She listened _________ to the prediction of her __________ and financial ruin, then said, “Well, if opera doesn’t __________, I’ll do something else.”
I was so proud of my __________. Truth told, I was even more proud of myself, her mid-life-career-changing mom. I was also on-my-knees __________ to my mother. Because of her example, I’d given my child the gift of __________ herself-and not in a silly usual way, like, adaptability and industry. Even at her tender age, with her frankly very privileged upbringing, she understands that circumstances can change and that __________ can, too.

School Spirit Week can be held any time throughout the year in America. It is a special time when youthful exuberance (活力) is allowed full expression.
1.There are spirit band sessions, spirit assemblies and spirit teams that have one primary goal. That goal is to promote school tradition and encourage students to recognize their school as an important part of their life.2.Some schools will use it as a kick-off for a charity (慈善) event such as collecting food for the local food bank.
A Spirit Week program can include many types of supporting activities. At most events, students like to wear identifying clothing or articles that show they are a unified group and support their school. Spirit week agendas often encourage students to wear fun and modern clothes.3.Monday might be funny hat day, followed by Tuesday's Hawaiian shirt day and Wednesday's silly T-shirt day. Thursday could be pajama day, rounded off with Friday's school colors day.4.Students decorate the walls, halls and classrooms with banners, posters and other adornments. Spirit Week posters and banners can reflect the theme of the week, the pride in the school, or show any other creative support of the school.
Parents love this special week as much as students and teachers do because parents have a great interest in the success of their children.5.
A.Spirit Weeks often have a central theme.
B.Spirit Week is about having loads of fun at school.
C.They can wear a different one for each day of the week.
D.The kids aren't the only ones dressed up for Spirit Week.
E.It makes them very happy to see the kids enthused about school activities.
F.It is also a time to recognize athletic teams competing during that season.
G.The main purpose of Spirit Week is to get the kids supportive of the school.
Teens and preteens who start the school day really early tend to weigh slightly more than those who start later. That’s the finding of a new study of nearly 30, 000 Canadians between the ages of 10 and 18. These data are the latest evidence that starting school too early can harm health.
“We know from earlier studies that when school starts too early, kids can’t get the sleep they need,” says Genevieve Gariepy. She works at Mcgill University in Montreal, Canada. Getting too little sleep can put kids at risk for a number of problems. Sleepy teens are more likely to be overweight, to have trouble concentrating and to struggle in school. They also are at higher risk of feeling depressed, using alcohol or drugs and getting in car accidents.
As an epidemiologist (流行病学家), Gariepy is interested in patterns of disease. She studies teen obesity，or extreme overweight. In this study，she wanted to know how earlier school start times might be linked to weight.
“Overweight and obesity in adolescents is a big problem in North America,” she says. The number of overweight kids has grown over the past 30 years. About one in three U. S. and Canadian teens are now overweight or obese. Kids who don’t sleep enough may be at higher risk. So Gariepy decided to find more about the impact of school start times.
Her team collected start times of 362 Canadian schools and found that among “6 to 10” graders, those who started school earlier tended to be slightly heavier for their height. Every 10-minute delay in school start time was linked, on average, to a slightly lower weight among students who were the same sex, age and height. But it’s not clear that changing school start time would help heavier kids lose weight. To know for sure, researchers would want to compare the same kids before and after changing to a later school start time.

The universe is expanding faster than it used to, meaning it’s about a billion years younger than we thought, a new study by a Nobel Prize winner says.
At issue is a number called the Hubble constant, a calculation for how fast the universe is expanding. Some scientists call it the most important number in cosmology, the study of the origin and development of the universe.
Using NASAS Hubble Space Telescope, lohns Hopkings University astronomer Adam Riess concluded in this week’s Astrophysical Journal that the figure is 9% higher than the previous calculation, which was based on studying leftovers from the Big Bang.
The trouble is， Riess and others think both calculations are correct. Confused? That’s OK, so are the experts. They find the conflict so confusing that they are talking about coming up with “new physics”, incorporating (合作) perhaps some yet-to-be-discovered particle or other cosmic (宇宙) “fudge factors” like dark energy or dark matter
“Its looking more and more like were going to need something new to explain this,” said Reiss, who won the 2011 Nobel in physics.
NASA astrophysicist John Mather, another Nobel winner, said this leaves two obvious options, “1. We’re making mistakes we can’t find yet. 2. Nature has something we can’t find yet.”
Even with the discovery, life continues on Earth the way it always has. But to astrophysicists trying to get a handle on our place in this expanding universe, this is a cosmic concern. In fact, the universe is really mystical (神秘的). Scientists have done lots of study about it but there is still much they haven’t discovered.
1.What is the finding of the new study?
A.The earth is younger than expected.
B.Many universal problems are rising.
C.The universe is growing faster than before.
D.The finding is based on past scientists’ calculations.
2.What does the underlined word “it” refer to in Paragraph 2?
A.The Hubble constant. B.The faster expanding universe.
C.The development of the universe. D.The scientific research on the universe.
3.How do the experts respond to the conflict of the finding in Paragraph 4?
A.They want to raise a new theory.
B.They want to explore dark matter.
C.They want to further calculate the finding.
D.They want to mix together both calculations.
4.What can we infer from John Mather’s words?
A.We cannot find anything useful.
B.Astronomers are making many mistakes.
C.We need to learn about the universe.
D.We cannot find something new from nature.
