Many songs, poems, and books have been written on love’s strong effect on people. The state of being in love has even been compared to being sick or mad. A study by Professor Semir Zeki of University College London has found that love does affect people’s brains by making them feel great.

Zeki studied young men and women who had recently fallen in love. He found that, when they were looking at photos of their loved ones, there was heightened activity in four areas of their brains. These areas deal with emotions, and one of them, in particular, is known to respond to drugs that cause feelings of great joy and excitement.

Interestingly, the study also found a lack of activity in two other areas of the brain when the volunteers looked at their lovers’ photographs. One of these areas is linked to feelings of sadness, while the other is often active in people suffering from depression. It seems love really can be uplifting.

The state of being in love, according to some scientists, may actually be good for your health. Although scientists know that being in love can make a person feel great, the exact influence of love on a person’s health is harder to determine. However, scientists say that people do need love in order to live healthy lives.

According to Dr. Thomas Lewis, people need to be in relationships because that is how we are designed. He says the brain can only maintain(保持) the overall stability of a person’s immune(免疫) system, bodily rhythms, and heart if it receives input(输入) from outside the body in the form of emotional connections with others.

Professor Antonio Damasio has a similar view. He says that love enriches a person’s imagination and creativity, and makes a person’s body work better. He also believes that love can even improve the body’s ability to fight against disease. Damasio’s wise words of advice are “ Choose love and you will live longer.”

1.What is the main idea of this passage ? __________.

A. love can really cause people active

B. love has an effect on songs and books

C. love is linked with emotion

D. love is what we need

2.What does the underlined word “uplifting” mean? It means __________.

A. inspiring　　 B. available　　 C. cold　　 D. mad

3.From the passage we can conclude that__________.

A. People write songs, poems and books to say love is the sweetest thing

B. nobody but Professor Semir Zeki has understood love does affect people’s brains

C. being in love sometimes may make someone act as if he/ she were mad

D. love causes heightened activity in all areas of a person’s brains

4.Which of the following statements is not true?

A. Some scientists have the idea that love does good to people.

B. It is possible for scientists to decide how much influence love can give people.

C. People are born to be in need of getting on touch with each other.

D. A person’s health depends on partly on emotional connections with others.

There are billions of people on this planet, and many of us love to eat meat. Can the demand be filled in a sustainable(可持续的) and affordable way? A bunch of businessmen are not only optimistic but are working to make this happen sooner than you may think.

The environmental effects caused by meat consumption (食用)—waste, animal treatment, health problems and even the greenhouse gas effects that are potentially caused by methane gas produced by cows—have given rise to a number of startups(新兴公司)looking to develop meats in different ways.

For example, San Francisco-based Memphis Meats is developing cell-based meats in its labs without requiring any animals. Israel’s Future Meat Technologies is doing the same by producing fat and muscle cells that are being tested by chefs in Jerusalem. All of these companies use special processes to harvest cells from animals and grow them in a lab.

But don’t worry if you’re not a meat lover. Startups such as Jet Eat, which is also based in Israel, are working on food products grown in labs that are plant-based and replicate (复制) meats using natural elements while still keeping flavor, consistency and the “overall sensory experience”, according to a report on NoCamels. Jet Eat, which was founded in early 2018, aims to 3D-print their lab-grown products by 2020.

As you can imagine, there are plenty of barriers facing the industry. Educating the public is a big one. Another controversial issue is the labeling of the products.　 Recently both the USDA and the Food and Drug Administration(FDA) announced that they will begin jointly controlling the new “cell-based meat” category.

Many of us have concerns about the challenges facing future generations as our global population increases and the earth’s natural resources decreases. The good news is that there are plenty of businessmen around the world—like those producing lab-grown meats—who are working to solve some of these problems and make a little money in the process. Nothing wrong with that.

1.Why do some companies begin to develop new kinds of meats?

A.To analyse the causes of air pollution.

B.To stress the importance of protecting wild animals.

C.To make people less interested in eating meat and more healthy.

D.To meet people’s demand for meat in environmentally friendly ways.

2.What’s special about the lab-grown meats of Jet Eat?

A.They cost less. B.They are plant-based.

C.They are more delicious. D.They are available on the market now.

3.Which of the following is a barrier lab-grown meat industries must deal with?

A.How to let people accept the meat. B.How to give the meat an elegant name.

C.How to produce the meat in large amounts. D.How to reduce the cost of making the meat.

4.What’s the author’s attitude towards lab-grown meats?

A.Supportive. B.Opposing. C.Ambiguous. D.Cautious.

According to a recent survey on money and relationships, 36% of people are keeping a bank account from their partner. While this financial unfaithfulness may appear as distrust in a relationship, in truth it may just be a form of financial protection.

With almost half of all marriages ending in divorce, men and women are realizing they need to be financially savvy, regardless of whether they are in a relationship.

The financial hardship on individuals after a divorce can be extremely difficult, even more so when children are involved. The lack of permanency in relationships, jobs and family life may be the cause of a growing trend to keep a secret bank account hidden from a partner, in other words, an “escape fund”.

Margaret’s story is far from unique. She is a representative of a growing number of women in long-term relationships who are becoming protective of their own earnings. Every month on pay day, she banks hundreds of dollars into a savings account she keeps from her husband. She has been doing this throughout their six-year marriage and has built a nest egg worth an incredible $100,000. Margaret says if her husband found about her secret savings he’d be hurt and would take this as a sign that she wasn’t sure of the marriage. “He’d think it was my escape fund so that financially I could afford to get out of the relationship if it went wrong. I know you should approach marriage as being forever and I hope ours is, but you can never be sure.”

Like many of her fellow secret savers, Margaret was hurt in a former relationship and has since been very guarded about her own money.

Coming clean to your partner about being a secret saver may not be all that bad. Take Colleen for example, who had been saving secretly for a few years before she confessed (坦白) to her partner. “I decided to open a savings account and start building a nest egg of my own. I wanted to prove to myself that I could put money in the bank and leave it there for a rainy day.”

1.The underlined word “savvy” probably means _______.

A. doubtful　　 B. proud　　 C. wise　　 D. simple

2.What can possibly be inferred about Margaret?

A. She is a unique woman.　　 B. She was once divorced.

C. She is going to retire.　　 D. She has many children.

3.The author mentions Colleen’s example to show _______.

A. any couple can avoid marriage conflicts

B. privacy within marriage should be respected

C. everyone can save a fortune with a happy marriage

D. financial confession is not necessarily bad

4.Which of the following is the best title of this passage?

A. Secret Savers　　 B. Love Is What It’s Worth

C. Banking Honesty　　 D. Once Bitten, Twice Shy

高三英语单项填空中等难度题查看答案及解析

While fossil fuels — coal, oil, gas — still produce roughly 85 percent of the world’s energy supply, it’s clearer than ever that the future belongs to renewable sources such as wind and solar. The move to renewables is picking up the development around the world: They now account for more than half of new power sources going in operation.

Some growth stems from a commitment by governments and farsighted businesses to fund cleaner energy sources. But increasingly the story is about the falling prices of renewables, especially wind and solar. The cost of solar panels has dropped by 80 percent and the cost of wind turbines（涡轮机）by close to one-third in the past eight years.

In many parts of the world renewable energy is already an important energy source. In Scotland, for example, wind turbines provide enough electricity to power 95 percent of homes. While the rest of the world takes the lead, especially China and Europe, the United States is also seeing an amazing shift. In March, for the first time, wind and solar power accounted for more than 10 percent of the power generated in the US, reported the US Energy Information Administration.

President Trump has underlined fossil fuels — especially coal — as the path to economic growth. In a recent speech in Iowa, he dismissed wind power as an unreliable energy source. But that message did not play well with many in Iowa, where wind turbines dot the fields and provide 36 percent of the state’s electricity generation — and where tech enterprise like Microsoft are being attracted by the availability of clean energy to power their data centers.

The question “what happens when the wind doesn’t blow or the sun doesn’t shine?” has provided a quick remark for skeptics. But an increase in the storage capacity of batteries is making their ability to keep power flowing around the clock more likely.

The advance is driven in part by vehicle manufacturers, who are placing big bets on battery-powered electric vehicles. Although electric cars are still uncommon on roads now, this massive investment could change the picture rapidly in coming years.

While there’s a long way to go, the trend lines for renewables are zooming. The pace of change in energy sources appears to be speeding up — perhaps just in time to have a meaningful effect in slowing climate change. What Washington does — or doesn’t do — to promote alternative energy may mean less and less at a time of a global shift in thought.

1.According to Paragraph 3, the use of renewable energy in America ______.

A.has proved to be impractical B.is as common as in Europe

C.faces many challenges D.is progressing greatly

2.It can be learned that in Iowa ______.

A.wind is a widely used energy source

B.wind energy has replaced fossil fuels

C.there is a shortage of clean energy supply

D.tech enterprises are investing in clean energy

3.Which of the following is true about clean energy according to Paragraphs 5&6?

A.Its application has increased battery storage.

B.Its continuous supply is becoming a reality.

C.It is commonly used in car manufacturing.

D.Its sustainable exploitation will remain difficult.

4.It can be inferred from the last paragraph that renewable energy ______.

A.will bring the US closer to other countries

B.will accelerate global environmental change

C.is not really encouraged by the US government

D.is not competitive enough with regard to its cost

The human body is a living machine, and, like all machines, it needs "fuel" （燃料） to supply it with energy．This is provided by the food we eat．But how much do we need to stay healthy?

The energy value of food is usually measured in calories．A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃．The number of calories people need per day is different．Also, the number of calories you use at any one moment normally depends on the activity you are in．For example, you need more calories for standing than for sitting, more for running than for walking, and so on．

The energy in food is in the form of three kinds of chemical materials-carbohydrate（碳水化合物）, protein（蛋白质）and fat．Carbohydrate provides 3．8 Cal/gm, protein 4．0 Cal/gm, and fat 8．8 Cal/gm．Each food contains different amount of these materials, as the round pictures show．

1．The amount of calories supplied by equal amounts of milk, rice, and peanuts is the largest in the case of ________．

A．milk             B．rice               C．peanuts        D．rice or peanuts

2．Choose one statement from among A-D that agrees with the passage and the pictures above．

A．You need more calories for swimming than for mountain climbing．

B．Food contains energy in the form of carbohydrates, proteins and fuel．

C．Different people need different amounts of energy depending on their age, sex and the activities they are in．

D．3 grams of milk provides 16．6 calories because carbohydrate provides 3．8 Cal/gm, protein 4．0 Cal/gm and fat 8．8 Cal/gm．

3．This article mainly tells us ________．

A．all the energy is in food           B．the human body needs energy

C．the number of calories depends on your activity
