Here comes the good news for students who have too much work to do after school. On March 5, Premier Li Keqiang gave th e speech in this year’s Government Work Report. Education is one of the highlights.
“We will give attention to the problem of heavy extracurricular burdens (课业负担)on primary and secondary school students, ” Li said during his speech.
Chinese parents often spare no effort or money to further their children’s education. Many send their children to after-school classes. In 2016, China had about 180 million school-aged students, according to a reporter by the Chinese Society of Education. More than 137 million of them took part in extracurricular classes or off-camps training.
To deal with this problem, the Ministry of Education ( MOE )(教育部), drew up guidelines on Feb 26 that call for actions to be taken. Their targets are private training schools that create additional workloads and pressure for students.
The actions will be aimed at training schools which have no professional qualifications or cause safety risks, said Lu Yugang, an official from the MOE. He also said reducing the workloads for students should be a priority. It is a must do, for children to study happily and grow in a health manner. . . and sleep an additional half-hour or an hour.

C
Since I was a boy, I have always looked down open manholes with curiosity, so I welcomed the opportunity to explore and write about the world beneath New York City. With a group of 11 “sandhogs” —the nickname (别名)for the workers who build New York’s underground —I boarded a slow, shaky elevator (升降机)lit by a single light. Slowly we went down deeper through 200 meters of rock. The sandhogs were building a new tunnel(隧道) to bring water into the city. The present tunnel system carries more than 5. 6 billion liters of water every day. That’s enough water to fill more than 2, 200 Olympic-sized swimming pools.
As we got down, it got dark and the air got cool. I looked up into darkness and down into deeper blackness, then the elevator stopped, and everyone got out. Then came the hard part, climbing another 10 meters down a long, slippery metal ladder. At the bottom was a dark tunnel filled with dust and smoke. Sandhogs were using a special machine to cut through the hard rock. The tunnel goes forwards slowly — only four meters a day — and with each day come new dangers. Sandhogs live in great fear of being hurt by sharp pieces of explored (爆炸)rock. Their bodies are covered in such scars.
“Why do this work?” I asked Brian Gallagher, a sandhog for 16 years. Brian’s father was a sandhog, too, but it is not tradition that brought him here. “It's the money, ” he said. An experienced
sandhog earns over $ 100, 000 a year. The rewards are well deserved (奖金丰厚). A sandhog‘s chances of dying on the job are far greater than those of an above -ground construction worker, or even a New York City police officer. “Everything down here can kill you, ” one sandhog said. They know many more workers will die before the tunnel is completed.
66. The passage is mainly about ____ .
A. a tunnel system
B. making tunnels
C. a high pay
D. a dangerous job
67. Brain Gallagher works as a sandhog because ____ .
A. it is his family tradition
B. it pays well
C. very few people do it
D. he doesn’t fear danger
68. The ‘danger’ that is not mentioned in the passage is ____ .
A. dust and smoke
B. a slippery ladder
C. being hurt by rock
D. elevators falling
69. According to the passage, the writer ____ .
A. was interested in what the tunnel job was like
B. took tourists into New York City’s tunnels
C. reported on the advantages of working underground
D. had a dream of being a tunnel worker
70. We learn that ____ .
A. Brain Gallagher and his father worked together
B. the police have more chances of dying than sandhogs
C. the sandhogs were working for the new tunnel
D. the city tunnel would be used as the city subway

一、初二物理光的折射透镜实验易错压轴题（难） 1．探究凸透镜成像的规律。 (1)选取焦距为10cm的凸透镜、蜡烛和光屏，将它们置于光具座上。点燃蜡烛，调整凸透镜和光屏的高度，使它们的中心与烛焰的中心大致在______； (2)当蜡烛、凸透镜在如图所示的位置时，调整光屏到______（填“A”、“B”或“C”）位置时，生活中的______（填“照相机”“投影仪”或“放大镜”）就是根据这个成像原理制成的； (3)保持凸透镜的位置不变，将蜡烛和光屏位置对调，光屏上______（填“能”或“不能”）再次看到清晰的像。若在此基础上将一个度数合适的远视眼镜放到蜡烛和凸透镜之间，还想在光屏上看到清晰的像，应将光屏适当______（填“靠近”或“远离”）凸透镜。 【答案】同一高度C投影仪能靠近 【解析】 【分析】 【详解】 (1)[1]为使烛焰的像成在光屏的中心，在做实验的过程中，调整凸透镜和光屏的高度，使烛焰、凸透镜和光屏三者中心大致在同一高度。 (2)[2]当蜡烛、凸透镜在如图所示的位置时，蜡烛在1倍焦距和2倍焦距之间，像会成在2倍焦距以外，所以光屏要调整光屏到C点。 [3]生活中的投影仪成像原理是物体在1倍焦距和2倍焦距之间，像在2倍焦距以外。(3)[4]保持凸透镜的位置不变，将蜡烛和光屏位置对调，根据光路的可逆性光屏上仍能成清晰的像。 [5]若在此基础上将一个度数合适的远视眼镜放到蜡烛和凸透镜之间，光线通过凸透镜后会会聚一些，还想在光屏上看到清晰的像，就要让光屏靠近凸透镜。 2．做“探究凸透镜成像规律”的实验。如图所示，一束平行光射向凸透镜，在光屏上得到一个最小、最亮的光斑，该凸透镜的焦距是____________cm。 (1)点燃的蜡烛、凸透镜、光屏三者在光具座上的位置如图之所示，则烛焰的像将成在光屏
