| 第4题：Watch out! Here comes London MayorBoris Johnson riding a bicycle from his new bike hire plan. "What we’ve put in is a new form of public transport. These bikes are going to belong to everybody. " More than 12000 people have signed up for the plan. They each receive a key at a cost of three pounds, with costs at one pound for a 24-hour membership, five pounds for seven days, and 45 pounds for an annual membership. John Payne, a London teacher who cycles a lot, is among the first to use the system. "It’s very comfortable. For people who don’t cycle much I think it’ll be very useful.But for people who cycle regularly, they are possibly a bit slow.But they’re perfect for London streets, very strong. I think they’ll be very widely useD、" And Johnson says it’s of good value. "I think it’s extremely good value. The first half hour is free. If you cycle smart and you cycle around London--most journeys in London take less than half an hour, you can cycle the whole day free. " Some 5 000 bikes are currently available at over 300 docking stations (租车点) in central London. Johnson says the city will gradually expand the system, "Clearly one of our ambitions is to make sure that in 2012 when the world comes to London, they be able to use London hire bikes to go to the Olympic stadiums. \ MayorBoris Johnson is riding a bicycle to ______。 A、go to workB、attend a competition C、promote his bike hire plan D、show his love for cycling |

| 第5题：Rubidium, potassium and carbon are three common elements used to date the history ofEarth. The rates of radioactive decay of these elements are absolutely regular when averaged out over a period of time; nothing is known to change them. To be useful as clocks, the elements have to be fairly common in natural minerals, unstable but decay slowly over millions of years to form recognizable "daughter" products which are preserved minerals. For example, an atom of radioactive rubidium decays to form an atom of strontium (another element) by converting a neutron in its nucleus to a proton and releasing an electron, generating energy in the process. The radiogenic daughter products of the decay—in this case strontium atoms—diffuse away and are lost above a certain very high temperature. So by measuring the exact proportions of rubidium and strontium atoms that are present in a mineral, researchers can work out how long it has been since the mineral cooled below that critical "blocking" temperature. The main problems with this dating method are the difficulty in finding minerals containing rubidium, the accuracy with which the proportions of rubidium and strontium are measured, and the fact that the method gives only the date when the mineral last cooled below the blocking temperature.Because the blocking temperature is very high, the method is used, mainly for recrystallized (igneous or metamorphic) rocks, not for sediments—rubidium-bearing minerals in sediments simply record the age of cooling of the rocks which were eroded to form the sediments, not the age of deposition of the sediments themselves. Potassium decays to form (a gas) which is sometimes lost from its host mineral by escaping through pores.Although potassium-argon dating is therefore rather unreliable, it can sometimes be useful in dating sedimentary rocks because potassium is common in some minerals which form in sediments at low temperatures.Assuming no argon has escaped, the potassium-argon date records the age of the sediments themselves. Carbon dating is mainly used in archaeology. Most carbon atoms (carbon-12) are stable and do not change over time. However, cosmic radiation bombarding the upper atmospheres is constantly interacting with nitrogen in the atmosphere to create an unstable form of carbon, carbon-14. The underlined word "cosmic" in the last paragraph is closest in meaning to ______. A、radioactive B、organicC、terrestrialD、universal |
