understand the language when we hear it spoken. Secondly, we must be able to speak it ourselves, with
confidence(自信) and without hesitation (犹豫). Thirdly, we must do much reading. Finally, we must be
able to write it. We must be able to make sentences that are correct in grammar.
There are no shortcuts to success in language learning. A good memory is a great help, but it is not
enough only to memorize the rules from a grammar book. It is not much learning by heart long lists(一
览表) of words and their meanings, studying the dictionary and so on. We must learn by using the
language.
If we are pleased with a few rules we have memorized, we are not really learning the language. We
must "learn through use." Practice is important. We must practise speaking and writing the language
whenever we can.

Not even three years ago, the Treo 650 smart phone looked revolutionary. But its latest successor,
the Treo 755p Palm was made public two weeks ago, feels like a relic.
The Treo"s basic concept-uniting a cell-phone, handheld organizer, miniaturized(小型的) keyboard,
touch-sensitive screen, Web and e-mail access and media playback(播放器) in one device-make sense.
But while competitors have advanced, Palm has been napping on the train tracks.
The new Treo 755p gets online no faster than last year"s model. Its basic design features few changes
from the 2004 version; its dimensions(容量) almost match those of the 2003 edition. And its operating
system and software for desktop synchronization(同步器) received their last major updates in 2002.
Over that same period of time, almost every other handheld device-Windows Mobile smart phones,
BlackBerrys, iPods and even plain old cell-phones-has seen major upgrades in capability and notable
shrinkage(缩水) in size.
The Treo 755p (available from Sprint for $280 after a $100 mail-in rebate and with a two-year
contact) only cements Palm"s status as the sick man of the smart phone business. After wasting most of
this decade on pointless reorganizations and a disastrous spin-off of its software-development group,
this company appears to have reached a state of creative bankruptcy.
As a basic organizer, the 755p remains pleasant to use. It"s like a second brain that remembers
details that might otherwise slip your mind. It can pluck(采集) useful bits of data off the Internet as
needed. It can also run thousands of useful programs, many free, that enhance(提高) its utility and
entertainment value.
But you could say the same, basically, of its immensely popular predecessors(被取代的原先
的东西). This new model"s main selling point-cellular(分格式的) internet connection that runs as fast
as most entry-level home broadband connections and can connect with a Bluetooth-equipped
computer-already debuted(首次露面的) on last year"s Treo 700p.
B. Positive
C. Critical.
D. Depressive.
B. It has a touch-sensitive screen.
C. It can be used to send e-mails.
D. It is a cell-phone.
B. IPods are of the smallest size and the best capability.
C. BlackBerrys have the best capability compared with others.
D. The Treo has little progress compared with other handheld device.
B. It has a great improvement in size.
C. It can be used to run some programs.
D. It can store information from the Internet.
hope for better rice production in lowland areas that are affected by flooding.
The genes, called SNORKEL genes, help rice grow longer stems to deal with higher water levels.
Deepwater rice generally produces low-yield (低产的) rice plants. But the researchers report they have
succeeded in introducing the genes to rice varieties that are higher-yield.
According to the report, as water levels rise, accumulation of the plant hormone (激素) ethylene
(乙烯) makes the SNORKEL genes start working, making stem growth more rapid. When the
researchers introduced the genes into rice that does not normally survive in deep water, they were able
to rescue the plants from drowning.
Motoyuki Ashikari, who headed the project, said his team is-hoping to use the gene on long grain
rice widely used in Southeast Asian to help stabilize production in flood-prone (易受洪水袭击的)
areas where rice with the flood-resistant gene is low in production ---about one---third to one-quarter
that of regular rice.
" Scientifically, the gene that we found is rare but clear proof of a biological ability to adapt to a harsh
environment," he said. "It"s a genetic strategy specifically to survive flooding."
High water levels in rice field can be a serious problem. In some areas, rains can cause water levels
to rise dangerously high during the growing season and flash flooding can fully submerge plants for days
or even weeks.
Rice is a main food for billions, and while productivity has increased dramatically since the 1960s,
yields must be doubled to meet projected requirements by 2050. More than 30 percent of Asian and
40 percent of African rice land is either lowland field or deepwater field.
Laurentius of Utrecht University said the study is significant because high-yield rice varieties cannot
survive extremes of floods. "The introduction of these genes into high-yield varieties, using advanced
breeding strategies, promises to improve the quality and quantity of rice," he said.
B. They help rice grow taller in highland regions.
C. They make rice grow tall enough to survive in deep water.
D. They make rice be ripe within a shorter time.
B. has been widely used in Southeast Asia
C. will be one third more expensive than regular rice
D. is lower in production than regular rice
B. damage
C. produce
D. kill
B. rice with SNORKEL genes will be of high quality in the future
C. high-yield rice varieties are not common nowadays
D. the quality of rice is difficult to improve
really know is that men, 2 animals, somehow 3 certain sounds to express thoughts, actions, and
things, 4 they could communicate with each other; and that later they agreed 5 certain signs, 6
letters, which could be combined to represent those sounds, and 7 could be written down. These
sounds, 8 spoken, or written in letters, we call words. The 9 of words, then, lies in their associations-the things they bring up before our minds.

| Grown-ups know that people and objects are solid. At the movies, we know that if we reach out to touch Tom Cruise, all we will feel is air. But does a baby have this understanding? To see whether babies know objects are solid, T.Bower designed a method for projecting an optical illusion (视觉影像) of a hanging ball. His plan was to first give babies a real ball, one they could reach out and touch, and then to show them the illusion. If they knew that objects are solid, and they show surprise in their faces and reach out for the illusion and found empty air, they could be expected movements. All the 16-to 24-week-old babies tested were surprised when they reached for the illusion and found that the ball was not there. Grown-ups also have a sense of object permanence. We know that if we put a box in a room and lock the door, the box will still be there when we come back. But does a baby realize that a ball that rolls under a chair does not disappear or go to never-never land? Experiments done by bower suggest that babies develop a sense of object permanence when they are about 18 weeks old. In his experiments, Bower used a toy train that went behind a screen. When 1  6-week-old and 22-week-old babies watched the toy train disappear behind the left side of the screen,they looked to the right, expecting it to reappear. If the experimenter took the train off the table and lifted the screen, all the babies seemed surprised not to see the train. This seems to show that all the babies had a sense of object permanence. But the second part of the experiment showed that this was not really the case. The researcher substituted (替换) a ball for the train when it went behind the screen. The 22-week-old babies seemed surprised and looked back to the left side for the train. But 16-week-old babies did not seem to notice the switch (更换). Thus, the 16-week-old babies seemed to have a sense of "something permanence," while the 22-week-old babies had a sense of object permanence related to a particular object. | |||

| A. babies" sense of sight B. effects of experiments on babies C. babies" understanding of objects D. different tests on babies" feelings | |||

| A. A chair B. A screen C. A film D. A box | |||
| 4. Which of the following statements is true? | |||
