Is there a link between scial media and depressin? D Facebk and Instagram have a negative impact n yur mental health? It’s cmplicated.
Smetimes, lking thrugh Instagram just makes yu feel bad. Yu try nt t envy yur friends, but they always seem t be traveling smewhere cl, eating smething fancy, r lking cute in perfect just-rlled-ut-f-bed hair. On the ther hand, there are times when yu laugh at funny memes (表情包) , catch up with ld friends, and feel happy t belng t fun scial media cmmunities, Clearly, scial media isn’t all bad.
Peple are increasingly suspect that there’re the ptential prblems f scial media. Things like cyberbullying, screen addictin, and being expsed t endless filtered images (美颜) that make it impssible nt t make cmparisns between yurself and thers ften make the news. In July, a big study came ut in the jurnal JAMA titled “Assciatin f Screen Time and Depressin in Adlescence.” This big headline seems t cnfirm what a lt f peple have been saying-screen time is hrrible fr yung peple.
The study fllwed ver 3800 adlescents ver fur years as part f a drug and alchl preventin prgram. Part f what the investigatrs measured was the teens’ amunt f screen time, including time spent n scial media, as well as their levels f depressin symptms.

That was true bth when the researches cmpared between peple and cmpared each persn against their wn mental health ver time.

Accrding t a recent study, a new kind f genetically mdified(转基因的) rice can prevent infectins f HIV, the virus respnsible fr the disease AIDS.
The study reprts the newly-develped rice prduces prteins(蛋白质) that attach directly t the HIV virus. This prcess keeps the virus frm mixing with human cells. The scientists say it can remve the effect f the virus and blck its spreading.
The Jint United Natins Prgramme n HIV/ AIDS reprts that wrldwide, nearly 37 millin peple were living with HIV in 2017. The rganizatin says the largest number f thse is in develping cuntries. Nearly tw-thirds f HIV cases are in Africa. Nw there is n cure fr HIV/AIDS thugh there have been develpments in ral drug treatments t slw the prgressin f the disease.
The new study predicts the rice-based methd will lead t lng-term use f the anti-HIV treatment acrss the develping wrld. Researchers say the "grundbreaking" discvery is "realistically the nly way" that anti-HIV cmbinatin treatments can be prduced at a cst lw enugh fr the develping wrld.
They say the easiest and mst cst-effective way t use the rice will be t make it int a cream t be put n the skin. The HIV-fighting prteins can then enter the bdy thrugh the skin. Peple all ver the wrld culd grw the rice and make the cream themselves. This wuld prevent the cst and travel required fr many patients t receive treatments and medicine.
The prcess f changing the genetic structure f fd crps has been debated fr sme time. Critics f genetically engineered crps believe they can harm peple. The scientific team says further testing is needed t ensure that the genetic engineering prcess des nt prduce any additinal chemicals that culd be dangerus t human bdies.
8．What is the third paragraph mainly abut?

C.The practical ways t cure AIDS.D.The effrts made by the United Natins.
9．Hw will the rice be used at the lwest cst?
A.By transfrming it int prteins.B.By prcessing it int a cream.
C.By attaching it t the HIV virus.D.By adding it t an ral drug.
10．What can we knw abut the genetic engineering prcess?
A.It wn't prduce dangerus chemicals.
B.It has prduced dangerus chemicals.
C.It is intended fr the develped wrld.
D.It requires further testing t ensure the safety.
11．Frm which is the text prbably taken?

C.A scial web page.D.A health magazine.
In the rich cuntries f the West, the electric vehicle revlutin is well underway. Climate-cnscius cnsumers drive Teslas r Plestars fr reasns f mrality and fashin. Prer cuntries are als experiencing a wave f electrified trend. In Bangladesh, electric three-wheeler taxis, knwn as tuk-tuks, are rapidly replacing gas-pwered nes n the streets. Such electric vehicles are climate friendly, cst effective, and help reduce air pllutin.
Yet a glance under the hd (引擎盖) f these vehicles reveals a pisnus secret: each tuk-tuk runs n five massive lead-acid batteries, cntaining almst 300 punds f lead in ttal. Every year and a half r s, when thse batteries need t be replaced and recycled, abut 60 punds f lead leak int the envirnment. Battery recycling, ften at small-scale unregulated factries, is a highly prfitable but deadly business.
Lead is dangerus, and any expsure t it is harmful t human health. Lead that has entered the envirnment hurts peple n an extrardinary scale. The numerus ways lead enters air, water, sil, and hmes acrss the develping wrld — and the enrmus damage it des t human health, wealth, and welfare — causes ne f the biggest envirnmental crises in the wrld yet receives little attentin.
The Wrld Bank estimates that lead kills 5. 5 millin peple per year, which wuld make it a bigger glbal killer than AIDS, malaria, diabetes, and rad traffic deaths cmbined. On tp f the shcking deaths, the scial burden f lead pisning is extrardinary, as is its cntributin t glbal inequality — ur research n the cgnitive effects f lead pisning suggests that it may explain abut ne-fifth f the educatinal achievement gap between rich and pr cuntries.
But unlike many challenges faced by develping cuntries, lead pisning is a prblem that is fixable with sme attentin and a relatively mdest financial investment. Better mnitring, research, and rules can help prtect children all ver the wrld frm the dreadful effects f lead pisning and reduce the massive glbal csts it brings.
12．Hw des the authr describe the lead prblem in paragraph 2?
A. By making a cmparisn.B. By analyzing hidden causes.
C. By listing cnvincing numbers.D. By explaining its wrking principle.
13．What can we learn frm the text?
A. Lead enters rich cuntries in varius ways.
B. Lead pisning may make pr scieties prer.
C. Expsure t lead desn’t necessarily harm smene.
D. Lead leaking has caused great panic in bth cuntries.
14．What can be dne t slve lead pisning in develping cuntries?
A. Fixing these used batteries.B. Putting certain effrt and mney.
C. Prhibiting the illegal use f lead.D. Reducing the cst f recycling lead.
15．Which f the fllwing is the best title fr the text?
A. The Impacts f Lead Pisning n Human Health
B. The Outcmes f Using Electric Vehicles
C. The Ways t Slve Lead Prblem
D. The Glbal Lead Pisning Crisis
二、七选五

32．答案：is knwn ；a ；envirnmental ；which；sharply ；int；has experienced ；cmpared ；visitrs ；lking
解析：①考查动词时态语态和主谓一致。句意:位于青藏高原的三江源地区是长江、黄河和澜沧江的源头，被称为"中国的水塔"。be knwn as"被称之为"，为固定搭配，描述现状，所以用一般现在时 态，主语为名词单数the Sanjiangyuan area。所以 be动词为is，故填is knwn。
②考查冠词。句意:它是独特的高原湿地生态系统，是国家重要的生态屏障。泛指一个，所以用不定冠词，unique是以辅音音素开头的，故填a。
③考查形容词。句意:几十年前，由于气候变化和人类活动导致三江源环境严重恶化，导致大量湖泊干涸，野生动物数量急剧下降。作定语修饰名词，所以用形容词，故填envirnmental。
④考查非限制性定语从句。句意:几十年前， 由于气候变化和人类活动导致三江源环境严重恶化，导致大量湖泊干涸，野生动物数量急剧下降。先行词为degradatin，指物，在非限制性定语从句中作主语，所以用which引导，故填which。
⑤考查副词。句意:几十年前，由于气候变化 和人类活动导致三江源环境严重恶化，导致大量湖泊干涸，野生动物数量急剧下降。修饰动词，所以用副词，故填sharply。
⑥考查介词。句意:为了使公园成为中国生态 文明进步的象征，人们付出了巨大的努力。"把……变成"，为固定搭配，故填int。
⑦考查动词时态和主谓一致。句意:多年来， 青藏高原的环境发生了很大变化。根据时间状语 Over the past years，可知用现在完成时态，主语为不可数名词the envirnment，所以助动词为has，故填has experienced。
⑧考查过去分词。句意:与10年前相比，该地 区今年的水资源保有量提高了11%。cmpared with"与……比起来"，为固定搭配，常用过去分词作状语，故填cmpared。
⑨考查可数名词的复数。句意:有些人做导游，帮助来自国内外的游客。表示"游客"，所以用visitr，为可数名词，前面没有限定词，所以用 名词复数表示泛指，故填visitrs。
⑩考查现在分词。句意:今天，当人们走在三 江源辽阔的土地上，望着山川、冰川、湖泊，看着野生动物和鸟类，他们不禁被大自然的辽阔和美丽所打动。lk和主语之间是主动关系，所以用现在 分词作状语，故填lking。
