There is an English saying：“
Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their hearts, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise.
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated(忍耐) the pain for the longest time was the group which listened to a funny program.
| A．Laughter is the best medicine. |
| B．The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which diminish both stress and pain. |
| C．Although laughter helps cure the disease, doctors still can not put this theory into clinic practice. |
| D．Laughter can prolong one's life. |
| E．As a result of these discoveries, some doctors in the United States now hold laughter clinics in which they help to improve their patients' condition by encouraging them to laugh. |
| F．They have found that laughter really can improve people's health. |
| G．It increases blood pressure, the heart beating and breathing；it also works several groups of muscles in the face, the stomach and even the feet. |

【推荐1】According to a recent survey on money and relationships, 36% of people are keeping a bank account from their partner. While this financial unfaithfulness may appear as distrust in a relationship, in truth it may just be a form of financial protection.
With almost half of all marriages ending in divorce, men and women are realizing they need to be financially savvy, regardless of whether they are in a relationship.
The financial hardship on individuals after a divorce can be extremely difficult, even more so when children are involved. The lack of permanency in relationships, jobs and family life may be the cause of a growing trend to keep a secret bank account hidden from a partner, in other words, an “escape fund”.
Margaret’s story is far from unique. She is a representative of a growing number of women in long-term relationships who are becoming protective of their own earnings. Every month on pay day, she banks hundreds of dollars into a savings account she keeps from her husband. She has been doing this throughout their six-year marriage and has built a nest egg worth an incredible $100,000. Margaret says if her husband found about her secret savings he’d be hurt and would take this as a sign that she wasn’t sure of the marriage. “He’d think it was my escape fund so that financially I could afford to get out of the relationship if it went wrong. I know you should approach marriage as being forever and I hope ours is, but you can never be sure.”
Like many of her fellow secret savers, Margaret was hurt in a former relationship and has since been very guarded about her own money.
Coming clean to your partner about being a secret saver may not be all that bad. Take Colleen for example, who had been saving secretly for a few years before she confessed (坦白) to her partner. “I decided to open a savings account and start building a nest egg of my own. I wanted to prove to myself that I could put money in the bank and leave it there for a rainy day.”

【推荐2】When a scent moved gently through the air in the bedrooms of older adults for two hours every night for just six months, their memories skyrocketed. Participants in this study by UCI (University of California, Irvine) Centre reaped a226% increase in cognitive (认知的) capacity compared to the control group. The researchers say the finding transforms the long-known tie between smell and memory into an easy, non-invasive (无创的) technique for strengthening memory and potentially preventing dementia. The team’s study appears in Frontiers in Neuroscience.
The study was conducted through the UCI Center for the Neurobiology of Learning & Memory. It involved men and women aged 60 to 85 without memory disorders. They were each given a diffuser (扩散器) and seven small bottles, each containing a single and different natural oil. People in the enriched group received full-strength bottles. Control group participants were given the oils in tiny amounts. Participants put a different bottle into their diffuser each evening prior to going to bed, and it remained active for two hours as they slept.
People in the enriched group showed a 226%increase in cognitive performance compared to the control group, as measured by a word list test commonly used to evaluate memory. CT imaging revealed better integrity brain pathway. The pathway affects decision-making ability and usually becomes less powerful with age. Participants also reported sleeping more soundly.
Scientists have long known that the loss of olfactory capacity, or ability to smell, can predict development of nearly 70 different kinds of diseases including Alzheimer’s and other dementias. Evidence emerges about a link between smell loss due to COVID and later cognitive decrease. Researchers have previously found that exposing people with moderate dementia to up to 40 different scents twice a day over a period of time boosted their memories and language skills, alleviated depression and improved their olfactory capacities. Later, the UCI team decided to try making this technique easier for older adults.

| A．To report a study on scent exposure boosting memory. |
| B．To show a method to predict development of diseases. |
| C．To reveal the relationship between smell and memory. |
| D．To draw public attention to memory loss in older adults. |

【推荐3】Cell phones：Is there a cancer link?
Could your cell phone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and Wi-Fi could be responsible for a range of illnesses, from rashes to brain tumors.
Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there’s a greater than 95 percent chance that power lines can cause childhood leukemia (白血病). Also there’s a greater than 90 percent chance that cell phones can cause brain tumors. “It’s apparent now that there’s a real risk, ”said Carpenter.
But others believe these concerns are not justified. Dr Martha Linet, head of radiation epidemiology (流行病学) at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I don’t support warning labels for cell phones, ”said Linet. “We don’t have the evidence that there’s much danger.”
Studies so far suggest a weak connection between EMFs (电磁场) and illness—so weak that it might not exist at all. A multinational investigation of cell phones and brain cancer, in 13 countries outside the US, has been underway for several years. It’s funded in part by the European Union, in part by a cell phone industry group. The final report should come out later this year, but data so far don’t suggest a strong link between cell phone use and cancer risk.
1. From the passage we can learn that some people are worried because________.| A．they have evidence that the use of cell phones can lead to cancer |
| B．they feel surprised and alarmed about cell phone use |
| C．some experts have given a warning |
| D．cell phones are responsible for brain tumors |
| A．the worrying is unnecessary |
| B．cancer—warning labels should be on cell phones |
| C．there is a link between cell phones and cancer |
| D．cell phones have nothing to do with cancer |
| A．Optimistic. | B．Objective. |
| C．Opposite. | D．Casual. |
| A．explained | B．confirmed （证实、确认） |
| C．classified | D．restricted （限制） |
