 Is there a chocolate-powered racing car in the world? Hey! You have read too (A)________ children's books! But wait! Now，there is really such a racing car in the world．A team from a British university made it．

         The chocolate-powered racing car's engine(发动机) uses waste from chocolate factories or vegetable oil as fuel (燃料)．Its body (B)用土豆制成，its steering wheel is made from carrots，its seat is made of soybeans，(C)________its brake pads(刹车片)are made from nuts! Well，can this car run very fast?  (D) Certainly! It can go from zero to 60 miles per hour in 2.5 seconds，and go as fast as 135 miles per hour．When the racing car is running，it cleans itself and lets out oxygen．

  “It took us more than nine months to (E) complete the racing car，”said a team member．“The car is really green． You can find many of the car's parts at a farmer's market or even in a litter bin because most of the materials(材料) are waste in most people’s eyes．It’s fun．”

However，(F)this eco-friendly  (环保的) car cannot be driven in the official(正式的)race because of the engine's unusual fue.

1.在文中(A)和(C)的空白处分别填入适当的词 ________ ________

2.将文中划线部分(B)译成英语：________

3.写出文中划线部分(D)和(E)的同义词语或近义词语：________ ________

4.将文中划线部分(F)改写为：the engine's unusual fuel makes it________ to________ this eco-friendly car in the official race

5.从文中找出能说明本文中心大意的短语：________
