8.Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of spinach to make him strong.People watched him,and they began to buy and eat a lot more spinach.Popeye helped sell 33percent more spinach than before!Spinach became a necessary part of many people's diets.Even some children who hated the taste began to eat the vegetable.
Many people thought that the iron in spinach made Popeye strong,but this is not true.Spinach does not have any more iron than any other green vegetable.
People only thought spinach had a lot of iron because the people who studied the food made a mistake.In the 1890s,a group of people studied what was inside vegetables.This group said that spinach had ten times more iron than it did.The group wrote the number wrong,and everyone accepted it.
Today,we know that the little iron there is in spinach cannot make a difference in how strong a person is.However,spinach does have something else which the body needs-folic acid.It is interesting to point out that folic acid can help make a person strong.Maybe it was really the folic acid that made Popeye strong all along.

25.Why did many people eat spinach after they saw Popeye the Sailor?A
A.They thought spinach made them strong.
B.They thought Popeye was funny.

A.made Popeye strong
B.was a green vegetable
C.had less iron than other green vegetables

27.The reading passage says that perhaps Popeye got his strength fromB.

D.exercise
28.Folic acid isA.

分析 從二十世紀三十年代動畫片《大力水手》的播映以來,菠菜成了人們餐桌上必不可少的一道菜,人們都認為菠菜所含的鐵會賦予人力量.事實上,菠菜里含的鐵并不比別的蔬菜多,只是菠菜中的葉酸才能夠使人身體強壯,在本文中作者揭示了這一事實.

解答 25.A,推理判斷題.動畫片中的大力水手吃了菠菜后會力大無窮,看過這個動畫片的人們也把菠菜當成了他們餐桌上一道必不可少的菜,由此推斷人們認為菠菜真的會讓他們身體強壯,所以選A.
26.D,細節(jié)理解題.根據(jù)文章第三段This group said that spinach had ten times more iron than it did.The group wrote the number wrong,and everyone accepted it.可知研究人員提出了菠菜比其他綠色蔬菜含鐵更多的觀點,答案選D.
27.B,細節(jié)理解題.根據(jù)文章末段It is interesting to point out that folic acid can help make a person strong.Maybe it was really the folic acid that made Popeye strong all along.可知葉酸會給人提供能量,或許大力水手的力量就是由此而來的,故答案選B.
28.A,推理判斷題.根據(jù)文章第四段spinach does have something else which the body needs-folic acid.可知folic acid(葉酸)是存在于菠菜中的,由此推斷答案選A.

點評 解答任務(wù)型閱讀理解題,首先對原文材料迅速瀏覽,掌握全文的主旨大意.因為閱讀理解題一般沒有標題,所以,速讀全文,抓住中心主旨很有必要,在速讀的過程中,應(yīng)盡可能多地捕獲信息材料.其次,細讀題材,各個擊破.掌握全文的大意之后,細細閱讀每篇材料后的問題,弄清每題要求后,帶著問題,再回到原文中去尋找、捕獲有關(guān)信息.最后,要善于抓住每段的主題句,閱讀時,要有較強的針對性.對于捕獲到的信息,要做認真分析,仔細推敲,理解透徹,只有這樣,針對題目要求,才能做到穩(wěn)、準.

2.Regarded as one of the English language's most gifted poets,John Keats wrote poetry that concentrated on imagery,human nature,and philosophy.Although Keats didn't receive much formal literary education,his own studies and passion brought him much success.Additionally,his own life situation influenced his poetry greatly.
   Growing up as a young boy in London in a lower middle-class family,the young John didn't attend a private school,but went to a public one.His teachers and his family's friends regarded him as an optimistic boy who favored playing and fighting much more than minding his studies.After his father's death in the early 1800s,followed by his mother's passing due to tuberculosis (肺結(jié)核),he began viewing life differently.He wanted to escape the world and did so by reading anything h e could get his hands on.
    At around the age of 16,the teenage John Keats began studying under a surgeon so that he too might become a doctor.However,his literary appetite had taken too much of his fancy,especially with his addiction to the poetry of Ehmund Spenser.He was able to have his first full poem published in the Examiner in 1816,entitled O Solitude!If I Must With Thee Dwell.Within two months in 1817,Keats had written an entire volume of poetry,but was sharply criticized by a magazine.However,the negative response didn't stop his pursuit of rhythm (韻律).
   John Keats'next work was Endymion,which was published in May 1818.The story involves a shepherd who falls in love with the moon goddess and leads him on an adventure of one boy's hope to overcome the limitations of being human.Following Endymion,however,he tried something more narrative-based and wrote Isabella.During this time,John Keats began seeing his limitations in poetry due to his own limit in life experiences.He would have to have the"knowledge"associated with his poems.His next work was Hyperion that would attempt to combine all that he learned.However,a bout (發(fā)作) with tuberculosis while visiting Italy would keep him from his work and eventually take his life in 1821.
24.John Keats'attitude towards life changed because ofB.
A.his early education from school    
B.the deaths of his parents
C.Edmund Spenser's poetry           
D.the criticism of a magazine
25.What is the common thing between John Keats and his mother?A
A.They died of the same disease.
B.They had a bad childhood
C.They read many books.
D.They showed strong interest in poetry
26.While pursuing his dream of becoming a poet at first,John Keats wasA.
A.determined      B.experienced C.knowledgeable       D.impatient
27.What do we know from the passage?B
A.Keats received little education at school.
B.Keats once had a chance of becoming a doctor.
C.In 1816 Keats spent two months writing a poem.
D.Endymion was about a real love story.

3.Being Authoritative (由權(quán)威的) ParentsPhrases like"tiger mom"and‘‘helicopter parent"have made their way into everyday language.Many of us find ourselves drawn to the idea that with just a bit more parental hard work and effort,we might turn out children with bright futures.But is there anything wrong with a kind of"overparenting style"?
Parental involvement has a long history of being studied.Many of the studies,conducted by Diana Baumrind,a famous psychologist at the University of California,Berkeley,have found that a good parent is the one who is involved and reacts to her child in a positive way,who sets high expectations but gives her child independence.These"authoritative parents"appear to hit the sweet spot of parental involvement and generally raise children who do better academically,psychologically and socially than children whose parents are not strict and less involved,or controlling and more involved.Why is this parenting style so successful?
Authoritative parents actually help improve motivation in their children.Carol Dweck,a social psychologist at Stanford University,has done research that indicates why authoritative parents raise more motivated children.In a typical experiment,Dr.Dweck takes young children into a room and asks them to solve a simple puzzle.Most do so with little difficulty.But then Dr.Dweck tells some,but not all,of the kids how clever they are.As it turns out,the children who are not told they're smart are more motivated to solve increasingly difficult puzzles.They also show higher levels of confidence and show greater progress in puzzle-solving.
As the experiment suggests,praising children's talents and abilities seems to shake their confidence.Dealing with more difficult puzzles carries the risk of losing one's status as"smart".Dr.Dweck's work strongly supports that of Dr.Baumrind,who also found that reasonably supporting a child's independence and limiting interference (干涉) causes better academic and emotional results.
The central task of growing up is to develop a sense of self that is independent and confident.If you treat your young child who is just learning to walk as if she can't walk,you reduce her confidence.Allowing children to make mistakes is one of the greatest challenges of parenting.It is easier when they are young.The potential mistakes carry greater risks,and part of being a parent is reducing risk for our children.
24.According to the passage,a"tiger mom"D.
A.helps her children realize their dreams      
B.speaks her children's everyday language
C.places reasonable expectations on her children   
D.pays close attention to her children's experiences
25.It is implied that controlling style of parenting mayC.
A.face more challenges of children         
B.foster independence in children
C.cause more problems in children              
D.lead to children's academic success
26.The example of the children doing the puzzles suggests thatB.
A.a(chǎn) good game plays a big role in training young minds
B.overpraising makes children less motivated a nd confident
C.puzzle-solving can give children the motivation they need
D.bright children usually show less confidence in difficult games
27.The last paragraph tells us thatC.
A.children should not be given much freedom
B.parents should not increase the risk of challenging
C.parents should allow their children to learn from mistakes
D.children should correct mistakes with the help of their parents.
