When you are curious about something and want to know more about it, you can use the way of asking questions. Asking questions is the first step to make discoveries and find interesting answers. The following steps can guide you during the research.
Step 1 Write down the subject that you are interested in on a piece of paper. Just get the main idea down. For example, you might write:
Discover more about robots.
Step 2 Stop and think for a moment about what you have already known about your subject. List what you have already known like the sentences below:
1. The first robot appeared in the USA in 1959.
2. A robot can do housework and act as a teacher.
3. Sometimes a robot catches viruses and causes a lot of problems.
Step 3 What can you do with what you want to learn? By asking questions, start writing down questions about the robots on the paper:
1. What might robots be like in the future?
2. What other things can robots do for people?
3. What kind of power will robots possibly use in five years?
Step 4 Armed with your list of questions, you can now go to the nearest library or computer to begin your research. As you learn more about your subject, you’ll probably discover some new questions.
For example, you might discover that robots can help scientists explore dangerous places, like the sea and outer space. How? What happened? Asking new questions can help you research your subject more widely.
The next time you find something interesting to research, take time to organize your thinking by asking good questions. And remember that learning more always brings more questions.
【小题1】What does the writer advise us to do when we’re curious about something?

When  people    travel    in  another  city  or   country ,they  sometimes  stay  in  the  homes of the local people.  This is called   homestay  .   It  is    a  great  experience  because  you  can  meet  people    from   a  different  country   or  city  and  learn  something  new  about   that  place   .                                                                                       I  am  Wan  Li  from  China.  I came  to  the  UK   with  my  friends  for  a  short   visit  .    we   are  living   with  an English  couple   ,Mr.   and  Mrs.Green  ,in  the  west   of    London.    They   have    a    wonderful      four –bedroom  house   .     This   is  a new   house  .  It   has    two   bathrooms     and  a   garden    with  many    beautiful    flowers.   I   have   a   bedroom    of   my   own   .                                                                                     
There  are   some    shopping    centres    and     restaurants     near     the    house,     and   the  house   is  close   to   an     underground  station. It  takes   about  thirty  minutes  to  get  to   the  centre  of  London. 
I  think   a  homestay   may  be   a  good   choice  for  you  if  it  is  your  first  time  to  visit  abroad .  The local  people  are  friendly  and  willing  to  help. If  you  happen  to  celebrate   the  holidays  with  them,  you  will  get  to  know  more  about    western  culture  and  customs.
