We’re always looking for well-written reviews of books, music, movies, television shows, websites, video games and other products. When writing a review, concentrate on exactly what you liked or didn’t like. Give examples of strengths and weaknesses, be descriptive and provide background information on an author, director, actor or musician, if possible. Find professional reviews in magazines or newspapers and see how reviewers deal with their topic, but be sure to express your own voice in your review.
Grammar Hint for Reviews: When describing a book, movie, album or anything else, use the present tense.
Book Reviews
Discuss an author’s technique, strengths and weaknesses instead of focusing on the plot. Does the story flow? Is there a strong sense of character and place? Did you stay up until dawn to finish it? Is it good reading for teenagers? What influence did it have on you and why? If you’ve read other books by the same author, discuss how this book compares.
Movie Reviews
Think of the major Oscar categories and consider the performances, music, lighting and setting, etc. Do these work together? Did some hold up while others didn’t? If the movie is based on a book, discuss whether one is better than the other and why. If the movie is a remake, compare the film to its original.
Remember that a well-written movie review should discuss strengths and weaknesses. Some readers may not have seen a movie yet, so don’t give away an exciting scene or the ending!
College Reviews
Begin by providing an overview of the college, including location, size and a description of the campus and/or dorm life. Think about all aspects of your college visit. What academic, athletic and after-class programs are available? What are the students like? What makes the college different from others? Every school has strengths and weaknesses. Be objective. Consider what the school has to offer and who might enjoy or benefit the most from attending there.When writing a review, you ________.
A.cannot refer to any previous review |

I had five hours in the company of First Great Western(FGW) last weekend, on a train full of passengers, all the way from Cornwall to London. I got to know some of my fellow passengers rather well. Not through talking to them, you understand.
There was the youth who was explaining to his friend exactly how he enjoyed a party with his friends last night. Opposite him was a young woman who was very excited to be going to Lanzarote for her summer holiday. And then there was the man who I took to be a car mechanic(汽车修理工); so detailed and technical was his conversation about a second-hand Audi. Everyone had a different, noisy ringtone, and none of the mobile phone conversations I was forced to hear was interesting.
By the end of the journey, I was silently complaining about the modern world, and feeling mad with FGW who, at the very moment when our carriage fell silent, would make an announcement about the buffet car (a carriage where food and drinks are sold) either opening or closing.
FGW seems to be campaigning against peace and quietness, having removed quiet carriage spaces where passengers were requested not to use mobiles so that their trains could carry more passengers. How so? I cannot understand why FGW takes no notice of passengers like me, who have suffered a lot from hearing endless telephone conversations. I have no interest in the smallest details of others’ lives. Making people listen to boring mobile phone conversations should be regarded as a rude act.”
Every train carriage should, in theory, be quiet. Why can’t that be the standard? It is possible to change public custom and practice. It was not so long ago that sidewalks were littered with dog waste:now it’s a general rule that dog owners clean it up after their pets. And once we restore peace and quietness to trains, we can then move on and stop people bringing fast food onto them, too.How did the author get to know the three passengers?
A.From their phone conversations. |
B.Through introductions. |
C.In informal conversations. |
D.By using a mobile phone. |
At the end of the journey, the author ______.
A.became satisfied with FGW’s service |
B.felt uneasy about the silence |
C.was filled with anger |
D.went to the buffet car |
What can we learn about the author from Paragraph 4?
A.He is in support of the decision of FGW. |
B.He believes FGW will have more passengers. |
C.He dislikes hearing others’ phone conversations. |
D.He thinks it’s rude to listen to others’ conversations. |
The author mentioned the rule of cleaning up dog mess to show ____.
A.dog mess has become a serious problem |
B.quiet carriages can become the standard |
C.noise in carriages is as troubling as dog mess |
D.changing public custom and practice is difficult |
Jeri Solomon is a morning person but Jim, her husband of 11 years, is not. Early in their life, it caused a problem. “When we were planning our wedding, I wanted to have these big discussions at 8 a. m.,when I had been up for two hours and was fresh, but Jim would just be getting out of bed,” says the 46-year-old designer from Melrose, Mass. “We ended up getting into many arguments because I thought he had no interest, when really he was just still half-asleep.”
The couple learned to work around their differences over the years, but their situation isn’t uncommon, says Katherine Sharkey, professor at BrownUniversity. “More women tend to be larks, while men are like night owls(猫头鹰),” she says.
The question is:Why? The answer lies in each person’s body clock. “The body clock is about 24 hours, thanks to Earth’s 24-hour light-dark cycle,” Sharkey says. “But some people have a longer natural cycle, and some are shorter.” If yours is on the long side, you’re more likely to be a night owl. If it runs short, you’re probably an early riser. But your body clock can change over your lifetime. There’s a developmental piece-school-age children are generally early birds, while teenagers tend to be night owls, and then as they age, adults gradually turn back into morning people,” Sharkey says.
Besides the clear problems with being a night owl if you have fl day job, “night owls tend to be more low-spirited, and have a higher dependence on coffee,” Sharkey says. But the news isn’t all bad. A recent study in Belgium found that night owls can stay more focused as the day goes on, compared with early risers.
Morning people, however, also have advantages. “Larks generally sleep better, have more regular sleep, and have more flexible characters,” Sharkey says. They also tend to be happier and feel healthier than night owls, according to a recent study from the University of Toronto.Jeri Solomon and her husband ______.
A.tried to change each other’s sleeping habits |
B.often argued about small things |
C.could not understand each other |
D.got up at different times |

D.are active in the morning |
Compared with morning people, night owls ______.
A.work more flexibly |
B.feel happy more easily |
C.sleep more soundly at night |
D.get more and more focused during the day |
What is the purpose of the text?
A.To explain why we get up early or late. |
B.To advise every one of us to get up early. |
C.To tell us how to change our body clock. |
D.To point out morning people’s advantages. |
Dolphins(海豚) live in a dark underwater world. It’s often impossible to see each other or anything else around them, so sound plays an important role in their survival. To communicate with each other, dolphins produce all kinds of sounds.
Only other dolphins understand what the sounds mean. Scientists haven’t uncovered their secret communication, except for one kind of whistle. It might last less than a second, but this whistle is a big deal. Why? Because these whistles are actually names of dolphins - and every dolphin has one. Scientists call these sounds a “signature whistle.” When other dolphins hear the whistle, they know which dolphin is calling.
Dolphins often hunt by themselves but still need to stay connected to the group. Since they can’t always see each other, dolphins use their signature whistles to check in with other dolphins hundreds of yards away. “In coastal areas, dolphins exchange whistles even when they’re a third of a mile apart,” says Greg Campbell, who studies animals. That means dolphins shout out to group members that might be nearly five football fields away.
What’s amazing is who names the baby dolphin. Not the mother. Not an auntie dolphin or another group member. Scientists believe the baby dolphin itself comes up with the signature whistle. Like human babies, a baby dolphin plays with sounds throughout its first year. While testing its sound skills, a baby dolphin is doing something amazing. It’s creating or figuring out its signature whistle. How or why it chooses its signature whistle is not clear. Studies show that most of the time the signature whistle is nothing like its mother’s or group members’ whistles.
When the baby dolphin is about a year old, its signature whistle is set. It repeats it of ten so the other dolphins learn to recognize it.
Deciphering(破译) dolphin names is just the beginning of figuring out what dolphins communicate about. Do they chat about sharks? Discuss the tides? Maybe they even have a name for people. Someday scientists to decipher the rest of dolphins’ communication.Sound is important for dolphins because of ______.
A.their poor sense of direction |
B.their living environment |
C.their strong enemies |
D.their big groups |
The dolphin’s signature whistle ______.
A.lasts along time |

B.tell reader s how dolphins communicate |
C.show how lovely and clever dolphins are |
D.introduce a special sound made by dolphins |
A baby dolphin gets its name ______.
A.soon after it was born |
B.according to its size |
C.all by itself |

It’s not often a tomato that is described as so sweet “whenever people see it they just want to hug”-but this was no ordinary piece of fruit.
The heart-shaped tomato was grown by the retired worker, Rod Matless, who said he was surprised when he noticed it in his field. Mr. Matless, 69, who had a heart attack a few years ago, was so taken aback by the fruit that he decided to sell it and donate the money to the British Heart Foundation. The 64 g tomato was bought for$16 on eBay by woman from Wales - who said she planned to give it to someone special.
Mr. Matless, of Wymondham, near Norwich, said:“I spent a couple of days thinking about what to do with it and I wasn’t really sure, but this seems like a good use. I hope it will do someone somewhere a bit of good.” He added:“It’s very sweet - whenever people see it they just want to hug it.” But with the tomato’s freshness a key factor, Mr. Matless was up against the clock to send it to its new owner before it went bad. He said:“I didn’t want to send someone something horrible. I probably could have raised a bit more money with more time but I was worried about it.”
“It will certainly make a nice present for a loved one. I hope that they like it and I’m glad I got to help. It’s all been very good fun and I’ve really enjoyed growing this very special tomato.”We can learn from the text that the tomato grown by Rod Matless ______.
