試題詳情
You've probably heard it suggested that you need to move more throughout the day，and as a general rule of thumb，that "more" is often defined as around 10，000 steps.With many Americans tracking their steps via new fitness-tracking wearables，or even just by carrying their phone，more and more people use the 10，000-step rule as their marker for healthy living.Dr.Dreg Hager，professor of computer science at Johns Hopkins，decided to take a closer look at that 10，000-step rule，and he found that using it as a standard may be doing more harm than good for many.
"It turns out that in 1960 in Japan they figured out that the average Japanese man，when he walked 10，000 steps a day burned something like 3，000 calories and that is what they thought the average person should consume so they picked 10，000 steps as a number." Hager said.
According to Hager，asking everyone to shoot for 10，000 steps each day could be harmful to the elderly or those with medical conditions，making it unwise for them to jump into that level of exercise，even if it's walking.The bottom line is that 10，000 steps may be too many for some and too few for otjye.airs.He also noted that those with shorter legs have an easier time hitting the 10，000-step goal because they have to take more steps than people with longer legs to cover the distance.It seems that 10，000 steps may be suitable for the latter.
A more recent study focused on older women and how many steps can help maintain good health and promote longevity （長(zhǎng)壽）.The study included nearly 17，000 women with an average age of 72.Researchers found that women who took 4，400 steps per day were about 40% less likely to die during a follow-up period of just over four years：Interestingly，women in the study who walked more than 7，500 steps each day got no extra boost in longevity.

1．British children's writer Roald Dahl ate chocolates and sweets "pretty much every mealtime"，remembers daughter Ophelia Dahl．
After dinner，whether dining alone or entertaining guests，Dahl would pass around a little red plastic box full of Mars Bars，Milky Ways，Maltesers，Kit Kats and much more．
He knew the history of all the sweets and could tell you exactly when they were invented．1937 was a big year when Kit Kats （his favorite），Rolos and Smarties （his dog，chopper's favorite） were invented．He wrote a history of chocolate，lecturing schoolchildren to commit such dates to memory（熟記），such as 1928 when "Cadbury's Fruit and Nut Bar popped up on the scene"，saying． "Don't bother with the Kings and Queens of England．All of you should learn these dates instead．Perhaps the Headmistress（女校長(zhǎng)）will see from now on that it becomes part of the major teaching in this school．"
According to Dahl，the Golden Years of Chocolate were 1930-1937．In 1930，Roald Dahl was 14 years old．He was a student at Repton，a famous boys' boarding school in England．It was a tough environment：those in authority were more interested in controlling than educating the students．
Ironically（諷刺地），it was at this difficult period that chocolate became Dahl's passion．Near Repton was a Cadbury chocolate factory．Every so often，Cadbury would send each schoolboy a sampler（樣品）box of new chocolates to taste and grade．They were using the students---"the greatest chocolate bar experts in the world to test out their new inventions．
This was when Dahl's imagination took flight．He pictured factories with inventing rooms with pots of chocolate and fudge（軟糖）and "all sorts of other delicious fillings bubbling away on the stoves"．
"It was lovely dreaming those dreams…when I was looking for a plot for my second book for children．I remembered those little cardboard boxes（紙盒）and the newly invented chocolates inside them，and I began to write a book called Charlie and the Chocolate Factory．"
For the record，Roald Dahl did not like chocolate cake or chocolate ice cream．He said， "I prefer my chocolate straight．"
（1）What's the purpose of the first paragraph？
A．To introduce the main topic---Roald Dahl．

C．He used to lecture schoolchildren of a boys' boarding school．
D．He only wrote some books related to the history of chocolate．
（3）What happened during the Golden Years of Chocolate？

2．Recently，a film star has been giving away free books on the London Underground．If you're a bookworm，a Harry Potter fan and a London Underground user，then it's been an exciting month for you．
Emma Watson，who starred in films based on the novels about a fictional schoolboy wizard，has been hiding books on the Tube for passengers to read through．
It's part of he Book On The Underground movement，which has a simple aim：to get more people burying themselves in literature．Books are left on trains for passengers to pick up，dip into and then leave for another lucky reader to skim．
The movement started in 2012 and drops off about 150 books a week in stations across London．Talking about Watson's participation in the project，the manager of Books On The Under ground，Cornelia Oxley，said， "The reaction has been great．It must be a mixture of how much everyone admires Emma，and how exciting it is to find something as wonderful as a new book on your journey．"
The 100 or so books Watson left for passengers to read were even more special because she left a hand-written inscription（題詞）．The books were Kaya Angelou's Mom & Me & Mom．
One person who discovered a copy of the book on the Tube said she felt like the character Charlie Bucket - a boy who finds a golden ticket to the world's greatest chocolate factory - in the Roald Dahl's classic，Charlie and the Chocolate Factory Watson became a UN Women Goodwill Ambassador in the summer of 2014 and has since started reading as many books and essays on equality and feminism（饑荒） as possible．She has also started her own book club．
So．Why not take a leaf out of Emma Watson's book and leave a copy of your favorite book on a train？It could make a stranger's life richer．

3．It can be really hard to learn a new language．I had always enjoyed learning languages in school，but only recently did I start learning German．I found that I could understand and learn individual words easily，but when it came to literature，I really struggled．That was when my tutor at university suggested reading some children's books printed in the target language．
At first，I felt a bit silly going on a hunt for a book designed for someone half my age，but then I realised that everyone has to start somewhere．As children，we are given these basic texts to familiarise our brains with certain vocabulary and writing structures，and from there，we can learn and develop．I started with books which are taught to us as children in the UK．I managed to find Oliver Twist by Charles Dickens and James and the Giant Peach by Roald Dahl．
The beauty of reading books that were introduced to you as a child is that you are already familiar with the plot．Therefore you can work out some words with your knowledge of the story．At first，I used to read with the book in one hand and a dictionary in the other，but this did not work well．The method I would recommend is to read a chapter first and at the end of that chapter，highlight the new words and then look up the definitions．If you can wait a bit before using a dictionary，you may be surprised what you can understand merely from the context．Additionally，a lot of children's books have pictures which may give you a clue as to what or to whom the passage is referring．
If you can find a translation of the books you have read as a child，I would strongly advise reading those if you are a complete beginner．However，if you feel a bit more confident reading in English，I would personally recommend the series of 'Harry Potter' books by J．K．Rowling or any of the Roald Dahl children's books．
（1）What makes it hard for the author to learn German？
A．The author had a poor memory．
B．The author had no interest in it．
C．The author had no one to ask for help．
D．The author couldn't read books fluently．
（2）What did the author think of reading children's books in the target language at first？
A．Interesting．
B．Stupid．
C．Helpful．
D．Boring．
（3）What does the author try to express mainly in Paragraph 3？
A．How to deal with new words while reading．
B．Why it is helpful to read children's book at first．
C．How to choose a proper book to match your level．
D．How to form the habit of reading in the target language．
（4）Why does the author write this text？
A．To give tips on how to learn a new language．
B．To persuade the readers to learn a new language．
C．To stress the importance of reading in language learning．
D．To share the author's stories of learning a new language．發(fā)布：2025/1/30 8:0:1組卷：5引用：1難度：0.5
