In spring, you may have seen white foam(泡沫) on a green tree or other plants. As a matter of fact, the foam is where young spittlebugs(吹沫虫) live. These insects are protected by the foam, and they usually don’t do much harm to the plants.

As we all know, in late summer, a mother spittlebug lays her eggs on the plant. The babies will hatch(孵化) in spring. After they come to the new world, they begin to eat juice from the plant. The babies eat more juice than their bodies need for food. The extra juice mixes with a special waste that the spittlebugs produce. When this fluid(液体) is released, it mixes with the air, forming bubbly foam.

What is so great about having a foam home? The space inside is so wet that it can keep the bugs’ soft bodies from drying out. And the foam tastes bad, so it keeps away most animals that would eat the bugs. Some birds will reach their heads through the foam to find the bugs. Wasps and ants might eat them, too. But most of the bugs stay safe inside the foam.

Once the bugs have grown into adults, they stop making foam. They leave their homes and jump from plant to plant in search of food. The adults look a little like tiny frogs. For this reason they are also called froghoppers.

If you see some foam on a plant, you might want to take a careful look inside. Gently push some of the foam aside with a small stick. Deep inside you may see a few insects eating plant juice. They might also be making more foam. Be sure to push the foam back after a moment to cover the insects and keep them safe. Soon the spittlebugs will grow up and leave their foam home. They will join the other insects in the grassland.

1.The eggs of spittlebugs_____.

A. are laid in late spring

B. have to pull through a winter before they hatch

C. are protected by mother spittlebugs all the time

D. will be eaten by ants

2.According to the passage, the white foam_____.

A. does much harm to the plant

B. protects the plant from being harmed

C. is where a mother spittlebug is living

D. is plant juice mixed with spittlebugs’ waste and the air

3.Which of the following is a function of a foam home?

A. Protecting the bugs from being eaten.

B. Helping the bugs find food.

C. Providing enough drinking water for the bugs.

D. Keeping the plant from drying out.

4.After the spittlebugs grow into adults, they______.

A. continue to make foam

B. take on a different look

C. begin to eat tiny frogs

D. begin to do harm to plants

A fierce earthquake struck Haiti on January 12, 2010, causing a crowded hospital to fall down and countless houses and buildings were destroyed.

The earthquake, the worst in the region in more than 200 years, with a magnitude estimated at 7.0, struck just before 5 p.m. about 10 miles southwest of Port-au-Prince, leaving the region nearly in ruins. As night fell in Port-au-Prince, Haiti’s capital, fires burned near the shoreline downtown, but otherwise the city fell into darkness. The electricity was out, telephones were not working and relief workers struggled to make their way through blocked streets.

In this earthquake, it was not possible for officials to determine how many people had been killed and injured. It was reported that the headquarters of the United Nations mission was seriously damaged and many employees were missing. Part of the national palace had fallen to the ground. A hospital was totally ruined in Pétionville, which is home to many diplomats(外交官) and wealthy Haitians. A New York reporter said that a wall at the front of the Hotel Oloffson had fallen, killing a passer-by. A number of nearby buildings was badly damaged, trapping people. People were screaming, calling for help from every corner.

Haiti sits on a large fault between the much larger North American plate to the north and the Caribbean plate to the south. The earthquake on Tuesday happened when what appears to be part of the southern fault zone broke. With many poor people living in tin-roof shacks(窝棚) and with many of the buildings in Port-au-Prince and elsewhere in the country of questionable quality, it was expected that the quake caused major damage to buildings and great loss of life.

1.What was the damage of the earthquake?

A. The headquarters of the UN mission was totally destroyed.

B. Some of the national palace had fallen to the ground.

C. A hospital was partly ruined in Pétionville.

D. All the walls of the Hotel Oloffson had fallen.

2.Which of the following statements is TRUE according to the text?

A. All the hospitals in Haiti were destroyed in the earthquake.

B. The earthquake was the worst in Haiti in less than two centuries.

C. After dark the city fell into darkness because of the earthquake.

D. Communication, electricity and transportation were all affected.

3.It can be learned from the text that ________.

A. fires broke out in the capital city due to the earthquake

B. Haiti covers the entire geographic plates of the earth

C. the earthquake caused the southern fault zone to break

D. a grand hotel was completely ruined in Pétionville

4.In Haiti, one way to reduce losses in earthquakes is probably to ________.

A. repair the Southern fault zone

B. move to the seaside

C. improve the quality of the buildings

D. live in tin-roof buildings

The behaviour of a building’s users may be at least as important as its design when it comes to energy use, according to new research from the UK Energy Research Centre (UKERC). The UK promises to reduce its carbon emissions (排放)by 80 percent by 2050, part of which will be achieved by all new homes being zero-carbon by 2016. But this report shows that sustainable building design on its own — though extremely important — is not enough to achieve such reductions: the behaviour of the people using the building has to change too.

The study suggests that the ways that people use and live in their homes have been largely ignored by existing efforts to improve energy efficiency,which instead focus on architectural and technological developments.

‘Technology is going to assist but it is not going to do everything,’ explains Katy Janda, a UKERC senior researcher, ‘consumption patterns of building users can defeat the most careful design.’ In other words, old habits die hard, even in the best-designed eco-home.

Another part of the problem is information. Households and bill-payers don’t have the knowledge they need to change their energy-use habits. Without specific information, it’s hard to estimate the costs and benefits of making different choices. Feedback (反馈) facilities, like smart meters and energy monitors,could help bridge this information gap by helping people see how changing their behaviour directly affects their energy use; some studies have shown that households can achieve up to 15 percent energy savings using smart meters.

Social science research has added a further dimension (方面),suggesting that individuals’ behaviour in the home can be personal and cannot be predicted —whether people throw open their windows rather than turn down the thermostat (恒温器) , for example.

Janda argues that education is the key. She calls for a focused programme to teach people about buildings and their own behaviour in them.

1.As to energy use, the new research from UKERC stresses the importance of________.

A. zero-carbon homes

B. the behaviour of building users

C. sustainable building design

D. the reduction of carbon emissions

2.The underlined word “which” in Paragraph 2 refers to “________.”

A. the ways B. their homes

C. developments D. existing efforts

3.What are Katy Janda’s words mainly about?

A. The importance of changing building users’ habits.

B. The necessity of making a careful building design.

C. The variety of consumption patterns of building users.

D. The role of technology in improving energy efficiency.

4.The information gap in energy use _______.

A. can be bridged by feedback facilities

B. affects the study on energy monitors

C. brings about problems for smart meters

D. will be caused by building users’ old habits

5.What does the dimension added by social science research suggest?

A. The social science research is to be furthered.

B. The education programme is under discussion.

C. The behaviour of building users is unpredictable.

D. The behaviour preference of building users is similar.

Argentina in the late nineteenth century was an exciting place. Around 1870, it was experiencing an economic boom, and the capital, Buenos Aires, attracted many people. Farmers, as well as a flood of foreigners from Spain and Italy, came to Buenos Aires seeking jobs. These jobs didn’t pay well, and the people felt lonely and disappointed with their new life in the city. As the unhappy newcomers mixed together in the poor parts of the city, the dance known as the tango (探戈舞) came into being

At the beginning the tango was a dance of the lower classes. It was danced in the bars and streets. At that time there were many fewer women than men, so if a man didn’t want to be left out, his only choice was to dance with another man so that he could attract the attention of the few available women. Gradually, the dance spread into the upper classes of Argentinean society and became more respectable.

In Europe at this time, strong interest in dance from around the world was beginning. The interest in international dance was especially evident in Paris. Every kind of dance from ballet to belly dancing could be found on the stages of the Paris theaters. After tango dances from Argentina arrive in Europe, they began to draw the interest of the public as they performed their exiting dance in cafes. Though not everyone approved of the new dance, saying it was a little too shocking, the dance did find enough supporters to make it popular.

The popularity of the tango continued to grow in many other parts of the world. Soldiers who returned to the United States from World War I brought the tango to North America. It reached Japan in 1926, and in 2003 the Argentinean embassy in Seoul hired a local tango dancer to act as a kind of dance ambassador, and promote tango dancing throughout South Korea.

1.The origin of the tango is associated with _________.

A Belly dances B. American soldiers

C. the capital of Argentina D. Spanish city

2.Which of the following is true about the tango?

A. It was created by foreigners from Spain and Italy.

B. People of the upper classes loved the tango most

C. A dancer in Seoul became the Argentinean ambassador.

D. It was often danced by two male in the beginning

3. Before World War I, the tango spread to __________.

A. America B. Japan

C. France D. South Korea

4.What can be the best title for the text?

A. How to Dance the Tango

B. The History of the Tango

C. How to Promote the Tango

D. The Modern Tango Boom
