Friends play an important part in our {#blank#}1{#/blank#} (life). Though we may take friendship for granted, we often don't clearly understand {#blank#}2{#/blank#} we make friends. While we get on {#blank#}3{#/blank#}(good) with many people, we are usually friends with only a few—for example, per student usually {#blank#}4{#/blank#} (have) about 6 friends. In all the cases of friendly relationships, two people like one another and enjoy {#blank#}5{#/blank#} (be) together. {#blank#}6{#/blank#}fact, as we get to know people, we take into account things like age, race, economic condition, social position, and intelligence. Although these things are not of great {#blank#}7{#/blank#} (important), {#blank#}8{#/blank#} is more difficult to get on with people when there is an obvious difference in age and background. Compared with marriage, there are no friendship ceremonies to {#blank#}9{#/blank#} (strong) the connection between two people. But the mutual（彼此的）understanding that results from common experiences and emotions does seem to create a powerful bond, {#blank#}10{#/blank#} can overcome difference in background, and break down barriers（障碍）of age, class and race.

    I am taught by many teachers in my school. Every subject has a {#blank#}1{#/blank#}(differ) teacher, but I like my math teacher {#blank#}2{#/blank#} (well). Her name is Lakshmi but we usually call her Ma'am. She is our class teacher too.

    Ma'am {#blank#}3{#/blank#} (join) us last term. She is very kind and her way of {#blank#}4{#/blank#} (teach) is so interesting and simple that we all can understand what is being taught and how it could be done. Most {#blank#}5{#/blank#} (important), Ma'am teaches math with lots of patience. {#blank#}6{#/blank#}we do not understand a problem, she will spend extra time {#blank#}7{#/blank#} (guide) us until we understand it. And we can go to her at any time during school hours for help.

    She also helps us with activities at school. When there are{#blank#}8{#/blank#}(program), she will be there to help us to get ready for the show. Even when we go on picnics, she takes good care of {#blank#}9{#/blank#}.

    To me, Ma'am is not only {#blank#}10{#/blank#} good teacher, but also our best friend. I love Ma'am and I wish her a happy life.

    The world's longest cross-sea bridge — Hongkong-Zhuhai-Macao Bridge(HZMB) opened on October 24, 2018. The Guardian described it as one of the seven {#blank#}1{#/blank#} (wonder) of the modern world. The HZMB, {#blank#}2{#/blank#} links Hongkong and Macao to the Chinese mainland city of Zhuhai, began in 2009 and cost about 120 billion yuan. It's designed {#blank#}3{#/blank#} (have) a service life of 120 years, 20 years longer than most bridges. And it's not only a bridge, but also part tunnel and part island.

    In one section, the bridge turns into a 6.7km undersea tunnel that {#blank#}4{#/blank#} (pass) through two man-made islands. The tunnel is {#blank#}5{#/blank#} world's longest undersea tunnel for road traffic, allowing large ships to continue passing through the sea area above the tunnel. The bridge's engineers had to take many environmental factors {#blank#}6{#/blank#} consideration in order to protect the surrounding environment while {#blank#}7{#/blank#} (build) the bridge. Chinese white dolphins, an {#blank#}8{#/blank#} (endanger) species living in this area, were a particular concern. The HZMB will make {#blank#}9{#/blank#} much more convenient to shorten the travel time from HongKong to Zhuhai from four hours to about 45 minutes.

    By drawing local cities and religions closer together, the bridge will aid the area's development {#blank#}10{#/blank#}(great). It is expected to drive the economic development of Hongkong, Macao and nine Guangdong cities.

    I grew up in one of the poorest communities on the south side of Atlanta, US and was raised by a single mother who didn't finish 3rd grade. Not many people expected much of me, so I had to expect something of {#blank#}1{#/blank#}.

    On my 13th birthday, I bought a poster of Harvard and put it up in my room. Being at Harvard was {#blank#}2{#/blank#} I dreamt about all the time though many people thought it was far {#blank#}3{#/blank#} my reach. I would bum the midnight oil,{#blank#}4{#/blank#} (bury) in piles of books. I'd begin my day by asking myself these two questions, "What do I want in my life?" and "Are the things I am doing today going to get me closer to that life?"

    {#blank#}5{#/blank#} (remind) myself of my goal each made it easy to say no to the same choices I saw my peers making, because those paths wouldn't have taken me closer to my goal. Asking myself those questions gave me the courage and energy to study just one more hour on my SATs when my friends were asleep; and it gave me the determination to submit（提交）just one more scholarship {#blank#}6{#/blank#} (apply) when 180 others had already turned me down.

    On March 31st, 2011, {#blank#}7{#/blank#} email arrived from Harvard. The first word was "Congratulations!" A

    month later, Harvard invited me to visit the campus {#blank#}8{#/blank#} for the first time I got to see inside Sanders Theater, tour Widener Library and eat dinner in Annenberg Hall. I couldn't wait to start my {#blank#}9{#/blank#} (explore) here.

    Who you are today is the result of the decisions that {#blank#}10{#/blank#} (make) earlier, and who you will be tomorrow will be the result of the choices you make today. Who do you want to be tomorrow?

    On a bright, warm July afternoon, Mac Hollan, a primary school teacher, was cycling alone from his home to Alaska {#blank#}1{#/blank#} he heard quick and loud breathing behind him. “Man, that's a big dog!” he thought. But when he looked to the side, he saw immediately that it wasn't a doe at all, but a wolf, quickly catching up with him. In fact, he {#blank#}2{#/blank#} (meet) some cyclists just 5 minutes before and had just set {#blank#}3{#/blank#} from a gas station, but now no one could help him.

    Mac found out his can of bear spray (喷雾) and fired at the wolf. It fell back, shaking its head. But a minute later, it was by his side again, making him more {#blank#}4{#/blank#}  (fright). He fired at the wolf {#blank#}5{#/blank#} second time, it fell back only {#blank#}6{#/blank#} (start) the chase (追赶) again quickly.

    Mac waved and yelled at passing cars but was careful not to slow down. He saw a seep uphill climb before him. He knew that once he hit the hill, he {#blank#}7{#/blank#}  (catch) up and the wolf's {#blank#}8{#/blank#} (tooth) would be tearing into his flesh.

    At this moment, Paul and Beeky were driving their car on their way to Alaska. They spotted what they, too, thought was a dog {#blank#}9{#/blank#} (run) alongside a man on a bike. As they got {#blank#}10{#/blank#} (close), they realized that the dog was a wolf. They stopped their car in front of him. Mac jumped off his bike immediately and ran for the car quickly.

    Contrary to {#blank#}1{#/blank#}some people might assume, evidence {#blank#}2{#/blank#}(show) that sharks seldom attack humans. There are three types of shark attacks. In the main type, the shark attacks you because it mistakes you {#blank#}3{#/blank#} a fish, {#blank#}4{#/blank#}when it tastes human flesh it decides  {#blank#}5{#/blank#} (give) up and swims away. In the second type, the shark {#blank#}6{#/blank#}(push) you with{#blank#}7{#/blank#}nose to find out if you are fit to be eaten, and then bites you{#blank#}8{#/blank#}it thinks you are. In the third type, the shark waits for you to swim by, and then attacks you all of{#blank#}9{#/blank#}sudden. The last two types of attack more often result in the {#blank#}10{#/blank#}(die) of humans.
