题目内容

3.Seed plants-plants _____ from seeds-need water,sunlight and mineral to grow vigorously.(  )
A.grownB.to growC.to be grownD.having grown

分析 种子类植物,一种用种子培养出来的植物,需要水,阳光和矿物质才会蓬勃生长的植物.

解答 答案:A
题干中grow是作plants的后置定语,要用非谓语动词;grow与被修饰名词构成动宾关系,要用被动;句意表达的是客观事实,不能用不定式.故选A.

点评 过去分词是非谓语动词的一种,用法很灵活,分为简单式done(表示与谓语同时或几乎同时发生的动作);完成式having been done(表示先于谓语的动作).学习时,要把握其用法特征:表示被动和完成.同时还要注意区分现在分词和不定式.

14.China is a land of bicycles.At least it was back in 1992when I traveled the country.Back then everyone seemed to be riding a bicycle.Millions of them,all black.Cars were rare.Yet since my arrival in Beijing last year,I've found the opposite is true.There are millions of cars.However,people still use their bicycles to get around.For many,it's the easiest and cheapest way to travel today.Bicycles also come in different colors-sivler,green,red,blue,yellow,whatever you want.
  It's fun watching people biking.They rush quickly through crossroads,move skillfully through traffic,and ride even on sidewalks(人行道).Bicycles allow people the freedom to move about that cars just can't provide.
  Eager to be part of this aspect of Chinese culture,I decided to buy a bicycle.Great weather accompanied my great buy.I immediately jumped up on my bicycle seat and started home.
  My first ride home was orderly (守秩序的).To be safe,I stayed with a"pack"of bikers while cars on the streets came running swiftly out of nowhere at times.I didn't want to get hit.So I took the ride carefully.
  Crossing the streets was the biggest problem.It was a lot like crossing a major highway back in the United States.The streets here were wide,so crossing took time,skill and a little bit of luck.
  I finally made it home.The feeling on the bicycle was amazing.The air hitting my face and going through my hair was wonderful.I was sitting on top of the world as I passed by places and people.Biking made me feel alive.
