19.Are you a social media addict?Are you always checking your smartphone to see how many‘likes'you've received for your latest post?Maybe you feel comforted by the notification sound that someone has sent you a message?Don't worry,you're not alone.We check our phones all average of 150times a day,and around 30%of the total time spent online is dedicated to social media.
Some experts now fear this habit could be damaging our mental health.This is something particularly affecting young adults,according to a study from the University of Pittsburgh.It found the more they used social media,the more likely they are to be depressed.The study found that exposure to"highly idealised life of peers on social media causes feelings of envy".Some of us certainly feel sad when we're ignored on social media sites,or when we see someone else having a better time than us.But depression is a more serious condition,which has been getting significantly worse over the last 5-6years.You can get so hooked that it takes you away from your real relationships.Other research by Glasgow University found that those with higher levels of emotional investment in social media,and who use it at night,were more likely to feel depressed and anxious.
Despite these warning signs,why do some of us continue to keep clicking?Well,I suppose we all want to be liked and we don't want to miss out on a conversation that's taking place online.But we need to know when to switch off our virtual online world and connect with the real world instead.

29.According to the passage,what might be damaging our mental health?D
A.Using  smartphones  too frequently   
B.Getting too many'likes'.
C.Longing for more messages.
D.Being addicted to social media.
30.According to the research,people may feel depressed becauseA.
A.they thought others are living a better life
B.they believe they have no real-life friends
C.they are ignorant about social media.
D.they desire to be part of the real world
31.The underlined word"hooked"is closest in meaning toC.
A.depressed      
B.relaxed    
C.a(chǎn)ddicted
D.embarrassed.

7.Different peoples have different religions and cultures because of the different places they live and their different traditions and customs and history.
While Europe and the United States of America are considered the Western World,it's good to know there are some differences in culture.If you are considering moving to a European country,you will find the information below helpful as you plan your move.
One cultural difference is how the countries perceive(認(rèn)知)time and space.For example,a house in the United States that is 200 years old would be considered ancient.This is probably because America is a fairly young country.However,in Europe,something would not be considered ancient unless it was at least 2,000 years old.However,perception of distance seems to be the opposite.While Europeans would consider 100 kilometres a long way to drive,Americans would not think twice.This could be due to the fact that Europe is smaller and more heavily populated.In fact,the United States is over twice the size of Europe.
Cars are another factor that differs greatly between Europe and the United States.American automobiles usually have automatic transmissions(自動(dòng)變速器)while European cars generally have manual gears(手動(dòng)變速器).European automobiles are smaller and more round-shaped,while American cars are larger and more square-shaped.Trucks and limousines(豪華轎車)are vehicles that Americans enjoy.In Europe,however,these types of vehicles are hardly seen,as they prefer smaller cars due to parking and traffic congestion.
The view of education is another cultural difference between the European countries and the United States.In America,parents may save for many years and even go into debt to pay for their children to attend college.Most schools and universities in Europe,however,are free of tuition.In fact,children are expected to attend college there.

25.The author wrote the second paragraph mainly toC.
A.tell the differences between Europe and America
B.a(chǎn)dvise people to travel to Europe and America
C.introduce the topic of this passage to the readers
D.persuade people to live in a European country
26.Which of the following shows the Americans'perception of time?A
A.An ancient house has a history of 200 years.
B.Europe has been at least 2,000 years old.
C.A hundred kilometres is a long way to drive.
D.It is proper to drive a distance of 100 kilometres.
27.It can be concluded from the last paragraph thatD.
A.Americans are richer than Europeans
B.Americans work harder than Europeans
C.the children in Europe needn't go to school
D.it costs Americans a lot of money to go to college
28.The author develops this passage byC.
A.a(chǎn)rguingB.persuadingC.comparing    D.doubting.
