I had been fllwing the yellwish-green markers fr a “ppular and easy” three-mile ut-and-back hike (远足).Immediately after the trailhead，the trail(小径) became very rcky and steep.But having read abut the hike，I knew within five minutes，I was suppsed t reach the hike’s first verlk.
Hwever，the verlk never arrived.Instead，I fund myself lst in the wds.Pulling ut my cellphne，I saw it read “n service”.I checked the last text message I’d sent t my mm.It read，“Cnference fr a small hike befre my flight hme this afternn.” I put my phne away and kept mving and yelling，“Help! Is anybdy ut there？” Every s ften，I’d stp t listen，but I never heard a reply.
I gt ut my phne again.The battery was running ut fast as it searched fr a signal，I struggled t find a place where I culd get service.When I did，I called my mm.It went thrugh! In a shaky vice，I said，“Mm？” and then the call drpped.Mre than 1,500 miles away，my mm instantly knew smething was wrng.She called the Denver Plice Department and was directed t the US Frest Service.
This was hw I was intrduced t Jhn，an peratr frm the US Frest Service.Fllwing Jhn’s instructin n the phne，I finally escaped frm the wds.I breathed a sigh f relief.Then my phne rang，and it was Jhn，making sure I was still ging in the right directin.“By the way，” he said，“we’ve had yur mther n hld this whle time.S nce yu get dwn the muntain，yu will abslutely want t give her a call.”

In a study published in the U.S. jurnal Science，researchers frm the Chinese Academy f Agricultural Sciences(CAAS) and the University f Flrida identified the chemical cmbinatins and genetic recipe fr better tmat flavr(味道).
“In recent years，cnsumers ften cmplain that the mdern tmat is less flavrful than it nce was，” said c-principal researcher Sanwen Huang.“Our results prvide a practical rad map fr breeding tmat varieties with better flavr.”
Fr the study，a 170-persn cnsumer grup was created t evaluate 160 tmates representing 101 varieties，based n qualities such as “verall liking” and “flavr degree”.The results pinted t dzens f chemical cmpunds f interest，and further research using a statistical mdel discvered 33 flavr cmpunds cnnected with cnsumer liking，such as glucse(葡萄糖).The reasn why mdern tmates dn’t taste gd anymre is that a ttal f 13 f these flavr-assciated cmpunds “were significantly reduced in mdern varieties”，their paper wrte.Mrever，the researchers fund that smaller fruit tended t have greater sugar cntent，suggesting that “selectin fr mre sizable tmates has cst sweetness and flavr”.
Based n this knwledge，Huang and Prfessr Harry Klee f the University f Flrida studied the whle genmes f 398 varieties f tmat，identifying abut 250 psitins f genes n a chrmsme(染色体)，which cntrlled tmat flavr.
“We’re just fixing what has been damaged ver the last half century t push them back t where they were a century ag，” said Klee in a statement.“We can make the supermarket tmat taste nticeably better.” Klee said new tmat varieties with better flavr culd be ready in three t fur years.In additin，“the genes and pathways identified here in the tmat almst certainly pint t pathways wrth researching fr imprvement f flavr quality in ther fruit crps，” they wrte.
5.Accrding t the text，the study .

解析 细节理解题。根据倒数第二段中的“ abut 250 psitins f genes n a chrmsme(染色体)，which cntrlled tmat flavr.”可知，一些染色体上基因的位置控制西红柿的味道。故B正确。
7.What is the influence f the study accrding t the text?
