8．---Tommy is planning to buy a car．
---I know．By the time he returns from abroad，he ________ enough for a used one．（　　）
A．will have savedB．savesC．had savedD．will save

分析 --Tommy打算買輛車．
--我知道．當(dāng)他從國外回來的時候，他將能夠攢夠買一輛二手車的錢．

解答 答案：A．
根據(jù)句中的時間狀語By the time he returns from abroad可知，指的是截止到將來某個時間點發(fā)生的動作，所以使用將來完成時；will have saved是將來完成時，用來表示在將來某一時間以前已經(jīng)完成或一直持續(xù)的動作．故選A．

點評 本題考查將來完成時，表示截止到將來的某個時間點已經(jīng)完成的動作，做題時，要把握句中時間狀語by the time you visit us in New York這一特點，結(jié)合句意，選擇正確的時態(tài)．

18．Zero gravity looks cool．But what about the thing no one likes to talk about？Yes，that is right：going to bathroom．Zero gravity makes this everyday task quite a challenge．Astronauts have to be toilet-trained all over again．
The Apollo astronauts raised themselves off the seat of their chairs and stuck a clear plastic bag to their back sides with sticky strips．A second astronaut watched closely to be sure no waste matter escaped the seal．（You would not want that stuff floating around the cabin!） When the deed was done，the astronaut cleaned up with a piece of plastic attached to the inside of the bag，removed the bag，dropped a disinfectant pill in with the waste matter，and put the whole thing，sealed，into a special container．
Donald W．Rethke，an engineer for Hamilton Standard Space Systems，developed a more private way to answer nature's call：the space toilet．It is somewhat like the kind of toilet one would find on commercial airplanes---with unique adaptations for zero gravity，of course．For instance，it has thigh bars that keep the astronaut from floating off the seat．
The astronaut （male or female） defecates （排便） in a bag and urinates （排尿） in a hose．Solid and liquid wastes are kept separated because at least 85% of the urine is recycled and，yes，after careful filtration，used for drinking and other purposes．（Water is always in demand in space．） A vacuum sucks the waste materials into the toilet，where the waste is compacted into hamburger-like patties for easy storage．Although not exactly like an earthbound visit to the toilet，it is at the very least much more private than in the early days of space travel．

28．According to the first paragraph，the lack of the gravity can turn something as simple asDinto a major challenge．
A．eating        B．taking baths       C．sleeping        D．a(chǎn)nswering nature's call
29．How did astronauts use toilet systems in the Apollo days？
   A．None of the waste was separated as it is now．
   B．Solid waste was compressed and stored on board．
   C．The toilet units used water to remove the waste through the system．
   D．The astronauts each used their own private restroom．
30．To ensure the user remains seated，the toilet comes equipped withD
   A．a(chǎn) plastic bag      B．a(chǎn) sticky strip   C．a(chǎn) wide hose       D．a(chǎn) thigh bar
31．What can be inferred from the fact that most of the astronauts'urine is recycled？B
   A．The recycled water tastes better．
   B．Water is limited on the space shuttle．
   C．It is very convenient to get their urine recycled．
   D．Space science includes recycling urine．

17．Snakebites affect between 1.2 million and 5 million people each year around the world．Adults，children and pets around the world experience them．They can result in swelling，bleeding or even death．Any snakebite can be dangerous if infection sets in．Some types of snakevenommake the bite area swollen or painful．Others cause bleeding or damage the heart's nerves．Here are some especially dangerous snakes：
    The largest of all poisonous snakes，king cobras can reach 5.5 meters in length．Each king cobra bite contains enough poison to kill an elephant-or 20 people．But these massive snakes usually avoid people．They live throughout India，southern China and Southeast Asia．
    A bite from Australia's inland taipan，the world's most poisonous snake，releases enough venom to kill 100 men．The good news is that people rarely come in contact with this snake，and a treatment for its venom exists．
    Russell's viper lives throughout Asia，including India，southern China，and on the island of Taiwan．It prefers grassy fields but can be found in forests and cities．It bites more people and causes more deaths than any other poisonous snake．
    Though short，the common Indian krait packs a powerful punch in its bite．Most often，it strikes people at night while they are sleeping．Since the bite causes little pain，victims are often not sure that they have been bitten until they begin to experience stomach cramps．Without treatment，symptoms will worsen quickly and can lead to death．
    The black mamba，a native of Africa，is actually olive or grey in color．Only the inside of its mouth is black．When black mambas feel threatened by a human，they make a loud hissing sound to warn the person away．If the warning is ignored，the snake will attack the person repeatedly．And they can attack quickly，moving over the ground at speeds of up to 20 kilometers per hour．
    If a snake bites you，try to get back so it doesn't bite again．And try to identify it if you can do so safely．Remove any jewelry that could constrict the bitten area．And avoid moving the affected limb （四肢） to slow the venom's spread．Most importantly to get antivenin，a medicine that will stop the venom's effects．Even the most dangerous bites can be cured with quick medical treatment．（403 words）
