2 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

When John pulled into his mother’s driveway with his young daughter, Lily, the sight of the familiar lychee (荔枝) tree welcomed them. “Look, Lily,” John said, pointing to the towering tree in the front yard. “It’s the family tree.”

Lily smiled as John treated the tree as if it were a real family member, patting its trunk (树干) affectionately. As they were admiring the tree, the screen door opened and out stepped Grandma Mei, bathed in the warm Florida sunlight. Grandma Mei, who came from the province of Guangdong in China, was known for her green thumb, particularly when it came to lychees.

Seeing her granddaughter, Grandma Mei adjusted her baseball cap and asked if Lily was ready for some lychees. But Lily hesitated, for the fruit’s appearance was unlike any other fruit she had tried before. With a laugh, Grandma Mei gave her a gentle hug. “More lychees for me then, John,” Grandma Mei said.

“Let’s get busy!” John said with enthusiasm, rubbing his hands together. “Family tree’s waiting.”

Hearing Dad calling the tree by name, Lily couldn’t help laughing. “Laugh if you want, Lily, but this tree is really family. On cold nights, before family tree was fully grown, Grandma Mei used to take my blanket and throw it over that tree.” Grandma Mei nodded, adding that she had to protect the tree from bad weather so that it would become a big strong tree and grow fruit for the whole family.

John, eager to start the day’s work, began climbing the tree, determined to harvest the best lychees for the family. Lily watched in amazement, noticing the clusters (簇) of lychees, their skin rough yet inviting.

As John skillfully cut through the branches with a cutter, Lily expressed her concern for the well-being of the tree. John explained to her that cutting the ends of branches won’t hurt family tree. Instead such behaviour made it healthier and stronger.

注意：

3 . Increased human activity and climate change have caused a rise of algae (藻类植物) in water bodies around the world—sometimes choking ecosystems of sunlight and oxygen. In more extreme cases, they can produce dangerous poisons that can sicken or kill people and animals. But the plenty of algae could prove crucial as our population rises beyond eight billion people worldwide because algae are crops that don’t need land, freshwater, or fertilizer to fill nutritional gaps.

And even though they are so closely associated with human’s bad impact on Earth, algae could also play vital roles in slowing climate change and helping fight against pollution, viruses, and more. With microplastic pollution documented in almost all habitats related to water, a study showed that algae can help filter microplastics from water. Algae can also filter chemicals that can be used for fertilizer.

Algae can produce more effective biofuel than traditional sources. Rescarchers at a German algae growing facility are already using it to fuel plane. Researchers believe this and other sustainable fuels could reduce carbon released from airplanes by up to 80 percent.

Animal feed containing a kind of red algae reduces harmful methane(甲烷)released from cattle by more than 80 percent. The addition works by changing the environment in a cow’s stomach, stopping the production of methane before it can be released.

Red algae can stop the copies of some viruses, and have been shown to stimulate the body’s immune (免疫的) system and could become a powerful anti-HIV medicine.

In 2019, freshwater algae were launched into space to change the CO² breathed out by astronauts on the International Space Station into oxygen. Since algae are also high in protein, they could replace up to 30 percent of astronaut food in the future.

1. What can we know about algae from the first paragraph?

A．Better late than never.	B．Every coin has two sides.
C．All is well that ends well.	D．Two heads are better than one.

2. Why do algae have a positive impact on environment ?

A．They avoid climate change.	B．They absorb pollutants in the air.
C．They reduce microplastics in the water.	D．They filter most poisonous chemicals.

3. What can algae help in our life?

A．Change animal feed into methane.

B．Store carbon released from airplanes.

C．Help researchers to create traditional sources.

D．Create biofuel and reduce methane in cows’s stomach.

4. How do algae benefit human’s health?

A．By helping fight against diseases.	B．By increasing human’s strength.
C．By producing more oxygen than other plants.	D．By replacing much food for astronauts.

4 . This summer, nearly 65 percent of the United States is experiencing “unusually dry” weather. More than 109 million people are living under drogue conditions.     1     So how to garden when there’s a lack of water?

    2    Newly planted trees and shrubs(灌木)should be put on the top of the watering list. They require regular watering until their roots get deep into the soil. That process can take a full year. Vegetables such as beans, cabbage, and lettuce also have high water needs. None will likely survive with little water.

Most plants require an average of 2 to 4 centimeters of water each week under normal conditions. That need could increase, however, during periods of extreme heat, when the soil dries out more quickly.     3     Divide it over two or three times per week.

Use deeper, less-frequent watering instead of daily sprinkles(洒水)which can be wasteful? Watering deeply also leads to stronger, deeper roots that are better able to support plants when there’s no surface water. So avoid using overhead sprinklers.     4     You can place watering devices on the soil directly over roots.

Consider using recycled household water, also called gray water, to water plants. Unsalted water left over from boiling eggs or vegetables provides extra nutrients(营养物). Dish and bath water that is not too soapy will not harm plants. And water captured(捕获)while cleaning fruits and vegetables can be used around the garden.     5    .

A．So learn how to water plants correctly.

B．So make good use of water in your house.

C．You should water newly planted trees regularly.

D．A lot of them have plants or yards to worry about.

E．First you should decide which plants need water the most.

F．Do not offer your plants their weekly water needs all at once.

G．They wet the leaves and other areas instead of directing water to plant roots.

5 . How to create an indoor garden

If you’re looking for a way to brighten up your home, consider creating an indoor garden.     1     We will share some basic tips on how to make yours look its best.

Know the type of plants you want

Deciding is probably the hardest part when it comes to creating an indoor garden because there are just so many plants to choose from. Start by thinking about what type of plants you want.

    2     Or maybe something that doesn’t need much attention or effort? Once you have an idea of the type of plant you want, you can start narrowing down your options.

Get the right potting soil and containers

Now that you know what type of plants you want, it’s time to get the right potting soil and containers. Make sure to get a potting mix that is specifically designed for indoor plants.     3     As for containers, you can really use anything as long as it has drainage holes.

Choose a bright location Once you have your plants and pots, it’s time to choose a location for your indoor garden.     4     This will help your plants grow and stay healthy. If you don’t have a spot that gets a lot of light, you can always use artificial lighting like grow lights.

    5    

In addition to watering, you’ll also need to add substance to your plants about once a month. This will help them grow and stay healthy. Just be sure to follow the instructions on the package. Don’t overdo it.

A．Give fertiliser monthly.

B．How exactly can we make one?

C．Follow the instruction correctly.

D．But don’t worry, we’re here to help.

E．This will help your plants grow strong.

F．Do you want something that will blossom?

G．Look for a spot in your home that gets a lot of natural light.

6 . Some people are allergic (过敏的) to tree nuts. Would it be safe for a nut-allergic person to eat baked goods with coconut or coconut oil? Here are the views of Dr. Scott Sicherer.

Despite its name, coconut is not actually a nut, but a fruit. Regardless, the Food and Drug Administration considers it a tree nut, which is why it’s included in U.S. labeling laws.

It is difficult to assess the risk of coconut allergy among those with tree-nut allergies because allergic individuals may avoid it on purpose. Still, coconut allergy appears rare, and uncommon even among those with tree-nut allergies.

In a national registry of 5,149 people with peanut or tree-nut allergies, only four self-reported an allergy to coconut. And a more recent study of 40 children with positive tests or known allergy to peanuts or tree nuts showed no increased risks for having positive tests or allergy to coconut.

Your allergist would consider your personal allergy history in deciding whether to add coconut to your diet or to perform any testing. However, be aware that tests are often positive to coconut in people who could actually tolerate it, so a physician-supervised feeding test may be necessary for a conclusive answer.

When it comes to coconut oil, there is almost no medical literature on allergic reactions to it, which may reflect the likelihood that the processed forms of coconut oil contain little or no protein, although this has not been studied. Still, for those with coconut allergy, avoidance of coconut oil should be considered because it may still have a little protein.

Finally, it’s important to note that people with peanut or tree-nut allergies who choose to eat coconut must be careful to avoid cross-contact with tree nuts or peanut being avoided.

1. What do you know about coconut from this passage?

A．It is really a nut.	B．Most people are allergic to it.
C．It is actually a fruit.	D．It is forbidden by American laws.

2. Why is it difficult to assess the risk of coconut allergy among those with tree-nut allergies?

A．They are cautious about it and avoid it.	B．They eat coconut as a kind of fruit.
C．Coconuts are becoming rarer and rarer.	D．Coconut allergy is too common.

3. What is the probable meaning of the underlined part “medical literature” in paragraph 6?

A．Stories about medicine.	B．Documents on medicine.
C．Novels for physicians.	D．Description of coconut oil.

4. Which may be a suggestion Dr. Scott Sicherer gives to nut-allergic individuals?

A．Having a feeding test regularly.	B．Trying to tolerate mild allergies.
C．Avoiding eating any coconuts.	D．Following allergists’ instructions.

7 . Growing flowers is not as difficult as it might seem at first glance.     1     All you really need to grow your own flowers is a potato, a plastic bottle, a rose, and plenty of fertilized soil. You might wonder what the potato and the plastic bottle are for. Even though this unusual combination might be strange to you, it really works incredibly well.

    2    The second step is to remove all leaves and thorns from it and give it a diagonal(斜的) cut around 3 centimeters below the head of the rose. It is important that the rose stays in shape so be careful when preparing the rose. You can then place it in a vase and store it like that for a few days.

The third step is to drill a small hole in a potato.     3     So when the rose is put in, it is tightly secured and does not move around. After you are done with the potato, you have to place plenty of fertilized soil on the bottom of a pot or a similar container.     4     Then you have to place them carefully on the soil. Once you find the right position, you have to fill up your pot with the remaining soil. The potato should be located around 5 centimeters below the surface of the soil. .

The final step is to cut out the bottom of the plastic bottle and then place it around the rose.     5    

A．It should be just the size of the rose.

B．You really don’t need to be a gardening professional.

C．First of all, you need to choose a rose you really like.

D．There is a simple trick that can be used to help roses grow.

E．Once you, have prepared the soil, place the rose in the potato.

F．Flowers are expensive, so why not grow them in your own garden?

G．Now all you need to do is water the soil occasionally and have some patience.

8 . A flower festival is an event during which many types of flowers are shown to the public. In some cases, a flower festival may be a small event attended by local people who grow plants as a hobby.

    1     They may attract large numbers of flower growers flower sellers and tourists.

Usually, a flower festival takes place at a time of year when many types of flowers are fully open.     2     In this case, the organizers must make sure that the event is scheduled during the right time of year for that type.

Some festivals are arranged to encourage flower growers to grow certain types of plants. People are invited to show their flowers at the festival.     3     Prizes are given to those who grow the largest, most colorful or hardiest (最耐寒的) plants.

Besides competing for prizes, many flower growers show their plants in flower shows for business purposes. Some people use these events to win contracts with companies that buy large numbers of flowers. Some take the chance to market flowers to customers,     4     They put their newly created plants on show at these festivals.

    5     Local restaurants provide meals and drinks for attendees. Musicians and other entertainers (演艺人员) are sometimes hired to provide attendees with pleasure. Nearby hotels and shops are full of people. They all can make a lot of money from the event.

A．There will be competitions.

B．These flowers can be very expensive.

C．Other festivals are big international events.

D．Some festivals focus on a certain type of plant.

E．Some growers have created new types of flowers.

F．Usually, some flower festivals are held in the big parks.

G．Flower festivals can also encourage local economic (经济的) development.

9 . 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。

With high yield and superior quality, Chinese hybrid rice varieties have been introduced around the world,     1     (benefit) more people. The export of China’s hybrid rice technology started many years ago. In 1979, China provided hybrid rice seeds to another country for the first time, and 40 years later, in     2     (real), China’s hybrid rice has been planted in dozens of countries in the world.

In the past 40 years, Chinese scientists     3     (devote) to providing assistance to many other countries. China has trained more than 14,000 hybrid rice professionals for more than 80 developing countries through international training courses. This technology has spread     4     more and more places in the world so far.

Yuan Longping,     5     cultivated the world’s first high-yield hybrid rice strain not only earned respect from Chinese people but also the global community. His hybrid rice research has been     6     (entire) saving millions of people from hunger. Yuan’s dream was     7     (solve) the global food shortage and promote hybrid rice around the world. China has achieved     8     great wonder, feeding nearly one fifth of the world’s population with less than nine percent of the world’s total land. And China is     9     (will) to contribute to global food security and calls for joint efforts to end global hunger and poverty.

It     10     (believe) that Yuan’s dream will come true one day.

10 . In hot countries the woods are not like our woods. They are great dark forests, where the trees grow so closely together, and are so tall, that if you looked up you could hardly see the sky.

Then there are a great many climbing plants, which twist themselves round and round the trunks and branches of the trees. They are called vegetable cables, because they are so much like ropes. They reach from one tree to another, and almost fill up the spaces between. Troops of monkeys run along the vegetable cables from one tree to another, or swing from the branches by their tails, making a noise all the time as if they are talking to each other. When night comes they roll themselves into a ball, gathered together as close as may be, to keep themselves warm.

Dangers of every kind lie in the forest. The poisonous snake may lie coiled among the bushes, or traces of the wild American tiger may be seen upon the path.

Then there are all sorts of wonderful birds, such as we never see in our country, except in cages. Birds, beasts, and insects live there, for the most part, undisturbed. It is their home; and on every side they are at work, hunting their prey, or escaping from danger. For though man seldom wages war upon them, these wild creatures of the forest are engaged in constant warfare with each other; and the weak are always using some plan to protect themselves from the strong.

There are a great many curious things to be seen in these South American forests.
