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 surface (表面) 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 ( 复原,治愈) 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 18kg of skin cells during his or her life. Surface skin cells fit together closely with no gaps between them. When you cut or burn yourself, you can harm ( 伤 害 ) your skin cells. A small cut will not do much harm. Your skin will quickly heal itself by making new skin cells in just some days. 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 completely. In this way, your skin can grow and get well itself.

How amazing the tiny cells are! Next time you have a cut, don’t worry about it. Maybe in a few days, you will find it healed.

Introduction	Small cuts in the skin can heal themselves in a1.days.
Causes	Two kinds of skin2. The cells on the skin are3.and dead. The living cells4.the surface are pretty new, so they work for 5. our bodies. 6.to work Surface skin cells are7.to each other. When they’re cut or burnt, the cells nearby will become 8.and move into the gap. Then they9. in the middle and form new skin cells. At last, new cells will grow until there’s no gap.
Conclusion	If your skin has a cut, don’t be10.because it will heal itself some days later.

【解析】

这篇短文主要讲述了地球上的每一个生物都是由细胞组成的。我们的身体一直在制造皮肤细胞。当旧细胞脱落时，新细胞在同一个地方生长。文中介绍了皮肤细胞是如何工作的。

1.

根据文中“Your skin will quickly heal itself by making new skin cells in just some days.” 你的皮肤会在几天内通过制造新的皮肤细胞而迅速自我修复。in just some days相当于in a few days在几天之后。a few加名词复数；故答案为few。

2.

根据“The cells on the surface (表面) of our skin are old dead cells. New skin cells are right under the outside. These are the living skin cells.” 我们皮肤表面的细胞是老的死细胞。新的皮肤细胞就在外面。这些是活的皮肤细胞。可知，The cells on the surface (表面) of our skin are old dead cells. New skin cells are right under the outside. These are the living skin cells.Two kinds of skin cells两种皮肤细胞。cell细胞，这里用复数形式，故答案为cells

3.

根据文中“The cells on the surface (表面) of our skin are old dead cells.” 我们皮肤表面的细胞是老的死细胞。The cells on the skin are old and dead. 皮肤上的细胞是老的，和死的。故答案为old。

4.

根据文中“New skin cells are right under the outside.”新的皮肤细胞就在外面。皮肤表面下的活细胞很新。under在……下面；故答案为under。

5.

根据文中“These are the living skin cells. They work for our bodies. They help protect our bodies and heal ( 复原,治愈) cuts.” 这些是活的皮肤细胞。他们为我们的身体工作，保护身体。故答案为protecting。

6.

根据文中“Your skin will quickly heal itself by making new skin cells in just some days. 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 completely. In this way, your skin can grow and get well itself.” 你的皮肤会在几天内通过制造新的皮肤细胞而迅速自我修复。皮肤细胞是如何工作的？首先，切口附近的细胞变大并进入间隙。接下来，这些更大的细胞在中间相遇。它们形成一层新的皮肤细胞。最后，新的细胞会生长直到间隙完全消失。这样，你的皮肤就可以长得健康。可知，这里是说细胞是怎样工做的；这里是how引导。故答案为How。

7.

根据文中“Surface skin cells fit together closely with no gaps between them.” 表面皮肤细胞紧密地结合在一起，没有间隙。可知，这里是are close to…接近……；故答案为close。

8.

根据文中“First, the cells near the cut get bigger and move into the gap.”可知，首先，切口附近的细胞变大并进入间隙。中是变大，big的比较级是bigger。故答案为bigger。

9.

根据文中“Next, these bigger cells meet in the middle. They form a new layer (层) of skin cells.” 然后更大的细胞在中间相遇，形成新的皮肤层。meet相遇，集合。故答案为meet。

10.

根据文中“Next time you have a cut, don’t worry about it. Maybe in a few days, you will find it healed.” 下次你有伤口的时候，别担心。也许过几天，你就会发现它痊愈了。这里是不用担心。don’t be worried不用担心。worried形容词，担心的。故答案为worried。
