How do you wake up in the morning? Imagine you set an alarm on your phone or clock that goes off like this: beep beep beep. 1. The state is known as grogginess (东倒西歪). So, is there a better way to wake up? A recent study says yes. The answer is music. Researchers say alarms that have a melody can help people feel fresher in the morning.
Sleep inertia (睡后迟钝) is another term for grogginess. 2. Someone even has trouble getting moving again after sleeping. Stuart McFarlane was a lead writer of the study. He said people need to better understand sleep inertia’s harmful effects on human performance later in the day. The grogginess we may feel in the morning has been reported to last from two to four hours.
3. But for those who do, care should be taken when perform duties that require a top performance within this period. 4. The same is true for people like pilots and firefighters. Sleep inertia has been linked to major accidents including airplane and shipping crashes.
What makes musical alarms better for waking up? The researchers think the music may be more successful in reducing sleep inertia because it has several tones, compared to the single tone of a “beeping” alarm. 5.
No matter how you wake up, experts say, the amount of sleep you get also matters a lot.
A.It means a person has a heavy feeling when waking up.
B.This includes dangerous tasks like driving or riding bikes shortly after waking up.
C.That harsh sound may make it harder to shake off the sleepy feeling.
D.Not everyone will experience the full effect.
E.The unpleasant beep is expected to be successful at waking up a person.
F.The changes over time may help increase a person’s attention when waking from sleep.
G.People who wake up to musical alarms feel more awake and alert.
“Outer space is a frontier that inspires us and unites us more than anything else,” declared the US Assistant Secretary for Arms Control, Dr. Yleem Poblete. “And as we continue to push further into our own solar system, new businesses will be built to seize the endless possibilities before us.”
However, there are growing concerns about the possibility of intentional acts of aggression in space, warned Dr. Poblete. The United States has raised concerns for many years that Russia is seeking the development and placement of anti-satellite weapons. As recently as February 2017, a Russian Air Force Squadron Commander stated that Russia is developing new missiles with the intention of destroying satellites. Furthermore, we have read statements from the Russian Ministry of Defense that it is working on creating “a mobile attack anti-satellite system”.
Vladimir Putin (Russian President) has alluded to space weapons being more “acceptable in the political and military respect”. This behavior continues despite Russia stating many times that it places a high priority on the promotion of the draft “Treaty on the Prevention of the Placement of Weapons in Outer Space” or PPWT.
The problem with such a treaty, said Dr. Poblete, is that it's difficult to determine an object’s true purpose simply by observing it on orbit. At this time, there are no means of distinguishing many objects' behaviors from that of a weapon, making outer space arms control measures like those in the proposed PPWT impractical.
In short, said Poblete, the proposed PPWT does not reduce the potential for conflict from extending into outer space. Plus, Russia may be engaging in the very behavior it claims to seek to prohibit.
“We must take concrete steps to strengthen the stability and sustainability of space,” declared Dr. Poblete, “The draft PPWT is not the right approach to accomplishing that. It is a questionable document, proposed by a country [Russia] that has routinely violated its international commitments.”
1.What does America suspect Russia is doing?
A.Launching satellites for spying. B.Trading space weapons illegally.

A.They are hard to be identified. B.They are not regulated by common rules.

3.What does Dr. Poblete think of PPWT?
A.It is not specific enough. B.It will worsen international relationships.
C.Russia itself fails to observe it. D.We must work together to promote it.
4.What is mainly discussed in the passage?
A.Where the key to space safety lies. B.What alarms the US as to space safety.

There's no place like home. 'This English saying has much truth in it: the best place to be is surrounded by our treasured possessions and our loved ones and with a roof over our head. And for many young adults, it's the only affordable place to stay; somewhere where they can receive first-class service from mum and dad. But this comes at a price!
According to the UKS Office for National Statistics, about a quarter of young adults aged 20-34 live at home, and that figure has been growing. A survey found that 18% of adult children in the UK said they were moving back home because of debt, compared with 8% last year. More young people had lost their jobs, and others couldn’t afford their rent compared with the previous year. So, it's easy to see why they're increasingly becoming home birds.
The BBC’s Lucy Hooker explains that many returning adult children enjoy home comforts. These include cooked meals, a full fridge and cleaning, as well as their bills being covered by what is commonly called ‘The hotel of mum and dad’. But for the ‘hoteliers’, that's mum and dad, the survey found the average cost to them has gone up sharply, and that they are sacrificing luxuries and holidays to look after their ‘big kids’ Emma Craig from MoneySuper market says, “They’re trying to look after their children more. If your child comes home and you see them struggling financially, you feel more awkward asking them for rent or to contribute. It tugs on your heartstrings more.”
With parents spending around € 1, 886 on takeaway food, buying new furniture and upgrading their Wi-Fi for the benefit of their offspring, it's easy for the returning children to put their feet up and make themselves at home. That’s before they learn a home truth that one day it might be their own kids who'll be checking into the hotel of mum and dad!

2.What is the main reason for the increase of ‘home birds’?

3.What can we learn about the parents of those ‘home birds’?
A.They are enjoying family members' company.
B.They are spending less money on luxuries.
C.They are charging their kids for accommodations.
D.They are complaining about the poor Wi-Fi.
4.Which can replace the underlined phrase “a home truth” in Paragraph 4?
A.a hidden secret B.a private message
C.an unpleasant fact D.an extra information
Even in the best and most loving of times, families can feel impossibly confined (受限制的). Teens are irritable and furious. Parents are annoying and embarrassing. For Esther and her daughter Chaya, the tiny new coronavirus changed all that.
Esther was born in Wuhan-a dynamic and culturally rich place that she deeply loves but moved to the U.S. During the winter holiday, they went to Wuhan to visit Esther’s parents. Gradually at first, then more frequently, they noticed face masks on city streets. To be safe, they wore their own masks and stopped going to public gatherings. Then, suddenly the city was on lockdown. No one could leave. Their reservations home on a China Southern airlines flight were worthless. “I feared for my daughter’s life,” said Esther, “If it got worse, there could be chaos. She doesn’t speak much Chinese.”
For days, Esther repeatedly called and emailed for help. It was nonstop. She stayed online, checking all the time. Chaya felt distressed and helpless. It's awful seeing her mother go through that-without having anything she could do to help in the hotel.
Their luck changed with one email. For the 1,000 Americans stuck in Wuhan, there were 230 available seats on one outbound flight, it said. Esther bought two $1,100 seats. After a 12-hour wait at the airport, they got clearance to leave, and arrived at March Air Force Base, where they were isolated in two small connected rooms with a shared bath for two weeks. There were daily medical checkups, twice daily temperature checks and a 10 a m. briefing (简报). But there was no WiFi, TV or friends. For emotional support, Esther phoned her husband Haim, an engineering manager for Uber, and their two other children, ages 13 and 11.
Now home, they are basking in (沉浸于) the thrill of phone calls, TV interviews and a caring community. They’ve gotten little sleep. Suitcases remain unpacked. But anyhow, they have survived not just the outbreak of a virus but the unforgettable experience of mother-daughter togetherness.
