Height is just one of the features your genes (基因) 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 them 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.
It’s natural that you’re wondering how fast you should grow. There’s no perfect or right answer. Generally speaking, kids grow about 6 cm a year between age 3 and the time when they start puberty.
Your doctor will know how your growth has been going over the years. 2 cm here and 3 cm there make a little difference to the height you’re at now. How have you been growing up to this height? What other changes may your body be going through?
Don’t be amazed 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 after your body starts to show the first changes of puberty.
If you want to know how tall you should grow, _______.
| A．you should have enough exercise |
| B．you can record your growth during puberty |
| C．you should take some special medicine |
| D．you can ask doctors for help |
The Chinese for the word “puberty” is _______.

Nadia Comaneci，a famous gymnast （体操运动员），was born in Romania in

Everyone was surprised．There wasn't a sound for a moment．Then a voice came，"Ladies and gentlemen，Nadia Comaneci…10!"
The audience（观众）cheered very loudly．So what happened？Well，when the scoreboard was built，no one thought a score of 10.00 was possible．The decimal point （小数点）was in the wrong place!In fact，the scoreboard only had three digits（数位） to show scores，such as 9.50 or 9.85 at that time．

Bike﹣sharing has swept across China，with an increasing number of people choosing bike riding instead of driving．The bike that the service company provides has GPS or Bluetooth on it，and those bikes can be easily unlocked with a smart phone and left anywhere in public．Bike﹣sharing allows people to borrow a bike from one place and return it at another place easily．
In some cities，we can see more and more people riding this kind of sharing﹣bikes．It's very convenient to use the bikes if you have a smart phone．First，you have to download such an APP on your smart phone．Then what you need to do is to find a nearest bike through the APP，scan the QR code on the bike or connect your phone with the bike over a Bluetooth wireless connection．You will find the bike can be unlocked itself．Then you can enjoy your trip．What's more，the greatest advantage of bike﹣sharing is that you can easily find one and never worry about where to park it．The cost of riding depends on the time that you spend．Normally，every hour you ride，you need to pay one yuan．It doesn't cost so much，does it？
At the same time，some people park the bikes in their own homes．Besides，some people don't value the bikes．Now service companies are trying to solve the problem like being stolen．

Have you ever wondered how we know the things that we know？ How do we know， for example， that the stars are really huge balls of fire like the Sun and very far away？ And how do we know that the Earth is a smaller ball turning round one of those stars， the Sun？
The key to these questions is "evidence"， which means the facts， signs or objects that make you believe something is true．
Sometimes evidence means actually（实际地） seeing（or hearing， feelings， smelling …） that something is true． Astronauts have travelled far enough from the Earth to see with their own eyes that it is round． Sometimes our eyes need help． The "evening star" looks like a bright twinkle in the sky， but with a telescope（望远镜） you can see that it is a beautiful ball． Something that you learn by direct seeing（or hearing or feeling …） is called an observation．
Often evidence isn't just observation on its own， but observation always hides at the back of it． If there's been a murder， often nobody（except the murderer and the dead person!） actually observed it． But detectives can gather together lots of other observations which may all point towards the suspect． If a person's fingerprints match those found on a knife， this is evidence that he touched it． It doesn't prove that he did the murder， but it can help when it's joined up with lots of other evidence．
Prediction（预测） helps to look for evidence． Scientists make a guess about what might be true． For example， if the world is really round， we can predict that any of us， going on and on in the same direction， should eventually find ourselves back where we started．
People sometimes say that you must believe in feelings deep inside， but not all the inside feelings are real evidence．
What can we do about all this？ When somebody tells you something that sounds possible， think to yourself： "Is there any evidence for that？" And， next time somebody tells you that something is true， why not say to them： "What kind of evidence is there for that？" Remember， always think carefully before you believe a word．
32． Which of the following is TRUE according to the passage？
A： What you see directly is real evidence．
B： Prediction helps to prove something if it is true．
C： People should always believe their inside feelings．
D： Astronauts find the Earth is round with a telescope．
33． Why does the writer use the example of a detective in Paragraph 4？
A： To explain what prediction is．
B： To tell what observation is called．
C： To introduce how detectives work．
D： To prove evidence is not just observation．
34． The underlined word "eventually" in Paragraph 5means ．
A： finally
B： probably
C： completely
D： luckily
35． What's the best title of the passage？
A： Evidence speaks
B： Scientists make predictions
C： Inside feelings help get ideas
D： Observation offers the facts
