

If you make a five-day trip across the Atlantic Ocean (大西洋), your ship enters a different time zone every day. As you enter each zone, the time changes one hour. Traveling west, you set your clock back, traveling east you set it ahead. Each day of your trip has either twenty-five or twenty-three hours.

If you travel by ship across the Pacific (太平洋), you cross the international date line (国际日期变更线). By agreement, this is the point where a new day begins. When you cross the line, you change your calendar one full day, backward or forward. Traveling east, today becomes yesterday, traveling west, it is tomorrow.

When we have small cuts in the skin(皮肤), something strange may happen. The cuts are able to heal(痊愈) themselves in a couple of days. How does this happen? Read on, and you will find out the secret.

Every living thing on the earth is made up of cells(细胞). Cells grow and make new cells. Most cells are very small and we can't see them with our eyes. Different cells have different uses. Our skin cells are special ones. The cells on the outside of our skin are old dead cells. New skin cells are right under the outside. These are the living skin cells. They work for our bodies. They help protect our bodies and heal cuts.

Our bodies make skin cells all the time. As the old cells fall off, new cells grow in the same place. Each person makes about 18 kg of skin cells during his or her life. Outside skin cells fit together closely with no gaps between them. When you cut yourself, you can harm your skin cells. A small cut will not be harmful. Your skin will quickly heal itself by making new skin cells. How do skin cells work? First, the cells near the cut get bigger and move into the gap. Next, these bigger cells meet in the middle. They form a new layer(层) of skin cells. Finally, new cells will grow until the gap disappears. In this way, your skin can grow and get well itself. How amazing the small cells are! Next time you have a cut, don't worry about it. Maybe in a few days, you will be surprised to find it healed.

1.The underlined word “gaps” in the passage means “______” in Chinese.

A．突起             B．条纹             C．缝隙             D．代沟

A．are large and we can see them with our eyes
