When the plane goes 35,000 feet high, 【3】 They help explain why the tomato juice on airplanes tastes far less sour in the air than it does down on the ground.【4】 Otherwise, the food would be tasteless.

【答案】

【1】D

【2】C

【3】A

【4】E

【5】B

【解析】

本文介紹了為什么飛機(jī)上的食物為什么不好吃的原因。部分原因是在高海拔地區(qū)，事實(shí)上我們不能像在地面上那樣好好地品嘗食物。主要原因是隨著飛機(jī)的爬升，氣壓也會(huì)發(fā)生變化，我們的鼻子也變得越來越麻木。當(dāng)飛機(jī)飛到3.5萬英尺高的時(shí)候，鼻子不再有知覺。

【1】句意：在空中吃點(diǎn)可口的東西對(duì)旅行者來說就像做夢(mèng)一樣。根據(jù)下文According to some recent scientific researches, a part of the reason is that at high altitude(海拔), we can’t actually taste things well as we do on the ground.（根據(jù)最近的一些科學(xué)研究，部分原因是在高海拔地區(qū)，事實(shí)上我們不能像在地面上那樣好好地品嘗食物。）結(jié)合句意（選項(xiàng)）可知是“在空中吃點(diǎn)可口的東西對(duì)旅行者來說就像做夢(mèng)一樣。”故選D。

【2】句意：飛機(jī)內(nèi)部的空氣使鼻子干燥。根據(jù)下文As the plane climbs, the air pressure changes and our noses become more and more senseless.（當(dāng)飛機(jī)爬升時(shí)，氣壓變化，我們的鼻子變得越來越麻木。）可知上文是關(guān)于鼻子的，可知是“科學(xué)家發(fā)現(xiàn)，即使在飛機(jī)起飛之前，飛機(jī)內(nèi)部的空氣使鼻子干燥�！� 結(jié)合句意（選項(xiàng)）可知選C。

【3】句意：鼻子不再有知覺了，就像被蛇咬傷一樣。根據(jù)上文As the plane climbs, the air pressure changes and our noses become more and more senseless.（當(dāng)飛機(jī)爬升時(shí)，氣壓變化，我們的鼻子變得越來越麻木。）可知“當(dāng)飛機(jī)飛到35000英尺高的時(shí)候，鼻子不再有知覺了，就像被蛇咬傷一樣�！� 結(jié)合句意（選項(xiàng)）可知選A。

【4】句意：這也有助于解釋為什么航空公司更喜歡吃咸和辣的食物。根據(jù)上文They help explain why the tomato juice on airplanes tastes far less sour in the air than it does down on the ground.（它們有助于解釋為什么飛機(jī)上的番茄汁在空氣中的酸味遠(yuǎn)低于在地面上的酸味。）可知“這也有助于解釋為什么航空公司更喜歡吃咸和辣的食物�！� 結(jié)合句意（選項(xiàng)）可知選E。

【5】句意：如何解決這個(gè)問題？根據(jù)上文Otherwise, the food would be tasteless. Astronauts also have to do with this problem on their journeys for similar reasons.（否則，食物就沒味道了。宇航員在旅途中也會(huì)遇到類似的問題。）和下文The studies are going on! We are looking forward to any improvements.（研究還在進(jìn)行中！我們期待任何改進(jìn)。）可知是“如何解決這個(gè)問題？” 結(jié)合句意（選項(xiàng)）可知選B。

五選五閱讀主語考查的是學(xué)生的文本語篇分析能力，從而使上下文在語義，語法，結(jié)構(gòu)上完整。技巧及注意事項(xiàng)如下：

判斷挖空所處的位置：一般來講位于句首通常是概括文章的總結(jié)性話語；文章中部通常是轉(zhuǎn)折或者并列關(guān)系；文章末尾通常是總結(jié)段落或全文。

根據(jù)連接詞判斷語境：連接詞諸如but意味著上下文的語義關(guān)系出現(xiàn)轉(zhuǎn)折，遇到此類情況就要弄得上下文說的是什么。而and等并列詞語一般是描述前后兩個(gè)或多個(gè)相似的事情。

根據(jù)作者語氣口吻推斷：該類文章一般情況下主旨明確，有作者自己的態(tài)度傾向，所以做題時(shí)要看出作者持哪一方態(tài)度，不能選擇有悖于作者思想的句子。

A teenage boy couldn’t stand his parents’ family rules, so he left home. He wanted to be famous, but he had a poor education. He couldn’t find a job and had to beg for food on the street.

Years later, his mother died. Though his father was old, he was still looking for his son. He looked in every corner of the city. Wherever he went, he put up a big photo of himself on the wall. On the lower part of the photo, he wrote, “I still love you, my dearest son. Please come back home!”

One day, the son saw one of the photos on the wall. The face on the photo was familiar to him. “Is that my father?” He moved closer and read the words, “I still love you...” Tears ran down his face. He made up his mind to go back and see his dad.

It was early morning when he got home. He knocked on the door. Nobody answered, although the door did open. He rushed into his father’s bedroom. His father was sleeping. The boy woke his father up. “It’s me! Your son is back home!” The father and the son held each other with tears in their eyes. The son asked, “Why is the door unlocked? A thief could get in.” The father answered in a soft voice, “The door has never been locked since you left.”

【題目】Would you like to improve yourself？ Would you like to be a better person？ Good news! Here we've got some tips for you．

Tip 1Be Kind

Remember to be kind to yourself． You can do simple things to take care of yourself， like getting enough sleep to make yourself energetic． If you don't do like that， you will not bring anything good to anyone else． When you decide to show more kindness to yourself and to others， life changes quickly in a better way．

Tip 2Be Encouraging

It's amazing what a kind word or touch can do． When I was a kid， I went to a lot of schools． It always made me scared， and I was very nervous and unsure of myself． One time， a teacher touched my head and said， smiling， "Don't worry﹣you'll have a good time with us in this classroom．" I still remember my teacher's words．

All of us may come across some trouble in our life， and a bit of encouragement can be remembered for years．

Tip 3

When my sister and I were kids， my mum didn't have a car and our school was a 30﹣minute walk． Our neighbor offered to drive us to school when she dropped her son off， and that saved my mother a lot of time． Giving help to others can bring you happiness．

When thinking about how to become a better person， remember that small changes are also important． But "be kind to yourself" comes first． As the old saying goes， "You can't pour from an empty cup．" So in order to be a person who can give more love to this world， you have to fall in love with yourself first．

【1】The underlined word "It" in Tip 2refers to （指代） ．

【題目】Don’t be too surprised if you see a car going down the road without a driver in Beijing these days. It might be one of Baidu’s self-driving cars.

Self-driving cars have been in development since 2010, when Google announced that it was making such cars. Since then,companies like Tesla, Uber and Baidu have been working to produce and test their own self-driving cars.

Self-driving cars are expected to change the way we get around. They are safer and more environmentally friendly than usual cars. They can remove the stress of driving and allow disabled or blind people to get around more easily.

But self-driving cars have their own flaws (缺陷)as well. In one test, researchers pointed a laser pointer (激光棒)at the car’s sensors (傳感器)while it was moving. The car mistakenly thought that the laser beam(激光束）was in its way and slowed down or changed direction. Flaws like this could be used by people to trick self-driving cars.

The software (軟件)that is used to direct the cars may not be safe enough. It may crash (崩潰),When we use our computers or smart phones, they sometimes crash without any reason. But if this happened to a self-driving car, the results could be deadly. Improvements to the software could be a way to deal with this problem.

Anyway, whether you like it or not, it’s only a matter of time before they’ll become more affordable and popular on our roads.

【1】 was the first company to develop self-driving cars?

A. Google.B. TelsaC. Uber.D. Baidu.

【2】What does Paragraph 3 mainly talk about?

A. Solutions for disabled people.B. Tips for riding in self-driving cars.

C. Reasons for testing self-driving cars.D. Advantages of self-driving cars.

【3】When sensing an obstacle(障礙物）in the road，self-driving cars will .

A. attack it with a laser pointerB. slow down or change direction

C. crash into it to get past itD. stop and move around it

【4】Which of the following statements is WRONG according to the passage?

A. Self-driving cars free people from the stress of driving.

B. Self-driving cars can reduce traffic accidents.

C. Researchers have solved the problems self-driving cars have.

D. The software of the self-driving cars needs improvements.

【5】What’s the writer’s opinion about the self-driving cars?

A. They are more dangerous.B. They’ll be well developed in the future.
