I stood in the doorway, watching my elder brother carefully putting clothes into his bag. I coughed uneasily. Finally   36   that I was there, Rocky turned towards me with a sad smile.
“I’m   37   tomorrow,” he said.
“I know.” My __38____ was almost a whisper. I was   39   at myself for being so weak, but I wasn’t about to cry.
“My   40   is early, so there is still   41   time to come to the airport,” he said. Seeing the   42   look on my face, he quickly added, “I promise I won’t leave without saying goodbye.”
I tried to say   43   , but didn’t. It’s always   44   to keep quiet if you’re about to cry. “You promised you wouldn’t cry,” he said to me, thinking that I was close to   45  .
I remember the day he taught me how to ride a bike.   46   I thought he was always right behind me, holding the seat to keep me from   47  . I was happy with this, but he knew he couldn’t hold me up all my life. He told me that one day he would have to let go.
His coughing stopped my thinking. What was left to say? How could I say   48   to the person who taught me everything?
The next morning I   49   , looked at my alarm clock, and realized he had left 50  ago. We never even said goodbye.
Goodbye, Rocky! Although he may have been many miles away, I knew he heard me, even if it was only an answer in his heart.

Do you know why different animals or insects have their special colors? Colors are used mainly to protect themselves.
Why can’t some birds easily catch locusts(蝗虫)? It is because locusts change their colors together with the change of the colors of crops. When crops are green, locusts look green. But as autumn comes, locusts change to the same brown color as crops have. Some other insects with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives in the day and appear only at night.
If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals can’t be easily seen by hunters. This is because they have the colors much like the trees.
Have you ever noticed an even more strange thing? A kind of fish in the sea can send out black liquid when it faces danger. While the liquid spreads over, its enemies can’t find it. And it quickly swims away. So it has lived up to now though it is not strong at all.

  Height is just one of the thousands of features your genes decide. In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then most probably you will be tall, too, but if you have questions about how tall you're going to be, ask your doctor if he or she can help you find it out.
But genes don't decide everything. For example, eating an unhealthy diet can keep you from growing to your full potential(潜力). Getting plenty of sleep and enough exercise will help you grow to the expected height.
No doubt you're wondering how fast you should grow. It depends. There's no perfect or right answer. Generally speaking, kids grow about 2 inches (6 centimeters) a year between age 3 and the time when they start puberty (when your body starts changing and becoming more grown up).
Your doctor will know how your growth has been going over the years. Two centimeters here and 2 inches there are not nearly as important as the height you're at now, how you've been growing up to this point, and what other changes your body may be going through.
Don't be scared if you seem to have grown a lot in a very short time. Everyone has a growth spurt(高峰)during puberty. The age for starting puberty is about 10 for girls and about 11 for boys. But it can be earlier or later ----between 7 and 13 for girls and 9 and 15 for boys.
You'll usually begin to notice that you're growing faster about a year or so after your body starts to show the first changes of puberty.

A.how the genes work in your bodyB.when is the time you grow fast
C.why you look like your parentsD.how you grow to a certain height
【小题4】 After reading this passage, we can explain          .
A.how good it is to be a doctorB.how much sleep time we need
