2 . Have you imagined making an attractive garden which will be the reason for your neighbors’ envy?

    1     But not every one of them has the talent for making it happen. However, if there’s one thing they DO know, it’s how to make a simple cup of tea. As for the used teabags, most of them find they’re on the landfill site, but no longer! Your used teabag can work wonders in your garden by your simply burying it.     2     Continue to read what it does.

If you have ever tried to grow some seedlings (幼苗), then you know that this can be quite challenging. Not all seeds can grow into seedlings, even though you have tried so hard. But don’t worry. Here is good news.     3     And what you need just involves a used teabag.

By burying a teabag in your garden, you will provide nutrition to the soil, offering necessary food to the plants. In this way, your plants will be healthier and grow quicker. This is because tea works as a natural fertilizer (肥料) for the soil. The teabag itself is usually made from fibres from the abaca plant, which is a type of banana plant. The bag breaks down with its contents.     4    

If you bury a teabag close to the roots of your plants, it will help store water in the soil. If there’s one thing important for plants, it’s water! What’s more, weeds are not wanted in your garden.     5     By burying a used teabag in the earth, you’ll make it a lot harder for the weeds to grow alongside your healthy plants.

A．A teabag is a great answer.

B．It does work though it sounds strange.

C．Making a beautiful garden requires efforts.

D．A beautiful garden is something most people enjoy.

E．There is one way to help your seedlings grow better.

F．A simple teabag is likely to do wonders for your seeds.

G．That will create a healthy environment for plants to grow in.

3 . Why wouldn’t scientists want to try and save the world’s largest flower, especially when it, Rafflesia, is their country’s national flower? However, when you add to the fact that the world’s largest flower is also the world’s smelliest, then suddenly the “panda of the plant world” begins to look more like a headache.

Sofi Mursidawati, a PhD in agriculture at the Bogor Botanical Gardens on the island of Java, is one of the world’s leading experts on this strange flower, and her efforts to build a body of knowledge that will allow for the creation of the flower into the future could save it from extinction. Rafflesia has no leaves, roots, or stems, but rather only one giant, one-meter-long, 20-pound bloom that smells like rotting meat. Found only in the rainforests of Sumatra and Borneo, its artificial creation in the face of habitat loss is a problem.

With seeds the size of grains, pollinated flowers infect a kind of vines(葬本植物) called Tetrastygma, before slowly growing over many months into an enormous cabbage一sized bulb. The curiosities don’t end there. In fact, it barely qualifies as a plant. It branched away from having genetics that code for photosynthesis(光合作用) millions of years ago, and relies entirely upon its host —the vines for energy.

Just as it’s difficult to get pandas to breed, Rafflesia is a pain in the neck, as the blooms last only a week. After collecting Rafflesia seeds, and a variety of Tetrastygma vines, it took Mursidawati four years to welcome the first smelly flower into the Bogor Botanical Gardens. A decade later, the work was still slow going. However, the creation is doing one thing very well：creating specimens(样本) to send to botanic gardens around the world, creating what will likely be the strange flower’s greatest chance for survival.

B．Simple.

C．Attractive.

D．Challenging.

2. What can we learn from paragraph 2?

A．Rafflesia is different from common plants.

B．It’s a problem for Rafflesin to live in the rainforests.

3. Where does Rafflesia get its energy?

A．From the sun.

B．From its host.

C．From the earth.

D．From the air.

4. Which of the following is a suitable title for the text?

A．The World’s Largest Flower Is Endangered.

B．Raflesin Becomes World’s Largest Flower.

C．Woman Scientist Creates Various Flowers.

D．Woman Scientist Races to Save World’s Largest and Smelliest Flower.

4 . The rapid pace of global warming and its effects on habitats raise the question of whether species are able to keep up so that they remain in suitable living conditions. Some animals can move fast to adjust to a swiftly changing climate. Plants, being less mobile, rely on means such as seed dispersal(传播) by animals, wind or water to move to new areas, but this redistribution typically occurs within one kilometre of the original plant.

When the climate in a plant’s usual range becomes hotter than it can tolerate, it must find new, cooler areas that might lie many kilometres away. One explanation for long-distance seed dispersal is through transport by migratory (迁徙的) birds. Such birds swallow seeds when eating fruit and can move them tens or hundreds of kilometres outside the range of a plant species.

Gonzáiez-Vary and colleagues report how plants might be able to keep pace with rapid climate change with the help of migratory birds. The authors analysed the fruiting times of plants, patterns of bird migration and the interactions between fruit-eating birds and fleshy-fruited plants across Europe. Plants with fleshy fruits were chosen for this study because most of their seed transport is by migratory birds, and because fleshy-fruited plants are an important part of the woody-plant community in Europe. The common approach until now has been to predict plant dispersal using models fitted to abiotic (非生物的) factors such as the current climate. Gonzáiez-Vary instead analysed an impressive data set of 949 different seed-dispersal interactions between bird and plant communities, together with data on entire fruiting times and migratory patterns of birds across Europe. The researchers also analysed DNA traces from bird wastes to identify the plants and birds responsible for seed dispersal.

1. How do species adapt to climate changes when it’s too hot?

A．All animals will move away across great distanced.

B．Some plants depend on migratory birds to carry seeds.

C．Some plants depend on animals, wind or water to move.

D．Plants’ seeds disperse to cooler places of several kilometres away.

2. Why did researchers mainly study fleshy-fruited plants?

A．Most of these can’t fit rapid climate change

B．Migratory birds like making nests in them

C．Migratory birds transport their seeds.

D．They are favoured by most birds.

3. Why does the author mention “fleshy fruits” and “fruiting times” in paragraph 3?

A．To explain relations between fruit plants and migratory birds.

B．To clarify the reason why birds migrate in fruiting times.

C．To present a fact that migratory bird eats flesh fruits.

D．To show that fruits depend on migratory birds.

4. What is the text mainly about?

A．The advantage of fruit plants.

B．The destination of the bird migration.

C．The adaptation of fruit plants to the climate change.

D．The influence of climate change on plants and animals.

5 . Many people like to plant different plants. Whether sowing seeds (种子) indoors, or directly into your garden, you may want the seeds to germinate (发芽) early.     1    .

A good garden needs good seeds. In order to achieve good germination rates, you need quality seeds. Of course, you can save your own seeds from heritage crops. But if you are buying seeds, you always need to consider the source.    2    . That can make you choose the seeds suitable for growing in your area.

    3    . Once you have your seeds, remember that you will also have to store them correctly. Then you will have to make sure that you provide the seeds with environmental conditions they need to germinate successfully. Increasing germination rates by improving conditions can increase the production.

Seeds require water for germination. Mature seeds take on significant amounts of water before they can begin the germination process. As the seeds take in water, they begin to break down the food stored within the seed. The amount of water required will depend on the type of seed you sow.     4     , germination cannot take place. But watering too much can also cause a range of issues.

Seeds require oxygen for germination. Before seeds develop leaves, they need oxygen from their environment for metabolic (新陈代谢) processes to take place. So it is important to make sure that seeds are buried to the right depth.     5    , you may find it more difficult for oxygen to reach them. Some seeds also need light for germination, so they must be placed on the surface of the soil.

A．If you water too little

B．Just believe in yourself

C．If seeds are buried too deep

D．When too much water is supplied

E．Make sure you choose seeds from an honest supplier

F．Good germination rates depend on environmental conditions

G．These simple tips can help your seeds improve germination rates

The loquat(枇杷) is native to southeastern China. The     1     (leaf) of the loquat tree bear a similarity to the pipa,     2     ancient Chinese instrument. That's     3     it shares the same Chinese pronunciation with that of the instrument. The loquat was first planted by the Chinese people 1,800 years ago and spread abroad later on.

When     4     (study) in Japan in 1988, Lin Shunquan, a Chinese professor, found that the scientific name for the loquat was “Japanese plum“ internationally     5     that it was thought to be native to Japan. Since     6     (he) return to China in 1989, Lin Shunquan has been working to correct the name of the loquat. In 1998, his paper Loquat: Botany and Horticulture was published in a     7     (profession) journal, arguing that the loquat originated in China. Since Japan     8     (acknowledge) that the loquat originated in China in 2006, the name, “Chinese plum”, has been accepted worldwide.

In addition,     9     (devote) to advancing the loquat planting techniques, Professor Lin helped to develop the loquat industry. Due to the demanding techniques of growing loquat and the high cost of labor, few young people     10     (willing) take over. Lin Shunquan has also worked with Alibaba to establish a direct base, which has attracted young people to return to their hometowns to set up online shops.

As the world    1    （large）cotton consumer and the second largest producer of cotton, China has a long history of cotton cultivation. It is worth    2    （mention）that Xinjiang cotton is highly regarded because of its high yield and high quality.

    3    （locate）in the inland of Eurasia（欧亚大陆）, Xinjiang has a typical mild continental climate. Drought, little rain, sufficient heat, big temperature    4    （different）between day and night and long day make a good growth environment for cotton.

Though Xinjiang has little rainfall, it has a large number of snow-capped mountains, from which meltwater gives cotton abundant water resource. Meanwhile,    5    contrast to the instable rainfall in the monsoon（季风）regions, mountain snowmelt has the characteristics of stable water transportation,    6    is very suitable for the growth of cotton.

Xinjiang is lightly populated and has a vast planting area. It has    7    area of 1.66 million square kilometers and a population of about 23 million. The cotton planting area    8    （cover）25,019.3 square kilometers in 2020，according to the Department of Agriculture and Rural Affairs of Xinjiang.

The combination of advantaged    9    （nature）conditions and mechanical technology makes Xinjiang cotton have good quality. Endless white cotton has also become one of the    10    （symbol）of great beauty in Xinjiang.
