Companion planting is the idea that some kinds of plants can help each other grow. Plants that are compatible（兼容的，能共处的） together generally have similar needs in terms of nutrients，soil and moisture levels.

Advice about which plants are compatible is sometimes based more on tradition than proof. But experts say there is evidence to support certain combinations. These can improve harvests，reduce disease and help with pest control by attracting helpful insects.

For example，some kinds of soil bacteria take nitrogen from the air and make it into a form that plants can use. The plants hold the nitrogen in their roots. Legumes(豆科植物)are especially good at this nitrogen(氮)fixing. Then any crops that share the same space with the legumes can get the nitrogen when the roots are broken down.

Beans and potatoes can also share territory well because their roots reach different levels in the soil. Deep-rooted vegetables get nutrients and moisture from lower down in the soil，so they do not complete with plants with shallower roots.

But some plants placed together may harm each other's development. For example，tomatoes do not like wet soil but watercress does，so you would probably want to keep them separated.

Some kinds of produce should be kept apart even after being harvested. This is because of ethylene gas(乙烯气体)．Ethylene is a plant hormone(激素)that can cause some foods to ripen too quickly. Apples release ethylene gas. Apricots，melons and tomatoes also release a lot of ethylene. Some vegetables are easily affected by ethylene，including asparagus，broccoli，cabbage and cucumbers.

This risk of ripening too soon is why markets often separate high ethylene-producing foods from those that are sensitive to the gas. But if you put an apple in a bag with a green banana，the ethylene from the apple will make the banana ready to eat sooner.

What about peaches，plums and nectarines? These kinds of fruit do not need any help from an apple—they release enough ethylene to ripen themselves. But that does not mean there is no way to get the job done faster.

Growers suggest placing the fruit in a fruit bowl or in a paper bag with the top folded over. Keep the fruit at room temperature，out of direct sunlight. Once the fruit is soft enough，either use it or put it in the refrigerator to keep it from getting too ripe.

1.Companion planting refers to the idea that 　　　　　 ．

A. some crops can grow together to benefit each other

B. some crops have the similar needs of nutrients，soil and water level

C. some plants can damage each other if grown together

D. a good farming method to prevent natural disasters

Vegetable gardening is the relaxing art and science of turning a love for growing plants into a worthwhile activity.

Vegetable gardeners agree that many home-grown vegetables picked at their best are superior to those vegetables purchased from markets. From spring through late fall, a well-planned and well-kept garden can prove a supply of fresh vegetables, thus increasing the nutrition of the family diet. Freezers make it possible to keep some of the vegetables to be enjoyed at a later date. Other vegetables can be stored for a few months in a cool area.

Having vegetables in the backyard makes home gardening appealing(吸收人的) for many people. In addition, vegetable gardening provides exercise and fun for both urban and suburban families.

Although the money spent for a garden may be little, one cannot escape the fact that gardening requires hard work and time. Many of the gardening tasks must be performed at times that are most inconvenient. Not doing jobs that should be done on a regular basis may result in failure and a negative feeling toward gardening.

One should not plant a garden that is too large for him to care for. A small, well-kept garden is more enjoyable and profitable than a large neglected one. Vegetables do well in full sunlight and need at least five or six hours of sun during the middle of the day. Too much shading results in poor plants and few vegetables. If possible, the garden should be near the house so the gardener can work in it at odd moments.

Soils for vegetables should be easily broken up and porous(能渗透的) for quick water drainage and good aeration(透气). A deep, fine, sandy good quality soil is best.

Usually the hoe owner has little choice in the soil type he can choose. Fortunately, many vegetables can be grown on poor soils if the soils are properly prepared.

1.Home-grown vegetables ___________.

2.Vegetables gardening is appealing for many people because ___________.

3.The author suggests that an ideal vegetable garden ___________.

4.Which of the following would be the best title for this passage?

高二英语阅读理解简单题查看答案及解析

The number of buses, taxis and other vehicles on Kenya’s roads is growing every day. Now, the country’s first electric-powered motorbikes are coming onto the market. The bike is designed to cut down on pollution and aimed at low-income communities. Most motorbikes used in Kenya depend on gasoline, but not this new motorbike.

Three university students developed the new ecotran bike. It catches the sun’s energy, stores it in batteries and uses it to charge (充电) the electric motor. Robert Achoge is one of the student inventors. “Our hope is that by the fifth year, we will be able to cover the whole of Kenya with the electric motorcycle so as to protect the environment and provide affordable transport.”

The students have set up a charging station for the motorbikes in Nairobi. The small battery can run for 70 kilometers when fully charged. Once the power is used up, the motorbike has to return to the station while another charged battery is connected to the bike. The U.S. African Development Foundation (ADF) is helping set up two solar-powered charging stations in the port of Kisumu.

Each ecotran bike costs about $700. One taxi operator says the new motorbike costs less to operate than that running on traditional gasoline. “When it comes to buying gasoline, there’s no need. It’s basically good for various things. As long as you won’t take quite a heavy load (装载), you can go with it anywhere. Otherwise, it may break down halfway. But now people still have a preference to the gas-powered bikes.”

A Nairobi businessman Kennedy Kusimba is selling the ecotran bikes. He hopes they will become popular. “We also know they are more reliable compared to the gas-powered bikes. They are more efficient (效率高的) and they will last longer.”

1.What has happened to the vehicles in Kenya?

A. Motorbikes are not allowed on the road.

B. A new kind of motorbike is hitting the road.

C. There are fewer buses and taxis in the street.

D. Traditional motorbikes don’t need gasoline any more.

2.What do we know about the ecotran bike?

A. It was developed by the ADF.

B. It can charge itself while running.

C. Its energy comes from the sunlight.

D. It does more harm to the environment.

3.What do people think of the ecotran bike?

A. It’s better not to use it to carry too much.

B. It is a good choice for the long-distance journey.

C. It will take the place of gas-powered bikes soon.

D. It is much more expensive than a traditional motorbike.

4.Where does the text probably come from?

A. A research plan.　　 B. An advertisement.

C. A business report.　　 D. A science magazine.

Attitude is an internal state that influences the choices of personal action made by the individual. Some researchers consider that attitudes come from differences between beliefs and ideas; others believe that attitudes come from emotional states. Here, we focus on the effects of attitudes upon behavior, that is, upon the choices of action made by the individual.

The kinds of actions taken by human beings are obviously influenced greatly by attitudes. Whether one listens to classical music or rock, whether one obeys the speed limit while driving, whether one encourages one’s husband or wife to express his or her own ideas—all are influenced by attitudes. These internal states are acquired throughout life from situations one is faced with in the home, in the streets, and in the school.

Of course, the course of action chosen by an individual in any situation will be largely determined by the particulars of that situation. An individual who has a strong attitude of obeying laws may drive too fast when he is in a hurry and no police cars in sight. A child who has a strong attitude of honesty may steal a penny when she thinks no one will notice. But the internal state which remains unchanged over a period of time, and which makes the individual behave regularly in a variety of situations, is what is meant by an attitude.

Attitudes are learned in a variety of ways. They can result from single incidents, as when an attitude toward snakes is acquired by an experience in childhood at the sudden movement of a snake. They can result from the individual’s experiences of success and pleasure, as when someone acquires a positive attitude toward doing crossword puzzles by being able to complete some of them. And frequently, they are learned by copying other people’s behavior, as when a child learns how to behave toward foreigners by observing the actions of his parents. Regardless of these differences, there is something in common in the learning and modification（修正）of attitudes.

1. According to the passage, attitudes _________.

2.The author uses the examples in Paragraph 3 to show _________.

3.Which of the following is TRUE about the learning of attitudes?

4.What would be the best title for the passage?

高二英语阅读理解中等难度题查看答案及解析

As we grow up, we gradually develop a set of our own values or beliefs. These are influenced by society, our family, the education we receive and so on. Once this value system is set up, it’s not easy to change later in life. Financial experts say that everyone also has his own belief of how to manage his money. According to our different values, experts put us in three catagories---the ant, the cricket(蟋蟀) and the snail.

★ The ant — work first

Just like ants who work heart and soul in summer in order to store food for winter, these people don't care about enjoying the moment. They work very hard and save money they earn so that they can enjoy life when they get old and retire. The ant loves to save, but they could make more out of their money if they were willing to invest in some funds and stocks with low risk.

★ The cricket — fun first

The cricket wants to enjoy everything now and doesn't think too much about the future. They even borrow money when they really want something. Many young people now belong to this group. These people have little savings. When they get old, they might have problems. They should learn to save and buy insurance.

★ The snail — life under pressure

The snail refers to people who make life difficult for themselves. They take big long-term loans(贷款) from the bank in order to buy things such as luxury houses. They are happy to take big loans even though they are not sure they can afford them. This can cause problems in the future. They should plan more carefully.

1.  One’s values may________.

A. be his ways of managing money

B. be his beliefs about society

C. be connected with his education

D. influence his behavior

2.  Mr. Smith always enjoys spending a weekend with his friends, fishing, hunting and playing cards. Besides, he spends money in a very luxurious way. So_______.

A. Mr. Smith belongs to the ant type

B. Mr. Smith belongs to the cricket type

C. Mr. Smith belongs to the snail type

D. it’s hard to tell which kind of person Mr. Smith is

3. The writer of the passage intends _______.

A. to introduce to us the three types of people with different life style

B. to show us his special attitude to the different people

C. to tell us life is full of joy and happiness all the time

D. to warn us how to live a better life in a new way

4. According to the passage, the most suitable title would be _______.

A. Nature of Spending

B. What Comes First

C. How to Understand Your Belief

D. Work and Fun

Recent findings have shown that our appetite and food intake are influenced by a large number of factors besides our biological need for energy, including our eating environment and our perception (感知) of the food in front of us. A new study suggested that our short-term memory may also play a role in appetite. Several hours after a meal, people's hunger levels were predicted not by how much they'd eaten but rather by how much food they’d seen in front of them — in other words, how much they remembered eating.

This difference suggests the memory of our previous meal may have a bigger influence on our appetite than the actual size of the meal, says Jeffrey M. Brunstrom, a professor of experimental psychology at the University of Bristol.

''Hunger isn't controlled merely by the physical characteristics of a recent meal. We have identified an independent role for memory for that meal, '' Brunstrom says. ''This shows that the relationship between hunger and food intake is more complex than we thought. ''

These findings echo earlier research that suggests our perceptions of food can sometimes trick our body's response to the food itself. In a 2016 study, for instance, people who drank the same 380-calorie milkshake on two separate occasions produced different levels of hunger-related hormones (荷尔蒙), depending on whether the shake's label said it contained 620 or 140 calories. Moreover, the participants reported feeling more full when they thought they'd consumed a higher-calorie shake.

1.What affects our appetite according to the new study?

A.How much we remember eating.

B.What time we eat our last meal.

C.How much we eat our last meal.

D.What ingredients the food contains.

2.The underlined word ''echo'' in the last paragraph means ________ in Chinese.

A.暗示 B.反映

C.印证 D.改善

3.What is the main idea of the text?

A.Good eating habits contribute to our health.

B.Eating speed often affects our food digestion.

C.Psychological factors influence our hunger levels.

D.Our biological need for energy determines our food intake.
