Many jobs must be done with two people. One person takes the lead. The other helps. So it is with the human body. Much of our body depends on the cooperation between substances. When they work together, chemical reactions take place smoothly. Body systems are kept in balance.
Some of the most important helpers in the job of good health are the substances we call vitamins. The word “vitamin” dates back to Polish scientist Casimir Funk in 1912. He was studying a substance in rice. Funk believed the substance belonged to a group of chemicals known as amines (胺类). He added the Latin word “vita”, meaning life. So he called the substance a “vitamine”—an amine necessary for life.
Other studies found that not all vitamins were amines. So the name was shortened to vitamin. But Funk was correct in recognizing their importance.
Scientists have discovered 14 kinds of vitamins. They say vitamins help to carry out chemicals changes within cells. If we do not get enough of the vitamins, we are at risk of developing a number of diseases. This brings us back to James Lind of Scotland. In the 1740s, Lind was a doctor for the British Navy. He was investigating a problem that had existed in the Navy for many years.
The problem was the disease scurvy(坏血病). The sailors were weak from bleeding inside their bodies. Even the smallest wound would not heal. Doctor Lind thought the sailors were getting sick because they failed to eat some kinds of foods when they were at sea for many months.
Doctor Lind separated twelve sailors who had scurvy into two groups. He gave each group different foods to eat. One group got oranges and lemons. The other did not. The men who ate the fruit began to improve within seven days. The other men got weaker.
However, which foods should be eaten to keep us healthy? Let us look at some important vitamins for these answers.
1.Why was the name “vitamine” shortened to “vitamin”?
A. Because Funk was totally wrong.
B.Because few vitamins were amines.
C. Because there were new findings.
D. Because the latter was easy to remember.
2.The underlined word “This” in the fourth paragraph probably refers to that _______.
A. people tend to develop many diseases
B. lack of the vitamins causes disease
C. vitamins help chemical changes within cells
D. it is common for people to get no enough vitamins
3.Doctor Lind proved eating fruits can prevent scurvy by means of _______.
A. comparing B. analyzing C. surveying D. questioning
4.What is the main topic of the passage?
A. Food to keep us healthy.
B. The benefits of vitamins.

D. Facts about vitamins.

Job sharing refers to the situation in which two people divide the responsibility of one full-time job. The people willingly act as part-time workers, enough hours between them to fulfill the duties of a full-time worker. If they each work half the job, for example, they each receive 50 percent of the job’s wages, its holidays and its other benefits.
Job sharing differs from conventional(常规的) part-time work in that it occurs mainly in the more highly skilled and professional areas, which require higher levels of responsibility and employee commitment.
Job sharing should not be confused with the term work sharing, which refers to increasing the number of jobs by reducing the number of hours of each existing job, thus offering more positions to the growing number of unemployed people. Job sharing by contrast, is not designed to address the growing number of unemployed people. Job sharing, by contrast, is not designed to address unemployment problems; its focus, rather is to provide well-paid work for skilled workers and professionals who want more free time for other activities.
As would be expected, most job sharers are women. A survey carried out in 1988 by Britain’s Equal Opportunities Commission showed that 78 per cent of sharers were female, the majority of whom were between 20 and 40 years of age. Subsequent studies have come up with similar results. Many of these women were re-entering the job market after having had children, but they chose not to seek part-time work because it would have meant lower status. Job sharing also offered an acceptable shift back into full-time work after a long absence.
The necessity of close cooperation when sharing a job with another person makes the actual work quite different from conventional one-position jobs. However, to ensure a greater chance that the partnership will succeed, each person needs to know the strengths, weaknesses and preferences of his or her partner before applying for a position. Moreover, there must be a fair division of both routine tasks and interesting ones. In sum, for a position to be job-shared well, the two individuals must be well matched and must treat each other as equals.
1.In what way is work sharing different from job sharing?
A.Work sharing requires more working hours. |
B.Work sharing is aimed at creating more jobs. |
C.Work sharing provides a more satisfactory salary. |
D.Work sharing depends on the employer’s decision. |
2.According to paragraph4, young mothers preferred job sharing to conventional part-time work mainly because______.
A.they sought higher social status |
B.they were over ideal working ages |
C.they had difficulty finding full-time jobs |
D.they had to take care of both work and family |
3.In job sharing the partners should ______.
A.enjoy equal social status |
B.have similar work experience |
C.keep in touch with each other |
D.know each other very well |

Upskilling is the future—but it must work for everyone
Automation and job replacement will be one of the most significant challenges for the global economy of the coming decades. A 2017 Mckinsey report established that 375 million workers will need to switch occupational categories by 2030. The World Economic Forum suggests that by 2022, automation will replace 75 million jobs globally—but create 133 million new ones.
Research into the likelihood that a job will be impacted by digitization has largely focused on the “automatability” of the role and the following economic regional and political effects of this. What this research doesn’t take into account is something more important for the millions of taxi drivers and retail workers across the globe: their likelihood of being able to change to another job that isn’t automatable. Recent research suggests that the answer to this may be that the skills that enable workers to move up the ladder to more complex roles within their current areas might be less important than broader skills that will enable workers to change across divisions.
In July, Amazon announced that it would spend $700 million retraining around 30% of its 300,000 US workforce. While praiseworthy, it will be interesting to see the outcome. In the UK, the National Retraining Scheme has largely been led by employers, meaning that those on zero-hours contracts and part-time workers—often low-skilled—will miss out. Governance will be a crucial element of ensuring that such schemes focus on individuals and life-long learning, rather than upskilling workers into roles that will soon also face automation.
According to the Mckinsey report, “growing awareness of the scale of the task ahead has yet to translate into action. Public spending on labour-force training and support has fallen for years in most member countries of the Organisation for Economic Co-Operation and Development,” which impacts more than just the low-skilled and poorly compensated.
The global impact of automation is also put into relief by research demonstrating that, between 1988 and 2015, income inequality increased throughout the world. Billions of people do not have the essentials of life as defined by the UN Sustainable Development goals.
Alongside climate change, automation is arguably tech’s biggest challenge. As with globalization, governments and employers—and us workers—ignore its potential consequences at risk to ourselves.
1.It can be known from Paragraph 2 that .
A.recent research has found ways to face automation
B.broad skills are of great significance in changing jobs
C.regional economy can affect the automatability of a job
D.it is even harder for workers to move up the social ladder
2.What is the author’s attitude towards retraining programs?
A.Supportive. B.Critical.
C.Skeptical. D.Sympathetic.
3.According to the author, what is one consequence of automation?
A.Less spending on training. B.A slowdown of globalization.
C.Social unrest and instability. D.An increase in income inequality.
4.The passage is written to .
A.argue the urgency of creating new jobs B.compare globalization with automation
C.analyze the automatability of certain jobs D.stress the importance of upskilling workers
