Do you know they can tell us what the weather was like even hundreds of years ago? A tree will grow well in a climate with lots of sunshine and rainfall．And little sunshine or rainfall will limit the growth of a tree．We can see the changes of climate by studying the tree rings．For example，to find out the weather of ten years ago，count the rings of a tree from the outside to the inside．If the tenth ring is far from the eleventh ring，we're sure that it was sunny and rainy most of that year．However，if the tenth ring is near the eleventh ring，then the climate of that year was bad． Tree rings are important not only for studying the history of weather but also for studying the history of man．Many centuries ago there lived a lot of people at a place in New Mexico．But now you can find only sand but no trees，no people．What happened to that place? A scientist studied the rings of the dead trees there．He found that the people had to leave because they had cut down all the trees to make fires and buildings．As all the trees had gone，the people there had to move． (　C　)1．According to the passage，people can find out the changes of climate by studying ． A．sunshine B．rainfall C．tree rings D．tree leaves 解析：细节理解题。根据“We can see the changes of climate by studying the tree rings．”可知，人们可以通过研究树的年轮来发现气候的变化。故选C。 (　B　)2．The underlined word “limit” probably means “ ”． A．stop B．reduce C．help D．record 解析：词义猜测题。根据“And little sunshine or rainfall will limit the growth of a tree．”及常识可知，少的阳光和降雨会让树木生长得更缓慢，B选项“减少”与其意思相符。故选B。 (　C　)3．Which of the following statements is TRUE? A．Snow and wind will help the tree grow． B．We can only count tree rings from the inside to the outside． C．Tree rings can help us learn about the history of man． D．Tree rings are important for studying the history of food． 解析：细节理解题。根据“Tree rings are important not only for studying the history of weather but also for studying the history of man．”可知，树的年轮可以帮助我们了解人类的历史。故选C。 (　D　)4．According to the passage，people at the place in New Mexico left because ． A．they had no place to live B．there was too much pollution C．they had no food to eat D．there were no more trees for them 解析：细节理解题。根据“As all the trees had gone，the people there had to move．”可知，新墨西哥州的人离开是因为那里没有树木了。故选D。 (　B　)5．This passage is mainly talking about ． A．ways to study tree rings B．the importance of tree rings C．the climate and tree rings D．man and tree rings 解析：主旨大意题。根据“Tree rings are important not only for studying the history of weather but also for studying the history of man．”及全文内容可知，文章主要讲述了树的年轮对于气候和人类历史研究的重要性。故选B。 B Every living thing needs to reproduce．Reproducing means creating more members of your group．In order for plants to reproduce，they have to spread their seeds to other areas．Plants have developed all kinds of ways to do this． This simplest way is gravity．Many seeds are inside of fruit．When a piece of fruit gets too heavy，it falls from a tree to the ground．Sometimes animals will pick up the fruit and drop it in another area．That helps move the seed even farther away．Apples spread in this way． Other plants use wind to spread their seeds．Dandelions(蒲公英) are a good example of this．Dandelion seeds are so light that when wind blows，it carries dandelion seeds to new places．Maple(枫树) seeds also use wind．Their seeds are connected with long thin leaves that look like wings．When the seed falls from the tree，its “wings” help it fly farther from the tree． Some animals help plants spread their seeds．The animals eat the seeds．While the seed is in the animal's body，it stays whole．When the seed leaves the animal，it's in a new place． Ants also help spread seeds．Some seeds have a special smell that attracts(吸引) ants．The ants bring the seeds back to their home，which of course is underground．They only eat part of the seed．They leave the rest of the seed underground．After that，the seed can start growing． (　A　)6．The underlined word “gravity” in the second paragraph means “ ”． A．the force that causes fruits to fall to the ground B．the action that makes animals drop seeds C．the force that moves seeds even farther away 解析：词义猜测题。根据“Many seeds are inside of fruit．When a piece of fruit gets too heavy，it falls from a tree to the ground．”可知，果实里面有许多种子，当果实变得太重时，它会从树上掉到地上。结合常识可知，果实从树上掉落是因为重力。由此猜测，gravity意为“重力”，即“导致果实落地的力量”。故选A。 (　B　)7．How do maples spread their seeds? A．They use animals． B．They use wind． C．They use smells． 解析：细节理解题。根据“Maple(枫树) seeds also use wind．”可知，枫树通过风传播种子。故选B。 (　B　)8．According to the passage， is the correct order． a．The ants only eat part of the seed． b．The smell of the seeds attracts the ants． c．The ants carry seeds to the underground home． d．The ants leave the rest of the seed underground． A．b－d－a－c B．b－c－a－d C．b－a－c－d 解析：细节理解题。根据“Some seeds have a special smell that attracts(吸引) ants．The ants bring the seeds back to their home，which of course is underground．They only eat part of the seed．They leave the rest of the seed underground．”可知，事件的正确顺序是b－c－a－d。故选B。 (　B　)9．Which of the following is TRUE according to the passage? A．To spread their seeds，plants have to develop some kinds of ways to do this． B．With the help of the wind，the seeds of dandelions and maples are carried farther． C．The whole seed in the ant's body leaves them in the new places，and the seed starts growing． 解析：细节理解题。根据“Dandelion seeds are so light that when wind blows，it carries dandelion seeds to new places．Maple(枫树) seeds also use wind...When the seed falls from the tree，its ‘wings’ help it fly farther from the tree．”可知，在风的帮助下，蒲公英和枫树的种子被带到了更远的地方。故选B。 (　A　)10．What's the best title of the passage? A．How Plants Spread Seeds B．Why Animals can Spread Seeds C．How Wind Helps Seeds Spread 解析：最佳标题题。通读全文可知，本文主要介绍了几种植物传播种子的方法。因此，选项A“植物如何传播种子”是最佳标题。故选A。 C What will you say if you see a tree walking?

There are trees that really “walk”．These trees have long roots．The roots are like our legs when they grow out． Walking trees grow in Florida．It is warm there．(A)They like living there because they can get a lot of rain．They grow in and near water．Walking trees can grow in salt water(咸水)．Not many trees can grow with their roots in salt water． Some people say the walking trees look more like bushes(灌木) than trees．They do not grow very tall．The walking trees are hard and people can use them to make boats．Their flowers are small and yellow．Many fish and some large animals make their homes around the roots of the walking trees．(B)They don't need to worry about the trees' walking on them，because the walking trees don't walk very fast．One person watched a tree when it walked．The tree spent one year moving 3 m．It's a good thing because they don't have to walk very far． 根据短文内容，完成下列各题。 11．请将文中(A)处画线句子翻译成汉语。 它们喜欢生活在那儿，因为它们能得到很多雨水。 12．请在文中找出与“In some people's idea，walking trees aren't trees but bushes．”意思相同或相近的句子。 Some people say the walking trees look more like bushes than trees． 13．请根据文章内容，列举出walking trees的两条用途。 ① People can use them to make boats． ② Many fish and some large animals make their homes around the roots of the walking trees． 14．What does the underlined word “They” refer to?
