【题目】It may seem easy to say that plants and animals are different. Any child can tell the difference between a tree and a dog. But those differences are far deeper then just what they look like. The cells (细胞) that plants are made up of are different. In other words, the cell wall of plants has something special.

First of all, it’s important to find that not all plant cells have a cell wall. Besides, there are many differences of a cell wall based on the kinds of plant. The following is meant to be what a plant cell wall is like.

The cell wall of a plant is on the our side of the cell membrane (膜). It is usually hard and cannot be bent easily, but the degree of flexibility (韧性) of the cell wall is different. It is based on the special use that the cell has in keeping the plant alive. Cells that make up the trunk of a tree are clearly less flexible than cells on a leaf.

Cell walls act in many ways. They serve to protect the plant. They provide support, as well as help in the movement of chemicals and wastes into and out of the cell. More importantly, they control the water that goes in and our. Plants must have good water controlling systems (系统), allowing them to keep water during dry seasons, and get rid of unnecessary water. Plants can’t walk around to find water, so being able to control water is very important.

【题目】Even though she’s quite young, Drew Barrymore can be a Hollywood legend (传奇). She was born on February 22, 1975, in California. Being from a family that produced great actors, she quickly found her way into the spotlight (聚光灯).

When she was 11 months old, she made her first advertisement on TV. She made her first movie at the age of 2. Five years later, she acted Gertie in Steven Spielberg’s famous film E.T. the Extra-Terrestrial(1982).

However, it wasn’t all roses and sunshine when Barrymore was growing up. She was drinking wine by the time she was 9, smoking marijuana (大麻) at 10.

Most kid stars in Hollywood fail to become stars as adults. And most of the time, once they’re out of the spotlight, they stay out. But Drew Barrymore doesn’t.

As she was growing older, Barrymore started to realize that life is more meaningful than dangerous actions in the films. She started to build a career in 1997. She has made a series of successful films since then, including Charlie’s Angels (2000) and 50 First Dates (2004).

“In my life, there is darkness and drama, and I have yet to explore some of that in my work life. I just want to challenge (挑战) myself and prove that I can do more.”

Actually, anyone who’s not familiar with her disordered childhood might find it hard to believe she’s such a sweet person now. Like many of the characters she plays in her comedy, Drew is easy-going and laughs a lot. In 2007, she was on the cover of People magazine’s 100 Most Beautiful People issue.

“Life is very interesting in the end, some of your greatest pains, become your greatest strengths,” Drew said.
