A.Try planks (平板支撑) for full body toning (身体紧实)

B.If you want an added challenge, hold weights while you squat.

C.Do push-ups to tone your upper body

D.Then bring your left knee to your chest

E.If that is too difficult, lower yourself onto your elbows

5B

【解析】

这是一篇说明文。锻炼有很多好处。文章介绍了一些让你开始锻炼的好主意。

1分析句子结构:___1___, when you start feeling and looking just as you desire.根据后半句when you start feeling and looking just as you desire.“在这时候你开始按照自己的愿望去感受和观察。”这后半句应该是一个when引导的时间状语从句,由此可知,FThe hard work will pay off big time(努力工作会有丰厚的回报)切题。该项中time作先行词,在后面的定语从句中作时间状语。故选F

2根据Run in place中的Start by running in place for five minutes.“从原地跑五分钟开始。”承接上文,GThen, try to run in place for ten minutes(然后,试着在原地跑十分钟)切题。该项中的then将上下文连在一起,故选G

3分析句子结构___3___, keeping your arms in place.可知,该空应该是一个完整句子,只能在A/C/D中选择。根据后半句keeping your arms in place.“保持手臂不动”。承接后半句,DThen bring your left knee to your chest(然后将左膝放在胸前)切题。故选D

4该空是小标题,应该用短小精悍的祈使句。根据下句“以平板支撑的姿势开始。”由此可知,CDo push-ups to tone your upper body(做俯卧撑来锻炼上半身)切题。故选C

5根据上文提示“坚持做三组,每组20组。”承接上文,BIf you want an added challenge, hold weights while you squat.(如果你想增加一个挑战,在你蹲下的时候保持负重)切题。故选B

【题目】 Young children often “read” picture books. They’re attracted by the colorful scenery and the realistic characters that contribute to fascinating plots.

Unfortunately, some children can’t use these resources, even if they do know how to read. Take three-year old Elodie Bateson, for example. Elodie was born with under-developed eyes and has retinal detachments(视网膜脱落),making her visually impaired.

It is because of people like Elodie that Tom Yeh, head of the Tactile Picture Books Project, has started printing 3D books, so they can feel the illustrations in picture books.

The first book Tom Yeh printed was Goodnight Moon, a popular children’s book about a rabbit going to sleep and wishing good night to his surroundings. In the 3D version of this book children can feel each thing that the rabbit says good night to, whether it is a cow jumping over the moon, a balloon, or a dollhouse.

Generally, when children grow older, they read by using Braille, a language that was invented by Louis Braille in 1824. It uses different patterns of raised dots representing different letters. Readers can then feel the dots and mentally translate the patterns they feel into words. The only problem is that many blind children do not start learning Braille until they are about six years old.

Another reason why 3D printed books are such a valuable resource is that children don’t have to know how to read to understand them. However, without these, visually impaired kids are losing six developmental years vital to their growth since they can ’t take advantage of picture books.

When 3D picture books are printed, plastic is layered(分层放置)repeatedly over a single shape: the shape of the illustration. These raised pictures created through layered plastic serve as substitutes for the Braille letters that little children have no knowledge of.

1What does the underlined word “impaired” in paragraph 2 mean

A.Unmatched.B.Disappeared.

C.Defeated.D.Damaged.

2What can we know about Braille from Paragraph 5

A.The blind at any age can read by using Braille.

B.Most people can translate Braille into words.

C.Blind kids begin learning Braille at about six years old.

D.Braille uses similar patterns of raised dots to stand for different letters.

3We can know that the illustrations in 3D books are raised ______ .

A.dotsB.pictures

C.lettersD.plastic

4What is the aim of the Tactile Picture Books Project

A.To teach the blind children Braille.

B.To encourage kids to read books.

C.To cure visually impaired children.

D.To help the blind children read picture books.
