19．The Pacific island nation of Nauru used to be a beautiful place．Now it is an ecological disaster area．Nauru's heartbreaking story could have one good consequence-other countries might learn from its mistakes．
For thousands of years，Polynesian people lived in the remote island of Nauru，far from western civilization．The first European to arrive was John Fearn in 1798．He was the British captain of the Hunter，a whaling ship．He called the island Pleasant Island．
However，because it was very remote，Nauru had little communication with Europeans at first．The whaling ships and other traders began to visit，bringing guns and alcohol．These elements destroyed the social balance of the twelve family groups on the island．A ten-year civil war started，which reduced the population from 1，400to 900．
Nauru's real troubles began in 1899when a British mining company discovered phosphate（磷酸盐）on the island．In fact，it found that the island of Nauru was nearly all phosphate，which was a very important fertilizer for farming．The company began mining the phosphate．
A phosphate mine is not a hole in the ground； it is a strip mine．When a company strip-mines，it Comremoves the top layer of soil．Then it takes away the material it wants．Strip mining totally destroys the land．Gradually，the lovely island of Nauru started to look like the moon．
In 1968，Nauru became one of the richest countries in the world．Every year the government received millions and millions of dollars for its phosphate．
Unfortunately，the leaders invested the money unwisely and lost millions of dollars．In addition，they used millions more dollars for personal expenses．Soon people realized that they had a terrible problem-their phosphate was running out．Ninety percent of their island was destroyed and they had nothing．By 2000，Nauru was financially ruined．Experts say that it would take approximately$433，600，000and more than 20years to repair the island．This will probably never happen．

18．EXPERTS have put forward detailed plans for a tunnel to join Taiwan with the Chinese mainland．
The shortest proposed route would be 126 kilometers-more than twice the length of the English Channel Tunnel．And the longest proposed route would be 207 kilometers．
A recent conference in Xiamen，Fujian Province brought together more than 70 experts．The event was co-sponsored by universities from Taiwan and the Chinese mainland．
Fujian is the province where both proposed routes would begin．There is no direct passenger access between the mainland and Taiwan by road or sea at the moment．Experts say that it is better to start research sooner rather than later，despite the current lack of government funding．There are no technical problems to build a Taiwan tunnel．But it will require an improved political relationship across the Straits．
Tsinghua University Professor Wu said，"A special feature of huge projects is that the period of preparation is longer than the period of construction．"For instance，Wu said，the English Channel Tunnel took 14 years of planning and had been discussed for two centuries．And preparations for the huge Three Gorges Dam on the Yangtze River began in the 1950s．
The Xiamen conference focused on the longest southern route，which would use the Taiwan-controlled islands of Jinmen and Penghu as stepping stones．
The first stage of the new project could be a bridge to cover the five kilometers between Xiamen and Jinmen．This would mean that travelling from Xiamen to Jinmen by car would only take five minutes．
The longest tunnel now being planned anywhere in the world is the 54-kilometre land tunnel to link Lyon in France with Turin in Italy．The tunnel will not be completed until 2015-2020．

14．Brad closed the door slowly as Sue left home to visit her mother．（32）Expecting（Expect） a whole day to relax，he was thinking whether to read the newspaper or watch his favourite TV talk show on his first day off in months．"This will be （33）like a walk in the park，"he'd told his wife．"I'll look after the kids，and you can go visit your mom．"
Things started well，but just after eight o'clock，his three little"good kids"-Mike，Randy，and Alex-came down the stairs in their night clothes and shouted"breakfast，daddy．"When food had not appeared within thirty seconds，Randy began using his spoon on Alex's head （34）as if it were a drum．Alex started to shout loudly in time to the beat．Mike chanted"Where's my toast，where's my toast"in the background．Brad realized his newspaper would have to wait for a few seconds．
Life became worse after breakfast．Mike wore Randy's underwear on his head．Randy locked （35）himself in the bathroom，while Alex shouted again because he was going to wet his pants．Nobody could find clean socks，（36）though/although they were before their very eyes．Someone （37）named（name）"Not Me"had spilled a whole glass of orange juice into the basket of clean clothes．Brad knew the talk show had already started．
By ten o'clock，things were out of control．Alex was wondering why the fish in the jar refused his bread and butter．Mike was trying to show off his talent by decorating the kitchen wall with his colour pencils．Randy，thankfully，appeared （38）to be drawing（draw） a picture quietly in the family room，but closer examination showed that he was eating apple jam straight from the bottle with his hands．Brad realized that the talk show was over and （39）reading（read） would be impossible．
At exactly 11：17，Brad called the daycare centre．"I suddenly have to go into work and my wife's away．（40）May/Can/Could/Shall I bring the boys over in a few minutes？"The answer was obviously"yes"because Brad was smiling．

12．Teaching in front of a camera
Wageningen University is keen on developing forms of education that reach people all over the world．The basics of the course topics are covered in short films and three-minute to seven-minute presentations （33）using （ use ） techniques such as animationand voiceover （画外音）．
The online Master's programmes are quite different from the large-scale MOOCs （在线课程），explains Busstra．In the Master's courses，the short"knowledge clips"（短片） dealing with the essential topics（34）are linked （ link ） to an assignment directly to help the students actively absorbthe knowledge themselves．Teachers can also use them to test （35）whether/if the material has come across well．Busstra says："The teacher has to think up new ways of working---getting students to make a film clip，for instance，（36）where they present a research setup they have thought up themselves，or to respond to someone else's idea，or to work on a document in groups．"The students also get the chance to post a question while they are watching an online film---equivalent of putting your hand up during a lecture．Fellow students and teachers can then answer the question online．"There are a lot of misunderstandings about online education，"says Busstra，"one of them being （37）that there is only one way communication．（38）Butpeople are gradually gaining confidence in it．It will stay typically Wageningen：small-scale and based on interaction and group work．"
The investment （39）in online learning is paying off in the regular education programme too，according to Busstra．Students in Wageningen can pick up the basics at home through the knowledge clips．During lectures，teachers（40）can then provide more in-depth analysis，talk about their own work and supervise students more personally．"Increasingly，on-campus and online education will no longer be two separate worlds，"expects Busstra．

10．The truth（41）thattrees are vital to our life is not a secret．They provide us with food，wood and most （42）importantly（important），oxygen．Now there is one more thing we can add to this list-blocking out harmful bacteria from water．
The discovery（43）was made（make） by a team （44）consisting（consist） of scientists from the Massachusetts Institute of Technology （MIT） and high school students（45）who were seeking a natural water filter-one that would help communities in developing countries that do not have （46）acess（accessible） to modern water filter systems．
The（47）researchers（research），led by Professor Rohit Karnik，decided to turn to trees for help because they could allow liquid to flow through，while blocking out air bubbles．
They began by cutting 1.5-inch-wide sections of tree bark from the branches of a white pine tree．The people related then tested the wood's filtering ability by pouring water containing red dye particles of different sizes through．（48）Totheir amazement，they found that it was effective in trapping all the articles．（49）Encouraged（encourage），the team conducted（50）anotherexperiment，this time with water that contained bacteria．Sure enough，the sapwood held back 99% of the bacteria，allowing only 1% to flow through．
