20、A password management service, like Dashlane or PasswordBox, can help you keep track of hard passwords.”可知，密碼要經(jīng)常換。密碼管理服務(wù)軟件，像Dashlane 和 PasswordBox會幫助用戶很容易儲存和保護(hù)密碼，使得黑客難以攻破。故B項切題。 3．F　上下文銜接題。因為在電腦中你發(fā)送和儲存的信息會保持幾天或幾個星期，所以“It is very easy for anyone who sees that information to steal a detailed record o

21、f your online activities.(很容易讓人竊取你在線活動的詳細(xì)記錄)”。故F項切題。 4．E　上下文銜接題。很多公眾場合都提供免費(fèi)的網(wǎng)絡(luò)路徑。所以“Often, a user does not need a password to connect to these wireless networks.(用戶不用密碼就可以進(jìn)入網(wǎng)絡(luò))” 。故E項切題。 5．D　上下文銜接題?！癟here are many antivirus services available for users.(電腦用戶有很多殺毒設(shè)施)”，所以它們給電腦提供多種多樣的保護(hù)。故D項切題。 Ⅲ.語法填空

22、 (2017哈爾濱師范大學(xué)附屬中學(xué)調(diào)研) Online shopping is coming into fashion in most cities, where people are able to make full use of the rapidlydeveloped internet technology.

26、ed. 答案與解析 網(wǎng)購現(xiàn)象越來越普遍，文章講述了其原因、優(yōu)缺點(diǎn)及如何使之更規(guī)范。 1．who/that　考查定語從句。句意：現(xiàn)在你能找到?jīng)]有網(wǎng)購體驗的人嗎？定語從句中先行詞a person指人，從句可用who/that引導(dǎo)且在從句中作主語。故填who/that。 2．is welcomed　考查時態(tài)語態(tài)。句意：因為各種原因網(wǎng)上購物被很多人歡迎。online shopping與welcome之間為被動關(guān)系，且主語為單數(shù)，故應(yīng)用被動語態(tài)。故填is welcomed。 3．whatever/what　考查連接代詞。句意：只是點(diǎn)擊鼠標(biāo)，他們能在家里就得到想要的東西。what/whatev

27、er引導(dǎo)賓語從句，并在從句中作賓語。故填what/whatever。 4．Compared　考查非謂語動詞。句意：和傳統(tǒng)的交易模式相比，他們不用花錢租房子。compared with“與……相比”，是固定用法。故填Compared。 5．However　考查副詞。根據(jù)上下文可知，句子前后為轉(zhuǎn)折關(guān)系，且用逗號隔開，應(yīng)用副詞however。 6．the　考查冠詞。句意：人們失去討價還價的樂趣。特指“討價還價的樂趣”用定冠詞。故填the。 7．It　考查代詞。句意：毋庸置疑，網(wǎng)購已經(jīng)成為現(xiàn)代社會中不可抗拒的潮流。it作形式主語，代替that引導(dǎo)的主語從句。故填I(lǐng)t。 8．of　考查介詞。句

28、意：我們需要制定相關(guān)的法律是非常緊急的。用be of＋抽象名詞＝be＋形容詞。故填of。 9．with　考查介詞。句意：隨著網(wǎng)上貿(mào)易的迅速增長。with復(fù)合結(jié)構(gòu)作伴隨狀語。故填with。 10．convenience　考查名詞。由空前的pleasure可知此處應(yīng)填名詞形式與之并列。故填convenience。 Ⅳ.短文改錯 (2017閬中中學(xué)校檢測) My father and I enjoy fishing.
