5．Though the earthquake destroyed many houses，people didn't lose hope．（改為被動語態(tài)）
Though many houseswere destroyedby the earthquake，people didn't lose hope．

分析 句意：雖然地震毀了大量的房子，但是人們沒有失去希望．
雖然大量的房子被地震毀了，但是人們沒有失去希望．

解答 本題考查被動語態(tài)．題干是一般過去式，改為被動語態(tài)也應(yīng)是一般過去時的被動語態(tài)．be+done構(gòu)成被動語態(tài)，主語是many houses，be動詞用were．故答案為：were destroyed．

點評 本題考查一般過去時的被動語態(tài)，解答本題的關(guān)鍵是掌握其構(gòu)成was/were+done．

11．Many people believe that yellowing and wetness are the greatest enemy of stamps．In fact，stamps are afraid of not only wetness，but also light and dirty things．People protect their stamps in several different ways．
To protect stamps，we should  never touch the stamps with our hands．This avoids moving dirty things onto them．Stamp tweezers （鑷子） should be used in all conditions．
Stamps are printed things．The colour will slowly disappear if the stamps are put in the light for a long time．So we should not put stamps in the light for long．Direct sunlight must be avoided as well．
Wetness is an important  problem for stamps．Some  collectors  will put stamps  in separate plastic （塑料） bags．However，it is possible that some stamps have taken in some water from the air before they are put into the plastic bags．Stamps become yellow easily and rapidly after they take in wet air．To protect the stamps，some people also put the stamps into a special room which has a machine to keep the air cool and dry．However，not many people can afford that．
To keep stamps，stamp collectors usually put them under plastic covers．It is a common and simple way．This helps because the plastic cover keeps the stamps off the wet air．It also stops the fingersfrom touching te stamps．
Some  collectors  prefer  to  store  stamps  inside  a  plastic  box  with  desiccants  （干燥劑）．However，we should take care not to let the stamps．touch the desiccants．On top of that，don't  take your stamps out on a wet day．
71題完成句子；72～73題簡略回答問題；74題找出并寫下全文的主題句；75題將文中畫線句子譯成漢語．
71．One way to protect stamps is that we should never touch themwith our hands．
72．What will disappear ifwe put the stamps in the light for long？The colour/The color/Colour/Color
73．When do stamps become yellow easily and rapidly？After they take in wet air
74．People protect their stamps in several different ways．
75．為了保存郵票，集郵者（們）通常把它們（郵票）放在塑料封面下（邊）．

15．Do you think that living a hungry life is last century's story？Well，it may be this century's headline．
The world has growing worries about a global food shortage．Right now，there are still 870million hungry people in the world，according to a survey of the UN's Food and Agriculture Organization．Children can't escape this，either．Around fifteen million children die of hungry each year．
What's causing food shortages？There are several reasons．
There are now more droughts and floods．This is very harmful to farmers and their ability to grow food．
Besides，with the growing population，feeding everyone becomes more difficult．There are a little more than seven billion people in the world．By 2050，the world population will be more than nine billion．
Another reason is food waste．The average person throws away 50kg of food every year．
How can we help with food shortages？The easiest way is to cut down on food waste．
Next time before throwing away the food on your plate，just think how much work has been done to make it．By buying less，we waste less．This takes the pressure off producing so much food．And it helps to solve the problem of food shortage．
You can also ask your schoolmates to join you．
In 2013，researchers at Kansas State University in the US put up short anti-waste slogans（標語） in dining rooms"Think Before You Waste"．Guess what happened？Students wasted fifteen percent less food after that!
The author of the study said，"You don't need a huge activity to make a difference．"
Reasons of food shortage（56）More droughts and floods
The growing population．
（57）Food waste
Ways of（58）helping with food shortage（59）Cut down on food waste
Ask the other students to join in your anti-waste work．
Your understanding of the last sentence．
（60）Stop wasting from ourselves and from tiny/little things．
