If you're homeless and looking for a temporary shelter in Hawaii's capital，expect a visit from a robotic police dog that will scan your eyes to make sure you don't have a fever.That's just one of the ways public safety agencies are starting to use Spot，a new robot that runs around with quick movement.
   The police officials experimenting with the four-legged machines say they're just another tool to keep emergency responders out of harm's way as they search for dangers.
   Joseph O'Neal，an officer of the Honolulu Police Department，said the robot has protected officers，shelter staff and residents by scanning body temperatures between mealtimes at a shelter where homeless people could quarantine （隔離） and get tested for COVID-19.The robot is also used to remotely interview individuals who have tested positive.
   The company that makes the robots，Boston Dynamics，says it's trying to do a good job of explaining to the public and its customers what Spot can and cannot do. "One of the most difficult tasks is accurately explaining the state of the technology to people who have never had personal experience with it，" said Michael Perry，vice president of the company.
   There are roughly 500 Spot robots now in the wild.Perry said they're commonly used by companies to check dangerous areas.Spot is also used to monitor construction sites，mines and factories，equipped with whatever sensor is needed for the job.
   It's still mostly controlled by humans，though all they have to do is tell it which direction to go and it can climb stairs or cross over rough areas.It can also operate autonomously，but only if it's already memorized a road and there aren't too many surprise obstacles （障礙）. "The first value that most people see in the robot is taking a person out of a dangerous situation，" Perry said.

  • 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

  • 菁優(yōu)網(wǎng)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．
