The US will seek to expand its own oil production in an attempt to reduce dependence on imported oil and bring down fuel prices , President Obama says . New contracts for exploration will be signed in non-protected areas of Alaska and in the Gulf of Mexico.
In his weekly speech , the President insisted the US could reduce its need for imported oil and improve safety. Using his speech to tell Americans that he understood their concerns about rising prices, President Obama focused particularly on the price of fuel, which has risen in recent months.
US consumers have historically enjoyed cheap fuel , but have seen prices rise in recent months even though US oil production in 2010 reached its highest level for seven years.
Although the oil spill in the Gulf of Mexico in 2010 was serious, Mr Obama said the Gulf remained a key part of the country’s future energy supply.
The President’s proposals (议案）come after Republicans (共和党人） introduced a series of proposals that would expand and speed up oil and gas production.
The White House has criticized the Republican proposals for safety reasons , but Mr Obama was clear in his speech that he felt safety and environmental standards could be maintained even though production might rise.
“ I believe that we should continue to expand oil production in America —even as we increase safety and environmental standards ,”he said.
“As a nation, we should be investing in the clean, renewable sources of energy that are the solution to high gas prices.”
Mr Obama has previously called for a step-change in energy policy, saying the US must move towards getting 80%of its electricity from clean energy sources by 2035.Which of the following is NOT included in Mr Obama’s speech?
| A．The dependence on imported oil. |

| C．The reason for the rising oil prices . |
| D．Expanding oil production. |

| B．US oil production is too small to keep the present low fuel prices. |
| C．The US produced the most oil in 2010 in its history. |
| D．The Gulf is still important in energy supply in spite of the oil spill in 2010. |
Which of the following can serve as the title?

The Antarctic is actually a desert. It’s the only continent on the earth without a river or lake.
The Antarctic is all ice all year round. The warmest temperature ever recorded there is zero, at the South Pole. Explorers used to think that a place so cold would have a heavy snowfall. But less than ten inches of snow falls each year. That is less than half an inch of water. The times that much water falls in parts of the Sahara.
The little snow that falls never melts. It continues to pile up deeper and deeper year after year and century after century. When the snow gets to be about 80 feet deep it is turned to ice by the weight of the snow above it.
1. Antarctic is called a desert because it _______.

IN THE BEDROOM
Don’t smoke in bed ------it causes 1000 fires a year, many with fatal (致命的)results.
Don’t overload your electrical points: the right way is “one appliance（电器）, one socket”（插座）.
Don’t use an electric underblanket over you or an overblanket under you. An underblanket , unless of the low- voltage type, MUST be switched off before you get into bed.
Never let furniture or clothing get close to a lighted fire. Make sure that there is a suitable guard for the room heater.
Keep aerosol-type containers （喷雾器）away from heat and NEVER burn or puncture（刺穿）them.
Don’t dim a table lamp by covering it: buy a low-wattage bulb（灯泡）.
Pajamas （睡衣）and nightdresses, especially for children and elderly people, should be made from flame- resistant material.
IF CUT OFF BY FIRE
Close the door of the room and any fanlight or other opening and block up any cracks （缝隙）with bedding, etc.
Go to the window and try to attract attention.
If the room fills with smoke, lean out of the window unless prevented by smoke and flame coming from a room below or nearby. If you cannot lean out of the window, lie close to the floor where the air is clearer until you hear the fire brigade（队）.
If you have to escape before the fire brigade arrives, make a rope by knotting together sheets or similar materials and tie it to a bed or another heavy piece of furniture.
If you cannot make a rope and the situation becomes intolerable（难耐的），drop cushions or bedding from the window to break your fall, get through the window feet first, lower yourself to the full extent of your arms and drop.
If possible drop from a position above soft earth. If above the first floor, drop only as a last resort.

On October 12, 1989, some Chinese scientists were working at the computers to look for information they needed. Suddenly they saw a lot of very bright spots crossing the computers’ screens. At the same time, the computers were working much slower. To find out what was happening they stopped their work to check some parts of the computers. To their horror, they found out that most of their stored information was got rid of by computer viruses! Obviously all these computers had been infected （传染）by computer viruses.
It is said that the computer viruses were made by a group of young men fond of playing tricks. They all had excellent education. They created the viruses just to show their intelligence. These kinds of computer viruses are named Jerusalem Viruses. These viruses can stay in computers for a long time. When the time comes they will attack the computers by lowering the function, damaging their normal programs or even getting rid of all the information.
We now come to know that Jerusalem Viruses often attack computers on Fridays and that they are spreading to a lot of computers. Among the countries that suffered computer viruses last year are Britain, Australia Switzerland and the US. But till now, how to get rid of the terrible viruses remains a problem.
1.The group of young men created the viruses to _______.

3.the most serious damage caused by the viruses is that _______.

B. the normal programs are damaged
C. all the information stored in the computers is gone
D. the computers infected by the viruses can no longer be used
4.According to the passage, which of the following is true?
A. last year four countries found their computers were infected by viruses

Fire fighting is a serious matter. Knowing what to do during a fire can save people’s lives. It is important to know the ways you can use and show them to everyone else in the family, such as stairways and emergency exits, but not elevators（电梯）.
From the lower floors of buildings, escape through windows is possible. Learn the best way to get out from a window with the least chance of serious injury.
The second floor window is usually not very high from the ground. An average person, hanging by the fingertips will have a drop of about 6 feet to the ground. It is about the height of an average man. Of course, it is safer to jump a short way down than to stay in a burning building.
Windows are also useful when you are waiting for help. Be sure to keep the door closed before opening the window. Otherwise, smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked into the room.
On the second or third floor, the best windows for escape are those which open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement might end in injury. Bushes and trees can help you to have a soft landing.
1. Which of the following should not be used when trying to escape from a fire?
A. windows B. elevators C. fire exits D. stairways
2. How far from the ground is the second floor window?
A. about 12 feet B. about 6 feet
C. about the height of an average manD. nearly 10 feet
3. According to the passage, windows are _______ of escaping a fire.
A. the only way B. the best way
C. safer than any other ways D. one of the possible ways
4. The writer suggests that ________.
A. breathing in smoke might be harmful
B. smoke will enter the room through an open window
C. fresh air can’t reach the second floor window
D. to keep you head low will help to escape a fire
5. If you are on the second or third floor when a fire breaks out, you’d better ______.
A. drop directly onto the ground
B. first drop onto a roof then onto the cement
C. drop from a roof window then onto bushes or trees
