A 500 kg．three-meter-tall ape(猿)lived alongside humans for more than a million years，according to a new study．
Fortunately for early humans，the huge primate’s(灵长类动物)diet consisted mainly of bamboo．
Scientists have known about Gigantopithecus(巨猿)since some of its teeth were discovered on sale in a Hong Kong pharmacy about 80 years ago．The idea of a giant ape aroused the interest of scientists around the world，but It remained unclear when this beast became extinct．
Now Jack Rink，a geochronologist(地质年代学家)at McMaster University in Canada，has used a high-precision absolute-dating method to determine that this ape－the largest primate ever―roamed Southeast Asia for nearly a million years before the species died out 100，000 years ago．By this time，humans had existed for a million years．
“Gigantopithecus is a primate that co-existed with humans at a time when humans were undergoing a major evolutionary change，”said Rink．
Some of Gigantopithecus fossils(化石)were found in Guangxi．It is the region where some believe the modem human race originated．according to Rink．Scientists have been able to piece together a description of Gigantopithecus using just a handful of teeth and a set of jawbones．
“The size of these specimens―the crown of the molar，for instance，measures about an inch (2．54 cm)across―helped us understand the extraordinary size of the primate，”Rink said．
Scientists can only guess at what killed off a beast this size．Some scientists believe that a diet of bamboo combined with increasing competition from more nimble humans eventually led to its extinction．
While most scientists agree that Gigantopithecus died out long ago，some people―Big-foot(大足怪)and Yeti(喜马拉雅雪人)enthusiasts in particular－believe that this ape is the source of tales of giant，hairy beasts living in the woods．
Even though mainstream scientists dismiss these claims，it isn’t impossible．The coelacanth a type of fish thought to have died out millions of years ago-was discovered swimming off the coast of Africa in 193&
53．We can gain some information about Gigantopithecus EXCEPT ．
A．their diet B．their appearances
C．their habitats D．their language(s)
54．What’s the best title for the passage?
A．The Death of the Largest Primate B．The Huge Ape Appears Again
C．The New Findings of Giant Apes D．A Yeti．500 kg＆3-Meter-Tall
55．What can we learn from the third & the fourth paragraphs of the passage?
A．Great apes lived along with ancient men．
B．Jack Rink is the greatest geochronologist．
C．The largest apes once lived in Southeast Asia for nearly 1 00，000 years．
D．The largest apes had existed as long as human beings．
56．Which of the following description about the huge apes is right?
A．They died from the bad habitats．
B．They died out long time ago．
C．They died of hunger．
D．These giant hairy beasts，living in the frost，are legends．

For computer users, there is no bigger excitement than tossing out your old PC and upgrading to a newer, faster and cleaner machine. With hardware designers like Intel, pushing newer, faster products every year, and new software requiring even more powerful machines, companies and consumers have little choice but to go along.
But this rapid turnover is having a serious effect on the planet. Producing a personal computer consumes large quantities of natural resources. A recent study by the United Nations estimates the energy required to produce a single new computer is equivalent to nearly two barrels of oil. And that doesn't include the 22 kg of chemicals or the 1,500 kg of water used in the manufacturing process.
In fact, pound for pound（均等地）, the process for making a car is about 500% more efficient than that for making a computer. That doesn't matter so much 20 years ago when personal computers were few and far between, but times have changed. These days, computers are found nearly everywhere and sales continue to grow. The number of PCs in use topped one billion in 2002.
Waste in production is only half the problem. Old computers, especially the monitors, are full of dangerous substances, which need to be carefully recycled. The problem is sure to expand over the coming years as users replace their boxy CRT monitors with LCD flat displays.
Europe now requires that 70% of parts from old computers be recycled, but the study’s authors say that’s also part of the problem. The solution, they insist, is for governments and companies to encourage people to use their computers longer, and upgrade rather than replace. But considering that much of the world’s recent economic growth has come from spending on computers and information technology, that advice may sound like wishful thinking.
What do computer users have to do every few years according to the passage?
A. Push newer, faster products.
B. Produce more powerful machines.
C. Consume large quantities of natural resources.
D. Upgrade to a newer, faster computer.
What does the underlined word “that” in paragraph 3 refer to?
A. The pound. B. The process.
C. The car. D. The computer.
We can infer from the last paragraph that ____.
A. governments and companies will surely encourage people to use their computers longer
B. governments and companies will probably encourage people to replace their personal computers
C. the world's economic has been growing without people's spending on computers and information technology
D. all parts from old computers are now recycled in Europe
The purpose of writing this passage is ____
A. to encourage companies to push newer, faster personal computers
B. to encourage people to design more new software
C. to encourage people to save their personal computers
D. to encourage people to spend more money on computers and information technology

Thinking of throwing your old cell phone? Think again．Maybe you should mine it first for gold, silver and other metals．It’s called “urban mining”, searching through the small pieces of metal in electronic products for gold, silver and other expensive metals．It is a growing industry around the world as prices for metal grow higher and higher.
The gold and other precious metals from electronic products are melted down and then sold．The metals can be made into jewelry or circuit （电路）for mobile phones．“It can be precious, so we want to recycle whatever we can,” said Tadahiko Sekigawa, president of Eco-System Recycling Co．Ltd.
A ton of ore（矿石）from a gold mine produces just 5 grams of gold on average, while a ton of mobile phones can give 150 grams or more, according to a study by Yokohama Metal Co-Ltd., another recycling company．The same amount of useless mobile phones also contains around 100 kg of copper and 3 kg of silver, among other metals.
Recycling has become more important because prices of metals have hit record highs．Eco-Systems, opened 20 years ago near Tokyo, usually produces about 200 to 300 kg of gold bars a month, worth about $5.9 million to $8.8 million．That’s about the same as a small gold mine.
1．Which of the following statements is right?
A．The amount of recycling precious metal has grown higher.
B．A ton of mobile phones contains about 100 kg of copper and 3 kg of silver.
C．Japan needn’t recycle old cell phones．
D．Eco-Systems near Tokyo produced 500 kg of gold bars a month．
2．Which of the following things may be made from recycled metals?
A．Jewelry． B．Ore． C．Copper． D．Mine.
3．Recycling becomes so important these days because .
A．there are plenty of recycling factory
B．gold can be made into circuit boards
C．prices of metals have hit record highs
D．the metals can be used again in new cell phones
4．What is “urban mining”?
A．Searching through small pieces of metal in electronic products.
B．Melting down the metals and making them into new shapes．
C．Mining for gold, silver and other metals from used cell phones.
D．Another way of saying eco-system recycling factories.
