An important factor that plays a part in susceptibility (易受影响) to colds is age.A study done by the University of Michigan School of Public Health indicated the fact that seems to hold true for the general population.Babies are the group suffering most from colds, averaging more than six colds in their first years.Boys have more colds than girls up to age three.After the age of three, girls are more susceptible than boys, and teenage girls average three colds a year to boy's two.
The general frequency of colds continues to decline into adults.Elderly people who are in good health have as few as one or two colds annually.One exception is found among people in their twenties, especially women, who show a rise in cold infections(感染), because people to this age group are most likely to have young children.Adults who delay having children until their thirties and forties experience the same sudden increase in cold infections.
The study also found that economics (经济状况) plays an important role.As income increases, the frequency at which colds are reported in the family decreases.Families with the lowest income suffer about a third more colds than families at the upper end.Lower income generally forces people to live in closer quarters than those typically occupied by wealthier people, and crowding increases the opportunities for the cold virus to travel from person to person.Low income may also influence diet.The degree to which poor nutrition affects susceptibility to colds is not yet clearly proved, but an inadequate diet is suspected of lowering resistance generally.
1.What factors cause people to catch colds easily?
A. Age and pregnancy. B. Health and pregnancy.
C. Health and economics. D. Age and economics.
2.Why does the lowest income lead to the rapid spread of colds?
A. Because poor people can't afford to go to see a doctor.
B. Because balanced diet has definitely affected poor people.
C. Because people with the lowest income have limited living space.
D. Because cold virus don't have opportunities to travel in poor families.
3.How does the study prove that age plays a part in susceptibility to colds?
A. Using comparison. B. Using graphs.
C. Using description. D. Using argument.
4.What can you learn from the passage?
A. Families with the lowest income suffer less colds than rich families.
B. The general frequency of colds are likely to increase among the poor.
C. Women in their twenties are most likely to avoid cold infections.
D. The general frequency of colds continue to rise into the adults.

高三英语单项填空中等难度题查看答案及解析
Science fiction paints a future where robots play an important part in everyday life. A technology firm is trying to make that future a reality today with an affordable robot called Artibo. Artibo is small. Its brain, or AI block, is a cube (立方体)that fits in your hand. That block connects to a motor block and two silicon wheels. Assembled, it's about four inches tall.
Artibo is much more than just a robot that you program to move around. Artibo’s designers want it to provide companionship and be a resource for learning coding. With its camera, microphone and connection to a cloud-based AI, it can respond to voice commands or function like a walkie-talkie(对讲 机).It talks like a chatbot and can tell bedtime stories. It can even help you learn other languages!
Artibo isn’t quite ready for stores yet, though. It’s part of a crowdfunding project. Crowdfunding is a program where you put a request online to a crowd of people. Supporters can then pay large or small amounts to help you finish a project. Artibo will first be available to people who have paid to help bring it into production.
Using computer code to program your own toys is nothing new. LEGO first released a robot kit in 1998. Since then, programmable robots have become one of the best-selling units in the LEGO product line. Programming robots might sound comparable to rocket science, but anyone can program one using nothing more than a tablet or a smartphone and code blocks.
Code blocks allow you to program simple or complex commands by assembling visual blocks of code on the canvas ( 画 布 )of a computer screen. Just drag and drop a variety of code blocks from a programming menu, link them together, and watch how your robot responds. In Artibo’s case coding doesn’t stop there. Unlike other similar programmable toys, Artibo will also allow you to write your own code. So as your familiarity with coding increases, you won’t lose interest in Artibo.
1.According to the passage, the purpose of developing Artibo is .
A.helping people learn anything they want and providing companionship
B.providing a robot that can move, accompany and help people learn coding
C.chatting with people, telling bedtime stories and supplying languages
D.helping people raise money on line and creating programmable robots
2.What can be concluded from the passage?
A.Programming robots is not really complicated.
B.Programming robots is advanced like a rocket.
C.Programming robots can be used in smartphones.
D.Programming robots used in toys is not new at all.
3.The passage implies that _______.
A.People can program various orders even without code blocks.
B.Anyone can control Artibo freely unlike other programming toys.
C.The more familiar you’re with coding, the more you’ll like Artibo.
D.Artibo is popular in the world especially among young people.
