Once upon a time, a blind man was sitting at the roadside with a hat by his feet. There was a sign beside him, {#blank#}1{#/blank#} (say), “I am blind. Please help me.” {#blank#}2{#/blank#} good many passers-by walked by him, but few of them helped him.

    A creative young man named Tom was going to his office. While walking by the blind man, he stopped {#blank#}3{#/blank#}(see) that the man only had a few coins in his hat. He bent down and put a few of his own coins in the hat. Without asking for the blind man's {#blank#}4{#/blank#}(permit), he took the sign, turned it around and wrote a new message. Then he put the sign by the feet of the blind man, and left.

    {#blank#}5{#/blank#} (late) that afternoon, when Tom returned to the blind man, he saw the hat {#blank#}6{#/blank#}(fill) with bills and coins. The blind man recognized his footsteps and asked if {#blank#}7{#/blank#} was he who had changed his sign. He also wanted to know {#blank#}8{#/blank#} the man had done to the sign.

    Then the young man told the blind man that he {#blank#}9{#/blank#} (write) something like this on the sign, “It is spring now, but I can't see it.” {#blank#}10{#/blank#} （hear）what the young man said, the blind man expressed his gratitude to him and went home happily.

    On a clear February morning, a California black bear was set free. Looking around, he {#blank#}1{#/blank#}(skillful) climbed the nearest tree. From high above the ground, he could see the hundreds of acres{#blank#}2{#/blank#}were now his home. His eyes were filled with {#blank#}3{#/blank#}(curious)

The bear had come a long way. Last fall, the seven-month-old bear bub(幼兽) was found all alone. He had no mother to care for him. He was thin,{#blank#}4{#/blank#} (weight) only 20 pounds—-about half the normal weight for a bear that age. Luckily the bub{#blank#}5{#/blank#}(bring) to The Fund for Animals Wildlife Center in Ramona, California. At the center, the bub shared{#blank#}6{#/blank#} outdoor enclosure(围栏) with another bear. There were trees to climb and places for them to dig dens(兽穴).{#blank#}7{#/blank#} (teach) the cub to find his own food, people working at the center {#blank#}8{#/blank#}(hide) fruit in tree branches. Soon, the bear was an expert at climbing trees and "picking" the fruit. All the staff felt{#blank#}9{#/blank#}(amaze) at his adaptability.

Finally, the day had come. With his new skill and strong body, the bub was ready to be{#blank#}10{#/blank#}his own, and ready to live like a bear should— in the wild.

    Agricultural experts say crop diversity is important to feed the{#blank#}1{#/blank#}(increase) population of our planet. They say having a large variety of plants also{#blank#}2{#/blank#}(help) to protect against possible crop diseases and future crises. But many experts say the number has decreased sharply during the past century.

    One of the world's {#blank#}3{#/blank#}(large) seed conservation projects has predicted further losses. The Millennium Seed Bank Partnership is warning that up to one hundred thousand plant species could {#blank#}4{#/blank#} (permanent) disappear. The rich collection of genes{#blank#}5{#/blank#} decide their qualities would disappear with them.

    Many experts blame climate change and loss of habitat, normal growth area, for damaging plant life. They say human{#blank#}6{#/blank#}(activity) and poorly planned, overly heavy use of land also are responsible. Modern business farming is responsible{#blank#}7{#/blank#}loss of farmers' traditional crop varieties. The "Green Revolution" of the twentieth century changed agriculture. Some experts say the use of modern commercial farming methods saved millions of people from{#blank#}8{#/blank#}(starve). Farmers planted, watered, and fertilized their crops with the help of machines. They treated their fields with chemicals{#blank#}9{#/blank#}(control) diseases and insects. Harvests grew larger and higher quality,{#blank#}10{#/blank#} another result was that some traditional crops were lost. Damage to the environment over the past century makes people believe that crop diversity also suffered.

    The Hong Kong –Zhuhai–Macao Bridge, the world's {#blank#}1{#/blank#} (long) cross-sea bridge, enters the history of human engineering and connection as a point of pride upon {#blank#}2{#/blank#} (it) opening to traffic at 9 a. m. on Oct. 24, 2018.

    One day after the opening was announced at a ceremony {#blank#}3{#/blank#} (hold) in Zhuhai, the bridge's ports in three different administrative regions started serving travelers around the clock, opening 24 hours a day, seven days a week. {#blank#}4{#/blank#} (ensure) faster boundary crossings for passengers, the Macao and Zhuhai ports jointly use a one-off immigration model, {#blank#}5{#/blank#} allows travelers to queue up only once to finish both exit and entry procedures of the two cities in about thirty {#blank#}6{#/blank#} (second).

    Apart {#blank#}7{#/blank#} private cars, taxis and goods vehicles, two types of public transportation—shuttle bus and cross-boundary coach—can also run on the HZMB. {#blank#}8{#/blank#} frequency of shuttle buses is about 5-10 minutes during peak hours. Booking tickets for the shuttle bus online in advance {#blank#}9{#/blank#} (be) available since 9 am on Tuesday. With the bridge now in service, the travelling time between Zhuhai and Hong Kong International Airport will {#blank#}10{#/blank#} (shorten) from 4 hours to 45 minutes.

    Our world has seen {#blank#}1{#/blank#} increasing number of students pressuring their parents into buying luxuries (奢侈品) just to look good before their peers. Problem is {#blank#}2{#/blank#} is to blame, parents, students or society? Now, some schools have taken action.

    To avoid {#blank#}3{#/blank#} (show) off superiority among wealthy students, Woodchurch High School in northwestern England has recently made an {#blank#}4{#/blank#} (announce) to refuse quality designer coats, including Canada Goose, often worth hundreds of dollars. Such coats make poor students feel bad since these items lead to inequality. "They feel left out and inadequate," {#blank#}5{#/blank#} (say) The Independent in its last issue.

    The ban has aroused nationwide debate. Some argue that we shouldn't take away parents' right to buy anything {#blank#}6{#/blank#} (value) they like for their kids. However, most parents applaud, believing it decreases their worries on lower incomes.

    Just as Libby Purves, a UK reporter, put it, how you feel at school largely affects your whole life. Columnist Michelle Singletary wrote on The Washington Post that now comes the {#blank#}7{#/blank#} (big) chance so far to teach students {#blank#}8{#/blank#} (understand) clothing in fact measures nothing.

    Not just this. In May St. Wilfrid's Primary School banned students {#blank#}9{#/blank#} using designer pencils in case poor students would feel {#blank#}10{#/blank#} (look) down upon.
