五、阅读短文,在文中空白处填入1个适当的单词,或用括号内所给单词的正确形式填空。
Lucy and Lily are British girls. They are twin(双胞胎) sisters. They look 
the
 same. They are in the same school but in different 
classes
. So we often mistake Lucy for Lily or mistake Lily for Lucy. But it's easy for 
their
 mum to tell the differences. The two girls like the same clothes, but they like different 
colours
. For example, they both like skirts and sweaters. Lucy's favourite colour is blue, but Lily 
likes
 green best. Her skirt is green, and her sweater is green, 
too
. They like books. They often borrow(借) books 
from
 the library of the school. Their mother asks them 
to do
 sport every day. Lily is good at basketball and Lucy does 
well
 in baseball. They think playing sport is 
interesting
. Do you like them?
