1、精选优质文档-倾情为你奉上科教科普类1、 Australia leads the world in its number of resident poisonous spiders as well as the strength of their toxicity(毒性). However,of almost 9,800 species most are perfectly harmless and interesting. Spider diversity is broad and many fascinating species occur here that range from the
2、 large to the tiny and hardly noticed, and from the dullest black to the strangely shaped. Spiders can be roughly classified according to the strategies(策略) they use for feeding. Spiders which appeared earlier in the evolutionary scale feed by waiting in a cave for food to come along before grabbing
3、 it. Following them were spiders which actively wandered looking for food and which caught it by chasing it down. The evolution of flying insects makes spiders evolve new ways of catching food which couldnt be chased and so the earliest air web weavers arose. Most spiders feed on insects and other a
4、rthropods but the Whistling Spider feeds on frogs and small birds. The Golden Orb Spider also feeds on small birds. A spider periodically sheds(蜕皮;脱落) its skin so that it can grow. Immature stages are called moults. Each species has a particular number of moults that it will go through before reachi
5、ng its final adult stage. Usually, once male spiders have mated, they die shortly after. But, even in death, Redback males often serve a purpose. The already pregnant Redback females always kill their lover and, in most cases, also eat them. This provides them with a small reproductive advantage. Al
6、lowing spiders to take up places around houses can be beneficial in that they catch other annoying insects such as mosquitoes and flies. Rest assured that while you might see some large spiders, and perhaps even some poisonous ones, a good rule is to look and admire but dont touch any spider you fin

Language expert
10、s,however,will tell you that youre never too old to learn a new language. As you get older, it can be more difficult to learn a new language,though. Children and adults learn new languages in different ways. For children, language is their life. They study for thousands of hours every year. Because
11、they need to learn language to became part of their communities.Adults,on the other hand,are already part of a language community. Learning a new language means becoming part of another language community,and adults rarely get the chance to practice as much as young children do. Moreover.children le
12、aning a new language are expected to make mistakes. This gives them freedom when learning to be daring and confident Adults,however,often feel pressured to be perfect when learning a new language.This can discourage many people and make it even harder to learn a new language. When young children lea
13、rn a new language,they come to see various languages as a “normal” part of society.This mindset(思维模式) helps them embrace learning a new language without feeling like theyre doing something unusual or“too hard”. So if you want to learn a new language,go for it! Its never too late to learn a new langu
14、age. If youre older,it may take more work,but it can be done.If youre a young child,though,now is the time to step out and learn a new language!1.By “Language is their life”,the author means that children .A.cant live without languageB.lead a happy life every dayC.practice a new language a lotD.are
15、taken good care of adults2.What may make it hard for the old people to learn a new language!A.They are afraid of being laughed at.B.They usually have too many interests.C.They think making mistakes is natural.D.They always make all kinds of mistakes.3.Which of the following shows the difference betw

17、ood only by the old peopleD.can learned by both the old and the young3、 Kids and teens are often dismissive of praise from their parents. I am sure that parents out there can relate to this, as we all have been told at one time or another by one or several of our kids,“Stop it, Mom. or even,“Youre j
18、ust saying that because you are my parents and you have to say that. I can assure you, though, that they are listening. They will probably not thank you for this praise until they are in their twenties, but dont let that stop you from praising them during their childhood and teen years. Just be care
19、ful how you praise them. A little praise may go a long way especially if it is the right kind of praise. It appears that the way to go is to praise their efforts according to a study by Brummelman, of Utrecht University in the Netherlands and colleagues. These researchers concluded that kids should
20、be praised primarily for their efforts, rather than for their personal characteristics, because if they are praised for effort, then a poor performance is more likely to be seen as a glitch(小故障), rather than a valid reflection of who they are as individuals. Lets think about this together. If you ar
21、e a teenager or a child of any age and are constantly told how brilliant you are, then when you do poorly on a test or a few tests, you may feel like you have suddenly lost your status as brilliant and may now feel ashamed that you are merely average or even dumb. If you are a girl who is constantly
22、 being told how beautiful you are, then on a day when you dont look or feel so good, you may decide that you are unattractive. This is the problem that develops when we are praising our kids for global personality characteristics that they cant always live up to.1.According to the passage, which of
23、the following statements is the right kind of praise?A.You are a great artist.B.You are very intelligent.C.Wow, you have a special gift for music.D.Your painting has indeed improved due to your efforts.2.Which of the following statements is TRUE according to the passage?A.All the children should be
24、praised.B.Theres no need to praise kids and teens.C.Praise should be beyond childrens expectations.D.Teens often pay no attention to their parents praise.3.The underlined word “dumb” in the last paragraphcanbe replacedby _.A.stupidB.uniqueC.curiousD.honest4.The maintopicof this passageis _.A.why to
25、praise kids and teensB.how to praise kids and teensC.different ways to praise kids and teensD.the importance of praising kids4、 Scientists, psychologists and English academics at Liverpool University have found that reading the works of the classical writers like Shakespeare and Wordsworth has a gre
26、at effect on the mind, catches the readers attention and triggers moments of self-examination. Using a special machine, they monitored the brain activity of 30 volunteers as they read works by William Shakespeare, William Wordsworth, T.S. Eliot and others. In the first part of the research, the brai
27、n activity of 30 volunteers was monitored as they read passages from Shakespeares plays, including King Lear, Othello, Coriolanus and Macbeth, and again as they read the text rewritten in a simpler form or modern language. While reading the common texts, normal levels of electrical activity were sho
28、wn in their brains. When they read the works of Shakespeare, however, the levels of activity jumped because of his use of words which were unfamiliar to them. The result of the test showed that the more challenging passages cause a greater degree of electrical activity in the brain than the common o
29、nes. Scientists went on to study the brain activity as it responded to each word and recorded how it lit up as the readers came across unusual words, surprising phrases or difficult sentences in the classical works. As a result, this lightening up process of the mind lasted longer than that when vol
30、unteers read common texts, encouraging further reading. The research also found that reading poetry especially increases activity in the right hemisphere(半球) of the brain, an area connected with “autobiographical memory”, driving the readers to think carefully about their own experiences based on wh
31、at they have read. The academics said this meant the classical works of literature are more useful than self-help books. Philip Davis, an English professor who has worked on the study in the universitys magnetic resonance center, announced this week: “Classical literature acts like a rocket-booster
32、to the brain, which provides extra power for the brain. You may never imagine how powerful it is. The research shows such kind of literature can create new thoughts and connections in the young and the old.”1.The underlined word “trigger” in Paragraph 1 is closest in meaning to “_”.A.depends onB.pic
33、ks upC.sets offD.changes into2.Which of the following is NOT true about reading classical literature?A.It makes readers brain more active than reading common texts.B.It makes readers electrical activity of brain return to normal.C.Its helpful for readers to come up with new ideas.D.Its an activity t
34、hat is suitable for people of all ages.3.From the research, we can learn that _.A.the readers prefer Shakespeares works to the other writers worksB.the words of classical works make it hard for volunteers to read furtherC.reading classical works produces a good and long-lasting effect on the mindD.p
35、oetry increases left-brain activity more than other literary forms4.What does the author mainly tell us in this passage?A.Shakespeares plays deserve to be read.B.Common books are unpopular anymore.C.Poetry is best for developing peoples brain.D.Classical works help the brain develop better.5、 Do par
36、ents have a constitutional right to homeschool their children? No, according to a California District Court judge, who recently ruled that a child must be schooled by a person holding a valid state teaching credential (文凭)for the grade being taught”. What started as a Los Angeles County child welfar
37、e case involving one specific family has gone into proceedings (诉讼) that have actually put on trial the very nature of what constitutes a sound education. “For decades weve been happily homeschooling, and then this comes up suddenly,” says Mary Griffith, a homeschooling parent. Griffith says Califor
38、nia had traditionally given homeschooling parents the freedom to choose the kind of education they want for their child. This particular family in Los Angeles had enrolled their children in a private school independent study program not in their home. In response to abuse charges against the family,
39、 the children were enrolled in public schools. The parents stated they had a constitutional right to homeschool on religious grounds; thats when the court ruling was issued. However, Griffith says if the ruling ends up affecting anyone, it will mainly be those who also enroll their children in off-s
40、ite homeschooling. “This wont be far-reaching for homeschooling parents. Thats how organizations like the Homeschool Association of California (HSC) would like to keep it, anyway, and theyve hired a team of lawyers to limit the impact of the case. Griffith says the legal team for HSC is trying to es
41、tablish that while this ruling may indeed be necessary for this particular family, it should not set a precedent(先例) for all. What does this case really mean for homeschooling families nationwide? According to Darren A. Jones, this decision is certain to affect homeschooling on a national scale. Jon
42、es claims that it is common for state courts to look to other states rulings for assistance in deciding issues where no precedent exists. “A poor legal decision in California could become part of a trend across the nation.1.In Griffiths opinion, _.A.parents dont have a right to homeschool their chil
43、drenB.a child must be schooled by an expert with a credentialC.homeschooling should be forbidden in the whole countryD.it is understandable for parents to homeschool their children2.The underlined word “this” in Para. 2 refers to the fact that_.A.parents happily homeschool their childrenB.parents do

45、 the better education in it.C.To break away from their parents.D.To cooperate with the experts jobs.4.Whats the authors attitude towards whether parents have a right to homeschool their children?A.Supportive.B.Sympatric.C.Negative.D.Objective.6、 Summer shouldnt mean taking a break from learning, esp
46、ecially reading. Studies show that most students experience a loss of reading skills over the summer months, but children who continue to read actually gain skills. So efforts should be made during the summer to help children keep reading skills, practice reading and read for enjoyment. Parents shou
47、ld remember that children need free time in the summer to relax and enjoy the pleasures of childhood. So summer reading should be fun. Following are a few tips to make reading enjoyable for your children this summer: Read aloud together with your child every day. Make it fun by reading outdoors on t
48、he front steps, patio, at the beach or park. Also, let your children read to you. Set a good example! Keep lots of reading material around the house. Turn off the TV and have each person read his or her book, including Mom and Dad. Read the same book your child is reading and discuss it. This is the way to develop habits of the mind and build capacity(能力) for thought and insight. Let kids choose what they want to read, and dont turn your nose up at popular fict
