Until recently, the "science of the future" was supposed to be electronics and artificial intelligence. Today it seems more and more likely that the next great breakthroughs in technology will be brought through a combination of those two sciences with organic chemistry and genetic engineering. This combination is the science of biotechnology.
Organic chemistry enables us to produce marvelous synthetic materials. However, it is still difficult to manufacture anything that has the capacity of wool to conserve (保存) heat and also to absorb moisture. Nothing that we have been able to produce so far comes anywhere near the combination of strength, lightness and flexibility that we find in the bodies of ordinary insects.
Nevertheless, scientists in the laboratory have already succeeded in "growing" a material that has many of the characteristics of human skin. The next step may well be "biotech hearts and eyes" which can replace diseased organs in human beings. These will not be rejected by the body, as is the case with organs from humans.
The application of biotechnology to energy production seems even more promising. In 1996 the famous science fiction writer, Arthur C. Clarke, many of whose previous predictions have come true, said that we may soon be able to develop remarkably cheap and renewable sources of energy. Some of these power sources will be biological. Clarke and others have warned us repeatedly that sooner or later we will have to give up our dependence on non-renewable power sources. Coal, oil and gas are indeed convenient. However, using them also means creating dangerously high levels of pollution. It will be impossible to meet the growing demand for energy without increasing that pollution to catastrophic (灾难性的) levels unless we develop power sources that are both cheaper and cleaner.
It is attempting to think that biotechnology or some other "science of the future" can solve our problems. Before we surrender to that temptation we should remember nuclear power. Only a few generations ago it seemed to promise limitless, cheap and safe energy. Today those promises lie buried in a concrete grave in a place called Chernobyl, in the Ukraine. Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerous way.According to the passage, the science of the future is likely to be ________.

Standardized exam in American public education are being reformed. Over the next four years, hundreds of university professors and testing experts will work together to design new assessment system.
The new tests will be computer-based and will measure higher-order skills ignored by the multiple-choice exams used in all states，including students’ ability to read complex texts, synthesize(合成)information and do research projects．
Because the new tests will be computerized and will be administered several times throughout the school year, they can provide faster feedback(反馈)to teachers．If these plans work out, It’ll turn the current testing system upside down．
One group，led by Florida，will be made up of 25 states and the District of Columbia．The group was awarded $170 million．The other group, whose membership over-laps the first，has31 states and is led by Washington．The group was given $160 million．Twelve of the 44 states are
participating in both groups but are expected eventually to choose one set of tests．
The two groups are supposed to work in a friendly competition，though their plans are very similar．Both groups will produce tests that rely heavily on technology and both groups’ tests will include so-called performance-based tasks，designed to mirror complex，real-world situations．
In performance-based tasks，students are given a problem－they could be told, for example, to suppose they are a mayor who needs to reduce a city’s pollution—and must write about how they would solve the problem．
The new tests could be useful to teachers by giving them information on what their students are le
arning, but it might also require some mid-course adjustments.
Over the past decade, the federal No Child Left Behind law has emphasized helping low-achieving students improve their basic reading and math by encouraging states to produce tests that measure relatively low-1evel skills. Although the Bush-era law is still on the books, two
years of Obama administration policy have been leading schools in new directions．.. What is the main idea of this passage?
| A．Obama’s education policy takes the lead. |
| B．A computer-based testing system is adopted. |
| C．American education system has been changed. |
| D．Experts are reinventing the student testing system. |
.Why are multiple-choice exams to be given up?
| A．Because they are not computer-based. |
| B．Because they can’t test students’ higher-order skills. |
| C．Because they can’t provide proper feedback for teachers. |
| D．Because they can’t test students’ general reading ability. |
.The underlined part in Para. 4 probably means________.
| A．the two groups have some shared members |
| B．the other group is more demanding than the first |
| C．the groups have different tasks of their own |
| D．the other group does better than the first group in the task |
.According to the passage, performance-based tasks may refer to tasks that______.
| A．are related to real-world problems |
| B．have to be performed in an imaginary world |
| C．teach us theories through complex problems |
| D．can only be completed by relying heavily on technology |
.. From the last paragraph, we can infer that_________.
| A．the No child Left Behind policy is not helpful |
| B．the Obama administration’s policy is highly praised |
| C．the two policies both emphasize math and reading abilities |
| D．the two policies both emphasize the development of practical skills |
A town in Oxfordshire has become the first in the UK to have biomethane(生物甲烷)gas from human waste piped to their homes for gas central heating and cooking．
Up to 200 families in Didcot now receive the gas via the national gas power system. Head of energy and technology at British Gas，Martin Orrill，said customers wouldn’t notice any difference as the gas is purified to the highest standard and has no smell．The gas is produced at a sewage(污物) treatment works in Didcot．
The entire process takes only less than three weeks, with the sewage being collected and sent first to settlement tanks．The solid waste material is then fed into digesters, where anaerobic bacteria(厌氧菌)digest the sewage，with the aid of enzymes(酶)to speed up the process．The digestion process produces methane，which can be burned to drive machines(甲烷)to prod
uce electricity，or can be purified and fed into the gas network and piped to homes and businesses. British Gas says supplying the gas rather than electricity is far more efficient since around two-thirds of the energy is lost in producing electricity.
Partners in the Didcot project，British Gas，Scotia Gas Network，and Thames Water，all hope to expand the process to other towns，and other companies such as Ecotricity and United Utilities have also announced biomethane projects being planned．One of these projects in Manchester could be supplying 500 homes with biometh
ane by mid next year. Another British Gas project in Suffolk will provide gas from digestion of brewery(啤酒厂)waste to around 235 families．
The Didcot project cost￡25 million and was influenced by promises of government aids aimed at encouraging companies to develop renewable technologies．An EU directive means the UK must ensure at least 15 percent of its energy is from renewable sources by 2020．
The UK produces about 1.73 million tons of sewage annually．If all sewage treatment works in the UK were fitted with the technology，they could supply gas for up to 350, 000 families..Which of the following is TRUE of the biomethane gas?
| A．it’s mainly made from rotting plants | B．It’s an environmentally friendly gas |
| C．Its production process is too long | D．It’s easily recognized by customers |
.What is the function of the enzymes?
| A．To digest the solid waste material | B．To help get rid of anaerobic bacteria |
| C．To help purify the biomethane． | D．To speed up the digestion process． |
.According to the passage，the biomethane gas had better be used.
| A．as the power for vehicles | B．for heating and cooking |
| C．to produce electricity | D．to drive a variety of machines |
.The last three paragraphs mainly show that .
| A．the UK government supports the biomethane projects |
| B．the biomethane projects are very costly |
| C．the biomethane projects still face many barriers |
D．the biomethane project s are promising |
.. What should the text belong to?
| A．Computer science | B．Engineering | C．Energy | D．Business |
The UK has a well-respected higher education system and some of the top universities and research institutions in the world．But to those who are new to it all, sometimes it can be confusing．
October is usually the busiest month in the college calendar．Universities have something called Freshers’ Week for their newcomers．It’s a great opportunity to make new friends，join lots of clubs and settle into university life．
However，having just left the comfort of home and all your friends behind，you can feel nervous when meeting lots of strangers in big halls. Where do you start? Who should you make friends with? Which clubs should you join?
Luckily, there will be thousands of others in the same boat as you worrying about starting their university social life on the right foot．So just take it all in slowly．Don’t rush into anything that you’ll regret for the next three years.
Here are some to
p tips from past students on how to survive Freshers’ week:
·Learn rules．Make sure you know British social etiquette (礼节)．Have a few wine glasses and snacks handy for
your housemates and friends.
·Be kind．Sometimes cups of tea or even pieces of French fries can give you a good start in making friends.
·Be sociable．The more active you are, the more 1ikely you’ll meet new people than if you’re someone who is shy and never leaves his room.
·Bring a doorstop. Keep your door open when you’re in and that sends positive messages to your neighbors that you’re friendly.

Trekking through the mists of the Huangshan mountains , I came upon a young man painting the scenery with traditional brush and ink on rice paper. He smiled proudly as he showed me his work. It was indeed quite beautiful for a painting , but it paled compared to the living scene before my eyes: mountaintops surrounded by light clouds, an endless dance of wind and fog that changes alternately in the dark hills beneath. How futile it must feel for a mere human being to try to capture that , I thought.
Yet for centuries ,these mountains in the heart of China have been a destination for artists and poets , who come to commune with nature in one of its more striking pose-and struggle to replicate its beauty. Along with the artists and poets come lovers ,who grasp locks symbolic of their undying love to the chain fences that protect hikers from the steep cliffs .Seventy miles of trials wind around 72peaks , the two majestic of which are Capital of Heaven and Lotus Flower.
In 1990 ,UNESCO declared Huangshan a Cultural and Natural Property , thereby ensuring that the area’s physical beauty will be preserved forever. Pheasant and deer abound. Hundreds of plants are said to heal the body and the famous hot springs are known for their healing qualities . An hour’s meditation in one of these pools is a great way to end a day of hiking .
The three staging areas for Huangshan visitors are Jade Screen, the Hot Spring area and the North Sea. The Xi Hai and Bei Hai ,located on different summits are three-star hotels serving Chinese and Western food as well as wine and liquor from East and West.
Huangshan may not be exactly off the beaten path , but it is on a road well worth taking. The writer thought the young man ‘s painting .
A not a bit beautiful B not as beautiful as the living scene
C more beautiful than the living scene D beautiful enough to caught the nature’s beauty Why would lovers like to grasp locks to the chain fences?
A because locks symbolize lovers’ forever love
B because locks can protect lovers from the cliffs
C because locks help lovers climb to the top quickly
D because locks contribute to enjoy nature easily What is the purpose of the passage?
A To introduce some hotels in Huangshan mountains
B To recommend Huangshan mountains to tourists
C To speak highly of the beauty of Huangshan mountains
D To stress the convenience to climb Huangshan mountains
