Planet Hunter
When Geoff Marcy was 14, his parents bought him a telescope. Every night, he would go onto the roof outside his window to see the wonders of the sky.
“What excited me most was whether there were planets（行星）in other solar（太陽的）systems where life might exist, ”he says. “I decided to try to find planets orbiting（沿…軌道運行）other stars like our Sun.”
And he did. “My fellow researcher, Paul Butler, and I found our first planet in 1995, ”Dr. Marcy says. “We worked for ten years without finding anything! But we stuck with it, and our patience paid off. ”
Since then, the two scientists have discovered 65 of the more than 100 planets found orbiting other stars. Dr. Marcy and Dr. Butler also spotted the first “family”of three planets. In June 2002 they announced another discovery: a Jupiter-like（像木星一樣的）planet orbiting star 55 Cancri.
At first, the two researchers found only planets that orbit close to stars. Recently, the scientists found planets farther out. The planet orbiting 55 Cancri is a major breakthrough: it is the first sighting of a large gas planet about the same distance from the star as Jupiter is from the Sun.
Why is this important? Scientists think that life on Earth may exist because of two special features（特徵）in our solar system. The first is Jupiter.
“Because it’s so big, Jupiter pulls comets and asteroids（小行星）, or they all come and hit the Earth. ”Dr. Marcy explains. “Without Jupiter, life on Earth would likely have been destroyed. ”
A second feature is that Earth is a rocky planet where liquid water, which is necessary for life, can exist. Unlike gas planets, rocky planets like Earth have surfaces where water can gather in pools and seas, which may support life. A huge space exists between the Jupiter-like planet and two other planets that lie close to 55 Cancri. Is there an Earth-like planet in the space, too small for us to notice? If so, says Dr. Marcy, “We would have two striking similarities to our solar system: a Jupiter-like planet and an Earth-like planet. And there may be life! ”

Everyone has many different relationships. Some relationships are with family members, some are with friends and some are love relationships. Each relationship is different, and all relationships change over time as the people within them grow and develop. Most relationships contain a combination of healthy and unhealthy characteristics.
Healthy relationships have certain characteristics. Each partner feels whole without the other even though the two people enjoy being together. They communicate effectively and honestly. In a healthy relationship, both partners accept the other as he or she is. There are no unrealistic expectations or attempts to control the other person. In healthy relationships, changes on both sides are recognized and appreciated. Both partners have established healthy, comfortable limits based on their own standards. There is a balance between togetherness and separate lives of each partner.
Some relationships may contain unhealthy characteristics. One person may expect his or her partner to fulfill all their needs. One or both partners may be jealous and demand complete devotion. The desire to control others is another unhealthy characteristic. There may be a tendency to dominate the other person and the relationship. Selfishness may be a part of an unhealthy relationship. Those who are selfish only take care of their own comfort, pleasure and interest excessively but without regard for others. The last characteristic that may exist in unhealthy relationships is abuse, which involves emotional and physical mistreatment.
When unhealthy characteristics exist within a relationship, partners may choose to work toward making the relationship healthier. However, both partners must be willing to make efforts to overcome the negative characteristics of the relationship. Counseling services within schools and communities help families and couples strengthen their relationships. When problems within a relationship are not surmounted, one or both partners may decide to end the relationship.

Most of the cow won’t even be used 3.meat people eat. By the time a hamburger finally lands onto a dinner plate, It has made bad effect 4.the environment.
We can reduce the production of global warming gases by eating less beef. Other kinds of meat like pork and chicken do 5.harm to the environment ---at least in terms of the amount of greenhouse gases released(釋放).However, all kinds of meat are harder on the planet 6.vegetables. 7.we’d change our diet to less meat and more vegetables, in fact it’s an environmentally friendly lifestyle and it’s beneficial 8.the environment.
I tried to grow a gardenia （梔子花）．I had tried everything my mother taught me about caring for houseplants—more light, less water, spraying, even replanting, but _1_ seemed to work．
I _2_ Mom were here now．Mother’s Day was coming up, the second one since her death, and the pain of losing her was still so fresh．There is a Mother’s Day _3_ I follow．One wears a red flower if one’s mother is _4_ and a white one if she is not．I had hoped that planting a white gardenia, Mom’s favorite flower, would help me through the sorrow of her _5．
Mom had a way with all things _6_．My sister and I always joked, “Mom could _7_ a telephone pole grow leaves and bear fruit．”
Why can’t I? I thought．Still, I couldn’t stand throwing the dead plant away．Instead, I placed it into a dark corner of our bathroom．I didn’t even water it．I just left it there _8_ I could deal with it．
My husband asked me if I was going to wear a white flower to church that Mother’s Day．“Yes,” I told him, “but I need a _9_ gardenia．” I added silently．
Sunday morning I woke up early to get dressed and made for the _10_．Still _11_, I walked to the bathroom．Suddenly I was woken up by a pleasant scent （香味）．I pushed the door open and stepped into the bathroom．That morning I knew I would be ready to wear a small white flower for Mom．In that dark corner, _12_ as if it had a light of its own, bloomed a perfect white gardenia!
