4.-I'm sorry.I ________ at you the other day.
-Forget it.I was a bit out of control myself.(  )
A.shouldn't shoutB.couldn't have shouted
C.mustn't shoutD.ought not to have shouted

分析 --很抱歉.我那一天本不应该对你大吼.
--别放在心上.我自己也有点失控了.

解答 答案是D.本题考查"情态动词+have done"的结构.the other day几天前;对过去的或已经发生是事件的说明用"情态动词+have done"的结构,所以排除A和C;couldn't have done 不可能已经…;ought not to  have done是虚拟语气,表示"本不应做但事实上却做了;根据句意可知,"我那一天本不应该对你大吼",由此判断答案选择D.

点评 在掌握虚拟语气的规则的基础上,判断题干属于什么类型的虚拟,然后根据语境,选用恰当的动词形式表达虚拟.

12.A MAJOR breakthrough that could save many lives could be coming,as a simple blood test from genomics (基因组学) company Illumina could help to detect (发现)cancer early.
The company,helped by $100 million (about 658 million yuan)from famous tech founders like Bill Gates and Jeff Bezos,aims to find warning signs of any type of cancer before there are any symptoms or tumors (肿瘤),and thus save many lives,according to The Telegraph.
The race to invent this type of technology is happening between several scientists.For example,the Cancer Research UK Manchester Institute and the University of Leicester in the UK are both working on similar technologies.
Although some blood treatments that show tumors returning or cancer getting worse have been developed,scientists have been trying for some time to find cancer signs in people that otherwise seem healthy.The technology,called"liquid biopsy",would work by finding parts of DNA that are known to be signs of cancer in the blood as the disease developed.
Catching cancer early isn't always a good thing-some cancers never go on to become dangerous,but treating them can have bad side effects.However,Jay Flatley,the Illumina chief executive and chairman of Grail,a company set up by Illumina,told The New York Times that Grail will solve these issues by sequencing(确定…的顺序)the DNA of 30,000 to 50,000 people.It will check how serious their cancers are over time to make the test accurate.The money of a large company like Illumina means that its DNA sequencing technologies are far more accurate than the average ones.
At the University of Leicester,researchers such as Professor Jacqui Shaw are also trying to solve the problem by analyzing bits of DNA for errors that are only related to fast-progressing tumors.
"We hope today is a turning point in the war on cancer,"said Flatley."By making it possible for cancer to be detected early in people with no symptoms through a simple blood test,we aim to greatly decrease cancer deaths by finding the disease at a stage when it can be cured."
Last year,a similar test created in London by the Institute of Cancer Research was able to tell if breast cancer was coming back almost eight months before any symptoms were found.

59.According to the article,the company IlluminaD.
A.has invented a new medicine to cure cancer
B.has found a new way to cure cancer of any kind
C.is developing a new treatment for breast cancer
D.could use a blood test to catch cancer early
60.What can be concluded from the article?C
A.Blood tests still can't discover signs of cancer returning.
B.Only scientists in the UK are making progress in cancer research.
C.Finances play an important role in research.
D.The"liquid biopsy"technology is the first blood treatment adopted in the history of cancer research.
61.The author wrote the article mainly toA.
A.inform us of a new method of detecting cancer
B.call for donations to companies doing medical research
C.compare different cancer experiments
D.stress the difficulties of medical research.
9.Bears and humans often meet in National Parks.Although campers and hikers are warned not to feed the bears,many people ignore these warnings and feed the beasts anyway.When bears are used to people's food,problems soon arise.
Bears like to eat a large variety of things,both meat and vegetable.Without human assistance,bears live nicely on roots,twigs,leaves of trees,insects and small animals.With people around,the bears'tastes quickly expand to include sandwiches,hot dogs,hamburgers,and anything else they can temp humans into giving up.
Bears often develop clever strategies for getting people to let go their food supplies.More often than not,an unsuspecting hiker has taken off his or her pack for a rest only to have a bear charge out of the woods,grab the pack and quickly disappear into the underbrush with it.Hanging the pack on a tree branch won't help.Bears have been known to climb up,jump off,and catch the pack on the way down.One mother bear stretched up with her baby on her shoulders to reach a pack stored on a pole.Many bears threaten people into giving up their supplies.Although a bear is unlikely to attack a person and would probably run away if screamed at,few people are willing to do so.Most people drop the pack and run the other way.This,of course,delights the bear.In some places,the Park Service installed some metal barrels with lids to help campers keep their supplies safe from bears.Although the bears were unable to open these containers,the effort was less than successful.Most campers,unable to tell the metal drums from rubbish cans,never used them for the intended purpose.

67.Feeding bears on people's foodB.
A.brings the people a lot of fun    B.can cause problems
C.often causes injuries and deaths  D.helps bears survive
68.If people had never fed bears,the bearsA.
A.might be satisfied with what they had originally
B.would have starved long before
C.wouldn't have enough food supply
D.would have hunted for other kind of food
69.Which of the following is TRUE?D
A.If fed on sandwiches and hot dogs,the bears would no longer eat roots,twigs and insects.
B.It's likely that bears would hurt people if the people didn't give up their food.
C.Most people would frighten away the bears that would temp their food.
D.Seeing a pack,the bear would quickly snatch it and run away with it.
70.Bear-proof containers didn't work becauseC.
A.bears were clever enough to get the food in them
B.they were left open in the open air
C.people were not sure of their use
D.they were once used as rubbish cans.
