题目内容

【题目】阅读下列这首诗,回答问题。

送杜十四之江南

荆吴相接水为乡,君去春江正渺茫。

日暮征帆何处泊,天涯一望断人肠。

(1)第二句中的渺茫一词在诗中有哪些含义? 春江正渺茫征帆何处泊形成强烈的对比,突出表达了作者怎样的情感?

2诗的前三句和第四句在抒情方式上有什么不同?两者之间有何联系?

【答案】(1)渺茫一词包含着复杂的情感,从字面上来看它是描写眼前景:春江上烟波浩淼,雨雾蒙蒙,其实是写诗人心中的茫然,写出诗人送别友人时的怅然若失。

春江渺茫征帆一片,形成一个强烈对比,阔大的背景衬托出一片征帆的渺小真有点担心那征帆晚来找不到停泊的处所,表现出诗人对朋友一片殷切的关心。同时,揣度行踪,可见送者的心追逐友人东去,又表现出一片依依惜别之情。2)前三句主要写景,饱含感情,含蓄委婉;末句则卒章显意,断人肠直抒别情。前三句蓄势(为下句抒情作准备),结句点破,将惜别之情上升到顶点。

【解析】(1)第一问先要答出渺茫一词的表面含义,其次要答出深层含义,二者缺一不可。第二问主要是从对比手法运用中答出其中的情感表达。2考查对诗歌技巧的理解。前三句主要是寄情于景,后一句主要是直抒胸臆,结合具体内容表述二者之间的关系。

【题目】Electric cars are dirty. In fact, not only are they dirty, they might even be more dirty than their gasoline-powered cousins.

People in California love to talk about “zero-emissions vehicles,” but people in California seem to be clueless about where electricity comes from. Power plants most all use fire to make it. Aside from the few folks who have their roofs covered with solar cells, we get our electricity from generators. 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. It's just the coal is burned somewhere else so it looks clean. It is not. 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 nukes, or geothermal, or hydro, or solar, or wind, 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 a lot longer when all the garbage is in one spot.

【1】 What does the underlined word“clueless” mean in paragraph 2?

AThe California Greens are covering their eyes.

BPeople in California love to talk about zero-emissions vehicles

CPeople 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.

【2】What is the main idea of the passage?

A. Electric cars are not clean at all.

B. Electric cars are better than gasonline-powered ones.

C. People cast doubts on electric carsbatteries.

D. Gasonline is an efficient way to power a vehicle.

【3】 The electricity we get from a gallon of gas may make our car run __________.

A. not less than 25 miles.

B. more than 25 miles.

C. no less than 25 miles.

D. not more than 25 miles.

【4】According to the passage, electric cars _________.

A. do not burn fuel and more environmental.

B. are toxic and it is difficult for nature to clean it up when their batteries are buried in one spot.

C. are very good at cleaning up when things are not too concentrated

D. are poisonous for a long time and will eventually end up in a landfill

【5】 It can be inferred from the passage that __________.

A.Being green is good and should be encouraged in communications

B.Electric cars are not clean in that we get electricity mainly by burning something.

C.Zero-emissions vehicles should be chosen to protect our environment.

D.Electric cars are now the dominant vehicle compared with gasoline-powered cousins.

【题目】A California family drives a car that could help protect the environment.

When Jon and Sandy go to the store or to their daughters’ soccer games, they drive in high-tech style. They drive a $1 million, fuel-cell-powered car. It may be the worlds most expensive car and one of the most environmentally friendly cars.

The FCX is the first fuel-cell-powered car to be used by a family

anywhere in the world. The FCX uses hydrogen and oxygen for fuel.

Car makers have been working to develop vehicles that are better for the environment. They are developing cars that use fuel other than gasoline.

what is fuel cell technology?

Fuel cell technology works by changing the chemicals hydrogen and oxygen into water. This process produces electricity, and water vapor which comes out of the exhaust pipe. Most cars release dangerous gases such as carbon monoxide(一氧化碳) and carbon dioxide. Many scientists say these gases are major contributors to global warming.

“The FCX is driven just like any other vehicle on the road, but

without the gases which pollute the environment, scientists say.

Fuel cell technology has been around since the 1800s, but scientists have yet been to perfect it. They say it may take years before the technology is ready for widespread use.

Creating environmentally friendly cars

Another earth-friendly car is already on the market.

Hybrid cars use both gasoline and an electric motor. They are becoming more popular with customers because they cut pollution and improve fuel efficiency.

【1】 Which of the following about the FCX is NOT true?

A. It may be the most expensive car in the world.

B. It is one of the most environmentally friendly cars.

C. It releases dangerous gases to pollute the air.

D. It uses hydrogen and oxygen for fuel other than gasoline.

【2】According to the passage, what is the major cause for global warming?

A. Gases from FCX.

B. Water vapor from cars.

C. Hydrogen and oxygen.

D. Gases from cars.

【3】 From the passage, we know that fuel cell technology _______.

A. works by water

B. has a history for over two hundred years

C. works by electricity

D. has been widely used since the 1800s

【4】 We can infer from the passage that _______ .

A. future cars will be environmentally friendly

B. there will be no gasoline for cars

C. people can’t afford to buy cars in the future

D. global warming has been stopped

【5】 Hybrid cars are popular because _______ .

A. they are the fuel-cell-powered cars

B. they are energy-saving and cut pollution

C. they are perfect cars in the world

D. they produce gases to pollute the environment
