We talk every day. When we have good news, we like to share it with our good friends and when something terrible happens, we make it known to others soon. But can you imagine that a tree can talk and share hews too? Of course, no tree moves lips and says words just as people do. Strange as it may sound, though, some trees do manage to communicate with each other.
Willow(柳樹) trees are the best-known of these trees. When insects(昆蟲) begin nibbling(叮咬) a willow tree, the tree sends out a special smell at once. This smell tells the other willows that harmful insects are coming near. All of them quickly make a chemical(化學(xué)物質(zhì)) in their leaves. This chemical is bad to the insects. The insects do not like it and they fly away soon. In this way, the willow trees protect themselves from the insects.
The next time when you take a walk in the woods, maybe the trees are “talking” to each other quietly. And when someone says that trees cannot “talk”, please tell them that even trees give messages to each other, too.
小題1:Willow trees send messages with _________.
A．wordsB．movementsC．smellsD．sounds
小題2:the underlined word “lips” in the first paragraph means ________.
A．樹干B．嘴唇C．枝條D．手勢(shì)
小題3: The passage tells us that some of the trees can ________.

c. Insects fly a way because of the chemical.
d. Insects begin nibbling a willow tree.
A．d-a-b-cB．d-b-a-cC．a(chǎn)-b-c-dD．d-c-b-a

You may know about “ junk food” like French fries. But do you know about “junk sleep”?
Recently, a British survey found that electronic(電子) products in teenagers bedrooms are affecting(影響)their sleep.
