【推荐1】It's been a long, wet winter. Everybody has got colds，and now we are braced for a coronavirus (冠状病毒) pandemic. Improving our immune system has never felt more important，but beyond eating more oranges and hoping for the best. what else can we do?

“When you come into contact with a virus you've never met before,” says Sheena Cruickshank, a professor of immunology at the University of Manchester, “you've got various barriers (屏障) such as skin and microbiome to try to stop it getting into your body.” If a virus breaks these defenses. it has to deal with our white blood cells，or immune cells.

However, our immune systems may have blind spots. “This might mean that our immune response doesn't recognize certain bugs (轻微传染病),” says Cruickshank, “Personally, my immune system is not necessarily very good at seeing colds.” But a healthy lifestyle will ensure your defenses are as good as they can get.

Cruickshank recommends “eating a more varied diet with lots of high-fiber foods”. Being vegetarian isn't a necessity for microbiome health, but the more plant foods you eat, the better.

To be immunologically fit, you need to be physically fit. “White blood cells can be quite inactive.” Says Prof Arne Akbar, the president of the British Society for Immunology, “Exercise activates them by increasing your blood flow，so they can do their surveillance (监督) jobs and seek and destroy in other parts of the body.” The National Health Service says adults should be physically active in some way every day, and do at least 150 minutes a week of moderate aerobic activity (hiking, gardening, cycling) or 75 minutes of vigorous activity (running, swimming fast, and aerobics class).

One of the many happy side-effects of exercise is that it reduces stress, which is next on our list of immune-improving priorities (首要事项). Stress hormones can weaken immune function, a common example of which, says Akbar, is when chickenpox (水痘) strikes twice. If you have had it, the virus never completely goes away. “During periods of stress,” he says, “it can reactivate again and we get ill”.

Exercising and eating well will have the likely knock-on effect of helping you sleep better, which is an extra benefit because a tired body is more likely to get a bug. One study last year found that lack of sleep damaged the disease-fighting ability of a type of lymphocyte called T cells, and research is showing the importance of our natural biorhythms (生物节律) overall. “Your natural biorhythms are, to some extent, controlled by sleep,” says Akbar. “If you've got a regular sleep pattern, you have natural body rhythms and everything's fine. If they go out of order, then you've got problems.”

【推荐1】According to a new study, running 50 minutes a week, at a pace between a 10- and 7.5-minute mile,helped lower the risk of death from cancer,cardiovascular disease and other causes.Working out more than that didn't mean more health benefits, say the researchers,based on a review of a number of studies.

Because running is a popular form of physical activity, study coauthor Zeljko Pedisic and his workmates chose to take a bird's eye view of what past studies of running and the risk of death had concluded. The team collected 14 papers that collectively studied over 230,000people for the effects of running on cardiovascular disease, cancer and other causes of death. Most participants(参与者) were from U.S. and European populations.

Pooling the results from these 14 studies showed that running led to lowering the risk of cancer-related death by 23%, the risk of cardiovascular-related death by 30%, and the risk of death from all other causes by 27%. Those benefits appeared even when people ran relatively slowly and for under an hour a week--less time than the World Health Organization recently.

There are some warnings to the research, though. Among other things, possibly these benefits were found because all the 14 studies of running and the cause of death only included healthy people from the get-go, the authors write. Also, only two of the papers recorded how people’s running habits changed over the years, and how often people ran was self-reported in other papers.

Though the results suggest that people might need less of a workout than the WHO might suggest, that doesn’t mean it's time to change those standards, Pedisic says. There are several other health factors that need to be examined besides the risk of death, he says, and people need other ways to get fit, too.

1. What's the new study mainly about?

A．Running as slowly as possible could keep you healthy.

B．Running led to lower risks of death than other activities.

C．Running for less than an hour a week could lower risks of death.

D．Running more than 50 minutes a week was bad for health.

2. It can be learnt from the 14 studies that__________.

A．12 of the studies self-reported how often people ran

B．most of the studies recorded people's running habits

C．only people from America and Europe were included

D．running lowered the risk of death from cancer by 30%

3. What can be inferred from the last paragraph?

A．The new study results need to be further proved

B．The WHO needs to change its standards for running.

C．People should run more than what the WHO advises.

D．Running is one of the best ways to keep fit.
