The two most important reasons a mosquito is attracted to you have to do with sight and smell.故選D。 6．閱讀理解 根據(jù)第二段中的“We have an enormous number of immune cells coursing through our body, a momentary break from production is fine. So, when our body needs extra energy, one of the places it goes is our immune function.”可知我們的身體里有大量的免疫細胞，暫時停止運作是可以的。s cold. What you need is to shift all available energy resources to your legs, with the hope that you will live to experience another cough or sneeze.根據(jù)最后一段說研究人員目前正在對鳥類進行實驗，這些鳥類的飲食中經(jīng)常含有彩虹色的昆蟲。conceal themselves when in dangerbrilliantly changeable or metallic colors are among the strongest factors in an animal39。 A good disguise keeps you hidden, right? Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金屬彩虹色) can visually puzzle predators, which allows colorful prey to survive another day. Those surprising results appear in the journal Scientific Reports.根據(jù)第三段中的“A third of the ice173。Food production can lead to about 20 percent of human173。Following a nationally remended diet can have similar impacts in different countries.B.

Research suggested that WiFi can now be used to estimate the volume of liquids such as water, acid, alcohol and other chemicals for explosive material. The study led by researchers at the Wireless Information Network Laboratory (WINLAB) in the School. of Engineering showed a wireless device with two to three antennas(天線)that could be fitted in existing WiFi networks.故選B。To explore the geography of the Larsen C ice shelf.（2）What do the underlined words this one in the fourth paragraph refer to? A. Last year, part of the Larsen C ice shelf calved (崩解) away, forming a huge icebergA68—which is four times bigger than London, and revealing life beneath for the first time. Now scientists say it is a race against time to explore these new ecosystems before they are transformed to the light. Marine biologist Dr Katrin Linse from the BAS is leading the mission.The Larsen C ice shelf.B. （2）考查詞義猜測。 privacy.s hard to set up expensive screening equipment like what39。impact nations, in general, you can see that, if you follow a nationally remended diet, despite the fact that these diets don39。 Overall, in high173。Following a nationally remended diet can do good to our health.C.caused greenhouse gas with only a third of the ice173。free land on Earth is used for agriculture, and according to some estimates, producing food accounts for roughly a fifth of all human173。s concealment39。D.實驗?zāi)康氖强纯带B類的視角是否能提供幫助。因此，當(dāng)我們的身體需要額外的能量時，（我們的身體）會去找免疫系統(tǒng)。Such chemicallybased storage materials, known as Solar Thermal Fuels(STF), have been developed before. But those earlier efforts were designed to be used in liquid solutions and not able to make durable (耐用的) solidstate films. The new approach is the first based on a solidstate material, in this case a polymer, and the first based on inexpensive materials and widespread production technology.（1）What is the main purpose of Paragraph 1? show the main idea of the passage. practice readers39。 【點評】本題考點涉及細節(jié)理解和推理判斷兩個題型的考查，是一篇科普類閱讀，考生需要準確捕捉細節(jié)信息，并根據(jù)上下文進行邏輯推理，從而選出正確答案。t tell what your blood type is from a faraway place. Jonathon Day, a professor of medical entomology (昆蟲學(xué)) at the University of Florida in the US, told NBC it39。根據(jù)第四段中的“But heat will disappear over time no matter how good the material around it is, so the team set up a chemical storage system that can keep the energy in a stable molecular configuration. ”但是熱量會隨著時間的推移而消失，不管周圍的物質(zhì)有多好，所以研究小組建立了一個化學(xué)儲存系統(tǒng)，可以將能量保持在一個穩(wěn)定的分子結(jié)構(gòu)中)可推斷，這種分子結(jié)構(gòu)的優(yōu)勢是相對穩(wěn)定。 【點評】本題考點涉及推理判斷，詞義猜測和主旨大意三個題型的考查，是一篇科研類閱讀，考生需要根據(jù)上下文的邏輯關(guān)系，進行分析，推理，概括和歸納，從而選出正確答案。 （1）考查推理判斷。t need to waste energy making immune cells to fight off tomorrow39。 （3）考查推理判斷。catch the attention of their matesC.Coloration in the Animal Kingdom, already in 1909, that 39。 （2）考查詞義猜測。makes up for（3）Which of the following is TRUE according to the passage?

A.根據(jù)第四段中的“noting its design can inspect bags or luggage without being an exposure to privacy.”可知，不用打開和檢查人們的個人物品，避免了侵犯隱私，可知選D。B.To make full use of WiFi.C.It protects personal information from being disturbed.（3）Why did the researchers study the device according to Yingying Chen? A. The peerreviewed study, which recently won a best paper award at the 2018 IEEE Conference on Communications and Network Security, is now published online. Future work will continue to focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes, researchers said.（1）What does paragraph 3 talk about? A.根據(jù)第二段中的“Now scientists say it is a race against time to explore these new ecosystems before they are transformed to the light.”可知，科學(xué)家著急趕去世界最大的冰山是為了在其受到光照影響之前研究這座冰山下面的海洋生態(tài)系統(tǒng)。To explore a new way to prevent climate change.D.Climate change in Antarctica.C.根據(jù)第三段中的“The calving of A68 provides us with a unique opportunity to study marine life...”可知A68冰山的形成為科學(xué)家提供了研究海洋生物的獨一無二的機會，所以Professor David Vaughan認為科學(xué)家要果敢地抓住這次機會，故this one指的是A68冰山和它下面的生態(tài)系統(tǒng)。s in airports.
