【文章內(nèi)容簡(jiǎn)介】 and cause some of them to die. This is what causes hearing loss. Once this happens, it39。s hard to get your hearing back. Some people might think that their music isn39。t all that loud. But this can depend on where you are. For example, if you are in a noisy place like the subway, you might turn up your music too loud without realizing it. Later, when you listen to it at the same volume in a quiet place, you alight feel unfortable The safe level for most sound is below 80 dB for up to 40 hours a week. A level of 80 dB is about equal to （相當(dāng)于） the noise of a subway. Here is some advice on safe listening. Over—the—ear headphones （頭戴式耳機(jī)） are better than in—ear ones. They do a better job of stopping outside noise, so you can listen at a lower volume. Don39。t listen to loud music on your headphones for a long time. Follow the 60:60 rule: listen to music at 60 percent of your headphones39。 maximum volume for no more than 60 minutes a day.（1）It is safe to listen to sounds that are louder than 100 dB for 15 minutes （2）Listening to loud noise for a long time can cause some hair cells in the inner ear to die. （3）From the fourth paragraph, we know people don39。t always realize how loud their music is. （4）In—ear headphones are better than over—the—eat ones because they can stop more outside noise. （5）This article mainly tells us why ears are an important part of our bodies. 【答案】 （1）0（2）1（3）1（4）0（5）0 【解析】【分析】文章大意： 本文主要講述了聽(tīng)大音量音樂(lè)的習(xí)慣對(duì)聽(tīng)力有害。世界衛(wèi)生組織稱，超過(guò)10億的年輕人在聽(tīng)力方面存在問(wèn)題，因?yàn)樗麄冮L(zhǎng)時(shí)間大聲聆聽(tīng)。聯(lián)合國(guó)有安全聆聽(tīng)標(biāo)準(zhǔn)。聽(tīng)八十小時(shí)大于85分貝或15分鐘大聲100分鐘的聲音是不安全的。長(zhǎng)時(shí)間聆聽(tīng)大聲的聲音可能會(huì)使這些細(xì)胞工作太猛，并使其中一些細(xì)胞死亡。這就是人們聽(tīng)力損失的原因。 （1）判斷正誤題。根據(jù) It is not safe to listen to sounds that are louder than 85 dB （分貝） for eight hours or 100 dB for 15 minutes. 可知挺高于85分貝八個(gè)小時(shí)或者100分貝15分鐘是不安全的。故答案為錯(cuò)誤。 （2）判斷正誤題。根據(jù) However, listening to loud noise for a long time can make these cells work too hard and cause some of them to die. 可知聽(tīng)大聲的噪音很長(zhǎng)時(shí)間能使這些耳毛細(xì)胞工作太猛，造成一些耳毛細(xì)胞死亡，故答案為正確。 （3）判斷正誤題。根據(jù) if you are in a noisy place like the subway, you might turn up your music too loud without realizing it. 可知如果你在像地鐵這樣吵鬧的地方，你可能無(wú)意識(shí)的把聲音調(diào)到太大，可知第四段告訴我們?nèi)藗儾豢偸悄芤庾R(shí)到他們的音樂(lè)有多大聲，故答案為正確。 （4）判斷正誤題。根據(jù) Over—the—ear headphones （頭戴式耳機(jī)） are better than in—ear ones. They do a better job of stopping outside noise, so you can listen at a lower volume. 可知頭戴式耳機(jī)比置入式耳機(jī)更好，故答案為錯(cuò)誤。 （5）判斷正誤題。通讀全文可知大意是：聽(tīng)大聲的音樂(lè)對(duì)聽(tīng)力有害，不是講耳朵是人體重要的組成部分，故答案為錯(cuò)誤。 【點(diǎn)評(píng)】考查閱讀理解能力，首先通讀全文，掌握大意，然后根據(jù)細(xì)節(jié)判斷所給句子的正確，注意要找到依據(jù)。7．閱讀下列短文，從每題所給的A、B、C三個(gè)選項(xiàng)中選出最佳答案。 If you look at the top of your phone, you39。ll usually see a little symbol that says 3G or 4G. The G stands for the generation （代） of your mobile network. But the symbols will bee things of the past after 5G networks fully arrive. On March 30, Shanghai vicemayor Wu Qing made the first 5G video call on a Huawei Mate X Smartphone. Shanghai has also bee the first city in China to start testing 5G networks. About 100 times faster than 4G networks, 5G will let people download and upload data（數(shù)據(jù)） faster than ever before. But 5G won39。t just bring faster mobile internet. People can use it for many other things as well. For example, 5G will help to make selfdriving cars safer. Today39。s selfdriving test cars have one problemlag（延遲）. When the car sees an obstacle（障礙物）, it sends this information to a data center and receives instructions, However, it will be some time before it sends and receives this information. With this kind of lag, the cars might crash because they don39。t receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer.5G could also be used to power the internet of things （IoT）, that is, a large online network that connects all things and people. Fast internet speeds will be the key to developing this technology. The IoT could be used in a lot of ways. For example, with IoT, your refrigerator could automatically （自動(dòng)地） place an order online for eggs when it finds that there are no eggs left inside.（1）Which city was 5G tested for the first time? A.Beijing.B.Shanghai.C.Shenzhen.（2）What can we infer（推測(cè)） according to the passage?. A.5G is widely used in China now.B.5G networks will make our lives more convenient.C.There are no symbols at the top of our phones.（3）The writer uses selfdriving cars as an example to . A.explain how 5G39。s fast speed can be helpfulB.warn about the possible dangers of selfdriving carsC.explain how selfdriving cars work（4）What is IoT according to the passage? A.A robot that can do housework.B.An online store where you can buy anything.C.A large online network that connects things and people.（5）Which sentence is right according to the passage? A.5G will help us buy eggs quickly.B.Robots can help us buy eggs online.C.Our refrigerator can order eggs online for us.【答案】 （1）B（2）B（3）A（4）C（5）C 【解析】【分析】短文大意：當(dāng)人們看手機(jī)上方的時(shí)候，會(huì)看到3G或者4G的小符號(hào)。G代表手機(jī)網(wǎng)絡(luò)的代。但是，當(dāng)5G網(wǎng)絡(luò)全面覆蓋時(shí)，這些符號(hào)將會(huì)成為過(guò)去時(shí)。3月30日，上海市長(zhǎng)吳清第一次使用華為Mate X智能手機(jī)進(jìn)行視頻通話，上海成為中國(guó)進(jìn)行第一個(gè)測(cè)試5G的城市。5G將會(huì)在很多方面改善人們的生活。 （1）細(xì)節(jié)理解題。根據(jù) Shanghai has also bee the first city in China to start testing 5G networks?？芍?，上海是中國(guó)第一個(gè)進(jìn)行5G測(cè)試的城市。故選B。 （2） 推理判斷題。根據(jù)About 100 times faster than 4G networks， 5G will let people download and upload data（數(shù)據(jù)） faster than ever before。 But 5G won39。t just bring faster mobile internet。 People can use it for many other things well?？芍?，5G的速度將會(huì)是4G的100倍，人們下載或者上傳數(shù)據(jù)都會(huì)快很多。而且，5G不僅僅是在移動(dòng)網(wǎng)絡(luò)上給人們帶來(lái)快捷。在其他方面，人們也可以利用5G。由此可以推斷出，5G將會(huì)使人們的生活便利很多。故選B。 （3） 推理判斷題。根據(jù)…With 5G， this lag will be greatly lowered， making the cars safer?？芍?，5G可以大大減少問(wèn)題延遲，從而使無(wú)人駕駛汽車更安全。作者通過(guò)這個(gè)例子來(lái)告訴我們5G的告訴怎樣起作用的。故選A。 （4）詞義猜測(cè)題。根據(jù)5G could also be used to power the internet of things（IoT）， that is， a large online network that connects all things and people?？芍?，IoT指的是把所有人和物聯(lián)系起來(lái)的一個(gè)巨大的在線網(wǎng)絡(luò)。故選C。 （5）細(xì)節(jié)理解題。根據(jù)For example， with IoT， your refrigerator could automatically （自動(dòng)地 ） place an order online for eggs when it finds that there are no eggs left inside。可知，當(dāng)冰箱里沒(méi)有雞蛋時(shí)，冰箱可以自動(dòng)在網(wǎng)上下單買雞蛋。故選C。 【點(diǎn)評(píng)】此題考查閱讀理解?？陀^信息題可以從文章中直接找到答案。而主觀判斷題考查的是對(duì)文章的感情基調(diào)等，這類題必須經(jīng)過(guò)對(duì)作者的態(tài)度、意圖以及對(duì)整篇文章進(jìn)行深一層的推理等。通過(guò)語(yǔ)篇邏輯關(guān)系，研究細(xì)節(jié)的暗示，推敲作者的態(tài)度，理解文章的寓義。對(duì)于詞意猜測(cè)題。需要準(zhǔn)確無(wú)誤地理解上下文，根據(jù)上下文的聯(lián)系進(jìn)行猜測(cè)。找出問(wèn)題答案。8．閱讀理解 15 of 90 days / All 90 days Next 5 TODAYJUN 29SUNJUN 30MONJUL 1TUEJUL 2WEDJUL 321176。／13 176。CMostly cloudy19 176。／11 176。Partial sunshineMore19 176。／12 176。Clouds and sunMore20
