It is a special cross-country race. The competitors’ vehicles are made     1     fruits and vegetables like carrots, eggplants, grapefruits, pumpkins and oranges. They are the creations of pupils from the Shanghai World Foreign Language Primary School.

According to Chen You, the science class teacher,     2     (base) knowledge had been taught within 6 classes to students before they drew sketches and     3     (choose) vegetables to make a food car.

Although students were encouraged     4     (design) their cars together with parents, all the cars should be made in the class. After     5     (bring) piles of ingredients as well as tools the children began their innovation. Some cut the carrot slices to make them round, and some others assembled (组装) their car components together.

In addition to the     6     (compete), students are required to reflect on the     7     (difficulty) they encountered making their vehicles,     8     things they have learned from the activity and the improvements they think the course can make.

    9     touched the teachers most was the unity and friendship among the children. For example, although the contest was fierce (激烈的), students felt     10     (excite) for the champion car as if they themselves had stood out, and when a girl’s car fell apart their friends comforted her and helped reassemble the car.
