Each cell in the human body contains about 25,000 to 35,000 genes, which carry information that determines your traits. Traits are characteristics you inherit from your parents; this means your parents pass some of their characteristics on to you through genes. For example, if both of your parents have green eyes, you might inherit the trait of green eyes from them. Or if your mom has freckles, you might inherit that trait and wind up with a freckled face. And genes aren’t just in humans — all animals and plants have genes, too.

Genes hang out all lined up on thread-like things called chromosomes. Chromosomes come in pairs, and there are hundreds, sometimes thousands of genes in one chromosome. The chromosomes and genes are made of DNA, which is short for deoxyribonucleic acid.

Chromosomes are found inside cells, the very small units that make up all living things. A cell is so tiny that you can only see it through the lens of a strong microscope, and there are billions of cells in your body. Most cells have one nucleus. The nucleus, which is sort of egg-shaped, is like the brain of the cell. It tells every part of the cell what to do. How does the nucleus know so much? It contains our chromosomes and genes. Tiny as it is, the nucleus has more information in it than the biggest dictionary you’ve ever seen.

第二节  读写任务(共l小题,满分25分)

       阅读下面的短文,然后按照要求写一篇150词左右的英语短文。

We Have Different Ideas!

This may be the most important choice—the turning point in my life.  Never before have I been so serious.  For me, a Senior Three student, which university to choose is really a hard question, especially when I hold a completely different opinion from my parents. 

I’m longing for Beijing University for its long history, beautiful campus and academic atmosphere.  Besides, it’s a good chance to experience a different culture. 

But to my great surprise, when my parents heard this, they are strongly against my idea.  Moreover, I was shocked to find mum crying! She asked in tears, “Why don’t you stay in Guangzhou? So young a girl, how can you take good care of yourself? Beijing, oh! It’s too far away.  What if I want to see you or you want to see me?” My father also asked me a serious question, “Are you sure you can find a good job in Guangzhou after graduation?”

Actually, I’ve thought about all these.  As an independent and active girl, I certainly can handle all the problems.  I insist on my choice, but I really value my parents’ agreement.
