The basic science is a cmbinatin f thught and experiment called the scientific methd. It’s where yu start with an idea, create a way t prve r disprve yur idea, and shw what yu learned based n facts. Learning t fllw this prcess helps yu think lgically (逻辑地) and carefully. These imprtant thinking skills can be used in many areas f study. T give a child practice with these thinking skills is like giving vitamins (维生素) t a develping mind.
One f the greatest things we can teach ur children is t lve learning. Learning science is a great way t d s. Children are easy t be interested in science. Because much f science is handsn, it attracts mst children. Nthing makes a child sit up and take ntice like the “WOW!” f a great science shwing.

Parties and scial gatherings n lnger excite us the same way they nce did. This is nt due t a lack f desire t scialize, but the smartphne.
At parties, peple fcus mre n their smartphnes than n their drinks. Accrding t a recent study frm Internatinal Data Crpratin, ver half f all Americans have a smartphne and reach it the mment they wake up, keeping it in hand all day. In additin, t many peple are using smartphnes while driving, and as a result, they get int car crashes. 34 percent f teens admit t text while driving, and they cnfirm that texting messages is the majr interruptin while driving. Peple’s attachment (依恋) t their smartphnes is unbelievably becming mre imprtant than the lives f themselves and thers.
Just as drivers dismiss the imprtance f fcusing while n the rad, many peple als fail t recgnize the significance f human interactin. When with their friends, sme peple pintlessly (无谓地) check r send messages in the presence f their friends, which means that their friends are less imprtant. In additin, relying n ur smartphnes t make friends des nt give us the same advantages as making new friends in the real wrld. Facetface cnversatins will give us the chance t imprve ur cmmunicatin skills in the lng run.

The wrd r phrase that yu use t pen yur email accunt may prvide a key t yur persnality as well as t yur crrespndence (信件), accrding t a British psychlgist. Helen Petrie, prfessr f humancmputer interactin (交互作用) at City, University in Lndn, analysed the respnses f 1,200 Britns wh participated in a survey funded (提资金) by CentralNic, an Internet dmain name cmpany. The results were recently published n CentralNic’s website.
Petrie identifies three main passwrd “types”. “Family riented” respndents numbered nearly half f thse surveyed. These peple use their wn name r nickname, the name f a child, partner, r pet r a birth date as their passwrd. They tend t be ccasinal cmputer users and have strng family ties. “They chse passwrds that symblize peple r events with emtinal value,” says Petrie. One third f respndents were “fans”, using the names f athletes, singers, mvie stars, fictinal characters, r sprts teams. Petrie says fans are yung and want t attach themselves t the lifestyle represented by a celebrity. Tw f the mst ppular names were Madnna and Hmer Simpsn. The third main grup f participants are “cryptics” because they pick cnfusing passwrds r a randm (随机的) string f letters, numbers, and symbls such as “Jxa＋157”. Petrie says cryptics are the mst security cnscius grup. They tend t make the safest but least interesting chices.
Passwrds are revealing fr tw reasns. First, because they are invented n the spt. “Since yu are fcused n getting int a system, fr example yur email accunt, yu’re likely t write dwn smething that cmes quickly t mind,” says Petrie. “In this sense passwrds take advantage f things that are just belw the surface f cnsciusness. Als, t remember yur passwrd, yu pick smething that will stick in yur mind. Yu may uncnsciusly chse smething f particular emtinal imprtance.”
( )9. Hw did Petrie draw her cnclusins?
A. By bserving participants’ reactins.
B. By interviewing 1,200 peple.
C. By studying survey results.
D. By ding an experiment.
( )10. What d we knw abut peple whse passwrds are “family riented”？
A. They prbably have large families.
B. They are likely t be animal lvers.
C. They tend t be scial and emtinal.
D. They are prbably infrequent cmputer users.
( )11. What des Petrie say abut the “cryptic” grup?
A. They have strng safety awareness.
B. They lack imaginatin and creativity.
C. They change their passwrds regularly.
D. They can't think f an interesting passwrd.

Kids and science seem t be made fr each ther!
The basic science is a cmbinatin f thught and experiment called the scientific methd. It’s where yu start with an idea, create a way t prve r disprve yur idea, and shw what yu learned based n facts. Learning t fllw this prcess helps yu think lgically (逻辑地) and carefully. These imprtant thinking skills can be used in many areas f study. T give a child practice with these thinking skills is like giving vitamins (维生素) t a develping mind.
One f the greatest things we can teach ur children is t lve learning. Learning science is a great way t d s. Children are easy t be interested in science. Because much f science is handsn, it attracts mst children. Nthing makes a child sit up and take ntice like the “WOW!” f a great science shwing.
Science pens drs t many subjects at schl. Building lve fr science can be helpful in ther areas f study. Fr example, ne cannt lve science fr very lng withut becming gd at its language—math! S science encurages children t study math. An interest in science is an interest in hw things were nce understd cmpared t hw they are understd nw. Thus studying science lends itself easily t studying histry. And after yu d an experiment, yu need t write a lab reprt. Therefre, writing becmes an imprtant part f science.
Science is the basic thing fr much f ur life. The science f farming shws hw ur fd is prduced; bimedical science keeps us healthy; even ur beds these days are designed accrding t scientific facts. We almst eat, sleep and breathe with the help f science! When we prepare the next generatin (一代) f vters, creatrs, and plicy makers, it is imprtant t make sure they are nt nly cmfrtable but als gd at science.

Parties and scial gatherings n lnger excite us the same way they nce did. This is nt due t a lack f desire t scialize, but the smartphne.
At parties, peple fcus mre n their smartphnes than n their drinks. Accrding t a recent study frm Internatinal Data Crpratin, ver half f all Americans have a smartphne and reach it the mment they wake up, keeping it in hand all day. In additin, t many peple are using smartphnes while driving, and as a result, they get int car crashes. 34 percent f teens admit t text while driving, and they cnfirm that texting messages is the majr interruptin while driving. Peple’s attachment (依恋) t their smartphnes is unbelievably becming mre imprtant than the lives f themselves and thers.
Just as drivers dismiss the imprtance f fcusing while n the rad, many peple als fail t recgnize the significance f human interactin. When with their friends, sme peple pintlessly (无谓地) check r send messages in the presence f their friends, which means that their friends are less imprtant. In additin, relying n ur smartphnes t make friends des nt give us the same advantages as making new friends in the real wrld. Facetface cnversatins will give us the chance t imprve ur cmmunicatin skills in the lng run.

The wrd r phrase that yu use t pen yur email accunt may prvide a key t yur persnality as well as t yur crrespndence (信件), accrding t a British psychlgist. Helen Petrie, prfessr f humancmputer interactin (交互作用) at City, University in Lndn, analysed the respnses f 1,200 Britns wh participated in a survey funded (提资金) by CentralNic, an Internet dmain name cmpany. The results were recently published n CentralNic’s website.
Petrie identifies three main passwrd “types”. “Family riented” respndents numbered nearly half f thse surveyed. These peple use their wn name r nickname, the name f a child, partner, r pet r a birth date as their passwrd. They tend t be ccasinal cmputer users and have strng family ties. “They chse passwrds that symblize peple r events with emtinal value,” says Petrie. One third f respndents were “fans”, using the names f athletes, singers, mvie stars, fictinal characters, r sprts teams. Petrie says fans are yung and want t attach themselves t the lifestyle represented by a celebrity. Tw f the mst ppular names were Madnna and Hmer Simpsn. The third main grup f participants are “cryptics” because they pick cnfusing passwrds r a randm (随机的) string f letters, numbers, and symbls such as “Jxa＋157”. Petrie says cryptics are the mst security cnscius grup. They tend t make the safest but least interesting chices.
Passwrds are revealing fr tw reasns. First, because they are invented n the spt. “Since yu are fcused n getting int a system, fr example yur email accunt, yu’re likely t write dwn smething that cmes quickly t mind,” says Petrie. “In this sense passwrds take advantage f things that are just belw the surface f cnsciusness. Als, t remember yur passwrd, yu pick smething that will stick in yur mind. Yu may uncnsciusly chse smething f particular emtinal imprtance.”
( )9. Hw did Petrie draw her cnclusins?
A. By bserving participants’ reactins.
B. By interviewing 1,200 peple.
C. By studying survey results.
D. By ding an experiment.
( )10. What d we knw abut peple whse passwrds are “family riented”？
A. They prbably have large families.
B. They are likely t be animal lvers.
C. They tend t be scial and emtinal.
D. They are prbably infrequent cmputer users.
( )11. What des Petrie say abut the “cryptic” grup?
A. They have strng safety awareness.
B. They lack imaginatin and creativity.
C. They change their passwrds regularly.
D. They can't think f an interesting passwrd.
