Then ne night my mther wke us up and said， "It is time!"We were said that my aunt wuld take care f us while she was at the hspital.I wanted t g，t，but she said I wuld cme later. "G back t sleep，" she said. "I will see yu sn with the new baby."

24．（8分）I enjy baseball and I like cheering fr the hmetwn team.S my sn and I decided t attend an evening f pstseasn baseball this week when the Arizna Diamndbacks hsted the Ls Angeles Ddgers.
If yu fllw baseball，yu knw the Diamndbacks lst the the their seasn ended that night.In that regard，the night was a bummer（失望）.But in every ther way，the evening was clse t perfect.
The crwd was cheerful.The weather was amazing.The fd was delicius.And the cnversatin was excellent.We make chices every day with ur financial resurces（财力资源）.But this particular night f baseball was a helpful reminder t me that experiences are almst always better than things.
Experiences result in greater happiness.Accrding t research，experiences result in lnger﹣lasting happiness than material pssessins（拥有）.The happiness prvided by new material pssessins is shrt﹣lived.Over time，peple's satisfactin with the things they buy decreases，whereas their satisfactin with experiences ver time increases.
.One reasn I enjy baseball s much，is undubtedly，because f the many memries I have watching it with my father.Grwing up in Suth Dakta，an annual trip with the family t watch the Minnesta Twins play was a highlight f summer.Decades later，I lk back n thse mments with great jy and fndness.I remember them far better than almst any f the physical gifts.
Experiences result in less clutter （杂乱） .Mst physical pssessins eventually becme a burden n ur lives.They take up physical space in ur hmes and mental space in ur minds.Experiences，n the ther hand，are accmpanied with little t n physical baggage.The nly thing I brught hme with me frm the game were a few phts n my phne.
Experiences prvide greater pprtunity t cnnect with ther peple.This is the nature f experiencing things with thers.
Because we enjy time tgether arund a cmmn purpse and activity fr an extended perid f time，we are affrded numerus pprtunities t talk and cnnect with ne anther.
Experiences result in greater mindfulness.In 2010，Matthew Killingswrth and Daniel Gilbert published an imprtant study in Science magazine.Their research cncluded that "a wandering mind（不专注的心）is an unhappy mind."And the greater a persn's ability t "stay present" in a given mment，the greater happiness they experience during and after.
Experiences result in less cmparisn with thers.Accrding t research dne by Ryan T.Hwell and Graham Hill，anther significant reasn experiences result in mre happiness than material pssessins is because experiences result in less cmparisn with thers.
（1）What can we learn frm the first three paragraphs？
A.Everything else was enjyable that night.
B.Diamndbacks lst the game in Ls Angeles.
C.The baseball seasn was a bummer that night.

25．（10分）Scientists at MIT （Massachusetts Institute f Technlgy） have managed t change spinach plants int natural sensrs which can detect （探测） chemicals used in bmbs.Using a cheap and small cmputer system，the spinach can even help send a warning email.
The secret t giving spinach these special pwers is nantechnlgy（纳米科技）.Nantechnlgy，r nantech，is a scientific area that deals with making r changing things that are super tiny.Nantech is measured in nanmeters ﹣ ne billinth f a meter.
The MIT researchers are interested in using nantech t give plants new abilities.
They say plants are already great at sensing their envirnment，since they take in water frm the grund，and react t chemicals in it.Plants als supply their wn energy，which the scientists can use t pwer their tiny experiments.
Fr this experiment，the scientists placed tw different kinds f nantech materials，tiny sensrs and carbn nantubes，int spinach plants.Nantubes were used t make the plants give ff a special light.
T get the tiny materials int the plants，the scientists put a﹣liquid cntaining，the.nan﹣materials （包含纳米材料的液体） n the bttm f the plant's leaves.That's where the plants take in carbn dixide gas.Then the plants tk in the tiny materials.
Once the tiny sensrs and nantubes were in the spinach leaves，the plant did the rest f the wrk.
The carbn nantubes in the leaves，using sme f the plant's energy，give ff a special kind f light.The scientists are able t detect this light by shining a laser（激光）at the plant's leaves and measuring the light.
As part f its natural prcess，the spinach plant pulls water thrugh its rts and int its leaves.If the water cntains certain chemicals that are used in bmbs，the sensrs in the leaves make the nantubes give ff a different kind f light.
By watching the plant clsely using a camera cnnected t a cheap cmputer，the scientists set up a system that can send a warning email if chemicals frm bmbs are detected in the water.
The researchers say it takes abut 10 minutes fr the plants t react t the chemicals.It is almst like having the plant talk t us abut the envirnment they are in.
The scientists say that in the future，their system culd even use a cell phne with its camera changed slightly.
Detecting chemicals used in bmbs is just ne f the many uses the researchers are explring.They've used plants t detect and reprt n several ther dangerus chemicals as well.
The scientists believe that in the future，such systems culd give farmers detailed infrmatin abut the health f the land water n their farms.
（1）Scientists gave spinach plants new skills thrugh .
A.pwer
B.chemicals
C.nantech
D.cmputer
（2）Which f the fllwing statements is TRUE abut the prcess f experiment？
A.Nan﹣materials are put in the rts f the plants.
B.Sensrs cntain special liquid fr plants t take in.
C.Nantubes give ff tight with the help f carbn dixide gas.
D.Dangerus chemicals are detected by the sensrs in the leaves.
（3）Frm the passage，we can learn that .
A.the energy f the plants helps make it happen
B.plants are gd at reacting t the envirnment
C.it takes the plants secnds t ntice chemicals frm bmbs
D.scientists are able t see the change in the leaves f the plant
（4）What can we infer frm the passage？
A.Spinach takes in chemicals t make bmbs.
B.P lants will serve farming better in the future.
C.Scientists can imprve cell phnes with spinach.
D.Scientists will put nantech t ther practical use.
（5）Which culd be the best title f the passage？
A.Plants' New Abilities Help Imprve Farming.
B.Spinach Plants Has Magic Pwers t Make Bmbs.
C.Nantechnlgy Taught Spinach t Send Emails.
D.Scientists Create Spinach that Can Test fr Bmbs.

The systematic review f 83 articles，published in the Jurnal f the American Academy f Child& Adlescent Psychiatry，fund that lneliness is related with depressin and anxiety（抑郁和焦虑）in children，and thse wh feel lnely fr lnger perids f time might be mre affected.
"There is evidence that lneliness can lead t later mental health prblems，up t 9 years later，" says Maria Lades，dctr f clinical psychlgy. "Lneliness has impacts n self﹣cnfidence and well﹣being."
"We knw that during the pandemic，children and yung peple have had limited pprtunities t see their peers...，" Lades says. "The evidence we had suggests that thse wh have experienced lng lneliness during lckdwn may be mre affected by mental health prblems like anxiety and depressin."
The review als listed " duratin f quarantine（隔离期），infectin fears，bredm，frustratin，lack f necessary supplies，lack f infrmatin" as factrs that"appear t increase the risk f psychlgical prblems." Schl clsures，which culd lead t islatin，culd als increase risk f anxiety and depressin.

"It is nt necessarily essential that all children and teenagers are ging t schl in persn，and in fact it may nt be safe fr children t attend schl at times during this cming year.Hwever，fr children nt physically attending schl，it is imprtant t build and maintain ther meaningful scial pprtunities."
He suggests helping children scialize via nline grup chats，vide calls，r scial media.Still，parents shuld keep an eye n kids' nline activities t ensure they're using them in a psitive way that will maintain scial cnnectins.
One f the first things parents r guardians can d if their child is feeling lnely is t talk t them.Puliafic recmmends checking in with them regularly abut hw they're feeling and asking them what culd help them t feel less lnely.
Kids might als benefit frm talking t a therapist （治疗师）."Appraches like cgnitive behaviur therapy（CBT）help yung peple t develp ways t manage their thughts and t try ut different ways f ding things t help them t feel better and enable them t d the things in life that they want t d，" Lades says，adding that there's als evidence that taking up a new hbby culd help yung peple feel less lnely.
