【题目】 Mercury(水星) is the closest planet to the sun. It is a planet slightly larger than the Earth’s moon. It is covered in craters. Some craters have ice in them, even though the planet is hot. Sunlight never touches some parts because of the planet’s special position. Without air, there are great temperature differences between the coldest and hottest parts. Mercury days are so long that there are big differences between temperatures on the daylight side and the night side.

Mercury was created billions of years ago, when big rocks ran into each other. After these accidents, the planet was frequently visited by meteorites (流星) for several hundred million years. There were also many volcanic eruptions. As the planet cooled, the thin, rocky outside shell reduced in diameter(直径) by about 3 kilometers.

The Caloris Basin is one of the largest craters on Mercury. This big crater is 1, 300 kilometers wide and was formed when a large rock, about 100 kilometers across, knocked into the surface. Beethoven, another large crater, is 643 kilometers across.

The cliffs on Mercury are up to 2 kilometers high and hundreds of kilometers long. The cliffs were formed when the thin surface fell apart, as volcanic activity slowed down and Mercury became cooler.

One Mercury day lasts about 59 Earth days. Mercury takes about 88 Earth days to have a complete year, instead of the 365 days that we have on the Earth. Mercury speeds around the sun so that there are three Mercury days every two Mercury years! Mercury has a strange relationship with the Earth. Every 117 days, when Mercury is closest to the Earth, it always has the same side facing us.

Mariner 10 is the only spacecraft to visit Mercury. It made three visits to Mercury in, the 1970s, taking photos of many cliffs and craters. Although the first three visits answered many questions, they have raised others.

1What is the surface of Mercury like?

A.It’s generally flat.B.It’s hot everywhere.

C.It’s bright everywhere.D.It’s cold in some parts.

2Why did Mercury’s diameter get smaller?

A.A drop in temperature changed its size.

B.A great many meteorites ran into it.

C.It got out of shape as time passed.

D.Lots of surface rocks fell off.

3What do we know about Mercury?

A.One Mercury day lasts about 88 Earth days.

B.It turns around the sun faster than the Earth.

C.Six Mercury days are two Mercury years.

D.It has more cliffs than large craters.

4What happened after Mariner 10’s three visits to Mercury?

A.Another spacecraft visited Mercury.

B.New cliffs and craters were formed.

C.New signs of volcanic activity appeared.

D.Lots of new puzzles needed to be solved.

【题目】 In some US states, gym class is changing. Many schools are focusing on getting students ready for life after high school. They are looking for ways to leave even the least athletic kids with the will and skills to keep moving. For gym teachers, that means less focus on who is best at a sport. It means less rope climbing and dodgeball(躲避球).1

A New Model

In one New York school district, there is no “gym” class. 2They include dance, self- defense and rock climbing. They include mountain biking, in-line skating, and boating.

“We want our kids…, to be active for life,” said Ron Whitcomb. He manages the physical education, or PE, program for the Victor, New York, school district.

A US law passed in 2015 increased the importance of health and fitness in education. It also gave more funding(资金) to PE programs.

Whitcomb’s program started before that law passed. 3Connecticut, Vermont and Michigan are all planning to improve PE’s place in their schools.

Outside the Gym

Tracy Krause teaches PE in Washington State. For a few years, she has taken students fly-fishing and rock climbing. 4It combines PE, English, and science into one program. “We want kids to leave with a plan for the future,” Krause said. “I think the same needs to be true about their health.”

Lifelong Skills

In Washington, D. C, all second-graders learn to ride bikes. Fourth- and seventh-graders learn parkour(跑酷). Parkour teaches students to jump, climb and roll in the fastest way they can. Sixth- graders learn how to read a compass. High schoolers swim. 5

Teachers hope to keep students liking, not hating, PE. That means finding sports or activities they enjoy.

A.They are also cutting back on team sports.

B.It means more bike riding and outdoor hikes.

C.Other schools are now following his program.

D.Instead there is a list of different fitness classes.

E.The school district’s goal is to teach lifelong skills.

F.She is part of her school’s “Outdoor Academy” program.

G.Kids who are not as athletic sometimes hate playing team sports.

【题目】阅读下面材料,在空白处填入适当的内容(1个单词)或括号内单词的正确形式。

The fire at Notre-Dame Cathedral de Paris has raised questions about the condition of thousands of other cathedrals and historic 1 (structure) across Europe. It also raises questions about whether European government are doing enough 2 (keep) up and care for such buildings.

Tibor Navracsics, the European Union’s top cultural official, told The Associated Press that “we are so used to our outstanding cultural heritage in Europe that we tend to forget that it 3 (need) constant care and attention.” Some people say the fire was a wake-up call, not just for Europe,4 for the whole world.

Large fires have long robbed humanity 5 knowledge, art and treasures. In 2015, the German engineering company Siemens 6 (find) that Scotland had about ten damaging fires a year, while England lost at least a dozen listed buildings a year. In Germany, seventy historic buildings have been 7 (heavy) damaged since 2000.

Experts say that 8 is needed is continuous attention and maintenance. Some say world-famous monuments like Notre-Dame are the 9 (drive) force behind tourism and should get more respect. Sneska Quaedvlieg-Mihailovic, who heads the heritage group Europa Nostra, noted the 10 (important) of such respect. “Cultural heritage is a gold mine. You cannot exploit it and then just leave the mine and go to another one.” She said.

【题目】 A few years ago, a doctor gave a wrong prescription to a 9-year-old boy because he had accidentally clicked the next medicine listed in the drop-down menu. Unfortunately, the boy died.

Dr. Gidi Stein heard the story and felt forced to do something. “It was like killing someone with a spelling error. He just clicked on the wrong button,” Stein said. “One would have thought there’d be some kind of spell-checker to prevent these terrible things from happening. But apparently this is not the case.”

Several things were immediately obvious to the 54-year-old Stein, who had previously studied computer science. “If you look at this problem from a bird’s eye view, there were so many places down the line where this decision could have been stopped — from the physician to the pharmacy (药房) even to the mother. All of them had all the relevant information to have a judgment call that this was just the wrong drug for the wrong patient.” For Stein, it represented a systemic failure.

Stein compared this with credit cards. “If you use your credit card in the daily routine over time, a pattern of how we use our cards comes out: the grocery store, the gas station in our local town. If your credit card would appear tomorrow in Zimbabwe, it would be unusual. The credit card company would call you and say, ‘Hey, was that you?’”

But nothing like that existed in the field of prescription drugs. So Stein set up a company called MedAware. He came up with a machine learning outlier detection (异常检测值) system. In other words, he trained the computers to realize if a doctor accidentally prescribed the wrong medicine.

The system is already used in hospitals and doctor’s offices. To date, MedAware has used their technology to help nearly six million patients in the United States and Israel.

1What led to the boy’s death?

A.The doctor’s carelessness.B.The drawback of the computer.

C.The doctor’s poor medical skill.D.The incomplete health care system.

2What does Stein feel about this medical accident?

A.Angry.B.Frightened.

C.Embarrassed.D.Regretful.

3What can MedAware’s technology do?

A.Help doctor choose right medicine.B.Reminds patients to take medicine.

C.Introduce new drugs to doctors.D.Check the prescription.

4Where is this text most likely from?

A.A diary.B.A guidebook.

C.A magazine.D.A science fiction.

【题目】Make Your Fitness Resolution Stick
