But artificial photosynthesis(光合作用) may someday help change that.Battery storage is being developed as a way to feed renewable power onto the power grid(电力网) regardless of the weather or the time of day. But some scientists are looking to plants and trees for another solutionusing a manmade leaf that can turn solar energy into fuel in the form of liquid sugars or carbohydrates(碳水化合物)In nature, plants use energy from the sun and convert it into chemical energy to be used later. Scientists at Caltech think they have discovered a missing link in the Proceedings of the National Academy of Sciences of the United States of America.Nate Lewis, professor of chemistry at Caltech said, “If you want to bring on renewable sources, youve got to find a way to store carbonfree power and got to get highenergydensity transportation fuels carbonneutral. We have to be ready with technology that can do both of those things.”“Artificial photosynthesis is the leading candidate for that job. The idea is that we want to take sunlight, water and potentially CO2 as the inputs and make fuel as the output,” Lewis said.Scientists think that discovery shows artificial photosynthesis can work, but more research needs to be done to perfect the technology, which is likely to mature over the next decade or so.Besides, there are also enormous challenges that arent likely to be overcome soon, including building new infrastructure to store, transport and use solar fuel. Production challenges of making artificial leaves havent been solved, either.When will commercialscale artificial photosynthesis technology start reducing greenhouse gas emissions?“When will the world get serious and charge carbon?” Lewis said. “When you answer that for me, you will also have the answer to your question.”21What is the disadvantage of solar power?AIt cant be stored. BIt isnt renewable.CIt depends on the weather. DIt is limited in amount.22What does the underlined word “convert” in Paragraph 3 probably mean?ATransform. BContribute.CTranslate. DTransport.23According to the passage, artificial photosynthesis _.Awill replace solar energyBcant work in practiceCmakes water and CO2 as the outputDstill needs to be improved24From the last paragraph we can infer that Lewis _.Aisnt sure of the new technologyBthinks there is still a long way to goCthinks people dont take the technology seriouslyDis dissatisfied with the question.完形填空I heard a click as I rushed off my back door to stop Caesar, the dog, running after a _25_ rabbit.When he gave it up, I turned the door handle hoping to let him back in. But the door wouldnt move. The earlier “click” now _26_. Max, another dog inside, had hit the _27_ mechanism when jumping onto the door!I neither kept a _28_ hidden outside nor one for the neighbour for such _29_. My husband wasnt _30_. I was on my own except for the baby I was to _31_Max ran from room to room, peering(仔细看) through the _32_ at me as if playing a game of peekaboo(藏猫猫). I hoped hed jump up and hit the handle again.“Come on,”I called. “A treat?”I raised my hand upward and _33_ the word “treat”,hoping to get his _34_ legs off the ground. _35_,he lay down! I had taught him whenever I _36_ him with a snack! Caesar lay down, too!It was time to call a locksmith. I headed to the gate for my neighbours house, but _37_, the gate was locked.I kicked off my shoes and started to climb the fence. On the top, I turned and _38_ myself down the other side. Unfortunately, I hooked(勾住) my toes and my skirt. _39_ my balance, I fell heavily.I managed to ring the doorbell.“Are you okay?” my neighbour asked.Twenty minutes later, a white van(货车) _40_ into the driveway. The man asked, “And ID?”“Its in my wallet inside,” I said, and for the first time, I began to _41_“Will the neighbour vouch(担保) for you?”he asked. I nodded.Finally, I stood in the house. As I changed my _42_ clothing and placed a bag of ice on my backside to ease the _43_ from my sudden landing, a sharp bark _44_ me: Caesar wanted his treat!25A.running Bfleeing Cscreaming Dsleeping26A.made sense Bmade out Cmade it Dmade up27A.trapping Bescaping Clocking Dopening28A.dog Bcar Clock Dkey29A.fortune Bchases Cdangers Demergencies30A.at home Bat work Con duty Don business31A.carry Bdeliver Ccare Dattend32A.doors Bwalls Ccurtains Dholes33A.pronounced Bspelt Ctranslated Drepeated34A.strong Bfront Cback Dlong35A.Therefore BOtherwise CInstead DBesides36A.rewarded Bblamed Cpunished Drelaxed37A.slowly Bunfortunately Cgenerally Dsimilarly38A.threw Binspired Clowered Dinserted39A.Keeping BLosing CGaining DPaying40A.pulled Bdrove Cdived Drushed41A.shout Bscold Ccry Dexplain42A.ragged Bold Cworn Dplain43A.pleasure Bdifficulty Cpain Dfear44A.warned Bexcited Castonished Dinterrupted.语法填空阅读下面材料,在空白处填入适当的内容(1个单词)或括号内单词的正确形式。A long time ago, there was a huge apple tree.
