1 . Which is safer-staying at home, traveling to work on public transport, or working in the office? Surprisingly, each of these carries the same risk, which is very low. However, what about flying compared to working in the chemical industry? Unfortunately, the former is 65 times riskier than the latter! In fact, the accident rate of workers in the chemical industry is less than that of almost any of human activity, and almost as safe as staying at home.

The trouble with the chemical industry is that when things go wrong they often cause death to those living nearby. It is this that makes chemical accidents so newsworthy. Fortunately they are extremely rare. The most famous ones happened at Texas City (1947), Flixborough( 1974), Seveso (1976), Pemex (1984) and Bhopal (1984).

Some of these are always in the minds of the people even though the loss of life was small. No one died at Seveso, and only 28 workers at Flixborough. The worst accident of all was Bhopal, where up to 3,000 were killed. The Texas City explosion of fertilizer killed 552. The Pemex fire at a storage plant for natural gas in the suburbs of Mexico City took 542 lives, just a month before the unfortunate event at Bhopal.

Some experts have discussed these accidents and used each accident to illustrate a particular danger. Thus the Texas City explosion was caused by tons of ammonium nitrate (硝酸氨), which is safe unless stored in great quantity. The Flixborough fireball was the fault of management, which took risks to keep production going during essential repairs. The Seveso accident shows what happens if the local authorities lack knowledge of the danger on their doorstep. When the poisonous gas drifted over the town, local leaders were incapable of taking effective action. The Pemex fire was made worse by an overloaded site in an overcrowded suburb. The fire set off a chain reaction of exploding storage tanks. Yet, by a miracle, the two Largest tanks did not explode. Had these caught fire, then 3,000 strong rescue team and fire fighters would all have died.

7 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

Sean turned to look at his father, who was standing confidently on his new sailboat. Sean hated it that he couldn’t remember all of the sailing terms (术语) and skills his dad taught him. However, he pushed himself to ask, expecting his father’s response. “Which way are we turning?” “We’re coming about” his father said firmly. “That means we are turning into the wild. That way.” His father said, pointing to the right side of the boat. “Time for you to make a bowline knot (单套结)!”

Sean reached for a rope and tried his best to make one. His father had taught him the skill dozens of times, which could not only help moor (停泊) the boat but also save everyone in emergency. After practising several times, he finally knew how to do this correctly and quickly. He looked back at his father, hoping for a praise. But his dad was looking up at the sail (帆), not at him. He untied the knot and dropped the rope under the seat, filled with a sense of loss.

He looked up at the sky. Dark clouds gathered overhead and the wind began blowing. “Hey, Sean, come and take the wheel for a minute!” His father ordered. Sean didn’t want to, not did he want to see that disappointing look on his father’s face. “Uh, year!” Sean locked the sail in place and went to keep the wheel.

“Just keep her going straight. I’m going to check something.” Sean held the wheel tightly. Suddenly, the wind changed direction. The boat shook sharply and even tipped (倾斜) to one side. “Dad!” he called, but no response. He didn’t see him anywhere on the sailboat. Just then, the water became calm a little. Sean caught the chance to look the wheel quickly. He looked out at the huge crashing waves. Then he saw it--- a flash of a figure.

Much to his surprise, the figure in the water was his dad!

8 . Most people are hoping the recent stranding (搁浅) of the 1,300-foot, 220,000-ton Ever Given container ship (集装箱货运船) in the Suez Canal was a one-off---just a case of a very big ship getting stuck in a narrow waterway. However, more than 100 ships of similar size are passing through the world’s waterways, and even bigger ones are being built.

Capt.Andrew Kinsey, a senior marine-risk consultant (海洋风险顾问) for a global financial services firm, says with heavy weather in the North Pacific Ocean over the past year, a lot of containers are going overboard (落水). Part of the problem is the way the ultra-large ships handle at sea with towering stacks (堆叠) of containers, especially in strong winds.

Alan Murphy, chief executive of a container-shipping research and advisory firm in Copenhagen, Denmark, says it’s difficult to know whether there has been an increase in the number of containers going overboard or if trans-Pacific container losses over the past year have just received more attention.In a November report, the World Shipping Council found the number of such incidents to be falling in recent years, although the report does not cover 2020. There is no central database for reporting container losses, so it’s not known exactly how many containers fall overboard, Murphy says.

Murphy says container ships are often fully loaded nowadays, as demand for consumer products has jumped during the corona virus pandemic. “In the past, these huge ships have never really sailed as fully loaded as they are now,” he says.“Obviously, the more the ship carries, the greater the risk of an incident happening.”

“The stranding of Ever Given in the Suez Canal is a warning,” Kinsey says.“We’ve been bring up the issue of size in our yearly safety and shipping review and in papers for over five years.”

Carrying more containers needs bigger and wider ships, which means it is harder for them to sail through narrow waterways like the Suez Canal and move when they get stuck.

1. What can we imply from paragraph 1?

A．It might be a tough task to build bigger ships.

B．Costs of overseas shipments might rise sharply.

C．There might be changes in the world’s waterways.

D．More accidents like the recent stranding might happen.

2. What did the World Shipping Council find in the November report?

A．No database for reporting container losses had been created.

B．Trans-Pacific container losses had received more attention.

C．The number of container losses had dropped in recent years before 2020.

D．More container losses happened in 2020 than in the past few years.

3. What leads to fully loaded container ships nowadays according to Murphy?

A．The extreme weather.	B．The increasing size of ships
C．The slow transportation.	D．The growing demand for consumer goods.

4. What do Kinsey’s words in the 5^th paragraph show?

A．Warnings about the risks of stranding are given yearly.

B．Concern about larger ships has been voiced for some time.

C．Some container ships can carry as many goods as Ever Given.

D．Ships bigger than Ever Given won’t be allowed through the Suez Canal.

9 . People have always been attracted to rock-climbing and plenty of accidents have resulted from this hobby. Seventeen-year-old Wendy Sherlock has fallen three times without any injury while rock-climbing, but after her latest accident last Saturday, she is lucky to be alive.

Wendy has been in hospital for two days after an eight-metre fall from a rocky cliff in the Sanderson National Park. She doesn't remember much about the accident, and it's not surprising considering her injuries.

“I've got quite a bad head injury — that's the worst thing." Wendy explained. “But I've also broken my arm and a couple of my ribs (肋骨) and there's a problem with my left shoulder." She doesn't know how long she will have to stay in hospital, as the doctors haven't told her yet. However, she is realistic about her recovery. "I'll be in here for a while, and I need time to recover because I hit my head when I fell on the ground. That's why I can't remember anything about the accident.”

Wendy's doctors are certain that there's no long-lasting damage, but they've advised her to give up her dangerous sport. However, Wendy is undeterred. "Since I was a child, I've always loved climbing and I decided to continue doing it," she said. "I think this accident is simply a reminder to take a little more care. I've started to feel better already, and I can't wait to start climbing again."

1. What can we know from the first paragraph?

A．Wendy is experienced in mountain climbing.	B．Wendy never had accidents while rock-climbing.

3. What does the underlined word “undeterred” mean in the last paragraph?

A．Not confused.

B．Not determined.

C．Not satisfied.

D．Not discouraged.

4. Which of the following can be the best title?
