8 . Bottle gardens are loved by many people. What’s a bottle garden? A bottle garden is exactly what it sounds like: a tiny garden planted in an object like a bottle._
By following some tips, you’ll have your bottle garden planted and thriving (茁壮成长) in no time. The first step in creating a bottle garden is selecting (挑选) the bottle. Clear bottles can allow the most sunlight to enter.
Then you should keep in mind that bottles with openings big enough to fit your hand through can make planting easier.
When the bottle is ready, put inside some rich soil and plants suitable for a bottle garden. Once you grow the plants in the way you like, remember to place your bottle in a bright space which won’t have direct sunlight. East-facing windows often work well for this purpose.
A.How do the bottle gardens work? |
B.Such gardens don’t have a very long history. |
C.They make thoughtful and eco-friendly gifts. |
D.Why would anyone want to grow a garden in a bottle? |
E.If you choose a colored bottle, select plants that prefer low levels of light. |
F.If not, you’ll have to use tools to work the soil and plants inside the bottle. |
G.You can also use a grow light if your home doesn’t have any suitable windows. |

A.Its trunk sometimes measures more than ten metres in diameter. |
B.Its trunk is thicker at the top than at the bottom. |
C.Its branches near the top are longer than those near the ground. |
A.Its leaves. | B.Its trunk. | C.Its skin of the tree. |
A.Its empty trunk can be used by people to build everything. |
B.Its flowers can turn into a kind of cucumber. |
C.Its leaves and branches can keep the rain water cool and clean. |
A.The baobab—unusual but useful. |
B.The baobab—a tree that people can make good use of. |
C.The baobab—a strange tree that can make ropes. |
10 . High-resolution (高分辨率) satellite imagery has been used to map every single tree in Africa, showing a technique that could help improve the monitoring of deforestation (森林砍伐) across the world. Florian Reiner at the University of Copenhagen, Denmark, and his colleagues used images from sate lies to map canopy (树冠) across the entire African continent.
Modern sate lies usually catch tree canopies at a resolution of 30 meters — fine for measuring the size of forests, but less good at mapping individual trees. The satellite data Reiner and his colleagues used had a resolution of 3 meters, enabling the study to map all trees, including those not part of a forest.
The results suggest that 30 percent of all trees in Africa aren’t in a forest and instead are across farmland, savannah and urban areas. “Many countries in Africa lack thick forests, but have a lot of trees.” says Reiner. “These trees are extremely important to the local ecosystems, the people and the economy. By tracking every single tree, researchers can start to monitor how these trees are coping with climate change or whether they are sensitive to deforestation.” It could also improve the monitoring of reforestation efforts, which are growing in popularity as a way of removing carbon dioxide from the atmosphere.
“At a local level, being able to consistently monitor when and where trees are disappearing or reappearing can lead to more actionable insights,” says John Francis at the Alan Turing Institute in London.
“The study is a proof of concept rather than a map ready for immediate commercial use,” says Reiner. “It’s research work. It’s showing what could be done,” he says. But he is already working with colleagues to scale up the tracking approach to cover the entire global canopy: “We’re hoping that this will be seen as a way forward in monitoring tree resources.”
