1 . Travel can be a lifesaver. The right vacation at the right time can give new life to your whole year, not to mention your body and mind. But in today's economy, with airlines adding new fees almost daily and ticket prices sharply on the rise, many have canceled travel as it is too expensive.     1    

Early bird gets the deal. Travel experts say that there are certain times of day when more deals are available.     2    Early morning is when the fares tend to be lowest, but it is a good idea to check every five hours to track prices as they change throughout the day. Also, it's a good idea to check again at 5 p.m. when the airlines are trying hardest to fill empty seats.

Avoid the crowds.     3    . The lowest time of the year for travel is in the Fall between Labor Day and Thanksgiving. Again, to try and fill more vacant (空着的) seats, the airlines will lower prices and offer better deals to get people to fly during this time of the year.

Right time, “wrong” place? By flying to popular destinations at unpopular times, you can secure the best prices from travel companies and airlines. Here's where flexibility in your planning can pay off. Going to the airline websites and planning your vacation around the best ticket prices offered can result in a fun, cost-effective vacation.     4    

    5     Many times the best deals on airfare can be found as part of a package rate. Most travel sites have package rates available and they are definitely worth a look. Often, the entire package (hotel, airfare, rental car) is cheaper than just the plane ticket on another site.

A．Package Deals.

B．Save Money,and Save Time.

C．Fly to popular places at unpopular times.

D．These deals are especially good on last minute package.

E．Airfares can change three times a day as airlines adjust their prices to fill up flights.

F．And maybe it can widen your horizons to a place you might never have considered.

G．However,with a few tricks,there are still many great deals to be had on air tickets.

3 . China is determined to land its astronauts on the moon and set up a scientific station there,according to a project leader.

Zhou Yanfei,deputy chief designer of China's manned space program,said on Friday that China wishes to use the manned lunar missions to carry out scientific surveys and technology demonstrations,explore ways to develop lunar resources and strengthen the nation's space capabilities.

＂A new wave of lunar explorations has been emerging in the world,with participants aiming to make sustainable missions to deepen knowledge of the moon and exploit resources there,"he said in a report delivered at the 2020 China Space Conference in Fuzhou,Fujian province."Unlike other nations,China must depend on its own science and technology to realize our goals."

The country is independently able to land its astronauts on the moon because it has the technologies,a group of well-trained,innovative professionals and high-efficiency research and management systems,Zhou said."However,our existing carrier rockets can't perform landing missions to the moon because they are not powerful enough.The Shenzhou- series manned spaceships are not suitable for lunar expeditions.We don't have a lunar landing capsule,"he said."Our ground support system was designed for operations in low-Earth orbit rather than on the lunar surface.

To solve the problem, we set out to produce a powerful launch vehicle. Zhou said researchers thought about two approaches-making a new heavy-lift rocket,or adjusting the next-generation rocket designed to carry astronauts,which is under development.Researchers prefer the latter approach because it would be easier to design and make and would become operational earlier.

The new rocket is being designed at the China Academy of Launch Vehicle Technology.Its main body will be 87 meters tall,with a diameter of 5 meters,which would make it almost twice as tall as the Long March 5,currently the biggest of China's rockets.

1. Which is NOT the goal of the manned lunar mission?

A．To explore lunar resources.

B．To perform scientific experiments.

C．To set up a scientific station.

D．To strengthen the national space power.

2. What is the main idea of paragraph 4?

A．China is not capable of pursuing the manned lunar program.

B．There are still difficulties in pursuing the manned lunar program.

C．There are a series of steps in the Manned Lunar program.

D．It is manageable to carry out the Manned Lunar program.

3. What can we infer from the passage?

A．Nations must depend on themselves to explore the moon.

B．The Long March 5 is the biggest of China's rocket.

C．The newly-designed rocket will not carry astronauts.

D．Producing a powerful launch vehicle is the most difficult part in the program.

4. What do the figures in the last paragraph imply?

A．The new rocket is big enough to perform landing missions.

B．The new rocket is being made to launch lunar spaceship.

C．China's scientific power has improved.

D．The new rocket will be put into use soon.

4 . Where in the classroom do you prefer to sit,and why? Scientists have discovered that seating preference not only shows students’ personalities,but has a great influence on their school performance.Generally speaking,students show different attitudes depending on where they sit. Based on the research, scientists have developed a funnel-like(像漏斗的) model of “learning zones(区域)” to see the relationship between seating and active learning.

In this model,the mouth of the funnel(A) is the best position for learning. Students in this front area prove to be the most active learners.They show a greater desire(渴求) for learning,which leads them to focus(集中注意力) better and take a more active part than the rest of the class.Those in the neck of the funnel(B) don’t pay the same close attention,but they ask a lot of questions,partly because of the added confidence they feel from being in a safe zone, with others around them. Less desirable is the area “outside the funnel(C,D),” which refers to the side and the back rows,where students take a less active part in classroom activities and find it hard to focus their attention, falling asleep at times.

Studies about learning zones suggest that a change in traditional seating plans can benefit students. In fact, a growing number of teachers have begun less traditional seating plans,such as “U-Type”.There are no side and back areas,so teachers can expect their students to take part in activities more actively and increase student-teacher interaction(互动).

1. According to scientists,students’ learning is greatly influenced by .

A．the number of students	B．the time of class
C．seating positions	D．the size of the classroom

2. It turns out that the students sitting in Area B .

A．sometimes fall asleep	B．feel safe and confident
C．seldom ask their teachers questions	D．try to avoid looking directly at the teacher

3. Which area is most proper for learning?

A．Area A.

B．Area B.

C．Area C.

D．Area D.

4. What does the underlined word “benefit” in the last paragraph mean?

A．Cause trouble for.	B．Take control of.
C．Give a warning to.	D．Do good to.

Once upon a time, there was an old man who couldn't read or write. When he was little, his family was so poor that he couldn't attend school. But he always dreamed of being able to read.

One day, he took his seven-year-old grandson to school.

Since he didn't have anything to do that day, he didn't leave immediately. Instead, he stood outside his grandson's classroom and looked in through the window.

The kids' teacher, who was an old man in his fifties, entered the classroom when the class began. The teacher was wearing thick glasses. He started teaching. Through watching him, the old man found something interesting, He noticed that the teacher could read nothing without putting his glasses on. As soon as he put on his glasses, he could read very well.

“How amazing! said the old man to himself.

He waited outside the classroom until the class was over and stopped the teacher.

“Excuse me, sir," said the old man to the teacher.

“Yes?” said the teacher.

“I noticed something amazing. You can't read without the glasses, right?" said the old man.

"Yes, that's true. I can read nothing without them," replied the teacher.

"But you can read once you put them on, can't you?" asked the old man.

"Yes, that's true, too," replied the teacher, wondering why the old man was asking such strange questions.

The teacher looked at the old man, who left in a hurry with a big smile on his face.

The old man, who was extremely happy, decided to go to town to find an eyeglasses store. After being unable to read so many years, he finally found an easy way to read, which cheered him up. He realized what he needed to read was just a pair of glasses.

"I can finally read,” said the old man to himself when walking to the town.

Finally, the man arrived at the town. He looked around and soon found a store with glasses in it, The man happily entered the store.

Paragraph 1:

After the old man entered the store, the store owner greeted him.

7 . Being highly successful in any field is pretty rare. It takes a combination of natural talent, luck, determination, and plenty of outside support for someone to make it big in sports, entertainment, or business. But what if competing is all that matters to you, whether you are likely to succeed or not? This was the goal of Michael Eddie the Eagle Edwards, and that he reached that goal was an amazing achievement.

Born in the U.K. in 1963, Michael was an enthusiastic downhill skier whose dream was to compete for Britain in world-class competitions. He would have liked to represent his country in the 1984 Winter Olympics, but there were a large number of downhill competitors, and Edwards didn't qualify. Seeing his chance elsewhere, he switched to ski jumping. Ski jumping didn't cost nearly as much, and there was almost no competition for a place on the Britain team.

But a number of hurdles（障碍）could have meant the end of Edwards' dream. He weighed more than most competitors, which put him at a disadvantage. He had no financial support for his training. Poor eyesight meant that he had to wear glasses under his goggles（护目镜）—not a good thing when they steamed up at high altitudes. But he couldn't let any of this discourage him. He saw himself as a true lover of the sport who simply wanted the chance to compete. Winning wasn't the point. Having the opportunity to try was all he cared about. And nothing could stop him from trying.

In the end, Edwards took 55th place in the 1987 World Championships. He then went on to the Calgary Olympics in 1988, where he finished last in both of his events. Many athletes would have been embarrassed by this result, but he is proud of his achievement to this day. His determination to fight against all the odds made him a global hero, and in 2016, the inspiring film Eddie the Eagle was made about his life.

1. What is the purpose of the first paragraph?

A．To add some background information.	B．To introduce the topic.
C．To expect an answer from readers.	D．To uncover the secret of success.

2. Why did Michael Edwards choose ski jumping?

A．There was little competition.	B．The equipment was cheaper.
C．It took less skill.	D．It was easy to win the championship.

3. After the Calgary Olympics, Edwards       .

A．switched to film making	B．was embarrassed by his results
C．felt he had reached his goal	D．was glad it was over

4. What made Michael Edwards outstanding?

A．His enthusiasm for the sport.	B．His ability to overcome physical disabilities.
C．His attitude towards the Olympics.	D．His determination to win.

10 . Tim was walking home from school one day when he noticed a boy ahead of him. He had tripped (绊倒) and dropped all of the books he was carrying along with some clothes, a baseball bat and a glove.

Tim knelt down and helped the boy pick up the things. Since they were going the same way, he offered to carry some things for the boy.
