10．They may be tiny，and live for just three months，but ants could be the key to solving climate change．
Rough harvester ants have been found to"weather"minerals in sand to produce calcium carbonate，also known as limestone （石灰岩）．When the ants make this limestone，the process traps carbon dioxide in the rock，ultimately removing it from the atmosphere．
It is uncertain how the minerals are changed，however，and theories vary a lot from ants licking the sand to excreting （排泄） the substance．
Professor Dorn buried sand at six sites in the Catalina Mountains in Arizona，and Polo Duro Canyon in Texas，25 years ago．Every five years，he measured the minerals in the sand，and discovered the ants broke down minerals up to 300 times faster than sand left undisturbed．
Professor Dorn believes the ants collect calcium and magnesium （镁） and use these elements to make the limestone．This may occur when ants lick sand grains to stick them to the walls of their nests．Alternatively，the limestone could be created from bacteria in the insects gut before it is excreted．This process is similar to what's known as carbon sequestration （隔离）．
Natural carbon sequestration is the process on Earth that manages the carbon dioxide expelledby animals and humans．Trees and the oceans help trap this carbon dioxide．
Another method is geological sequestration where the carbon dioxide is pumped into underground chamber，or into areas full of calcium and magnesium．Carbon dioxide reacts with these elements to form limestone．It is this latter method that Dorn believes the ants perform naturally．
But Professor Dorn claims it is still unknown how much atmospheric carbon is removed by the ants．

32．The fifth paragraph is mainly aboutB．
A．how ants break down limestone
B．how ants change minerals into limestone
C．how ants decorate their nests with sand
D．how ants use sand to kill bacteria
33．What is the possible meaning of the underlined word"expelled"？A
A．sent out B．taken in C．broken up D．given away
34．According to Dorn，scientists still don't knowC．
A．the effect of CO₂ on ants'survival
B．the method of ants'removing CO₂
C．the amount of CO₂removed by ants
D．the time when ants absorb CO₂
35．The main idea of the passage is thatD．
A．ants build their nests to keep CO₂ out
B．ants use limestone to absorb a great deal of CO₂
C．ants are pioneers in solving global warming
D．ants may remove CO₂ from atmosphere．

7．Next time you need directions，maybe you can ask an ant．These little creatures are masters of navigation（导航）that some can find their way home whether they're walking forward or backward，according to a study in Current Biology．
Ants often travel long to bring back the food to their nests．But how do they know where they're going？
Researchers went to Spain to mess with some desert ants．They found an active nest and surrounded it with barriers that forced the foraging（搜寻）ants to follow a particular path back home．Once the ants were familiar with the maze，the researchers would take them up，hand them pieces of a cookie and then put them back in a different location，one that required taking a 90 degree turn to get to the nest．
The research found that the ants carrying a small，easy-to-carry piece would run forward with confidence and were able to head on home．Some ants，however，would drop the cookie and turn around to take a look at the scenery，which allowed the six-legged experts to reset their inner maps，catch their cookies and head in the right direction．
These ants seem to use sky clues，like the position of the sun，to keep them on track．When the researchers used a mirror to make it look like the sun on the other side of the sky，the cornered ants would turn tail for the opposite direction．
So ants integrate（整合）a lot of information to successfully bring home the food．

28．What does the word"maze"in Paragraph 3 probably refer to？D
A．A nest that active ants live in．
B．An experiment that is done in the desert．
C．A method that helps to locate food．
D．A place that consists of confusing paths．
29．Why did some ants stop to look at the scenery？C
A．To get over the man-made barriers．
B．To enjoy the scenery along the route．
C．To ensure they're in the right direction．
D．To check directions with their maps．
30．According to the passage，what probably helps the ants find their way home？A
A．The position of the sun．
B．One particular path．
C．A 90 degree turn．
D．Pieces of a cookie．
31．Where does this passage probably come from？C
A．An adventure novel．
B．A geography textbook．
C．A science magazine．
D．A tourist brochure．

9．The first-ever direct China-to-Britain freight train（货运列车）arrived in London last week．It was the （61）latest（late）evidence of China's efforts to redevelop the"Silk Road"trade routes that once stretched from Asia to Europe．
（62）Having travelled （travel）from China through Kazakhstan，Russia，Belarus，Poland，Germany，Belgium and France for 18days，the train finally arrived in London．Inside the 68containers （63）were （be）household goods，clothing，cloth，bags and suitcases．"This is （64）twice （two）as quick as sea and it's much，much cleaner and cheaper than air freight，"said Philippa Edmunds，（65）who works at the British Campaign for Better Transport．
But the train itself may be more important than the goods （66）it was carrying．Observers say the trip had a political message that China is developing new trade routes and new markets．China needs to find more places（67）to sell（sell）the goods it makes．That is the （68）belief（believe）of Jie Yu from the London School of Economics．"The domestic market in China now seems not to be very promising，so the Chinese are （69）desperately （desperate）looking for the new markets．And obviously that freight train serves （70）asa very good vehicle for the Chinese manufacturers and may help restore the business confidence inside China．"
