高三英语单项填空中等难度题查看答案及解析

Like distance runners on a measured course，all of us will move through time in a roughly predictable pattern．

In the first stage of our lives，we develop and grow, reaching toward the top of physical vitality(活力)．

After we grow up，however, the body begins a process of gradually wearing out．

A new awareness of physical fitness may help lengthen our years of health and vitality，yet nothing we do will work to stop the unavoidable force of aging．

Most of the changes of aging take place deep inside the body．The lungs become less able to take in oxygen．Powerful muscles gradually lose their strength．The heart loses power and pumps less blood．Bones grow easier to break．

Finally, we meet a stress，a stress that is greater than our physical resistance．Often，it is only a minor accident or chance infection(a disease caused by virus)，but this time，it brings life to an end．

In 1932，a classic experiment nearly doubled the lifetime of rats，simply by cutting back the calories in their diet The reason for the effect was then unknown．

Today, at the University of California at Berkley, Dr．Paul Seagle has also greatly lengthened the normal lifetime of rats．The result was achieved through a special protein limited diet，which had a great effect on the chemistry of the brain．Seagle showed that within the brain，specific chemicals control many of the signals that influence aging．By changing that chemical balance，the clock of aging can be reset．

For the first time, the mystery of why we age is being seriously challenged．Scientists in many fields are now making striking and far-reaching discoveries．

An average lifetime lasts 75 years，yet in each of us lies a potential for a longer life．If we could keep the vitality and resistance to disease that we have at age twenty, we would live for 800 years．

1.What does the underlined word “it” refer to?

A．By keeping their physical fitness．          B．By cutting the calories in their diet．

C．By resetting their clock of aging．           D．By limiting the protein in their diet．

5.What is probably the best title for the article?

高三英语单项填空简单题查看答案及解析

Last year, the Bureau of Labor Statistics reported that 55 million people in the U. S. are “gig workers" which is more than 35 percent of the U. S. workforce. That number is projected to jump to 43 percent by 2020.

People are drawn to gig work（零工）because it brings in a little extra income without a major time commitment. And recent technologies like Skype, Slack, and Dropbox have made the gig life a reality, giving you maximum freedom, an ideal work-life balance, and the chance to pursue your passions.

If you're thinking of joining the gig economy, it's never been easier. One of the great things about the gig economy is that you don't have a boss breathing down your neck. As a freelancer, you no longer have to cater to a company culture or work schedule that might cause physical or emotional stress. Instead, you get to choose the type of work you do and who you work with. But this degree of freedom requires a corresponding amount of discipline. With no boss to make sure you're on task, it's all on you.

A lot of gig workers start their careers by hopping on a project because the employer is desperate and in need of help. On the employer's end, it's tough to take on people for higher management positions when the pool of talent is full of gig workers who haven't been given an opportunity to improve their skills. Businesses have to evolve to learn how to account for an influx（(涌入）of temporary workers. It is harder for gig workers to become skilled and get promoted.

The workforce is becoming more advanced and educated by the day. You have to keep learning and keep up with industry trends to maintain a competitive edge. This is true even for people in traditional office settings, but it's critical if you're your own boss.

1.What made the gig life a reality?

A.Greater work-life balance. B.New technologies.

C.A little extra money. D.Maximum freedom.

2.What does the underlined phrase “breathing down your neck” in Paragraph 3 mean?

A.Making you unable to breathe freely.

B.Standing very close behind you.

C.Threatening you by saying something.

D.Monitoring you closely.

3.What can we infer from the last but one paragraph?

A.Employers should invest in training the temporary workers.

B.Gig workers start their jobs out of passion.

C.It's hard for employers to employ people for higher positions.

D.It's hard for gig workers to develop skills.

4.Which of the following can be the best title for the text?

A.The Strengths and Weaknesses of the Gig Economy

B.The Challenges of the Gig Economy

C.The Increase of the Gig Economy

D.The Reason for the Gig Economy
