  Common indoor plants may prove to be a valuable weapon in the fight against rising levels of indoor air pollution.Those plants in your office or home are not only pretty, but NASA scientists are finding them to be surprisingly useful in absorbing possible harmful gases and cleaning the air inside modern buildings.

  NASA have announced the finds of a 2-year study that suggested the common indoor plants may provide a natural way of helping fight against “Sick Building Syndrome(综合症)”.

  Research into the use of biological processes as a means of solving environmental problems, both on Earth and in space habitats, has been carried out for many years by Dr.Bill Wloverton, a senior research scientist at NASA.

  Based on preliminary evaluations(初步评估)of the use of common indoor plants for indoor air purification(净化),NASA funded a study using about a dozen popular varieties of attractive plants to determine their effectiveness in removing several key pollutants linked with indoor air pollution.NASA research on indoor has found that living plants are so efficient at absorbing pollutants in the air that some will be launched into space as part of the biological life support system aboard future orbiting space stations.

  While more research is needed, Wolverton says the study has shown that common indoor plants can remove certain pollutants from the indoor environment.“We feel that future results will provide an even stronger argument that common indoor plants can be a very effective part of a system used to provide pollution free homes and work places,” he concludes.

  “Combining nature with technology can increase the effectiveness of plants in removing air pollutants,” he said.

  NASA research has always shown that living, green and flowering plants can remove several poisonous chemicals from the air inside buildings.You can use plant in your home or office to improve the quality of the air to make it a more pleasant place to live and work-where people feel better, perform better, and enjoy life more.

Everybody staying at a certain place long enough needs to know where the toilet is . When I first visited the Divinity School Library in Yale University, I tried to find the 1 with words familiar to me such as WC, Ladies, Bathroom and Washroom, etc.I used all the 2 I had about toilets ,but I could not find 3 . My common sense told me that there 4 be toilets in the library, so I 5 trying Finally ,I found a door on which was a single 6 :WOMEN. 7 it did not look at all like a toilet, I thought it must be one. And because I couldn't 8 any longer, I had to try it .As I 9 the door, I was sure I made a 10 ,so I came out immediately. 11 what I had entered was a room much 12 than my living room in Beijing , with a 13 lamp by a table on a beautiful green carpet. On one 14 of the room, there was a very comfortable brown sofa. 15 it there was a mirror on the wall up to the 16 .There were two 17 sofas, by the side of the table. In one corner was a clothes hanger and in another 18 was a big pot of green plants.It 19 a big sitting room in a hotel .There was no sign of a 20 .But it was the only 21 place a toilet could be. Then I remembered that there was another door in the room , so I went back in and opened the door. And there it was ! I found it 22 ! The toilet room was only half the size of the outer room.It had only two seats. Then ,another question came to me :since it was impossible for such a big library to have only one toilet ,I had to ask someone about toilets. A “Rest Room”is also a toilet.The “rest room “had only one seat ,and both women and men could use it by 23 the door from inside.

The term “rest room” is miles apart from the Chinese 24 of a toilet. Here at Yale, when I use a “women”, I feel myself a queen.And when using a “rest room”, I do have a 25 of rest, because it is clean and has a window with a beautiful view.

“Rain Check” now means a second 13 at something. Often ,a rain check has nothing to 14 with rain.

Stores may offer “rain checks “ 15 they sell out all of a product a television set , for example 16 a special low price. After all the TV sets are 17 , the store gives rain checks to 18 who wanted to buy one. The rain check allows a person to buy the TV set later, at the 19 low price, after the store receives some 20 from the factory.

“Rain Check”also is used in social 21 .It’s a way of 22 aninvitation, but for a later time.

You may ask for a “Rain Check” if you are 23 to a friend’s house for dinner, but can’t be there. You say ,“I would love to 24 you for dinner, but I’m busy. Could I have a rain check?”You are asking , in other 25 ,if you could join your friend for dinner at another time.
