For as long as we've known about it, humans have searched for a cure for cancer. Across the world, countless amounts of time and money have been spend on researching a way to stop the terrible disease.

    But now, it seems like the answer could have been inside our own bodies the whole time.

    Recently, the Food and Drug Administration (FDA) in the US, a government agency that's responsible for healthcare, approved a new form of gene therapy that could mean the end of a certain type of cancer.

    The therapy allows scientists to 'train” the immune cells of sick patients to fight leukemia – a blood cancer that mostly affects young people.

    The exciting new treatment works by removing healthy immune cells from the patient, known as T-cells, which are then altered to be able to “hunt down” cancer cells.

    The cells are then put back into the patient, before they begin to get rid of the patient's leukemia over time, similar to how the body fights off other illnesses.

    'this is truly an exciting new day for cancer patients,” Louis J. DeGennaro, president of the Leukemia and Lymphoma Society, said in a news release. Up until now, a drawn-out （持续很久时间的）and painful bone marrow transplant was the only option for many leukemia patients.

    In this procedure, healthy blood cells are taken from a donor and placed into the sick patient, who also has to go through chemotherapy to allow their body to adjust to the new cells.

    But with a recovery rate of around 83 percent–according to a news release published by the FDA–it's hoped that the days of painful trips to the hospital, or even death, are over for leukemia sufferers.

    “We're entering a new frontier in medical innovation with the ability to reprogram a patient's own cells to attack a deadly cancer,” FDA commissioner Scott Gottlieb said in the release.

    “New technologies such as gene and cell therapies hold the potential to transform medicine and... our ability to treat and even cure many intractable（难治的） illnesses.”

    {#blank#}1{#/blank#}You probably think you will never be a top student. This is not necessarily so, however. Anyone can become a better student if he or she wants to. Here's how:

    Plan your time carefully. When planning your work, you should make a list of things that you have to do. After making this list, you should make a schedule of your time. First your time for eating, sleeping, dressing, etc. Then decide a good, regular time for studying. {#blank#}2{#/blank#}A weekly schedule may not solve all your problems, but it will force you realize what is happening to your time.

    Find a good place to study. Look around the house for a good study area. Keep this space, which may be a desk or simply a corner of your room, free of everything but study materials. No games, radios, or television. When you sit down to study, concentrate on the subject.

    Make good use of your time in class.  {#blank#}3{#/blank#}Listening carefully in class means less work later. Taking notes will help you remember what the teacher says.

    Study regularly. When you get home from school, go over your notes, review the important points that your teacher is going to discuss the next day, read that material.  {#blank#}4{#/blank#} If you do these things regularly, the material will become more meaningful, and you'll remember it longer.

    Develop a good attitude towards tests. The purpose of a test is to show what you have learned about a subject. They help you remember your new knowledge. The world won't end if you don't pass a test, so don't be over worried.

    It is easier to float in the ocean than it is to float in a swimming pool. Do you know why?

    Ocean water is full of salt— and salt water can hold up more weight than fresh water. See for yourself!

    You Will Need:

    3 cups of warm water

    Measuring cup (量杯)

    Wide-mouthed jar

    Salt

    Spoon

    Raw (生的)potato

    You Will Do:

    ⒈Pour 1.5 cups of warm water into the jar.

    ⒉Add 1/3 cup of salt.

    ⒊Stir(搅拌) until the salt is completely dissolved.

    ⒋Add another 1.5 cups of water. Pour it slowly over the back of the spoon into the jar so that the two liquids will not mix together.

    ⒌Gently place the potato into the jar. Do not drop it.

    What Will Happen:

    The potato will sink— but only halfway!

    Why?

    Salt water is heavier than fresh water, so it will stay on the bottom. The fresh water will remain on top.

    The potato is heavier than the fresh water, but it is lighter than the salt water. That is why the potato will sink halfway down.

    Humor plays an important role in relationships. In new relationships, humor can be an effective tool not just for attracting the other person but also for overcoming any awkwardness or embarrassment. {#blank#}1{#/blank#}

    Sharing the pleasure of humor creates a sense of connection between two people. When you laugh with one another, you create a positive tie between you. This tie acts as a strong buffer(缓冲) against stress, disagreements, disappointments, and bad patches in a relationship. And laughter really is infectious. {#blank#}2{#/blank#}But don't worry if you're not naturally a lighthearted, humorous person—you can learn to access your playful side and develop your sense of fun.

    Like any tool, humor can be used in negative as well as positive ways. Humor can only help you overcome relationship problems when both partners can understand the joke. {#blank#}3{#/blank#} If your partner or friend isn't likely to appreciate the joke, don't say or do it. Humor in relationships should be equally fun and enjoyable for both people.

    Don't use humor to cover up other emotions. {#blank#}4{#/blank#}That's when it is used as a cover for avoiding, rather than coping with, painful emotions. You can be funny about the truth, but covering up the truth isn't funny. When you use humor and playfulness as a cover for other emotions, you create confusion and mistrust in your relationships.

    {#blank#}5{#/blank#}The important thing is to find enjoyable activities that help you embrace your playful nature with other people. As humor and play become an inseparable part of your life, you'll begin to find daily opportunities for using your new-found skills to help build and maintain your relationships.

A. Humor can help you and your loved one.

B. There are times when humor is not healthy.

C. It's important to be sensitive to the other person.

D. It's never too late to develop your humorous side.

E. The more you joke, play, and laugh—the easier it becomes.

F. Just hearing someone laugh can make you smile and join in on the fun.

G. In longer-term relationships, humor can keep things exciting and fresh.
