16.Electric cars are dirty.In fact,not only are they dirty,but they might even be much dirtier than their gasoline-powered cousins.
People in California love to talk about"zero-emissions(零排放)vehicles",but people in California seem to be clueless about where electricity comes from.Power plants mostly use fire to make it.Aside from the new folks who have their roofs covered with solar cells,we get our electricity from generators(发电机).Generators are fueled by something-usually coal,oil,but also by heat generated in nuclear power plants.There are a few wind farms and geothermal plants as well,but by far we get electricity mainly by burning something.
In other words,those"zero-emissions"cars are likely coal-burning cars.Because the coal is burned somewhere else,it looks clean.It is not true.It's as if the California Greens are covering their eyes-"If I can't see it,it's not happening."Gasoline is an incredibly efficient way to power a vehicle; a gallon of gas has a lot of energy in it.But when you take that gas (or another fuel) and first use it to make electricity,you waste a nice part of that energy,mostly in the form of wasted heat-at the generator,through the transmission lines,etc.
A gallon of gas may propel your car 25 miles.But the electricity you get from that gallon of gas won't get you nearly as far-so electric cars burn more fuel than gas-powered ones.If our electricity came mostly from wind,or geotherm,or solar,then an electric car truly would be clean.But for political,technical,and economic reasons,we don't use much of those energy sources.
In addition,electric cars'batteries which are poisonous for a long time will eventually end up in a landfill.And finally,when cars are the polluters,the pollution is spread across all the roads.When it's a power plant,though,all the junk is in one place.Nature is very good at cleaning up when things are not too concentrated,but it takes much longer when all the garbage is in one spot.

33.What does the underlined word"clueless"mean in Paragraph 2?D
A.People are seeing the California Greens everywhere.
B.People in California love to talk about zero-emissions vehicles.
C.People in California love to have their roofs covered with solar cells.
D.People there have no idea that so far electricity mainly comes from burning coal,oil,etc.
34.What is the main idea of the passage?A
A.Electric cars are not clean at all.
B.Electric cars are better than gasoline-powered ones.
C.People cast doubts on electric cars'batteries.
D.Gasoline is an efficient way to power a vehicle.
35.The electricity we get from a gallon of gas may make our car runD.
A.not less than 25 miles
B.more than 25 miles
C.no more than 25 miles
D.not more than 25 miles.

Scientists claim to have developed a revolutionary new giant 3D concrete printer that can build a 2,500-square-foot house in just 24 hours.

The 3D printer, developed by Professor Behrokh Khoshnevis from the University of Southern California, could be used to build a whole house, layer by layer, in a single day.

"It is basically scaling up 3D printing to the scale of building," said Khoshnevis.

The giant robot replaces construction workers with a nozzle (喷嘴), which can quickly build a home based on a computer pattern, MSN News reported.

Contour Crafting, as it is named, is a layered fabrication (构造) technology. Using this process, a single house or a colony of houses, each with possibly a different design, may be constructed in a single run, embedded (嵌入) in each house all the wires and pipes for electrical, plumbing and air-conditioning.

The potential applications of this technology are far-reaching including in emergency, low-income, and commercial housing.

"Our research also addresses the application of Contour Crafting in building habitats on other planets. Contour Crafting will most probably be one of the very few feasible approaches for building structures on other planets, such as the Moon and Mars, which are being targeted for human habitation before the end of the new century," researchers said on the project website.

The technology may potentially reduce energy use and emissions. And the main advantages of the Contour Crafting process over existing technologies are the superior surface finish that is realized and the greatly increased speed of construction.

15.Should we allow modern buildings to be built next to older buildings in a historic area of a city?In order to answer this question,we must first examine whether people really want to preserve the historic feel of an area.Not all historical buildings are attractive.However,there may be other reasons-for example,economic reasons-why they should be preserved.So,let us assume that historical buildings are both attractive and important to the majority of people.What should we do then if a new building is needed?
In my view,new architectural styles can exist perfectly well alongside an older style.Indeed,there are many examples in my own hometown of Tours where modern designs have been placed very successfully next to old buildings.As long as the building in question is pleasing and does not dominate (影响) its surroundings too much,it often improves the attractiveness of the area.
It is true that there are examples of new buildings which have spoilt (破坏) the area they are in,but the same can be said of some old buildings too.Yet people still speak against new buildings in historic areas.I think this is simply because people are naturally conservative (保守的) and do not like change.
Although we have to respect people's feelings as fellow users of the buildings,I believe that it is the duty of the architect and planner tomove things forward.If we always reproduced what was there before,we would all still be living in caves.Thus,I would argue against copying previous architectural styles and choose something fresh and different,even though that might be the more risky choice.

28.What does the author say about historical buildings in the first paragraph?D
A.Most of them are too expensive to preserve.
B.They are more pleasing than modern buildings.
C.They have nothing to do with the historic feel of an area.
D.Some of them are not attractive.
29.Which of the following is TRUE according to the author?A
A.Some old buildings have spoilt the area they are in.
B.We should reproduce the same old buildings.
C.Buildings should not dominate their surroundings.
D.No one understands why people speak against new buildings.
30.By"move things forward"in the last paragraph,the author probably means"C".
A.destroy old buildings
B.put things in a different place
C.choose new architectural style
D.respect people's feelings for historical buildings
31.What is the main purpose of the passage?B
A.To explain why people dislike change.
B.To argue that modern buildings can be built in historic areas.
C.To warn that we could end up living in caves.
D.To admit how new buildings have ruined their surroundings.
2.I used to believe courtesy was a thing of the past.Very seldom have I encountered a courteous human being in this modern era.
Recently,I had to change my thinking,when I came face to face with just such a human being in a coffee place,with my two daughters.The place was crowded as usual and we had to climb steep(陡峭)stairs in order to find an empty table.After enjoying coffee and snacks,we went down the narrow stairs,where there was hardly any space for another person to either climb up or come down.
Just as I was in the middle of the stairs,a gentleman entered the main entrance of the restaurant which was right in front of the staircase(楼梯).I was sure I would be pushed roughly by this man going up.I kept coming down as fast as I could.My daughters were already down,looking up at me worriedly,hoping I would reach them before the stranger started walking up the stairs,knowing I was a nervous sort.
Nearly reaching them,I noticed the man still standing near the door.I reached my daughters and passed the stranger at the entrance door which he kept holding open.I looked back thinking he was still at the door,deciding whether to go in or find another less crowded place.I saw him going up the stairs,two at a time.I told my daughters about it and all three of us felt bad that we did not even thank the courteous gentleman who was actually holding the door open for us ladies to pass through before going up.
Such well mannered people are hard to find these days,when pushing is very common in our advanced but aggressive society.We applauded for his chivalry(骑士精神).

D.He would hold the door open for all.
19.You may have heard of the book Moby Dick(《白鲸记》),written by the American author Herman Melville.You may also know that Moby Dick is considered one of the greatest novels ever written.However,it might surprise you to find out Herman Melville was not always a highly regarded author.
Melville's first two novels,Typee and Omoo,were widely read and financially successfully.They were both exciting tales of adventures at sea and experiences with people in foreign lands.Melville became quite famous.However,upon the publication of his third book,Mardi,Melville's popularity began to weaken.He was no longer interested in telling tales of pure adventure,and his writing took on a style that alienated(使疏远) the general reading public of his time.
Melville published Moby Dick in October of 1851.it was an original novel,combining aspects of sociology and philosophy,which confused readers by its complex symbolism.The book sold poorly.
Melville's next book,Pierre,was almost completely disregarded by the public.Debt frustration and ill health finally forced Melville to take a low-paying job as a customs inspector.Eventually,Melville abandoned prose(散文) and began to write poetry.
The Civil War is the main subject of Melville's poetry.He and his brother made a trip to the front line,and he published a book of poems,Battle-Pieces and Aspects of War,based on this experience.
Melville died in 1891at the age of 72.at this point,his work had been completely forgotten by the public.His talent was to go unrecognized for the next thirty years.Then,in 1920s,his reputation began to improve as critics and readers rediscovered his work.Today Moby Dick is one of the best-known novels ever penned by an American author.

24.What were Melville's first two novels mainly about?D
A.His travel experience.B.His successful communication skills.
C.Adventurous experiences in the front line.
D.Adventurous voyages and foreign experiences.
25.We can learn from the text that Moby DickA.
A.sold a little better than Pierre.B.was Melville's favorite novel.
C.was copied from other books.D.made Melville popular again.
26.The text may be taken fromB.
A.a writing guide                          B.a literary journal.
C.a science magazine.D.a critical book on literature.
27.What is the text mainly about?C
A.The main works of Melville.B.The skills in Melville's writing.
C.The ups and downs of Melville.D.The reason for Melville's failure.
