Over the past few months, COVID-19 has caused great uncertainty around the world affecting people's lives in all aspects.Education is also greatly affected. With students all turning to online instruction, live-streamed classes have become popular among schools and universities.　 1.

In China, the use of e-learning is unusual not only in size but also in depth. 2. For another, it proves how modern technology changes the way students are educated and encourages further research and development of educational technology to introduce virtual communities between students and teachers.

In fact,online instruction as an alternative teaching mode has been expanding rapidly in recent years.Many Chinese start-ups focus on AI applications in online courses,and various online educational platforms are set up.3. The online education platform MOOC,where a wide variety of courses is available,has attracted the world's top universities to upload and share resources with students around the world.

Compared with formal instruction,online courses save abundant costs and create a flexible teaching mode(模式）－homeschooling,especially during a crisis. 4.For example,rural students with no access to the Internet and television might be left behind in this new mode.When e-learning becomes the only solution for delivering knowledge,the existing divide could be widened,further deepening education inequality.Also,the quality of teaching becomes heavily dependent on uncertain factors,such as a stable connection to the Internet and technical skills.

5.Yet,the pandemic(流行病）has undoubtedly affected the teaching style in a sweeping manner and given educators around the world plenty of time and space to think about the alternative educational modes.

A.However,online teaching has its own disadvantages.

B.The traditional face-to-face teaching style has been challenged.

C.Chinese colleges and universities started the spring term online.

D.Moreover,online education is fairly acceptable to college education.

E.Online teaching provides a chance to reconsider the current education system.

F.For one thing,the impressive practice sets a good example to other countries.

G.So,it's early to predict how the future of the education system will look like.

Over the past few months huge groups of locusts(蝗虫), one of which occupied an area more than three times the size of New York City, have eaten up crops across the Home of Africa and the Middle East, leaving an estimated 20 million people at risk of famine(饥荒). The first generation's eggs are starting to hatch, and now even bigger swarms(虫群) are forming threatening. Countries from the Democratic Republic of Congo to Yemen, Iran, Pakistan and India, “representing a threat to food security and livelihoods,” says the U.N.'s Food and Agriculture Organization(FAO).

Desert locusts' populations explode when weather conditions are right. That explosion can create huge swarms that can travel great distance-more than 90 miles in a day-in search of food. Warm weather and unusually heavy rains in the Horn of Africa at the end of 2019 provided the moist(湿润的) soil necessary for hatching eggs. From there, the insects spread rapidly, resulting in one of the worst outbreaks the region has seen in more than 70 years.

A typical swarm numbering 4 billion to 8 billion locusts, can consume in one day the same　 amount of food as 35 million people. Some swarms have been so thick in parts of Kenya that they have prevented planes from taking off. Governments have used widespread aerial spraying of pesticides when available; in poorer regions, where aircraft are unavailable, soldiers battle the swarms with handheld spray pump.

The FAO has appealed for $138 million to support affected communities, If the locusts are not stopped before the next generation hatches, the impact could be terrible: the FAO guesses that an additional 25 million people across the region could lose their crops. Scientists in Kenya hope a new computer-assisted tracking program that combines satellite data with weather-mapping software will help predict the swarms next destination, buying-regional authorities enough time to prepare a response. Buy coronavirus- related travel restriction have delayed relief efforts as well as response mechanisms. The locusts have no such travel limitations.

1.The author uses many statistics in the passage to show_____

A.the disastrous consequence of the outbreaks of locusts

B.the serious conditions facing the New York City

C.the speed of swarms of locusts travelling

D.the exact number of crops consumed by locusts

2.What is Paragraph 2 mainly about?

A.The great distances locusts can travel.

B.The explosion of locusts' population.

C.The perfect conditions for hatching their eggs.

D.The result of the unusual outbreaks of locusts.

3.What does the last paragraph imply?

A.The travel restrictions may probably worsen the urgent situation.

B.It is unlikely to predict the swarms' next destination now.

C.A lot of money has been raised after the FAO's appeal

D.It's not difficult for humans to win the battle against the locust
