現(xiàn)跨距離的即時連接）、“facilitatesglobalcollaboration,remotework”（促進(jìn)全球協(xié)作和遠(yuǎn)程工作）、“providesaccesstoawealthofinformationandresources”（提供豐富的信息和資源）以及“E-commercehasalsotransformedshopping”（電子商務(wù)也改變了購物方式）。選項(xiàng)D“enablesglobalcommunication,work,andaccesstoinformation”是對這些益處的綜合概括。選項(xiàng)A、B、C僅為文中的部分內(nèi)容。3.A*解析思路：文章第三段首句即提出“misinformationandfakenews”（虛假信息和假新聞）是互聯(lián)網(wǎng)的“majorconcern”（主要擔(dān)憂），并指出其“posesathreattoinformeddecision-makingandcanunderminetrustininstitutionsandexperts”（對明智決策構(gòu)成威脅，并可能削弱對機(jī)構(gòu)和專家的信任），這與選項(xiàng)A“isasignificantsourceofmisinformationandfakenews”直接對應(yīng)。選項(xiàng)B、C、D描述了互聯(lián)網(wǎng)的負(fù)面影響，但并非第三段的核心觀點(diǎn)，且未特指虛假信息問題。4.C*解析思路：文章第三段討論了社交媒體可能對心理健康產(chǎn)生負(fù)面影響，指出“socialmediacancontributetofeelingsofisolationandanxiety”（社交媒體可能導(dǎo)致孤立感和焦慮感），并解釋了原因如“constantcomparisontocuratedonlinepersonas”（與精心策劃的在線形象不斷比較）和“cyberbullyingandonlineharassment”（網(wǎng)絡(luò)欺凌和在線騷擾）。選項(xiàng)C“cannegativelyimpactmentalhealthduetosocialcomparisonandcyberbullying”準(zhǔn)確概括了第三段關(guān)于社交媒體與心理健康關(guān)系的主要內(nèi)容。選項(xiàng)A、B、D分別提及了成癮、注意力分散和隱私問題，雖然也是互聯(lián)網(wǎng)的負(fù)面影響，但并非本段討論的重點(diǎn)，或者未準(zhǔn)確概括本段的核心觀點(diǎn)。第二部分閱讀理解5.C*解析思路：文章首段明確指出氣候變化的“causesarelargelyrootedinhumanactivities,particularlytheburningoffossilfuelslikecoal,oil,andnaturalgas”（主要原因根植于人類活動，特別是燃燒煤炭、石油和天然氣等化石燃料），這些活動釋放大量二氧化碳。選項(xiàng)C“isprimarilycausedbyhumanactivitiessuchasburningfossilfuels”準(zhǔn)確概括了首段的核心信息。選項(xiàng)A、B、D描述了氣候變化的后果或影響，而非原因。6.B*解析思路：文章第二段詳細(xì)描述了全球變暖的具體影響，包括“morefrequentandsevereheatwaves”（更頻繁和嚴(yán)重的熱浪）、“Meltingicecapsandglaciers,acceleratedbyhighertemperatures”（受更高溫度加速融化的冰蓋和冰川）、“risingsealevels”（海平面上升）以及“oceanacidification”（海洋酸化）。選項(xiàng)B“includesrisingglobaltemperatures,meltingice,andsea-levelrise”涵蓋了第二段提到的多個關(guān)鍵影響（溫度升高、冰川融化、海平面上升），雖然未提及海洋酸化，但相比其他選項(xiàng)更全面地概括了該段內(nèi)容。選項(xiàng)A、C、D分別提及
