Exploit your parking space

An unused parking space or garage can make money. If you live near a city center or an airport, you could make anything up to ?200 or ?300 a week. Put an advertisement(广告)for free on Letpark or Atmyhousepark.

Rent(出租)a room

Spare room? Not only will a lodger(房客)earn you an income, but also, thanks to the government-backed “rent a room” program, you won’t have to pay any tax (税) on the first ?4,500 you make per year. Try advertising your room on Roomspare or Roommateeasy.

Make money during special events

Don’t want a full-time lodger? Then rent on a short-term basis. If you live in the capital, renting a room out during the Olympics or other big events could bring in money, Grashpadder can advertise your space.

Live on set

Renting your home out as a “film set” could earn you hundreds of pounds a day, depending on the film production company and how long your home is needed. A quick search on the Internet will bring up dozens of online companies that allow you to register(注册、登记) your home for free—but you will be charged if your home gets picked.

Use your roof

You need the right kind of roof, but some energy companies pay the cost of fixing solar equipment(around£14,000), and let you use the energy produced for nothing. In return, they get paid for unused energy fed back into the National Grid. However, you have to sign(签)a 25-year agreement with the supplier, which could prevent you from changing the roof.

The year is 2094. It has been announced that a comet (彗星) is heading towards the Earth. Most of it will miss our plant, but two pieces will probably hit the southern half of the Earth.

On 17 July, a piece four kilometers wide enters the Earth’s atmosphere(大气层) with a massive explosion. About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned.

Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the earth are already dead, but the north won’t escape for long. Because of the explosions, the sun is hidden by clouds of dust, and temperatures around the world fall to almost zero. Crops are ruined. The sun won’t be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million remain alive.

Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn’t live through the cold climate that followed and they died out. Will we meet the same end?

A. An event of imagination.

B. A scientific adventure.

C. A research on space.

D. A historic discovery.

2.When the first piece hits the South Atlantic , it causes _____

A. an earthquake B. damages to cities

C. an Earth explosion D. huge waves

3.Why can’t the northern half of the earth escape for long?

A. Because the light and heat from the sun can not reach the earth.

B. Because the land is covered with water

C. Because people there can not live at the temperature of zero.

D. Because wars break out among countries.

4.By giving the example of dinosaurs, the author tries to prove______

A. the Earth could be hit by other objects in space

B. what happened 65 million years ago was an invented story

C. the human beings will die out in 2094
