20．-Where's Mary？
-I'm not sure．She _________be in the reading room．
A．needB．mayC．must

分析 --瑪麗在哪里？
--我不確定．她可能在閱覽室里．

解答 答案：B．need需要；may可能；must一定，必須．根據(jù)I'm not sure，在這里表示不確定，表示可能性不大，may可能，在表示推測(cè)時(shí)不如must可能性大．故選B．

點(diǎn)評(píng) 本題考查了情態(tài)動(dòng)詞的用法．解答時(shí)注意：must表示推測(cè)時(shí)，可能性要比may大．

Humans eat the seeds （種子） of the grass．Rice is a special kind of grass that has big seeds，and they taste good!There are over 100different kinds of rice grown around the world．Over many years，humans have changed rice to have more and larger seeds，and it has become a very important food．After corn，it is the most popular seed in the world．It is the basic food for a large part of the world's population．
How often do you eat rice？We are eating it less often than we used to．We are now eating more bread and meat instead of rice．Even though we now eat less rice，rice is a very important part of life for many people around the world．Did you eat some rice today？

The dandelion is one of the most useful weeds．It is really a living supermarket．The leaves of the young plant are delicious．The leaves can also be cooked．With beans they make a nice meal．All parts of the plant can be used．Roots and leaves are often used in medicines．Have you ever tasted any dantelions？

B．Because its leaves can be cooked and taste delicious．
C．Because its roots and leaves are used in medicine．
D．Because all parts of the dandelion can be used．
