19.The number of guests invited to the party______ fifty,but a number of them______ absent.(  )
A.were;wasB.were;wereC.was;wereD.was;was

分析 邀請參加聚會的客人數(shù)量有50個,但大部分都缺席.

解答 答案:C
The number of guests 意為"…的數(shù)量"做主語時,謂語需用單數(shù),a number of 意為"大量的"做主語時,謂語需用復數(shù),所以答案為C.

點評 考查主謂一致,The number of,a number of做主語時,謂語選擇需熟練掌握.

17.Don't we all know a"Happy Meal"when we see one-the famous boxed meal that includes a hamburger,a kid-sized portion of fries,a drink and so on,served with a toy that's extremely popular with children who love to collect them?
But collectors of these little toys will soon be in for a surprise.For the book lovers though,there is some good news.Mc Donalds will replace toys with books.However,each of these books will mainly pass on nutritional messages.
Do you know that Mc Donalds has been marketing the boxed kid's meal since 1979?Happy Meals are extremely popular with kids,especially for its collectible toys,when you consider that over 1.3 billion of these packages are sold each year!These packages have been very controversial.Health supporters believe that drawing kids to these meals with toys is a clever way of promoting unhealthy food choices.They see it as an advertising strategy of"catching its customers young"-a move that has paid off very well for the fast food company.
Child development experts say that food habits get formed in children by age six and continue through to their adult life.Fatty and sugary foods such as those served in Mc Donalds'Happy Meals are believed to play a big role in growing health problems such as obesity and diabetes.Public health care costs have gone up and untold amounts of other health problems.In 2010,the State of California tried to ban toys in Happy Meals.But it was strongly opposed by some as being heavy-handed,and the ban was thrown out by the government.
While some people believe that Mc Donalds,with its large following of children,can create a powerful message through the books,others believe its actions are contradictory.Anyway,the company is trying to spread the message of nutrition while it is serving food that is anything but healthy.
28.What's the aim of the question raised in the first paragraph?D
A.To give a surprise to the book lovers.
B.To persuade the readers to buy boxed meals.
C.To make the readers think about the answer.
D.To get the readers'attention to the passage.
29.Books will be added into Happy Meals toC.
A.encourage more kids to read books
B.introduce the history of McDonald's
C.have kids learn more about nutrition
D.help young kids learn to read and write
30.In the author's opinion,Happy MealsB.
A.bring much fun to children
B.do no actual good to children's health
C.a(chǎn)re popular with the young and the old
D.teach children a lot about nutrition
31.Which of the following can be the best title for the passage?A
A.Are Happy Meals Really Happy?
B.The links Between Food and Health
C.The Importance of Eating Healthy Food
D.Happy Meal-A New Advertising Method.
