My brother is ____ ____ his homework.

    Do you know how to study in a right way?The following are the ways of studying．

    First，the best time for reading is morning，because in the morning，the air is fresh and the mind is clear．For that reason，we can get good result．

    Second，in studying we must have patience．If we have not known a text well，we must read it again．We should not read the next one until we have learned the first one．

    Third，when we are studying，we must put our hearts into the book，or we can get nothing from the book while we are reading．

    At last，we must always ask“whys”．If we don't understand something well，write it down and ask our teachers or our parents for help．In any possible way,we must know it completely and what we've learned can be used well and made better.

    Though there are many ways for studying，yet the above mentioned will be quite enough if we can keep them in heart and do so．
