Remittance (汇款) increase living standards in the country of origin. Remittances m a large share of the GDP of many developing countries. A study on remittances to Mexico found that remittances lead to a considerable increase in the availability of public services in Mexico, surpassing government spending in some localities.

Research finds that emigration and low migration barriers have net positive effects on human capital formation in the sending countries. This means that there is a “brain gain” instead of a" brain drain to emigration.

One study finds that sending Countries benefit indirectly in the long run from the emigration of skilled workers because those skilled workers are able to innovate more in developed countries, which the sending countries are able to benefit as a positive externality. Greater emigration of skilled workers consequently leads to greater economic growth and welfare improvements in the long run.

Research also suggests that emigration, remittances and return migration can have a positive impact on political institutions and democratization in the country of origin. Research also shows that remittances can lower the risk of civil war in the country of origin. Return migration from countries with liberal gender norms has been associated with the transfer of liberal gender norms to the home country.

Research suggests that emigration causes an increase in the wages of those who remain in the country of origin. A 2014 survey of the existing literature on migration finds that a 10 percent emigrant supply shock would increase wages in the sending country by 2 % - 5.5 %. A study of emigration from Poland shows that it led to a slight increase in wages for high-and medium-skilled workers for remaining Poles. A 2013 study finds that emigration from Eastern Europe after the 2004 EU enlargement increased the wages of remaining young workers in the country of origin by 6%, while it had no effect on the wages of old workers. The wages of Lithuanian men increased as a result of post-EU enlargement emigration. Return migration is associated with greater household firm revenues(收入).

Some research shows that the remittance effect is not strong enough to make the remaining natives in countries with high emigration flows better off.

It has been argued that high-skill emigration causes labor shortages in the country of origin. This remains unsupported in the academic literature though. According to economist Michael Clemens, it has not been shown that restrictions on high-skill emigration reduce shortages in the countries of origin.

1. This passage mainly tells us that ______
A.people's living standards in the receiving countries have been greatly improved
B.emigration has both advantages and disadvantages to the sending countries
C.the reasons behind economic growth in the sending countries
D.the effect of migration on the sending countries
2. From the first three paragraphs, we know that ______
A.the emigration of skilled workers brings economic growth to developed countries
B.emigration means a kind of “brain gain” rather than "brain drain"
C.the government in Mexico should spend more on public services
D.highly qualified workers are bound to return to their home country
3. The examples in Paragraph 5 show that ______
A.return migration makes the natives better off
B.a wage increase is associated with economic growth
C.enlargement brings welfare to all Europeans
D.emigration leads to a salary increase for remaining natives
4. According to the passage, what can we know about the country of origin?
A.The negative effects of high-skill emigration have shown up.
B.Remittances have a good effect on maintaining social stability,
C.High migration barriers can reduce shortages of skilled workers.

文章大意:本文是一篇说明文。文章主要介绍了电话文化正在消失,并分析了电话文化消失背后的原因以及影响。

【推荐1】Everyone has a phone in their pocket nowadays, but how often do we really use them for their original purpose—to make a call? Telephone culture is disappearing. What brought us to this moment, and what are its effects?

“No one picks up the phone anymore,” wrote Alex C. Madrigal on The Atlantic. “The reflex (习惯性动作) of answering—built so deeply into people who grew up in 20th-centurytelephonic culture—is gone.”

The shift is of course due in large part to more communication options: Texting with photos, videos, emojis, reaction gifs, links and even voice messages can be a more attractive option.

Texting is light and fun, not nearly as demanding of your attention as a phone call. It can also be done with multiple people at the same time. Social media, email and video calls have also eaten away at traditional phone calls.

In recent years, another reason has caused people to ignore phone calls completely: robocalls. Robocalls are automated messages from organizations verifying (核实) your phone number or telemarketers trying to sell something. Americans received 22.8 billion robocalls halfway through 2020, equaling an annual rate of 45.6 billion, slightly below 2018 numbers, according to You-Mail, a robocall protection service and blocking app.

As telephone culture disappears, what is the loss of a singular family phone doing to the family unit? Early landline phones unified family members, whereas mobile phones isolate (使隔绝) them.

“The shared family phone served as an anchor (给以安全感的物品) for home,” said Luke Fernandez, a Weber State University computer-science professor and co-author of Bored, Lonely, Angry, Stupid: Feelings About Technology, From the Telegraph to Twitter. “With smartphones, we have gained mobility and privacy. But the value of the home has been diminished, as has its capacity to guide and monitor family behavior and perhaps bind families more closely together,” Fernandez said.

Of course, as technology progresses, lives always change for better or for worse. With the loss of telephone culture, families will need to find other ways to unite.

1. What has caused the traditional telephone to lose its appeal according to the text?
A.People’s addiction to social media.
B.People’s preference for robocalls.
C.People’s growing need for privacy.
D.People’s wide range of communication choices.
2. What does the underlined word “diminished” in the second-to-last paragraph probably mean?
A.Reduced.B.Strengthened.
C.Instructed.D.Inherited.
3. What’s the advantage of a family phone?
A.Gain mobility.B.Receive robocalls.
C.Send messages.D.Tie family members.
4. What does the article mainly talk about?
A.The past and future of telephones.
B.The development of communication tools.
C.The downfall of traditional telephone culture.
D.The relation between phone use and family bonds.

【推荐2】The U.S. is still out in front of global competitors when it comes to innovation(革新), but American universities-where new ideas often spread - have reason to look over their shoulders.

That's especially true for technologies like 5G phone networks and artificial intelligence. In President Donald Trump's opinion, they're exactly the fields where the U.S. has to lead-and also the ones where Asia, especially China, is catching up. Universities from China get more patents than their U.S. peers in wireless communications, according to a research firm named GreyB Services. In Al, 17 of the top 20 universities and public research organizations are in China, with the Chinese Academy of Sciences topping the list, says the World Intellectual Property Organization in Geneva.

There's a special place for universities in the development of science. Universities educate future scientists and can be incubators(孵化器) for pie-in-the-sky ideas - some of which turn out to be game-changers. The list ranges from Google's search engine to DNA technology that's behind a whole industry of gene-manipulating(基因编辑) treatments.

However, government aids to universities haven't been growing for more than a decade, meaning they've declined in real terms and as a share of the economy, leading to the cost increase for universities and meanwhile somehow discouraging the teaching staff from putting all their hearts into their scientific research.

“If you look at the federal dollars, they've not really changed considerably,” says Stephen Susalka, head of AUTM, a technology transfer association whose members include 800 universities. “Other countries are catching up. We can't be satisfied with what we have achieved?”

1. What does the underlined phrase “look over their shoulders” in Paragraph 1 mean?
A.Watch out.B.Take off.
C.Stand up.D.Hide away.
2. The author mentions 5G phone networks to show .
A.Chinese universities have obtained the most patents
B.Chinese universities get aids from the government
C.wireless communications have changed dramatically
D.U.S. may lose their lead in some high-tech fields
3. What is the main idea of Paragraph 3?
A.Pie-in-the-sky ideas can be revolutionary.
B.Universities can produce game programmers.
C.Gene-manipulation helps to develop DNA technology.
D.Universities play an important role in science development.
4. What's Stephen's attitude to the future development of US universities?
A.Worried.B.Disapproving.
C.Positive.D.Unconcerned.

文章大意:本文是说明文。文章讲述了由于新冠疫情而导致的全球性的饥饿危机。

【推荐3】’Instead of corona virus, the hunger will kill us.’ A global food crisis appears.

In the largest slum(贫民窟) in Kenya’s capital, people desperate to eat cause chaos during a recent giveaway of flour and cooking oil, leaving scores injured and two people dead.

In India, thousands of workers are lining up twice a day for bread and fried vegetables to keep hunger away.

The corona virus pandemic has brought hunger to millions of people around the world. An estimated 265 million people could be pushed to the edge of starvation by year’s end. “We’ve never seen anything like this before,” said Arif Husain, chief economist at the World Food Program, a U.N. agency. “It wasn’t a pretty picture to begin with, and this makes it probably worse.”

The world has experienced severe hunger crises before, but those were regional and caused by one factor or another — extreme weather, economic downturns, wars or political instability. This hunger crisis, experts say, is global and caused by a variety of factors linked to the corona virus pandemic and the following interruption of the economic order.

There is no shortage of food globally, or mass starvation from the pandemic — yet. But problems in planting, harvesting and transporting food will leave poor countries exposed in the coming months, especially those dependent on imports, said Johan Swinnen, director general of the International Food Policy Research Institute in Washington.

To lessen the impact of this crisis, some governments are fixing prices on food items, delivering free food and carrying out plans to send money transfers to the poorest households. Yet, communities across the world are also taking matters into their own hands. Some are raising money through crowdfunding platforms, while others have begun programs to purchase meals for needy families.

1. What can we know from the scenes of people getting food in Kenya and India?
A.Food shortage is becoming increasingly severe.
B.People in Kenya and India are rude and mean.
C.Food shortage causes people to go on strike.
D.People are afraid of being infected by corona virus.
2. What is Arif Husain’s attitude to the starvation caused recently?
A.Hopeful.B.Doubtful.C.Uncaring.D.Pessimistic.
3. Why is this hunger crisis different from the previous hunger crises?
A.It is global and caused by various factors.
B.It has caused mass starvation regionally.
C.It is caused by natural disasters.
D.It is caused by the economic disorder.
4. Which of the following measures is taken by the governments for this hunger crisis?
A.Raising money.B.Buying meals.
C.Giving out free food.D.Setting prices on goods.
