Like China’s Kunming Institute of Botany, the Millennium Seed Bank(MSB)shines brightly for plant preservation. Located at the Wakehurst wild botanic garden in West Sussex, England, the Millennium Seed Bank (MSB), the world’s     1     (large)seed bank, has announced that it now holds more than 40, 000 wild plant species.     2     the aim of preserving rare, threatened and important wild plants, MSB     3     (create)by researchers from London’s Kew Gardens more than 20 years ago. Now around 2. 4 billion individual seeds from 190 countries are stored in     4     (it) underground rooms. Any seeds that arrive at MSB are dried, cleaned     5     then stored at-20℃. Scientists remove the seeds every 10 years     6     (see) if they can still grow into plants, and to develop new ways of       7     (help) wild plants survive. One of the most remarkable     8     (strong) of MSB is that it serves as a global backup for plant variety. Seeds in the bank include the world’s smallest water lily, a rare Australian pea and Antarctic hair grass, one of two flowering plants     9     grow in Antarctica. The bank ensures that if plants in the wild become extinct, they can be regrown from MSB seeds. There is no doubt that the MSB plays an     10     (extreme) important role in protecting the varieties of plant species on Earth.

Scientists in Florida have     1     (successful) grown plants in moon soil collected during NASA’s Apollo missions (任务) in the 1960s and 1970s.

    2     NASA-supported study at the University of Florida used soil collected by astronauts    3     (grow) Thale Cress 2 (拟南芥). To compare results, plants were also grown in Earth soil    4     was made to be similar to moon soil. The researchers     5     (add) water and then seeds to the soil, as well as daily nutrients (营养物). After just two days, their growth started.

According to Professor Anna-Lisa Paul, all the plants looked the same     6     the sixth day. After the sixth day,     7    , it was clear that the plants growing in moon soil were not as healthy as those growing in Earth soil.

DNA testing showed that those Thale Cress 2     8     (plant) in the moon soil were under stress. It was also found that the plants grew in different ways in soil from different parts of the moon. The soil collected during the Apollo 11 mission had been on the moon’s surface several billion years     9     (long) than the other soil, and the plants grown in it were the weakest.

NASA Administrator Bill Nelson believes this research will help future space missions and that resources on the moon and Mars     10     (need) to develop food for astronauts living and working in space.

When it comes to cacti (仙人掌), we usually think of them living in very dry environments like deserts. However, the plant can now be seen in some Alpine regions of Switzerland and Italy - mountain areas     1     used to be covered by snow.

“In some parts of Valais, we estimate that the cacti can take     2     one-third of the surface,” Yann Triponez, a biologist working in Valais, Switzerland said. Although the plant     3     (be) present in the local area since the late 18th century, recent     4     (discover) showed that cacti are growing faster than usual. “When you have these cacti, nothing else grows,” Triponez said, stating that the plant     5     (cover) the soil and prevents other plants from taking root.

A warmer climate in Alpine areas can be seen     6     a reason for the change. The warming climate has been reducing snow coverage in the area,     7     (give) more soil for the cacti to grow on. It also leads to     8     (long) time periods for the plant to grow. Botanist (植物学家) Peter Oliver Baumgartner told The Guardian that     9     people may have the impression that cacti prefer hot climates, they can live in temperatures as low as-15C. Baumgartner also called on more attention     10     (pay) to local biodiversity since Valais has about two-thirds of the total plant species in Switzerland.

The record of the    1    (tall) tree in Asia has been refreshed this week, as a team of Chinese researchers announced     2    (recent) that they discovered a giant cypress(柏树)measuring 102.3 meters in Tibet.

The record-breaking high tree, called Cupressus torulosa(西藏柏木),    3    (find) at the national nature reserve of the Yarlung Zangbo Grand Canyon in Bome county, Nyingchi city, during a scientific investigation led by Peking University in May.

    4    (use) drones and laser radar to map the local cypress aggregation area, the team members confirmed the     5    (present) of the 102.3-meter tree. Besides, they detected a large number of trees over 85 meters high, including 25 over 90 meters. The findings have also contributed    6    the region having the highest density of giant trees in China and Asia after precision measurement, said Ren Yu,    7    is a team member from Peking University.

Mainly distributed in southeastern Tibet, Cupressus, torulosa has a narrow distribution area and     8    small population. Therefore, it has been listed    9    a national first-class protected plant.

The previous China tree height record     10    (hold) was an evergreen fir(常绿冷杉) measured at 83.4 meters by scientists in Tibet last year.

Apples are ready to pick when the skin color deepens and the fruit comes away     1     (easy) from the tree. The presence of windfalls (风吹落的果子) is a good     2     (indicate) that fruits are ready to pick. Not all apples are ready     3     the same time, so pick regularly as most of them are fully developed.

To pick an apple, cup it in your hand, lift, and twist gently. It should be separate from     4     (it) end. Always touch apples gently     5     (avoid) injuring them, and never tug (拽) an apple from the tree     6     you may damage the fruiting spurs (枝丫) or cause apples nearby to drop.

Early season apples are eaten best soon after     7     (pick) as they don’t store (储藏) well. Midseason apples will store for a few weeks, and late season apples should be good for up to six     8     (month). Apples chosen for storage must be in perfect condition. Check stored apples regularly and remove the ones that     9     (be) going soft, brown, or rotting,

Store your apples in a cool but frost-free, dark, well-ventilated place such as a shed or garage. Make sure they don’t touch, or else wrap them in newspaper. Different species store for different lengths of time — keep them separate and use those     10     have a shorter storage life sooner.

Yuan Longping, Father of Hybrid Rice,     1     passed away on Saturday at 91, will be long remembered as one of the most honorable leaders, the World Food Prize Foundation said.

Yuan was a co-winner of the 2004 World Food Prize, the top international honor recognizing the deeds of     2     (individual) who have advanced human development by     3     (improve) the quality, quantity and availability of food in the world. Yuan shared it with Monty Jones, an African rice breeder.

Yuan’s pioneering research has     4     (complete) helped transform China from food shortage to food security within three decades, according to an earlier statement     5    (release) by the WFP.

Barbara Stinson, president of the WFP Foundation, said Yuan was credited not only for hybrid rice, but also for the ability     6    (change) land out of rice production and into other kinds of food production, including fish ponds, other fruits and vegetables, increasing the nutritional content of food in China, and contributing     7     the reduction of hunger and poverty as well.

Yuan started hybrid rice research in 1964 and     8    (succeed) in developing the world’s first high-yield hybrid rice strain in 1973. So far, its annual growth area     9    (reach) 8 million hectares (公顷)in countries including India, Bangladesh, Vietnam) Brazil and the US.

“He’s made such     10     powerful contribution. Professor Yuan will be long remembered. ” Stinson told China Daily.
