Have you ever recorded information about your everyday activities by means of a smartphone？Perhaps you've tracked（追蹤）how many kilometers you've run，how many hours you've slept or how many calories you've burned in a day.
   If so，you've taken part in a movement called the"Quantified Self Movement"，also called self-tracking.The idea is to take information about your everyday activities and analyze them to help form a healthier lifestyle.
   Tracking daily activities isn't a new idea.In past years，athletes and their coaches kept notes detailing nutrition，training and sleep patterns in order to achieve an athletic goal.Similarly，doctors have also helped patients to record parts of their life styles and eating habits to help fight allergies（過敏），headaches and other health problems.However，it wasn't until 2007 that magazine editors Gary Wolf and Kim Kelly，who started tracking every move they made，invented the term"Quantified Self"Wolf says that self tracking will change our sense of self with the purpose of making us more effective in the world.
   Self-tracking is becoming a lot more popular these days，as it becomes easier for people to use modern technology tools to track what they're doing and share it with others.Recently，tools such as smartphones，journals and apps，along with newly published wearable things can help record personal data including sleeping hours，stress levels，heart rate，mood and soon.With these tools，self-tracking can help us recall our behavior with greater accuracy（精確）and see ourselves more clearly.
  Although people benefit a lot from self-tracking，Dennis Nash，president of Data Speaks Health Solutions，says self-tracking has its drawbacks.Once people start tracking their daily activities，it can become an addition people like to do often.Also，they might begin to worry too much about their health.
   While self-tracking doesn't guarantee（保證）that one's quality of life will improve，it can stress the importance of eating well and exercising daily.After all，the Quantified Self Movement's focus is motivating（激勵）people to apply enough energy to make healthier choices.

2．Height is just one of the thousands of 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．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（潛力）．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 two inches（six centimeters） a year between age three and the time when they start puberty．
Your doctor will know how your growth has been going over the years．Two centimeters here and two 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 nervous 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．

3．Can anyone be an astronaut？
   Of course not.You don't have to have a science degree but most astronauts do.Most of them are pilots too.Life in a spaceship is hard so you must have a healthy body and mind.You need to be easy-going，patient，and helpful to spend so much time in a small space with other people.
   What's the training like？
   People have to train for a year to learn how to stay healthy and safe.They practise space walking and living in zero gravity（重力）.They train in difficult conditions to learn how to solve problems and to work in a team.Everyday tasks like eating，washing and sleeping can be difficult on a spaceship.There is no running water so you have to wash with wet tissues：it's hard to enjoy the dry food that astronauts have to eat.And to sleep you must cover your eyes because the sun rises every 90 minutes on the International Space Station.You also have to tie yourself to something so you don't fly away!
   What health problems do astronauts have？
   Life in zero gravity causes changes to our bodies.Bones and muscles（肌肉）become thin and weak so you must do a lot of exercise in space to stay fit and to help the heart move blood around your body.Astronauts often get backache because you grow in space— up to 8 centimeters!It's also common to have headaches and to feel sick，especially at the beginning.You must have vitamins to take the place of fresh fruit and vegetables.But you don't have to put on sun cream because space suits can protect your skin （皮膚）.

A．A science degree.
B．A pilot's license.
C．A healthy body and mind.

B．Why young people are interested in space trips？
C．What problems astronauts must solve in space.
