20.______ that caused him to serve dinner an hour later than usual.

A. It was we being late             B. It was our being late

C. It was we were too late        　D. It was because we were late

B


解析:

此題容易認(rèn)為強(qiáng)調(diào)的是原因狀語(yǔ)從句 because we were late。但實(shí)際上，此題的答案為B，強(qiáng)調(diào)的是句子主語(yǔ) our being late，此題若還原成非強(qiáng)調(diào)句，即為：Our being late caused him to serve dinner an hour later than usual. 注意，強(qiáng)調(diào)句的一個(gè)顯著特點(diǎn)是，若去掉強(qiáng)調(diào)結(jié)構(gòu) it is [was]… that…，句子仍然成立；換句話說(shuō)，該結(jié)構(gòu)中的 it is [was]… that… that 不能充當(dāng)句子成分，而實(shí)際上句中的動(dòng)詞cause需要有自己的主語(yǔ)。

Among the dead in South Asia’s tsunami① were many tourists at Sri Lanka’s national wildlife park at Yala. But very few of the park’s animals — elephants, buffaloes, monkeys and wild cats — appear to have died. There are theories that animals can sense natural disasters and flee to safety.

First, it’s possible that the animals may have heard the quake before the tsunami hit. The underwater rupture likely produced sound waves known as infrasound② or infrasonic sound. Humans can’t hear infrasound, but many animals including dogs, elephants, tigers and pigeons can.

A second early warning sign the animals might have sensed is ground vibration③. The massive quake would have produced vibrational waves known as Rayleigh waves. These vibrations move through the ground like waves move on the surface of the ocean but faster. They travel at ten times the speed of sound. The Rayleigh waves would have reached SriLanka hours before the water hit. Mammals, birds, insects and spiders can sense Rayleigh waves. So the animals at Yale might have felt the Rayleigh waves and then run to higher ground.

But what about humans? While we can’t hear infrasound, we can feel it, although we don’t necessarily know we’re feeling it. We also experience Rayleigh waves by special sensors in our joints, which exist just for that purpose. Sadly, it seems we don’t pay attention to the information when we get it. Maybe we screen it out because there’s so much going on before our eyes and in our ears. Humans have a lot of things on our minds and usually that works out OK.

Notes:

tsunami  n. 海嘯

infrasound  n. 次聲

vibration  n. 振動(dòng)，顫動(dòng)

Choose the best answers according to the above:

Why did few animals at Yala die when the tsunamis that caused a huge number of human deaths hit?

A. Because the animals were staying at a higher place in the park.

B. Because the animals were able to run much faster than human beings.

C. Because human beings cannot hear the infrasonic sound.

D. Because the animals might have picked up the danger signals and ran away.

Which of the statements about “Ravleigh waves” is true?

A. Rayleigh waves are massive vibrational waves that usually cause quakes or tsunamis.

B. Rayleigh waves move on the ocean surface at a speed ten times that of sound waves.

C. Rayleigh waves can be felt both by animals and human beings.

D. Rayleigh waves, just like infrasonic sound, can only be felt by animals.

When a tsunami hits, it is possible that ＿＿＿＿.

A. we can’t feel the infrasound so we can’t be informed of the danger

B. we can feel Rayleigh waves as well as infrasound so we are able to escape the danger like animals

C. we were so busy with things on our minds that we feel neither infrasound nor Rayleigh waves

      D. we think nothing of the information of its coming even though we can also get it

What does the underlined word “that” in the last sentence refer to?

A. Screening out the information.

B. There being so much going on before our eyes and in our ears.

C. Having a lot of things on our minds.

D. Paying attention to the information.

Prince Charles yesterday promised to reduce the royal impact on the environment through sweeping changes to his personal lifestyle and official schedule. The prince will replace carbon-heavy private jets and helicopters with scheduled flights and train services.
The move came as Prince Charles urged business leaders to publish the environmental pact(條款、協(xié)議) of their activities.
He said, “Few accountants and business decision-makers ask, ‘How much of our critical natural resource is left? How many miles of polar ice cap has our business helped melt this year? By how many inches have we raised sea levels? How many species have we put at risk? How many homes will be flooded, how many people will die of thirst or starvation because of our activities? ’ These are not comfortable questions, but, by God, they need to be asked.”
He added, “At the moment these costs do not appear in anyone’s books… Yet they are real, they are incurred now and in a relatively short time, the damage being caused may be beyond remedy.” He said the world was “running up the biggest global credit card debt in history, but with little or no thought for how the bill will ever be paid”.
Flanked by the prime minister and business and community leaders at St James’ Palace, the prince said his new “accounting for sustainability” project would give consumers the power to choose products that caused less damage to the planet.
Duchy Originals, the prince’s food company, is taking steps to work out how much carbon dioxide and other green-house gas are emitted in growing, processing and distributing its products. The changes to the prince’s travel arrangements announced yesterday are part of a wider review of the carbon footprint associated with activities at all three of his residences. Clarence House in London, Highgrove and Birkhall on the Balmorals estate, as well as the activities of his 21 personal and 105 full-time staff. Measures include a review of electricity use, commuter and other staff travel and are intended to identify further reductions in carbon dioxide emissions. The review will report in June , when Clarence House will announce annual targets to reduce carbon emission.
【小題1】How does Prince Charles feel about business leaders in terms of environmental protection?

A．Dissatisfied.B．Disappointed.
C．Doubtful.D．Impatient.
【小題2】In response to Prince Charles’ calls, Duchy Originals will ______.
A．make as much green food as possible
B．cut down its cost
C．figure out its greenhouse gas emission
D．continue its greenhouse gas emission
【小題3】The underlined phrase in paragraph 4 probably refers to ______.
A．the great amount of waste produced by industry
B．the high cost of industry in their producing process
C．the great amount of debts of the royal family
D．the great damage caused to the environment
【小題4】What would be the best title for the passage?
A．Prince Charles promised Greener Royal Lifestyle
B．Better Late than Never
C．Prince Charles and His Concern for Environment
D．The Royal Family Has a Role to Play in Environment Protection

Donald had his own difficulties in sleeping that night. Not just because of the bright lights of the shelter or people’s constant voices, it was the happening repeatedly nightmare that caused him to stay awake, to fear sleep. Donald was back in his small house. He did his best to ignore the howling winds outside his window. Yet he could not turn out the fearful whimpers (嗚咽) of his little dog, or the uncomfortable sounds of his mother anxious in her room next door, unable to sleep through the storm despite her insistence they would be all right.

He did his best to calm his mother, and she had to comfort him. Soon water was seeping (滲入) into the single floor house. Quickly it rose from ankle level to leg level. At Donald’s insistence, they pushed their way through the water --- now chest high --- toward the front door. When they fought their way into the living room, water rose to their chins.

It was a struggle for the boy and mother to stay afloat. In a total panic, desperate to hold on to something, Troy caught a curtain rod. She was breathing hard, shouting that she couldn’t swim.
