Unhappy people glue（使粘牢） themselves to the television 30 percent more than happy people.

The finding, announced on Thursday, 1 from a survey of nearly 30,000 American adults conducted between 1975 and 2006 as part of the General Social Survey.

2 happy people reported watching an 3 of 19 hours of television per week, unhappy people reported 25 hours a week. The results held even after 4 into account education, income, age and marital status.

In addition, happy individuals were more socially 5 , attended more religious services, voted more and 6 a newspaper more often than their less-chipper（没有精神的） counterparts.

The researchers are not sure, though, whether unhappiness 7 more television-watching or more viewing leads to unhappiness.

In fact, people say they like watching television: Past research has shown that when people watch television they 8 it. In these studies, participants reported that on a 9 from 0 (dislike) to 10 (greatly enjoy), TV-watching was nearly an 8.

But perhaps the high from watching television doesn't 10 .

"These conflicting data 11 that TV may provide viewers with short-run 12 , but at the expense of long-term malaise(精神欠爽)," said researcher John Robinson, a sociologist at the University of Maryland, College Park.

In this case, even the happiest campers could turn into Debbie-downers if they continue to 13 at the TV. The researchers suggest that over time, television-viewing 14 push out other activities that do have more lasting 15 . Exercise and sex come to mind, as do parties and other forms of socialization known to have psychological benefits.

Or, maybe television is simply a refuge(慰藉物) for people who are already 16 .

"TV is not judgmental 17 difficult, so people with 18 social skills or resources for other activities can engage in it," Robinson and UM colleague Steven Martin write in the December issue of the journal Social Indicators Research.

They add, " 19 , chronic unhappiness can be socially and personally debilitating（使人衰弱的） and can interfere with work and most social and personal activities, but even the unhappiest people can click a remote and be passively 20 by a TV."

The researchers say follow-up studies are needed to tease out the relationship between television and happiness.

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

Two brightly colored butterflies have just flown by. They seems to be exactly alike, but actually one is a little larger than the other. The smaller one has a wingspread of less than three inches and also a black line on its back wings.

At first sight, it is hard to tell them apart. Would you guess from this that they are different-sized butterflies of the same species? If you said yes to either question, you would be wrong, for these look-alikes belong to quite different families.

The larger insect is the monarch butterfly (黑脉金斑蝶). As a baby insect, the monarch feeds on milkweed, which seems to give the monarch a disagreeable taste and smell. Birds that eat butterflies soon recognize the monarch and quickly learn to leave it alone.

Birds would find this insect tasty, but because it looks like the monarch, birds keep away from it. The viceroy’s similarity to the monarch gives it some protection from its enemies and helps it survive.

There are other pairs of look-alike butterflies, bees and moths. In each case, one either has a disagreeable taste or smell, or can give a painful sting (叮咬). The larger is called the model. （词数206）

A. The smaller insect is the viceroy (副王峡蝶), which feeds on the leaves of trees.

B. The larger insect has a wingspread (翼长) of up to four inches.

C. The bright coloring of the monarch acts as a warning sign to its enemy.

D. Birds protect their babies from eating such dangerous enemies.

E. The insect that imitates this model for protection is called the mimic（保护色）.

F. Or that they are different species of butterflies but close relatives belonging to the same family?

G. Do you like this kind of special species?

My father was in the navy, which meant that my mother was married to both my father and the sea. As was often the , we had to pack our belongings into boxes and those we had grown to love. We would arrive at our new home and find ourselves once again standing at the pier (码头) good-bye to my father as his ship pulled him away from us. My mother would turn my brother and me around before the ship was out of , wipe our tears, and take us back home to start the process of in the new environment again.

Throughout the years of changing , schools and friends, there remained one constant in my childhood — my mother. For both my and me, she was the cook, maid and teacher. She played these roles while some type of part-time job. Leaving a career is just one of the sacrifices which my mother made for my family as we moved around the world with our father every three years or so. she had to deal with only a small budget, my mother, , managed to make each house the very home that is safe and .

This probably sounds like a depressing way to live, with two small children: “single”

parenthood, short-term friendships, and the inability to her career or establish a home. But it was not for my mother. She turned this into adventure for us all! Each relocation (变换位置) was a chance to another part of the world. My mother greeted each new culture, climate and neighborhood. Each new house was a to rearrange furniture, make curtains and pictures. Every part-time job was an opportunity to learn something new and work with interesting people.

No matter how difficult the life was, she was always having a attitude. She always had strength in the face of struggle and change. My mother was so all those years during my childhood — she was my island in a sea of change. She is my hero.

We all know that DNA has the ability to identify individuals, but because it is inherited, there are also regions of the DNA strand which can relate an individual to his or her family(immediate and extended);tribal group and even an entire population. Molecular Genealogy(宗谱学)can use this unique identification provided by the genetic markers to link people together into family trees。Pedigrees（家谱）based on such genetic markers can mean a breakthrough for family trees where information is incomplete or missing due to adoption，illegitimacy（违法）or lack of record. There are many communities and populations which have lost precious records due to tragic events such as the fire in the Irish courts during Civil war in 1921 or American slaves for whom many records were never kept in the first place.

The main objective of the Molecular Genealogy Research Group is to build a database containing over 100,000 DNA samples from individuals all over the world. These individuals will have provided a pedigree chart of at least four generations and a small blood sample. Once the database has enough samples to represent the world genetic make-up, it will eventually help in solving many issues，regarding genealogies that could not be done by relying only on traditional written records. Theoretically, any individual will someday be able to trace his or her family origins through this database.

In the meantime, as the database is being created, molecular genealogy can already

Verify（鉴定）possible or suspected relationships between individuals。“For example，if two men sharing the same last name believe that they are related，but no written record proves this relationship，we can verify this possibility by collecting a sample of DNA from both and looking for common markers（in these case we can look primarily at the Y chromosome（染色体），”explain Ugo A. Perego, a member of the BYU Molecular Genealogy research team.

1) The possible research of family trees is based on the fact that _____________.

A) genetics has achieved a breakthrough

B) genetic information contained in DNA can be revealed now

C) each individual carries a unique record of who he is and how he or related to others

D) we can use DNA to prove how distant an individual is to a family, a group or a population

2) If two men suspected for some reason they have a common ancestor,__________.

A) we can decide according to their family tree

B) we can find the truth from their genetic markers

C) we can compare the differences in their Y chromosome

D) we can look for written records to prove their relationship

3) Which of the following CAN NOT be inferred from the passage?

A) we are a walking, living, breathing record of our ancestors

B) Many American slaves did not know who their ancestors were

C) An adopted child generally lacks enough information to prove his identify

D) Molecular genealogy can be used to prove a relationship between individual

These cases show that many complaints do not go ________ by the managers of the store, mainly because not all customers report them.
