An airline passenger ensured a 20-year-old man was reunited with his lost wallet-along with a little extra something to make up for their time apart.
Hunter Shamatt first lost his wallet while he was on a Frontier Airlines flight from Omaha to attend his sister's wedding in Las Vegas earlier this month. On realizing his wallet was lost, he contacted the airline to see if anyone had turned it in—but to no avail. Since the wallet contained his ID, a signed paycheck, his debit card and $60 in cash, he “feared the worst”.
Shortly after the flight, however, Hunter was shocked to receive a package in the mail from an unknown sender. Inside was his wallet-along with an additional $40 in cash.
“Found this on a Frontier flight from Omaha to Denver-row 12, seat F stuck between the seat and wall,” read a letter in the package. “Thought you might want it hack. All the best. PS: I rounded your cash up to an even $100 so you could celebrate getting your wallet hack. Have fun!”
Hunter's mother, Jeannie, posted a photo of the letter to social media in hopes that they would be able to track down the sender and thank them for their kindness. All they had to go on was that the letter was sent from Applied Underwriters in Omaha and the sender's initials were signed: "T.B".
The Good Man was later identified as Todd Brown, a father-of-five who was delighted at the chance to "have a little fun" with helping out a hard-working stranger. Brown says that he often tries to do good deeds without any recognition, thus why he didn't sign his full name on the letter, but Jeannie later insisted on praising the Nebraska native on social media.
“I try to teach my children to do the right things in life, help people when you can despite the outcome,” she wrote on Facebook. “This story is more about restoring faith in people than anything”.
1.What does the underlined word "to no avail" in paragraph 2 mean?
A.Under discussion. B.In vain. C.Beyond belief. D.At a loss.
2.Why did Jeannie upload a picture of the letter to social media?
A.To throw light on the truth.
B.To draw attention to Hunter's lost wallet.
C.To find out the sender to express gratefulness.
D.To sing high praise for the sender's generosity.
3.Which of the following best describes Brown?
A.Innocent. B.Warm-hearted. C.Romantic. D.Easy-going.
4.What's the best title for the text?
A.Hunter Shamatt-a Lucky Man B.Young Passenger Reunites with Sister
C.Helping Needy People Is a Great Virtue D.Stranger Returns Lost Wallet with More Cash Inside

The outbreak of locusts, an insect that mainly lives in Africa and Asia, is the worst experienced by Kenya in 70 years. The crowds are some three times the size of New York City, eating their way through thousands of acres of crops and animal grassland and destroying livelihoods in the process.
“These hungry things are alarming,” says Keith Cressman, the UN Food and Agriculture Organization's senior locust forecasting officer. "A crowd the size of Manhattan can, in a single day, eat the same amount of food as everyone in New York and California combined."
Desert locusts are infamous for their ability to breed(繁育)rapidly in large numbers every three months. And with some help from the wind, they can travel as much as 80 miles a day. Most years, the insects stay in African deserts. However, under the right environmental conditions, they can multiply quickly, spread as much as 400 times every six months and cause extensive destruction if left unchecked.
“The insect has the ability to take advantage of good conditions.” Cressman says.
The "good conditions" the scientist is referring to began in mid-2018 when a rainstorm from the Indian Ocean struck a remote area of the Arabian Peninsula known as the "Empty Quarter". Normally, it would dry out within a short period, killing most of the locust population, which depends on green plants for food. However, in late 2018, a second rainstorm struck the same region. The huge sandy area got wet, which is exactly what desert locusts need to lay their eggs and breed. The extra food supply caused the population to explode for the second time in six months.
Luckily, the locusts, experts say, are easy to control with chemicals. Kenya badly needs equipment and a steady supply of chemicals to effectively wipe out the massive insects. Hopefully, leaders worldwide will recognize the tough situation and contribute generously to control the locust outbreak.
1.What can we infer from what Cressman says in paragraph 2?
A.Little can dull locusts' appetite.
B.Urgent action must be taken against locusts.
C.Overpopulation in big cities leads to food shortages.
D.New York and California should meet challenges together.
2.What is paragraph 3 mainly about?
A.Locusts' living conditions. B.Locusts' destructive effect.
C.Locusts' daily travel distance. D.Locusts' super reproductive power.
3.For what purpose does the author mention "good conditions"?
A.To explain immediate causes of the locust outbreak.
B.To remind locals to preserve the environment.
C.To analyze how to prevent locust outbreak.
D.To highlight the strength of two rainstorms.

Each year, thousands of U.S. families open their homes and hearts to visitors from all over the world. In a homestay, students can observe, learn and experience a new lifestyle and culture, while practicing English skills in a home environment. Successful homestay experiences can help to ease homesickness for international students.1.
What makes homestays special is the daily experience of living with hosts who arc eager to share their way of life. Homestay hosts will reflect the diversity of the region in which they live. They may be single parents, retired couples or young families.2.What they will have in common is a desire to share their homes and their time with international students.
3.Most homestay hosts will give the student a list of simple house rules to help everyone live happily together. They may give guidelines about Internet usage, lawn勿(洗衣房), television viewing, meal times, keeping the bedroom and bathroom clean, and money matters.4.For example, at the University of Delaware, all homestay hosts living more than one mile from campus(校园)must provide transportation to and from campus every day of the week. Hosts must also provide each student with a private, furnished room which has a desk, a bed, a closet and enough lighting. Students will have access to a shared or private bathroom as well.
There is no better way to gain special insight into U.S. culture, while improving English language skills, than by participating in a homestay. It's not only important to get high scores in English testing, but to also learn how to get along with people from all over the world.5.
Occasionally, problems arise that cannot be solved. In these cases, the student can ask for another homestay or explore other housing options. The homestay coordinator(协调员)will work closely with the student to ensure that the next homestay will be a good match.

B.Living in a homestay will always require an adjustment period.

阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。续写的词数应为150左右。
Misha had a two-year-old dog called Gandalf, a search and rescue dog. Misha had trained him for a year with South Carolina Search and Rescue Dog Association.
Misha would train Gandalf whenever she had time. She would give him something like a shoe to smell, then hide it and say to him, “Find, boy!” Hearing this, Gandalf would race off. Soon he would turn up with the very object in his mouth, looking up at her and wagging(摆动)his tail happily. Misha was sure that together, they two would make a brilliant team.
Last Sunday, a 12-year-old boy Michael disappeared from his group's campsite in Doughton Park, 7000 rough acres in the Blue Ridge Mountains in North Carolina. A massive search had been launched, but for 3 days there was barely a track of the boy. The rescue teams were about to lose hope when Misha and Gandalf stepped in.
But this was their first real job. Gandalf would have to pick up the missing boy's smell in the air after three days, a challenging task for even the sharpest animal.
Misha gathered her team of six other members, and they headed north. A sister team had been searching the woods through the night. Misha's team would take over later that rainy morning.
All the searchers found were some dropped potato chips west of Michael's campsite. They'd obtained an unwashed T-shirt from Michael's backpack that hadn't been touched by anyone else and handled it with gloves, carefully cutting it into smaller pieces and sealing(密封) them up in plastic bags.
At 8 a.m. Misha's team were briefed on every detail about Michael. Misha carefully studied his picture to lock his image in her mind. She pulled a bright yellow jacket over Gandalf's head. It had large letters on each side saying “RESCUE”, which made Gandalf look like a solider.
Paragraph 1
Then Misha opened a bag containing the pieces of Michael's shirt.
_________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Paragraph 2
The rescue team were about to stop when Gandalf suddenly slowed down nearby a ruined castle (城堡)
