Unit 5　 Looking into nature
单元读写训练
A.回答问题
请阅读下面短文,根据所提供的信息,回答五个问题。要求所写答案语法正确、信息完整切题。
In the past, scientists didn’t know that trees could sense things.Now, they discover that trees can notice lots of things around them!
Trees can feel the four main periods of the year.They know when to drop their leaves in autumn, and when to grow new leaves in spring.
Trees can sense light.They know where the sun is, so their branches grow in that direction.That’s why trees in the Northern Hemisphere (半球) usually have more branches growing out on the south side.
Trees can recognize insects.If an insect starts eating a tree of a certain species, the tree has clever ways of fighting back.For example, if an insect is eating the trunk of a pine tree, the tree can produce a glue-like liquid (液体), and use it to catch the insect.
Trees can sense directions.They can feel where “up” and “down” are.There is no light under the earth, but the roots always know which way to grow.
Tree roots can also sense sounds.They really like the sound of running water when they are thirsty.If the sound continues for a long time, the roots will slowly start growing towards it.
There are still many things we don’t know about trees.Scientists are working hard to find out more.
1.How many things that trees can notice are mentioned in the passage
______________________________________________________________2.Why do more branches grow out in the direction of the sun
______________________________________________________________3.How can a pine tree catch an insect eating its trunk
______________________________________________________________4.Why do the roots know which way to grow
______________________________________________________________5.What sound do tree roots like when they are thirsty
______________________________________________________________
Five/5.
Because trees can sense light.
By producing a glue-like liquid and using it to catch the insect.
Because trees can sense directions.
The sound of running water.
