1 . How to Start a Garden in 2024?

Gardening is a powerful outlet for creativity, enabling you to surround yourself with beauty. It can provide homegrown food for your family, keep you in touch with nature and is also an invaluable form of exercise.     1     Here are some essential tips for beginners in gardening.

It all starts with good soil. Whatever you’re growing, fertile soil is the key. Investing in rich soil initially creates a suitable environment.     2    

Grow vegetables that keep on giving. If you’re a newcomer, choose ones you can harvest more than once. Lettuce and basil are quick and easy to grow.     3     Vegetables like these mean continuous harvests, which is huge for keeping spirits high.

    4     Some plants will grow tall and some will grow closer to the ground. Tall plants will shade shorter plants and prevent them getting needed sunshine. Also, give little seedlings plenty of room to stretch and grow. If they grow too close together, don’t be afraid to thin seedlings.

Save money with seeds and cuttings. Buying all of your plants from the garden center is expensive. However, you can grow a huge range of plants from seeds or cuttings. Reach out to friends and family who garden and ask them to share spare seeds with you.     5     It takes longer than buying young plants, but it is definitely more satisfying and you will learn so much.

A.Plant for every season.
B.Size up your growing space.
C.They’ll replace their leaves every time you cut them.
D.In short, gardening is beneficial to both body and soul.
E.Choose a container size appropriate for what you are growing.
F.It promotes root development, supplying nutrients for plant growth.
G.Also check to see if they have any plants you can take cuttings from.

文章大意:本文是一篇说明文。文章介绍了科学家们对植物对声音的感知和反应一直在进行研究,近期的研究显示植物可以对不同的声音做出反应,识别出有害的振动,产生更高水平的防御性化学物质。基于该研究结果,科学家们认为声波可以作为一种无污染的替代方法来保护农作物免受昆虫的侵袭。

2 . Scientists have been experimenting with playing sounds to plants since at least the 1960s, during which time they have been exposed to everything from Beethoven to Michael Jackson. Over the years, evidence that this sort of thing can have an effect has been growing. One paper, published in 2018, claimed that an Asian shrub known as the telegraph plant grew substantially larger leaves when exposed to 56 days of Buddhist music — but not if it was exposed to Western pop music or silence. Another, published last year, found that marigolds and sage plants exposed to the noise of traffic from a busy motorway suffered growth difficulty.

Plants have been evolving (进化) alongside the insects that eat them for hundreds of millions of years. With that in mind, Heidi Appel, a botanist now at the University of Houston, and Reginald Cocroft, a biologist at the University of Missouri, wondered if plants might be sensitive to the sounds made by the animals with which they most often interact. They recorded the vibrations made by certain species of caterpillars (毛毛虫) as they chewed on leaves. These vibrations are not powerful enough to produce sound waves in the air. But they are able to travel across leaves and branches, and even to neighbouring plants if their leaves touch.

They then exposed tobacco plant — the plant biologist’s version of the laboratory mouse — to the recorded vibrations while no caterpillars were actually present. Later, they put real caterpillars on the plants to see if exposure had led them to prepare for an insect attack. The results were striking. Leaves that had been exposed had significantly higher levels of defensive chemicals, making them much harder for the caterpillars to eat. Leaves that had not been exposed to vibrations showed no such response. Other sorts of vibration — caused by the wind, for instance, or other insects that do not eat leaves — had no effect.

“Now speakers with the right audio files are more often being used to warn crops to act when insects are detected but not yet widespread,” says Dr. Cocroft. “Unlike chemical pesticides, sound waves leave no dangerous chemicals.”

1. What can we learn about plants from the first paragraph?
A.They may enjoy Western music.B.They can’t stand Buddhist music.
C.They can react to different sounds.D.They can make different sounds.
2. What’s the basis for Appel and Cocroft’s research?
A.Plants can make a cry for help.B.Plants evolve alongside insects.
C.Plants are sensitive to the sounds.D.Plants have been studied for years.
3. What can we infer about plants from Paragraph 3?
A.They can recongnize harmful vibrations.B.They look like laboratory mice.
C.They can threaten the caterpillars.D.They can release poisonous chemicals.
4. What does the last paragraph mainly talk about?
A.Disadvantages of chemical pesticides.B.Application of the experimental results.
C.Interaction between plants and insects.D.Warning system of widespread insects.

文章大意:这是一篇说明文。文章介绍了现在的樱桃、香蕉和苹果等水果相较以前味道不同的情况,并说明水果的甜味会导致健康问题。

3 . Bred to be more sweeter, today’s cherries, bananas and apples taste different than they used — to but not necessarily better. Among fruit farmers, the word “quality” is now routinely used as a standard for “high in sugar”, though firmness, color and size are also considerations. In a recent study about ways to enhance the sweetness of fruit using “molecular (分子的) approaches”, a group of plant scientists wrote that, in general, the sugar content of many fruits are now higher than before owing to continuous selection and breeding. Modern apple varieties, the scientists stressed, were on average sweeter than older ones.

The sweetness of fruit depends not just on how it is bred but also on growing conditions, yield and harvest. The lead researcher, Sugiura, said, “If you could taste an apple harvested 30 years ago, you would feel the difference.” He believed that modern apples are picked so early that even if they are bred for sweetness, they often don’t develop their full character. The fragrance (香味) never develops in fruit that is harvested too early.

Jim Cooper, an apple farmer in England, is regretful to admit the fact that many people will never taste the “strawberry hint” in a really ripe Pearmain, a type of heritage apple. In a way, the rise of consistently sweeter fruit in our lifetimes has been a victory of plant breeding. After all, it’s a rare person who would seek out bitter grapes if they could have sweet ones instead.

But the sweetness of modern fruit is not without its problems, especially for people with diabetes (糖尿病), who have to reduce their intake of higher-sugar fruits. Fruit that is bred sweeter also tends to be lower in the chemicals that make it healthy. Considering health, maybe the real problem with modern fruit is that it has become yet another sweet thing in a world with sugar. Even grapefruits, which used to be quite bitter, are sometimes now as sweet as oranges. If you’ve never tasted a sour cherry, how can you fully appreciate a sweet one?

1. In what aspect is many fruits different from before?
A.Sugar content.B.Soft skin.C.Bright color.D.High yield.
2. Why did Sugiura express discontent with the present fruits?
A.They are bred too early.B.They taste so sweet.
C.They are losing a good flavor.D.They need a higher yield.
3. What is Cooper’s attitude towards modern fruit breeding?
A.Favorable.B.Critical.C.Ambiguous.D.Indifferent.
4. What does the last paragraph mean?
A.It’s a wise choice to breed fruits for sweetness.
B.Breeding sweet fruits improves the quality of fruits.
C.Some fruits like grapes and cherries taste the same.
D.The sweetness of fruits will cause health issues.

4 . 阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。

Indoor plants are a beautiful way to    1    (bright) up your home, especially in the gray    2    (month) of winter. But there can be a dark side to houseplants if you have children or if children visit your home. It is important that you know which plants are poisonous to children.

Gardening expert Jessica Damiano    3    (recent) wrote about the issue for The Associated Press. She said she often pointed out houseplants in homes that should     4    (keep) out of children’s mouths. Last week, Damiano    5    (visit) her cousin’s home and saw a Dieffenbachia plant in the kitchen. Her cousin told her that her young son,    6    had just begun crawling, had shown interest in     7    leaves. Damiano had to explain to her cousin that eating a small amount of the plant’s stem could cause temporary     8    severe pain. The plant parts can cause throat and mouth swelling. The plant’s sap can cause nose, skin and eye pain. Damiano wrote that parents should teach their young children not to put non-food plant parts into their mouths. “Parents should also educate     9    (they),” she said. She urged parent store search whether the plants in their homes are safe to grow around children. She also suggested     10    (learn) the official botanical names of any houseplants so that they can be able to provide that information quickly to a poison control expert, if needed.

文章大意:这是一篇说明文。文章主要介绍了水培种植作物的方法。

5 . If you’re interested in growing a small food garden at home, hydroponic (水栽法的) gardening provides a way to grow fresh, nutrient-rich food in a quickly-changing world with limited resources.

What is a hydroponic garden?

    1     Plants can grow indoors, year round, in less space than traditional soil- based gardens in it. This means if you live in a tiny apartment or don’t have an outdoor area, you can still grow fresh food.

How does hydroponic gardening work?

Plants need sunlight, water and nutrients to grow.     2     But the basis of hydroponics is rooted in growing the food in nutrient-enriched water. A hydroponic system can be programmed to ensure a plant receives sufficient water, nutrients, light and even the correct PH level to provide each plant with what it needs to survive and thrive.

What plants can grow hydroponically?

A variety of different foods can be grown in a hydroponic garden.     3     Similar to what you can grow in a backyard hanging garden, the more popular vegetables grown in hydroponics include leafy greens and lettuces (生菜) . However, more complex systems can produce fruiting vegetables such as tomatoes, cucumbers, peppers and more.

    4    

In addition to being able to grow food without soil and in small spaces, hydroponic gardening can contribute to solving social and environmental issues. In regions where people don’t have access to fresh vegetables, a hydroponic garden can be part of the solution. Hydroponic plants can grow 40% to 50% faster and produce 30% more than the plants growing in soil.     5     In some cases, you can grow produce that is even more nutrient.

A.Typically, plants get nutrients from soil.
B.What produce can a hydroponic garden offer?
C.What are the benefits of a hydroponic garden?
D.A hydroponic garden uses water instead of soil.
E.Microgreens are among the easiest plants to grow.
F.You can grow more produce in a shorter amount of time.
G.You can purchase a ready-to-go hydroponic garden or build your own.

文章大意:这是一篇说明文。文章讲述了来自内蒙古通辽的一名退休教师华维光,爱好摄影。十年前,他发现家乡周围的沙地来了很多治沙工人,便开始用相机记录。在他的镜头下曾经的枯木黄沙开始出现绿意。渐渐地,草木茂盛,黄沙难寻。
6 . 阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。

Hua Weiguang,     1     retired teacher from Tongliao, Inner Mongolia Autonomous Region, is a photography enthusiast.

A decade ago, the arrival of tree planters     2     (catch) Hua’s attention and the photos of the tree planters     3     (take) by Hua are evidence of the     4     (remark) transformation of the land. In those photos, hats, scarves and goggles, for the workers fighting desertification, are basic necessities to protect them     5     the wind and sand. There was no way to avoid the brutal summer heat in the land so the workers had to lie down on the ground or curl up in the narrow shade of their cars to cool off. And they also had to eat their lunch amid the blowing sands, taking in the small pieces of sand with their food.

    6     we don’t fool the tree, it won’t fool you. You take it     7     (serious), and then it behaves in the same way to you. You put efforts to make it live, and the tree lives up to your     8     (expect),” the planters say.

China’s forest resources have increased by over 70 million hectares in the past decade,     9     (rank) first in the world. One tree after another, a green Great Wall has been built. Brush by brush, a green field     10     (paint) over the yellow sandy land up to now.
