【解析】

短文大意：短文介紹了兩種制作和傳遞秘密信息的方法。

【1】題意：是什么讓“檸檬汁信”中的秘密信息出現(xiàn)的？考查細(xì)節(jié)理解。根據(jù)第一則3.Ask the person receiving your letter to hold the paper near the light. The light will make the secret message show up可知光會(huì)讓秘密信息顯示出來，故選B。

【2】題意：關(guān)于檸檬汁的信，哪個(gè)是正確的?考查細(xì)節(jié)判斷。A. 只有孩子能做到；文中沒有提及可知說法錯(cuò)誤。B. 信息中的文字一定是黃色的；根據(jù)Use the lemon juice to write a message on the paper.可知說法錯(cuò)誤。C. 當(dāng)你拿著檸檬汁靠近燈光時(shí)，它是棕色的；根據(jù)The lemon juice will turn brown.可知說法正確。D. 下雨的時(shí)候你什么也看不見；根據(jù)When it dries, you can’t see anything on the paper.可知說法錯(cuò)誤。綜合以上分析，故選C。

【3】題意：你不需要什么來制作鏡像信息?考查細(xì)節(jié)理解。根據(jù)第二則A mirror message/

What will you need: A potato/ A knife/ A bathroom mirror可知不需要紙張，故選A。

【4】題意：劃下劃線的單詞“invisible”是什么意思?考查詞義理解。根據(jù)下文When you take a bath, close the door. The hot air with water will make your message show.可知洗澡前看不見信息，故選D。

【5】題意：文章的中心思想是什么？考查主題理解。根據(jù)開頭Do you want to send a secret message? Here are two wonderful ways to do it可知，短文介紹的是制作和傳遞秘密信息的方法，故選B。

本文介紹了制作和傳遞秘密信息的方法，篇幅較長(zhǎng)，但內(nèi)容比較簡(jiǎn)單，各個(gè)小題都能在文中找到適當(dāng)依據(jù)。只要認(rèn)真閱讀短文，注意前后聯(lián)系，就能順利完成閱讀。主要考查細(xì)節(jié)理解，做題關(guān)鍵是找出原文的根據(jù)，認(rèn)真核查小題和原文的異同。小題4考查詞義理解，問劃下劃線的單詞“invisible”是什么意思；根據(jù)下文When you take a bath, close the door. The hot air with water will make your message show.可知洗澡前看不見信息，前三項(xiàng)不合句意，故選D。
