【题目】 5G has the potential to disrupt a huge number of industries, including one of the world’s oldest: Farming. Next-generation 5G networks can be 100 times faster than 4G, making communication between devices and servers much quicker. 5G can also carry much more data than other networks. That makes the technology ideal for transmitting information from remote sensors and drones, key tools that are being tested by farmers. 5G is also helping to automate farming processes.

UK initiative 5G RuralFirst launched a smartphone app in March called Me+Moo, which lets farmers track a “connected” cow and receive daily updates on the animal’s health and behavior. The system, which is being tested on cows at the Agri-Epi Center in Somerset, England, is funded in part by UK government and supported by the tech company Cisco (CSCO). The cows wear 5G-connected collars that send data to the app on everything from what they’re eating to how they’re sleeping. Farmers can see the information instantly. “This provides peace of mind that the cows are happy, healthy and behaving normally, as well as early warning if they are getting sick, are pregnant or need to be checked,” said project manager Duncan Forbes.

Yet to make a difference, 5G will first need to be installed in rural areas. The UN Food and Agriculture Organization (FAO) predicts that in order to provide for the world’s rapidly rising population, the planet will need to grow 70% more food in 2050 than it did in 2009. “To respond to those demands, farmers will need new technologies to produce more from less land, with fewer hands,” reads one report from the organization.

In 2017, another 5G RuralFirst project became the first in the world to successfully plant, tend and harvest a crop without a single human stepping foot in the field. Autonomous Automatic tractors sowed the seeds, drones with sensors monitored the crops, and smaller machines took samples from fields to assess what fertilizers and pesticides to apply.

1Why can 5G help the farming?

A.Because it can carry more information.

B.Because it can be equipped with sensors.

C.Because it can disrupt a lot of industries.

D.Because it can be installed in rural areas.

2What did farmers do firstly if they wanted to use Me+Moo?

A.They founded a tech company.

B.They let the cows wear 5G-connected collars.

C.They kept cows behaving normally.

D.They made sure the cows were checked often.

3According to FAO, how will the world solve the food problem?

A.People should control the rising population.

B.People should find more and more land.

C.People should turn to the new technology.

D.People should learn to get more money.

4How did RuralFirst decide what kind of fertilizer to apply?

A.It analyzed the soil.

B.It dug earth with tractors.

C.It employed experts.

D.It hired drones with sensors.

【题目】 Would you leave a six-figure job to feed the homeless? This 27-year-old did. Robert Lee’s idea is seemingly simple: Get restaurants to make better use of their leftovers (剩饭菜).

When in primary school, Robert Lee would stare in disbelief at his classmates throwing away half-eaten sandwiches after lunch. His immigrant parents had taught him and his older brother not to waste food. “They said it was a bad habit,” says Robert, 27.

While studying finance and accounting at New York University, Robert remembered this lesson and joined Two Birds One Stone, a food-rescue club on campus that delivered, five days a week, uneaten pasta, vegetables, and other leftovers from the dining hall to nearby homeless shelters. In July 2013, with the $1,000 prize won in the a college entrepreneurship (创业) contest, Robert and fellow club member Louisa Chen founded Rescuing Leftover Cuisine (RLC). In just the first few weeks, Robert’s team delivered a donation of food to feed 20 people in line at a New York City homeless shelter that had run out of food.

As an analyst at J.P. Morgan, Robert devoted his spare time to creating a network of New York City restaurants that agreed to donate food, and he enlisted (招募) volunteers to make food deliveries to homeless shelters. Two years after being founded, RLC had already distributed more than 250,000 pounds of food.

Only a year into his finance job, Robert gave up his six-figure salary to focus on RLC. “I compared one hour of impact at J.P. Morgan to one hour at RLC, and the difference was just tremendous,” he says. The organization now reaches 16 cities around the country.

“One shelter told us that our donations allow them to provide entire dinners for more than 300 people, three nights a week,” Robert says. “Things like that make me glad I quit my job.”

1What did Lee do to help the homeless?

A.He worked with with other countries.

B.He built up a network of supermarkets.

C.He employed volunteers to deliver goods.

D.He co-founded Rescuing Leftover Cuisine.

2What does the underlined word “tremendous” in Paragraph 5 mean?

A.Slight.B.Huge.

C.Basic.D.Delicate.

3What can we learn from Lee’s words in the last two paragraphs?

A.Being a volunteer is of great benefit.

B.People should follow in his footsteps.

C.Everyone can make their contributions,

D.It’s worthwhile sacrificing his well-paid job.

4Which of the following can best describe Lee?

A.Devoted.B.Hardworking.

C.Patient.D.Optimistic.

【题目】 It's tough to see or hear of a friend in crisis. One idea to keep in mind is that it is healthy for the distressed person to feel what he or she feels in the moment. When a person in crisis feels understood, he or she feels less alone and connected to the person who understands.

A person who experiences empathy(同理心)from a friend who can “go there”for a few minutes in order to authentically understand while still maintaining a strong and supportive attitude may be relieving and healing. While a friend is telling you about the circumstance, the first and most important step is to listen for feelings, not ways to solve the problem.

For example, a friend is terribly upset because her husband is threatening to leave her. After fully honoring the feelings, it is important to ask the friend what would help. Maybe it is a good cry and some ice cream. Perhaps it's a glass of wine and a walk. Everyone has different ways of dealing. Be respectful and ask the friend what she needs or wants, not what you prescribe.

Take a second example, say a close friend is being misrepresented by other friends. The friends are gossiping about her. During a conversation with her, listen for feelings. Honor her hurt and shock. The same equation is useful with a partner.

Helping a friend or partner in crisis not only helps the person, but creates closeness and trust in the relationship, making opening up in the probable future. In addition, the person who is empathizing feels positive because he or she was able to help. When a person is truly able to comfort and reassure a loved one, he or she feels vital and useful, strengthening the relationship.

1What should we do first when we know a friend is in crisis

A.Keep away from him/her.

B.Buy him/her a glass of wine.

C.Understand how he/she feels.

D.Show him/her ways to solve the problem.

2What does the underlined word “it” in paragraph 3 refer to

A.A way to solve the crisis.B.A way to relieve a bad mood.

C.A way to listen for feelings.D.A way to honor the feelings.

3How does the author prove his/her idea

A.By listing data.B.By quoting sayings.

C.By giving examples.D.By conducting surveys.

4What does the text mainly talk about

A.How to keep a loved one.B.How to make new friends.

C.How to work with your partner.D.How to help a friend in trouble.

【题目】 Vitamin B could help lessen the effects of the most dangerous type of air pollutionaccording to a new study published recently. In the first study of its kinda team of international researchers looked at the damage caused by one of the pollutants that has the most severe impact on health: PM2.5.

Particulate matteror PMis a type of air pollutant consisting of small particles of different sizes. PM2.5 has a diameter of fewer than 2.5 micrometersabout 30 times smaller than a human hair. These particles are so small that they can go into our respiratory system (呼吸系统), resulting in lung and systemic inflammation (炎症) and stress.

The team found that something as simple as a daily vitamin B supplement could potentially reduce the impact of the tiny particles on the human bodyalthough they stressed that the research was in its early stages and the sample size was small.

For this study10 volunteers were initially exposed to clean air and given a placebo (安慰剂) to check their responses. The group then took another placebo for four weeks before being exposed to heavily polluted air from downtown Torontowhere an estimated 1000 cars pass every hour. The bad air was delivered to the volunteers through an “oxygentype” face mask. The experiment was then repeatedwith each volunteer taking a vitamin B supplement daily made up of 2.5 mg of folic acid50 mg of vitamin B6and 1 mg of vitamin B12. B6 can be found in liverchicken and nutsand B12 in fishmeateggsmilk and some cereals.

The researchers found that four weeks of vitamin B supplements reduced the damage of PM2.5 exposure by 28%76%. The results highlight how prevention at an individual level could be used to fight the harmful effects of PM2.5.

1Why is PM2.5 harmful to our health?

A.It pollutes and poisons the air.B.It is too much to be got rid of.

C.It carries viruses and diseases.D.It is easily breathed in and damages our body.

2What can we infer from Paragraph 3?

A.The process of the research was not scientific.

B.This kind of research has been done many times.

C.Further studies are needed to confirm their findings.

D.Vitamin B is hard to obtain in people’s daily life.

3What is the text mainly about?

A.International researchers have a new finding.

B.Vitamin B could reduce the damage of PM2.5.

C.Particulate matter does great harm to our health.

D.Emission control and regulation are badly needed.

4The new study was probably published ________.

A.in a science journalB.on a government website

C.in a fashion magazineD.in a medical textbook
