Can Indoor Plants Really Purify the Air?

Plants are very important to human life. Through photosynthesis(光合作用), they transform carbon dioxide into fresh oxygen. They     1     (assume) to remove toxins from the air we breathe -- but is this true?

One famous NASA experiment published in 1989 has found indoor plants can clean the air by removing pollutants     2     cause cancer. Later research has found soil micro - organisms in the potted plant also     3     (play) a part in cleaning indoor air.

Based on this research, some scientists say house plants are effective natural air purifiers, and the bigger and leafier the plant, the better. The amount of leaf surface area influences the rate of air purification.     4     , however, say the evidence that plants can effectively accomplish this feat(功绩)is far from conclusive.

“There are no definitive studies to show that     5     (have) indoor plants can significantly increase the air quality in your home,” According to Luz Claudio, a professor of environmental medicine and public health. “There’s no question     6     plants are capable of removing volatile(易挥发的)chemical toxins from the air under laboratory conditions,” says Claudio. But in your home or office space, the notion that putting a few plants together can purify your air doesn’t have much hard science     7     (back) it up.

Most research efforts to date, including the NASA study, placed indoor plants in small,     8     (seal) environments to assess how much air-purifying power they have. “But those studies aren’t really applicable to what happens in house. In many cases, the air in your home completely turns over -- that is, exchanges places with outdoor air -- once every hour. In most instances, air exchange with the outside has a     9     (great) effect on indoor air quality than plants.” says Stanley Kays, a professor of horticulture(园艺学).

Disappointed     10     many people may be by what Kays said, the professor also made it clear that he believes house plants are beneficial. Studies have shown plants can knock out stress and make people feel happier. More research shows spending time around nature has a positive effect on a person’s mood and energy levels.

The remains of an incomplete gold mask was among the 3,000-year-old items found at Sanxingdui, an archaeological site in Guanghan, Sichuan Province.     1     (weigh) about 280 grams and estimated to be made of 84% gold,     2     mask was found at one of the newly discovered pits (深坑) at Sanxingdui.

A large number of ancient artifacts     3     (find) at Sanxingdui since the 1920s, when local farmer     4     (accidental) came upon a number of relics at the site. A major breakthrough occurred in 1986, with the     5     (discover) of two pits containing a variety of items. Six more     6     (be) then found in late 2019.

Items found at the site have helped scientists learn more about Sanxingdui and     7     (it) close connection to ancient Chinese culture. They are believed to be     8     the ancient Shu State, and crucial to our understanding of the unique civilization. Recent discoveries further confirm the theory     9     the pits were used for sacrificial (祭祀的) purposes, as many of the items found had been burned before being buried. Experts say that more research     10     (conduct) to rule out other explanations of the pits’ usage.
