My husband and I had been married nearly twenty-two years when I acquired Stevens-Johnson syndrome, a disorder where my immune（免疫的）system responded to a virus by producing painful blisters. Although my long-term evaluation was good, I, who had been so fiercely independent, rapidly became absolutely helpless.

My husband, Scott, stepped up to the plate, taking care of kids and cooking dinners. He also became my personal caretaker, applying the medicine to all of my blisters because my hands couldn't do the job. Needless to say, I had negative emotions, bouncing from embarrassment to shame caused by total reliance on someone other than myself.

I recovered from my illness, but I couldn't seem to recover from the thought that I loved my husband less than he loved me. This seeming distinction in our love continued to annoy me for the year following my illness.

Then recently Scott and I went on a long bike ride. He's an experienced cyclist; I'm quite the green hand. At one point with a strong headwind and sharp pain building in my tired legs, I really thought I couldn't go any further. Seeing me struggle, Scott pulled in front of me and yelled over his shoulder, “Stay close behind me.” As I followed his steps, I discovered that my legs quit burning and I was able to catch my breath. My husband was pulling me along-again.

     I pray my husband will always be strong and healthy. But if he should ever become the struggling one, whether on a bike ride or with an illness, I trust Ill be ready to call out to him, Stay close behind me--my turn to pull you along.

    A woman was sitting by herself in a movie theatre. The movie she was about to see was a musical version (版本)of a very successful book that had sold a million copies that year.

    As the woman was waiting for the movie to begin, she noticed that the theatre was very crowded but the two seats next to her were empty.

    Suddenly a large man carrying a big fur coat walked down the aisle (走廊) and sat down, placing the fur coat on the seat next to her.

    When the lights went out, the fur coat began to move, and the woman realized it was not a coat but a large furry dog. He was sitting up in the seat, watching the movie screen with great interest. As soon as the movie started, the dog began to nod his head and beat his paws（爪） in perfect time to the music.

    When the movie was over, the woman turned to the man and said, "Excuse me, sir, but I've never seen such a well-behaved dog in a movie theatre before. Does he go to the movies often?"

    "Oh, yes," replied the man.

    "And he seemed to enjoy everything so much," she said, "It was just amazing!"

    "As a matter of fact, it surprised me, too," said the man. "He hated the book!"

    If you live in a big city, there are many thing to drive you crazy on your daily route, and it's not just overcrowded subway trains.

    Vicky Zhao is a mainlander working in Hong Kong. For her, one thing she can't put up with is people standing on the wrong side of the escalator(自动扶梯) in subway stations. "Escalators help us move faster and save time. It isn't a place to rest," the 24-year-old says. "I often see tourists block the way with their suitcases or chatting on the escalators during rush hours. It annoys me to no end."

    Admitting she is not the patient type, Zhao says things are much better in Hong Kong than in cities on the mainland where "stand right, walk left" signs are often ignored.

    The logic behind the "stand right, walk left" escalator etiquette(礼仪) seems obvious. Even though you may want to catch your breath while you're transported up or down, you should still consider others and leave enough space for people in a hurry, so that they can run and catch the train.

    Many cities' escalators, including London's and Beijing's, use the "stand right, walk left" system to speed up the flow of people. (Australia is an exception and you should stand on the left side instead.) But some cities discourage people from moving on escalators out of safety reasons. In Hong Kong's subway stations there are regular announcements asking people to "stand still" on escalators. Even so, most people in this fast-paced city observe the "stand right, walk left" etiquette.

    But the people who stand on escalators defend themselves by telling the walkers not to be so impatient. The BBC quotes one stander as saying: "If the person is in such a rush, why not just take the stairs? Even when the escalator is packed and there's nowhere to move, I see these same people complaining about not being able to pass."

    Whatever the escalator etiquette is in the place you live or visit, do what most people are doing and always be mindful of others: leave enough space between each other, don't stay at the end of the escalator, and if someone is blocking your way, a simple "excuse me" is enough.

    A Chinese scientist's attempt to produce the world's first gene-edited babies who are immune to HIV has caused floods concern.

    In an online video posted on Monday, He Jiankui, a biological researcher, announced that a pair of twin baby girls, Lulu and Nana, was born healthy a few weeks ago with genetic editing technology that can prevent them from being infected with HIV.

    He, who was believed to be in Hong Kong on Monday to attend the Second International Summit on Human Genome Editing, could not be reached for comment. But his announcement sparked a heated argument concarning medical ethics（伦理）and effectiveness.

    The Shenzhen Health and Family Planning Commission said on Monday evening that it had not received any ethical assessment application for the study, which is required as a prior condition for such experiments.

    More than 120 scholars from universities and institutes with high status from China and abroad,such as Tsinghua University and the Massachusetts Institute of Technology (MIT),strongly condemned the research in a signed statement, saying the “research” lacks effective ethics inspection, and it amounts to human experimentation,which is “crazy”.

    In the statement, published on Sina Weibo, the scientists said any attempt to make changes to human embryos with genetic editing and give birth to such babies involves high risk as an inevitable part, due to inaccuracies in existing genetic editing technologies.

    “Scientists all over the world dare not make such attempts due to the huge risks and more importantly, ethics. The government must make quick legal moves to strictly supervise（监督）such research. The Pandora's Box has been opened, and we may still have a chance of closing it before it is too late,”the statement said.

    Tsui Lap-chee, president of the Academy of Sciences of Hong Kong, said a lot of issues may occur in gene editing. If one gene is edited, it will affect others that interact with it. And the whole genome, a collection of genes, may also be affected.

    A young woman carrying a three-year-old child got on a bus. The conductor hurried to give her a warm welcome and then kindly asked the other passengers to make more room for the woman and her kid. On seeing this, people were surprised and began to talk." You know this conductor used to be very rude. Now suddenly he has changed his bad behavior, "said a middle-aged man.

    "Yes, he should be praised and we must write a letter to the company," said a second passenger." That's right," another lady said, "I wish a newspaper reporter were here so that more people could learn from this conductor."

    Just then a gentleman who looked like a teacher turned to the conductor and said, "Excuse me, but can I know your name, please? Your excellent service must be praised…"

    Before he could open his mouth, the three-year-old kid sitting on the young woman's lap interrupted, "I know his name; I call him Dad."

    It was only a dollar. Belscher noticed it on the floor as he sat at the back of his English class. When the school day ended, Belscher wandered back to the classroom. The old bill was still there. He could easily have pocketed it without thinking twice. Instead, he picked it up and brought it to his English teacher, Mattison.

    "It wasn't my money," Belscher says. Mattison was a little surprised he'd turned the dollar in, knowing a lot of people would have just kept it. She suggested that Belscher tape(贴) it to the whiteboard at the front of the classroom, where she always puts lost things.

    Rose, another student, was in English class after break when he spotted the dollar on the whiteboard. After class, he asked Mattison why it was there. She was still waiting for the original owner to claim it, so she replied, "I don't know." Rose took the tape from Mattison's desk and taped a second dollar to the board.

    That got it rolling. The sight of the two dollar bills, side by side, started something in Mattison's students. They started asking about the purpose of the money, to which Mattison always gave the same answer: She didn't know. At that point, it was true.

    More students, curious, taped up single dollar bills. Mattison started to leave the tape on the tray of the whiteboard. The effort snowballed. Even with no clear purpose, many students wanted to be part of whatever this was. The amount continued to grow over several weeks, until it reached $175.76.

    That left Mattison to make the best decision. She kept thinking about her brother-in-law, Jack Hains. Eight years earlier, Jack had died of amyotrophic lateral sclerosis (ALS), a rare and devastating neurological disease(神经疾病).

    Mattison explained to her classes that Jack had raised money every spring for the ALS Therapy Development Institute, established to seek a cure for the disease. She asked the teens whether they minded if she donated the dollars in their names in honor of Jack.

    Their answer was to tape enough money to the whiteboard over the next few days to push the amount to $321.06. Mattison, choking back tears as she recalls the moment, says she carefully picked the cash off the board and made the donation just before the beginning of May, which is National ALS Awareness Month. That was Saturday. By Monday afternoon, eight more dollars had been taped to the board.
