2. try to use the proper conjunctions.
3. refer to the chart while retelling.
4. the possible version below can be used as a material for both retelling and dictation.
one possible version:
 i’m yuan longping. look at my sunburnt face and arms and my slim, strong body and you will think i’m more like a farmer than a scientist. in fact i have struggled for the past five decades to help farmers. in 1974, i began to grow a so-called super hybrid rice. this special strain of rice makes it possible to produce one-third more of the crop in the same fields.
 i was born into a poor farmer’s family in 1931. when i was young, i saw many people go hungry often. so i have devoted myself to finding ways to increasing rice harvest without expanding the area of fields since i graduated from southwest agriculture college in 1953. now more than 60 % of the rice produced in china each year is from this hybrid strain. i am circulating this knowledge in india, vietnam and other less developed countries to increase their harvest. perhaps you think i am rich. actually i live a simple life. i care little for money. in my opinion a person with too much money will have more troubles. i don’t want to be famous because i prefer to have more time to do my research. in my free time i love listening to music, playing mah-jong and reading. i once had a dream, in which i saw rice plants as tall as sorghum and each ear of rice was as big as an ear of corn and each grain of rice was as huge as a peanut. now i have another dream—to export my rice so that it can be grown all over the world.
