【題目】 _________ the task on time, he was fired by the boss.

A. Not completed B. Not having completed

C. Not have completed D. Not being completed

【答案】B

【解析】

試題分析：考查非謂語動詞。句中邏輯主語為he，與complete之間為主動關(guān)系，且具有時間的先后性，故用having done。句意：沒有準(zhǔn)時完成任務(wù)，他被老板開除了。故B正確。

【題目】A Japanese company is developing a pair of smart glasses that can help those with visual or comprehension problems to read written text more easily. Called the Oton Glass, the glasses are meant to translate text into sound using two cameras and an earpiece, both fitted to its frame.

Half of the lens (鏡片) is a mirror that reflects the wearer’s eyes back to the first camera, which tracks eye movement. The other camera captures the text. Wearers use the glasses by staring at the text they can’t read and blinking (眨眼) to trigger the glasses. Then the captured words are sent to a cloud system, which processes the text and turns it into sound played through the earpiece. If the system is unable to identify the words, the images are sent to a remote worker who can deal with them.

The Oton Glass lead designer, Keisuke Shimakage, started working on the glasses in 2012 to aid his father, who had developed dyslexia, a condition that makes it difficult for someone to read and spell. While his father eventually recovered, Shimakage continued his development in order to help others with the disorder.

Currently, the Oton Glass is seeking funding. Backers can get a pair of the glasses for 5,000 yen (roughly $47).

Smart glasses aren’t a new concept, but it’s difficult to point to any single pair of smart glasses that people have reviewed favorably. It could, perhaps, be that previous products tried to do too much, or were too expensive. That’s why Intel’s Vaunt smart glasses stripped out some features, like its camera, LCD screen, and speakers. The Oton Glass is for a very specific audience, and its relatively low price could make it more appealing to those who want an affordable way to understand the text around them.

【1】What was Keisuke’s original purpose in designing the Oton Glass?

A. To treat his father’s disease.

B. To translate text into sound.

C. To assist his father to read.

D. To make written text easier to read.

【2】What is the right order how the Oton Glass works?

a. The camera captures the words.

b. The wearer stares at the text.

c. The wearer hears the sound via the earpiece.

d. The cloud system turns the text into sound.

e. The wearer blinks to get the glasses working.

A. a, b, e, c, d B. e, b, c, d, a

C. b, d, a, e, c D. b, e, a, d, c

【3】The underlined part “stripped out” in the last paragraph can be replaced by ________.

A. improved B. removed

C. increased D. invented

【4】What is the last paragraph mainly about?

A. The advantages of the Oton Glass.

B. The characteristics of smart glasses.

C. Consumers’ evaluation of the Oton Glass.

D. The target audiences of various smart glasses.
