一、核心詞匯與短語解析1.重點(diǎn)單詞allow：動詞，意為“允許；準(zhǔn)許”。常用結(jié)構(gòu)：`allowsb.todosth.`（允許某人做某事）；`beallowedtodosth.`（被允許做某事）。例句：Parentsshouldallowteenagerstomaketheirowndecisions.（父母應(yīng)該允許青少年自主做決定。）wrong：形容詞，表“錯誤的；不對的”。常用搭配：`What'swrong(with...)?`（……怎么了？）；`bewrongabout...`（對……判斷錯誤）。relation：名詞，意為“關(guān)系；聯(lián)系”。其衍生詞`relationship`更側(cè)重“人際關(guān)系”。例句：Therelationbetweendietandhealthisclose.（飲食與健康的聯(lián)系很緊密。）argue：動詞，意為“爭吵；爭論”。常用搭配：`arguewithsb.`（與某人爭吵）；`argueabout/oversth.`（就某事爭論）。例句：Don'targuewithyourbrotheroversmallthings.（別為小事和弟弟爭吵。）2.重點(diǎn)短語lookthrough：意為“快速查看；瀏覽”。例句：Ilookedthroughthetextbooktofindthekeysentences.（我瀏覽課本找重點(diǎn)句。）bigdeal：意為“重要的事”，常用于否定句或疑問句。例句：It'snotabigdeal.Let'ssolveittogether.（這不是大事，我們一起解決吧。）workout：意為“解決；成功發(fā)展”。例句：Weneedtoworkoutawaytoimproveourgrades.（我們需要想出提高成績的辦法。）getonwith：意為“和睦相處；關(guān)系良好”。例句：Howdoyougetonwithyournewclassmates?（你和新同學(xué)相處得怎么樣？）insteadof：意為“代替；而不是”，后接名詞、代詞或動名詞。例句：I'lltakeabusinsteadofwalking.（我會坐公交而不是走路。）二、語法知識精講1.情態(tài)動詞should/shouldn't的用法表建議/勸告：should意為“應(yīng)該”，shouldn't意為“不應(yīng)該”，后接動詞原形。例句：Youshouldlistentoyourteachercarefully.（你應(yīng)該認(rèn)真聽老師講課。）；Weshouldn'tcopyothers'homework.（我們不應(yīng)該抄作業(yè)。）表推測：should可表“按常理應(yīng)該”，語氣較委婉。例句：Thebusshouldarriveinfiveminutes.（公交車應(yīng)該五分鐘后到。）2.提建議的常用句型Whydon'tyou...?后接動詞原形，相當(dāng)于`Whynot...?`，語氣委婉。例句：Whydon'tyoujointheEnglishclub?（你為什么不加入英語俱樂部？）Whatabout...?/Howabout...?后接名詞、代詞或動名詞，表“……怎么樣？”。例句：Whataboutgoingshoppingthisweekend?（這周末去購物怎么樣？）Couldyou...?語氣禮貌，表請求或建議。例句：Couldyoupleasehelpmewithmymath?（你能幫我學(xué)數(shù)學(xué)嗎？）You'dbetter(not)do...意為“你最好（不）做……”，表建議。例句：You'dbetternotstayuplate.（你最好別熬夜。）三、閱讀與寫作要點(diǎn)1.閱讀策略本單元閱讀圍繞“問題與建議”展開，閱讀時需：定位問題：圈出文中人物的核心矛盾（如`arguewithparents`、`feellonely`等）；抓取建議：關(guān)注含`should`、`could`、`whynot`等的句子，分析建議邏輯；總結(jié)主旨：結(jié)合問題與建議，提煉文章核心觀點(diǎn)（如“溝通是化解矛盾的關(guān)鍵”）。2.寫作指導(dǎo)（建議信）寫作常要求針對問題提建議，結(jié)構(gòu)參考：開頭：點(diǎn)明對方的問題（如`Iknowyouhavetrouble...`/`Youmentionedthat...`）；主體：分點(diǎn)提建議，用建議句型（`should`、`whynot`等）并補(bǔ)充理由（如`Because...`/`Itcanhelpyou...`）；結(jié)尾：表達(dá)祝愿（如`Ihopemyadvicehelps.`/`Thingswillgetbettersoon.`）。示例片段：DearTom,Iknowyouarguedwithyourfriendandfeelsad.Here’smyadvice:First,youshouldwriteheralettertosaysorry—thisshowsyoursincerity.Then,whynotinvitehertoplaybasketball?Itcanhelpyourelaxandrebuildyourfriendship.四、易錯點(diǎn)與易混點(diǎn)提醒1.allow的結(jié)構(gòu)混淆：`allowsb.todosth.`（允許某人做）：Theteacherallowsustousedictionaries.（老師允許我們用字典。）`allowdoingsth.`（允許做某事）：Thelibrarydoesn'talloweating.（圖書館不允許吃東西。）2.instead與insteadof：`instead`是副詞，放句末：Ididn'tgoout.Instead,Ireadabook.（我沒出去，而是讀了本書。）`insteadof`是介詞短語，后接賓語：Ireadabookinsteadofgoingout.（我讀書而不是出去。）3.getonwith與get
