【解析】
本文主要講了什么是靜電,以及介紹了幾種免遭靜電的方法。
【1】根據(jù)上文Static shock(靜電)happens whenever two different materials come into contact with one another. 每當(dāng)兩種不同的材料相互接觸時(shí),就會發(fā)生靜態(tài)?芍恼乱婚_頭先介紹靜電的產(chǎn)生,由此可推斷出接下來講靜電對人的影響。所以C.While relatively harmless, static shocks can be annoying and even painful. 雖然相對無害,但靜態(tài)沖擊可能是煩人的,甚至是痛苦的。符合上下文邏輯,故選C。
【2】根據(jù)上文Certain types of shoes can reduce the risk of shock. 某些類型的鞋子可以減少靜電的風(fēng)險(xiǎn)?芍呗芬矔a(chǎn)生靜電,所以A. People can build up static shock when they walk around. 人們走動時(shí)會產(chǎn)生靜電沖擊。符合上下文邏輯,故選A。
【3】根據(jù)Wear leather-soled(皮革底)shoes over rubber-soled (橡膠底)shoes when shopping, as the leather-soled shoes are less likely to produce static shock. 購物時(shí)要穿上皮革底的皮鞋,不要穿橡膠鞋,因?yàn)槠じ镄惶赡墚a(chǎn)生靜電沖擊。所以A.Using less such materials can reduce the risk of static shock. 少使用這類材料可以降低靜電沖擊的風(fēng)險(xiǎn)。符合上下文邏輯,故選E。
【4】根據(jù)上文Humidify your home給你的家增濕,由此可以推斷出靜電沖擊更有可能出現(xiàn)在干燥的環(huán)境中。所以D. Static shocks are more likely to appear in dry environments. 符合上下文邏輯,故選D。
【5】根據(jù)上文You can do something useful to avoid static shock. When pushing a cart(推車), hold onto something metal like your house keys. 你可以做一些有用的事情來避免靜態(tài)沖擊。推一輛手推車時(shí),拿一些金屬的東西,比如你的房子鑰匙?梢酝茢喑鲎呗窌r(shí)所積累的任何能量可以以靜電方式釋放出來,所以F. This give off any energy you build up while walking before you touch anything with your hands. 在你用手觸摸任何東西之前,這會釋放出你走路時(shí)所積累的任何能量。符合上下文邏輯,故選F。

【題目】 Have you ever stayed deep underground in a cave? You have no food and the oxygen(氧氣) is running out. You're not even sure if anyone knows you're down there.
A soccer team of 12 young Thai boys, as well as their coach, had to go through this experience this summer. They became trapped in a cave in Thailand on June 23, spending 18 days inside until they were saved by an international team of divers(潛水員). After hearing the news that a former Thai Navy SEAL(海 軍海豹突擊隊(duì)員)died while trying to save these kids, my friends and I talked about the situation and felt as if there might be no way to get the children out.
But we held out hope anyway. We refused to give up hope for these kids, even when the situation seemed quite dark. We were rewarded(獎(jiǎng)勵(lì))for our hope when they were finally saved.
It can be hard to hold out hope in dark times. Every day, we read or hear about the terrible things that happen in the world. This makes it hard for us to stay positive. Some people go through their lives thinking that the worst is always just around the corner.
However, I believe that it's especially important to stay positive during difficult times. This is the best way to deal with the challenges that we face in life. As people often say: there is always a light at the end of the tunnel(隧道).
【1】How many people were trapped in a cave in Thailand on June 23?
A.12.B.13.C.18.D.23.
【2】What does the underlined word “trapped” in Paragraph 3 mean?
A.捕獲的B.收集的C.受困的D.失望的

A.not all of the kids were saved
B.a man died when he tried to save the kids

D.the Thai Navy SEAL were rewarded by the government
【4】According to the passage, when we face challenges, we should _______.
a. hold out hope b. stay positive c. give up d. wait for help

【題目】 What are some of the biggest scientific discoveries in the history of humans? How have they changed our lives? Are all the scientists born with creativity?
There was once a famous scientist who made several important discoveries. Once he was asked how he was able to be so creative. He replied that it all came from an experience he had with his mother at the age of 2. He was trying to take a bottle of milk out of the fridge. But the bottle was too slippery and he dropped it. The kitchen was covered in milk.
When his mother came into the kitchen,instead of shouting at him or punishing him,she said,"Robert,what a great and wonderful mess you have made!I have never seen such a huge puddle(水坑)of milk. Would you like to play in the milk for a few minutes before we clean it up?"
So he did. After a few minutes,they cleaned it up together. Then his mother said,"This was a failed experiment(實(shí)驗(yàn))in how to carry a big bottle of milk with two small hands. Let's go out in the backyard and fill the bottle with water and see if you can find a way to carry it without dropping it.”
The little boy learned that if he held the bottle at the top near the mouth with both hands,he could carry it without dropping it. What a wonderful lesson!
The scientist then added that it was at that moment that he knew he didn't need to be afraid to make mistakes. He learned that mistakes are just chances to learn something new which is after all, what scientific experiments are all about.

When the car“ sees ”an obstacle(障礙物), it sends the information to a data center and receives instructions. However, it takes time to send and receive information. With this kind of lag, the cars might crash because they don’t receive instructions in time. With 5G, this lag will be great lowered , making the cars safer, according to CNN.
5G could also be used to power the Internet of Things(IoT 物聯(lián)網(wǎng)). This refers to a large online network that connects all things and people. Fast Internet speeds will be the key to develop this technology.
The IoT could be used in a lot of ways. For example, with IoT, your refrigerator could automatically place an order online for eggs when it finds that there are no eggs left inside.
