Article: When a handheld video game runs out of power,all you have to do is plug it in and charge it up.Within a few years,some of you might do the same thing with mom's car.Automobile companies are developing vehicles that will plugin to electric sockets ,just like many laptops,digital cameras,cellphones and small video game players do.Called "plugin hybrids ",these cars will get most of their power from electricity.Their drivers will rarely have to stop at gas stations. The technology is more than just cool.In our automobilefilled world,plugin vehicles could reduce the amount of gasoline we use.That gas is made from crude oil ,which keeps rising in cost.Plus,driving around in these hybrids may even help the environment.Gasburning cars produce a lot of carbon dioxide,a type of greenhouse gas.These gases stay in the atmosphere,where they trap heat and cause global warming. The first companyproduced plugin hybrids could hit the roads by 2010.But engineers still have a lot of work to do to make the technology practical and inexpensive. Batteries are the biggest challenge.In the pluginhybrid world,lithiumion (Liion) batteries are getting the most attention.These batteries can store a large amount of energy in a small package,and they last a ly long time between charges.Liion batteries are standard in laptops,cellphones,heart devices and other similar portable devices. But because cars are so big and heavy,it would still require a suitcasesized Liion battery to power about 12km of driving.What's more,the batteries are extremely expensive. "A car filled with batteries could go a long distance," says Ted Bohn,an electrical engineer in Chicago."But it couldn't haul any people,and it would cost $100,000." So researchers need to figure out how to make batteries smaller and cheaper,among other questions. "The answers don't exist yet," Bohn says."As a kid I thought someone someplace knows the answer to everything.All of these questions haven't been decided.That's what engineering is about--making a guess,running... Question: Which is TRUE according to the passage? - The plugin hybrids will use electricity completely as driving power. - The new technology will contribute to the protection of our environment. - The technology of using electricity as driving is quite mature now. - The biggest challenge of the new technology is that it will cost us more money.
The new technology will contribute to the protection of our environment.

Read the following article and select the best answer. Article: Buckingham Palace has a history that dates back over 500 years and has changed hands on numerous occasions, however, much of the building that remains standing today is from the original structure built in the early 1700's. In the beginning Buckingham Palace was originally known as Buckingham House. However, in 1762 George III liked the house so much that he bought it for 28,000 and renamed it "The Queen's House". The reason for this was down to the fact that he bought the house to give to his wife Charlotte. Shortly after he did this, work soon began in order to remodel the house with the help of Sir William Chambers. This trend then continued with the accession of George IV in 1820 when he decided to reconstruct the house but he still used it for the same purpose that his father did. One of the biggest physical changes to the house occurred several years later when the king had a change of mind. It was in 1826 that King George IV set about transforming the house into what it is known today, Buckingham Palace. He did this with the help of an architect known as John Nash. The work that Nash carried out involved doubling the size of the main block through adding a new suite of rooms on the garden side facing the west. He then faced this with mellow Bath stone, which reflected the French neo-classical influence favored by George IV. Many of the rooms that Nash added still remain pretty much unchanged today. The palace as it stands today acts as not only the London residence of Her Majesty the Queen but also the administrative headquarters of the Royal Household. It is in fact one of the few working royal palaces that remain in the world today. The state rooms are extensively used by the Queen as well as members of the royal family as a way of receiving and entertaining guests on state, ceremonial and official occasions. Question: George IV reconstructed Buckingham House probably to _ . - please his own wife - satisfy his son - sell at a good price - honor his old father
(Answer)
please his own wife

Ques:Read the following article and select the best answer. Article: Dear Students, I am delighted to be your guest. I would like to tell you about myself. I have been a news reporter for the past fifteen years. I chose this job so I could travel the world, but the job has taught me many unforgettable lessons. The work is sometimes difficult. I have seen _ , wars, earthquakes, poverty and death. But I have also seen courage, hope and happiness. In India, I visited a city where there were many homeless children. Some were as young as four years old. They lived in the streets and survived by begging or stealing. But then a wonderful lady called Rosa opened a home for them. Within one year, she was looking after two hundred children. She clothed them, fed them, and taught them. She gave them hope. Another time, I was in Turkey after a terrible earthquake, in one place. I found an old lady whose house was in ruins, her son was missing and rescue workers said there was no chance that he was still alive. But the old lady did not give up hope. For four days, she moved heavy stones one at a time by herself. She did not stop until she found her son. He was alive. Here in China, I met a young boy with a serious condition. He had undergone twenty operations and spent nearly his whole life in hospital. I thought he would be sad, but when I met him, his smile was so warm and welcoming. In life, we need role models that we can admire and learn from. When my life is difficult, I try to remember the courage and goodness of these three people. Question: What can we learn about Rosa? - She's a rich lady and she likes to help the homeless children. - She's a great mother and she looks after the homeless children. - She's a kind-hearted woman and she provides houses for the homeless children. - She's a good teacher and she teaches the homeless children.
