Diet Coke，diet Pepsi，diet pills，no-fat diet，vegetable diet...We are surrounded by the word "diet" everywhere we look and listen.We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us.We are paying for products that harm us psychologically and physically.
   Diet products significantly weaken us psychologically.On one level，we are not allowing our brains to admit that our weight problems lie not in actually losing the weight，but in controlling the consumption of fatty，high-calorie，and unhealthy food.Diet products allow us to jump over the thinking stage and go straight for the scale（秤）instead.All we have to do is to recognize and swallow the word "diet" on food labels.
   On another level，diet products have greater psychological effects.Every time we have a zero-calorie drink，we are telling ourselves without our awareness that we don't have to work to get results.Diet products make people believe that the gain comes without pain，and that life can be without resistance and struggles.
   The danger of diet products lies not only in the psychological effects they have on us，but also in the physical harm that they cause.Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients.Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products.Diet products may not be nutritional，and the chemicals that go into diet products are potentially dangerous.
   Now that we are aware of the effects that diet products have on us，it is time to seriously think about buying them.Losing weight lies in the power of minds，not in the power of chemicals.Once we realize this，we will be much better able to resist diet products，and thus prevent the psychological harm that comes from using them.

C

1．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(píng)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(qiáng)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

2．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．
   Customers could previously try their hand at grabbing "Frozen 2" or "Peter Rabbit" toys from the machines，but no more． "They got removed this morning，" Braddick said of the toys，replacing them with toilet roll and hand sanitizer （洗手液）．Visitors can now pay 50 p for three goes on the toilet roll grabber，or ￡1 a go for Carex，which Braddick described as the "Rolls- Royce of hand sanitizers．"
   Braddick said that his decision was born of a desire to make people feel less stressed in uncertain times． "It's a bit of light relief with everything that's going on，" he said． "Hopefully it will raise a smile，which I think everybody needs．"
   Around the world，travel plans have been severely affected，and tens of millions of people remain at home as part of global efforts to fight against coronavirus．Supermarkets have seen shortages of toilet paper and hand sanitizer as anxious consumers stockpile the products．
   Braddick said the family business，which has been running since 1932，has received more than a dozen calls from potential customers who say they don't want to travel abroad for their holidays and would rather stay in the UK．As for his own measures against coronavirus，Braddick said staff have been told to wash their hands every half hour，which is particularly important for those handling money．

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．
