2 . Many people want to grow their own food in their own backyard, but they don’t know how to start. This article will teach you how to start!

Find out what plants to get. Get plants that can grow in your area, and make sure you plant them at the right time of the year.     1     Usually you should start your garden after the last frost date in the spring t While they’re technically fruits, a good starter plant to grow is tomatoes. You can plant these in a pot or in your garden.

    2     Make sure there is enough space to grow your plants. Use a tiller (犁) and till the whole space you will be gardening. Then pull out any weeds and move any large rocks. Find out how big your plants get and space them accordingly. If your plant needs slightly acidic (酸性的) soil, get an acid metre and make sure the soil has enough acidity.     3     To grow them well, you can buy fertilizer that can add acidity to the soil.

Buy your plants and fertilizers. You can either get seeds or get plant seedlings. Go to your local nursery and see what they have. Get fertilizer as well.     4     This will make your plants grow, better and faster!

Plant your plants in the garden. Use a hand shovel and dig a small hole big enough to put your plant in. Water your plant before you put it in so you can wet the root ball. Sprinkle (撒) in a little bit of fertilizer and put your plant in.     5    

For seeds, stick your finger into the dirt where you want to plant the seed until the dirt reaches the second joint on your finger.

A．Learn how to start a garden.

B．Plan out your garden wisely.

C．Make sure to get the right fertilizer for your plants.

D．Some plants that need acidity are tomatoes and blueberries.

E．You should grow and water them in spring if you want to have a good start.

F．Then surround the plant with dirt and make a small circle around it for water.

G．If you plant them too early or too late, they could freeze and die before you can harvest vegetables.

3 . Keeping plants at home is a healthy and comfortable way of life. The following houseplants can create a most beautiful piece of green for your home.

Bird’s Nest Fern (蕨)

The bird’s nest fern is a good choice for anyone with a house that wouldn’t support sun-loving species. It’s a hardy fern variety adapting to living on forest floors, where the air tends to be cool and damp. It likes to be misted as well, but this doesn’t always mean you need a misting bottle—spraying (喷洒) it in the sink or hanging it near a shower often works as well.

Chinese Money Plant

This is a flowering species that might be most appropriate for experienced plant gardeners looking for a new challenge. It prefers a moderate amount of indirect light, and tends to dry out slightly between watering sessions. It produces new plants easily without any input, directly from its root system. These can coexist in the same pot for a time.

Resurrection Plant

This native of the Mexican desert has adapted to surviving in extreme drought by curling (蜷缩) into a ball and remaining in seemingly lifeless state for years, if necessary. In this form, it can be transported by the wind across the dry landscape to areas with water. It will revive within hours in a shallow bowl of water, unfolding and transforming into a fresh and green moss (苔藓).

Snake Plant

This is a striking houseplant that can be an especially good option for new plant owners who you might not trust to keep a plant alive. It grows happily in almost any condition. While it prefers bright light, it doesn’t mind shade or even artificial light. Plus, thanks to its thick, fleshy leaves, it stores water with remarkable efficiency, which makes it survive without water in the earth.

3. What do resurrection plant and snake plant have in common?

A．They demand attentive owners.	B．They are very drought-tolerant.
C．They will curl for self-protection.	D．They can store water for drought.

4 . There are a number of animals that give off light in some way-including several kinds of insects and fish. Some kinds of mushrooms give off light, too. But most plants don’t give out light. Now, scientists are working to change that.

When a living thing gives off light, it’s called bioluminescence (生物发光). Fireflies are a well-known example of bioluminescence. Though less well-known, many mushrooms are also bioluminescent. These bioluminescent creatures light up thanks to the chemicals called luciferins (荧光素)inside their bodies. Luciferins cause a chemical reaction that can give off light.

Plants don’t naturally have luciferins, so there are no naturally bioluminescent plants. But that hasn’t stopped scientists from trying to create them. In the past, scientists have created plants that made less bright by adding DNA from shining objects. Scientists have also created plants that can give off light by adding luciferins to plants. But it only works as long as the chemicals last. In 2017, a team was able to cause a plant to give off light for about four hours.

Now, researchers at a Russian company have come up with a new method of creating shining plants. By adding certain parts of the DNA from shining mushrooms to ordinary tobacco plants, the researchers were able to create plants that could make their own luciferins. The scientists reported that the light was about 10 times brighter than in earlier shining plants.

The researchers believe that shining plants could help scientists learn more about the way plants work. For example, the moving patterns or waves of light in the plants may show activities in plants that normally can’t be seen. The shining also helps reveal how plants may be affected by things around them. For example, the plants gave off much more light strongly when a ripe banana skin was nearby. But the researchers don’t think the plants will just be used for science. They think many people may want shining plants for their beauty. So they are working with a company to develop shining plants for sale.

5 . Pacific Coast Range

Stretching along the west coast of North America from northern California to Alaska, the forests found along the Pacific Coast Range are the largest area of temperate (温带的) rainforest in the world. The forests are home to the coast redwood, the world’s tallest tree. Across the region, the forest understory (林下叶层) is wet and heavily vegetated.

Taiheiyo Evergreen Forests

Found in southern Japan, they are temperate rainforests of evergreen broadleaf trees. The forests can receive more than 100 inches of rain every year. The forests are covered by Japanese cedar and Japanese stone oak, while moso bamboo comprise the understory. The extent of the Taiheiyo forests has been reduced due to development and agriculture. Today,17%of the remaining forest is protected by national parks and other reserves.

Atlantic Oakwood Forest

The Atlantic Oakwood Forest covers the wettest parts of the United Kingdom. A species of oak tree (橡树) called sessile oak occupies the landscape. Unlike other temperate forests, these forests tend to have an open understory of grasses. Much of the historical range of the forest has given to agriculture and other development, though that has changed in recent decades.

Valdivian Temperate Rainforest

This forest is found on the west coast of Chile and Argentina, on the wet, western slopes (斜坡) of the Andes mountain range. With the coastline to the west, the peaks of the Andes to the east, and the Atacama Desert to the north, the region supports a number of plant and animal species found nowhere else in the world. Uniquely, the forest is covered by evergreen flowering trees, which are native to Chile and little known outside the region.
