【題目】Next time you’re planning to go out for a relaxing walk with your MP3 player, be sure to check the weather forecast first. Summer is the prime time for lightning strikes, a fact that Jason Bunch, a teen from Castle Rock, Colo, learned in a hard way. A couple of summers ago, he was mowing (割草) grass while listening to some Metallica on his iPod. Although there wasn’t any rain falling on Bunch, he did hear distant thunder. Bunch was then struck by lightning, which seemed to travel through his music player, blowing out his eardrums and leaving him with burns where the device and its power lines were close to his body.

Devices such as MP3 players don’t attract lightning, says Dr. Mary Ann Cooper, an emergency room physician at the University of Illinois Medical Center in Chicago. However, they may change the pathway that lightning’s energy follows in the human body. Lightning that might have passed rather harmlessly over the skin may react differently to the metal of these devices and cause damage.

Rather than leaving your tunes at home, your best bet is watching out for lightning before it hits. Though people have been injured while using MP3 players in storms, Cooper says, “The devices’ main task is keeping you from paying attention to thunder and the sky.” If you’re caught in a storm, seek shelter.

【1】When does lightning happen most?

A. Winter. B. Fall. C. Summer. D. Spring.

【2】What was the effect of this lightning strike on Jason Bunch?

A. The lightning burned Bunch and blew out his eardrums.

B. The lightning passed harmlessly over Bunch’s skin.

C. Bunch fell to the ground and couldn’t move his upper body.

D. Bunch was fine, but his iPod was burned by the lightning.

【3】What can you conclude about the safety of using MP3 players during a storm?

A. MP3 players are desperately unsafe to use during a storm.

B. IPods are safe to use during a storm, but other MP3 players are not.

C. MP3 players increase your safety during a storm by directing lightning toward the ground.

D. MP3 players become unsafe to use if they keep you from paying attention during a storm.

【4】The primary purpose of this text is .

A. to describe the joy that Jason Bunch felt after he survived a lightning strike

B. to inform the risks of wearing an MP3 player during lightning strikes

C. to tell a lightning emergency Jason Bunch met with

D. to show that MP3 players are so popular among teenagers

【題目】Directions: After reading the passage below, fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.

There's a widely-accepted line of thinking, especially in 2019 that says the people and things we love will eventually let us down.

It was with this cynical mentality 【2】 I approached the second season of 2018’s breakout hit Killing Eve. How could a series that was so well written, so well acted, and so fiercely addictive in freshman season possibly【3】 (maintain) the same level of quality in Season 2, especially since Phoebe Waller-Bridge,【4】developed the series for TV and wrote four of the first season’s eight episodes, wasn't involved in the writing of the second?

It's just that 【9】happens to be an assasin (暗殺者) and the other a spy.

【題目】 My grandmother grew up in a world different from me. She experienced many things in her long life.

Though she never told stories, her stories were in the way she ate — she savored (品味) her food, cherished (珍惜) it. Often she would be the first to sit at the dinner table, and the last to leave. Food had been really scarce (缺乏) when she grew up.

Her stories were in the way she handed me lucky money. From a young age, my grandmother was brought up to understand the importance of hard work and the necessary of saving. Every Chinese New Year, I would be handed, or sent, a small red envelope that contained money, but never more than twenty dollars. When I was young , I didn’t understand why my grandmother gave me such a small amount of money. As I grew older, I realized that she wasn’t teaching me about money, but about tradition and hard work and family. The money was insignificant. I would probably spend it on any toy that I would lose soon after; it was the meaning behind her gift that mattered. It was her saying, “ I love you; I am your family and I want you to work hard as your family has before you.”

My grandmother’s stories were lessons. But they were never told in words. From the time that I was very young, up until she could barely remember my name, I remember her calling me “good girl”. Those two little words, in the course of my growing up, were a constant reminder that I was still so young, with still so far to go.

Now my grandmother is gone, but I see her every day. I see her in the women around me and in the mirror. She lives with me, inside me, and in the legacies(遺產(chǎn))that I will create. And I know she would be proud.

【1】The Author’s grandmother spent so much time eating at the table because ________.

A.she had no teethB.she had nothing to do

C.she was preparing to clear the tableD.she really wanted to enjoy the food

【2】What did the author learn from the way her grandmother gave her lucky money?

A.Her grandmother didn’t have much money.

B.Her grandmother preferred boys to girls.

C.It was a shame to accept others’ money.

D.It was important for her to work hard.

【3】What did the author realize hearing her grandmother call her “good girl” ?

A.She was really a good girl.

B.She needed to continually improve herself.

C.She should be proud of her manners and behaviors.

D.She was always a good girl in her grandmother’s eyes.

【4】What can we know about the author’s grandmother after reading the passage?

A.She loved telling stories.

B.She had never worked in her life.

C.She set a great example for the author.

D.She was a mean woman with old-fashioned values.

【題目】Standing desks have become common across Silicon Valley, offering health benefits to those willing to work on their feet. However, due to their high price, they have failed to catch on until now. Recently, Ikea has brought out Bekant convertible（可改變的）standing desk that can become a normal desk at the touch of a button. The $500 adjustable desk can transform from a standard desk to a standing one, and Ikea hopes it could make the standing desk mainstream.

Experts say that changing from a seated to a standing desk can improve productivity. Similar desks have become a common sight at tech firms such as Google, where some employees have even installed treadmill (跑步機(jī))and bicycle desks.

The desk is not the first “convertible” on the market. As early as 2013, Stir Kinect brought out an adjustable desk. The $3,890 Stir Kinect desk has a motor to raise and lower itself, converting it into a standing desk or a traditional desk. The desk can even be programmed to move up and down slightly, making it appear to take a gentle breath to remind the user to change their position. To move between sitting and standing positions, owners simply double tap on the screen. The desk can learn the user’s preferences over time and suggest the best seating position.

The Stir Kinect desk was created by a team of ex-Apple and Disney engineers. It has a built-in touch screen to control and track movement, and can tell users exactly how many calories they burn by standing during their working day. It also has devices containing power points and USB ports for charging phones, to keep cables hidden.

“Ikea’s height adjustable desk is great for opening up the lower end of the market, ’’ said JP Labrosse, founder and CEO of Stir.

【1】What is the text mainly about?

A. Ikea has brought out an adjustable standing desk.

B. Silicon Valley offered health benefits to officials.

C. Google formed their tech firms to design bicycle desks.

D. The Stir Kinect desk will become mainstream in the market：

【2】 Which of the following is TRUE according to the text?

A. Before Bekant desk, similar adjustable desks have been widely used.

B. The seated desks will take the place of the standing desks in the future.

C. Compared to the Stir Kinect desk, the Bekant desk is much cheaper.

D. The adjustable desks were designed by the Apple and Disney Company.

【3】The Stir Kinect desk______.

A. can breathe in and breathe out by pressing the button once.

B. can charge phones by using a device containing power point.

C. can tell you how many calories you need for a walk

D. can advise you to do more exercise at a proper time
