Imagine yourself in a test situation.You are sitting there hesitating between two choices-A or C.
   Your instincts tell you that A is right but you think that C makes more sense.When you get your paper back you find out that A was correct and you regret not picking it，and you think，"I should have followed my instincts（本能）".
   Most of the time we think our instincts are not as reliable as facts but scientists have just discovered that our instincts are surprisingly powerful tools，according to the study published in the journal Proceedings of the National Academy of Sciences.
   Instincts don't come out of nowhere.When we make decisions，we weigh up the strengths and weaknesses of each choice.But when we make our choices based on our instincts，we actually go through the same process without realizing it. "A lot of our decision-making and a lot of our feeling are based on things that we're not really aware of，"said Sarah Moore，professor in University of Alberta，Canada.
   In order to find out how accurate people' s instinct can be，Professor Marius Usher of Tel Aviv University in Israel and his team designed an experiment to test it.
   In the experiment，people who were shown pairs of numbers on a computer screen，two pairs at a time.They were then asked to choose which of the two pairs of numbers had the highest average.But the fact is that the numbers changed so quickly that they were unable to memorize the numbers or do the math.They had to depend only on their instincts to make decisions.
   Scientists found something amazing as the experiment went on﹣the people's accuracy increased when they were shown more pairs of numbers.When shown six pairs of numbers the people chose correctly 65 percent of the time.But when they were shown 24 pairs，the accuracy rate grew to about 90 percent.
   "Intuitively，the human brain is able to take in many pieces of information and decide on an overall value"said Usher.
   Next time，when you are having a difficult time making decisions simply follow your instincts.
   There is a good chance that they will help you make the right choice.

A
.
A．point out making the right choices is often difficult
B．get us to think about whether our instincts are usually right
C．tell us to think over everything before making a decision

A．one pair of numbers was shown quickly each time

C．people gradually understood the rules of the numbers shown
D．people made more accurate choices when they were tested with more numbers
（4）Which of the following statements is TRUE？
D
D

A．The human brain has a limited ability of solving math problems.
B．The less you use your instincts，the more accurate they become.
C．People don't weigh up the strengths and weaknesses of things when they make choices.

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）.
   Are you still interested？
（1）What is a must for an astronaut？

A．A science degree.
B．A pilot's license.
C．A healthy body and mind.
D．A weak character.
（2）What must you do to prepare for a space trip？

A．Experience zero gravity.
B．Wash with running water.
C．Practise long walks.
D．Sleep with your eyes open.
（3）Why do astronauts have to exercise in space？

A．To make their bones and muscles thinner.
B．To help the heart work well and keep fit.
C．To avoid backache and grow much taller.
D．To stop their skins from getting sunburned.
（4）What is the text maily about？

A．What we need to know to become an astronaut.
B．Why young people are interested in space trips？
C．What problems astronauts must solve in space.
D．Why we need to train hard before a space trip.
