A NASA-funded study used satellite to search for penguin poops （糞便） in Antarctica：funny at first sight though，it resulted in unique insights on the Adelie penguin's diet and its future as the climate changes.The findings published recently unlocked the secrets about the species that can provide an early-warning of threats to Antarctica's delicate ecosystem.
   Researchers from Stony Brook University used satellite images to see if the Adelie penguin's diet has been changing in response to Antarctica's changing climate.Adelie penguin population has dropped greatly in some areas even as the global population increases.The satellite images cannot show the penguins individually，but their presence can be detected by the stain （污漬） left on the ice by their waste，called guano.
   Male and female penguins take turns incubating （孵化） in the nest.The guano builds up in the same areas occupied by the nests.Heather Lynch，associate professor at Stony Brook，along with his team，used the area of the colony as defined by the guano stain to work back to the number of pairs.A global survey for Adelie penguins turned up 3.8 million breeding pairs.Also，the satellite data can detect the color of the penguin guano，ranging from white to pink to dark red.White guano is from eating mostly fish；pink and red would be from eating mostly krill（磷蝦）.The team found that while the Adelie penguin's diet did show changes from year to year，no consistent pattern was obvious.
   "This was a big surprise，since the abundance and distribution of Adelie penguins has changed dramatically over the last 40 years and scientists had assumed that a change in diet might have played a role，" said Casey Young flesh，a graduate student from the university.However，continued changes in the physical environment and a growing krill fishery in the region are likely to have an influence on penguin prey（獵物）and penguin population itself. "Tools like this will be important for the management of the Antarctic ecosystem，which is often considered among the most primitive areas in the world，" said Young flesh.

1．The coronavirus（冠狀病毒）outbreak has sparked panic buying of toilet paper and cleaning products in countries across the world，but one UK businessman is determined to spread some happiness among the anxiety and confusion．
   Rob Braddick，48，who owns Braddick's Holiday Park in Westward Ho，Devon，in the southwest of England，has filled the toy grabber machines in his amusement park with two of the country's most sought-after cleaning products．

2．Malaria，the world's most widespread parasitic （寄生蟲引起的） disease，kills as many as three million people every year，almost all of whom are under five，very poor，and African.In most years，more than five hundred million cases of illness result from the disease，although exact numbers are difficult to assess（評估） because many people don't （or can't） search for care.It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment，and what they often get no longer works.In countries like Tanzania，Mozambique，and the Gambia，no family，village，hospital，or workplace can remain unaffected for long.
Malaria starts suddenly，with violent chills，which are soon followed by an intense （強烈的）fever and，often，headaches.As the parasites multiply（增加），they take over the entire body.Malaria parasites live by eating the red blood cells they infect （感染）.They can also go into blood vessels in the brain.If it doesn't kill you，malaria can happen again and again for years.The disease passed on to humans by female mosquitoes（蚊子） infected with one of four species of parasite.Together，the mosquito and the parasite are the most dangerous couple in the history of the earth.Malaria has five thousand genes，and its ability to change rapidly to protect itself from attack and resist（抵抗） new drugs has made it nearly impossible to control.Studies show that mosquitoes are passing on the virus more frequently，and there are more outbreaks in cities with large populations.Some of the disease's spread is due to global warming.
For decades，the first-choice treatment for malaria parasites in Africa has been chloroquine，a chemical which is very cheap and easy to make.Unfortunately，in most parts of the world，malaria parasites have become resistant to it.Effective medicines that help prevent resistance are already available，but they have been in short supply and are very expensive.If these drugs should fail，nobody knows what would come next.

（1）According to paragraph 1，many people don't search for care because

.
A．they are too poor
B．it is unusual to seek care
C．they can remain unaffected for long
D．there are too many people suffering from the disease
（2）People suffering from malaria

.
A．have to kill female mosquitoes
B．have their red blood cells infected
C．have ability to defend parasites
D．have sudden fever，followed by chills
（3）Which of the following may be the reason for the wide spread of the disease？

A．Its resistance to global warming.
B．Its ability to pass on the virus frequently.
C．Its ability to protect itself from attack and resist new drugs.
D．Its outbreaks in cities with large populations.
（4）It can be inferred from the passage that

.
A．the effective drugs are not easily available to most people
B．no drugs have been found to treat the disease
C．malaria has developed its ability to resist parasites
D．nobody knows what will be the drug to treat the disease

3．For many kids，the Internet is at their fingertips．From computers to smartphones，a web of information is open to them．According to a new report，about three out of four kids aged 12 to 15 connect the Internet using a mobile device from time to time．Many younger kids are online too．
   Julian Zeitlinger，9，from New Jersey，uses his computer to watch videos and play games．To keep him safe online，his parents monitor his web use and discuss Internet safety with him． "I ask my parents whether something is nice or bad，" Julian says．
   Mobile devices offer more ways than ever to share personal information．The information can be dangerous in the wrong hands．A study found that 62% of children aged 8 to 17 have had an unpleasant online experience．
   Have you ever had to enter a parent's e-mail address when signing up for a website？That safety measure is there because of the Children's Online Privacy Protection Act （COPPA）．The law says sites for kids under 13 cannot collect personal information，such as a phone number or full name，without a parent's permission．
   This July，the Federal Trade Commission（FTC） will update COPPA for the first time since the law was created in 1998 when there were no smart phones．The nature of the way kids get online has changed，F(xiàn)TC lawyer Phyllis Marcus said．
   When the changes take effect，COPPA will apply to mobile devices and newer forms of advertising．It will expand what falls under "personal information" to include videos，photographs，and services that give users location．
   COPPA doesn't cover everything that can go wrong online．That is why kids and parents need to know what to look out for and to stop and think before sharing information online．
   "There is a misunderstanding that if a site is following COPPA，it is totally safe，" says privacy expert Shai Samet．He runs kidSAFE，which checks whether a site meets kidSAFE standards and is safe． "It's important that kids know how useful the Internet is but that it also can be dangerous if you are not careful．" he adds．

（1）Julian's parents check his web use to make sure

．
A．he doesn't watch too many videos
B．he doesn't play computer games
C．he controls his online time
D．he stays safe on the Internet
（2）What's one of the changes with COPPA？

A．It broadens the concept of personal information．
B．It prevents users from making their location public．
C．It covers everything that goes wrong online．
D．It says no to any kind of advertising．
（3）People often hold the wrong idea that

．
A．formal websites are always safe
B．the Internet is becoming safer and safer
C．COPPA can ensure their complete safety
D．daily checks prevent future online problems
（4）Why does the author write the passage？

A．To ask parents to look out for their kids．
B．To talk about online safety for children．
C．To introduce a new law．
D．To sell an online product．
