5．Do you know that          with wise men improves your mind？（　�。�
A．chatB．ChatsC．chattedD．chatting

分析 你知道與有智慧的人聊天會(huì)提高你的智力嗎？

解答 答案是D．本題考查動(dòng)名詞做主語(yǔ)．題干含that引導(dǎo)的賓語(yǔ)從句，賓語(yǔ)從句中謂語(yǔ)動(dòng)詞improve前的"chat with wise man"充當(dāng)主語(yǔ)；A和B都是謂語(yǔ)動(dòng)詞形式，不能做主語(yǔ)；C項(xiàng)無(wú)論是過(guò)去式還是過(guò)去分詞都不能做主語(yǔ)，所以排除A、B和C；本題用動(dòng)名詞chatting做主語(yǔ)，所以答案選擇D．

點(diǎn)評(píng) 對(duì)于非謂語(yǔ)動(dòng)詞的選擇，首先要根據(jù)句子的結(jié)構(gòu)判斷句中缺少的是謂語(yǔ)動(dòng)詞還是非謂語(yǔ)動(dòng)詞；如果是非謂語(yǔ)動(dòng)詞，在理解非謂語(yǔ)動(dòng)詞的基本用法的基礎(chǔ)上再根據(jù)句子的結(jié)構(gòu)做出判斷．

15．A recent study of ancient and modem elephants has come up with the unexpected conclusion that the African elephant is divided into two distinct（不同 的）species．
     The discovery was made by researchers at York and Harvard Universities when they were examining the genetic relationship between the ancient woolly mammoth and mastodon to modem elephants-the Asian elephant，African forest elephant，and African savanna elephant．
     Once they obtained DNA sequences（序列）from two fossils（化石），mammoths and mastodons，the team compared than with DNA from modem elephants．They found to their amazement that modem forest and savanna elephants are as distinct from each other as Asian elephants and mammoths．
     The scientists used detailed genetic analysis to prove that the African savanna elephant and the African forest elephant have been distinct species for several million years．The divergence of the two species took place around the time of the divergence of Asian elephants and woolly mammoths．This result amazed all the scientists．
    There has long been debate in the scientific community that the two might be separate species，but this is the most convincing scientific evidence so far that they are indeed different species．
    Previously，many naturalists believed that African savanna elephants and African forest elephants were two populations of the same species，despite the elephants'significant size differences．The savanna elephant has an average shoulder height of 3.5 metres while the forest elephant has an average shoulder height of 2.5 metres．The savanna elephant weighs between six and seven tons，roughly double the weight of the forest elephant．But the fact that they look so different does not necessarily mean they are different species．However the proof lay in the analysis of the DNA．
     Alfred Roca，assistant professor in the Department of Animal Sciences at the University of Illinois，said，"We now have to treat the forest and savanna elephants as two different units for conservation purposes．Since 1950，all African elephants have been conserved as one species．Now that we know the forest and savanna elephants are two very distinctive animals，the forest elephant should become a bigger priority（優(yōu)先）for conservation purposes．"
46．One of the fossils studied by the researchers is that ofD．
A．the Asian elephant                       B．the forest elephant
C．the savanna elephant                     D．the mastodon elephant．
47．The underlined word"divergence"in Paragraph 4 means"C．"
A．evolution      B．exhibition             C．separation       D．examination
48．The researchers'conclusion was based on a study of the African elephantsA
A．DNA        B．height                 C．weight          D．population
49．What are Alfred Roca's words mainly about？A
A．The conservation of African elephants．
B．The purpose of studying African elephants．
C．The way to divide African elephants into two units．
D．The reason for the distinction of African elephants．
50．Which of the following can be the best title for the passage？C
A．Naturalists'Beliefs about Elephants
B．Amazing Experiments about Elephants
C．An Unexpected Finding about Elephants
D．A Long Scientific Debate about Elephants．

12．Towards evening，Jennifer was walking on the beach with a gentle breeze blowing through her hair．Looking up at the golden red sun ball，she was surprised by its color，deep red in the middle，softly fading into yellow．She could hear nothing but the waves and the seagulls flying up above in the sky．
The atmosphere relaxed her．This was what she needed．"It's getting late，"she thought，"I must go home．My parents will be wondering where I am．"She wondered how her parents would react when she got home after the three days she was missing．She kept on walking，directing herself to bungalow（平房）163，where she spent every summer holiday．The road was deserted．She walked slowly and silently．Just in a few hundred meters，she would have been safe in her house．
It was really getting dark now．She wished she had her favorite coat on．It might keep her really warm．She imagined having it with her．This thought dissipated（消散） when she finally saw her front door．It seemed different．Nobody had taken care of the outside garden for a few days．She was shocked：her father was usually so strict about keeping everything clean and tidy，and now…

It felt so good being back home．Suddenly she heard a voice．"Are you feeling better now，dear？You know you got us very，very scared．"

28．The author mentions the views of the beach in Para.1in order toB．

9．Junk is everywhere，even in space．But getting rid of space junk is much harder than simply cleaning your bedroom．Space junk travels at 8 kilometers a second，according to an article in the Guardian．Catching it is a bit of a challenge．
     Luckily，scientists at the Swiss space center have a new cleaning plan．Theyare about to send a"cleaner satellite"into space within the next five year？．It will clean up space junk，according to a report in the Guardian．
     Named"Clean Space One"，the Swiss satellite finds its target and moves close to it．When it reaches its target，it will catch the junk with a gripping claw （抓手）．This is not going to be an easy task because both the satellite and the junk are traveling so fast．
     Once Clean Space One has caught the junk，all it has to do to get rid of it is to fly back to Earth．This is because the junk will bum up when traveling through the atmosphere．The satellite itself will burn up a'，the same time．
     Ever since people started to send objects into space more than 50 years ago，there has been junk in space．Junk on Earth like food wrappers （包裝紙）or waste paper is also a problem．But space junk is mainly made up of exploded rockets and broken satellites．If no one cleans them away，they just keep traveling around Earth．
     So far，NASA has found 16.000 pieces of junk that are larger than 10cm in diameter（直徑）and more than 500，000 pieces measuring between 1cm and 10cm．You can imagine how many even smaller ones there are in space．
     Space junk is dangerous for spacecraft （飛船） and the International Space Station．Even a very small piece could seriously damage-or even destroy-a satellite or space-craft if it collided （碰撞） with the junk．The International Space Station has to regularly change its orbit to avoid space junk，
     Space junk might also be a danger to humans．During the last four months，three very large spacecraft have fallen to Earth．Fortunately，no one was hurt because the junk landed in the ocean．
45．According to the article，space junkD．
    A．travels at the same speed as satellites
    B．could be cleared away within five years
    C．travels at 8 kilometers per hour
    D．will cause a lot of trouble to space stations
46．What will happen to the space junk if it is not cleaned up？C
    A．It will explode in a few years．
    B．It will drift away from Earth eventually．
    C．It will keep traveling around Earth．
    D．It will gather and become a large mass．
47．Which of the following is TRUE about a"cleaner satellite"？B
    A．The junk is dealt with after it reaches Earth．
    B．Catching space junk is difficult for a satellite．
    C．The'satellite can catch several pieces of junk at once．
    D．The satellite goes back to space after it has finished its task．
48．Which of the following statements is TRUE？A
    A．The history of space junk dates back 50 years．
    B．Space stations travel in the same orbit as the junk．
    C．Space junk is harmless to people on Earth．
    D．It's impossible to stop space junk from colliding with spacecrafts．
